Global temperatures are likely to reach new highs this year with the predicted onset of El Nino, a natural occurring phenomenon typically associated with the warming of the planet.

“The development of an El Nino will most likely lead to a new spike in global heating and increase the chance of breaking temperature records,” said Petteri Taalas, secretary-general of the World Meteorological Organization.

That is bad news for global efforts to reduce climate change. Taalas noted that the onset of El Nino follows the eight warmest years on record “even though we had a cooling La Nina for the past three years and this acted as a temporary brake on global temperature increase.”

El Nino is a naturally occurring climate pattern associated with the warming of ocean surface temperatures in the central and eastern tropical Pacific Ocean. On the other hand, La Nina refers to the periodic cooling of ocean surface temperatures.

The recent unusually long running La Nina event, which began in 2020 now has ended.

Wilfran Moufouma Okia, head of the WMO regional climate prediction services division, said scientific models show that La Nina currently is in a neutral state and moving toward a different phase.

“The next few months from May to July, we have a 60% chance to enter into an El Nino phase. This likelihood will increase to 70% in the period of July to August, and even to 80% if we go past August,” he said. “But, of course, beyond that we cannot say much.”

He said the evolution of El Nino this year will change the weather and climate pattern worldwide compared to what existed during the past three consecutive years of La Nina.

“If we think of La Nina as a sort of break in the warming engine, La Nina corresponds to a cooling of the ocean, which normally should kind of slow down the rise of temperature, El Nino will fuel the temperature globally.

“So, we are expecting in the coming two years to have a serious increase in the global temperature,” he said.

Scientists say the concentrations of two important greenhouse gases, methane and carbon dioxide, which lead to global warming and climate change, go up significantly during an El Nino year.

The WMO says the effect on global temperatures usually plays out in the year after El Nino’s development and likely will become apparent in 2024.

“The world should prepare for the development of El Nino, which is often associated with increased heat, drought or rainfall in different parts of the world,” said Taalas.

“It might bring respite from the drought in the Horn of Africa and other La Nina-related impacts but could also trigger more extreme weather and climate events.”

For example, the WMO said El Nino is likely to trigger heavy rainfall in parts of southern South America, the southern United States, the Horn of Africa, and central Asia.

In contrast, El Nino can cause severe droughts over Australia, Indonesia, and parts of southern Asia.

WMO chief Talaas warns the extreme weather events that will be unleashed by El Nino “highlights the need for the U.N. ‘Early Warnings for All’ initiative to keep people safe.”

Since no two El Nino events are the same and the effects depend partly on the time of year, meteorologists say the WMO and National Meteorological Hydrological Services will be closely monitoring developments.

A panel of global health experts will meet Thursday to decide if COVID-19 is still an emergency under the World Health Organization’s rules, a status that helps maintain international focus on the pandemic.

The WHO first gave COVID its highest level of alert on Jan. 30, 2020, and the panel has continued to apply the label ever since, at meetings held every three months.

However, several countries have recently begun lifting their domestic states of emergency, such as the United States.

WHO Director-General Dr. Tedros Adhanom Ghebreyesus has said he hopes to end the international emergency this year.

There is no consensus yet on which way the panel may rule, advisers to the WHO and external experts told Reuters.

“It is possible that the emergency may end, but it is critical to communicate that COVID remains a complex public health challenge,” said professor Marion Koopmans, a Dutch virologist who is on the WHO panel. She declined to speculate further ahead of the discussions, which are confidential.

One source close to negotiations said lifting the “public health emergency of international concern,” or PHEIC, label could impact global funding or collaboration efforts. Another said that the unpredictability of the virus made it hard to call at this stage.

“We are not out of the pandemic, but we have reached a different stage,” said professor Salim Abdool Karim, a leading COVID expert who previously advised the South African government on its response.

Karim, who is not on the WHO panel, said if the emergency status is lifted, governments should still maintain testing, vaccination and treatment programs.

Others said it was time to move to living with COVID as an ongoing health threat, like HIV or tuberculosis.

“All emergencies must come to an end,” said Lawrence Gostin, a law professor at Georgetown University in the United States who follows the WHO.

“I expect WHO to end the public health emergency of international concern. If WHO does not end it… [this time], then certainly the next time the emergency committee meets.”

Providing further proof that U.S. children suffered significant learning loss when schools were closed during the COVID-19 pandemic, the National Assessment Governing Board released a report Wednesday that showed test scores measuring achievement in U.S. history and civics fell significantly between 2018 and 2022.

The tests, part of the National Assessment of Educational Progress (NAEP), commonly known as the “nation’s report card,” were given to hundreds of eighth-grade students across the country. Scores on the U.S. history assessment were the lowest recorded since 1994, while the scores on the civics test fell for the first time ever.

Only 13% of students tested in U.S. history were considered proficient, meaning that they had substantially mastered the material expected of them. That was 1 percentage point lower than in 2018. Another 46% tested at the NAEP “basic” level, meaning they had partial mastery of the material, down 4 percentage points. The remaining 40% of students tested did not meet the bar for basic knowledge, an increase of 6 percentage points.

In civics, 20% of students tested qualified as proficient, and 48% had basic knowledge of the material — both down 1 percentage point from 2018. Another 31% failed to demonstrate even basic knowledge, an increase by 4 percentage points over 2018.

In both cases, declines in proficiency were concentrated among lower-performing students, while achievement among the top 25% of students was little changed.

Further breakdowns of the data indicated that declines were notably larger among racial minorities and lower-income students, indicating that the impact of the pandemic on educational achievement was not evenly distributed across the population.

Echoes of past warnings

The results issued Wednesday, like those of other NAEP assessments released last year, demonstrated that a decline in educational achievement was exacerbated by lengthy school closures during the pandemic.

In a statement, National Assessment Governing Board Chair Beverly Perdue, a former governor of North Carolina, said the results should be a call to action.

“The wake-up calls keep coming,” she said. “Education leaders and policy makers must create opportunities for students to gain the knowledge and skills they need to catch up and thrive. The students who took these tests are in high school today and will soon enter college and the workforce without the knowledge and skills they need to fully participate in civic life and our democracy.”

U.S. lags in education

Even before the pandemic took hold, experts were sounding alarms about the state of education in the U.S. In 2019, the year before pandemic-related shutdowns began, results of the Program for International Student Assessment, commonly known as PISA, showed U.S. students lagging behind their peers in East Asia and Europe.

The results ranked U.S. students 13th in reading, 18th in science, and 37th in mathematics when compared to a global sample of their peers.

Consistently at the top of each category were China, where only four mainland provinces participated, and Singapore. The U.S. consistently trailed its northerly neighbor, Canada, in all three categories. It also lagged the English-speaking United Kingdom and Australia in all categories except reading.

‘New human crisis’

The U.S. was not the only country where learning suffered because of the coronavirus pandemic. In January, the World Bank issued a report describing pandemic-related learning loss as a “mass casualty event” that, at one time or another, forced 1.4 billion students around the world to miss significant time in the classroom.

Stephen Heyneman, professor emeritus of international education policy at Vanderbilt University and the editor in chief of the International Journal of Educational Development, told VOA that the pandemic-related education crisis is “the worst we’ve had in my lifetime.”

In an editorial published in the May edition of the journal, an editorial board made up of nine researchers from universities worldwide assessed evidence of the pandemic’s impact on education and concluded that the world “is on the verge of a new human crisis.”

The researchers confirmed that in the relatively wealthy industrialized countries, known as the Global North, the poor felt pandemic-related educational impacts most deeply, while financially well-off families often could mitigate much of the impact on students.

The news was worse for the relatively poorer countries, often referred to as the Global South.

“In the Global South, the learning challenges have proved multi-dimensional and much harder to tackle, given the triple burden of schooling deprivation, learning inequality and learning poverty,” they found.

The disparities, first noted early in the pandemic, have continued, the researchers found. “The consensus view is that, despite many promising innovations, learning shortfalls have persisted or even increased, three years into the pandemic.”

Frustration

Asked how the U.S. had performed during the pandemic compared with other developed nations, Heyneman said that “comparison evidence, so far, is too little for me to make any generalizations.”

However, he said, he and his colleagues have noticed — and been frustrated by — a common practice that has been adopted by most public school systems around the world as they have reopened.

Rather than assessing where students had pandemic-related deficits and working to correct them before continuing on with standard curriculums, schools have consistently attempted to simply restart, placing students in the classes and grade levels that correspond to their ages rather than to their actual educational attainment.

“They have not tested the learning loss in any systematic way, and when they have tested, they often haven’t released the scores,” he said. “And whether or not they have tested, they have not treated the results as an emergency. That makes me furious.”

The United States approved the first vaccine for RSV on Wednesday, shots to protect older adults against a respiratory virus that’s most notorious for attacking babies but endangers their grandparents, too.

The Food and Drug Administration decision makes GSK’s shot, called Arexvy, the first of several potential vaccines in the pipeline for RSV to be licensed anywhere.

The move sets the stage for adults 60 and older to get vaccinated this fall — but first, the Centers for Disease Control and Prevention must decide if every senior really needs RSV protection or only those considered at high risk from the respiratory syncytial virus. CDC’s advisers will debate that question in June.

After decades of failure in the quest for an RSV vaccine, doctors are eager to finally have something to offer — especially after a virus surge that strained hospitals last fall.

“This is a great first step … to protect older persons from serious RSV disease,” said Dr. William Schaffner, medical director of the National Foundation for Infectious Diseases, who wasn’t involved with its development. Next, “we’re going to be working our way down the age ladder” for what’s expected to be a string of new protections.

The FDA is considering competitor Pfizer’s similar vaccine for older adults. Pfizer also is seeking approval to vaccinate pregnant women so their babies are born with some of their mothers’ protection.

There isn’t a vaccine for kids yet, but high-risk infants often get monthly doses of a protective drug during RSV season — and European regulators recently approved the first one-dose option. The FDA also is considering whether to approve Sanofi and AstraZeneca’s one-shot medicine.

“This is a very exciting time with multiple potential RSV solutions coming out after years of really nothing,” said Dr. Phil Dormitzer, chief of vaccine research and development for GSK, formerly known as GlaxoSmithKline.

Potentially life-threatening

RSV is a cold-like nuisance for most people, but can be life-threatening for the very young, the elderly, and people with certain high-risk health problems. It can impede babies’ breathing by inflaming their tiny airways, or creep deep into seniors’ lungs to cause pneumonia.

In the U.S., about 58,000 children younger than 5 are hospitalized for RSV each year and several hundred die. Among older adults, as many as 177,000 are hospitalized with RSV and up to 14,000 die annually.

Why has it taken so long to come up with a vaccine? The field suffered a major setback in the 1960s when an experimental shot worsened infections in children. Scientists finally figured out a better way to develop these vaccines — although modern candidates still were first tested with adults.

Study shows high effectiveness rates

GSK’s new vaccine for older adults trains the immune system to recognize a protein on RSV’s surface, and contains an ingredient called an adjuvant to further rev up that immune reaction.

In an international study of about 25,000 people 60 and older, one dose of the vaccine was nearly 83% effective at preventing RSV lung infections and reduced the risk of severe infections by 94%.

To see how long protection lasts, GSK is tracking study participants for three years, comparing some who get just one vaccination during that time and others given a yearly booster.

Shot reactions were typical of vaccinations, such as muscle pain and fatigue.

There was a hint of a rare but serious risk — one case of Guillain-Barre syndrome, which can cause usually temporary paralysis, and two cases of a type of brain and spinal cord inflammation. The FDA said it was requiring the company to continue studying if there really is a link to the vaccine.

If the CDC ultimately recommends the vaccination for some or even all seniors, it will add another shot for the fall along with their yearly flu vaccine — and maybe another COVID-19 booster.

“We’ll have to educate the population that this virus that not everyone has heard about is actually an important threat to their health in the wintertime,” said Schaffner, an infectious-disease expert at Vanderbilt University.

Companies with Brazilian forest concessions would be allowed to generate carbon credits under a bill passed by its Congress this week that marks a first step in regulating the country’s voluntary carbon market.

Private firms have shown little interest in a government program that leases publicly owned forests for sustainable logging, but the legislation could boost the concessions’ appeal with investors by generating an additional revenue stream.

“This is an economic activity that will boost others that can be done in forestry concessions,” said Jacqueline Ferreira, a portfolio manager at Instituto Escolhas, an environmental nonprofit involved in consultations on the bill.

President Luiz Inacio Lula da Silva, who now must sign or veto parts or all of the bill within 15 days, has made reining in deforestation a priority as he seeks to reverse the policies of his right-wing predecessor, Jair Bolsonaro.

Forest leased to private firms in Brazil can only be used for logging under a sustainable system that allows the land to regenerate.

Potential to generate millions

Set up in 2006, the leasing program has had limited success, data shows, with only about 1 million hectares of Brazil’s 43 million hectares of eligible public forest leased.

Studying a typical concession in the Amazon state of Rondonia, Escolhas estimated that carbon credit sales could boost its revenue by 43%.

A wider study by the nonprofit of 37 areas that could be leased in the Amazon region estimated that they could generate about $24 million per year from carbon credits in total.

“This was very conservative math, based on carbon credit prices below the (current) market price,” Ferreira said. She noted that further regulation would be needed to detail the mechanism for generating carbon credits.

She said it would likely take at least a year for the first concessions to be leased that include the ability to issue carbon credits.

The current number of carbon credit projects in Brazil are “small in comparison to the unique potential of the country’s forested area,” said Daniel Vargas, coordinator of the Bioeconomy Observatory within Brazil’s FGV university.

Carbon credits face scrutiny

The bill, however, comes as carbon credits generated by forestry projects in the Amazon region and elsewhere face scrutiny because of land rights issues and a lack of benefits for local communities.

“A growing body of research indicates that no real additional protection is being offered by many of the (carbon credit) projects,” said Eugenio Pantoja, a director at IPAM, a nonprofit that works on sustainability in the Amazon.

The voluntary carbon credit market in Brazil is still unregulated, and while the new bill is a step in that direction, broader legislation will be needed, Pantoja said.

The bill should make concessions more profitable, but a major hurdle for legal logging is stiff competition from illegal, deforested timber, said Suely Araujo, senior expert in public policy at Brazil’s Climate Observatory.

“What is truly hindering (forest concessions) is their difficulty in competing with crime,” Araujo said.

For the first time, scientists have caught a star in the act of swallowing a planet — not just a nibble or bite, but one big gulp.

Astronomers on Wednesday reported their observations of what appeared to be a gas giant around the size of Jupiter or bigger being eaten by its star. The sun-like star had been puffing up with old age for eons and finally got so big that it engulfed the close-orbiting planet.

It’s a gloomy preview of what will happen to Earth when our sun morphs into a red giant and gobbles the four inner planets.

“If it’s any consolation, this will happen in about 5 billion years,” said co-author Morgan MacLeod of the Harvard-Smithsonian Center for Astrophysics.

This galactic feast happened between 10,000 and 15,000 years ago near the Aquila constellation when the star was around 10 billion years old. As the planet went down the stellar hatch, there was a swift hot outburst of light, followed by a long-lasting stream of dust shining brightly in cold infrared energy, the researchers said.

While there had been previous signs of other stars nibbling at planets and their digestive aftermath, this was the first time the swallow itself was observed, according to the study appearing in the journal Nature.

Massachusetts Institute of Technology researcher Kishalay De spotted the luminous outburst in 2020 while reviewing sky scans taken by the California Institute of Technology’s Palomar Observatory. It took additional observations and data-crunching to unravel the mystery: Instead of a star gobbling up its companion star, this one had devoured its planet.

Given a star’s lifetime of billions of years, the swallow itself was quite brief — occurring in essentially one fell swoop, said Caltech’s Mansi Kasliwal, who was part of the study.

The findings are “very plausible,” said Carole Haswell, an astrophysicist at Britain’s Open University, who had no role in the research. Haswell led a team in 2010 that used the Hubble Space Telescope to identify the star WASP-12 in the process of eating its planet.

“This is a different sort of eating. This star gobbled a whole planet in one gulp,” Haswell said in an email. “In contrast, WASP-12 b and the other hot Jupiters we have previously studied are being delicately licked and nibbled.”

Astronomers don’t know if more planets are circling this star at a safer distance. If so, De said they may have thousands of years before becoming the star’s second or third course.

Now that they know what to look for, the researchers will be on the lookout for more cosmic gulps. They suspect thousands of planets around other stars will suffer the same fate as this one did and, eventually, so will our solar system.

“All that we see around us, all the stuff that we’ve built around us, this will all be gone in a flash,” De said.

Eli Lilly and Co. said Wednesday its experimental Alzheimer’s drug appeared to slow worsening of the mind-robbing disease in a large study.

In the 18-month trial, people in the early stages of Alzheimer’s who received infusions of donanemab showed 35% less decline in thinking skills compared with those given a dummy drug, Lilly announced in a press release.

The drug is designed to target and clear away a sticky protein called beta-amyloid that builds up into brain-clogging plaques that are one hallmark of Alzheimer’s.

A similar amyloid-targeting drug, Eisai and Biogen’s Leqembi, recently hit the market with similar evidence that it could modestly slow Alzheimer’s — and also some safety concerns, brain swelling or small brain bleeds.

Donanemab also comes with that risk. Lilly said in its study, the brain side effects caused the deaths of two participants and a third also died after a serious case.

The preliminary study results haven’t been vetted by outside experts. Indianapolis-based Lilly plans to release more details at an international Alzheimer’s meeting this summer and is seeking Food and Drug Administration approval of the drug.

Some 258 million people needed emergency food aid last year because of conflict, economic shocks and climate disasters, a U.N. report said Wednesday, a sharp rise from 193 million the previous year.   

“More than a quarter of a billion people are now facing acute levels of hunger, and some are on the brink of starvation. That’s unconscionable,” U.N. Secretary-General Antonio Guterres said.   

It was “a stinging indictment of humanity’s failure to make progress… to end hunger, and achieve food security and improved nutrition for all,” he said.   

More than 40% of those in serious need of food lived in the Democratic Republic of the Congo, Ethiopia, Afghanistan, Nigeria and Yemen, the U.N. report said.   

“Conflicts and mass displacement continue to drive global hunger,” Guterres said.   

“Rising poverty, deepening inequalities, rampant underdevelopment, the climate crisis and natural disasters also contribute to food insecurity.”   

In 2022, 258 million people faced high levels of acute food insecurity in 58 countries or territories, up from 193 million in 53 countries the previous year, the report said.   

This overall figure has now increased for the fourth year in a row.

A computer scientist often dubbed “the godfather of artificial intelligence” has quit his job at Google to speak out about the dangers of the technology, U.S. media reported Monday.

Geoffrey Hinton, who created a foundation technology for AI systems, told The New York Times that advancements made in the field posed “profound risks to society and humanity”.

“Look at how it was five years ago and how it is now,” he was quoted as saying in the piece, which was published on Monday. “Take the difference and propagate it forwards. That’s scary.”

Hinton said that competition between tech giants was pushing companies to release new AI technologies at dangerous speeds, risking jobs and spreading misinformation.

“It is hard to see how you can prevent the bad actors from using it for bad things,” he told The Times.

Jobs could be at risk

In 2022, Google and OpenAI — the startup behind the popular AI chatbot ChatGPT — started building systems using much larger amounts of data than before.

Hinton told The Times he believed these systems were eclipsing human intelligence in some ways because of the amount of data they were analyzing.

“Maybe what is going on in these systems is actually a lot better than what is going on in the brain,” he told the paper.

While AI has been used to support human workers, the rapid expansion of chatbots like ChatGPT could put jobs at risk.

AI “takes away the drudge work” but “might take away more than that,” he told The Times.

Concern about misinformation

The scientist also warned about the potential spread of misinformation created by AI, telling The Times that the average person will “not be able to know what is true anymore.”

Hinton notified Google of his resignation last month, The Times reported.

Jeff Dean, lead scientist for Google AI, thanked Hinton in a statement to U.S. media.

“As one of the first companies to publish AI Principles, we remain committed to a responsible approach to AI,” the statement added.

“We’re continually learning to understand emerging risks while also innovating boldly.”

In March, tech billionaire Elon Musk and a range of experts called for a pause in the development of AI systems to allow time to make sure they are safe.

An open letter, signed by more than 1,000 people. including Musk and Apple co-founder Steve Wozniak, was prompted by the release of GPT-4, a much more powerful version of the technology used by ChatGPT.

Hinton did not sign that letter at the time, but told The New York Times that scientists should not “scale this up more until they have understood whether they can control it.”

In a massive global crackdown on fentanyl trafficking on the darknet, U.S. and international law enforcement agencies have arrested nearly 300 suspects and seized a large cache of drugs, cash, virtual currency and weapons, officials announced on Tuesday.

The law enforcement action dubbed Operation SpecTor spanned three continents and involved the collaboration of eight countries. It was part of a Justice Department initiative led by the FBI known as JCODE, which aims to dismantle online drug markets.

The operation netted 288 arrests, 850 kilograms of drugs, including 64 kilograms of fentanyl or fentanyl-laced narcotics, $53.4 million in cash and virtual currencies and 117 firearms.

The total number of arrests was the most ever for any JCODE operation and more than double that of the previous operation, officials said.

The Justice Department described the takedown as “the largest international law enforcement operation targeting fentanyl and opioid traffickers on the darknet.”

“Our message to criminals on the dark web is this: You can try to hide in the furthest reaches of the internet, but the Justice Department will find you and hold you accountable for your crimes,” Attorney General Merrick Garland said at a press conference in Washington.

Officials said they collaborated with law enforcement agencies in eight countries, including Austria, France, Germany, Netherlands, Poland, Brazil and the United Kingdom.

The operation is part of a broader effort by U.S. law enforcement agencies to curb fentanyl trafficking.

Last month, the Justice Department announced changes against the Sinaloa Cartel, a notorious drug trafficking organization based in Sinaloa, Mexico, and its facilitators around the world.

Garland described the cartel’s fentanyl trafficking operation as “the largest, most violent, and most prolific” in the world.

The Sinaloa is one of two major Mexican cartels that dominate the U.S. fentanyl market. The other one is known as the Jalisco cartel.

Law enforcement officials say the Sinaloa cartel has been flooding drugs into the United States for more than 15 years.

Officials say the cartels cook fentanyl using precursor chemicals imported from China.

The announcement comes at a time when the U.S. is grappling with an opioid overdose crisis that claimed more than 100,000 American lives in the 12-month period ending in August 2022.

Synthetic opioids such as fentanyl were behind more than two-thirds of the deaths, according to the Centers for Disease Control and Prevention.

The alarming spike in fentanyl deaths has prompted Republican demands that the Biden administration label the cartels as foreign terrorist organizations and unleash the full force of the law against them.

Widespread loneliness in the U.S. poses health risks as deadly as smoking a dozen cigarettes daily, costing the health industry billions of dollars annually, the U.S. surgeon general said Tuesday in declaring the latest public health epidemic.

About half of U.S. adults say they’ve experienced loneliness, Dr. Vivek Murthy said in a report from his office.

“We now know that loneliness is a common feeling that many people experience. It’s like hunger or thirst. It’s a feeling the body sends us when something we need for survival is missing,” Murthy told The Associated Press in an interview. “Millions of people in America are struggling in the shadows, and that’s not right. That’s why I issued this advisory to pull back the curtain on a struggle that too many people are experiencing.”

The declaration is intended to raise awareness around loneliness but won’t unlock federal funding or programming devoted to combatting the issue.

Research shows that Americans, who have become less engaged with worship houses, community organizations and even their own family members in recent decades, have steadily reported an increase in feelings of loneliness. The number of single households has also doubled over the last 60 years.

But the crisis deeply worsened when COVID-19 spread, prompting schools and workplaces to shut their doors and sending millions of Americans to isolate at home away from relatives or friends.

People culled their friend groups during the coronavirus pandemic and reduced time spent with those friends, the surgeon general’s report finds. Americans spent about 20 minutes a day in person with friends in 2020, down from 60 minutes daily nearly two decades earlier.

The loneliness epidemic is hitting young people, ages 15 to 24, especially hard. The age group reported a 70% drop in time spent with friends during the same period.

Loneliness increases the risk of premature death by nearly 30%, with the report revealing that those with poor social relationships also had a greater risk of stroke and heart disease. Isolation also elevates a person’s likelihood for experiencing depression, anxiety and dementia.

The surgeon general is calling on workplaces, schools, technology companies, community organizations, parents and other people to make changes that will boost the country’s connectedness. He advises people to join community groups and put down their phones when they’re catching up with friends; employers to think carefully about their remote work policies; and health systems to provide training for doctors to recognize the health risks of loneliness.

Technology has rapidly exacerbated the loneliness problem, with one study cited in the report finding that people who used social media for two hours or more daily were more than twice as likely to report feeling socially isolated than those who were on such apps for less than 30 minutes a day.

Murthy said social media is driving the increase in loneliness in particular. His report suggests that technology companies roll out protections for children especially around their social media behavior.

“There’s really no substitute for in-person interaction,” Murthy said. “As we shifted to use technology more and more for our communication, we lost out on a lot of that in-person interaction. How do we design technology that strengthens our relationships as opposed to weaken them?”

Scientists said Monday they have found a way to use brain scans and artificial intelligence modeling to transcribe “the gist” of what people are thinking, in what was described as a step toward mind reading.

While the main goal of the language decoder is to help people who have lost the ability to communicate, the U.S. scientists acknowledged that the technology raised questions about “mental privacy.”

Aiming to assuage such fears, they ran tests showing that their decoder could not be used on anyone who had not allowed it to be trained on their brain activity over long hours inside a functional magnetic resonance imaging (fMRI) scanner.

Previous research has shown that a brain implant can enable people who can no longer speak or type to spell out words or even sentences.

These “brain-computer interfaces” focus on the part of the brain that controls the mouth when it tries to form words.

Alexander Huth, a neuroscientist at the University of Texas at Austin and co-author of a new study, said his team’s language decoder “works at a very different level.”

“Our system really works at the level of ideas, of semantics, of meaning,” Huth told an online press conference.

It is the first system to be able to reconstruct continuous language without an invasive brain implant, according to the study in the journal Nature Neuroscience.

‘Deeper than language’

For the study, three people spent a total of 16 hours inside an fMRI machine listening to spoken narrative stories, mostly podcasts such as The New York Times’ “Modern Love.”

This allowed the researchers to map out how words, phrases and meanings prompted responses in the regions of the brain known to process language.

They fed this data into a neural network language model that uses GPT-1, the predecessor of the AI technology later deployed in the hugely popular ChatGPT.

The model was trained to predict how each person’s brain would respond to perceived speech, then narrow down the options until it found the closest response.

To test the model’s accuracy, each participant then listened to a new story in the fMRI machine.

The study’s first author, Jerry Tang, said the decoder could “recover the gist of what the user was hearing.”

For example, when the participant heard the phrase, “I don’t have my driver’s license yet,” the model came back with, “She has not even started to learn to drive yet.”

The decoder struggled with personal pronouns such as “I” or “she,” the researchers admitted.

But even when the participants thought up their own stories — or viewed silent movies — the decoder was still able to grasp the “gist,” they said.

This showed that “we are decoding something that is deeper than language, then converting it into language,” Huth said.

Because fMRI scanning is too slow to capture individual words, it collects a “mishmash, an agglomeration of information over a few seconds,” Huth said. “So, we can see how the idea evolves, even though the exact words get lost.”

Ethical warning

David Rodriguez-Arias Vailhen, a bioethics professor at Spain’s Granada University, which is not involved in the research, said it went beyond what had been achieved by previous brain-computer interfaces.

This brings us closer to a future in which machines are “able to read minds and transcribe thought,” he said, warning this could possibly take place against people’s will, such as when they are sleeping.

The researchers anticipated such concerns.

They ran tests showing that the decoder did not work on a person if it had not already been trained on their own particular brain activity.

The three participants were also able to easily foil the decoder.

While listening to one of the podcasts, the users were told to count by sevens, name and imagine animals or tell a different story in their mind. All these tactics “sabotaged” the decoder, the researchers said.

Next, the team hopes to speed up the process so they can decode the brain scans in real time.

They also called for regulations to protect mental privacy.

“Our mind has so far been the guardian of our privacy,” Rodriguez-Arias said. “This discovery could be a first step towards compromising that freedom in the future.”

Almost a third of the nurses in the United States are considering leaving their profession after the COVID-19 pandemic left them overwhelmed and fatigued, according to a survey.

The survey of over 18,000 nurses, conducted in January by AMN Healthcare Services Inc., showed on Monday that 30% of the participants are looking to quit their career, up 7 percentage points over 2021, when the pandemic-triggered wave of resignations began.

The survey also showed that 36% of the nurses plan to continue working in the sector but may change workplaces.

“This really underscores the continued mental health and well-being challenges the nursing workforce experiences post pandemic,” AMN Healthcare CEO Cary Grace told Reuters in an interview.

The survey showed there are various changes needed, with 69% of nurses seeking increased salaries and 63% of them seeking a safer working environment to reduce their stress.

This comes at a time that hospital operator and sector bellwether HCA Healthcare Inc. indicated a recovery in the staffing situation.

While a shortage of staff in hospitals has been an issue for a couple of years, it gained traction globally in late 2021 and hit a peak early last year following a large number of resignations due to burnout.

The staffing crisis drove up costs at hospital operators, while boosting profits at medical staffing providers such as AMN Healthcare.

Babies born to opioid users had shorter hospital stays and needed less medication when their care emphasized parent involvement, skin-to-skin contact and a quiet environment, researchers reported Sunday.

Newborns were ready to go home about a week earlier compared to those getting standard care. Fewer received opioid medications to reduce withdrawal symptoms such as tremors and hard-to-soothe crying, about 20% compared to 52% of the standard-care babies.

Babies born to opioid users, including mothers in treatment with medications such as methadone, can develop withdrawal symptoms after exposure in the womb.

Typically, hospitals use a scoring system to decide which babies need medicine to ease withdrawal, which means treatment in newborn intensive care units.

“The mom is sitting there anxiously waiting for the score,” said the study’s lead author Dr. Leslie Young of the University of Vermont’s children’s hospital. “This would be really stressful for families.”

In the new approach — called Eat, Sleep, Console — nurses involve mothers as they evaluate together whether rocking, breastfeeding or swaddling can calm the baby, Young said. Medicine is an option, but the environment is considered too.

“Is the TV on in the room? Do we need to turn that off? Are the lights on? Do we need to turn those down?” Young said.

About 5,000 nurses were trained during the study, published Sunday by the New England Journal of Medicine.

Researchers studied the care of 1,300 newborns at 26 U.S. hospitals. Babies born before training were compared to babies born after.

The National Institutes of Health funded the work as part of an initiative to address the U.S. opioid addiction crisis.

“One of the great strengths of the study is its geographic diversity,” said Dr. Diana Bianchi, director of the branch that researches child health and human development. “We’ve had newborns enrolled from sites as varied as Sioux Falls, South Dakota; Kansas City, Missouri; and Spartanburg, South Carolina.”

Many U.S. hospitals have adopted the new approach, Bianchi said, adding she hopes the research will lead to recommendations from pediatrics groups.

Researchers followed the babies for three months and found no difference in urgent care or emergency room visits or hospitalizations — reassuring evidence about the safety of shorter hospital stays.

The new approach could yield “tremendous savings” in hospital resources, Young said, although the study didn’t estimate cost.

Researchers will follow the babies until age 2 to monitor their health.

Mothers want to be involved, Young said.

“For the first time, they feel like their role as a mom is valued and like they’re important,” she said. “We know that those first moments of a mom and a baby being together are really critical to bonding.”

Chinese authorities were preparing Sunday to release a man who disappeared three years ago after publicizing videos of overcrowded hospitals and bodies during the COVID-19 outbreak, a relative and another person familiar with his case said.

Fang Bin and other members of the public who were dubbed citizen journalists posted details of the pandemic in early 2020 on the internet and social media, embarrassing Chinese officials who faced criticism for failing to control the outbreak. The last video Fang, a seller of traditional Chinese clothing, posted on Twitter was of a piece of paper reading, “All citizens resist, hand power back to the people.”

Fang’s case is part of Beijing’s crackdown on criticism of China’s early handling of the pandemic, as the ruling Communist Party seeks to control the narrative of the country.

He was scheduled to be released Sunday, according to two people who did not want to be identified for fear of government retribution. One of them said Fang was sentenced to three years in prison for “picking quarrels and provoking trouble,” a vague charge traditionally used against political dissidents.

The Associated Press could not independently confirm his release and could not confirm the details with the authorities.

Two offices of Wuhan’s public security bureau did not provide a phone number of their information office or answer any questions. Phone calls to a court that reportedly sentenced Fang rang unanswered Sunday afternoon. A woman from another court that had reportedly handled Fang’s appeal said she was not authorized to answer questions.

In early 2020, the initial COVID outbreak devastated the city of Wuhan, home to 11 million residents, in central China’s Hubei province. Under a 76-day lockdown, its streets were deserted for months, apart from ambulances and security personnel.

At that time, a small number of citizen journalists tried to tell their stories and those of others with smart phones and social media accounts, defying the Communist Party’s tightly policed monopoly on information. Although their movement was small, the scale was unprecedented in any previous major disease outbreak or disaster in China.

But the information they posted soon got them into trouble. Fang and another citizen journalist, Chen Qiushi, disappeared in February.

Chen in September 2021 resurfaced on his friend’s live video feed on YouTube, saying he had suffered from depression. But he did not provide details about his disappearance.

Another citizen journalist, Zhang Zhan, who had also reported on the early stage of the outbreak, was sentenced to four years in prison on charges of picking fights and provoking trouble in December 2020. About eight months later, her lawyer said she was in ill health after staging a long-running hunger strike.

The European Union is likely to reach a political agreement this year that will pave the way for the world’s first major artificial intelligence (AI) law, the bloc’s tech regulation chief, Margrethe Vestager, said on Sunday.

This follows a preliminary deal reached on Thursday by members of the European Parliament to push through the draft of the EU’s Artificial Intelligence Act to a vote on May 11. Parliament will then thrash out the bill’s final details with EU member states and the European Commission before it becomes law.

At a press conference after a Group of Seven digital ministers’ meeting in Takasaki, Japan, Vestager said the EU AI Act was “pro-innovation” since it seeks to mitigate the risks of societal damage from emerging technologies.

Regulators around the world have been trying to find a balance where governments could develop “guardrails” on emerging artificial intelligence technology without stifling innovation.

“The reason why we have these guardrails for high-risk use cases is that cleaning up … after a misuse by AI would be so much more expensive and damaging than the use case of AI in itself,” Vestager said.

While the EU AI Act is expected to be passed by this year, lawyers have said it will take a few years for it to be enforced. But Vestager said businesses could start considering the implication of the new legislation.

“There was no reason to hesitate and to wait for the legislation to be passed to accelerate the necessary discussions to provide the changes in all the systems where AI will have an enormous influence,” she told Reuters in an interview.

While research on AI has been going on for years, the sudden popularity of generative AI applications such as OpenAI’S ChatGPT and Midjourney have led to a scramble by lawmakers to find ways to regulate any uncontrolled growth.

An organization backed by Elon Musk and European lawmakers involved in drafting the EU AI Act are among those to have called for world leaders to collaborate to find ways to stop advanced AI from creating disruptions.

Digital ministers of the G-7 advanced nations on Sunday also agreed to adopt “risk-based” regulation on AI, among the first steps that could lead to global agreements on how to regulate AI.

“It is important that our democracy paved the way and put in place the rules to protect us from its abusive manipulation – AI should be useful but it shouldn’t be manipulating us,” said German Transport Minister Volker Wissing.

This year’s G-7 meeting was also attended by representatives from Indonesia, India and Ukraine.

Turkey’s first astronaut will travel to the International Space Station by the end of the year, President Recep Tayyip Erdogan said Saturday.

Air force pilot Alper Gezeravci, 43, was selected to be the first Turkish citizen in space. His backup is Tuva Cihangir Atasever, 30, an aviation systems engineer at Turkish defense contractor Roketsan.

Erdogan made the announcement at the Teknofest aviation and space fair in Istanbul, the president’s first public appearance since falling ill during a TV interview on Tuesday. He appeared alongside Azerbaijan’s president, Ilham Aliyev, and Libya’s interim prime minister, Abdul Hamid Dbeibeh.

“Our friend, who will go on Turkey’s first manned space mission, will stay on the International Space Station for 14 days,” Erdogan said. “Our astronaut will perform 13 different experiments prepared by our country’s esteemed universities and research institutions during this mission.”

Erdogan described Gezeravci as a “heroic Turkish pilot who has achieved significant success in our Air Force Command.”

The Turkish Space Agency website describes Gezeravci as a 21-year air force veteran and F-16 pilot who attended the U.S. Air Force Institute of Technology.

Wearing a red flight jacket, Erdogan appeared in robust health as he addressed crowds at the festival. Turkey’s presidential and parliamentary elections are scheduled for May 14, and opinion polls show Erdogan in potentially his toughest race since he came to power two decades ago.

Turkey is dealing with a prolonged economic downturn, and the government received criticism after a February earthquake killed more than 50,000 in the country. Experts blamed the high death toll in part on shoddy construction and law enforcement of building codes.

While campaigning for reelection, Erdogan has unveiled a number of prestigious projects, such as Turkey’s first nuclear power plant and the delivery of natural gas from Black Sea reserves.

A walrus that became a global celebrity last year after it was seen frolicking and basking in a Oslo fjord before it was euthanized by the authorities has been honored with a bronze sculpture in Norway. 

The life-size sculpture by Norwegian artist Astri Tonoian was unveiled Saturday at the Oslo marina not far from the place where the actual 600-kilogram (1,300-pound) mammal was seen resting and relaxing during the summer of 2022. 

The walrus, named Freya, quickly became a popular attraction among Oslo residents but Norwegian authorities later made a decision to euthanize it — causing public outrage — because they said people hadn’t followed recommendations to keep a safe distance away from the massive animal. 

Norwegian news agency NTB said a crowdfunding campaign was kicked off last fall to finance the sculpture. The private initiative managed to gather about 270,000 Norwegian kroner ($25,000) by October, NTB said.
