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.

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.

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 281 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.

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.

By comparing the genetic blueprints of an array of animals, scientists are gaining new insights into our own species and all we share with other creatures. 

One of the most striking revelations is that certain passages in the instructions for life have persisted across evolutionary time, representing a through line that binds all mammals – including us. 

The findings come from the Zoonomia Project, an international effort that offers clues about human traits and diseases, animal abilities like hibernation and even the genetics behind a sled dog named Balto who helped save lives a century ago. 

Researchers shared some of their discoveries in 11 papers published Thursday in the journal Science. 

David O’Connor, who studies primate genetics at the University of Wisconsin-Madison, said the studies tackle deep questions. 

“It’s just the wonder of biology, how we are so similar and dissimilar to all the things around us,” said O’Connor, who wasn’t involved in the research. “It’s the sort of thing that reminds me why it’s cool to be a biologist.” 

The Zoonomia team, led by Elinor Karlsson and Kerstin Lindblad-Toh at the Broad Institute of MIT and Harvard, looked at 240 species of mammals, from bats to bison. They sequenced and compared their genomes — the instructions organisms need to develop and grow. 

They found that certain regions of these genomes have stayed the same across all mammal species over millions of years of evolution. 

One study found that at least 10% of the human genome is largely unchanged across species. Many of these regions occur outside the 1% of genes that give rise to proteins that control the activity of cells, the main purpose of DNA. 

Researchers theorized that long-preserved regions probably serve a purpose and are likely what they call “regulatory elements” containing instructions about where, when and how much protein is produced. Scientists identified more than 3 million of these in the human genome, about half of which were previously unknown. 

Scientists also focused on change within the animal kingdom. When they aligned genetic sequences for species and compared them with their ancestors, Karlsson said, they discovered that some species saw a lot of changes in relatively short periods of time. This showed how they were adapting to their environments. 

“One of the really cool things about mammals is that at this point in time, they’ve basically adapted to survive in nearly every single ecosystem on Earth,” Karlsson said. 

One group of scientists looked for genes that humans don’t have but other mammals do. 

Instead of focusing on new genes that might create uniquely human traits, “we kind of flipped that on its head,” said Steven Reilly, a genetics researcher at Yale University. 

“Losing pieces of DNA can actually generate new features,” Reilly said. 

For example, he said, a tiny DNA deletion between chimps and humans caused a cascade of changes in gene expression that may be one of the causes of prolonged brain development in humans. 

Another study focused on the fitness of one well-known animal: Balto. 

Scientists sequenced the genome of the sled dog, who led a team of dogs carrying a lifesaving diphtheria serum to Nome, Alaska, in 1925. His story was made into a 1995 animated feature film and a statue of the pup stands in New York’s Central Park. 

By comparing Balto’s genes to those of other dogs, researchers found he was more genetically diverse than modern breeds and may have carried genetic variants that helped him survive harsh conditions. One of the authors, researcher Katherine Moon of the University of California, Santa Cruz, said Balto “gives us this guide through comparative genomics,” showing how genetics can shape individuals. 

O’Connor said he expects Zoonomia to yield even more insights in the future. 

“To have these tools and to have the sort of audacity to ask these big questions” helps scientists and others “learn more about life around us,” he said.

Water may be more widespread and recent on Mars than previously thought, based on observations of Martian sand dunes by China’s rover. 

The finding highlights new, potentially fertile areas in the warmer regions of Mars where conditions might be suitable for life to exist, though more study is needed. 

Friday’s news came days after mission leaders acknowledged that the Zhurong rover had yet to wake up since going into hibernation for the Martian winter nearly a year ago. 

Its solar panels are likely covered with dust, choking off its power source and possibly preventing the rover from operating again, said Zhang Rongqiao, the mission’s chief designer. 

Before Zhurong fell silent, it observed salt-rich dunes with cracks and crusts, which researchers said likely were mixed with melting morning frost or snow as recently as a few hundred thousand years ago. 

Their estimated date range for when the cracks and other dune features formed in Mars’ Utopia Planitia — a vast plain in the northern hemisphere — is sometime after 1.4 million to 400,000 years ago or even younger. 

Conditions during that period were similar to what they are now on Mars, with rivers and lakes dried up and no longer flowing as they did billions of years earlier. 

Studying the structure and chemical makeup of these dunes can provide insights into “the possibility of water activity” during this period, the Beijing-based team wrote in a study published in Science Advances. 

“We think it could be a small amount … no more than a film of water on the surface,” co-author Xiaoguang Qin of the Institute of Geology and Geophysics said in an email. 

The rover did not directly detect any water in the form of frost or ice. But Qin said computer simulations and observations by other spacecraft at Mars indicated that even nowadays at certain times of year, conditions could be suitable for water to appear. 

What’s notable about the study is how young the dunes are, said planetary scientist Frederic Schmidt at the University of Paris-Saclay, who was not part of the study. 

“This is clearly a new piece of science for this region,” he said in an email. 

Small pockets of water from thawing frost or snow, mixed with salt, likely resulted in the small cracks, hard crusty surfaces, loose particles and other dune features like depressions and ridges, the Chinese scientists said. They ruled out wind as a cause, as well as frost made of carbon dioxide, which makes up the bulk of Mars’ atmosphere. 

Martian frost has been observed since NASA’s 1970s Viking missions, but these light dustings of morning frost were thought to occur in certain locations under specific conditions. 

The rover has now provided “evidence that there may be a wider distribution of this process on Mars than previously identified,” said Trinity College Dublin’s Mary Bourke, an expert in Mars geology. 

However small this watery niche is, it could be important for identifying habitable environments, she added. 

Launched in 2020, the six-wheeled Zhurong — named after a fire god in Chinese mythology — arrived at Mars in 2021 and spent a year roaming around before going into hibernation last May. The rover operated longer than intended, traveling nearly 2,000 meters.

The discovery of DNA’s double helix structure 70 years ago opened up a world of new science — and also sparked disputes over who contributed what and who deserves credit.

Much of the controversy comes from a central idea: that James Watson and Francis Crick — the first to figure out DNA’s shape — stole data from a scientist named Rosalind Franklin.

Now, two historians are suggesting that while parts of that story are accurate — Watson and Crick did rely on research from Franklin and her lab without permission — Franklin was more a collaborator than just a victim.

In an opinion article published Tuesday in the journal Nature, the historians say the two different research teams were working in parallel toward solving the DNA puzzle and knew more about what the other team was doing than is widely believed.

“It’s much less dramatic,” said article author Matthew Cobb, a zoologist at the University of Manchester who is working on a biography of Crick. “It’s not a heist movie.”

Photograph 51

The story dates back to the 1950s, when scientists were still working out how DNA’s pieces fit together.

Watson and Crick were working on modeling DNA’s shape at Cambridge University. Meanwhile, Franklin — an expert in X-ray imaging — was studying the molecules at King’s College in London, along with a scientist named Maurice Wilkins.

It was there that Franklin captured the iconic Photograph 51, an X-ray image showing DNA’s crisscross shape.

Then, the story gets tricky. In the version that’s often told, Watson was able to look at Photograph 51 during a visit to Franklin’s lab. According to the story, Franklin hadn’t solved the structure, even months after making the image. But when Watson saw it, “he suddenly, instantly knew that it was a helix,” said author Nathaniel Comfort, a historian of medicine at Johns Hopkins University who is writing a biography of Watson.

At about the same time, the story goes, Crick also obtained a lab report that included Franklin’s data and used it without her consent.

And according to this story, these two “eureka moments” — both based on Franklin’s work — Watson and Crick “were able to go and solve the double helix in a few days,” Comfort said.

This “lore” came in part from Watson himself in his book “The Double Helix,” the historians say. But they suggest this was a “literary device” to make the story more exciting and understandable to lay readers.

After digging in Franklin’s archives, the historians found new details that they say challenge this simplistic narrative — and suggest that Franklin contributed more than just one photograph along the way.

The proof? A draft of a Time magazine article from the time, written “in consultation with Franklin” but never published, described the work on DNA’s structure as a joint effort between the two groups. And a letter from one of Franklin’s colleagues suggested Franklin knew her research was being shared with Crick, the authors said.

Taken together, this material suggests the four researchers were equal collaborators in the work, Comfort said. While there may have been tensions, the scientists were sharing their findings more openly — not snatching them in secret.

“She deserves to be remembered not as the victim of the double helix, but as an equal contributor to the solution of the structure,” the authors conclude.

Howard Markel, a historian of medicine at the University of Michigan, said he’s not convinced by the updated story.

Markel — who wrote a book about the double helix discovery — believes that Franklin got “ripped off” by the others and they cut her out in part because she was a Jewish woman in a male-dominated field.

Franklin’s work critical 

In the end, Franklin left her DNA work behind and went on to make other important discoveries in virus research, before dying of cancer at age 37. Four years later, Watson, Crick and Wilkins received a Nobel prize for their work on DNA’s structure.

Franklin wasn’t included in that honor. Posthumous Nobel prizes have always been extremely rare, and now aren’t allowed.

What exactly happened, and in what order, will likely never be known for sure. Crick and Wilkins both died in 2004. Watson, 95, could not be reached, and Cold Spring Harbor Laboratory, where he served as director, declined to comment on the paper.

But researchers agree Franklin’s work was critical for helping unravel DNA’s double helix shape — no matter how the story unfolded.

“How should she be remembered?” asked Markel. “As a great scientist who was an equal contributor to the process. It should be called the Watson-Crick-Franklin model.”

The first thing 11-year-old Mia Rodriguez says she did with her new prosthetic hands was draw a picture of a kitten.

The Uruguayan girl, whose fingers never fully developed, put on the prosthetic hands and demonstrated the grasping movement she can now make.

“Now I can hold the pencil with one hand. Before, I had to do it with both hands because my fist wouldn’t close,” she said, while her mother, Ana Van López, watched excitedly.

Rodriguez received the prostheses from the Uruguayan Manos de Heroes foundation, which designs and prints hands and arms with 3D technology for children and adults across the South American country.

Since 2020, the foundation has provided more than 100 free prostheses, most of them for families in vulnerable situations.

Van Lopez, 28, lives with her partner and their four children in an abandoned factory in Salinas, about 40 kilometers (25 miles) from Montevideo, and her income comes from informal work such as selling firewood or pineapples. The family has a monthly income of about $200, or 8,000 pesos.

“I am very grateful; I thought my daughter was the only one with this problem. She had never come across someone like her in the hospital or on the street. It’s very difficult for us,” said Lopez, who is trying to obtain a state disability benefit for the girl equivalent to a little more than $380, or 15,000 pesos a month. In addition, they receive a similar amount of state support, she said.

Almost 16% of the Uruguayan population registers some level of disability, the majority mild, according to a 2011 census by the National Statistics Institute.

Rodriguez’s prosthetic hands move with threads that are taut from the motion of her wrists. They are violet with pink, colors she said she chose because they go well together, and are decorated with unicorn decals. Other children prefer the colors of their favorite soccer club or superhero.

The prostheses can be mechanical or electronic. They are placed on the hands, forearm, elbow or shoulder, according to the needs of each person.

Designing a hand, printing it and putting it together takes a couple of weeks, said Andrea Cukerman, an electrical engineer and founder of Manos de Heroes, or Hands of Heroes.

The prostheses are free, and the foundation is financed with contributions from private companies and donations. In Europe, a prosthetic hand with much more advanced technology can cost as much as $100,000, the foundation said.

On one of the walls of the foundation’s office there are photos of children and adults who have received prostheses. The images show children striking poses with hands and arms in vibrant colors — orange, green — or like those of Spider-Man.

“The idea is that they don’t feel alone,” Cukerman said.

The photos of adults are more subdued; most of their prostheses imitate the color and details of the skin.

Cukerman shows the prostheses she is currently printing: the arm of an adult who had an accident.

The day of the test, Rodriguez kept looking at everything in front of her, Cukerman recalled.

“When we showed her her hands, her face lit up, her big eyes, she hardly spoke,” she said.

They explained how the prosthetic hands worked, what movement she had to make to open and close her fist, and warned that some adjustments might have to be made.

Rodriguez put her hands on and began to try movements.

“It took a few seconds; they were perfect,” said her mother.

U.S. cigarette smoking dropped to another all-time low last year, with 1 in 9 adults saying they were current smokers, according to government survey data released Thursday. Meanwhile, electronic cigarette use rose, to about 1 in 17 adults.

The preliminary findings from the Centers for Disease Control and Prevention are based on survey responses from more than 27,000 adults.

Cigarette smoking is a risk factor for lung cancer, heart disease and stroke, and it’s long been considered the leading cause of preventable death.

In the mid-1960s, 42% of U.S. adults were smokers. The rate has been gradually dropping for decades, due to cigarette taxes, tobacco product price hikes, smoking bans and changes in the social acceptability of lighting up in public.

Last year, the percentage of adult smokers dropped to about 11%, down from about 12.5% in 2020 and 2021. The survey findings sometimes are revised after further analysis, and CDC is expected to release final 2021 data soon.

E-cigarette use rose to nearly 6% last year, from about 4.5% the year before, according to survey data.

The rise in e-cigarette use concerns Dr. Jonathan Samet, dean of the Colorado School of Public Health. Nicotine addiction has its own health implications, including risk of high blood pressure and a narrowing of the arteries, according to the American Heart Association.

“I think that smoking will continue to ebb downwards, but whether the prevalence of nicotine addiction will drop, given the rise of electronic products, is not clear,” said Samet, who has been a contributing author to U.S. Surgeon General reports on smoking and health for almost four decades.

Smoking and vaping rates are almost reversed for teens. Only about 2% of high school students were smoking traditional cigarettes last year, but about 14% were using e-cigarettes, according to other CDC data.
