The U.S. space agency NASA says a small asteroid will pass very close to Earth Thursday, just 3,600 kilometers from our planet’s surface, well within the orbit of most geosynchronous satellites.
 

In a release on its website, NASA says the object, known as 2023 BU, poses no threat to the Earth. The agency says even if it entered the atmosphere it would turn into a fireball and largely disintegrate harmlessly, with some bigger debris potentially reaching the surface as small meteorites.

 

NASA says the object – just 3.5 to 8.5 meters across – represents one of the closest passes by a near-Earth object ever recorded. It is expected to pass over the southern tip of South America at 7:27 p.m. EST (12:27 a.m. GMT). Experts say it would not be visible without a powerful telescope.

 

The agency said the asteroid was discovered and reported Saturday by amateur astronomer Gennadiy Borisov, who operates an observatory in Nauchnyi, Crimea.

 

NASA says additional observations were reported to the Minor Planet Center, or MPC, – the internationally recognized authenticator of the position of small celestial bodies. The MPC operates from the Smithsonian Astrophysical Observatory at Harvard University in Cambridge, Massachusetts under the authority of the International Astronomical Union.

 

The data was automatically posted on the Near-Earth Object Confirmation Page website. Within three days, several observatories around the world had made dozens of observations, helping astronomers better refine 2023 BU’s orbit.

 

The Center for Near Earth Object Studies, or CNEOS, at NASA’s Jet Propulsion Laboratory in southern California analyzed the data from the MPC’s confirmation page and predicted the near miss. CNEOS calculates every known near-Earth asteroid orbit to provide assessments on potential impact hazards in support of NASA’s Planetary Defense Coordination Office.

 

JPL navigation engineer Davide Farnocchia said the CNEOS Scout impact hazard assessment system ruled out any threat of impact by the asteroid. But he said, despite very few observations, it was able to predict that the asteroid would make “an extraordinarily close approach with Earth.”  

 

“In fact, this is one of the closest approaches by a known near-Earth object ever recorded.”

An asteroid the size of a delivery truck will whip past Earth on Thursday night, one of the closest such encounters ever recorded.

NASA said it will be a near miss with no chance of the asteroid hitting Earth.

NASA said Wednesday that the newly discovered asteroid will zoom 3,600 kilometers above the southern tip of South America. That’s 10 times closer than the bevy of communication satellites circling overhead.

The closest approach will occur at 7:27 p.m. EST (9:27 p.m. local.)

Even if the space rock came a lot closer, scientists said most of it would burn up in the atmosphere, with some of the bigger pieces possibly falling as meteorites.

NASA’s impact hazard assessment system, called Scout, quickly ruled out a strike, said its developer, Davide Farnocchia, an engineer at the agency’s Jet Propulsion Laboratory in Pasadena, California.

“Despite the very few observations, it was nonetheless able to predict that the asteroid would make an extraordinarily close approach with Earth,” Farnocchia said in a statement. “In fact, this is one of the closest approaches by a known near-Earth object ever recorded.”

2023 BU

Discovered Saturday, the asteroid known as 2023 BU is believed to be between 3.5 meters and 8.5 meters feet across. It was first spotted by the same amateur astronomer in Crimea, Gennadiy Borisov, who discovered an interstellar comet in 2019. Within a few days, dozens of observations were made by astronomers around the world, allowing them to refine the asteroid’s orbit.

Earth’s gravity will alter the path of the asteroid once it zips by. Instead of circling the sun every 359 days, the rock will move into an oval orbit lasting 425 days, according to NASA.

The United States is “actively seeking to reengage” China on counternarcotics, including stopping the flow of illicit synthetic drugs like fentanyl into the U.S., said the State Department ahead of Secretary of State Antony Blinken’s visit to Beijing in early February.

U.S. officials admit engagement between the two countries on these issues “has been limited in recent months.”

“We don’t have any recent meetings to read out or to preview,” a State Department spokesperson told VOA on Tuesday, when asked if talks to combat fentanyl have been resumed after Beijing suspended collaboration with Washington on the issue in protest of then-House Speaker Nancy Pelosi’s visit to Taiwan last August.

“Though its past action has helped counter illicit synthetic drug flows, we do hope to see additional action from the PRC (People’s Republic of China) – meaningful, concrete action – to curb the diversion of precursor chemicals and equipment used by criminals to manufacture fentanyl and other synthetic drugs,” State Department spokesperson Ned Price told VOA this week.

In 2019, China added fentanyl-related substances to the list of controlled narcotic drugs.

While Beijing is no longer a major source of the synthetic opioid flowing to the United States, U.S. officials said Washington continues to see Chinese-origin precursor chemicals being used in illicit fentanyl production and other illicit synthetic drugs.

Bipartisan congressional majorities have approved legislation to prioritize U.S. efforts to combat international trafficking of covered synthetic drugs.

The FENTANYL Results Act was signed into law by U.S. President Joe Biden through the National Defense Authorization Act for Fiscal Year 2023 at the end of last year.

Fentanyl is the leading killer of Americans between the ages of 18 and 49.

The FENTANYL Results Act would authorize programs through the State Department to build foreign law enforcement capacity to detect synthetic drugs and carry out an international exchange program for drug demand reduction experts, according to Democratic Representative David Trone and Republican Representative Michael McCaul, who co-authored the bill.

Trone said his nephew died of a fentanyl overdose alone in a hotel room.

 

A recent report by the U.S. Justice Department’s Drug Enforcement Administration (DEA) underlined growing threats of an animal sedative called xylazine (often known as “tranq”) mixed with illicit fentanyl. The risk of overdose multiplies when xylazine is combined with fentanyl.

“A kilogram of xylazine powder can be purchased online from Chinese suppliers with common prices ranging from $6-$20 U.S. dollars per kilogram. At this low price, its use as an adulterant may increase the profit for illicit drug traffickers,” the DEA said in a report late last year.

On Dec. 15, 2021, the State Department announced a $5 million reward for information leading to the arrest and/or conviction of Chuen Fat Yip, a Chinese national charged in a five-count federal indictment, including manufacturing and distributing a controlled substance knowing it will be unlawfully imported into the United States.

“We have no updates on Chuen Fat Yip,” a spokesperson told VOA when asked if the Chinese government is cooperating on his case.

Israeli archaeologists said Wednesday that they are trying to uncover the meaning of a recently discovered hand imprint carved into the stone wall of an ancient moat outside Jerusalem’s Old City.

The imprint, which may been made as a “prank”, was found in a thousand-year-old moat exposed during works to expand a road in Israeli-annexed east Jerusalem near Herod’s Gate, the Israeli Antiquities Authority said.

The massive moat was hewn into the stone around all of the Old City, stretching 10 meters (33 feet) across and between two to seven meters deep and, unlike typical European ones, not filled with water.

According to the IAA, Crusaders in 1099 needed five weeks to cross it and breach the city’s walls and defenses

While the moat’s function was clear, the hand’s meaning was elusive.

“It’s a mystery, we tried to solve it,” IAA’s excavation director Zubair Adawi said in a statement.

IAA archaeologists remained uncertain who carved the hand into the rock or its significance.

The moat and hand have meanwhile been covered to enable the continued infrastructure works just below the walls that currently surround the city, built in the 16th century by Suleiman the Magnificent.

A chatbot powered by reams of data from the internet has passed exams at a U.S. law school after writing essays on topics ranging from constitutional law to taxation and torts.

ChatGPT from OpenAI, a U.S. company that this week got a massive injection of cash from Microsoft, uses artificial intelligence (AI) to generate streams of text from simple prompts.

The results have been so good that educators have warned it could lead to widespread cheating and even signal the end of traditional classroom teaching methods.

Jonathan Choi, a professor at Minnesota University Law School, gave ChatGPT the same test faced by students, consisting of 95 multiple-choice questions and 12 essay questions.

In a white paper titled “ChatGPT goes to law school” published on Monday, he and his coauthors reported that the bot scored a C+ overall.

While this was enough for a pass, the bot was near the bottom of the class in most subjects and “bombed” at multiple-choice questions involving mathematics.

‘Not a great student’

“In writing essays, ChatGPT displayed a strong grasp of basic legal rules and had consistently solid organization and composition,” the authors wrote.

But the bot “often struggled to spot issues when given an open-ended prompt, a core skill on law school exams”.

Officials in New York and other jurisdictions have banned the use of ChatGPT in schools, but Choi suggested it could be a valuable teaching aide.

“Overall, ChatGPT wasn’t a great law student acting alone,” he wrote on Twitter.

“But we expect that collaborating with humans, language models like ChatGPT would be very useful to law students taking exams and to practicing lawyers.”

And playing down the possibility of cheating, he wrote in reply to another Twitter user that two out of three markers had spotted the bot-written paper.

“(They) had a hunch and their hunch was right, because ChatGPT had perfect grammar and was somewhat repetitive,” Choi wrote.

Malawi has appealed for more than 7 million additional doses of cholera vaccine from the World Health Organization as it struggles to control a record outbreak of the bacterial illness.

The WHO donated almost 3 million doses of the vaccine to Malawi in November but those were quickly used up. Since March of last year, almost 30,000 people have been infected and nearly 1,000 have died.

The appeal for more cholera doses comes as Malawi continues to register an increase in cases that have now affected all of its 29 districts.

The spokesperson for the health ministry, Adrian Chikumbe, said talks with the WHO are underway.

“We are expecting a consignment of 7.6 million doses for 17 districts, but we are going to also consider districts that are hard hit with the current outbreak,” Chikumbe said.

The Ministry of Health said Tuesday that there is no indication Malawi will receive the vaccine any time soon because many other countries are also pressing the WHO on the same issue.

The World Health Organization first supported Malawi with 3.9 million doses of the oral cholera vaccine last May, after the outbreak was reported in March.

The country received another consignment of 2.9 million doses in November through the WHO and the U.N. children’s agency, UNICEF.

Maziko Matemba, community health ambassador in Malawi, said the vaccine shortage shows a change in attitude toward the shots.

“We had a similar situation with COVID-19 where we had low uptake when we saw more people getting sick and more people dying,” Matemba said. “So I am hoping WHO and the government of Malawi will take it as an advantage that now we have high uptake, people are demanding the vaccine. Some of us have even received calls where people want to access the vaccine. So I am hoping this time we will utilize the demand.”

Cholera is an acute diarrheal disease that can kill within hours if left untreated.

Malawi is currently battling its worst cholera outbreak in a decade, largely blamed on poor sanitation and hygiene.

The hard-hit districts include Malawi’s capital, Lilongwe, and commercial hub Blantyre

Wongani Mbale, health promotion officer for the Blantyre District Health Office, said the main cause of cholera is the use of unsafe water.

“[In] Blantyre the population is growing due to urbanization, so the source of water is so scarce, so people are resorting into using the unsafe sources of water,” Mbale said.

The Malawian government is reconnecting water kiosks in hard-hit areas. They had been disconnected because of unpaid water bills.

As the country awaits another supply of cholera vaccine, health authorities have intensified campaigns on preventive measures, like eating boiled foods, washing hands with soap before eating and using toilets.

The World Health Organization is appealing for a record $2.54 billion to assist millions of people in 54 countries facing catastrophic health emergencies triggered by multiple man-made and natural disasters.  

In launching the appeal, WHO Director General Tedros Adhanom Ghebreyesus said the world is witnessing an unprecedented convergence of crises that demand an unprecedented response. 

He said WHO is addressing an overwhelming number of intersecting health emergencies. These include climate change-related flooding in Pakistan, drought and acute hunger across the Sahel and in the greater Horn of Africa, health challenges sparked by the war in Ukraine, and the outbreaks of measles, cholera, and other killer diseases in dozens of countries. 

“The world cannot look away and hope these crises resolve themselves,” Tedros emphasized. “With funding and urgent action, we can save lives, support recovery efforts, prevent the spread of diseases within countries and across borders, and help give communities the opportunity to rebuild for the future.” 

WHO reports 80 percent of humanitarian needs globally are driven by conflict and around half of preventable maternal and child deaths occur in fragile, conflict-affected and vulnerable settings. 

The African region faces the highest burden of public health emergencies globally. In 2022, the continent accounted for 64 percent of all Grade 3, or most acute, emergencies globally. 

Fiona Braka, health emergencies operations manager in WHO’s regional office for Africa, said the continent has had to deal with conflicts and climate-driven humanitarian crises combined with new and recurrent outbreaks of diseases.

Speaking from Brazzaville, the capital of the Republic of Congo, she said dealing with these complex emergencies has not been easy. But she said support provided by WHO and partners is proving to be beneficial in many ways. She noted that member states have been making progress in dealing with emergencies as they arise. 

“For instance, the time taken by countries to detect and interrupt outbreaks is shortening,” Braka gave as an example. “The investments made to address the COVID-19 pandemic over the past three years are paying off with the region better able to cope with the virus and its health emergency response systems bolstered.” 

The 54 health crises WHO currently is assisting include 11 classified as Grade 3. They include seven African countries, along with Afghanistan, Syria, Ukraine, and Yemen.

The U.S. Food and Drug Administration is proposing switching to an annual COVID-19 vaccination campaign for the country, similar to the flu shot.

In documents posted online Monday, the agency said the new strategy would provide a simplified approach to the coronavirus vaccine. The proposed plan is set to be discussed at a meeting this week of FDA scientists and the agency’s panel of external vaccine advisers.

The FDA said most Americans would need only one annual vaccination to help protect them against the coronavirus, while others — including the elderly, the very young and those with weakened immune systems — might need a two-dose inoculation for additional protection.

Under the current vaccination system, a person must get two doses of the original COVID-19 vaccine, which targets the coronavirus that emerged in 2020. Following that, booster shots have been recommended at periodic intervals, with the latest boosters targeting both the original virus and the omicron variant.

The proposed FDA changes would do away with the system of primary vaccinations and boosters and would instead recommend for most Americans a single vaccine dose that is developed annually.

As with the flu shot, vaccine makers and independent experts would aim to develop a shot that targets the virus strains most likely to dominate in the winter season. The targeted strains could be changed every year.

The FDA is also considering making the shots interchangeable, so people would not have to keep track of which vaccine brand they receive.

The agency is hoping the changes will make it easier for Americans to continue with their COVID inoculations amid a waning interest from the public to receive repeated booster shots.

While more than 80% of the U.S. population has had at least one vaccine dose, only 16% of eligible Americans have received the latest booster shot, according to The Associated Press.

The proposed FDA changes also come as experts have been publicly debating how effective the latest booster shots have been at increasing protection against COVID-19, especially in healthy adults.

Some information in this report came from The Associated Press and Reuters.

Far below our feet, a giant may have started moving against us. 

Earth’s inner core, a hot iron ball the size of Pluto, has stopped spinning in the same direction as the rest of the planet and might even be rotating the other way, research suggested on Monday.

Roughly 5,000 kilometers (3,100 miles) below the surface we live on, this “planet within the planet” can spin independently because it floats in the liquid metal outer core. 

Exactly how the inner core rotates has been a matter of debate between scientists — and the latest research is expected to prove controversial.

What little we know about the inner core comes from measuring the tiny differences in seismic waves — created by earthquakes or sometimes nuclear explosions — as they pass through the middle of the Earth.

Seeking to track the inner core’s movements, new research published in the journal Nature Geoscience analysed seismic waves from repeating earthquakes over the last six decades.

The study’s authors, Xiaodong Song and Yi Yang of China’s Peking University, said they found that the inner core’s rotation “came to near halt around 2009 and then turned in an opposite direction.”

“We believe the inner core rotates, relative to the Earth’s surface, back and forth, like a swing,” they told AFP.

“One cycle of the swing is about seven decades,” meaning it changes direction roughly every 35 years, they added.

They said it previously changed direction in the early 1970s and predicted the next about-face would be in the mid-2040s.

The researchers said this rotation roughly lines up with changes in what is called the “length of day” — small variations in the exact time it takes Earth to rotate on its axis.

Stuck in the middle 

So far there is little to indicate that what the inner core does has much effect on we surface dwellers.

But the researchers said they believed there are physical links between all Earth’s layers, from the inner core to the surface. 

“We hope our study can motivate some researchers to build and test models which treat the whole Earth as an integrated dynamic system,” they said.

Experts not involved in the study expressed caution about its findings, pointing to several other theories and warning that many mysteries remain about the center of the Earth.

“This is a very careful study by excellent scientists putting in a lot of data,” said John Vidale, a seismologist at the University of Southern California.

“[But] none of the models explain all the data very well in my opinion,” he added. 

Vidale published research last year suggesting the inner core oscillates far more quickly, changing direction every six years or so. His work was based on seismic waves from two nuclear explosions in the late 1960s and early 1970s.

That timeframe is around the point when Monday’s research says the inner core last changed direction — which Vidale called “kind of a coincidence.”

Geophysicists ‘divided’  

Another theory — which Vidale said has some good evidence supporting it — is that the inner core only significantly moved between 2001 to 2013 and has stayed put since.

Hrvoje Tkalcic, a geophysicist at the Australian National University, has published research suggesting that the inner core’s cycle is every 20 to 30 years, rather than the 70 proposed in the latest study.

“These mathematical models are most likely all incorrect because they explain the observed data but are not required by the data,” Tkalcic said.

“Therefore, the geophysical community will be divided about this finding and the topic will remain controversial.”

He compared seismologists to doctors “who study the internal organs of patients’ bodies using imperfect or limited equipment.” 

Lacking something like a CT scan, “our image of the inner Earth is still blurry,” he said, predicting more surprises ahead.

That could include more about a theory that the inner core might have yet another iron ball inside it — like a Russian doll.

“Something’s happening and I think we’re going to figure it out,” Vidale said. “But it may take a decade.”

The World Health Organization has called for “immediate and concerted action” to protect children from contaminated medicines after a spate of child deaths linked to cough syrups last year. 

In 2022, more than 300 children — mainly younger than 5 years old — in Gambia, Indonesia and Uzbekistan died of acute kidney injury, deaths that were associated with contaminated medicines, the WHO said in a statement on Monday. 

The medicines, over-the-counter cough syrups, had high levels of diethylene glycol and ethylene glycol. 

“These contaminants are toxic chemicals used as industrial solvents and antifreeze agents that can be fatal even taken in small amounts, and should never be found in medicines,” the WHO said. 

It said seven countries had reported finding the contaminated syrups in the last four months, and called for action across its 194 member states to prevent more deaths. 

“Since these are not isolated incidents, WHO calls on various key stakeholders engaged in the medical supply chain to take immediate and coordinated action,” WHO said.

The World Health Organization is calling for the total elimination of trans fat — an artificial toxic chemical commonly found in packaged foods, baked goods, cooking oils, and spreads which is responsible for half a million premature deaths each year. 

WHO reports 5 billion people are being exposed to this toxic product, increasing their risk of heart disease and death. 

Tom Frieden, the president and chief executive officer of the public health initiative Resolve to Save Lives, said that the global elimination of trans fat from food could prevent up to 17 million deaths from cardiovascular diseases by 2040. 

Frieden also spoke of the importance of distinguishing artificial trans fat, “which is a toxic chemical, which has no valid use in the food supply and should be eliminated,” from saturated fat, which he called “an inherent part of many food groups in which nobody is proposing to ban.” 

To put it simply, Frieden said, “Think of artificial trans fat as the tobacco of nutrition. It has no values.” 

Progress has been made since 2018 when the WHO set a goal for the global elimination of trans fat in 2023. It says 43 countries now have implemented best-practice policies for tackling trans fat in food, thus protecting 2.8 billion people from heart disease and death. 

To Frieden, however, that still leaves 5 billion people at risk from the devastating health impacts of trans fat. He said governments can stop these preventable deaths by enacting WHO’s best-practice policies. 

He noted several countries, especially Mexico, Nigeria and Sri Lanka, are very close to passing these lifesaving policies. According to him, all they need is a simple push to get them over the finish line. 

“Policy wins in one country can help encourage other countries to take action,” Frieden noted. “We hope that leaders such as India, Bangladesh, and the Philippines will be examples for all of the South and Southeast Asia region, and we hope that Nigeria, along with South Africa, which has already banned trans fat, will be a leader for Africa.” 

Friedan said experience shows the industry can adapt, innovate and replace trans fat with healthy alternatives. It is just a few large companies who continue to manufacture a toxic product.  

Friedan added that these companies will come into line when they see the days of trans fat are numbered. 

WHO reports most trans fat elimination policies have been implemented in high-income countries, mainly in the Americas and Europe, and that an increasing number of middle-income countries are following suit. As of now, however, no low-income countries have done so.

A study published in the December 2022 issue of the American Journal of Transplantation finds Canada leading the world in harvesting organs from those who received medical assistance in dying.

The study found that in Canada, Belgium, the Netherlands and Spain, a total of 286 people who sought euthanasia provided organs to save the lives of 837 people. Almost half of those donors, 136, came from Canada.

Patients who choose a medically assisted death due to suffering from cancer cannot be organ donors, due to the medications that are usually taken. Usable donors were suffering from diseases such as amyotrophic lateral sclerosis, Parkinson’s disease or multiple sclerosis.

Arthur Schafer, director of the Centre for Professional and Applied Ethics at the University of Manitoba, is pleased with the findings of the report.

“I was rather proud to learn that Canadian patients who receive medical assistance in dying have been given the opportunity to make something morally significant out of their death, by opting to give life through their organs to other patients,”‘ he said.

Nicole Scheidl, executive director of Ottawa-based Physicians for Life, had a very different reaction.

“I was shocked,” she said. “I also think that it really undermines the organ donation framework in this country.”

A longtime opponent of any form of euthanasia, Scheidl said it reminds her of suspected organ harvesting of executed prisoners in places such as the People’s Republic of China.

“I think people are concerned,” she said. “I know transplant teams would want to make sure that individuals who were euthanized were not coerced.”

Scheidl added that more questions should be asked about euthanasia in Canada. She said there is not enough oversight or data collection, and it is being expanded too fast.

Victoria-based lawyer Chris Considine represented Sue Rodriguez, who suffered from amyotrophic lateral sclerosis and made world headlines in the early 1990s for seeking a medically assisted death, which was rejected at the time by Canada’s Supreme Court.

He said the use of organs from patients who received medical assistance in dying, also known as MAID, is something he thought about back then.

“I knew that it would take 20 years for the law to change,” he said. “And that society would then gradually adapt the law to its needs and based on the experiences that Canadians had and the physicians had with MAID.”

Schafer said that, in the future, committees that approve medical assistance in dying should be required to notify organizations that counsel patients about organ donation.

“There shouldn’t be any conflict of interest,” said Schafer. “There shouldn’t be even a hint or a suggestion that maybe a patient was hustled into requesting MAID, or obtaining MAID earlier than they would themselves wish to do, because the doctors are eager to snatch their organs.”

MAID has been legal in Canada since 2016. The Canadian government is expected to delay a planned expansion of the law that would make euthanasia available to those with severe mental health issues.

The warming of the waters off the East Coast has come at an invisible, but very steep cost — the loss of microscopic organisms that make up the base of the ocean’s food chain.

The growing warmth and saltiness of the Gulf of Maine off New England is causing a dramatic decrease in the production of phytoplankton, according to Maine-based scientists who recently reported results of a yearslong, NASA-funded study. Phytoplankton, sometimes described as an “invisible forest,” are tiny plant-like organisms that serve as food for marine life.

The scientists found that phytoplankton are about 65% less productive in the Gulf of Maine, part of the Atlantic Ocean bounded by New England and Canada, than they were two decades ago. The Gulf of Maine has emerged as one of the fastest warming sections of the world’s oceans.

Potential loss of phytoplankton has emerged as a serious concern in recent years in other places, such as the Bering Sea off Alaska. The loss of the tiny organisms has the ability to disrupt valuable fishing industries for species such as lobsters and scallops, and it could further jeopardize imperiled animals such as North Atlantic right whales and Atlantic puffins, scientists said.

“The drop in the productivity over these 20 years is profound,” said William Balch, a senior research scientist with Bigelow Laboratory for Ocean Sciences in East Boothbay, Maine, who led the study. “And that has large ramifications to what can grow here. The health of the ecosystem, the productivity of the ecosystem.”

The scientists did the study using data gathered since 1998 by tracking chemical changes in the Gulf of Maine. The samples used to perform the work were gathered via commercial ferries and research vessels that run the same routes over and over.

The data showed changes between the gulf and the broader Atlantic, Balch said. Intrusions of warm water from the North Atlantic since 2008 have created a gulf that is hotter, saltier and less hospitable to the phytoplankton, the study states. The scientists published their findings last June in the Journal of Geophysical Research: Biogeosciences.

Phytoplankton are eaten by larger zooplankton, small fish and crustaceans, and they are critically important to sustaining larger marine life up the food chain such as sharks and whales. Loss of phytoplankton “will likely have negative impacts on the overall productivity” of larger animals and commercial fisheries, the study states.

Decline of fish stocks in the Gulf of Maine would be especially disruptive to American fishermen because it’s a key ground for the U.S. lobster industry. Other important species such as haddock, flounder and pollock are also harvested there.

Researchers have tracked similar warming trends in the Bering Sea, Southern Ocean and northern Barents Sea in recent years. Warming’s impact on plankton is an ongoing subject of scientific inquiry. A 2020 article in the journal Nature Communications found that climate change “is predicted to trigger major shifts in the geographic distribution of marine plankton species.”

Cyclical ocean conditions also have placed more stress on phytoplankton. An El Niño climate pattern, when surface water in the equatorial Pacific becomes warmer, can reduce phytoplankton production, the National Oceanic and Atmospheric Administration has said. The impacts include lack of anchovies off South America, fewer squid off California and less salmon in the Pacific, NOAA said.

The Maine scientists say loss of phytoplankton is also significant because the organisms absorb carbon dioxide from the atmosphere, much like plants do on land.

It’s part of the toll climate change is taking on ecosystems all over the world, said Jeff Runge, a professor in the University of Maine School of Marine Sciences, who was not involved in the study.

“There’s mounting evidence that it’s linked to climate change,” Runge said. “It’s having all kinds of effects on the system that we’re beginning to see.”

Brazil’s government has declared a public health emergency for the Yanomami people in the Amazon who are suffering from malnutrition and diseases such as malaria because of illegal mining.

The decree, signed by Health Minister Nisia Trindade on Friday, has no expiration date and allows for hiring extra personnel. It determines that the team in charge has to publish reports regarding the Indigenous group’s health and general well-being.

President Luiz Inacio Lula da Silva also created a multiministerial committee to be coordinated by his chief of staff for an initial period of 90 days. He is traveling to Roraima state’s capital, Boa Vista, where many ill Yanomami have been admitted to specialized hospitals.

The Yanomami are the largest native group in Brazil, with a population of around 30,000 that lives in an area larger than 9 million hectares (22 million acres) in the northern area of the Amazon rainforest, close to the border with Venezuela.

In recent years, specialists sounded the alarm that humanitarian and sanitary crises were taking shape. The report “Yanomami Under Attack,” written by the nonprofit Socio-Environmental Institute, points out that in 2021 the region was responsible for 50% of the malaria cases in the country. The same report said that more than 3,000 children were malnourished.

Illegal mining is the main root of the problems faced by the Yanomami people. Activists accuse miners of death threats, sexual violence and alcohol and drug abuse, especially against Indigenous children. The same report shows that the region had more than 40 illegal airstrips made by miners and that they had taken over some of the government health centers installed in the region.

Earlier this week, the Health Ministry had already designated a team for a special health mission in the Yanomami region. Lula scheduled an emergency trip to Roraima state following a report by independent local news website Sumauma, featuring shocking pictures of malnourished children.

According to the report, during the last four years of former President Jair Bolsonaro’s government, the death of children aged 5 or less had jumped 29% in comparison to the previous government. The same report shows that 570 Yanomami children died between 2019 and 2022 from curable diseases.

Lula tweeted that the government received information on the “absurd situation” of malnourishment in Yanomami children. The president will be accompanied by several of his ministers in Boa Vista.
