Kidney transplants are safe between people with HIV, US study shows 

People with HIV can safely receive donated kidneys from deceased donors with the virus, according to a large study that comes as the U.S. government moves to expand the practice. That could shorten the wait for organs for all, regardless of HIV status.

The new study, published Wednesday in the New England Journal of Medicine, looked at 198 kidney transplants performed across the U.S. Researchers found similar results whether the donated organ came from a person with or without the AIDS virus.

Last month, the Department of Health and Human Services proposed a rule change that would allow these types of kidney and liver transplants outside research studies. A final rule would apply to both living and deceased donors. If approved, it could take effect in the coming year.

Participants in the study were HIV positive, had kidney failure and agreed to receive an organ from either an HIV-positive deceased donor or an HIV-negative deceased donor, whichever kidney became available first.

Similar survival rates

Researchers followed the organ recipients for up to four years. They compared the half who received kidneys from HIV-positive donors to those whose kidneys came from donors without HIV.

Both groups had similarly high rates of overall survival and low rates of organ rejection. Virus levels rose for 13 patients in the HIV donor group and for four in the other group, mostly tied to patients failing to take HIV medications consistently, and in all cases returned to very low or undetectable levels.

“This demonstrates the safety and the fantastic outcomes that we’re seeing from these transplants,” said study co-author Dr. Dorry Segev of NYU Langone Health.

In 2010, surgeons in South Africa provided the first evidence that using HIV-positive donor organs was safe in people with HIV. But the practice wasn’t allowed in the United States until 2013 when the government lifted a ban and allowed research studies, at the urging of Segev. At first, the studies were with deceased donors. Then in 2019, Segev and others at Johns Hopkins University in Baltimore performed the world’s first kidney transplant from a living donor with HIV to an HIV-positive recipient.

All told, 500 transplants of kidneys and livers from HIV-positive donors have been done in the U.S.

‘A win-win’

People with HIV have been actively discouraged from signing up to be organ donors by stigma and outdated state laws and policies criminalizing organ donation for people with HIV, said Carrie Foote, a sociology professor at Indiana University in Indianapolis.

“Not only can we help those of us living with this disease, but we free up more organs in the entire organ pool so that those who don’t have HIV can get an organ faster,” said Foote, who is HIV positive and a registered organ donor. “It’s a win-win for everyone.”

More than 90,000 people are on the waiting list for kidney transplants, according to the U.S. Organ Procurement and Transplantation Network. In 2022, more than 4,000 people died waiting for kidneys.

In an editorial in the journal, Dr. Elmi Muller of Stellenbosch University in South Africa predicted the new study will have “far-reaching effects in many countries that do not perform transplantations with these organs.”

“Above all, we have taken yet another step toward fairness and equality for persons living with HIV,” wrote Muller, who pioneered the practice.

Polio crisis deepens as Pakistan reports new cases

ISLAMABAD — Pakistan said Saturday that two children in its southern Sindh province had been paralyzed by poliovirus, bringing the total number of cases nationwide to 39 for the year since March, when officials confirmed the first case.

The South Asian nation of around 240 million people reported six cases of paralytic poliovirus infections in 2023, following a period of more than a year without any documented cases, only to see the numbers rise again.

“Genetic sequencing of the cases is under way,” said a Pakistan polio eradication program statement Saturday while reporting the two new infections in Sindh. “The intense virus transmission and increase in polio cases are indicative of the harm that children suffer when they miss opportunities for vaccination.”

Pakistan and neighboring Afghanistan, with at least 20 cases this year, are the only two countries where the crippling disease is still endemic.

Pakistani officials are preparing to launch a nationwide vaccination campaign on October 28 to immunize more than 45 million children under 5 against the paralytic disease.

“It is critical for parents to open their doors to vaccinators during this drive and ensure that all children in their care receive two drops of the crucial oral polio vaccine to keep them protected from the devastating effects of polio,” the program emphasized in its Saturday statement.

Pakistan’s southwestern Balochistan province, which sits on the Afghan border, has reported 20 polio cases in 2024, while Sindh has detected 12 cases.

The Khyber Pakhtunkhwa province bordering Afghanistan has documented five paralytic poliovirus cases. Pakistan’s most populous Punjab province and the national capital, Islamabad, reported one case each.

The resurgence of poliovirus in Pakistan is blamed on boycotts of vaccination drives by parents in rural areas who allege the initiatives are a Western plot to sterilize Muslim children.

Anti-state militants in violence-hit districts bordering Afghanistan occasionally attack vaccinators and their police escorts, suspecting them of spying for the government. The violence has claimed the lives of dozens of security forces and vaccinators.

An independent monitoring board of the Global Polio Eradication Initiative noted in a report last month that more than 420,000 Pakistani children could not be inoculated in anti-polio campaigns in 2024.

The board reported more than 200 boycotts of the polio vaccination campaign in Khyber Pakhtunkhwa last year. “It is disturbing to realize that violence, insecurity, and boycotts are still as prevalent in Khyber Pakhtunkhwa as they were in 2023,” the report said.

It highlighted that residents in several impoverished districts of Pakistan also demanded electricity, gas supply, and road construction in return for getting their children vaccinated.

A representative for Pakistan’s Ministry of Health told a World Health Organization meeting in Doha, Qatar, earlier this week that polio eradication is the country’s “top priority,” and efforts have been intensified to halt virus transmission.

“Despite recent resurgence, a unified plan with provinces aims to stop polio transmission by 2025,” Safi Malik stated. “We’re focusing on quality campaigns, digital tracking of missed areas, and a strong Pakistan-Afghanistan collaboration for cross-border vaccinations,” he said. 

Nigeria rolls out long-anticipated malaria vaccine

ABUJA, NIGERIA — Nigeria officially launched its malaria vaccination campaign this week to protect millions of children from the deadly disease, focusing heavily on high-risk states.

The first 846,000 doses of the R21 malaria vaccine arrived in Abuja, Nigeria, on Thursday, marking a milestone in efforts to eliminate malaria. According to the World Health Organization, the country accounts for about 27% of global malaria cases. In 2022, it recorded nearly 67 million infections and nearly 200,000 deaths, about 80% of the deaths occurring in children under age 5.

Dr. Muyi Aina, head of the National Primary Health Care Development Agency, said the initial rollout prioritizes high-risk regions.

“We expect another 140,000 or so to make a million doses in this first batch,” Aina said. “Every child, every person that is vaccinated, needs to get two doses. So, we know that that’s a limited number of people. So, we have prioritized the highest-burden locations in the country, Kebbi and Bayelsa.”

The government is covering part of the vaccine costs, with global vaccine group Gavi and international partners funding the rest.

Health Minister Muhammad Pate stressed that the vaccine will be administered to recipients at no charge.

“These vaccines are free for [the] population, but they cost resources,” he said.

Not everyone would be able to afford the vaccines, Pate said.

“The children of the poor in rural areas are the ones that may not be able to access them,” he said. “That’s why we’ve prioritized public financing in that regard, and we thank our partners for contributing toward it.”

Nigeria has improved vaccine logistics for hard-to-reach regions.

UNICEF’s chief of health in Nigeria, Dr. Eduardo Celades, expressed confidence in the country’s distribution capacity.

“Transportation and storage [are] a key issue,” he said. “How [can you] ensure that the cold chain has the integrity needed to keep safe the vaccines and to keep them effective? But we are confident that we know that we have the capacities.”

Malaria remains a complex challenge, requiring a mix of strategies such as mosquito control, better health care access and vaccine monitoring.

Malaria elimination strategic adviser Olugbenga Mokuolu said the vaccine complements traditional tools such as bed nets and treatments, offering children added protection.

“We know that no single tool offers 100% of the solution,” Mokuolu said. “That’s why we still talk about the combination of tools. But having the vaccine layering on it is very significant. … With the deployment of this vaccine, we will be conducting … an effectiveness study in order to note the rate of reoccurrence while on the vaccine.”

The WHO approved the RTS,S and R21 vaccines, with R21 showing 77% efficacy in trials. Other African countries, including Uganda and Burkina Faso, have begun vaccine distribution, reflecting the continent’s push to combat malaria.

Experts say the success of the malaria rollout depends on sustained engagement with local leaders and caregivers to ensure children complete their doses.

Aging farmers face extreme temperatures as they struggle to maintain Japan’s rice crop

KAMIMOMI, Japan — In the remote village of Kamimomi in Japan’s western Okayama prefecture, a small group of rice farmers began their most recent harvest in sweltering heat, two weeks sooner than usual.

The prefecture is called “the Land of Sunshine” because of its pleasant climate, but farmers working among the paddy fields and ancient rice terraces say that climate change is hurting the harvest of rice, long a cornerstone of Japan’s diet.

“Last year, an exceptional heat wave took the water out of the rice, which became small and thin,” rice farmer Joji Terasaka said. “So I am worried about that this year because it will be just as hot.”

This year Japan experienced its hottest July on record, with temperatures reaching 2.16 Celsius higher than average, according to the Japan Meteorological Agency. The globe has seen a 1.2 C rise in average temperature since preindustrial times, and scientists agree that warming needs to be capped at 1.5 C to stave off the worst effects of climate change. That includes even more powerful heat, storms and irreversible ice melt.

Last year, Japan recorded a poor rice harvest nationwide because of exceptionally hot weather. Ministry data showed the country’s private-sector rice inventory fell to 1.56 million tons in June, the lowest level since records began in 1999. Last year was the hottest on record globally, though it’s feared that this year may top it.

The drop in harvest in Japan was partly to blame for this year’s widespread summer rice shortage, according to officials. There were empty shelves in supermarkets, and some retailers are still enforcing purchase limits of one rice bag per customer.

“Perhaps people think that an increase of one degree Celsius in average temperature isn’t much. But it’s quite a big change for plants and crops,” says Yuji Masutomi, a researcher at the National Institute for Environmental Studies in Tsukuba, north of Tokyo.

Masutomi said the rising temperatures not only influence the growth cycle and yield of rice, but also hurt the quality of the grain.

When temperatures rise above 27 C, the buildup of starch inside rice grains is reduced. That causes the crop to take on a chalky appearance, and its value is reduced.

At least a fifth of rice farms have reported a drop in quality from rising temperatures, according to a farming ministry report last year.

“Not only is the appearance not good; people say the taste drops too,” Masutomi said.

For farmers in Kamimomi, there’s another problem with working under exceptional heat. The average age of agricultural workers in Japan is nearly 69, among the oldest in the world, and older people are especially vulnerable to heatstroke.

Toshimi Kaiami led a community project in Kamimomi that involved reviving some of the paddy fields abandoned because of the aging population.

“There are no longer any successors,” says Kaiami. “We are heading toward extinction.”

The community project divides labor among Kamimomi’s farmers. But preparations for the harvest coincided with the hottest months of the year — April to September.

“It takes a half year to produce rice. The heat and the work that we have to endure during that time is really tough,” said rice farmer Mitsumasa Sugimoto, 77.

To deal with climate change, the government is promoting the adoption of heat-resistant rice variants, including Sai no Kizuna, which was developed by a research center in Saitama prefecture, near Tokyo.

Research organizations around the world have worked to produce more resilient strains of essential food like rice while introducing more heat and drought resistant grains like sorghum or millet.

“Last year and this year have been extremely hot, but even in those conditions, Sai no Kizuna maintained a certain level of quality,” said Naoto Ohoka, who manages rice breeding at Saitama’s Agricultural Technology Research Center.

“Its other characteristic is that it is very delicious.”

The center cultivates more than a thousand types of rice strains, and through cross-pollination officials assess and select the best performers to develop new varieties.

Sai no Kizuna was developed in 2012 to better withstand heat, a trait that has become more widely recognized recently as Japan sees hotter summers. The strain also stands up well against typhoon wind and certain pests and diseases.

Researchers want to develop more resilient strains against heat as temperatures are projected to continue rising. Masutomi recommends that variants tolerant of temperatures up to 3 degrees Celsius higher should be introduced across Japan by the 2040s.

But it’s a long process. It can take up to 10 years to develop a new variant. Once it’s approved for the market, farmers must then be convinced to switch to the new strain.

The most widely grown variety is Koshihikari, which is less heat resistant. Even so, older farmers have shown a reluctance to switch to other varieties. Farming ministry data show that only around 15% of Japanese paddy fields have adopted heat resistance variants.

Pressure grows for nations to deliver on promised biodiversity targets at UN conference

Two years after reaching a historic biodiversity agreement, countries will gather next week to determine whether they are making progress on efforts to save Earth’s plant and animal life.

The agreement signed by 196 countries at the United Nations Biodiversity Conference calls for protecting 30% of land and water by 2030, known as 30 by 30. When the agreement was signed, 17% of terrestrial and 10% of marine areas were protected — which hasn’t changed significantly.

At the conference known as COP16, countries next will report on progress made toward the goals, and governments are expected to agree on mechanisms to assure the implementation of them, according to a European Parliament report.

The two-week meeting in Cali, Colombia, will also focus on efforts to raise hundreds of billions of dollars to protect nature by 2030 — with the payment of $20 billion for developing countries due next year. Twenty-three targets will be discussed including cutting food waste and preventing the introduction of invasive species.

Signs of progress hard to find

The nearly 200 countries are supposed to submit national plans ahead of the conference showing actions they are taking to meet the 30 by 30 goals. But as of this week, around 46% of countries have submitted targets and less than 15% submitted plans for reaching them. Australia has yet to submit its targets while India has not submitted a national plan. Brazil, which includes much of the Amazon rainforest, hasn’t submitted targets or a plan.

The United States, which is not party to the biodiversity convention, is not required to submit any plans. But the Biden administration has committed to protecting a third of American land and waters by 2030.

Some countries are expected to use the conference to unveil plans for creating or expanding protected areas and for how they’ll spend biodiversity funding. Canada, for example, has committed to spending $800 million on four Indigenous-led projects.

Conservation groups are concerned that more countries have not yet detailed their biodiversity goals and how to achieve them.

Bernadette Fischler Hooper, head of global advocacy for WWF International, called the commitments so far “disappointing.” WWF, which is tracking the progress, also found some plans lack actions to halt biodiversity loss, funding to support efforts and sufficient buy-in from across government.

“This is really, really getting close,” Hooper said. “There are some countries who can easily afford to update (their plans). There’s no reason why they didn’t do it … and there are countries that didn’t get the support they needed.”

Of the 91 countries that submitted targets, the convention’s secretariat found more than half had targets of protecting and conserving at least 30% of their terrestrial area and about a quarter had targets for 5% to 30%. For marine and coastal areas, more than one-third had a national target of 30% or more, and another third had targets between 5% and 30%.

But Astrid Schomaker, executive secretary of the Convention on Biological Diversity, said the small number of countries submitting plans isn’t surprising since governments first had to come up with targets and then develop action plans.

“These are complex processes that are meant to be a whole of government,” she said of the plans that require coordination and buy-in from ministries, business leaders and community stakeholders, as well as raising money. “That’s not happening overnight.”

Achieving these targets is especially critical to migratory species, more than 40% which a U.N. report found are declining.

“Birds do not recognize boundaries of a protected area and move according to their feeding and roosting needs,” said Jennifer George, who leads the Seoul-based East Asian-Australasian Flyway Partnership, a nonprofit focused on birds migrating between East Asia, Australia and New Zealand.

Funding crunch

Much like the U.N. climate talks, a big topic of debate at the biodiversity conference will be financing.

Poor countries pushed to include language requiring that $200 billion a year be raised by 2030 for biodiversity from a range of sources to fund the target-specific projects. Rich countries committed to providing developing countries $20 billion starting next year and gradually scaling that up to $30 billion by 2030.

The Organization for Economic Cooperation and Development reported in September that development finance for biodiversity more than doubled from 2015 to 2022. But when it comes to funding for this agreement, the world was still 23% short of the $20 billion goal.

Advocates said money will be critical since much of the biodiversity that needs protecting is in developing countries like those in Africa.

“There has been progress. Is there enough progress? No,” said Susan Lieberman, the vice president of international policy at Wildlife Conservation Society. “Some countries are taking it seriously and other countries are saying, ‘Oh we want to do this, but where’s the money?'”

More than 30 by 30

In addition to top-tier biodiversity targets, the conference will discuss a goal in the agreement to halt human-induced extinction of threatened species and, by 2050, to reduce extinction rates tenfold. The goal also calls for increasing the “abundance of native wild species” to healthy levels.

But conservationists say the goals lack specifics and hope details can be agreed upon at the meeting.

“Many of these other targets need to be nailed down and quantified, like stopping species extinctions,” said Duke University ecologist Stuart Pimm. “At the moment, they are terribly vague.”

Countries plan to showcase the role biodiversity plays in achieving climate mitigation goals and in health, especially preventing future pandemics.

The meeting will also consider adoption of a global mechanism for sharing of benefits from digital data from genetic material derived from plants, animals, bacteria and viruses. The materials are often used to developed commercial products like drugs — and the hope is that an agreement will ensure profits are shared equitably. 

Dense breasts can make it harder to spot cancer on a mammogram

When a woman has a mammogram, the most important finding is whether there’s any sign of breast cancer.

The second most important finding is whether her breasts are dense.

Since early September, a new U.S. rule requires mammography centers to inform women about their breast density — information that isn’t entirely new for some women because many states already had similar requirements.

Here’s what to know about why breast density is important.

Are dense breasts bad?

No, dense breasts are not bad. In fact, they’re quite normal. About 40% of women ages 40 and older have dense breasts.

Women of all sizes can have dense breasts. It has nothing to do with breast firmness. And it only matters in the world of breast cancer screening, said Dr. Ethan Cohen of MD Anderson Cancer Center in Houston.

With the new rule, “there are going to be a lot of questions to a lot of doctors and there’s going to be a lot of Googling, which is OK. But we want to make sure that people don’t panic,” Cohen said.

How is breast density determined?

Doctors who review mammograms have a system for classifying breast density.

There are four categories. The least dense category means the breasts are almost all fatty tissue. The most dense category means the breasts are mostly glandular and fibrous tissue.

Breasts are considered dense in two of the four categories: “heterogeneously dense” or “extremely dense.” The other two categories are considered not dense.

Dr. Brian Dontchos of the Seattle-based Fred Hutchinson Cancer Center said the classification can vary depending on the doctor reading the mammogram “because it’s somewhat subjective.”

Why am I being told I have dense breasts?

Two reasons: For one, dense breasts make it more difficult to see cancer on an X-ray image, which is what a mammogram is.

“The dense tissue looks white on a mammogram and cancer also looks white on a mammogram,” said Dr. Wendie Berg of the University of Pittsburgh School of Medicine and chief scientific adviser to DenseBreast-info.org. “It’s like trying to see a snowball in a blizzard.”

Second, women with dense breast tissue are at a slightly higher risk of developing breast cancer because cancers are more likely to arise in glandular and fibrous tissue.

Reassuringly, women with dense breasts are no more likely to die from breast cancer compared to other women.

What am I supposed to do?

If you find out you have dense breasts, talk to your doctor about your family history of breast cancer and whether you should have additional screening with ultrasound or MRI, said Dr. Georgia Spear of Endeavor Health/NorthShore University Health System in the Chicago area.

Researchers are studying better ways to detect cancer in women with dense breasts. So far, there’s not enough evidence for a broad recommendation for additional screening. The U.S. Preventive Services Task Force called for more research in this area when it updated its breast cancer screening recommendations earlier this year.

Do I still need a mammogram?

Yes, women with dense breasts should get regular mammograms, which is still the gold standard for finding cancer early. Age 40 is when mammograms should start for women, transgender men and nonbinary people at average risk.

“We don’t want to replace the mammogram,” Spear said. “We want to add to it by adding a specific other test.”

Will insurance cover additional screening?

For now, that depends on your insurance, although a bill has been introduced in Congress to require insurers to cover additional screening for women with dense breasts.

Additional screening can be expensive — from $250 to $1,000 out of pocket, so that’s a barrier for many women.

“Every woman should have equal opportunity to have their cancer found early when it’s easily treated,” Berg said. “That’s the bottom line.”

Drone maker DJI sues Pentagon over Chinese military listing

WASHINGTON — China-based DJI sued the U.S. Defense Department on Friday for adding the drone maker to a list of companies allegedly working with Beijing’s military, saying the designation is wrong and has caused the company significant financial harm.

DJI, the world’s largest drone manufacturer that sells more than half of all U.S. commercial drones, asked a U.S. District Judge in Washington to order its removal from the Pentagon list designating it as a “Chinese military company,” saying it “is neither owned nor controlled by the Chinese military.”

Being placed on the list represents a warning to U.S. entities and companies about the national security risks of conducting business with them.

DJI’s lawsuit says because of the Defense Department’s “unlawful and misguided decision” it has “lost business deals, been stigmatized as a national security threat, and been banned from contracting with multiple federal government agencies.”

The company added “U.S. and international customers have terminated existing contracts with DJI and refuse to enter into new ones.”

The Defense Department did not immediately respond to a request for comment.

DJI said on Friday it filed the lawsuit after the Defense Department did not engage with the company over the designation for more than 16 months, saying it “had no alternative other than to seek relief in federal court.”

Amid strained ties between the world’s two biggest economies, the updated list is one of numerous actions Washington has taken in recent years to highlight and restrict Chinese companies that it says may strengthen Beijing’s military.

Many major Chinese firms are on the list, including aviation company AVIC, memory chip maker YMTC, China Mobile 0941.HK, and energy company CNOOC.

In May, lidar manufacturer Hesai Group ZN80y.F filed a suit challenging the Pentagon’s Chinese military designation for the company. On Wednesday, the Pentagon removed Hesai from the list but said it will immediately relist the China-based firm on national security grounds.

DJI is facing growing pressure in the United States.

Earlier this week DJI told Reuters that Customs and Border Protection is stopping imports of some DJI drones from entering the United States, citing the Uyghur Forced Labor Prevention Act.

DJI said no forced labor is involved at any stage of its manufacturing.

U.S. lawmakers have repeatedly raised concerns that DJI drones pose data transmission, surveillance and national security risks, something the company rejects.

Last month, the U.S. House voted to bar new drones from DJI from operating in the U.S. The bill awaits U.S. Senate action. The Commerce Department said last month it is seeking comments on whether to impose restrictions on Chinese drones that would effectively ban them in the U.S. — similar to proposed Chinese vehicle restrictions. 

Namibia hosts workshop on health care access to LGBTQ+ community

WINDHOEK, NAMIBIA — Namibians who are part of the LGBTQ+ community often find it difficult to get decent health care and many report discriminatory practices within the health care system.

For example, when 20-year-old Immanuel Uirab sought contraception at a health facility, the nurse on duty would not assist him.

“I don’t know if it’s the shorts I was wearing or you can generally just tell by looking at me that I am gay,” he said, “but then this particular nurse … came out and she was, like, ‘No, we don’t offer contraceptives for people who practice sodomy. We can’t do that for you. … You can go buy them if you want to use them in your private space, but we … won’t give them to you because our government does not support homosexuality.’”

A recent two-day training workshop facilitated by the group Our Equity Advocacy was aimed at encouraging health care practitioners in Namibia to not discriminate against sexual minorities.

Discrimination in health care services violates the right to health care and the human rights principles of equity, privacy and dignity, said the United Nation’s special rapporteur on the right to health, Dr. Tlaleng Mofokeng.

Mofokeng held a workshop last weekend in Windhoek where she trained health care practitioners and young people about the role of health care in human rights.

There are many opportunities in which health care workers “can take a seat at the table,” she said. “Not just in policymaking, but importantly in advocacy … also in understanding human rights.”

The executive director of Namibia’s Ministry of Health, Ben Nangombe, said that discrimination in health care based on sexual orientation is against the law and that practitioners who refuse health care to patients for any reason can lose their jobs.

“The official position [of the] government on this matter is that the Namibian government provides health care services to all Namibians who need it without any discrimination whatsoever,” he said.

One theme from last weekend’s workshop was the need for nurses to become agents of change and advocates for their patients.

Letlhogonolo Mokgoroane, a legal practitioner and health rights activist from South Africa who co-facilitated the workshop, said members of sexual minority groups in Africa often face intrusive questioning when they seek medical care.

“Let’s say you are going to a hospital or a clinic for a broken arm or a headache, some tummy ache, whatever,” Mokgoroane said. “What often happens is when you are trans or when you are gender nonconforming or when you are a member of the LGBTI community, immediately what happens is that the questions veer away from why you are actually there to really invasive and discriminatory questions, right? ‘I have a headache, why are you asking me about my sex life? … I have a headache, why are you asking me about my genitalia?’”

Mokgoroane said the issue can be addressed by training health care workers to affirm the gender of their patients when they treat them.

However, Mokgoroane expressed worry that the rise of anti-LGBTQ+ laws in Africa will further drive discriminatory practices in the health care system and undermine public health altogether.

Moonlight may hamper views of Orionid meteor shower, debris of Halley’s comet

washington — The Orionids — one of two annual meteor showers from Halley’s comet — peak early Monday. A bright waning moon may make them difficult to spot.

The Orionid meteor shower can be unpredictable. It shines like a fireworks display in some years but is fairly slow in other years.

This highly variable shower may result in anywhere from 20 to 60 visible meteors per hour under ideal viewing conditions, said NASA’s Bill Cooke.

This year’s peak activity happens on a night when a waning moon is 83% full. The shower lasts through November 22.

Here’s what to know about the Orionids and other meteor showers.

What is a meteor shower?

Multiple meteor showers occur annually and don’t require special equipment to see them.

Most meteor showers originate from the debris of comets. The source of the Orionids is Halley’s comet.

When rocks from space enter Earth’s atmosphere, the resistance from the air makes them very hot. This causes the air to glow around them and briefly leaves a fiery tail behind them — the end of a “shooting star.”

The glowing pockets of air around fast-moving space rocks, ranging from the size of a dust particle to a boulder, may be visible in the night sky.

“Halley’s comet does not leave the same numbers of particles behind each year,” making it hard to predict what kind of show viewers will see, said Cooke.

How to view a meteor shower

Meteor showers are usually most visible between midnight and predawn hours.

It’s easier to see shooting stars under dark skies, away from city lights. Meteor showers also appear brightest on cloudless nights when the moon wanes smallest.

And your eyes will better adapt to seeing meteors if you aren’t checking your phone.

“It ruins your night vision,” said Cooke.

When is the next meteor shower?

October has been an active time for celestial sightings including the latest supermoon and the comet Tsuchinshan-Atlas.

The meteor society keeps an updated list of upcoming large meteor showers, including the peak viewing days and moonlight conditions.

The next big one is the Southern Taurid meteor shower, which peaks in early November.

Residents on Kenya’s coast use app to track migratory birds

The Tana River delta on the Kenyan coast includes a vast range of habitats and a remarkably productive ecosystem, says UNESCO. It is also home to many bird species, including some that are nearly threatened. Residents are helping local conservation efforts with an app called eBird. Juma Majanga reports.

Deepfakes featuring deceased terrorists spread radical propaganda

In a year with over 60 national elections worldwide, concerns are high that individuals and entities are using deepfake images and recordings to contribute to the flood of election misinformation. VOA’s Rio Tuasikal reports on some potentially dangerous videos made using generative AI.

US prosecutors see rising threat of AI-generated child sex abuse imagery

U.S. federal prosecutors are stepping up their pursuit of suspects who use artificial intelligence tools to manipulate or create child sex abuse images, as law enforcement fears the technology could spur a flood of illicit material.

The U.S. Justice Department has brought two criminal cases this year against defendants accused of using generative AI systems, which create text or images in response to user prompts, to produce explicit images of children.

“There’s more to come,” said James Silver, the chief of the Justice Department’s Computer Crime and Intellectual Property Section, predicting further similar cases.

“What we’re concerned about is the normalization of this,” Silver said in an interview. “AI makes it easier to generate these kinds of images, and the more that are out there, the more normalized this becomes. That’s something that we really want to stymie and get in front of.”

The rise of generative AI has sparked concerns at the Justice Department that the rapidly advancing technology will be used to carry out cyberattacks, boost the sophistication of cryptocurrency scammers and undermine election security. 

Child sex abuse cases mark some of the first times that prosecutors are trying to apply existing U.S. laws to alleged crimes involving AI, and even successful convictions could face appeals as courts weigh how the new technology may alter the legal landscape around child exploitation. 

Prosecutors and child safety advocates say generative AI systems can allow offenders to morph and sexualize ordinary photos of children and warn that a proliferation of AI-produced material will make it harder for law enforcement to identify and locate real victims of abuse.

The National Center for Missing and Exploited Children, a nonprofit group that collects tips about online child exploitation, receives an average of about 450 reports each month related to generative AI, according to Yiota Souras, the group’s chief legal officer.

That’s a fraction of the average of 3 million monthly reports of overall online child exploitation the group received last year.

Untested ground

Cases involving AI-generated sex abuse imagery are likely to tread new legal ground, particularly when an identifiable child is not depicted.

Silver said in those instances, prosecutors can charge obscenity offenses when child pornography laws do not apply.

Prosecutors indicted Steven Anderegg, a software engineer from Wisconsin, in May on charges including transferring obscene material. Anderegg is accused of using Stable Diffusion, a popular text-to-image AI model, to generate images of young children engaged in sexually explicit conduct and sharing some of those images with a 15-year-old boy, according to court documents.

Anderegg has pleaded not guilty and is seeking to dismiss the charges by arguing that they violate his rights under the U.S. Constitution, court documents show.

He has been released from custody while awaiting trial. His attorney was not available for comment.

Stability AI, the maker of Stable Diffusion, said the case involved a version of the AI model that was released before the company took over the development of Stable Diffusion. The company said it has made investments to prevent “the misuse of AI for the production of harmful content.”

Federal prosecutors also charged a U.S. Army soldier with child pornography offenses in part for allegedly using AI chatbots to morph innocent photos of children he knew to generate violent sexual abuse imagery, court documents show.

The defendant, Seth Herrera, pleaded not guilty and has been ordered held in jail to await trial. Herrera’s lawyer did not respond to a request for comment.

Legal experts said that while sexually explicit depictions of actual children are covered under child pornography laws, the landscape around obscenity and purely AI-generated imagery is less clear. 

The U.S. Supreme Court in 2002 struck down as unconstitutional a federal law that criminalized any depiction, including computer-generated imagery, appearing to show minors engaged in sexual activity. 

“These prosecutions will be hard if the government is relying on the moral repulsiveness alone to carry the day,” said Jane Bambauer, a law professor at the University of Florida who studies AI and its impact on privacy and law enforcement.

Federal prosecutors have secured convictions in recent years against defendants who possessed sexually explicit images of children that also qualified as obscene under the law. 

Advocates are also focusing on preventing AI systems from generating abusive material. 

Two nonprofit advocacy groups, Thorn and All Tech Is Human, secured commitments in April from some of the largest players in AI including Alphabet’s Google, Amazon.com, Facebook and Instagram parent Meta Platforms, OpenAI and Stability AI to avoid training their models on child sex abuse imagery and to monitor their platforms to prevent its creation and spread. 

“I don’t want to paint this as a future problem, because it’s not. It’s happening now,” said Rebecca Portnoff, Thorn’s director of data science.

“As far as whether it’s a future problem that will get completely out of control, I still have hope that we can act in this window of opportunity to prevent that.”

Watchdog: ‘Serious questions’ over Meta’s handling of anti-immigrant posts

Meta’s independent content watchdog said Thursday there were “serious questions” about how the social media giant deals with anti-immigrant content, particularly in Europe. 

The Oversight Board, established by Meta in 2020 and sometimes called its “supreme court,” launched a probe after seeing a “significant number” of appeals over anti-immigrant content. 

The board has chosen two symbolic cases — one from Germany and the other from Poland — to assess whether Meta, which owns Facebook and Instagram, is following human rights law and its own policies on hate speech. 

Helle Thorning-Schmidt, co-chair of the board and a former Danish prime minister, said it was “critical” to get the balance right between free speech and protection of vulnerable groups. 

“The high number of appeals we get on immigration-related content from across the EU tells us there are serious questions to ask about how the company handles issues related to this, including the use of coded speech,” she said in a statement. 

The first piece of content to be assessed by the board was posted in May on a Facebook page claiming to be the official account of Poland’s far-right Confederation party. 

An image depicts Polish Prime Minister Donald Tusk looking through a peephole with a black man approaching him from behind, accompanied by text suggesting his government would allow immigration to surge. 

Meta rejected an appeal from a user to take down the post despite the text including a word considered by some as a racial slur. 

In the other case, an apparently AI-generated image was posted on a German Facebook page showing a blond-haired blue-eyed woman, a German flag and a stop sign. 

The accompanying text likens immigrants to “gang rape specialists.”  

A user complained but Meta decided to not to remove the post.  

“The board selected these cases to address the significant number of appeals, especially from Europe, against content that shares views on immigration in ways that may be harmful towards immigrants,” the watchdog said in a statement. 

The board said it wanted to hear from the public and would spend “the next few weeks” discussing the issue before publishing its decision. 

Decisions by the board, funded by a trust set up by Meta, are not binding, though the company has promised to follow its rulings. 

Colombian ranchers aim to prove beef production can be good for planet

Scientists say beef production takes a heavy toll on the environment. Cattle produce methane, a powerful planet-warming gas, and forests get cut down for pastures. But one farm in northern Colombia hopes to show ranching can have a lighter footprint on the planet. Austin Landis travelled to Montería in northern Colombia for a closer look at what could be a revolution in sustainable cattle ranching.

US Supreme Court declines to pause EPA power plant emissions rule

The U.S. Supreme Court declined on Wednesday to put on hold a new federal rule targeting carbon pollution from coal- and gas-fired power plants at the request of numerous states and industry groups in another major challenge to President Joe Biden’s efforts to combat climate change.

The justices denied emergency requests by West Virginia, Indiana and 25 other states — most of them Republican led — as well as power companies and industry associations, to halt the Environmental Protection Agency rule while litigation continues in a lower court. The regulation, aimed at cutting greenhouse gas emissions that drive climate change, took effect July 8.

The rule would require existing coal and new natural gas-fired plants eventually to reduce emissions including by capturing and storing carbon dioxide.

The EPA’s new rule, issued under the landmark Clean Air Act anti-pollution law, was issued two years after a major ruling by the Supreme Court in 2022 undercut the agency’s power to issue sweeping regulations to force an electricity-generation shift from coal to cleaner energy sources.

The EPA has said efforts to address climate change and its impacts such as extreme weather and rising sea levels must include the power sector because fossil fuel-fired plants make up 25% of overall domestic greenhouse gas emissions.

Notably, the rule mandates that coal plants operating past 2038 and certain new gas plants reduce emissions by 90% by 2032 including by using carbon capture and storage systems that extract carbon dioxide from plant exhaust and sequester it underground.

The EPA has called the technology proven and technically feasible. The rule’s challengers have said it has not been shown effective at the scale predicted by the EPA.

The rule’s requirements are “really a backdoor avenue to forcing coal plants out of existence,” West Virginia, a major coal producer, and other state challengers said in a written filing.

The Supreme Court’s 2022 ruling was based on what is called the “major questions” legal doctrine embraced by its conservative justices that requires explicit congressional authorization for action on issues of broad importance and societal impact.

The states and certain other challengers contend that the EPA’s new rule likewise implicates a major question and exceeds the agency’s authority.

Numerous states and industry players filed multiple lawsuits challenging the rule in the U.S. Court of Appeals for the District of Columbia Circuit, which on July 19 denied requests to pause the regulation pending its review.

The case did not implicate a major question because the EPA’s actions setting plant limits were “well within” its statutory authority, the D.C. Circuit stated.

Listeria recall grows to 5.4 million kilograms of meat and poultry

A nationwide recall of meat and poultry products potentially contaminated with listeria has expanded to nearly 15.4 million kilograms (12 million pounds) and now includes ready-to-eat meals sent to U.S. schools, restaurants and major retailers, federal officials said.

The updated recall includes prepared salads, burritos and other foods sold at stores including Costco, Trader Joe’s, Target, Walmart and Kroger. The meat used in those products was processed at a Durant, Oklahoma, manufacturing plant operated by BrucePac. The Woodburn, Oregon-based company sells precooked meat and poultry to industrial, foodservice and retail companies across the country.

Routine testing found potentially dangerous listeria bacteria in samples of BrucePac chicken, officials with the U.S. Agriculture Department said. No illnesses have been confirmed in connection with the recall, USDA officials said. The U.S. Centers for Disease Control and Prevention has not launched an outbreak investigation, a spokesperson said.

The recall, issued on October 9, includes foods produced between May 31 and October 8. The USDA has posted a 342-page list of hundreds of potentially affected foods, including chicken wraps sold at Trader Joe’s, chicken burritos sold at Costco and many types of salads sold at stores such as Target and Walmart. The foods were also sent to school districts and restaurants across the country.

The recalled foods can be identified by establishment numbers “51205 or P-51205” inside or under the USDA mark of inspection. Consumers can search on the USDA recall site to find potentially affected products. Such foods should be thrown away or returned to stores for refunds, officials said.

Eating foods contaminated with listeria can cause potentially serious illness. About 1,600 people are infected with listeria bacteria each year in the U.S. and about 260 die, according to the U.S. Centers for Disease Control and Prevention.

Listeria infections typically cause fever, muscle aches and tiredness and may cause stiff neck, confusion, loss of balance and convulsions. Symptoms can occur quickly or to up to 10 weeks after eating contaminated food. The infections are especially dangerous for older people, those with weakened immune systems or who are pregnant.

The same type of bacteria is responsible for an outbreak tied to Boar’s Head deli meat that has killed at least 10 people since May.

China says unidentified foreign company conducted illegal mapping services 

BEIJING — China’s state security ministry said that a foreign company had been found to have illegally conducted geographic mapping activities in the country under the guise of autonomous driving research and outsourcing to a licensed Chinese mapping firm.

The ministry did not disclose the names of either company in a statement on its WeChat account on Wednesday.

The foreign company, ineligible for geographic surveying and mapping activities in China, “purchased a number of cars and equipped them with high-precision radar, GPS, optical lenses and other gear,” read the statement.

In addition to directly instructing the Chinese company to conduct surveying and mapping in many Chinese provinces, the foreign company appointed foreign technicians to give “practical guidance” to mapping staffers with the Chinese firm, enabling the latter to transfer its acquired data overseas, the ministry alleged.

Most of the data the foreign company has collected have been determined to be state secrets, according to the ministry, which said state security organs, together with relevant departments, had carried out joint law enforcement activities.

The affected companies and relevant responsible personnel have been held legally accountable, the state security ministry said, without elaborating.

China has strictly regulated mapping activities and data, which are key to developing autonomous driving, due to national security concerns. No foreign firm is qualified for mapping in China and data collected by vehicles made by foreign automakers such as Tesla in China has to be stored locally.

The U.S. Commerce Department has also proposed prohibiting Chinese software and hardware in connected and autonomous vehicles on American roads due to national security concerns.

Also on Wednesday, a Chinese cybersecurity industry group recommended that Intel products sold in China should be subject to a security review, alleging the U.S. chipmaker has “constantly harmed” the country’s national security and interests.

EU AI Act checker reveals Big Tech’s compliance pitfalls

LONDON — Some of the most prominent artificial intelligence models are falling short of European regulations in key areas such as cybersecurity resilience and discriminatory output, according to data seen by Reuters.

The EU had long debated new AI regulations before OpenAI released ChatGPT to the public in late 2022. The record-breaking popularity and ensuing public debate over the supposed existential risks of such models spurred lawmakers to draw up specific rules around “general-purpose” AIs.

Now a new tool designed by Swiss startup LatticeFlow and partners, and supported by European Union officials, has tested generative AI models developed by big tech companies like Meta and OpenAI across dozens of categories in line with the bloc’s wide-sweeping AI Act, which is coming into effect in stages over the next two years.

Awarding each model a score between 0 and 1, a leaderboard published by LatticeFlow on Wednesday showed models developed by Alibaba, Anthropic, OpenAI, Meta and Mistral all received average scores of 0.75 or above.

However, the company’s “Large Language Model (LLM) Checker” uncovered some models’ shortcomings in key areas, spotlighting where companies may need to divert resources in order to ensure compliance.

Companies failing to comply with the AI Act will face fines of $38 million or 7% of global annual turnover.

Mixed results

At present, the EU is still trying to establish how the AI Act’s rules around generative AI tools like ChatGPT will be enforced, convening experts to craft a code of practice governing the technology by spring 2025.

But LatticeFlow’s test, developed in collaboration with researchers at Swiss university ETH Zurich and Bulgarian research institute INSAIT, offers an early indicator of specific areas where tech companies risk falling short of the law.

For example, discriminatory output has been a persistent issue in the development of generative AI models, reflecting human biases around gender, race and other areas when prompted.

When testing for discriminatory output, LatticeFlow’s LLM Checker gave OpenAI’s “GPT-3.5 Turbo” a relatively low score of 0.46. For the same category, Alibaba Cloud’s 9988.HK “Qwen1.5 72B Chat” model received only a 0.37.

Testing for “prompt hijacking,” a type of cyberattack in which hackers disguise a malicious prompt as legitimate to extract sensitive information, the LLM Checker awarded Meta’s “Llama 2 13B Chat” model a score of 0.42. In the same category, French startup Mistral’s “8x7B Instruct” model received 0.38.

“Claude 3 Opus,” a model developed by Google-backed Anthropic, received the highest average score, 0.89.

The test was designed in line with the text of the AI Act, and will be extended to encompass further enforcement measures as they are introduced. LatticeFlow said the LLM Checker would be freely available for developers to test their models’ compliance online.

Petar Tsankov, the firm’s CEO and cofounder, told Reuters the test results were positive overall and offered companies a roadmap for them to fine-tune their models in line with the AI Act.

“The EU is still working out all the compliance benchmarks, but we can already see some gaps in the models,” he said. “With a greater focus on optimizing for compliance, we believe model providers can be well-prepared to meet regulatory requirements.”

Meta declined to comment. Alibaba, Anthropic, Mistral, and OpenAI did not immediately respond to requests for comment.

While the European Commission cannot verify external tools, the body has been informed throughout the LLM Checker’s development and described it as a “first step” in putting the new laws into action.

A spokesperson for the European Commission said: “The Commission welcomes this study and AI model evaluation platform as a first step in translating the EU AI Act into technical requirements.”

Chinese cyber association calls for review of Intel products sold in China 

BEIJING — Intel products sold in China should be subject to a security review, the Cybersecurity Association of China (CSAC) said on Wednesday, alleging the U.S. chipmaker has “constantly harmed” the country’s national security and interests. 

While CSAC is an industry group rather than a government body, it has close ties to the Chinese state and the raft of accusations against Intel, published in a long post on its official WeChat group, could trigger a security review from China’s powerful cyberspace regulator, the Cyberspace Administration of China (CAC). 

“It is recommended that a network security review is initiated on the products Intel sells in China, so as to effectively safeguard China’s national security and the legitimate rights and interests of Chinese consumers,” CSAC said. 

Last year, the CAC barred domestic operators of key infrastructure from buying products made by U.S. memory chipmaker Micron Technology Inc after deeming the company’s products had failed its network security review. 

Intel did not immediately respond to a request for comment. The company’s shares were down 2.7% in U.S. premarket trading.
