Kourou, France — Europe’s new Ariane 6 rocket successfully blasted off for the first time on Tuesday, releasing satellites into orbit and restoring the continent’s independent access to space.

European space efforts have suffered a series of blows, including four years of delays on Ariane 6, that have robbed the continent of its own way to launch missions into space for the past year. 

But with the successful inaugural flight of Europe’s most powerful rocket yet, European space chiefs were keen to move on from recent setbacks. 

“It’s a historic day for Europe,” European Space Agency head Josef Aschbacher said.  

“Europe is back,” announced Philippe Baptiste, head of France’s CNES space agency. 

Surrounded by jungle on the South American coast, the rocket launched from Europe’s spaceport in Kourou, French Guiana at 4 p.m. local time (1900 GMT). 

The crew in the Jupiter control room, located 17 kilometers from the launch site, portrayed calm. 

Then head of operations Raymond Boyce announced, “propulsion nominal,” meaning that the launch was going as planned. 

Applause rang out in the room. 

Even louder applause came a little over an hour later, when the rocket successfully delivered microsatellites into orbit. 

NASA chief Bill Nelson on X welcomed the “giant leap forward” for the ESA. 

But Martin Sion, the CEO of the rocket’s manufacturer ArianeGroup, emphasized that “the mission is not yet complete.” 

It will only be fully completed when the reusable Vinci engine in the rocket’s upper stage has fallen back into Earth’s atmosphere. 

This is expected around three hours after liftoff. 

Since the last flight of its workhorse predecessor, Ariane 5, a year ago, Europe has had to rely on rivals such as Elon Musk’s U.S. firm SpaceX. 

Ariane 6 will be able to place satellites in geostationary orbit 36,000 kilometers (22,369.36 miles) above Earth, as well as satellite constellations a few hundreds of kilometers up. 

The first flight was carrying a payload of university microsatellites, various experiments and two atmospheric re-entry capsules that will be jettisoned near the end of the mission. 

The last of three ignitions of the Vinci engine will be to shoot the Vinci engine back down into the Pacific Ocean, so it does not contribute to the space debris cluttering Earth’s orbit. 

After months of analyzing the rocket’s inaugural launch, a first commercial flight is expected before the end of the year. 

The next challenge will be to “successfully ramp up” the number of flights, ESA space transportation director Toni Tolker-Nielsen said. 

Six launches are scheduled for next year, and eight for 2026.

New York — Purdue Pharma on Tuesday received U.S. court approval for a 60-day freeze on lawsuits against its owners — members of the wealthy Sackler family — in its first court appearance since a landmark U.S. Supreme Court ruling upended its bankruptcy settlement.  

U.S. Bankruptcy Judge Sean Lane granted an injunction at a court hearing in White Plains, New York, saying that a litigation cease-fire will give Purdue a chance to renegotiate a comprehensive settlement of lawsuits alleging that its painkiller OxyContin spurred an opioid addiction crisis in the U.S.  

The U.S. Supreme Court ruled on June 27 that Purdue Pharma’s bankruptcy settlement cannot shield the Sacklers, who did not file for bankruptcy themselves, over their role in the nation’s deadly opioid epidemic. 

The ruling sent Purdue back to the drawing board after nearly five years in bankruptcy and imperils billions of dollars in funding that the company and the Sacklers had promised to pay toward addressing the harms from the crisis. 

Lawsuits against Purdue and Sackler family members by state and local governments, as well as by individual plaintiffs, have accused them of fueling the opioid crisis through deceptive marketing of its pain medication. The company pleaded guilty to misbranding and fraud charges related to its marketing of OxyContin in 2007 and 2020.  

Purdue’s bankruptcy has stopped the opioid lawsuits from proceeding against the Stamford, Connecticut-based drugmaker since 2019, and Purdue has extended that legal protection to the Sacklers, as well. 

Purdue’s attorney, Marshall Huebner, said the company will engage in “a high-speed, high-stakes mediation” with the Sacklers, state and local governments and other stakeholders. Protecting the Sacklers during a “modest” 60-day negotiating period will give Purdue a real chance to negotiate a new bankruptcy settlement and put money toward stopping opioid overdoses and treating addiction, Huebner said. 

“Every single day of delay continues to come at a tragic, tragic cost,” Huebner said. 

Several stakeholders expressed hope for a settlement but said mediation should not be extended beyond the 60-day schedule proposed by Purdue. 

“It is essential to all parties in this case that we bring this five-year Chapter 11 case to a conclusion,” said Kenneth Eckstein, an attorney representing a coalition of state and local governments.  

During the hearing, Lane also appointed two mediators to aid settlement talks, including retired bankruptcy judge Shelley Chapman, who brokered a previous deal under which the Sacklers agreed to pay up to $6 billion to settle the opioid lawsuits. Eric Green will serve as the other mediator.  

If mediation fails, Purdue has said a court-appointed committee representing its creditors should be allowed to sue the Sacklers over claims they drained more thabn $11 billion from the company and that their conduct made Purdue liable for other lawsuits. 

The Sacklers have said the creditors’ proposed litigation is counterproductive and based on “factual errors.” Members of the family have denied wrongdoing and would fiercely oppose any litigation if the settlement talks break down, their attorneys said.  

“No one is assured of a recovery in this court or any other court,” said Gerard Uzzi, an attorney representing members of the Sackler family.  

Purdue’s previous bankruptcy settlement was supported by attorneys general from all 50 states, local governments and most of the individual opioid victims who voted on it.  

But it has also had detractors such as Carrie McGaha, who has had repeated overdoses and said Tuesday that individuals have been placed at the “bottom of the heap” throughout Purdue’s bankruptcy.

OKLAHOMA CITY, oklahoma — Former Senator Jim Inhofe, a conservative known for his strong support of defense spending and his denial that human activity is responsible for the bulk of climate change, has died. He was 89. 

Inhofe, a powerful fixture in Oklahoma politics for more than six decades, died Tuesday morning after suffering a stroke during the July Fourth holiday, his family said in a statement. 

Inhofe, a Republican who underwent quadruple bypass heart surgery in 2013 before being elected to a fourth term, was elected to a fifth Senate term in 2020, before stepping down in early 2023. 

‘The greatest hoax’

Inhofe frequently criticized the mainstream science that human activity contributed to changes in the Earth’s climate, once calling it “the greatest hoax ever perpetrated on the American people.” 

In February 2015, with temperatures in the nation’s capital below freezing, Inhofe brought a snowball on to the Senate floor. He tossed it before claiming that environmentalists focus attention on global warming as it kept getting cold. 

As Oklahoma’s senior U.S. senator, Inhofe was a staunch supporter of the state’s five military installations and a vocal fan of congressional earmarks. The Army veteran and licensed pilot, who would fly himself to and from Washington, secured the federal money to fund local road and bridge projects, and criticized House Republicans who wanted a one-year moratorium on such pet projects in 2010. 

“Defeating an earmark doesn’t save a nickel,” Inhofe told the Oklahoma City Chamber of Commerce that August. “It merely means that within the budget process, it goes right back to the bureaucracy.” 

He was a strong backer of President Donald Trump, who praised him for his “incredible support of our #MAGA agenda” while endorsing the senator’s 2020 reelection bid. During the Trump administration, Inhofe served as chair of the Senate Armed Services Committee following the death of Republican Senator John McCain of Arizona. 

Closer to home, Inhofe helped secure millions of dollars to clean up a former mining hub in northeast Oklahoma that spent decades on the Environmental Protection Agency’s Superfund list. In a massive buyout program, the federal government purchased homes and businesses within the 104-square-kilometer region of Tar Creek, where children consistently tested for dangerous levels of lead in their blood. 

Republican U.S. Representative Frank Lucas, the senior member of the Oklahoma congressional delegation, called Inhofe a true public servant. 

“His long career in the United States House and Senate serves as a testament to his strong moral compass and innate desire to better his home state,” Lucas said in a statement 

In 2021, Inhofe defied some in his party by voting to certify Democrat Joe Biden’s victory in the presidential election, saying that to do otherwise would be a violation of his oath of office to support and defend the Constitution. He voted against convicting Trump at both of his impeachment trials. 

Worked in business, public service

Born James Mountain Inhofe on Nov. 17, 1934, in Des Moines, Iowa, Inhofe grew up in Tulsa, Oklahoma, and received a bachelor’s degree in economics from the University of Tulsa in 1959. He served in the Army between 1956 and 1958 and was a businessman for three decades. 

He was elected to the state House in 1966 and two years later to the state Senate, where he remained during unsuccessful runs for governor in 1974 and for the U.S. House in 1976. He then won three terms as Tulsa mayor starting in 1978. 

Inhofe went on to win two terms in the U.S. House in the 1980s, before throwing his hat into a bitter U.S. Senate race when longtime Senator David Boren resigned in 1994 to become president of the University of Oklahoma. Inhofe beat then-U.S. Representive Dave McCurdy in a special election to serve the final two years of Boren’s term and was reelected five times. 

Boren, a Democrat, said he and Inhofe worked together in a bipartisan manner when both were in the state Legislature. He later defeated Inhofe in a race for governor. 

“While we ran against each other for governor, we were opponents but never enemies and remained friends,” Boren said in a statement. “I hope we can rebuild that spirit in American politics.” 

Frequent flyer

Inhofe was a commercial-rated pilot and flight instructor with more than 50 years of flying experience. 

He made an emergency landing in Claremore in 1999, after his plane lost a propeller, an incident later blamed on an installation error. In 2006, his plane spun out of control upon landing in Tulsa; he and an aide escaped injury, though the plane was badly damaged. 

In 2010, Inhofe landed his small plane on a closed runway at a rural South Texas airport while flying himself and others to South Padre Island. Runway workers scrambled, and Inhofe agreed to complete a remedial training program rather than face possible legal action. 

He later sponsored legislation that expanded the rights of pilots when dealing with Federal Aviation Administration disciplinary proceedings. 

Inhofe is survived by his wife, Kay, three children and several grandchildren. A son, Dr. Perry Dyson Inhofe II, died in November 2013, at the age of 51, when the twin-engine aircraft he was flying crashed a few miles north of Tulsa International Airport.

Abuja — In Nigeria, bushmeat is more than just food, it’s a culinary tradition and a trade. Despite the risk of zoonotic diseases like Ebola and Lassa fever, 45% of the country consumes bushmeat regularly, and now discussions to raise awareness are taking center stage.

Following last week’s World Zoonoses Day celebrations, Nigeria’s bush meat consumption comes under scrutiny due to the associated health risks.

Abuja-based civil servant Barnabas Bagudu among the 45% of Nigerians who consume bushmeat frequently, despite being aware of the potential risks. His personal favorites include antelope, rabbit, grasscutter, and alligator.

Bagudu emphasizes bushmeat’s unique taste and cultural significance.

“I like bushmeat so much that if I see it anywhere, I like to eat it, mostly antelope and rabbit. Since it is from bush, it’s blessed by God naturally, more than the one that we trained at home,” he said.

Bushmeat is also a thriving trade for many, like Evelyn Agbo, a seller of various types of bushmeat for over a decade.

She draws a huge patronage across Abuja, Nigeria’s capital, with antelope being her bestseller.

Agbo explains the preparation process.

“When I get the bushmeat, I dress it with salt and heat over fire with firewood until it is dried. I could do this for two days because if it’s not dry, flies will perch on it and attract diseases,” she said. 

The World Health Organization states that about 60% of all infectious diseases are zoonotic, passing from animals to humans.

Nigeria has a high prevalence of zoonotic pathogens like Ebola, tuberculosis, and Lassa fever.

Abuja-based public health expert Ejike Orij warns about bushmeat consumption amid a fragile healthcare system.

“So, if for any reason that animal is infected and then it is now killed and served to humans in bats and in restaurant, that’s how the transmission starts,” he said.

The theme of the 2024 World Zoonoses Day was awareness and prevention of zoonotic diseases.

In Nigeria, efforts to promote safer bushmeat consumption practices remain low.

Orji stresses the need to ramp up awareness.

“There has been a lot of public education and community engagement by government on the issue of bushmeat, especially when there was an epidemic of lassa fever…it’s just to spread the awareness especially to the people who prepare it,” he said.

While bushmeat is a top delicacy in Nigeria, the need for safer consumption practices is urgent.

Public health experts urge Nigerians to explore domestic protein sources like chicken and to increase public awareness to mitigate risks.

LIMA, Peru — The preserved body of an American mountaineer — who disappeared 22 years ago while scaling a snowy peak in Peru — has been found after being exposed by climate change-induced ice melt, police said Monday.

William Stampfl was reported missing in June 2002, aged 59, when an avalanche buried his climbing party on the mountain Huascaran, which stands more than 6,700 meters (22,000 feet) high. Search and rescue efforts were fruitless.

Peruvian police said his remains were finally exposed by ice melt on the Cordillera Blanca range of the Andes.

Stampfl’s body, as well as his clothes, harness and boots had been well-preserved by the cold, according to images distributed by the police.

His passport was found among his possessions in good condition, allowing police to identify the body.

The mountains of northeastern Peru, home to snowy peaks such as Huascaran and Cashan, are a favorite with mountaineers from around the world.

In May, the body of an Israeli hiker was found there nearly a month after he disappeared.

And last month, an experienced Italian mountaineer was found dead after he fell while trying to scale another Andean peak.

Harare, Zimbabwe — After her son, the family’s shining light and only breadwinner, was arrested last year, Tambudzai Tembo went into meltdown. In Zimbabwe, where clinical mental health services are scarce, her chances of getting professional help were next to zero. She contemplated suicide.

“I didn’t want to live anymore. People who saw me would think everything was OK. But inside, my head was spinning,” the 57-year-old said. “I was on my own.”

A wooden bench and an empathetic grandmother saved her.

Older people are at the center of a homegrown form of mental health therapy in Zimbabwe that is now being adopted in places like the United States.

The approach involves setting up benches in quiet, discreet corners of community clinics and in some churches, poor neighborhoods and at a university. An older woman with basic training in problem-solving therapy patiently sits there, ready to listen and engage in a one-on-one conversation.

The therapy is inspired by traditional practice in Zimbabwe in which grandmothers were the go-to people for wisdom in rough times. It had been abandoned with urbanization, the breakdown of tight-knit extended families and modern technology. Now it is proving useful again as mental health needs grow.

“Grandmothers are the custodians of local culture and wisdom. They are rooted in their communities,” said Dixon Chibanda, a psychiatry professor and founder of the initiative.

“They don’t leave, and in addition, they have an amazing ability to use what we call ‘expressed empathy’… to make people feel respected and understood.”

Last year, Chibanda was named the winner of a $150,000 prize by the U.S.-based McNulty Foundation for revolutionizing mental healthcare. Chibanda said the concept has taken root in parts of Vietnam, Botswana, Malawi, Kenya and Tanzania and is in “preliminary formative work” in London.

In New York, the city’s new mental health plan launched last year says it is “drawing inspiration” from what it calls the Friendship Bench to help address risk factors such as social isolation. The orange benches are now in areas including Harlem, Brooklyn and the Bronx.

In Washington, the organization HelpAge USA is piloting the concept under the DC Grandparents for Mental Health initiative, which started in 2022 as a COVID-19 support group of people 60 and above.

So far, 20 grandmothers have been trained by a team from Friendship Bench Zimbabwe to listen, empathize and empower others to solve their problems, said Cindy Cox-Roman, the president and chief executive of HelpAge USA.

Benches will be set up at places of worship, schools and wellness centers in Washington’s low-income communities with people who “have been historically marginalized and more likely to experience mental health problems,” she said.

Cox-Roman cited fear and distrust in the medical system, lack of social support and stigma as some of the factors limiting access to treatment.

“People are hurting, and a grandmother can always make you feel better,” she said.

More than one in five U.S. adults live with a mental illness, according to the National Institute of Mental Health.

“The mental health crisis is real. Where it’s a real crisis after the pandemic is that many clinicians have dropped out of the workforce,” said Dr. Jehan El-Mayoumi, who works as an expert with HelpAge USA and is a founding director of the health equity Rodham Institute at Georgetown University. She has struggled to get psychiatrists for acutely suicidal patients.

El-Mayoumi said the Zimbabwean concept provides people with “someone you can trust, open up your heart to, that you can tell your deepest secrets [and] that requires trust, so that’s what’s so wonderful about the Friendship Bench.”

The idea was born out of tragedy. Chibanda was a young psychiatrist, and one of just over 10 in Zimbabwe in 2005. One of his patients desperately wanted to see him, but she could not afford the $15 bus fare. Chibanda later learned that she had killed herself.

“I realized that I needed to have a stronger presence in the community,” Chibanda said. “I realized that actually one of the most valuable resources are these grandmothers, the custodians of local culture.”

He recruited 14 grandmothers in the neighborhood near the hospital where he worked in the capital, Harare, and trained them. In Zimbabwe, they get $25 a month to help with transport and phone bills.

The network, which now partners with the health ministry and the World Health Organization, has grown to over 2,000 grandmothers across the country. Over 200,000 Zimbabweans sat on a bench to get therapy from a trained grandmother in 2023, according to the network.

Siridzayi Dzukwa, the grandmother who talked Tembo out of suicide, made a home follow-up visit on a recent day. Using a written questionnaire, she checked on Tembo’s progress. She listened as Tembo talked about how she has found a new lease on life and now sells vegetables to make ends meet.

Dzukwa has become a recognizable figure in the area. People stop to greet and thank her for helping them. Some ask for a home visit or take down her number.

“People are no longer ashamed or afraid of openly stopping us on the streets and ask us to talk,” she said. “Mental health is no longer something to be ashamed of.”

Las Vegas — Roughly 130 million people were under threat over the weekend and into next week from a long-running heat wave that broke or tied records with dangerously high temperatures and is expected to shatter more from East Coast to West Coast, forecasters said.

Ukiah, north of San Francisco, hit 117 degrees Fahrenheit (47 degrees Celsius) on Saturday, breaking the city’s record for the date and tying its all-time high. Livermore, east of San Francisco, hit 111 F (43.8 C), breaking the daily maximum temperature record of 109 F (42.7 C) set more than a century ago in 1905.

Las Vegas tied the record of 115 F (46 C), last reached in 2007, and Phoenix topped out at 114 F (45.5 C), just shy of the record of 116 F (46.7 C) dating to 1942.

The National Weather Service said it was extending the excessive heat warning for much of the Southwest through Friday.

“A dangerous and historic heatwave is just getting started across the area, with temperatures expected to peak during the Sunday-Wednesday timeframe,” the National Weather Service in Las Vegas said in an updated forecast.

In Las Vegas, where the mercury hit 100 F (37.7 C) by 10:30 a.m., Marko Boscovich said the best way to beat the heat is in a seat at a slot machine with a cold beer inside an air-conditioned casino.

“But you know, after it hits triple digits it’s about all the same to me,” said Boscovich, who was visiting from Sparks, Nevada to see a Dead & Company concert Saturday night at the Sphere. “Maybe they’ll play one of my favorites — ‘Cold Rain and Snow.’”

In more humid parts of the country, temperatures could spike above 100 F (about 38 C) in parts of the Pacific Northwest, the mid-Atlantic and the Northeast, said Jacob Asherman, a weather service meteorologist.

Heat records shattered across the Southwest

Meteorologists predicted that temperatures would be near daily records in the region through most, if not all, of the coming week, with lower desert highs reaching 115 to 120 degrees F (46.1 to 48.8 C).

Rare heat advisories were extended even into higher elevations including around Lake Tahoe, on the border of California and Nevada, with the National Weather Service in Reno, Nevada, warning of “major heat risk impacts, even in the mountains.”

“How hot are we talking? Well, high temperatures across (western Nevada and northeastern California) won’t get below 100 degrees (37.8 C) until next weekend,” the service posted online. “And unfortunately, there won’t be much relief overnight either.”

Indeed, Reno hit a high of 104 F (40 C) on Saturday, smashing the old record of 101 F (38.3 C).

More extreme highs are in the near forecast, including 129 F (53.8 C) for Sunday at Furnace Creek, California, in Death Valley National Park, and then around 130 F (54.4 C) through Wednesday.

The hottest temperature ever officially recorded on Earth was 134 F (56.67 C) in July 1913 in Death Valley, eastern California, though some experts dispute that measurement and say the real record was 130 F (54.4 C), recorded there in July 2021.

The worst is yet to come across the West and mid-Atlantic

Triple-digit temperatures are likely in the West, between 15 and 30 F (8 and 16 C) higher than average into next week, the National Weather Service said.

The Eastern U.S. also was bracing for more hot temperatures. Baltimore and others parts of Maryland were under an excessive heat warning as heat index values could climb to 110 F (43 C), forecasters said.

“Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors,” read a National Weather Service advisory for the Baltimore area. “Young children and pets should never be left unattended in vehicles under any circumstances.”

Deaths are starting to mount

In Arizona’s Maricopa County, which encompasses Phoenix, there have been at least 13 confirmed heat-related deaths this year, along with more than 160 other deaths suspected of being related to heat that are still under investigation, according to a recent report.

That does not include the death of a 10-year-old boy last week in Phoenix who suffered a “heat-related medical event” while hiking with family at South Mountain Park and Preserve, according to police.

California wildfires fanned by low humidity, high temperatures

Firefighters dispatched aircraft and helicopters to drop water or retardant on a series of wildfires in California.

In Santa Barbara County, northwest of Los Angeles, the Lake Fire has scorched more than 19 square miles (49 square kilometers) of grass, brush and timber. Firefighters said the blaze was displaying “extreme fire behavior” and had the “potential for large growth” with high temperatures and low humidity.

Festival revelers meet the heat with cold water and shade

At the Waterfront Blues Festival in Portland, Oregon, music fans coped by drinking cold water, seeking shade or freshening up under water misters. Organizers of the weekend revelries also advertised free access to air conditioning in a nearby hotel.

Angelica Quiroz, 31, kept her scarf and hat wet and applied sunscreen.

“Definitely a difference between the shade and the sun,” Quiroz said Friday. “But when you’re in the sun, it feels like you’re cooking.”

CAPE TOWN, South Africa — Scientists in South Africa have been stunned to discover that termite mounds that are still inhabited in an arid region of the country are more than 30,000 years old, meaning they are the oldest known active termite hills.

Some of the mounds near the Buffels River in Namaqualand were estimated by radiocarbon dating to be 34,000 years old, according to the researchers from Stellenbosch University.

“We knew they were old, but not that old,” said Michele Francis, senior lecturer in the university’s department of soil science who led the study. Her paper was published in May.

Francis said the mounds existed while saber-toothed cats and woolly mammoths roamed other parts of the Earth and large swathes of Europe and Asia were covered in ice. They predate some of the earliest cave paintings in Europe.

Some fossilized termite mounds have been discovered dating back millions of years. The oldest inhabited mounds before this study were found in Brazil and are around 4,000 years old. They are visible from space.

Francis said the Namaqualand mounds are a termite version of an “apartment complex” and the evidence shows they have been consistently inhabited by termite colonies.

Termite mounds are a famous feature of the Namaqualand landscape, but no one suspected their age until samples of them were taken to experts in Hungary for radiocarbon dating.

“People don’t know that these are special, ancient landscapes that are preserved there,” Francis said.

Some of the biggest mounds — known locally as “heuweltjies,” which means little hills in the Afrikaans language — measure around 30 meters across. The termite nests are as deep as 3 meters underground.

Researchers needed to carefully excavate parts of the mounds to take samples, and the termites went into “emergency mode” and started filling in the holes, Francis said.

The team fully reconstructed the mounds to keep the termites safe from predators like aardvarks.

Francis said the project was more than just a fascinating look at ancient structures. It also offered a peek into a prehistoric climate that showed Namaqualand was a much wetter place when the mounds were formed.

The southern harvester termites are experts at capturing and storing carbon by collecting twigs and other dead wood and putting it back deep into the soil. That has benefits in offsetting climate change by reducing the amount of carbon emitted into the atmosphere.

It’s also good for the soil. Masses of wildflowers bloom on top of the termite mounds in a region that receives little rain.

Francis called for more research on termite mounds given the lessons they offer on climate change, sustaining ecosystems and maybe even for improving agricultural practices.

“We will do well to study what the termites have done in the mounds. They were thought to be very boring,” she said.

WASHINGTON — Scientists have revealed fossils of a giant salamanderlike beast with sharp fangs that ruled waters before the first dinosaurs arrived.

The predator, which was larger than a person, likely used its wide, flat head and front teeth to suck in and chomp unsuspecting prey, researchers said. Its skull was about 60 centimeters (2 feet) long.

“It’s acting like an aggressive stapler,” said Michael Coates, a biologist at the University of Chicago who was not involved with the work.

Fossil remnants of four creatures collected about a decade ago were analyzed, including a partial skull and backbone. The findings on Gaiasia jennyae were published Wednesday in the journal Nature. The creature existed some 40 million years before dinosaurs evolved.

Researchers have long examined such ancient predators to uncover the origins of tetrapods: four-legged animals that clambered onto land with fingers instead of fins and evolved to amphibians, birds and mammals including humans.

Most early tetrapod fossils hail from hot, prehistoric coal swamps along the equator in what’s now North America and Europe. But these latest remnants, dating back to about 280 million years ago, were found in modern-day Namibia, an area in Africa that was once encrusted with glaciers and ice.

That means tetrapods may have thrived in colder climates earlier than scientists expected, prompting more questions about how and when they took over the Earth.

“The early story of the first tetrapods is much more complex than we thought,” said co-author Claudia Marsicano at the University of Buenos Aires, who was part of the research.

The creature’s name comes from the Gai-As rock formation in Namibia where the fossils were found and for the late paleontologist Jennifer Clack, who studied how tetrapods evolved.

washington — The NASA astronaut knocks loudly three times on what appears to be a nondescript door and calls cheerfully: “You ready to come out?” 

The reply is inaudible, but beneath his mask he appears to be grinning as he yanks the door open, and four scientists who have spent a year away from all other human contact, simulating a mission to Mars, spill out to cheers and applause. 

Anca Selariu, Ross Brockwell, Nathan Jones and team leader Kelly Haston have spent the past 378 days sealed inside the “Martian” habitat in Houston, Texas, part of NASA’s research into what it will take to put humans on the Red Planet.  

They have been growing vegetables, conducting “Marswalks,” and operating under what NASA terms “additional stressors,” such as communication delays with “Earth,” including their families; isolation and confinement.  

It’s the kind of experience that would make anyone who lived through pandemic lockdowns shudder, but all four were beaming as they reemerged Saturday, their hair slightly more unruly and their emotion apparent.  

“Hello. It’s actually so wonderful just to be able to say hello to you,” Haston, a biologist, said with a laugh. 

“I really hope I don’t cry standing up here in front of all of you,” Jones, an emergency room doctor, said as he took to the microphone, and nearly doing just that several moments later as he spotted his wife in the crowd.  

The habitat, dubbed Mars Dune Alpha, is a 3D-printed, 160-square-meter facility, complete with bedrooms, a gym, common areas, and a vertical farm for growing food. 

An outdoor area, separated by an airlock, is filled with red sand and is where the team donned suits to conduct their “Marswalks,” though it is still covered rather than being open air. 

“They have spent more than a year in this habitat conducting crucial science, most of it nutrition-based and how that impacts their performance … as we prepare to send people on to the Red Planet,” Steve Koerner told the crowd. Koerner is the deputy director at NASA’s Johnson Space Center. 

“I’m very appreciative,” he added. 

This mission is the first of a series of three planned by NASA, grouped under the title CHAPEA — Crew Health and Performance Exploration Analog. 

A yearlong mission simulating life on Mars took place in 2015-2016 in a habitat in Hawaii, and although NASA participated in it, it was not at the helm. 

Under its Artemis program, America plans to send humans back to the Moon to learn how to live there long-term to help prepare a trip to Mars, sometime towards the end of the 2030s.

portland, oregon — Roughly 130 million people were under threat Saturday and into next week from a long-running heat wave that already has broken records with dangerously high temperatures — and is expected to shatter more from East Coast to West Coast, forecasters said.

Oppressive heat and humidity could team up to spike temperatures above 100 degrees Fahrenheit (about 38 degrees Celsius) in parts of the Pacific Northwest, the Mid-Atlantic and the Northeast, said Jacob Asherman, a meteorologist with the National Weather Service.

In Oregon, records could be broken in cities including Eugene, Portland and Salem, Asherman said. Dozens of other records throughout the U.S. could fall, Asherman added, causing millions to seek relief from the blanket of heat in cooling centers from Bullhead City, Arizona, to Norfolk, Virginia.

The National Weather Service said Saturday it was extending the excessive heat warning for much of the Southwest into Friday.

“A dangerous and historic heatwave is just getting started across the area, with temperatures expected to peak during the Sunday-Wednesday timeframe,” the National Weather Service in Las Vegas, Nevada, said in an updated forecast.

Excessive heat will likely continue through Friday, the service said.

In sweltering Las Vegas, where the temperature hit 100 F (37.7 C) by 10:30 a.m., Marko Boscovich said the best way to beat the heat is in a seat at a slot machine with a cold beer inside an air-conditioned casino.

“But you know, after it hits triple digits it’s about all the same to me,” said Boscovich, who was visiting from Sparks, Nevada, to see a Dead & Company concert later Saturday night at the Sphere. “Maybe they’ll play one of my favorites — ‘Cold Rain and Snow.'”

Heat records shatter

By 10:30 a.m. Saturday, the National Weather Service said the temperature already had risen to 100 F (36.6 C) in Phoenix, which saw a record high of 118 F (47.7 C) for Friday.

Meteorologists predict temperatures will be near daily records region-wide through most, if not all, of the coming week with lower desert highs reaching 115 to 120 F (46.1 to 48.8 C).

Rare heat advisories had been extended even into the upper elevations, including around Lake Tahoe on the California-Nevada border. The National Weather Service in Reno, Nevada, warned of “major heat risk impacts, even in the mountains.”

“How hot are we talking? Well, high temperatures across (western Nevada and northeastern California) won’t get below 100 degrees (37.8 C) until next weekend,” the service posted online. “And unfortunately, there won’t be much relief overnight either.”

A new heat record for the day was set Friday in California’s Death Valley — one of the hottest places on Earth — with the mercury climbing to 127 F (52.8 C). The old mark of 122 F (50 C) was last tied in 2013.

Palm Springs, California, hit 124 F (51.1 C) Friday, breaking the city’s record of 123 F (50.5 C).

More extreme highs are in the near forecast, including 129 F (53.8 degrees C) for Sunday at Furnace Creek in Death Valley National Park, and then around 130 (54.4 C) through Wednesday. The hottest temperature ever officially recorded on Earth was 134 degrees (56.67 C) in Death Valley in July 1913, though some experts dispute that measurement and say the real record was 130 F (54.4 C) recorded there in July 2021.

Worst yet to come

The worst was yet to come across much of the West, with triple-digit temperatures likely higher than average into next week, the National Weather Service said.

The Eastern U.S. also was bracing for more hot temperatures. Baltimore and other parts of Maryland were under an excessive heat warning, as heat index values could climb to 110 F (43 C), forecasters said.

Heat leads to some deaths

In Arizona’s Maricopa County, which encompasses Phoenix, there have been at least 13 confirmed heat-related deaths this year, along with more than 160 other suspected heat deaths are still under investigation, according to the county’s most recent report.

That does not include the death of a 10-year-old boy this week in Phoenix who suffered a “heat-related medical event” while hiking with family at South Mountain Park and Preserve, according to police.

Lausanne, Switzerland — In the battle against drug use at the Paris Olympics, the International Testing Agency plans to deploy a more streamlined, high-tech approach to identify and target potential cheats.

In an interview with Agence France-Presse, Benjamin Cohen, director general of the ITA, said potential tools at its disposal included biological and performance passports as well as a mountain of other data.

Upgraded software, possibly using artificial intelligence, could also help; an investigative unit aided by whistleblowers was making inroads; and increased cooperation with sports bodies and police was bearing fruit.

The ITA, which was founded in 2018, runs the anti-doping program for the Olympics, the Tour de France and “more than 65 international organizations,” said Cohen.

The challenge was to refine the “risk analysis” and identify athletes to monitor using as little time and resources as possible, said Cohen, a Swiss lawyer who has headed the agency since its creation.

The problem is accentuated in the run-up to the Paris Games.

“We still have 30,000 potentially qualifying athletes and we cannot wait to have the final list to focus on the 11,000 participants,” Cohen said.

“Certain doping practices enable athletes to achieve results very quickly,” he said. “Traditionally the pre-Olympic period is high-risk time … the last moment to make a difference. Athletes know that they will be very closely monitored at the Olympics, so I would hope that very few, if any, will be tempted to take drugs in the Olympic Village in Paris.”

At the Games, only medalists are automatically tested, but the ITA wants to find ways to target potential dopers before the finish.

Cohen said the ITA tries to identify patterns. It looks at the demands of each discipline and the substances it might tempt athletes to use. Then the ITA looks at delegations and “the history of doping in that country.” Finally, it scrutinizes each individual athlete and “the development of his or her performances, any suspicious biological passport profiles, suspicious anti-doping tests and so on.”

“That’s hundreds of thousands of pieces of data.”

“Risk analysis”

“Today we have our own software, and the next stage” will involve “programming computers to extract this data, because we still do a lot of this work manually.”

After that, the ITA hopes to “seize all the opportunities offered by artificial intelligence,” provided “we use these new tools ethically.”

“If it’s done properly,” he said, “AI will enable us to go much further in risk analysis and prediction.”

The ITA is developing a “performance passport” as a counterpart to the long-established biological passport.

The objective is to “predict results on the basis of what an athlete has done over the last four years,” said Cohen.

“Artificial intelligence will enable us to say: ‘This is really an unusual result, which could suggest doping,'” he said. “It could help us flag them.”

The performance passport project was initially tested in swimming and weightlifting, two indoor sports in which athletes compete in identical environments each time.

Weightlifting also is one of the sports that have returned a vast number of positive tests at Summer Olympics.

In 2021, the ITA carried out “a major investigation into weightlifting,” and that enabled them to set up a specialized unit in cooperation with the sport.

Focus on cycling

It now has more than 10 such units. “Cycling is a particular focus,” but “other sports are beginning to understand the benefits of gathering intelligence, having anonymous sources and promoting whistleblowers.”

“It’s a new method that complements traditional testing.”

Cohen said the ITA has been working to build links with law enforcement and exploit “synergies.”

“They are bearing fruit,” he said, referring to the case of 23-year-old Italian cyclist Andrea Piccolo, arrested on June 21 by the Italian Carabinieri who caught him returning to the country with growth hormones.

“ITA asked the Italian authorities to open his luggage, which would not have been possible six years ago,” Cohen said.

“We carry out the controls, we monitor the performances of these athletes, we know the networks, the doctors involved and the drugs they are taking. And they can seize and open suitcases and enter hotel rooms.”
