Man With 3 Faces: Frenchman Gets 2nd Face Transplant

In a medical first, a French surgeon says he has performed a second face transplant on the same patient — who is now doing well and even spent a recent weekend in Brittany.

Dr. Laurent Lantieri of the Georges Pompidou hospital in Paris first transplanted a new face onto Jerome Hamon in 2010, when Hamon was in his mid-30s. But after getting ill in 2015, Hamon was given drugs that interfered with the anti-rejection medicines he was taking for his face transplant.

Last November, the tissue in his transplanted face began to die, leading Lantieri to remove it.

That left Hamon without a face, a condition that Lantieri described as “the walking dead.” Hamon had no eyelids, no ears, no skin and could not speak or eat. He had limited hearing and could express himself only by turning his head slightly, in addition to writing a little.

“If you have no skin, you have infections,” Lantieri told The Associated Press on Tuesday. “We were very concerned about the possibility of a new rejection.”

In January, when a second face donor for Hamon became available, Lantieri and his team performed a second face transplant. But before undergoing the second transplant, doctors had to replace all of the blood in Hamon’s body in a monthlong procedure to eliminate some potentially worrisome antibodies from previous treatments.

“For a man who went through all this, which is like going through a nuclear war, he’s doing fine,” Lantieri said. He added that Hamon is now being monitored like any other face transplant patient.

Hamon’s first face was donated by a 60-year-old. With his second transplanted face, Hamon said he managed to drop a few decades.

“I’m 43. The donor was 22. So I’ve become 20 years younger,” Hamon joked on French television Tuesday.

‘Hope’ for other patients

Other doctors applauded the French team’s efforts and said the techniques could be used to help critically ill patients with few options.

“The fact that Professor Lantieri was able to save this patient gives us hope that other patients can have a backup surgery if necessary,” said Dr. Frank Papay of the Cleveland Clinic. He said the techniques being developed by Lantieri and others could help doctors achieve what he called “the holy grail” of transplant medicine: How to allow patients to tolerate tissue transplants from others.

Dr. Bohdan Pomahac of Harvard University, who has done face transplants in the U.S., said similar procedures would ultimately become more common, with rising numbers of patients.

“The more we see what’s happening with [face transplant] patients, the more we have to accept that chronic rejection is a reality,” Pomahac said. “Face transplants will become essentially non-functional, distorted and that may be a good time to consider re-transplanting.”

He said it’s still unknown how long face transplants might last, but guessed they might be similar to kidneys, which generally last about 10 to 15 years.

“Maybe some patients will get lucky and their faces will last longer. But it will probably be more common that some will have to be replaced,” he said, noting there are still many unknowns about when chronic rejection might occur.

Lantieri said he and his team would soon publish their findings in a medical journal and that he hoped cases like Hamon would remain the exception.

“The other patients I’m following, some have had some alteration of their transplant over time, but they are doing fine,” he said. “I hope not to do any future transplants like this.”

Cambridge Analytica ex-CEO Refuses to Testify in UK

Cambridge Analytica’s ex-CEO, Alexander Nix, has refused to testify before the U.K. Parliament’s media committee, citing British authorities’ investigation into his former company’s alleged misuse of data from millions of Facebook accounts in political campaigns.

Committee Chairman Damian Collins announced Nix’s decision a day before his scheduled appearance but flatly rejected the notion that he should be let off the hook, saying Nix hasn’t been charged with a crime and there are no active legal proceedings against him.

“There is therefore no legal reason why Mr. Nix cannot appear,” Collins said in a statement. “The committee is minded to issue a formal summons for him to appear on a named day in the very near future.”

Nix gave evidence to the committee in February, but was recalled after former Cambridge Analytica staffer Christopher Wylie sparked a global debate over electronic privacy when he alleged the company used data from millions of Facebook accounts to help U.S. President Donald Trump’s 2016 election campaign. Wylie worked on Cambridge Analytica’s “information operations” in 2014 and 2015.

Wylie has also said the official campaign backing Britain’s exit from the European Union had access to the Facebook data.

Cambridge Analytica has previously said that none of the Facebook data it acquired from an academic researcher was used in the Trump campaign. The company also says it did no paid or unpaid work on the Brexit campaign. The company did not respond to requests for comment from The Associated Press on Tuesday.

The Information Commissioner’s Office said Tuesday that it had written to Nix to “invite him” to be interviewed by investigators. The office is investigating Facebook and 30 other organizations over their use of data and analytics.

“Our investigation is looking at whether criminal and civil offences have been committed under the Data Protection Act,” the office said in a statement.

Nix’s refusal to appear comes as the seriousness of the British inquiry becomes more evident.

Facebook has said it directed Cambridge Analytica to delete all of the data harvested from user accounts as soon as it learned of the problem.

But former Cambridge Analytica business development director Brittany Kaiser testified Tuesday that the U.S. tech giant didn’t really try to verify Cambridge Analytica’s assurances that it had done so.

“I find it incredibly irresponsible that a company with as much money as Facebook … had no due diligence mechanisms in place for protecting the data of U.K. citizens, U.S. citizens or their users in general,” she said.

Kaiser suggested that the number of individuals whose Facebook data was misused could be far higher than the 87 million acknowledged by the Silicon Valley giant.

In an atmosphere where data abuse was rife, Kaiser told lawmakers she believed the leadership of the Leave.EU campaign had combined data from members of the U.K. Independence Party and customers from two insurance companies, Eldon Insurance and GoSkippy Insurance. The data was then sent the University of Mississippi for analysis.

“If the personal data of U.K. citizens who just wanted to buy car insurance was used by GoSkippy and Eldon Insurance for political purposes, as may have been the case, people clearly did not opt in for their data to be used in this way by Leave.EU,” she said in written testimony to the committee.

Leave.EU’s communications director, Andy Wigmore, called Kaiser’s statements a “litany of lies.”

It is how the data was used that alarms some members of the committee and has captured the attention of the public.

An expert on propaganda told the committee Monday that Cambridge Analytica used techniques developed by the Nazis to help Trump’s presidential campaign, turning Muslims and immigrants into an “artificial enemy” to win support from fearful voters.

University of Essex lecturer Emma Briant, who has for a decade studied the SCL Group – a conglomerate of companies, including Cambridge Analytica – interviewed company founder Nigel Oakes when she was doing research for a book. Oakes compared Trump’s tactics to those of Nazi leader Adolf Hitler in singling out Jews for reprisals.

“Hitler attacked the Jews, because … the people didn’t like the Jews,” he said on tapes of the interview conducted with Briant. “He could just use them to . leverage an artificial enemy. Well that’s exactly what Trump did. He leveraged a Muslim.”

Europe’s Venture Capitalists Embrace Virtual Currency Craze

Some of Europe’s biggest venture capital firms are buying into sales of new virtual coins or asking their investors to give them the freedom to do so, in a sign of mainstream investor backing for the booming but controversial crowd-funding tool.

Germany’s HV Holtzbrinck Ventures, which has more than 1 billion euros ($1.23 billion) under management, is talking to its investors about changing the terms of its next fund so it can buy tokens directly, Jan Miczaika, a partner at the firm, told Reuters.

Lakestar, the Zurich-based firm run by Klaus Hommels, has made at least four investments in crypto and blockchain-related businesses since early 2017, among them ShapeShift, an exchange, and Blockchain, a wallet provider, and it is preparing to invest in a combination of coin and equity stakes in more.

Smaller and newer funds like BlueYard Capital and Fabric Ventures are focusing specifically on investments around blockchain — a distributed ledger technology that can remove the need for centralizing institutions — often by buying virtual coins.

Venture capitalists usually take equity stakes in start-ups, gaining a say in how the company is run and legal and governance certainties over their investments. Buying into initial coin offerings (ICOs), as the sale of digital tokens is known, can be far more risky. They offer little more than a promise the tokens will be worth more in future.

But with hundreds of start-ups — ICOs last year raised $6.3 billion — seeking to raise capital for new projects, investors say that to gain access to cutting-edge technology they need the flexibility to compete.

“It’s the internet in the early 1990s, you have to experiment,” said Nicolas Brand, a partner at Lakestar. “I have to find the best way of backing the best entrepreneurs and we need to be agile in how we invest.”

Regulators have raised serious questions about the transparency of ICOs and the risks of scams, although authorities in countries from Switzerland to France have disclosed plans to attract new launches.

Supporters say blockchain will disrupt industries from finance to logistics and that ICOs are a novel way of crowd-funding.

Tokens are the route to make money. They embody the idea that consumers will need to own and use them to buy services, from playing computer games to online shopping. When demand for those products spreads, the token prices will rise, creating value for earlier owners like venture capitalists.

“The [blockchain] technology is very exciting. Ninety-five percent of the tokens will go to zero. On the other hand, the other 5 percent are very interesting and could go on to revolutioniZe the market,” said Miczaika at HV Holtzbrinck.

Equity to ICO

Unlike some big U.S. funds, most big European venture capitalists are avoiding the world’s biggest ICO, by messaging app Telegram, people familiar with the funds say, citing concerns about the amount — a reported $1.7 billion — it has raised.

Broader worries about the quality of teams looking to cash in on ICOs are common, and some funds say that far from being a threat to the venture capital model, most ICOs are a fad.

Those that survive will find themselves wanting the support and hand-holding that conventional venture investment offers.

“We need to get our heads around ICOs, but I don’t see it as a threat. I don’t think I’ve missed a company which I wish I’d invested in but couldn’t because it did an ICO,” said Suranga Chandratillake, partner at London-based Balderton Capital.

To date, venture activity has focused on crypto companies like HV Holtzbrinck’s investment in ICO platform Upvest or Point Nine Capital’s stake in peer-to-peer bitcoin lender Bitbond, which tapped into the crypto-trading craze and followed on from a series of investments by well-known U.S. venture funds.

Investors said the next round of activity would target projects offering the building blocks for blockchain’s development, such as software development networks. They will benefit if the largely unproven technology matures.

Buying into the coins is necessary for aligning themselves to such projects, they argue.

“We came to the conclusion that if we really want to do decentralized tokens we have to be a part of it,” said Ciaran O’Leary, who co-founded Berlin-based BlueYard and invested in the 2017 ICO by data storage network Filecoin, which was worth an estimated $200 million.

Risks

ICOs also present major governance and legal concerns, including how to store coins safely after several large hacks.

To keep their investments safe, venture firms are looking at storing coins offline or in wallets where no transaction can take place without the agreement of multiple individuals.

Max Mersch, a partner at Fabric Ventures, said his firm had also introduced multi-year lock-ups prohibiting quick dumping of coins, to encourage longer-term investment horizons and so partners had time to shape governance.

Risks aside, venture capitalists say the potential impact of tokens is too hard to ignore.

“A token is a very powerful innovation and in the best token projects, the fund-raising is actually a byproduct,” said Lakestar’s Brand said. “The token is about activating network effects on steroids,” he said, predicting they would have the power to take on “rival monoliths like Facebook”.

Study: Diamond From the Sky May Have Come From ‘Lost Planet’

Fragments of a meteorite that fell to Earth about a decade ago provide compelling evidence of a lost planet that once roamed our solar system, according to a study published Tuesday.

Researchers from Switzerland, France and Germany examined diamonds found inside the Almahata Sitta meteorite and concluded they were most likely formed by a proto-planet at least 4.55 billion years ago.

The diamonds in the meteorite, which crashed in Sudan’s Nubian Desert in October 2008, have tiny crystals inside them that would have required great pressure to form, said one of the study’s co-authors, Philippe Gillet.

“We demonstrate that these large diamonds cannot be the result of a shock but rather of growth that has taken place within a planet,” he told The Associated Press in a telephone interview from Switzerland.

Gillet, a planetary scientist at the Federal Institute of Technology in Lausanne, said researchers calculated a pressure of 200,000 bar (2.9 million psi) would be needed to form such diamonds, suggesting the mystery planet was as least as big as Mercury, possibly even Mars.

Scientists have long theorized that the early solar system once contained many more planets — some of which were likely little more than a mass of molten magma. One of these embryo planets — dubbed Theia — is believed to have slammed into a young Earth, ejecting a large amount of debris that later formed the moon.

“What we’re claiming here,” said Gillet, “is that we have in our hands a remnant of this first generation of planets that are missing today because they were destroyed or incorporated in a bigger planet.”

Addi Bischoff, a meteorite expert at the University of Muenster, Germany, said the methods used for the study were sound and the conclusion was plausible. But further evidence of sustained high pressure would be expected to be found in the minerals surrounding the diamonds, he said.

Bischoff wasn’t involved in the study, which was published in the journal Nature Communications.

This story has been corrected to show that the meteorite fragments fell to Earth about a decade ago, not more than a decade ago.

More Than 100 Parts for NASA’s Orion Capsule to Be 3-D Printed

More than 100 parts for U.S. space agency NASA’s deep-space capsule Orion will be made by 3-D printers, using technology that experts say will eventually become key to efforts to send humans to Mars.

U.S. defense contractor Lockheed Martin, 3-D printing specialist Stratasys, and engineering firm PADT have developed the parts using new materials that can withstand the extreme temperatures and chemical exposure of deep-space missions, Stratasys said Tuesday.

“In space, for instance, materials will build up a charge. If that was to shock the electronics on a space craft, there could be significant damage,” Scott Sevcik, Vice President Manufacturing Solutions at Stratasys told Reuters.

3-D printing, or additive manufacturing, has been used for making prototypes across a range of industries for many years, but is being increasingly eyed for scale production.

The technology can help make light-weight parts made of plastics more quickly and cheaply than traditional assembly lines that require major investments into equipment.

“But even more significant is that we have more freedom with the design … parts can look more organic, more skeletal,” Sevcik said.

Stratasys’ partner Lockheed Martin said the use of 3-D printing on the Orion project would also pay off at other parts of its business.

“We look to apply benefits across our programs — missile defense, satellites, planetary probes, especially as we create more and more common products,” said Brian Kaplun, additive manufacturing manager at Lockheed Martin Space.

Orion is part of NASA’s follow-up program to the now-retired space shuttles that will allow astronauts to travel beyond the International Space Station, which flies about 260 miles (420 km) above Earth.

The agency’s European counterpart, ESA, has suggested that moon rock and Mars dust could be used to 3-D print structures and tools, which could significantly reduce the cost of future space missions because less material would need to be brought along from Earth.

IMF: World Economy Expands Next 2 Years; Growth Fades After 2020

International Monetary Fund experts say the global economy will continue growing well for the next two years, but expect expansion to slow after 2020.

IMF research director Maurice Obstfeld said Tuesday fading trade could hurt growth and, “The first shots in a potential trade war have now been fired.” He repeated a warning the international rules that nurtured “unprecedented” economic growth after World War II are at risk of being “torn apart.”

Many economists worry that Trump administration efforts to slap tariffs on China and other U.S. trading partners are sparking retaliatory taxes on U.S.-made products that raise the cost of trading and hurt demand, stifling economic growth. Administration officials disagree, and insist their trade and tax policies will boost growth and not spark soaring deficits.

Trade squabbles are a key issue this week as top economic officials and experts gather from 189 nations in Washington for meetings of the IMF and the World Bank.

Obstfeld and his colleagues are also worried that efforts to stimulate economic recovery from the 2008 recession, such as low interest rates and massive purchases of bonds, are now ending. They put the current global growth rate at 2.9 percent, and say this moment of good growth is the time to make changes in tax and other policies that will help economies weather inevitable future downturns.

Growth in advanced economies like the United States is hampered by an aging population with larger numbers of people retiring and leaving the workforce. Slow growth in productivity and high levels of government and private debt are also threats to future growth.

The IMF predicts the world’s second-largest economy, China, will expand at a 6.6 percent rate this year and 6.4 percent in 2019. The global lender says China will continue changing its economic focus from investment and manufacturing toward consumption and services, but warns that a rising debt clouds the nation’s medium-term outlook.

US, Global Tech Firms Vow Not to Aid Governments in Cyberattacks

Microsoft, Facebook and more than 30 other global technology companies on Tuesday announced a joint pledge not to assist any government in offensive cyberattacks.

The Cybersecurity Tech Accord, which vows to protect all customers from attacks regardless of geopolitical or criminal motive, follows a year that witnessed an unprecedented level of destructive cyberattacks, including the global WannaCry worm and the devastating NotPetya attack.

“The devastating attacks from the past year demonstrate that cybersecurity is not just about what any single company can do but also about what we can all do together,” Microsoft President Brad Smith said in a statement. “This tech sector accord will help us take a principled path toward more effective steps to work together and defend customers around the world.”

Smith, who helped lead efforts to organize the accord, was expected to discuss the alliance in a speech on Tuesday at the RSA cybersecurity conference in San Francisco.

The accord also promised to establish new formal and informal partnerships within the industry and with security researchers to share threats and coordinate vulnerability disclosures.

The pledge builds on an idea for a so-called Digital Geneva Convention Smith rolled out at least year’s RSA conference, a proposal to create an international body to protect civilians from state-sponsored hacking.

Countries, Smith said then, should develop global rules for cyberattacks similar to those established for armed conflict at the 1949 Geneva Convention that followed World War Two.

In addition to Microsoft and Facebook, 32 other companies signed the pledge, including Cisco, Juniper Networks, Oracle, Nokia, SAP, Dell and cybersecurity firms Symantec, FireEye and Trend Micro.

The list of companies does not include any from Russia, China, Iran or North Korea, widely viewed as the most active in launching destructive cyberattacks against their foes.

Major U.S. technology companies Amazon, Apple, Alphabet and Twitter also did not sign the pledge.

Tech Firms to Be Forced to Give Police Overseas Data Under EU Proposal

Technology companies such as Google, Microsoft and Facebook will be forced to hand over users’ data to European law enforcement officials even when it is stored on servers outside the bloc, under a law proposed by the EU on Tuesday.

The law would allow European prosecutors to force companies to turn over data such as emails, text messages and pictures stored online in another country, within 10 days or as little as six hours in urgent cases.

The European Union executive says the proposed law, which would apply to data stored inside and outside the bloc, is necessary because current legal procedures between countries to obtain such electronic evidence can drag on for months.

“Electronic evidence is increasingly important in criminal proceedings,” said European Commission Vice-President Frans Timmermans.

“We cannot allow criminals and terrorists to exploit modern and electronic communication technologies to hide their criminal actions and evade justice.”

Digital borders are a growing global issue in an era where big companies operate so-called cloud networks of giant data centers, which mean that an individual’s data can reside anywhere.

Technology companies have found themselves torn between protecting consumers’ privacy while cooperating with law enforcement. The political pressure has intensified after Islamist-inspired attacks across Europe in recent years.

The United States recently moved to address the same problem, passing a law making it clear that U.S. judges could issue warrants for data held abroad while giving companies an avenue to object if the request conflicts with foreign law.

Prosecutors and police will have to ask a judge to approve their request for electronic evidence where it concerns more sensitive data, such as the actual content of messages, emails, pictures and videos.

Fraught with complexity

The proposal will apply only in cases where crimes carry a minimum jail sentence of three years. In cases of cyber crime there will be no minimum penalty requirement.

Where companies find themselves in a conflict-of-law situation because the country where data is stored forbids them from handing it over to a foreign authority, they will be able to challenge the seizure request.

However, such extraterritorial rules are fraught with complexity, legal and privacy experts warn.

In the United States, for example, certain companies are prohibited from disclosing information to foreign governments, while in Europe consumers’ data privacy is strictly protected and companies are restricted in how they can transfer data outside the bloc.

“The Commission is proposing dangerous shortcuts to allow national authorities to obtain people’s data directly from companies, basically turning them into judicial authorities,” said Maryant Fernandez Perez, senior policy adviser at campaign group European Digital Rights.

Ultimately, the Commission hopes to start talks with the United States on a deal to help law enforcement authorities to seize evidence held on each other’s territories.

“We always think it’s useful to have an EU-U.S. coordinated approach instead of a French-U.S. approach, a Belgian-U.S. approach because that leads to fragmentation,” a Commission official said.

Robots Could Be Girls’ Ticket to Future

Eleven-year-old Hayliee Tat traveled two-and-a-half hours with her family for a sneak preview of what the future looks like with robots in it. Their destination: the robotics open house at the University of Southern California (USC). The annual event draws mainly elementary and secondary school students from Los Angeles and beyond to spark their interest in robotics and computer science.

“Not many girls and kids are in robotics,” said Tat, who was introduced to robotics, after a friend invited her to join a team that builds robots and competes with other teams through tasks the machines can perform. 

“To me, this is a great way to meet new people, learn more and just have your creativity flow out,” said Tat. 

Tat, however, is in the minority. There is an imbalance in the U.S. between the small number of computer science college graduates, and the number of available computing jobs, according to a study by global consulting firm Accenture and non-profit group Girls Who Code.

Women make up only a small percentage of people who can compete for these jobs. The National Center for Education Statistics found that in 2015, less than 18 percent of women in the U.S. graduated with a computer science degree.

The University of Southern California is trying to expose young people to robotics and computer science through the open house, where students can tour the research labs.

“We feel that if the kids can actually see the robots, hear the PhD students and the faculty members talk about what their research is and why it’s important, how robots benefit society, we see through experience that the kids get really excited,” said Katie Mills, manager of the robotics open house. She also manages the USC Viterbi School of Engineering’s K-12 STEM (science, technology engineering and math) outreach program called VAST: Viterbi Adopt-a-School, Adopt-a-Teacher.

The aim is to make robotics exciting and relevant so a student will want to learn how to code.

“Coding is like the necessary second language that everybody, especially this generation, is going to need. You know that there’s fewer people, especially women, majoring in computer science in college now than there were 30 years ago? And there are so many jobs,” said Mills. 

Not seeing the creative side of coding and not realizing there are real life applications in computer science may be reasons some women shy away from this degree.

That was the case for Caitlyn Clabaugh, who was studying fine arts and never thought about computer science until she saw how relevant it is to helping people by applying creativity.

“When there is a clear application to a real human usage, it sort of bridges the gap for me. I was interested in the arts. I was interested in all these things, then I found that I could create with computer science,” said Clabaugh, who is now a PhD candidate in computer science.

She researches how social companion robots can help children with autism.

“Definitely focusing on special needs is very special to me. I’ve struggled with dyslexia my entire life,” said Clabaugh.

Another way to attract girls to computer science, said some academics, is by dispelling the myth that coding and computer science are lonely pursuits.

Tat enjoys her robotics team because of the social element in building robots using the toy-building LEGO blocks.

“I personally love LEGO, so I think it was really fun to build LEGO and not only do you build LEGO you can do a lot of other things and it will make you smarter and the next thing you know, you’ll have a lot of friends,” said Tat.

Exposure to robotics and computer science before college is key, but not every school has the resources.

“They don’t maybe have enough robotics equipment or maybe they have teachers that are a little uncomfortable teaching computer science,” said Mills. 

Through its VAST outreach program, the University of Southern California works with area schools, its teachers and students to try and fill the gap, in hopes of attracting more underrepresented students, including girls, to pursue computer science in college.

“It’s like a fire. If you light a spark, it will go on forever,” said Tat.

FIFA Charges World Cup Host Russia for Fan Racism

FIFA charged World Cup host Russia with fan racism Tuesday, less than two months before the tournament begins.

Monkey chants were aimed at black French players, including Paul Pogba, during France’s 3-1 friendly win over Russia in St. Petersburg last month.

“Disciplinary proceedings have been opened against the Russian Football Union for this incident,” FIFA said.

Russian Deputy Prime Minister Arkady Dvorkovich, who is overseeing World Cup preparations, told state news agencies Tuesday that Russia was cracking down on racist fans.

“We’ll do anything so there are no discrimination cases,” he said. “But if that happens … there should be zero tolerance for these people.”

The RFU said it is cooperating with the FIFA investigation.

“A request has been made to the Interior Ministry to identify several persons who were involved in these incidents,” RFU anti-discrimination officer Alexei Smertin was quoted as saying Monday by the Tass news agency. “If these people’s guilt is proven, then there’s a high likelihood they won’t be allowed to attend World Cup and Russian league games.”

Russia was previously charged with racist behavior by its fans at the last two European Championships. On both occasions, the RFU paid a fine.

It’s the third racism case this season at St. Petersburg Stadium, which will host a World Cup semifinal match. Zenit St. Petersburg has twice faced UEFA charges for racism by its fans in Europa League games.

Zenit fans flew a banner praising convicted war criminal Ratko Mladic when playing a Macedonian club in November and are accused of using a racially charged term to mock an injured black player in a game against Leipzig. The second case is due to be heard by UEFA on May 31, two weeks before the World Cup begins.

Parental Diet Before Conception Affects Child’s Health

A child’s health can be compromised not only by a mother who smokes or drinks during pregnancy, but by the obesity and poor diet of both parents well before the act of procreation, researchers said Tuesday.

What a mother and father eat, and whether they are seriously overweight, in other words, can have “profound implications for the growth, development and long-term health of their children before conception,” they warned in a trio of studies.

The findings, reported in The Lancet, a leading medical journal, should heighten awareness of “preconception risk factors,” the researchers said.

“Evidence for preconceptional effect on lifetime health is now so compelling that it calls for new guidance on parental preparation for pregnancy, beginning before conception,” they concluded.

The studies — combining a review of earlier literature and new research — showed that the lifestyle habits of fathers, not just mothers, can have a direct impact on the wellbeing of offspring.

“The preconception period is a critical time when parental health — including weight, metabolism and diet — can influence the risk of future chronic diseases in children,” said Judith Stephenson, a professor and University College London and lead author of the series. “While the current focus on risk factors such as smoking and excess alcohol intake is important, we also need new drives to prepare nutritionally for pregnancy in both parents.”

Obesity in either or both parents, for example, increases the chances of heart attacks, stroke, immune disease and diabetes in offspring.

Maternal obesity is thought to enhance levels of inflammation and hormones, which can directly alter the development of the egg and embryo. This, in turn, boosts the odds of chronic disease later in life.

In men, being obese leads to deficiencies in sperm associated with many of the same conditions.

Consequences across generations

Malnutrition in mothers can also lead to developmental problems in their children, the review found.

“Consequences can extend across generations, but awareness of these links is not widespread,” the authors noted.

“Poor nutrition and obesity are rife among women of reproductive age, and differences between high-income and low-income countries have become less distinct, with typical diets falling far short of nutritional recommendations, especially among adolescents.”

The conclusions were based in part on two new analyses of women of reproductive age — 18 to 42 — in Britain and Australia.

These studies showed that women are often not “nutritionally prepared” for pregnancy, the researchers said.

Some 96 percent of the women, for example, had iron and folate intakes below the recommended levels, 14.8 milligrams and 400 micrograms per day, respectively.

Adjusting diet after a pregnancy has begun is often not good enough.

“Micronutrient supplementation started in pregnancy can correct important maternal nutrient deficiencies, but it is not sufficient to fundamentally improve child health,” they concluded.

Schools should prepare young adults — boys and girls — for future parenthood, the studies recommended, pointing out that some 40 percent of pregnancies worldwide are unplanned.

“Efforts to improve nutrition and health behavior at a population level are needed to support individual efforts among those planning ahead of the pregnancy,” the authors concluded.

As Drought Keeps Men on the Road, Mauritania’s Pastoralist Women Take Charge

Every year when the pastoralist men in Fatima Demba’s Mauritanian village return from their months-long journey to find pastures and water, the women erupt in wild celebrations.

“We draw henna tattoos on our bodies, we braid our hair, we wear our nicest clothes,” she said, re-adjusting her bright yellow and blue robe.

Yet although she longs for her husband to come home, Demba sees one benefit in his absence.

“I am in charge of everything,” she told the Thomson Reuters Foundation, sitting in the shade of a mud-brick hut in Mafoundou village. “Our money, our field of millet — even the village’s borehole is my responsibility.”

Prolonged dry spells in this southern region of Mauritania have depleted grazing land, forcing pastoralists to travel ever longer distances to search for food and water for their herds.

That gives women in these predominantly male-dominated societies newfound power to manage harvests, the family’s remaining animals and household finances, experts say.

“Women pastoralists are the first up in the morning and the last to go to bed at night,” said Aminetou Mint Maouloud, who started the country’s first association of women herders in 2014.

“Whether it’s making butter from cow milk, fetching wood or tending to ill animals, it all comes down to women,” she added.

Worsening Drought

Livestock herding is a traditional way of making a living in West Africa’s Sahel, a semi-arid belt below the Sahara, but herders have become increasingly vulnerable to food insecurity as climate change disrupts rain patterns in the region.

That is particularly true in the impoverished desert nation of Mauritania, according to El Hacen Ould Taleb, head of the Groupement National des Associations Pastorales (GNAP), a charity working with pastoralists.

“Transhumance — the seasonal migration of pastoralists and their herds to neighboring Senegal or Mali — normally starts in October but the rains were so bad last year that people started leaving in August,” he said.

His organization is helping pastoralists find smarter migration routes — with water sources and markets along the way, for example — as part of the British government-funded Building Resilience and Adaptation to Climate Extremes and Disasters (BRACED) program.

Demba, whose husband has been gone for seven months, says she does not know when he will return.

“He has no choice, he must save our animals,” she said, pausing to take a sip of a glass of green mint tea.

In the meantime, “the family depends on me,” she added.

Under-recognized

Although women play a crucial role in pastoralism, it is rarely acknowledged, according to Mint Maouloud.

“A man will listen to everything his wife whispers on the pillow, but in the morning she won’t get any credit for it,” she said.

To change that, her association has elected a council of eight women from villages around the country. Together they lobby the country’s government on pastoralism issues.

“We tell them where an animal clinic might be needed, or which markets are best for specific kinds of animals,” she explained.

Their suggestions could find an unusually understanding ear.

Since Mauritania’s livestock ministry was created in 2014, both of its leaders have been women.

Vatma Vall Mint Soueina, the current minister, says women seeking political roles is “extremely encouraging” — and that she has seen women grow in economic clout.

“We are seeing women becoming more independent, by virtue of being so active economically,” she said from her office in Nouakchott, the capital.

Financial Independence

In Hadad village, amid stretches of sand and dirt dotted with the odd wilting tree, a dozen women huddle under a large tent covered with striped rugs.

Mariem Mint Lessiyad, a tiny woman with piercing brown eyes, chats energetically to the group, interrupted only by a bleating baby goat.

She leads a cooperative of 100 pastoralist women from nearby villages who buy chickens and sheep to raise and slaughter, selling affordable portions to local families.

“There is less meat going around, so we need to be clever with how we consume it,” she said.

The women buy a sheep for 12,000 Mauritanian ouguiya ($34), for instance, and make a profit of about 2,000 ouguiya ($6) per animal, she said.

They plan to reinvest the surplus in setting up a leather goods business.

“We can’t rely on our husbands to support us financially. They are too poor, especially now that they have to spend more money on keeping our animals healthy,” Mint Lessiyad said.

Mint Maouloud and her association are trying to persuade financial institutions to make it easier for women to get loans, so groups like Mint Lessiyad’s can get ahead.

Access to finance can be problematic, she said, with some banks outright refusing to lend money to women.

“It’s important to make women herders more independent financially, so they don’t rely on their husbands’ generosity or understanding,” she added.

Toyota to Launch ‘Talking’ Vehicles in US in 2021

Toyota Motor Corp. plans to start selling U.S. vehicles that can talk to each other using short-range wireless technology in 2021, the Japanese automaker said on Monday, potentially preventing thousands of accidents annually.

The U.S. Transportation Department must decide whether to adopt a pending proposal that would require all future vehicles to have the advanced technology.

Toyota hopes to adopt the dedicated short-range communications systems in the United States across most of its lineup by the mid-2020s. Toyota said it hopes that by announcing its plans, other automakers will follow suit.

The Obama administration in December 2016 proposed requiring the technology and giving automakers at least four years to comply. The proposal requires automakers to ensure all vehicles “speak the same language through a standard technology.”

Automakers were granted a block of spectrum in 1999 in the 5.9 GHz band for “vehicle-to-vehicle” and “vehicle to infrastructure” communications and have studied the technology for more than a decade, but it has gone largely unused. Some in Congress and at the Federal Communications Commission think it should be opened to other uses.

In 2017, General Motors Co began offering vehicle-to-vehicle technologies on its Cadillac CTS model, but it is currently the only commercially available vehicle with the system.

Talking vehicles, which have been tested in pilot projects and by U.S. carmakers for more than a decade, use dedicated short-range communications to transmit data up to 300 meters, including location, direction and speed, to nearby vehicles.

The data is broadcast up to 10 times per second to nearby vehicles, which can identify risks and provide warnings to avoid imminent crashes, especially at intersections.

Toyota has deployed the technology in Japan to more than 100,000 vehicles since 2015.

The U.S. National Highway Traffic Safety Administration (NHTSA) said last year the regulation could eventually cost between $135 and $300 per new vehicle, or up to $5 billion annually but could prevent up to 600,000 crashes and reduce costs by $71 billion annually when fully deployed. 

NHTSA said last year it has “not made any final decision” on requiring the technology, but no decision is expected before December.

Last year, major automakers, state regulators and others urged U.S. Transportation Secretary Elaine Chao to finalize standards for the technology and protect the spectrum that has been reserved, saying there is a need to expand deployment and uses of the traffic safety technology.

Rocket-control Glitch Delays Launch of NASA’s Planet-hunting Satellite

An 11th-hour technical glitch prompted SpaceX to postpone its planned launch on Monday of a new NASA space telescope designed to detect worlds beyond our solar system, delaying for at least 48 hours a quest to expand astronomers’ known inventory of so-called exoplanets.

SpaceX halted the countdown a little more than two hours before its Falcon 9 rocket had been scheduled to carry the Transit Exoplanet Survey Satellite, or TESS, into orbit from the Cape Canaveral Air Force Station in Florida.

Space Exploration Technologies, as billionaire entrepreneur Elon Musk’s private launch service is formally known, said on Twitter that the blast-off was scrubbed due to unspecified problems in the rocket’s guidance control system.

The launch was rescheduled for 6:51 p.m. EDT (2251 GMT) on Wednesday.

The two-year, $337-million TESS mission is designed to build on the work of its predecessor, the Kepler space telescope, which has discovered the bulk of some 3,700 exoplanets documented during the past 20 years and is running out of fuel.

NASA expects to pinpoint thousands more previously unknown worlds, perhaps hundreds of them Earth-sized or “super-Earth”-sized — no larger than twice as big as our home planet.

Those are believed the most likely to feature rocky surfaces or oceans, and are thus considered the best candidates for life to evolve. Scientists said they hope TESS will ultimately help catalog at least 100 more rocky exoplanets for further study in what has become one of astronomy’s newest fields of exploration.

Roughly the size of a refrigerator with solar-panel wings and equipped with four special cameras, TESS will take about 60 days to reach a highly elliptical, first-of-a-kind orbit looping it between Earth and the moon every two and a half weeks.

Like Kepler, TESS will use a detection method called transit photometry, which looks for periodic, repetitive dips in the visible light from stars caused by planets passing, or transiting, in front of them.

But TESS will scan a broader swath of the heavens to focus on 200,000 pre-selected stars that are relatively nearby — some of them just dozens of light years away — and thus among the brightest as seen from Earth.

That makes them better suited for sensitive follow-up analysis of exoplanet candidates TESS locates.

TESS will concentrate on stars called red dwarfs, smaller, cooler and longer-lived than our sun. Red dwarfs also have a high propensity for Earth-sized, presumably rocky planets, making them potentially fertile ground for further scrutiny.

Kendrick Lamar Becomes First Rapper to Win Pulitzer

California rapper Kendrick Lamar on Monday became the first rapper to win the Pulitzer Prize for music, one of the most prestigious arts awards in the United States.

Lamar, 30, won the Pulitzer for his 2017 album “DAMN.” and was also the first music winner in the 100-year history of the Pulitzers to come from outside of the world of classical or jazz.

Rap officially surpassed rock in 2017 as the biggest music genre in the United States.

Lamar’s fusion of jazz, poetry and blues with social themes and love songs has made him one of the most innovative rappers of his generation.

The Pulitzer board on Monday hailed “DAMN.,” which was released in April 2017, as “a virtuosic song collection unified by its vernacular authenticity and rhythmic dynamism that offers affecting vignettes capturing the complexity of modern African-American life.”

Previous Pulitzer music winners include jazz musicians Wynton Marsalis and Ornette Coleman.

“DAMN.,” Lamar’s fourth album deals with religion, love, personal struggles and racial politics. It topped the Billboard 200 album charts for three weeks on its release last year and powered Lamar to five wins at the Grammy Awards in New York in January.

But the album failed to win the top Grammy prize – album of the year – in what was seen as a snub by music industry voters for the rap genre despite its rising popularity.

Only two hip-hop albums have ever won the Grammy for album of the year: Lauryn Hill’s “The Miseducation of Lauryn Hill” in 1999 and Outkast’s “Speakerboxxx/The Love Below” in 2004.

Lamar was born and raised in the Los Angeles suburb of Compton, the home of hip-hop pioneers NWA, and started making music as a 16-year-old.

He also produced the soundtrack for the 2018 superhero box-office hit film “Black Panther,” and performed the lead single “Pray For Me” with The Weeknd.

Weinstein Stories That Sparked #MeToo Win Pulitzer Prize

The New York Times and The New Yorker won the Pulitzer Prize for public service Monday for breaking the Harvey Weinstein scandal with reporting that galvanized the #MeToo movement and set off a worldwide reckoning over sexual misconduct in the workplace.

 

The Times and The Washington Post took the national reporting award for their coverage of the investigation into Russian meddling in the 2016 U.S. presidential election and contacts between President Donald Trump’s campaign and Russian officials.

The Press Democrat of Santa Rosa, California, received the breaking news reporting award for coverage of the wildfires that swept through California wine country last fall, killing 44 people and destroying thousands of homes.

The Washington Post also won the investigative reporting prize for revealing decades-old allegations of sexual misconduct against Senate candidate Roy Moore of Alabama. The Republican former judge denied the accusations, but they figured heavily in Doug Jones’ victory as the first Democrat elected to the Senate from the state in decades.

One of the biggest surprises of the day came in the non-journalism categories when rap star Kendrick Lamar was awarded the Pulitzer for music, becoming the first non-classical or non-jazz artist to win the prize.

The Pulitzers, American journalism’s most prestigious awards, reflected a year of unrelenting news and unprecedented challenges for U.S. media, as Trump repeatedly branded reporting “fake news” and called journalists “the enemy of the people.”

 

In announcing the journalism prizes, Pulitzer administrator Dana Canedy said the winners “uphold the highest purpose of a free and independent press, even in the most trying of times.”

 

“Their work is real news of the highest order, executed nobly, as journalism was always intended, without fear or favor,” she said.

 

A string of stories in The Times and The Washington Post shined a light on Russian interference in the presidential election and its connections to the Trump campaign and transition — ties now under investigation by special counsel Robert Mueller. The president has branded the investigation a “witch hunt.”

The Pulitzer judges commended the two newspapers for “deeply sourced, relentlessly reported coverage in the public interest.”

 

In stories that appeared within days of each other in October, The Times and The New Yorker reported that movie mogul Weinstein faced allegations of sexual harassment and assault from a multitude of women in Hollywood going back decades and had secretly paid settlements to keep the claims from becoming public.

 

The Pulitzer judges said The Times’ Jodi Kantor and Megan Twohey and The New Yorker’s Ronan Farrow produced “explosive, impactful journalism that exposed powerful and wealthy sexual predators, including allegations against one of Hollywood’s most influential producers, bringing them to account for long-suppressed allegations of coercion, brutality and victim silencing, thus spurring a worldwide reckoning about sexual abuse of women.”

The stories led to Weinstein’s ouster from the studio he co-founded, and he now faces criminal investigations in New York and Los Angeles. He has apologized for “the way I’ve behaved with colleagues in the past” but denied any non-consensual sexual contact.

The stories’ impact soon spread beyond Weinstein to allegations against other prominent men in entertainment, politics and elsewhere, toppling such figures as “Today” show host Matt Lauer, actor Kevin Spacey, newsman Charlie Rose and Sen. Al Franken.

 

Men and women, famous or not, have spoken about their own experiences of sexual harassment and assault in what has become known as the #MeToo movement.

 

Weinstein spokeswoman Holly Baird declined to comment on the Pulitzer award except to suggest similar recognition should be afforded to Tarana Burke, an activist who founded the #MeToo movement on Twitter about a decade ago to raise awareness of sexual violence.

 

In other categories, the Arizona Republic and USA Today Network won the explanatory reporting prize for a multi-format look at the challenges and consequences of building the Mexican border wall that was a centerpiece of Trump’s campaign. The project included footage from a helicopter flight along the entire, 2,000-mile border, a podcast and a virtual reality component.

 

The local reporting award went to The Cincinnati Enquirer for what judges called “a riveting and insightful” narrative and video about the heroin epidemic in the area. The paper deployed more than four dozen reporters and photographers for an intense dive into the drug’s toll over one week.

 

Work like that and the Press Democrat’s wildfire coverage show “you don’t have to have a huge budget to have a big impact,” Canedy said.

Clare Baldwin, Andrew R.C. Marshall and Manuel Mogato of Reuters won the international reporting award for their coverage of Philippines President Rodrigo Duterte’s deadly crackdown on drugs, and the news agency’s photographers received the feature photography prize for their images of the plight of Rohingya refugees who have fled Myanmar.

 

The breaking news photography award went to Ryan Kelly of The Daily Progress of Charlottesville, Virginia, who captured the moment that a car plowed into counter-protesters demonstrating against a white nationalist rally in the Virginia college town. The car killed one of the counter-demonstrators, Heather Heyer.

Kelly made the photo on his last day at the newspaper before moving on to a job at a brewery. In a text Monday, Kelly described the prize as an “incredible honor” but added: “Mostly I’m still heartbroken for Heather Heyer’s family and everybody else who was affected by that tragic violence.”

 

Rachel Kaadzi Ghansah, a freelance writer for GQ magazine, took the feature writing award for a profile of Dylann Roof, the avowed white supremacist convicted of killing nine black churchgoers in Charleston, South Carolina.

 

The commentary award went to John Archibald of Alabama Media Group in Birmingham, Alabama, for pieces on politics, women’s rights and other topics. Art critic Jerry Saltz of New York magazine won the criticism award for what the judges called his “canny and often daring perspective.”

 

Andie Dominick of The Des Moines Register received the editorial writing prize for pieces about the consequences of privatizing Iowa’s administration of Medicaid.

 

Freelance writer Jake Halpern and freelance cartoonist Michael Sloan were awarded the editorial cartooning prize for a graphic narrative in The New York Times about a family of refugees fearing deportation.

 

The Pulitzers were announced at Columbia University, which administers the prizes. This is the 102nd year of the contest, established by newspaper publisher Joseph Pulitzer.

 

Winners of the public service award receive a gold medal; the other awards carry a prize of $15,000 each.

Global Warming Mixing Up Nature’s Dinner Time, Study Says

Global warming is screwing up nature’s intricately timed dinner hour, often making hungry critters and those on the menu show up at much different times, a new study shows.

Timing is everything in nature. Bees have to be around and flowers have to bloom at the same time for pollination to work, and hawks need to migrate at the same time as their prey. In many cases, global warming is interfering with that timing, scientists said.

A first-of-its-kind global mega analysis on the biological timing of 88 species that rely on another life form shows that on average species are moving out of sync by about six days a decade, although some pairs are actually moving closer together. 

While other studies have looked at individual pairs of species and how warming temperatures have changed their migration, breeding and other timing, the study in Monday’s Proceedings of the National Academy of Sciences gives the first global look at a worsening timing problem.

These changes in species timing are considerably greater than they were before the 1980s, the study said.

“There isn’t really any clear indication that it is going to slow down or stop in the near future,” said study lead author Heather Kharouba, an ecologist at the University of Ottawa. 

For example in the Netherlands, the Eurasian sparrow hawk has been late for dinner because its prey, the blue tit, has — over 16 years — arrived almost six days earlier than the hawk.

It’s most noticeable and crucial in Washington state’s Lake Washington, where over the past 25 years, plant plankton are now blooming 34 days earlier than the zooplankton that eat them. That’s crucial because that’s messing with the bottom of the food chain, Kharouba said.

In Greenland, the plants are showing up almost three days earlier than the caribou, so more of the baby caribou are dying “because there wasn’t enough food,” Kharouba said.

With warmer temperatures, most species moved their habits earlier, but interdependent species didn’t always move at the same rate. It’s the relative speed of changes in timing that’s key, Kharouba said.

Because of the small number of species involved in small areas over different studies, Kharouba’s team could not find a statistically significant link between temperature and changes in how species sync together. But what she saw, she said, “is consistent with climate change.”

Scientists not involved in the study praised the work.

“It demonstrates that many species interactions from around the world are in a state of rapid flux,” Boston University biology professor Richard Primack said in an email. “Prior to this study, studies of changing species interactions focused on one place or one group of species.”

Director: ‘The Girl in the Spider’s Web’ to Untangle Salander’s Life

The latest cinematic installment of the smash hit “Millennium series” will reveal more details about mysterious hacker heroine Lisbeth Salander, and delve into her past, director Fede Alvarez said.

Filming for the The Girl in the Spider’s Web is under way in Sweden with British actress Claire Foy cast as the young tattooed Salander, an introvert who endures a complex relationship with journalist Mikael Blomkvist (Sverrir Gudnason).

“What I really wanted to do was to send her into a place of her life and, in this case, to her past to confront things that will hopefully reveal a bit more about who she truly is,” said the Uruguayan director behind Evil Dead and Don’t Breathe.

“When you think you know, when you think you have figured her out, she does something that changes everything you thought you knew. That’s what’s fun about her.”

The film, set for a November release, is based on the book by new author David Lagercrantz who took the series on after the death of Stieg Larsson, the author of the original best-selling trilogy.

Lagercrantz’s sequel, released in 2016, features spies from the U.S. National Security Agency and Salander’s long-missing twin sister Camilla, who has taken over their father’s criminal network.

The role of Salander was previously portrayed by American Rooney Mara in the 2011 The Girl with the Dragon Tattoo.

Foy, who won critical acclaim for her role as Britain’s Queen Elizabeth in the Netflix series The Crown, said she was excited to play the dark character alongside Gudnason, who replaces James Bond actor Daniel Craig.

“I think inside she knows who she is, but the outside have always seen her as a victim,” said Golden Globe winner Foy, showing off her new short haircut for the role in Stockholm.

“People have been taking advantage of that and I think she’s just a survivor and non-judgmental and just … I love her. I love her.”

Beyonce to Donate $100,000 for Scholarships at Black Colleges

On the back of wide praise for her two-hour performance at the Coachella music festival, Beyonce on Monday said she was offering $100,000 in scholarship money to students at four historically black colleges and universities.

The Homecoming Scholars Award Program for the 2018-19 academic year will give away $25,000 in scholarship money to a student at Xavier University of Louisiana, Wilberforce University in Ohio, Tuskegee University in Alabama and Bethune-Cookman University in Florida, the “Lemonade” album singer’s foundation said.

Beyonce’s performance at the Coachella festival in the Southern California desert on Saturday was billed as a homage to education and black American culture, featuring a marching band, performance art, choir and dance. She was supported by more than 150 performers on stage.

It was the first time a black woman headlined the two-weekend festival, one of the biggest U.S. music gatherings of the year.

“We honor all institutions of higher learning for maintaining culture and creating environments for optimal learning which expands dreams and the seas of possibilities for students,” Ivy McGregor, who administers the singer’s BeyGood foundation, said in a statement announcing the scholarship.

The more than 100 historically black U.S. colleges and universities were all established before the Civil Rights Act of 1964, when white-dominated institutions of higher education could bar African-American students.

Last year, the 36-year-old singer established a merit scholarship program to support young women.

The “Formation” singer’s Coachella performance, which was streamed live on YouTube, was hailed as an “unprecedented celebration of black cultural influence in America” by NBC News.

Trade publication Variety called Beyonce’s show, her first in more than a year, a “musical, visual and physical triumph.”

Beyonce will perform again at Coachella this Saturday, and she and her husband, rapper Jay Z, are set to begin a U.S. and European tour together in June.

British Facial Recognition Tech Firm Secures US Border Contract

A British technology firm has been awarded a contract by the U.S. Department of Homeland Security (DHS) to use biometric facial verification technology to improve border control, the first foreign firm to win such a contract in the United States.

London-based iProov will develop technology to improve border controls at unmanned ports of entry with a verification system that uses the traveler’s cell phone.

British trade minister Liam Fox said in a statement on Monday that the contract was “one example of our shared economic and security ties” with the United States.

IProov said it was the first non-U.S. firm to be awarded a contract under the Silicon Valley Innovation Program (SVIP), which is run by the DHS Science and Technology Directorate.

Immune Therapy Scores Big Win Against Lung Cancer in Study

For the first time, a treatment that boosts the immune system greatly improved survival in people newly diagnosed with the most common form of lung cancer. It’s the biggest win so far for immunotherapy, which has had much of its success until now in less common cancers. 

In the study, Merck’s Keytruda, given with standard chemotherapy, cut in half the risk of dying or having the cancer worsen, compared to chemo alone after nearly one year. The results are expected to quickly set a new standard of care for about 70,000 patients each year in the United States whose lung cancer has already spread by the time it’s found.

Another study found that an immunotherapy combo — the Bristol-Myers Squibb drugs Opdivo and Yervoy — worked better than chemo for delaying the time until cancer worsened in advanced lung cancer patients whose tumors have many gene flaws, as nearly half do. But the benefit lasted less than two months on average and it’s too soon to know if the combo improves overall survival, as Keytruda did.

All of these immune therapy treatments worked for only about half of patients, but that’s far better than chemo has done in the past.

“We’re not nearly where we need to be yet,” said Dr. Roy Herbst, a Yale Cancer Center lung expert who had no role in the studies.

Results were discussed Monday at an American Association for Cancer Research conference in Chicago and published by the New England Journal of Medicine. The studies were sponsored by the drugmakers, and many study leaders and Herbst consult for the companies.

About the drugs

Keytruda, Yervoy and Opdivo are called checkpoint inhibitors. They remove a cloak that some cancer cells have that hides them from the immune system. The drugs are given through IVs and cost about $12,500 a month.

Keytruda was approved last year as an initial treatment with chemo for the most common form of advanced lung cancer, but doctors have been leery to use it because that was based on a small study that did not show whether it prolongs life.

The new study, led by Dr. Leena Gandhi of NYU’s Perlmutter Cancer Center, gives that proof. In it, 616 patients were given chemo and some also received Keytruda. Those not given Keytruda were allowed to switch to it if their cancer worsened.

After one year, 69 percent of people originally assigned to Keytruda were alive versus 49 percent of the others — a result that experts called remarkable considering that the second group’s survival was improved because half of them wound up switching.

How much it ultimately will extend life isn’t known — more than half in the Keytruda group are still alive; median survival was just over 11 months for the others.

The Keytruda combo also delayed the time until cancer worsened — an average of nine months versus five months for the chemo-only group.

That’s a big difference for such an advanced cancer, said Dr. Alice Shaw, a Massachusetts General Hospital lung cancer expert and one of the conference leaders. “This is really a pivotal study … a new standard of care,” said Shaw, who has no ties to the drugmakers.

Rates of serious side effects were similar, but twice as many in the Keytruda group dropped out because of them. More than 4 percent of that group developed lung inflammation and three patients died of it.

The competition

Dr. Matthew Hellmann of Memorial Sloan Kettering Cancer Center in New York led a study testing the Opdivo-Yervoy combo versus chemo in a slightly different group of newly diagnosed advanced lung cancer patients.

The study design was changed after it was under way to look at results according to patients’ tumor mutation burden — a measure of how flawed their cancer genes are, according to a profiling test by Foundation Medicine. Medicare recently agreed to cover the $3,000 test for advanced cancers.

Of 679 patients, 299 had a high number of gene flaws in their tumors. In that group, survival without worsening of disease was 43 percent after one year for those on the immunotherapy drugs versus 13 percent of those on chemo. The immunotherapy drugs did not help people with fewer tumor gene flaws.

“We have a tool that helps us determine who are the patients that are most likely to benefit from this combination,” Hellmann said.

The median time until cancer worsened was about 7 months on the immunotherapy drugs versus 5.5 months for chemo. Serious side effects were a little more common in the chemo group.

Another rival, Genentech, recently announced that its checkpoint inhibitor, Tecentriq, improved survival in a study similar to the one testing Keytruda. Details are expected in a couple of months.
