Investigators using satellite imagery to document the war in western Sudan’s Darfur region say 72 villages were burned down in April, the most they have seen since the conflict began. Henry Wilkins talks with the people who do this research about how so-called open-source investigations could be crucial in holding those responsible for the violence to account.

Robot will try to remove nuclear debris from Japan’s destroyed reactor
TOKYO — The operator of Japan’s destroyed Fukushima Daiichi nuclear power plant demonstrated Tuesday how a remote-controlled robot would retrieve tiny bits of melted fuel debris from one of three damaged reactors later this year for the first time since the 2011 meltdown.
Tokyo Electric Power Company Holdings plans to deploy a “telesco-style” extendable pipe robot into Fukushima Daiichi No. 2 reactor to test the removal of debris from its primary containment vessel by October.
That work is more than two years behind schedule. The removal of melted fuel was supposed to begin in late 2021 but has been plagued with delays, underscoring the difficulty of recovering from the magnitude 9.0 quake and tsunami in 2011.
During the demonstration at the Mitsubishi Heavy Industries’ shipyard in Kobe, western Japan, where the robot has been developed, a device equipped with tongs slowly descended from the telescopic pipe to a heap of gravel and picked up a granule.
TEPCO plans to remove less than 3 grams (0.1 ounce) of debris in the test at the Fukushima plant.
“We believe the upcoming test removal of fuel debris from Unit 2 is an extremely important step to steadily carry out future decommissioning work,” said Yusuke Nakagawa, a TEPCO group manager for the fuel debris retrieval program. “It is important to proceed with the test removal safely and steadily.”
About 880 tons of highly radioactive melted nuclear fuel remain inside the three damaged reactors. Critics say the 30- to 40-year cleanup target set by the government and TEPCO for Fukushima Daiichi is overly optimistic. The damage in each reactor is different, and plans must accommodate their conditions.
Better understanding the melted fuel debris from inside the reactors is key to their decommissioning. TEPCO deployed four mini drones into the No. 1 reactor’s primary containment vessel earlier this year to capture images from the areas where robots had not reached.

WHO chief urges countries to quickly seal pandemic deal
Geneva — The World Health Organization chief on Monday urged countries to nail down a landmark global agreement on handling of future pandemics after they missed a hard deadline.
Scarred by COVID-19 — which killed millions, shredded economies and crippled health systems — nations have spent two years trying to forge binding commitments on pandemic prevention, preparedness and response.
Negotiators failed to clinch a deal ahead of this week’s World Health Assembly — the annual gathering of WHO’s 194 member states — the deadline for concluding the talks.
WHO chief Tedros Adhanom Ghebreyesus opened the assembly Monday, saying he was confident that an agreement would be secured.
“Of course, we all wish that we had been able to reach a consensus on the agreement in time for this health assembly and crossed the finish line,” he said.
“But I remain confident that you still will, because where there is a will, there is a way.”
Tedros said the task before negotiators had been “immense, technically, legally, and politically”, and that they had been “operating on a very ambitious timeline.”
“You have demonstrated a clear commitment to reaching an agreement,” he said, adding that negotiators had “worked long days and nights,” closing meetings as late as 4:00 a.m.
He hailed their dedication to push forward despite “a torrent of misinformation that was undermining your negotiations.”
While missing Friday’s deadline, countries have voiced a commitment to keep pushing for an accord.
Negotiators are due on Tuesday to present the outcome of the talks to the assembly, which runs until June 1, and the assembly will take stock and decide what to do next.
“I know that there remains among you a common will to get this done, so, there must always be a way,” Tedros said.
“Meaning the solution is in your hands,” he stressed.
Parallel talks have also taken place on revising the International Health Regulations, which were first adopted in 1969 and constitute the existing international legally binding framework for responding to public health emergencies around the world.
The proposed amendments to the IHR, including adding more nuance to a system meant to alert countries to potential health emergencies of global concern, might have a better chance of being adopted during this week’s assembly, observers said.

Military labs do the detective work to identify soldiers decades after they died in World War II
OFFUTT AIR FORCE BASE, Neb. — Generations of American families have grown up not knowing exactly what happened to their loved ones who died while serving their country in World War II and other conflicts.
But a federal lab tucked away above the bowling alley at Offutt Air Force Base near Omaha and a sister lab in Hawaii are steadily answering those lingering questions, aiming to offer 200 families per year the chance to honor their relatives with a proper burial.
“They may not even have been alive when that service member was alive, but that story gets carried down through the generations,” said Carrie Brown, a Defense POW/MIA Accounting Agency lab manager at Offutt. “They may have seen on the mantle a picture of that person when they were little and not really understood or known who they were.”
Memorial Day and the upcoming 80th anniversary of D-Day on June 6 are reminders of the urgency of Brown’s work. The forensic anthropologists, medical examiners and historians who work together to identify lost soldiers are in a race against time as remains buried on battlefields around the globe deteriorate.
But advances in DNA technology, combined with innovative techniques including comparing bones to chest X-rays taken by the military, mean the labs can identify more of the missing soldiers every year. Some 72,000 World War II soldiers remain unaccounted for, along with roughly 10,000 more from all the conflicts since. The experts believe about half of those are recoverable.
The agency identified 59 servicemembers in 2013, when the Offutt lab first opened. That number has steadily risen — 159 service members last year, up from 134 in 2022 — and the labs have a goal of 200 identifications annually.
The labs’ work allowed Donna Kennedy to bury her cousin, Cpl. Charles Ray Patten, with full military honors this month in the same Lawson, Missouri, cemetery where his father and grandfather are buried. Patten died 74 years ago during the Korean War, but spent decades buried as an unknown in the National Memorial Cemetery of the Pacific in Hawaii.
“I just I ached. I mean, it hurt. You know, I just felt so bad. Even though I didn’t know him, I loved him,” Kennedy said.
Patten’s funeral was a simple affair with just a few family members. But often when veterans who fought decades earlier are identified, people waving flags and holding signs line the streets of their hometowns to herald the return of their remains.
“This work is important first and foremost because these are individuals that gave their lives to protect our freedom, and they paid the ultimate sacrifice. So we’re here holding that promise that we’ll return them home to their families,” Brown said.
“It’s important for their families to show them that we’ll never stop, no matter what,” she said.
Often there are compelling details, Brown said.
One of her first cases involved the intact remains of a World War I Marine found in a forest in France with his wallet still in his pocket. The wallet, initialed G.H., contained a New York Times article describing plans for the offensive in which he ultimately died. He also had an infantryman badge with his name and the year he received it on the back.
Before leaving France with the remains, the team visited a local cemetery where other soldiers were buried and learned there were only two missing soldiers with the initials G.H.
Brown had a fair idea who that soldier was before his remains even arrived in the lab. That veteran was buried in Arlington National Cemetery and Brown often visits his grave when she is in Washington D.C.
Most cases aren’t that easy.
The experts who work at the lab must piece together identities by looking at historical records about where the remains were found and which soldiers were in the area. They then consult the list of possible names and use the bones, objects found with them, military medical records and DNA to confirm their identities. They focus on battles and plane crashes where they have the greatest chance of success because of available information.
But their work can be complicated if soldiers were buried in a temporary cemetery and moved when a unit was forced to retreat. And unidentified soldiers were often buried together.
When remains are brought to the lab, they sometimes include an extra bone. Experts then spend months or even years matching the bones and waiting for DNA and other test results to confirm their identities.
One test even can identify if the soldier grew up primarily eating rice or a corn-based diet.
The lab also compares specific traits of collar bones to the chest X-rays the military routinely took of soldiers before they were deployed. It helps that the military keeps extensive records of all soldiers.
Those clues help the experts put together the puzzle of someone’s identity.
“It’s not always easy. It’s certainly not instantaneous,” Brown said. “Some of the cases, we really have to fight to get to that spot, because some of them have been gone for 80 years.”

Life expectancy bouncing back globally after COVID pandemic
London — Life expectancy in Europe has returned to the level it reached before the 2020 coronavirus pandemic, while the U.S. is still trying to regain lost ground. Overall, new numbers show life expectancy has increased in most parts of the world, with eastern sub-Saharan Africa showing the biggest gains over the past three decades.
Latest European Union figures released this month show the average life expectancy across the bloc in 2023 was 81.5 years — almost a year’s gain over 2022, as the coronavirus pandemic was coming to an end.
Jennifer Beam Dowd is a professor of demography and population health at the University of Oxford.
“Within Europe, we’re seeing really high life expectancy in countries like Spain and Italy, Sweden, Norway, but some countries are falling behind their peers and that includes the UK. And then Eastern Europe has made a lot of progress since the post-Soviet mortality crisis of the 1990s, but they’re still lagging behind a bit,” she said.
A recent study in the Lancet journal showed that globally, life expectancy increased by 6.2 years between 1990 and 2021 — with eastern sub-Saharan Africa experiencing the largest increase of some 10.7 years.
“I think that’s really good news and reflects a lot of continued progress all over the world in falls and infectious disease and infant and child mortality, which makes a big difference to life expectancy because you’re saving a lot of years of life if you save lives at young ages,” said Jennifer Beam Dowd.
Figures released in March showed average life expectancy in the United States in 2022, the most recent data available, was 77.5 years — still more than a year lower than the life expectancy before the pandemic. Figures for 2023 have not yet been released.
“A lot of countries have bounced back close to pre-pandemic life expectancy, but some countries such as the U.S. have not returned yet to the levels they were at in 2019,” said Jennifer Beam Dowd. “Another thing that’s having a big impact, we think right now, is the obesity epidemic, which started taking off, especially in the U.S., in the early 1980s. And in fact, we are seeing major slowdowns in improvements from cardiovascular disease that are driving a lot of the stalling life expectancy in high-income countries.”
The European principality of Monaco — a favorite home for the super-rich — had the world’s highest life expectancy in 2023, at almost 90 years, according to U.S. figures.

Report: Tobacco industry uses manipulative practices to hook young people on addictive products
Geneva — The World Health Organization and STOP, a global tobacco industry watchdog, warn the tobacco industry is using a variety of manipulative tactics to hook a new generation of young people into becoming users of their addictive, toxic tobacco and nicotine products for life.
“The terrible truth is that eight million people every year die from tobacco use. The single greatest cause for these deaths is a vast industry that works relentlessly to sell products that are essentially poison,” Jorge Alday, director of STOP at Vital Strategies, said at the recent launch of a new tobacco interference report, “Hooking the next generation.”
Speaking in advance of World No Tobacco Day on May 31, Alday asserted that the tobacco industry’s products kill at least half of the people who use them, therefore, he said, “It has an endless need to replace its customers.”
“From the perspective of a tobacco company, an addictive customer means a lifetime of profits. So, the younger someone gets hooked the more money they can make at the expense of that person’s health,” he said.
The report shows that globally, an estimated 37 million children ages 13 to 15 use tobacco, and in many countries, the rate of e-cigarette use among adolescents exceeds that of adults.
While significant progress has been made in reducing tobacco use, the report says the emergence of e-cigarettes and other new tobacco and nicotine products presents “a grave threat to youth and tobacco control.”
“Studies demonstrate that e-cigarette use increases conventional cigarette use, particularly among non-smoking youth, by nearly three times,” it says.
Ruediger Krech, director of health promotion at WHO, told journalists attending the global launch of the report last week that the industry is “exploiting digital and social media, delivery apps, and other innovative ways to reach our children. At the same time, they are continuing with old tricks such as giving away free samples to recruit a new generation as customers.”
He said the use of child-friendly flavored e-cigarettes combined with sleek and colorful designs that resemble toys “is a blatant attempt” by tobacco and related industries “to addict young people to these harmful products.”
“Currently, we have about 16,000 flavors that are very appealing to children and young people—fruity flavors, candy, bubble gum and vanilla ice-cream,” he said, noting that most adult tobacco users start their deadly habit when they are young.
“Most of them have started before the age of 21. Then they stay tobacco or nicotine users for the rest of their lives,” he said. “That is alarming when we are now seeing that with these novel products, so many children and young people are taking up this nicotine use.
“So, there is an urgency to act now to regulate those products, ban them if possible. But to be very, very serious about this,” he added.
One of many youth advocates around the world taking a stand against “the destructive influence and manipulative marketing practices” of the tobacco and nicotine industry is Given Kapolyo of Zambia. She is the Global Young Ambassador of the Year with the Campaign for Tobacco-Free Kids, CTFK.
“I totally agree with the sentiments shared already today that the industry continues to hook young people,” she said, speaking from the Zambian capital, Lusaka.
“It is extremely sad here in Africa because they continue to target low-income communities because they know that these young people do not have access to information on just how deadly these products are. … They tell young people that vaping is cooler, that electronic cigarettes are cooler, and they continue to hook young people as early as 10 years and 13 years old.
“Their only interest is profits, and they want to hook young people while they are young, so they can have lifelong customers, which means more profits for them, without caring how many lives we are losing due to non-communicable diseases caused by tobacco abuse,” she said.
The World Health Organization is urging governments to protect young people from taking up tobacco, e-cigarettes and other nicotine products by banning or tightly regulating them. Its recommendations include the creation of smoke-free indoor public places, bans on flavored e-cigarettes, as well as bans on marketing, advertising, and promotions, and the enactment of higher taxes.
Authors of the reports say these measures work. They cite an example from the United States where research found that “more than 70 percent of youth e-cigarette users would quit if the products were only available in tobacco flavor.”

New cars in California could alert drivers for breaking the speed limit
SACRAMENTO, California — California could eventually join the European Union in requiring all new cars to alert drivers when they break the speed limit, a proposal aimed at reducing traffic deaths that would likely impact motorists across the country should it become law.
The federal government sets safety standards for vehicles nationwide, which is why most cars now beep at drivers if their seat belt isn’t fastened. A bill in the California Legislature — which passed its first vote in the state Senate on Tuesday — would go further by requiring all new cars sold in the state by 2032 to beep at drivers when they exceed the speed limit by at least 16 kph.
“Research has shown that this does have an impact in getting people to slow down, particularly since some people don’t realize how fast that their car is going,” said state Sen. Scott Wiener, a Democrat from San Francisco and the bill’s author.
The bill narrowly passed Tuesday, an indication of the tough road it could face. Republican state Sen. Brian Dahle said he voted against it in part because he said sometimes people need to drive faster than the speed limit in an emergency.
“It’s just a nanny state that we’re causing here,” he said.
While the goal is to reduce traffic deaths, the legislation would likely impact all new car sales in the U.S. That’s because California’s auto market is so large that car makers would likely just make all of their vehicles comply with the state’s law.
California often throws its weight around to influence national — and international — policy. California has set its own emission standards for cars for decades, rules that more than a dozen other states have also adopted. And when California announced it would eventually ban the sale of new gas-powered cars, major automakers soon followed with their own announcement to phase out fossil-fuel vehicles.
The technology, known as intelligent speed assistance, uses GPS technology to compare a vehicle’s speed with a dataset of posted speed limits. Once the car is at least 16 kph over the speed limit, the system would emit “a brief, one-time visual and audio signal to alert the driver.”
It would not require California to maintain a list of posted speed limits. That would be left to manufacturers. It’s likely these maps would not include local roads or recent changes in speed limits, resulting in conflicts.
The bill states that if the system receives conflicting information about the speed limit, it must use the higher limit.
The technology is not new and has been used in Europe for years. Starting later this year, the European Union will require all new cars sold there to have the technology — although drivers would be able to turn it off.
The National Highway and Traffic Safety Administration estimates that 10% of all car crashes reported to police in 2021 were speeding related — including an 8% increase in speeding-related fatalities. This was especially a problem in California, where 35% of traffic fatalities were speeding-related — the second highest in the country, according to a legislative analysis of the proposal.
Last year, the National Transportation Safety Board recommended federal regulators require all new cars to alert drivers when speeding. Their recommendation came after a crash in January 2022 when a man with a history of speeding violations was traveling more than 100 miles per hour when he ran a red light and hit a minivan, killing himself and eight other people.
The NTSB has no authority and can only make recommendations.

China’s Digital Silk Road exports internet technology, controls
washington — China promotes its help to Southeast Asian countries in modernizing their digital landscapes through investments in infrastructure as part of its “Digital Silk Road.” But rights groups say Beijing is also exporting its model of authoritarian governance of the internet through censorship, surveillance and controls.
China’s state media this week announced Chinese electrical appliance manufacturer Midea Group jointly built its first overseas 5G factory in Thailand with Thai mobile operator AIS, Chinese telecom service provider China Unicom and tech giant Huawei.
The 208,000-square-meter smart factory will have its own 5G network, Xinhua news agency reported.
Earlier this month, Beijing reached an agreement with Cambodia to establish a Digital Law Library of the Association of Southeast Asian Nations (ASEAN) Inter-Parliamentary Assembly. Cambodia’s Khmer Times said the objective is to “expand all-round cooperation in line with the strategic partnership and building a common destiny community.”
But parallel to China’s state media-promoted technology investments, rights groups say Beijing is also helping countries in the region to build what they call “digital authoritarian governance.”
Article 19, an international human rights organization dedicated to promoting freedom of expression globally and named after Article 19 of the Universal Declaration of Human Rights, in an April report said the purpose of the Digital Silk Road is not solely to promote China’s technology industry. The report, China: The rise of digital repression in the Indo-Pacific, says Beijing is also using its technology to reshape the region’s standards of digital freedom and governance to increasingly match its own.
VOA contacted the Chinese Embassy in the U.S. for a response but did not receive one by the time of publication.
Model of digital governance
Looking at case studies of Cambodia, Malaysia, Nepal and Thailand, the Article 19 report says Beijing is spreading China’s model of digital governance along with Chinese technology and investments from companies such as Huawei, ZTE and Alibaba.
Michael Caster, Asia digital program manager with Article 19, told VOA, “China has been successful at providing a needed service, in the delivery of digital development toward greater connectivity, but also in making digital development synonymous with the adoption of PRC [People’s Republic of China]-style digital governance, which is at odds with international human rights and internet freedom principles, by instead promoting notions of total state control through censorship and surveillance, and digital sovereignty away from universal norms.”
The group says in Thailand, home to the world’s largest overseas Chinese community, agreements with China bolstered internet controls imposed after Thailand’s 2014 coup, and it notes that Bangkok has since been considering a China-style Great Firewall, the censorship mechanism Beijing uses to control online content.
In Nepal, the report notes security and intelligence-sharing agreements with China and concerns that Chinese security camera technology is being used to surveil exiled Tibetans, the largest such group outside India.
The group says Malaysia’s approach to information infrastructure appears to increasingly resemble China’s model, citing Kuala Lumpur’s cybersecurity law passed in April and its partnering with Chinese companies whose technology has been used for repressing minorities inside China.
Most significantly, Article 19 says China is involved at “all levels” of Cambodia’s digital ecosystem. Huawei, which is facing increasing bans in Western nations over cybersecurity concerns, has a monopoly on cloud services in Cambodia.
While Chinese companies say they would not hand over private data to Beijing, experts doubt they would have any choice because of national security laws.
Internet gateway
Phnom Penh announced a decree in 2021 to build a National Internet Gateway similar to China’s Great Firewall, restricting the Cambodian people’s access to Western media and social networking sites.
“That we have seen the normalization of a China-style Great Firewall in some of the countries where China’s influence is most pronounced or its digital development support strongest, such as with Cambodia, is no coincidence,” Caster said.
The Cambodian government says the portal will strengthen national security and help combat tax fraud and cybercrime. But the Internet Society, a U.S.- and Switzerland-based nonprofit internet freedom group, says it would allow the government to monitor individual internet use and transactions, and to trace identities and locations.
Kian Vesteinsson, a senior researcher for technology and democracy with rights group Freedom House, told VOA, “The Chinese Communist Party and companies that are aligned with the Chinese state have led a charge internationally to push for internet fragmentation. And when I say internet fragmentation, I mean these efforts to carve out domestic internets that are isolated from global internet traffic.”
Despite Chinese support and investment, Vesteinsson notes that Cambodia has not yet implemented the plan for a government-controlled internet.
“Building the Chinese model of digital authoritarianism into a country’s internet infrastructure is extraordinarily difficult. It’s expensive. It requires technical capacity. It requires state capacity, and all signs point to the Cambodian government struggling on those fronts.”
Vesteinsson says while civil society and foreign political pressure play a role, business concerns are also relevant as requirements to censor online speech or spy on users create costs for the private sector.
“These governments that are trying to cultivate e-commerce should keep in mind that a legal environment that is free from these obligations to do censorship and surveillance will be more appealing to companies that are evaluating whether to start up domestic operations,” he said.
Article 19’s Caster says countries concerned about China’s authoritarian internet model spreading should do more to support connectivity and internet development worldwide.
“This support should be based on human rights law and internet freedom principles,” he said, “to prevent China from exploiting internet development needs to position its services – and often by extension its authoritarian model – as the most accessible option.”
China will hold its annual internet conference in Beijing July 9-11. China’s Xinhua news agency reports this year’s conference will discuss artificial intelligence, digital government, information technology application innovation, data security and international cooperation.

Italian museum recreates Tanzanian butterfly forest
TRENTO, Italy — In a lush greenhouse high in the Alps, butterflies of various species and colors flutter freely while butterfly pupae are suspended in a structure as they grow into adult insects.
This is the Butterfly Forest in the tropical mountain greenhouse in Trento, Italy, a project by the Museo delle Scienze (MUSE), an Italian science museum. It’s modeled on Udzungwa Mountains, a mountain range and rainforest area in south-central Tanzania that’s one of the world’s biodiversity hotspots. The Butterfly Forest features plant species endemic to the region, as well as birds, reptiles, amphibians, fish and invertebrates from different parts of the world, all inside 600 square meters of forest with cliffs, inclinations and a waterfall.
The Butterfly Forest was created this spring to create public awareness on some of the research that MUSE is doing in Udzungwa Mountains to study and protect the world’s biodiversity against threats such as deforestation and climate change.
Deforestation leads to habitat loss, which causes declines in nectar sources for butterflies, changing the functioning of the ecosystem. It can also limit the movements of the insects causing a decline in biodiversity and potential extinction of vulnerable butterfly species. Changes to soil and air temperatures are altering the life cycles of the insects, impacting their development rates, mating behaviors, and migration patterns. Butterfly populations are declining in many areas, especially in places under intensive land use.
“Our aim is that of being able to study better, to understand better what is happening,” said Lisa Angelini, a botanist and director of the MUSE greenhouse. “Our work consists of monitoring and trying to develop projects in order to bring attention to biodiversity-related issues.”
Butterflies are pollinators that enable plants to reproduce and therefore facilitate food production and supply. They are also food for birds and other animals.
Because of the multiple roles of butterflies in the ecosystem and their high sensitivity to environmental changes, scientists use them as indicators of biodiversity and a way to study the impact of habitat loss and other threats. “Insects in general play a fundamental role in the proper functioning of ecosystems,” said Mauro Gobbi, an entomologist and researcher at MUSE.
Through a partnership with the Tanzania National Parks Authority, MUSE established the Udzungwa Ecological Monitoring Center in 2006 to support research as well as in development of environmental education programs for schools.
“Research on butterflies is essential for informing conservation efforts and ensuring the long-term survival of the insects,” said Arafat Mtui, research coordinator at Udzungwa Ecological Monitoring Centre. Conservation efforts such as habitat restoration and good land management practices, which address climate change impacts, are essential for protecting butterfly populations, he added.
With at least 2,500 plant species, more than 120 mammals, and thousands of invertebrate species, Udzungwa Mountains is rich in biological diversity. It’s part of the Eastern Arc Mountains of Kenya and Tanzania that are a proposed UNESCO Heritage site. It has more than 40 endemic species of butterflies.
MUSE’s work here is vital because of this variety, said Sevgan Subramanian, principal scientist and head of environmental health at the International Centre of Insect Physiology and Ecology in Nairobi.
“If you want to have a monitoring of the health of the ecosystem, monitoring such indigenous or endemic insect population diversity is very critical, so that we have an idea whether the ecosystem is still healthy or not,” he said.
Gobbi, the entomologist, said high-altitude environments like Udzungwa Mountains National Park are suitable for studying the effects of climate change because they usually have no direct human impact.
He and other scientists have warned that failure to protect insects from climate change effects will drastically reduce the planet’s ability to build a sustainable future.
Scientists at MUSE said the main challenge in butterfly conservation is changing the current farming policies to increase the amount of low-intensity farmland, and promote diverse landscapes preserving the remaining patches of natural habitats.
“Often our grandparents used to say ‘there are no longer as many butterflies as there used to be,'” he said. This is “absolutely supported by scientific research, which confirms that butterflies, like other insects, are in crisis. We are losing species, we’re losing them forever, and this is going to break the balance of ecosystems.”

Attempts to regulate AI’s hidden hand in Americans’ lives flounder
DENVER — The first attempts to regulate artificial intelligence programs that play a hidden role in hiring, housing and medical decisions for millions of Americans are facing pressure from all sides and floundering in statehouses nationwide.
Only one of seven bills aimed at preventing AI’s penchant to discriminate when making consequential decisions — including who gets hired, money for a home or medical care — has passed. Colorado Gov. Jared Polis hesitantly signed the bill on Friday.
Colorado’s bill and those that faltered in Washington, Connecticut and elsewhere faced battles on many fronts, including between civil rights groups and the tech industry, and lawmakers wary of wading into a technology few yet understand and governors worried about being the odd-state-out and spooking AI startups.
Polis signed Colorado’s bill “with reservations,” saying in an statement he was wary of regulations dousing AI innovation. The bill has a two-year runway and can be altered before it becomes law.
“I encourage (lawmakers) to significantly improve on this before it takes effect,” Polis wrote.
Colorado’s proposal, along with six sister bills, are complex, but will broadly require companies to assess the risk of discrimination from their AI and inform customers when AI was used to help make a consequential decision for them.
The bills are separate from more than 400 AI-related bills that have been debated this year. Most are aimed at slices of AI, such as the use of deepfakes in elections or to make pornography.
The seven bills are more ambitious, applying across major industries and targeting discrimination, one of the technology’s most perverse and complex problems.
“We actually have no visibility into the algorithms that are used, whether they work or they don’t, or whether we’re discriminated against,” said Rumman Chowdhury, AI envoy for the U.S. Department of State who previously led Twitter’s AI ethics team.
While anti-discrimination laws are already on the books, those who study AI discrimination say it’s a different beast, which the U.S. is already behind in regulating.
“The computers are making biased decisions at scale,” said Christine Webber, a civil rights attorney who has worked on class action lawsuits over discrimination including against Boeing and Tyson Foods. Now, Webber is nearing final approval on one of the first-in-the-nation settlements in a class action over AI discrimination.
“Not, I should say, that the old systems were perfectly free from bias either,” said Webber. But “any one person could only look at so many resumes in the day. So you could only make so many biased decisions in one day and the computer can do it rapidly across large numbers of people.”
When you apply for a job, an apartment or a home loan, there’s a good chance AI is assessing your application: sending it up the line, assigning it a score or filtering it out. It’s estimated as many as 83% of employers use algorithms to help in hiring, according to the Equal Employment Opportunity Commission.
AI itself doesn’t know what to look for in a job application, so it’s taught based on past resumes. The historical data that is used to train algorithms can smuggle in bias.
Amazon, for example, worked on a hiring algorithm that was trained on old resumes: largely male applicants. When assessing new applicants, it downgraded resumes with the word “women’s” or that listed women’s colleges because they were not represented in the historical data — the resumes — it had learned from. The project was scuttled.
Webber’s class action lawsuit alleges that an AI system that scores rental applications disproportionately assigned lower scores to Black or Hispanic applicants. A study found that an AI system built to assess medical needs passed over Black patients for special care.
Studies and lawsuits have allowed a glimpse under the hood of AI systems, but most algorithms remain veiled. Americans are largely unaware that these tools are being used, polling from Pew Research shows. Companies generally aren’t required to explicitly disclose that an AI was used.
“Just pulling back the curtain so that we can see who’s really doing the assessing and what tool is being used is a huge, huge first step,” said Webber. “The existing laws don’t work if we can’t get at least some basic information.”
That’s what Colorado’s bill, along with another surviving bill in California, are trying to change. The bills, including a flagship proposal in Connecticut that was killed under opposition from the governor, are largely similar.
Colorado’s bill will require companies using AI to help make consequential decisions for Americans to annually assess their AI for potential bias; implement an oversight program within the company; tell the state attorney general if discrimination was found; and inform to customers when an AI was used to help make a decision for them, including an option to appeal.
Labor unions and academics fear that a reliance on companies overseeing themselves means it’ll be hard to proactively address discrimination in an AI system before it’s done damage. Companies are fearful that forced transparency could reveal trade secrets, including in potential litigation, in this hyper-competitive new field.
AI companies also pushed for, and generally received, a provision that only allows the attorney general, not citizens, to file lawsuits under the new law. Enforcement details have been left up to the attorney general.
While larger AI companies have more or less been on board with these proposals, a group of smaller Colorado-based AI companies said the requirements might be manageable by behemoth AI companies, but not by budding startups.
“We are in a brand new era of primordial soup,” said Logan Cerkovnik, founder of Thumper.ai, referring to the field of AI. “Having overly restrictive legislation that forces us into definitions and restricts our use of technology while this is forming is just going to be detrimental to innovation.”
All agreed, along with many AI companies, that what’s formally called “algorithmic discrimination” is critical to tackle. But they said the bill as written falls short of that goal. Instead, they proposed beefing up existing anti-discrimination laws.
Chowdhury worries that lawsuits are too costly and time consuming to be an effective enforcement tool, and laws should instead go beyond what even Colorado is proposing. Instead, Chowdhury and academics have proposed accredited, independent organization that can explicitly test for potential bias in an AI algorithm.
“You can understand and deal with a single person who is discriminatory or biased,” said Chowdhury. “What do we do when it’s embedded into the entire institution?”

Scientists: Climate change, rapid urbanization worsen impact of East African rains
NAIROBI, Kenya — The impact of the calamitous rains that struck East Africa from March to May was intensified by a mix of climate change and rapid growth of urban areas, an international team of climate scientists said in a study published Friday.
The findings come from World Weather Attribution, a group of scientists that analyzes whether and to what extent human-induced climate change has altered the likelihood and magnitude of extreme weather events.
The downpours caused floods that killed hundreds of people, displaced thousands of others, killed thousands of livestock and destroyed thousands of acres of crops.
To assess how human-caused climate may have affected the floods, the researchers analyzed weather data and climate model simulations to compare how these types of events have changed between today’s climate and the cooler pre-industrial one. They focused on regions where the impacts were most severe, including southern Kenya, most of Tanzania and a part of Burundi.
It found that climate change had made the devastating rains twice as likely and 5% more intense. The study also found that with further warming, the frequency and intensity of the rains would continue to increase.
“We’re likely to see this kind of intensive rainfall happening this season going into the future,” said Joyce Kimutai, research associate at Imperial College London and the lead author of the study.
The study also found that the rapid urbanization of East African cities is increasing the risk of flooding.
Highly populated urban areas, especially high-density informal settlements, were significantly impacted by the downpours. Torrential rain flooded houses and roads, in some places exposing weaknesses in urban planning to meet the demands of fast-growing populations.
March to May is “long rains” season in East Africa. It’s when most of the region’s average annual rainfall occurs, and is typically characterized by torrential rains.
East Africa also suffered flooding during the “short rains” of October to December 2023 and before that, it endured a three-year drought. WWA scientists found that both events were worsened by climate change.
Philip Omondi, climate change specialist at the IGAD Climate Prediction and Applications Centre in Nairobi and wasn’t involved in the study, said human-caused impacts result in intense and high-frequency extreme floods and droughts.
Shaun Ferris, senior technical advisor for agriculture and climate change at Catholic Relief Services in Nairobi, said more intense weather put a new level of pressure on old and unplanned buildings and basic infrastructure and there’s a need to put up infrastructure that will be more able to cope with climate change.
“There is huge pressure on basic services,” he said giving the example of Nairobi, whose population has doubled over the past 20 years.
Ferris said that the global community needs to start using the loss and damage fund for climate disasters so they can repair and upgrade their basic infrastructure.

World’s largest tree passes health check
SEQUOIA NATIONAL PARK, California — High in the evergreen canopy of General Sherman, the world’s largest tree, researchers searched for evidence of an emerging threat to giant sequoias: bark beetles.
The climbers descended the towering 2,200-year-old tree with good news on Tuesday.
“The General Sherman tree is doing fine right now,” said Anthony Ambrose, executive director of the Ancient Forest Society, who led the expedition. “It seems to be a very healthy tree that’s able to fend off any beetle attack.”
It was the first time climbers had scaled the iconic 85-meter sequoia tree, which draws tourists from around the world to Sequoia National Park.
Giant sequoias, the Earth’s largest living things, have survived for thousands of years in California’s western Sierra Nevada range, the only place where the species is native.
But as the climate grows hotter and drier, giant sequoias previously thought to be almost indestructible are increasingly threatened by extreme heat, drought and wildfires.
In 2020 and 2021, record-setting wildfires killed as much as 20% of the world’s 75,000 mature sequoias, according to park officials.
“The most significant threat to giant sequoias is climate-driven wildfires,” said Ben Blom, director of stewardship and restoration at Save the Redwoods League. “But we certainly don’t want to be caught by surprise by a new threat, which is why we’re studying these beetles now.”
But researchers are growing more worried about bark beetles, which didn’t pose a serious threat in the past.
The beetles are native to California and have co-existed with sequoias for thousands of years. But only recently have they been able to kill the trees. Scientists say they recently discovered about 40 sequoia trees that have died from beetle infestations, mostly within the national parks.
“We’re documenting some trees that are actually dying from kind of a combination of drought and fire that have weakened them to a point where they’re not able to defend themselves from the beetle attack,” Ambrose said.
The beetles attack the trees from the canopy, boring into branches and working their way down the trunk. If left unchecked, the tiny beetles can kill a tree within six months.
That’s why park officials allowed Ambrose and his colleagues to climb General Sherman. They conducted the tree health inspection as journalists and visitors watched them pull themselves up ropes dangling from the canopy. They examined the branches and trunk, looking for the tiny holes that indicate beetle activity.
But it’s not possible to climb every sequoia tree to directly inspect the canopy in person. That’s why they’re also testing whether drones equipped with sensors and aided by satellite imagery can be used to monitor and detect beetle infestations on a larger scale within the forests.
Tuesday’s health inspection of General Sherman was organized by the Giant Sequoia Lands Coalition, a group of government agencies, Native tribes and environmental groups. They hope to establish a health monitoring program for the towering trees.
If they discover beetle infestations, officials say, they could try to combat the attacks by spraying water, removing branches or using chemical treatments.
Bark beetles have ravaged pine and fir forests throughout the Western United States in recent years, but they previously didn’t pose a threat to giant sequoias, which can live 3,000 years.
“They have really withstood insect attacks for a lot of years. So why now? Why are we seeing this change?” said Clay Jordan, superintendent for Sequoia and Kings Canyon National Parks. “There’s a lot that we need to learn in order to ensure good stewardship of these trees for a long time.”

IS turns to artificial intelligence for advanced propaganda amid territorial defeats
Washington — With major military setbacks in recent years, supporters of the Islamic State terror group are increasingly relying on artificial intelligence (AI) to generate online propaganda, experts said.
A new form of propaganda developed by IS supporters is broadcasting news bulletins with AI-generated anchors in multiple languages.
The Islamic State Khorasan (ISKP) group, an IS affiliate active in Afghanistan and Pakistan, produced in a video an AI-generated anchorman to appear reading news following an IS-claimed attack in Bamiyan province in Afghanistan on May 17 that killed four people, including three Spanish tourists.
The digital image posing as an anchor spoke the Pashto language and had features resembling local residents in Bamiyan, according to The Khorasan Diary, a website dedicated to news and analysis on the region.
Another AI-generated propaganda video by Islamic State appeared on Tuesday with a different digital male news anchor announcing IS’s responsibility for a car bombing in Kandahar, Afghanistan.
“These extremists are very effective in spreading deepfake propaganda,” said Roland Abi Najem, a cybersecurity expert based in Kuwait.
He told VOA that a group like IS was already effective in producing videos with Hollywood-level quality, and the use of AI has made such production more accessible for them.
“AI now has easy tools to use to create fake content whether it’s text, photo, audio or video,” Abi Najem said, adding that with AI, “you only need data, algorithms and computing power, so anyone can create AI-generated content from their houses or garages.”
IS formally began using the practice of AI-generated news bulletins four days after an attack at a Moscow music hall on March 22 killed some 145 people. The attack was claimed by IS.
In that video, IS used a “fake” AI-generated news anchor talking about the Moscow attack, experts told The Washington Post last week.
Mona Thakkar, a research fellow at the International Center for the Study of Violent Extremism, said pro-IS supporters have been using character-generation techniques and text-to-speech AI tools to produce translated news bulletins of IS’s Amaq news agency.
“These efforts have garnered positive responses from other users, reflecting that, through future collaborative efforts, many supporters could produce high quality and sophisticated AI-powered propaganda videos for IS of longer durations with better graphics and more innovation techniques,” she told VOA.
Thakkar said she recently came across some pro-IS Arabic-speaking supporters on Telegram who were recommending to other supporters “that beginners use AI image generator bots on Telegram to maintain the high quality of images as the bots are very easy and quick to produce such images.”
AI-generated content for recruitment
While IS’s ability to project power largely decreased due to its territorial defeat in Syria and Iraq, experts say supporters of the terror group believe artificial intelligence offers an alternative to promote their extremist ideology.
“Their content has mainly focused on showing that they’re still powerful,” said Abi Najem. “With AI-generated content now, they can choose certain celebrities that have influence, especially on teenagers, by creating deepfake videos.”
“So first they manipulate these people by creating believable content, then they begin recruiting them,” he said.
In a recent article published on the Global Network on Extremism and Technology, researcher Daniel Siegel said generative AI technology has had a profound impact on how extremist organizations engage in influence operations online, including the use of AI-generated Muslim religious songs, known as nasheeds, for recruitment purposes.
“The strategic deployment of extremist audio deepfake nasheeds, featuring animated characters and internet personalities, marks a sophisticated evolution in the tactics used by extremists to broaden the reach of their content,” he wrote.
Siegel said that other radical groups like al-Qaida and Hamas have also begun using AI to generate content for their supporters.
Cybersecurity expert Abi Najem said he believes the cheap technology will increase the availability of AI-generated content by extremist groups on the internet.
“While currently there are no stringent regulations on the use of AI, it will be very challenging for governments to stop extremist groups from exploiting these platforms for their own gain,” he said.
