Indigenous African grains such as millet and sorghum are known to be nutritious but are not popular with many, especially the Gen Zers who view the grains as food for the poor. To change this narrative, a Kenyan entrepreneur is using the grains to make snacks and breakfast cereals to promote consumption of indigenous grains and foster environmental sustainability, as Juma Majanga reports from Nairobi.

Nairobi — A polio vaccination campaign that was planned for November but postponed due to heavy rains and floods is finally taking place in three high risk counties in the northeastern part of Kenya. This comes after 13 cases of the so-called circulating vaccine-derived poliovirus type 2 (CVDPV2) were discovered last year in the area. 

This is the third round of polio vaccination targeting three high-risk counties of Mandera, Wajir and Garissa.

The goal, according to Kenya’s ministry of health and its partners, is to reach about 750,000 children under the age of five. About 238,000 children ages 6 to 15 in certain areas will also be vaccinated.

Aden Ibrahim, Garissa County director of health, explains.

“The first case, the sample was collected in June 2023. It was a child which came from the Somalia side, later became sick and went to a health facility; they [child] were investigated because they were symptomatic, and they were confirmed as having a polio positive,” he said.

Ibrahim said soon after, more cases were detected in some of the refugee camps. 

“In Hagadera camps, there were 13 confirmed cases of polio in the camps last year and that has necessitated 3 rounds of campaign to be conducted where we did the two rounds last year and this one was actually scheduled to take place last year in November,” he said.

But due to heavy rains and floods that killed 130 and displaced 89,000 the November round was postponed.

Kenya is not the only country affected by a resurgence of polio. After three decades of being polio-free, Burundi had 16 cases last year. And as of August 2023, 187 confirmed cases of circulating variant poliovirus have been reported in 21 countries in Africa Region according to the World Health Organization.

Among the many reasons this has been happening are inaccessibility to basic healthcare, conflicts and insecurity in some of the countries, and climate change, said Ibrahim.

“Polio is more of an oral-fecal transmission and because of this climate change, age of drought brings poor sanitation at the end of the day because of issue of lack of water and all those things,” he said.

The Horn of Africa region recently suffered its worst drought in decades.  

To eradicate the disease, Ibrahim points out that countries need to strengthen routine immunization, invest in a robust surveillance system, and improve their respective healthcare systems.

Polio is a highly infectious and debilitating disease that affects children under 5 causing permanent paralysis. It can also cause death in 2 to 10 percent of those paralyzed according to WHO.

new york — The U.S. syphilis epidemic isn’t abating, with the rate of infectious cases rising 9% in 2022, according to a new federal government report on sexually transmitted diseases in adults.

But there’s some unexpected good news: The rate of new gonorrhea cases fell for the first time in a decade.

It’s not clear why syphilis rose 9% while gonorrhea dropped 9%, officials at the U.S. Centers for Disease Control and Prevention said, adding that it’s too soon to know whether a new downward trend is emerging for the latter.

They are most focused on syphilis, which is less common than gonorrhea or chlamydia but considered more dangerous. Total cases surpassed 207,000 in 2022, the highest count in the United States since 1950, according to data released Tuesday.

And while it continues to have a disproportionate impact on gay and bisexual men, it is expanding in heterosexual men and women, and increasingly affecting newborns, too, CDC officials said.

Syphilis is a bacterial disease that can surface as painless genital sores but can ultimately lead to paralysis, hearing loss, dementia and even death if left untreated.

New syphilis infections plummeted in the U.S. starting in the 1940s when antibiotics became widely available and fell to their lowest number by 1998.

About 59,000 of the 2022 cases involved the most infectious forms of syphilis. Of those, about a quarter were women and nearly a quarter were heterosexual men.

“I think it’s unknowingly being spread in the cisgender heterosexual population because we really aren’t testing for it. We really aren’t looking for it” in that population, said Dr. Philip Chan, who teaches at Brown University and is chief medical officer of Open Door Health, a health center for gay, lesbian and transgender patients in Providence, Rhode Island.

The report also shows rates of the most infectious types of syphilis rose not just across the country but also across different racial and ethnic groups, with American Indian and Alaska Native people having the highest rate. South Dakota outpaced any other state for the highest rate of infectious syphilis at 84 cases per 100,000 people — more than twice as high as the state with the second-highest rate, New Mexico.

South Dakota’s increase was driven by an outbreak in the Native American community, said Dr. Meghan O’Connell, chief public health officer at the Great Plains Tribal Leaders’ Health Board based in Rapid City, South Dakota. Most Nearly all of the cases were in heterosexual people. O’Connell said STD testing and treatment was limited in isolated tribal communities and only got worse during the pandemic.

The U.S. Department of Health and Human Services last year convened a syphilis task force focused on stopping the spread of the STD, with an emphasis on places with the highest syphilis rates — South Dakota, 12 other states and the District of Columbia.

The report also looked at the more common STDs of chlamydia and gonorrhea.

Chlamydia cases were relatively flat from 2021 to 2022, staying at a rate of about 495 per 100,000, though there were declines noted in men and especially women in their early 20s. For gonorrhea, the most pronounced decline was seen in women in their early 20s as well.

Experts say they’re not sure why gonorrhea rates declined. It happened in about 40 states, so whatever explains the decrease appears to have occurred across most of the country. STD testing was disrupted during the COVID-19 pandemic, and officials believe that’s the reason the chlamydia rate fell in 2020.

It’s possible that testing and diagnoses were still shaking out in 2022, said Dr. Jonathan Mermin, director of the CDC’s National Center for HIV, Viral Hepatitis, STD and TB Prevention.

“We are encouraged by the magnitude of the decline,” Mermin said, though the gonorrhea rate is still higher now than it was pre-pandemic. “We need to examine what happened, and whether it’s going to continue to happen.”

Blantyre, Malawi — The Malawi government and the World Health Organization launched a new COVID-19 vaccination campaign on Monday in 10 of the country’s 29 districts. This is partly in response to new cases confirmed in the past three weeks in several districts across the country.

Nsanje District in southern Malawi currently leads in the number of COVID-19 cases recorded this year.

George Mbotwa, spokesperson for the district health office, said the district has registered 17 new cases in the past three weeks and some are health workers.

“Initially there were two, but we had up to eight cases that were health workers,” he said. “Some of them have now been confirmed as negative, and others are being followed up to ensure that they are fully recovered before they can resume work.”

By Monday, Malawi cumulatively recorded 89,202 confirmed COVID-19 cases, including 2,686 deaths, since the first cases were confirmed in the country in April 2020.

Malawi’s Ministry of Health says the new vaccination campaign will help boost the number of people getting the COVID-19 vaccine. Vaccination rates in some areas of Malawi are as low as 40%.

It also says the WHO-funded campaign would help avoid waste of the vaccine as was the case in 2020 when the government destroyed nearly 20,000 expired AstraZeneca doses.

Many of those doses expired due to vaccine hesitancy amid concerns of its safety and efficacy.

However, recent government public health campaigns on the importance of COVID-19 shots have helped defeat that hesitancy.

Mary Chawinga, a mother of two of Machinjiri Township in Blantyre, said she has had the vaccine and is awaiting a booster.

“And I am ready to take my children, because prevention is better than [a] cure they say,” Chawinga said. “You never know how the wave will be like this time around considering the way it was way back in 2020. We have had it in 2021, and now this is 2024.”

Another mother of two, Habeeba Nyasulu, said she received the COVID-19 doses during the first campaign and encourages others to get the shot.

“I know that we are not safe until everyone is safe,” she said. “So, let others also receive the vaccine. I know that the vaccine does not prevent us from getting infected, but it helps us when we contract it not to be critically ill.”

Maziko Matemba is a community health care ambassador in Malawi, said the COVID-19 threat is still present in the country.

“Malawi didn’t vaccinate a required number of people against COVID-19, because the targeted population was about 11 million Malawians,” Matemba said. “But we were less than half about 2 or 3 million Malawians who were able to get vaccinated.”

Matemba said the country now needs to have the vaccine in the right places and encourage more people to get vaccinated.

The Ministry of Health says the new campaign targets 10 of the country’s 29 health districts that have recently recorded new cases. These include Machinga, Blantyre, Dowa, Mzimba and Nsanje districts.

GENEVA — The World Health Organization says great progress has been made in the global elimination of industrially produced trans fat, with nearly half the world’s population protected against the harmful effects of this toxic product.

“Five years ago, WHO called on countries and the food sector to eliminate industrially produced trans fats from the food supply. The response has been incredible,” WHO Director-General Tedros Adhanom Ghebreyesus said Monday.

“So far, 53 countries have implemented best practice policies, including bans and limits on trans fats, with three more countries on the way. This removes a major health risk for at least 3.7 billion people, or 46% of the world’s population.

“These policies are expected to save 183,000 lives every year. Just five years ago, only 6% of the world’s population was protected from this toxic additive with similar policies,” Tedros said.

Trans fat is created by adding hydrogen to vegetable oil, which causes the oil to become solid at room temperature.

“It is also solid in your body, in your coronary artery,” said Tom Frieden, president and CEO of Resolve to Save Lives. “And this is why it was at one point estimated to kill half a million people per year.” 

With almost half the world covered, Frieden said millions of deaths will be prevented in the coming decades. He said the next two years will be critical, noting that the original deadline for the global elimination of trans fats has been extended from 2023 to 2025 due to the disruptions caused by the COVID-19 pandemic.

“Global elimination, according to published estimates, would prevent about 17.5 million deaths over 25 years. The progress of reducing trans fat globally show that the noncommunicable diseases can be beaten,” Frieden said.

He said this was important because “sometimes when it comes to the noncommunicable diseases, we have the sense that we can describe them, we can predict them, but we cannot stop them. In fact, we can, and the progress stopping trans fat shows that that is possible. And there are other areas, as well, where specific results are available.”

Health officials say no amount of trans fat is safe and regard it as the worst type of fat anyone can eat because it has no known nutritional benefits. Trans fat is cheap to make and is found in margarine, palm oil, fried foods, baked products, pastries and some processed foods. 

WHO reports that a high intake of trans fat increases the risk of death from any cause by 34% and from coronary heart disease by 28%. 

WHO on Monday held an awards ceremony honoring the achievements of the first five countries to have eliminated trans fat from their food supply.  

“Today, we recognize Denmark, Lithuania, Poland, Saudi Arabia and Thailand as the first countries to go beyond just adopting policies, to monitoring and enforcing them,” Tedros said.  

“Congratulations to all these countries. You are leading the world and showing what is possible. You are the first countries to be validated, but you will not be the last,” he said.

In accepting the award, Ib Petersen, Danish ambassador to the United Nations in Geneva, said studies show that trans fat elimination policies put in place in his country in 2003 have “led to a reduction of deaths from coronary disease of 11%, which is significant.”

“It also shows that it is the most financially disadvantaged groups that have benefited most from this policy,” he said.

Frieden said he hopes more nations will follow the lead of these five countries in putting in place the policies, regulations and enforcement mechanisms needed to rid the world of trans fat.

“Of the remaining burden, just five countries — China, Pakistan, Russia, Indonesia, and Iran — account for about 60% of the remaining estimated burden. If these five countries were to implement [the best practice policies], the world would get to about 85% of the estimated burden, banned or trans fat-free,” he said.

WHO reports progress remains uneven, and a lot of work is still to be done. While many low- and middle-income countries are advancing, it says there is a long way to go, especially in Africa and the western Pacific.

“Africa has the lowest policy coverage, but there have been leaders with Nigeria and South Africa implementing,” said Frieden. “South Africa is beginning the enforcement process, and Ethiopia, Ghana and Cameroon are considering regulations in the near future.  

“They understand that trans fat is not only a toxic product, but one that might be dumped on them if they do not take action when the rest of the world is banning it,” Frieden said, adding that governments and the food industry have a responsibility to ensure that does not happen.

PETALUMA, Calif. — Last month, Mike Weber got the news every poultry farmer fears: His chickens tested positive for avian flu.

Following government rules, Weber’s company, Sunrise Farms, had to slaughter its entire flock of egg-laying hens — 550,000 birds — to prevent the disease from infecting other farms in Sonoma County north of San Francisco.

“It’s a trauma. We’re all going through grief as a result of it,” said Weber, standing in an empty hen house. “Petaluma is known as the Egg Basket of the World. It’s devastating to see that egg basket go up in flames.”

A year after the bird flu led to record egg prices and widespread shortages, the disease known as highly pathogenic avian influenza is wreaking havoc in California, which escaped the earlier wave of outbreaks that devastated poultry farms in the Midwest.

The highly contagious virus has ravaged Sonoma County, where officials have declared a state of emergency. During the past two months, nearly a dozen commercial farms have had to destroy more than 1 million birds to control the outbreak, dealing an economic blow to farmers, workers and their customers.

Merced County in Central California also has been hit hard, with outbreaks at several large commercial egg-producing farms in recent weeks.

Experts say bird flu is spread by ducks, geese and other migratory birds. The waterfowl can carry the virus without getting sick and easily spread it through their droppings to chicken and turkey farms and backyard flocks through droppings and nasal discharges.

California poultry farms are implementing strict biosecurity measures to curb the spread of the disease. State Veterinarian Annette Jones urged farmers to keep their flocks indoors until June, including organic chickens that are required to have outdoor access.

“We still have migration going for another couple of months. So we’ve got to be as vigilant as possible to protect our birds,” said Bill Mattos, president of the California Poultry Federation.

The loss of local hens led to a spike in egg prices in the San Francisco Bay Area over the holidays before supermarkets and restaurants found suppliers from outside the region.

While bird flu has been around for decades, the current outbreak of the virus that began in early 2022 has prompted officials to slaughter nearly 82 million birds, mostly egg-laying chickens, in 47 U.S. states, according to the U.S. Department of Agriculture. Whenever the disease is found the entire flock is slaughtered to help limit the spread of the virus.

The price of a dozen eggs more than doubled to $4.82 at its peak in January 2023. Egg prices returned to their normal range as egg producers built up their flocks and outbreaks were controlled. Turkey and chicken prices also spiked, partly due to the virus.

“I think this is an existential issue for the commercial poultry industry. The virus is on every continent, except for Australia at this point,” said Maurice Pitesky, a poultry expert at the University of California, Davis.

Climate change is increasing the risk of outbreaks as changing weather patterns disrupt the migratory patterns of wild birds, Pitesky said. For example, exceptional rainfall last year created new waterfowl habitat throughout California, including areas close to poultry farms.

In California, the outbreak has impacted more than 7 million chickens in about 40 commercial flocks and 24 backyard flocks, with most of the outbreaks occurring over the past two months on the North Coast and Central Valley, according to the USDA.

Industry officials are worried about the growing number of backyard chickens that could become infected and spread avian flu to commercial farms.

“We have wild birds that are are full of virus. And if you expose your birds to these wild birds, they might get infected and ill,” said Rodrigo Gallardo, a UC Davis researcher who studies avian influenza.

Gallardo advises the owners of backyard chickens to wear clean clothes and shoes to protect their flocks from getting infected. If an unusual number of chickens die, they should be tested for avian flu.

Ettamarie Peterson, a retired teacher in Petaluma, has a flock of about 50 chickens that produce eggs she sells from her backyard barn for 50 cents each.

“I’m very concerned because this avian flu is transmitted by wild birds, and there’s no way I can stop the wild birds from coming through and leaving the disease behind,” Peterson said. “If your flock has any cases of it, you have to destroy the whole flock.”

Sunrise Farms, which was started by Weber’s great-grandparents more than a century ago, was infected despite putting in place strict biosecurity measures to protect the flock.

“The virus got to the birds so bad and so quickly you walked in and the birds were just dead,” Weber said. “Heartbreaking doesn’t describe how you feel when you walk in and perfectly healthy young birds have been just laid out.”

After euthanizing more than half a million chickens at Sunrise Farms, Weber and his employees spent the Christmas holiday discarding the carcasses. Since then, they’ve been cleaning out and disinfecting the hen houses.

Weber hopes the farm will get approval from federal regulators to bring chicks back to the farm this spring. Then it would take another five months before the hens are mature enough to lay eggs.

He feels lucky that two farms his company co-owns have not been infected and are still producing eggs for his customers. But recovering from the outbreak won’t be easy.

“We have a long road ahead,” Weber said. “We’re going to make another run of it and try to keep this family of employees together because they’ve worked so hard to build this into the company that it is.”

AZUA, Dominican Republic —  It was a busy Saturday morning at Marcia González’s church. A bishop was visiting, and normally she would have been there helping with logistics, but on this day she was teaching sex education at a local school.

“I coordinate activities at the church and my husband is a deacon,” González said. “The bishop comes once a year and children are being confirmed, but I am here because this is important for my community.”

For 40 years, González and her husband have pushed for broader sex education in the Dominican Republic, one of four Latin American nations that criminalizes abortion without exceptions. Women face up to two years in prison for having an abortion; penalties for doctors or midwives range from five to 20 years.

With a Bible on its flag, the Caribbean country has a powerful lobby of Catholics and evangelicals who are united against decriminalizing abortion.

President Luis Abinader committed to the decriminalization of abortion as a candidate in 2020, but his government hasn’t acted on that pledge. For now, it depends on whether he is reelected in May.

To help girls prevent unplanned pregnancies in this context, González and other activists have developed “teenage clubs,” where adolescents learn about sexual and reproductive rights, self-esteem, gender violence, finances and other topics. The goal is to empower future generations of Dominican women.

Outside the clubs, sex education is often insufficient, according to activists. Close to 30% of adolescents don’t have access to contraception. High poverty levels increase the risks of facing an unwanted pregnancy.

For the teenagers she mentors, González’s concerns also go beyond the impossibility of terminating a pregnancy.

According to activists, poverty forces some Dominican mothers to marry their 14 or 15-year-old daughters to men up to 50 years older. Nearly 7 out of 10 women suffer from gender violence such as incest, and families often remain silent regarding sexual abuse.

For every 1,000 adolescents between 15 and 19, 42 became mothers in 2023, according to the United Nations Population Fund. And until 2019, when UNICEF published its latest report on child marriage, more than a third of Dominican women married or entered a free union before turning 18.

Dominican laws have prohibited child marriage since 2021, but community leaders say that such unions are still common because the practice has been normalized and few people are aware of the statute.

“In my 14-year-old granddaughter’s class, two of her younger friends are already married,” González said. “Many mothers give the responsibility of their younger children to their older daughters so, instead of taking care of little boys, they run away with a husband.”

Activists hope education can help prevent girls from facing this situation.

“There are myths that people tell you when you have your period,” said Gabriela Díaz, 16, during a recent encounter organized by the Women’s Equality Center. “They say that we are dirty or we have dirty blood, but that is false. We are helping our body to clean itself and improve its functions.”

Díaz calls González “godmother,” a term applied by Plan International to community leaders who implement the programs of this UK-based organization, which promotes children’s rights.

According to its own data, San Cristóbal and Azua, where González lives, are the Dominican cities with the highest rates of teenage pregnancy and child marriage.

To address this, its clubs accept girls between 13 and 17. Each group meets two hours per week, welcomes up to 25 participants and is led by volunteers like González.

In San Cristobal, also in southern Dominican Republic, the National Confederation of Rural Women (CONAMUCA) sponsors teenage clubs of its own.

“CONAMUCA was born to fight for land ownership, but the landscape has changed, and we have integrated new issues, such as food sovereignty, agrarian reform, and sexual and reproductive rights,” said Lidia Ferrer, one of its leaders.

Its clubs gather 1,600 girls in 60 communities, Ferrer said. The topics they study vary from region to region, but among the recurring ones are adolescent pregnancy, early unions and feminicide.

“The starting point is our own reality,” said Kathy Cabrera, who joined CONAMUCA clubs at age 9 and two decades later takes new generations under her wing. “It’s how we live and suffer.”

Migration is increasingly noticeable in rural areas, Cabrera said. Women are forced to walk for miles to attend school or find water, and health services fail in guaranteeing their sexual and reproductive rights.

“We have a government that tells you ‘Don’t have an abortion’ but does not provide the necessary contraception to avoid it.”

She has witnessed how 13-year-old girls bear the children of 65-year-old men while neither families nor authorities seem to be concerned. On other occasions, she said, parents “give away” their daughters because they cannot support them or because they discover that they are no longer virgins.

“It’s not regarded as sexual abuse because, if my grandmother got pregnant and married at an early age, and my great-grandmother too and my mother too, then it means I should too,” Cabrera said.

In southern Dominican communities, most girls can relate to this, or know someone who does.

“My sister got pregnant at 16, and that was very disturbing,” said 14-year-old Laura Pérez. “She got together with a person much older than her, and they have a baby. I don’t think that was right.”

The clubs’ dynamics change as needed to create safe and loving environments for girls to share what they feel. Some sessions kick off with relaxation exercises and others with games.

Some girls speak proudly of what they have learned. One of them mentioned she confronted her father when he said she shouldn’t cut any lemons from a tree while menstruating. Another said that her friends always go to the bathroom in groups, to avoid safety risks. They all regard their godmothers as mentors who have their backs.

“They call me to confide everything,” González said. “I am happy because, in my group, no girl has become pregnant.”

Many girls from teenage clubs have dreams they want to follow. Francesca Montero, 16, would like to become a pediatrician. Perla Infante, 15, a psychologist. Lomelí Arias, 18, a nurse.

“I want to be a soldier!” shouted Laura Pérez, the 14-year-old who wants to be careful not to following her sister’s footsteps.

“I was undecided, but when I entered CONAMUCA I knew I wanted to become a soldier. In here we see all these women who give you strength, who are like you, but as a guide,” Pérez said. “It’s like a child seeing an older person and thinking: ‘When I grow up, I want to be like that.'”

los angeles — Data gathered by NASA’s Perseverance rover have confirmed the existence of ancient lake sediments deposited by water that once filled a giant basin on Mars called Jezero Crater, according to a study published Friday.

The findings from ground-penetrating radar observations conducted by the robotic rover substantiate previous orbital imagery and other data leading scientists to theorize that portions of Mars were once covered in water and may have harbored microbial life.

The research, led by teams from the University of California at Los Angeles  and the University of Oslo, was published in the journal Science Advances.

It was based on subsurface scans taken by the car-sized, six-wheeled rover as it made its way across the Martian surface from the crater floor onto an adjacent expanse of braided, sedimentary-like features resembling, from orbit, the river deltas found on Earth.

Soundings from the rover’s RIMFAX radar instrument allow scientists to peer underground to get a cross-sectional view of rock layers 65 feet (20 meters) deep, “almost like looking at a road cut,” said UCLA planetary scientist David Paige, the first author of the paper.

Those layers provide unmistakable evidence that soil sediments carried by water were deposited at Jezero Crater and its delta from a river that fed it, just as they are in lakes on Earth. The findings reinforced what previous studies have long suggested — that cold, arid, lifeless Mars was once warm, wet and perhaps habitable.

Scientists look forward to an up-close examination of Jezero’s sediments — thought to have formed some 3 billion years ago — in samples collected by Perseverance for future transport to Earth.

In the meantime, the latest study is welcome validation that scientists undertook their geobiological Mars endeavor at the right place on the planet after all.

Remote analysis of early core samples drilled by Perseverance at four sites close to where it landed in February 2021 surprised researchers by revealing rock that was volcanic in nature, rather than sedimentary as had been expected.

The two studies are not contradictory. Even the volcanic rocks bore signs of alteration through exposure to water, and scientists who published those findings in August 2022 reasoned then that sedimentary deposits may have eroded away.

Indeed, the RIMFAX radar readings reported on Friday found signs of erosion before and after the formation of sedimentary layers identified at the crater’s western edge, evidence of a complex geological history there, Paige said.

“There were volcanic rocks that we landed on,” Paige said. “The real news here is that now we’ve driven onto the delta and now we’re seeing evidence of these lake sediments, which is one of the main reasons we came to this location. So that’s a happy story in that respect.”

NAIROBI, Kenya — Researchers say a rhinoceros was impregnated through embryo transfer in the first successful use of a method that they say might later make it possible to save the nearly extinct northern white rhino subspecies. 

The experiment was conducted with the less endangered southern white rhino subspecies. Researchers created an embryo in a lab from an egg and sperm collected from rhinos and transferred it into a southern white rhino surrogate mother at the Ol-Pejeta Conservancy in Kenya. 

“The successful embryo transfer and pregnancy are a proof of concept and allow [researchers] to now safely move to the transfer of northern white rhino embryos — a cornerstone in the mission to save the northern white rhino from extinction,” the group said in a statement Wednesday. 

However, the team learned of the pregnancy only after the surrogate mother died of a bacterial infection in November 2023. The rhino was infected when spores from the clostridium strain were released from the soil by floodwater, and the embryo was discovered during a post-mortem examination. 

Still, the scientists were optimistic about their finding, though some conservationists are skeptical that the breakthrough has come in time to save the northern white rhino. 

“Now we have the clear evidence that an embryo that is frozen, thawed, produced in a test tube can produce new life, and that is what we want for the northern white rhino,” said Thomas Hildebrandt, the lead researcher and head of the Department of Reproduction at BioRescue. 

Roughly 20,000 southern white rhinos remain in Africa. That subspecies and an additional species, the black rhino, are bouncing back from significant reduction in their populations because of poaching for their horns. 

However, the northern white rhinoceros subspecies has only two known members left in the world. 

Najin, a 34-year-old, and her 23-year-old offspring, Fatu, are both incapable of natural reproduction, according to the Ol-Pejeta Conservancy where they live. 

The last male white rhino, Sudan, was 45 when he was euthanized in 2018 because of age-related complications. He was Najin’s sire. 

Scientists stored his semen and that of four other dead rhinos, hoping to use them in in vitro fertilization with eggs harvested from female northern white rhinos to produce embryos that eventually will be carried by southern white rhino surrogate mothers. 

Some conservation groups have argued that it is probably too late to save the northern white rhino with in vitro fertilization, as the species’ natural habitat in Chad, Sudan, Uganda, Congo and Central African Republic has been ravaged by human conflict. 

Skeptics say the efforts should focus on other critically endangered species with a better chance at survival. 

“News of the first successful embryo transfer in a rhino is an exciting step, however it sadly comes too late to re-create a viable population of northern white rhinos,” said Dr. Jo Shaw, chief executive officer of Save the Rhino International. 

Shaw said her group’s focus remains on addressing the two main threats to the five species of rhino around the world — poaching of rhinos for their horns and their loss of habitat to development. 

“Our best hope remains to work with the range of partners involved to give rhinos the space and security they need to thrive naturally,” she said. 

Her group said it continues to encourage natural breeding to boost numbers. It cited the example of the Sumatran rhino, of which there are fewer than 80 left. Last year, two calves were born through natural reproduction, the group said.

Windhoek, Namibia — Namibian President Hage Geingob is set to undergo medical treatment in the United States after an exam found the possible return of cancerous cells in his body, according to a news release from his office Wednesday.

Having been diagnosed, treated and cleared of prostate cancer, Geingob was again found to have cancerous cells after undergoing colonoscopy, gastroscopy and biopsy procedures earlier this month.

The CEO of the Cancer Association of Namibia, Rolf Hansen, told VOA the president has been open about his cancer diagnosis in the past. He said early detection and treatment played a big role in Geingob’s past treatment and recovery.

“The scope that was done indicates that there might be cancerous cells in the soft tissue, perhaps the gut, the stomach, something like this,” Hansen said. “But until there is a formal prognosis by a doctor that has been publicly released, it’s all speculation.”

Political analyst James Makuwa said Namibians would like to know more about what the latest diagnosis means.

“What are the reasons and motives of the president’s office sharing a diagnosis which has no prognosis?” Makuwa asked. “They are basically putting the country in a state of panic … because you are telling us the person’s diagnosis, but we have no clue what condition he’s in, how he is doing, what is going to happen to him. We have no clue.”

According to the statement issued by the president’s office, Geingob accepted an offer from scientists and doctors in Los Angeles to undergo a novel therapy for the cancerous cells.

Dr. Elizabeth Kamati lauded Geingob’s openness in a country where men are known not to take their health seriously until too late.

“We applaud the president for being very open to us,” she said. “He can encourage other men who are also going through the same disease of cancer, which is somehow taboo in our society, to come out and tell them a diagnosis with cancer is not a death sentence.”

The president has come under harsh criticism in the past for seeking medical treatment abroad. However, Namibian doctors acknowledge that cancer treatments are relatively specialized and that the country does not have the equipment and medical expertise to treat the disease effectively.

Montreal — A 10-year global study of positive doping tests by children and young teenagers showed most were tied to Russia, India and China, and in sports like weightlifting, athletics and cycling, the World Anti-Doping Agency said Wednesday.

Diuretics, stimulants and anabolic steroids were the most commonly found substances in more than 1,500 positive tests involving more than 1,400 minors since 2012.

The youngest athlete tested was 8 years old, and the youngest sanctioned in a doping case was a 12-year-old, WADA said in the Operation Refuge study.

“Operation Refuge reports in heartbreaking detail the deep trauma and isolation child athletes experience following a positive test and a doping sanction,” the chair of WADA’s athlete council, Ryan Pini, said in a statement.

It cited the testimony of a female minor “who recalled the extreme pressure she and other female athletes felt from the male coaches to keep their weight down,” the report said. “This pressure included an impossible expectation to slow down the effects of puberty, because puberty would supposedly negatively impact their ability to compete.”

WADA said its intelligence and investigations unit analyzed testing data of samples collected from minors since 2012. The investigators also received 58 alerts since 2018 on a confidential hotline that implicated minors in doping.

“Analysis of those disclosures revealed that the majority had originated from Russia and India, and that the most reported sports, globally, were aquatics and athletics,” the agency said.

In cases that reached a sanction, the most commonly found doping substance was the diuretic furosemide in Russia, the anabolic steroid stanozolol in India and clenbuterol in China, the report said.

In weightlifting cases, the most common substance was stanozolol. In track and field, it was the endurance boosting hormone EPO. And in cycling, it was meldonium, WADA said. Meldonium is the heart medication most widely known for the doping case of Russian tennis star Maria Sharapova.

WADA said about 80% of positive tests led to sanctions and others were for substances allowed for therapeutic use. Those included a stimulant for treating ADHD (Attention Deficit Hyperactivity Disorder).

Some evidence suggested systematic doping, including multiple minors testing positive for the same substance in samples taken on the same day.

WADA highlighted a 2012 case of four boxers in Romania testing positive for furosemide; three track and field athletes in China testing positive for stanozolol in 2021; two Belarusian skaters testing positive for furosemide in 2022; and two Kazakh weightlifters testing positive for ostarine last year.

“Operation Refuge places a difficult but important issue into the spotlight,” said WADA director of intelligence and investigations Günter Younger. “We are working towards ensuring that the experiences of those interviewed during this operation do not continue to repeat themselves.”

Harare, Zimbabwe — Zimbabwean health authorities — battling a cholera outbreak that has infected about 20,000 people and killed more than 370 — say they hope donated vaccines will ease the spread of waterborne disease now affecting 60 of the country’s 64 districts.  

 

Zimbabwean Health Minister Douglas Mombeshora told reporters in Harare on Wednesday that the country had recorded 20,121 suspected cholera cases and 376 deaths — six of them since Tuesday. He said the World Health Organization and the United Nations Children’s Fund had secured 2.3 million cholera vaccine doses for the country, with nearly 900,000 of them to be administered next week.

 

“The vaccination campaign is expected to start from the 29th of January in [a] phased approach to the hot spots,” he said. “This is because the doses are not enough to cover the whole country. And then roll on to the other affected districts as we receive more vaccines. The challenge is that there is a shortage of vaccine in the world because cholera is not in Zimbabwe alone. So, all other countries that have reported cholera are also getting the same vaccine from the same source. So, it’s now controlled by the WHO. Otherwise only the rich countries will wipe out the vaccines before others get them.”    

 

Mombeshora said 37 African countries had confirmed cases of cholera. The WHO’s Africa office did not confirm the number Wednesday.

In a statement to VOA, Dr. Paul Ngwakum, regional health adviser for UNICEF in eastern and southern Africa, said the cholera outbreak “remains a serious public health concern and continues to impact children’s lives in the region. An unprecedented surge in cholera cases is being recorded in the region due to many factors, including extreme climatic events such as droughts, cyclones and flooding … With porous borders and high population movements, cholera is spreading fast.”

 

Mombeshora is urging Zimbabweans to accept the cholera vaccine.

 

“This is not a new vaccine and it has been used all over the world,” he said. “The only reason why we do not have it enough is because it is only manufactured on demand. Therefore, it’s the same vaccine and it’s very, very safe. We did not receive an adverse report in our past use of it. I have had a cholera vaccine before, years ago, nothing to worry about.”  

 

Dr. Prosper Chonzi, Harare’s director of health services, says now that there is vaccine, people must not ease up on hygienic practices. Chonzi said he was not happy that Harare is still full of vendors selling uninspected fruits and vegetables.

“I think the general economy is playing against us,” he said. “We have been doing these hide-and-seek games, chase after vendors, it has not been working. At least if we clean up for now, then we come up with medium- to long-term plans to maintain the clean environment that is there. As the director of health, I am not happy with the vending situation in the city. It is playing against what we want to achieve as we try to contain the outbreak. If you buy food from uninspected premises, the chances of you contracting not only cholera, but typhoid, dysentery and other diarrhea, are very high.”

 

Zimbabwe’s moribund economy is forcing citizens to venture into vending as a source of income as jobs are hard to come by, with some estimates putting unemployment at about 85%. Experts say that is making the fight against a cholera outbreak difficult with the country recording 1,000 new cases every week since the beginning of the year, according to the United Nations.

ALBUQUERQUE, NEW MEXICO — A federal judge is being asked to issue a stop-work order on a $10 billion transmission line being built through a remote southeastern Arizona valley to carry wind-generated electricity to customers as far away as California. 

A 32-page lawsuit filed on January 17 in U.S. District Court in Tucson, Arizona, accuses the U.S. Interior Department and Bureau of Land Management of refusing for nearly 15 years to recognize “overwhelming evidence of the cultural significance” of the remote San Pedro Valley to Native American tribes, including the Tohono O’odham, Hopi, Zuni and San Carlos Apache Tribe. 

The suit was filed shortly after Pattern Energy received approval to transmit electricity generated by its SunZia wind farm in central New Mexico through the San Pedro Valley east of Tucson and north of Interstate 10. 

The lawsuit calls the valley “one of the most intact, prehistoric and historical … landscapes in southern Arizona” and asks the court to issue restraining orders or permanent injunctions to halt construction. 

“The San Pedro Valley will be irreparably harmed if construction proceeds,” it says. 

Government representatives declined to comment Tuesday on the pending litigation. They are expected to respond in court. The project has been touted as the biggest U.S. electricity infrastructure undertaking since the Hoover Dam. 

Pattern Energy officials said Tuesday that the time has passed to reconsider the route, which was approved in 2015 following a review process. 

“It is unfortunate and regrettable that after a lengthy consultation process, where certain parties did not participate repeatedly since 2009, this is the path chosen at this late stage,” Pattern Energy spokesperson Matt Dallas said in an email. 

Plaintiffs in the lawsuit are the Tohono O’odham Nation, the San Carlos Apache Tribe and the nonprofit organizations Center for Biological Diversity and Archaeology Southwest. 

“The case for protecting this landscape is clear,” Archaeology Southwest said in a statement that calls the San Pedro Arizona’s last free-flowing river and the valley the embodiment of a “unique and timely story of social and ecological sustainability across more than 12,000 years of cultural and environmental change.” 

The valley represents an 80-kilometer (50-mile) stretch of the planned 885-kilometer (550-mile) conduit expected to carry electricity from new wind farms in central New Mexico to existing transmission lines in Arizona to serve populated areas as far away as California. The project has been called an important part of President Joe Biden’s goal for a carbon pollution-free power sector by 2035. 

Work started in September in New Mexico after negotiations that spanned years and resulted in approval from the Bureau of Land Management, the federal agency with authority over vast parts of the U.S. West. 

The route in New Mexico was modified after the U.S. Defense Department raised concerns about the effects of high-voltage lines on radar systems and military training operations. 

Work halted briefly in November amid pleas by tribes to review environmental approvals for the San Pedro Valley and resumed weeks later in what Tohono O’odham Chairman Verlon M. Jose characterized as “a punch to the gut.” 

SunZia expects the transmission line to begin commercial service in 2026, carrying more than 3,500 megawatts of wind power to 3 million people. Project officials say they conducted surveys and worked with tribes over the years to identify cultural resources in the area. 

A photo included in the court filing shows an aerial view in November of ridgetop access roads and tower sites being built west of the San Pedro River near Redrock Canyon. Tribal officials and environmentalists say the region is otherwise relatively untouched. 

The transmission line also is being challenged before the Arizona Court of Appeals. The court is being asked to consider whether state regulatory officials there properly considered the benefits and consequences of the project.

washington — Scientists have mapped the largest coral reef deep in the ocean, stretching hundreds of miles off the U.S. Atlantic Coast. 

While researchers have known since the 1960s that some coral were present off the Atlantic, the reef’s size remained a mystery until new underwater mapping technology made it possible to construct 3D images of the ocean floor. 

The largest yet known deep coral reef “has been right under our noses, waiting to be discovered,” said Derek Sowers, an oceanographer at the nonprofit Ocean Exploration Trust. 

Sowers and other scientists, including several at the National Oceanic and Atmospheric Administration, recently published maps of the reef in the journal Geomatics. 

The reef extends for about 310 miles (499 kilometers) from Florida to South Carolina and at some points reaches 68 miles (109 kilometers) wide. The total area is nearly three times the size of Yellowstone National Park. 

“It’s eye-opening — it’s breathtaking in scale,” said Stuart Sandin, a marine biologist at the Scripps Institution of Oceanography, who was not involved in the study. 

The reef was found at depths ranging from 655 feet to 3,280 feet (200 meters to 1,000 meters), where sunlight doesn’t penetrate. Unlike tropical coral reefs, where photosynthesis is important for growth, coral this far down must filter food particles out of the water for energy. 

Deep coral reefs provide habitat for sharks, swordfish, sea stars, octopus, shrimp and many other kinds of fish, the scientists said. 

Tropical reefs are better known to scientists – and snorkelers – because they’re more accessible. The world’s largest tropical coral reef system, the Great Barrier Reef in Australia, stretches for about 1,430 miles (2,301 kilometers). 

Sowers said it’s possible that larger deep-sea reefs will be discovered in the future since only about 75% of the world’s ocean floor has been mapped in high-resolution. Only 50% of U.S. offshore waters have been mapped. Maps of the ocean floor are created using high-resolution sonar devices carried on ships. 

Deep reefs cover more of the ocean floor than tropical reefs. Both kinds of habitat are susceptible to similar risks, including climate change and disturbance from oil and gas drilling, said Erik Cordes, a marine biologist at Temple University and co-author of the new study.
