pentagon — U.S. Army Colonel Frank Rubio, who holds the record for the longest U.S. spaceflight, recounted the “awesome” experience of re-entering Earth’s atmosphere on Thursday during a Pentagon ceremony honoring his achievement.

“Colonel Rubio is a stellar example of someone who has made the absolute most of every opportunity,” Army Secretary Christine Wormuth said as she presented him with an honor known as the Army Astronaut Device. “It’s truly a privilege to have him representing the Army and the United States.”

The Army awards the astronaut device to soldiers who complete at least one mission in space. Rubio joins Colonel Anne McClain and Colonel Andrew Morgan as the only active-duty soldiers authorized to wear it.

Rubio returned to Earth late last year on a Russian spacecraft after 371 days in the International Space Station.

The doctor and Black Hawk helicopter pilot flew more than 600 hours in dangerous combat deployments in Bosnia, Afghanistan and Iraq before joining NASA in 2017 to become an astronaut.

While becoming an astronaut is a childhood dream for many who go to space, Rubio said he fell in love with the space mission much later in life.

“It’s few things where you can say, ‘Hey, my job helps represent humanity.’ And that’s a pretty powerful thing to be a part of,” Rubio told reporters at the Pentagon.

While he now holds the record for longest spaceflight by an American, he certainly wasn’t trying to earn that title. Rubio’s six-month mission was extended to 371 days after his initial ride home sprang a leak.

His year in space led to incredible highlights, he said, from hurtling into space on top of 300 tons of rocket fuel during the launch, to spacewalks, to re-entering Earth’s atmosphere.

“You essentially become a meteorite, right, and you have a plasma layer a couple of inches below you, because of the heat that’s generated. All those things were awesome,” he said in response to a question from VOA.

Rubio is the son of Salvadoran immigrants, and he credits the Army for giving him the chance to reach for the stars.

“I think it is the American Dream. It really represents the fact that we have so many opportunities, and again, I really value the fact that it’s the opportunity that’s given, not the results,” he said. “And I think if you put in the hard work, if you dedicate yourself and you sacrifice, really almost anything is possible.”

Rubio told reporters on Thursday that he hopes to continue contributing to NASA’s mission on the ground and back in space.

montgomery, alabama — A second in vitro fertilization provider in the U.S. state of Alabama is pausing parts of its care to patients after the state Supreme Court ruled that frozen embryos are legally considered children. 

Alabama Fertility Services said in a statement Thursday that it has “made the impossibly difficult decision to hold new IVF treatments due to the legal risk to our clinic and our embryologists.” 

The decision comes a day after the University of Alabama at Birmingham health system said in a statement that it was pausing IVF treatments so it could evaluate whether its patients or doctors could face criminal charges or punitive damages. 

“We are contacting patients that will be affected today to find solutions for them and we are working as hard as we can to alert our legislators as to the far reaching negative impact of this ruling on the women of Alabama,” Alabama Fertility said. “AFS will not close. We will continue to fight for our patients and the families of Alabama.” 

Doctors and patients have been grappling with shock and fear this week as they try to determine what they can and can’t do after the ruling by the all-Republican Alabama Supreme Court that raises questions about the future of IVF. 

Alabama Fertility Services’ decision left Gabby Goidel, who was days from an expected egg retrieval, calling clinics across the South looking for a place to continue IVF care. 

“I freaked out. I started crying,” Goidel said. “I felt in an extreme limbo state,”

The Alabama ruling came down Friday, the same day Goidel began a 10-day series of injections ahead of egg retrieval, with the hopes of getting pregnant through IVF next month. She found a place in Texas that will continue her care and plans to travel there Thursday night. 

Goidel experienced three miscarriages and she and her husband turned to IVF as a way of fulfilling their dream of becoming parents. 

“It’s not pro-family in any way,” Goidel said of the Alabama ruling. 

Dr. Michael C. Allemand, a reproductive endocrinologist at Alabama Fertility, said Wednesday that IVF is often the best treatment for patients who desperately want a child, and the ruling threatens doctors’ ability to provide that care. 

“The moments that our patients are wanting to have by growing their families — Christmas mornings with grandparents, kindergarten, going in the first day of school, with little backpacks — all that stuff is what this is about. Those are the real moments that this ruling could deprive patients of,” he said. 

Justices — citing language in the Alabama Constitution that the state recognizes the “rights of the unborn child” — said three couples could sue for wrongful death when their frozen embryos were destroyed in an accident at a storage facility. 

“Unborn children are ‘children’ … without exception based on developmental stage, physical location, or any other ancillary characteristics,” Justice Jay Mitchell wrote in Friday’s majority ruling. Mitchell said the court had previously ruled that a fetus killed when a woman is pregnant is covered under Alabama’s Wrongful Death of a Minor Act and nothing excludes “extrauterine children from the Act’s coverage.” 

While the court case centered on whether embryos were covered under the wrongful death of a minor statute, some said treating the embryo as a child — rather than property — could have broader implications and call into question many of the practices of IVF.

WASHINGTON — Alzheimer’s quietly ravages the brain long before symptoms appear, and now scientists have new clues about the dominolike sequence of those changes — a potential window to one day intervene. 

A large study in China tracked middle-aged and older adults for 20 years, using regular brain scans, spinal taps and other tests. 

Compared to those who remained cognitively healthy, people who eventually developed the mind-robbing disease had higher levels of an Alzheimer’s-linked protein in their spinal fluid 18 years prior to diagnosis, researchers reported Wednesday. Then every few years afterward, the study detected another so-called biomarker of brewing trouble. 

Scientists don’t know exactly how Alzheimer’s forms. One early hallmark is that sticky protein called beta-amyloid, which over time builds up into brain-clogging plaques. Amyloid alone isn’t enough to damage memory — plenty of healthy people’s brains harbor a lot of plaque. An abnormal tau protein that forms neuron-killing tangles is one of several co-conspirators. 

The new research, published in The New England Journal of Medicine, offers a timeline for how those abnormalities pile up. 

The study’s importance “cannot be overstated,” said Dr. Richard Mayeux, an Alzheimer’s specialist at Columbia University who wasn’t involved in the research. 

“Knowledge of the timing of these physiological events is critical” for testing new ways of treating and maybe eventually even preventing Alzheimer’s, he wrote in an accompanying editorial. 

The findings have no practical implications yet. 

First treatment

More than 6 million Americans, and millions more worldwide, have Alzheimer’s, the most common form of dementia. There’s no cure. But last year, a drug named Leqembi became the first to be approved, with clear evidence that it could slow the worsening of early Alzheimer’s — albeit for a few months. 

It works by clearing away some of that gunky amyloid protein. The approach also is being tested to see if it’s possible to delay Alzheimer’s onset if high-risk people are treated before symptoms appear. Still, other drugs are being developed to target tau. 

Tracking silent brain changes is key for such research. Scientists already knew that in rare, inherited forms of Alzheimer’s that strike younger people, a toxic form of amyloid starts accumulating about two decades ahead of symptoms, and at some point later, tau kicks in. 

The new findings show the order in which such biomarker changes occurred with more common old-age Alzheimer’s. 

Researchers with Beijing’s Innovation Center for Neurological Disorders compared 648 people eventually diagnosed with Alzheimer’s and an equal number who remained healthy. The amyloid finding in future Alzheimer’s patients was the first, 18 years or 14 years prior to diagnosis depending on the test used. 

Differences in tau were detected next, followed by a marker of trouble in how neurons communicate. A few years after that, differences in brain shrinkage and cognitive test scores between the two groups became apparent, the study found. 

“The more we know about viable Alzheimer’s treatment targets and when to address them, the better and faster we will be able to develop new therapies and preventions,” said Claire Sexton, the Alzheimer’s Association’s senior director of scientific programs. She noted that blood tests are coming soon that promise to also help by making it easier to track amyloid and tau.

CAPE CANAVERAL, Fla. — A private U.S. lunar lander reached the moon and eased into a low orbit Wednesday, a day before it will attempt an even greater feat — landing on the gray, dusty surface.

A smooth touchdown would put the U.S. back in business on the moon for the first time since NASA astronauts closed out the Apollo program in 1972. The company, if successful, also would become the first private outfit to ace a moon landing.

Launched last week, Intuitive Machines’ lander fired its engine on the back side of the moon while out of contact with Earth. Flight controllers at the company’s Houston headquarters had to wait until the spacecraft emerged to learn whether the lander was in orbit or hurtling aimlessly away.

Intuitive Machines confirmed its lander, nicknamed Odysseus, was circling the moon with experiments from NASA and other clients. The lander is part of a NASA program to kickstart the lunar economy; the space agency is paying $118 million to get its experiments on the moon on this mission.

On Thursday, controllers will lower the orbit from just under 60 miles (92 kilometers) to 6 miles (10 kilometers) — a crucial maneuver occurring again on the moon’s far side — before aiming for a touchdown near the moon’s south pole. It’s a dicey place to land with all the craters and cliffs, but deemed prime real estate for astronauts since the permanently shadowed craters are believed to hold frozen water.

The moon is littered with wreckage from failed landings. Some missions never even got that far. Another U.S. company — Astrobotic Technology — tried to send a lander to the moon last month, but it didn’t get there because of a fuel leak. The crippled lander came crashing back through the atmosphere, burning up over the Pacific.

A rundown on the moon’s winners and losers:

First victories

The Soviet Union’s Luna 9 successfully touches down on the moon in 1966, after its predecessors crash or miss the moon altogether. The U.S. follows four months later with Surveyor 1. Both countries achieve more robotic landings, as the race heats up to land men.

Apollo rules

NASA clinches the space race with the Soviets in 1969 with a moon landing by Apollo 11’s Neil Armstrong and Buzz Aldrin. Twelve astronauts explore the surface over six missions, before the program ends with Apollo 17 in 1972. Still the only country to send humans to the moon, the U.S. hopes to return crews to the surface by the end of 2026 or so, a year after a lunar fly-around by astronauts.

China emerges

China, in 2013, becomes the third country to successfully land on the moon, delivering a rover named Yutu, Chinese for jade rabbit. China follows with the Yutu-2 rover in 2019, this time touching down on the moon’s unexplored far side — an impressive first. A sample return mission on the moon’s near side in 2020 yields nearly 4 pounds (1.7 kilograms) of lunar rocks and dirt. Another sample return mission should be launching soon, but this time to the far side. Seen as NASA’s biggest moon rival, China aims to put its astronauts on the moon by 2030. 

Russia stumbles 

In 2023, Russia tries for its first moon landing in nearly a half-century, but the Luna 25 spacecraft smashes into the moon. The country’s previous lander — 1976’s Luna 24 — not only landed, but returned moon rocks to Earth. 

India triumphs on take 2  

After its first lander slams into the moon in 2019, India regroups and launches Chandrayaan-3 (Hindi for moon craft) in 2023. The craft successfully touches down, making India the fourth country to score a lunar landing. The win comes just four days after Russia’s crash-landing. 

Japan lands sideways 

Japan becomes the fifth country to land successfully on the moon, with its spacecraft touching down in January. The craft lands on the wrong side, compromising its ability to generate solar power, but manages to crank out pictures and science before falling silent when the long lunar night sets in. 

Private tries 

A privately funded lander from Israel, named Beresheet, Hebrew for “in the beginning,” crashes into the moon in 2019. A Japanese entrepreneur’s company, ispace, launches a lunar lander in 2023, but it, too, wrecks. Astrobotic Technology, a Pittsburgh company, launches its lander in January, but a fuel leak prevents a landing and dooms the craft. Astrobotic and Intuitive Machines plan more moon deliveries.

Montgomery, Alabama — The Alabama Supreme Court has ruled that frozen embryos can be considered children under state law, a ruling critics said could have sweeping implications for fertility treatments. 

The decision was issued in a pair of wrongful death cases brought by three couples who had frozen embryos destroyed in an accident at a fertility clinic. Justices, citing anti-abortion language in the Alabama Constitution, ruled that an 1872 state law allowing parents to sue over the death of a minor child “applies to all unborn children, regardless of their location.” 

“Unborn children are ‘children’ … without exception based on developmental stage, physical location, or any other ancillary characteristics,” Justice Jay Mitchell wrote in the majority ruling Friday from the all-Republican court. 

Mitchell said the court had previously ruled that fetuses killed while a woman is pregnant are covered under Alabama’s Wrongful Death of a Minor Act and nothing excludes “extrauterine children from the Act’s coverage.” 

The ruling brought a rush of warnings about the potential impact on fertility treatments and the freezing of embryos, which had previously been considered property by the courts. 

“This ruling is stating that a fertilized egg, which is a clump of cells, is now a person. It really puts into question the practice of IVF,” Barbara Collura, CEO of RESOLVE: The National Infertility Association, said in an interview Tuesday. The group called the decision a “terrifying development for the 1 in 6 people impacted by infertility” who need in-vitro fertilization. 

She said it raises questions for providers and patients, including if they can freeze future embryos created during fertility treatment or if patients could ever donate or destroy unused embryos. 

The plaintiffs in the Alabama case had undergone IVF treatments that led to the creation of several embryos, some of which were implanted and resulted in healthy births. The couples had paid to keep others frozen in a storage facility at the Mobile Infirmary Medical Center. A patient in 2020 wandered into the area and removed several embryos, dropping them on the floor and “killing them,” the ruling said. 

The justices ruled that wrongful death lawsuits by the couples could proceed. 

An anti-abortion group cheered the decision. “Each person, from the tiniest embryo to an elder nearing the end of his life, has incalculable value that deserves and is guaranteed legal protection,” Lila Rose, president and founder of Live Action said in a statement. 

Chief Justice Tom Parker issued a concurring opinion that quoted the Bible as he discussed the meaning of the phrase “the sanctity of unborn life” in the Alabama Constitution. 

“Even before birth, all human beings bear the image of God, and their lives cannot be destroyed without effacing his glory,” Parker said. 

Justice Greg Cook, who filed the only full dissent to the majority opinion, said the 1872 law did not define “minor child” and was being stretched from the original intent to cover frozen embryos. 

“Moreover, there are other significant reasons to be concerned about the main opinion’s holding. No court — anywhere in the country — has reached the conclusion the main opinion reaches,” he wrote, adding the ruling “almost certainly ends the creation of frozen embryos through in vitro fertilization (IVF) in Alabama.” 

The Alabama Supreme Court decision partly hinged on anti-abortion language added to the Alabama Constitution in 2018, stating that it is the “public policy of this state to ensure the protection of the rights of the unborn child.” 

Supporters at the time said it would “be a declaration of voters’ beliefs” and would have no impact unless states gain more control over abortion access. States gained control of abortion access in 2022. Critics at the time said it would have broad ramifications for civil and criminal law beyond abortion access and that it was essentially a “personhood” measure that would establish constitutional rights for fertilized eggs.

CAPE CANAVERAL, FLORIDA — Astronomers have discovered what may be the brightest object in the universe, a quasar with a black hole at its heart growing so fast that it swallows the equivalent of a sun a day. 

The record-breaking quasar shines 500 trillion times brighter than our sun. The black hole powering this distant quasar is more than 17 billion times more immense than our sun, an Australian-led team reported Monday in the journal Nature Astronomy. 

While the quasar resembles a mere dot in images, scientists envision a ferocious place. 

The rotating disk around the quasar’s black hole — the luminous swirling gas and other matter from gobbled-up stars — is like a cosmic hurricane. 

“This quasar is the most violent place that we know in the universe,” lead author Christian Wolf of Australian National University said in an email. 

The European Southern Observatory spotted the object, J0529-4351, during a 1980 sky survey, but it was thought to be a star. It was not identified as a quasar — the extremely active and luminous core of a galaxy — until last year. Observations by telescopes in Australia and Chile’s Atacama Desert clinched it. 

“The exciting thing about this quasar is that it was hiding in plain sight and was misclassified as a star previously,” Yale University’s Priyamvada Natarajan, who was not involved in the study, said in an email. 

These later observations and computer modeling have determined that the quasar is gobbling up the equivalent of 370 suns a year — roughly one a day. Further analysis shows the mass of the black hole to be 17 to 19 billion times that of our sun, according to the team. More observations are needed to understand its growth rate. 

The quasar is 12 billion light-years away and has been around since the early days of the universe. A light-year is 5.8 trillion miles.

LOISABA CONSERVANCY, Kenya — Conservationists in Kenya are celebrating as rhinos were returned to a grassy plateau that hasn’t seen them in decades.

The successful move of 21 eastern black rhinos to a new home will give them space to breed and could help increase the population of the critically endangered animals. It was Kenya’s biggest rhino relocation ever.

The rhinos were taken from three parks that are becoming overcrowded to the private Loisaba Conservancy, where herds were wiped out by poaching decades ago.

“It’s been decades since rhinos roamed here, almost 50 years ago,” said Loisaba security manager Daniel Ole Yiankere. “Their numbers were severely impacted by poaching. Now, our focus is on rejuvenating this landscape and allowing rhinos to breed, aiming to restore their population to its former splendor.”

Moving rhinos safely is a serious challenge. The 18-day exercise involved tracking the rhinos using a helicopter and then shooting them with tranquilizer darts. Then the animals — which weigh about a ton each — have to be loaded into the back of a truck for the move.

Disaster nearly struck early in the relocation effort, when a tranquilized rhino stumbled into a creek. Veterinarians and rangers held the rhino’s head above water with a rope to stop it from drowning while a tranquilizer reversal drug took effect, and the rhino was released.

Some of the rhinos were transferred from Nairobi National Park and made a 300-kilometer trip. Others came from two parks closer to Loisaba.

Rhinos are generally solitary animals and are at their happiest in large territories. As numbers in the three parks where the rhinos were moved from have increased, wildlife officials decided to relocate some in the hope that they will be happier and more likely to breed.

David Ndere, an expert on rhinos at the Kenya Wildlife Service, said their reproduction rates decrease when there are too many in a territory.

“By removing some animals, we expect that the rhino population in those areas will rise up,” Ndere said. “And then we reintroduce that founder population of at least 20 animals into new areas.”

Loisaba Conservancy said it has dedicated around 25,000 hectares to the new arrivals, which are a mix of males and females.

Kenya has had relative success in reviving its black rhino population, which dipped from around 20,000 in the 1970s to below 300 in the mid-1980s because of poaching, according to conservationists, raising fears that the animals might be wiped out completely in the country. Kenya now has around 1,000 black rhinos, the third biggest population behind South Africa and Namibia.

There are just over 6,400 wild black rhinos left in the world, all of them in Africa, according to the Save the Rhino organization.

Tom Silvester, the CEO of Loisaba Conservancy, said Kenya’s plan is to get its black rhino numbers to 2,000 over the next decade.

“Once we have 2,000 individuals, we will have established a population that will give us hope that we have brought them back from extinction,” he said.

Kenyan authorities say they have relocated more than 150 rhinos in the last decade.

An attempt to move 11 rhinos in 2018 ended in disaster when all of the animals died shortly after moving.

Ten of the rhinos died from stress, dehydration and starvation intensified by salt poisoning as they struggled to adjust to saltier water in their new home, investigations found. The other one was attacked by a lion.

Since then, new guidelines have been created for the capture and moving of rhinos in Kenya. Silvester said tests have been conducted on the water quality at Loisaba.

Kenya is also home to the last two remaining northern white rhinos on the planet. Researchers said last month they hope they might be able to save that subspecies after creating an embryo in a lab from an egg and sperm previously collected from white rhinos and transferring it into a surrogate female black rhino. The pregnancy was discovered in a postmortem after the surrogate died of an infection following a flood.

RIO DE JANEIRO — The small team of state public health workers slalomed between auto parts strewn across a Rio de Janeiro junkyard, looking for standing water where mosquitoes might have laid their eggs.

They were part of nationwide efforts to curtail a surge in Brazil of the mosquito-borne illness of dengue fever during the country’s key tourist season that runs through the end of February.

Paulo Cesar Gomes, a 56-year-old entomologist, found some mosquito larvae swimming in shallow rainwater inside a car bumper.

“We call this type of location a strategic point” because of the high turnover in items converging from all over, he said. “It’s difficult not to have mosquitoes here.”

Earlier in the month, just days before Rio kicked off its world-famous Carnival festivities, the city joined several states and the country’s capital in declaring a public health epidemic over this year’s greater-than-normal number of cases of dengue.

“We had more cases in January than any other January,” Ethel Maciel, head of health surveillance at Brazil’s Health Ministry, said in an interview with The Associated Press.

So far this year, Brazil has recorded 512,000 cases nationwide, including both confirmed and likely cases — nearly four times more than those registered in the same period a year ago.

There have been 425 deaths under investigation for dengue so far this year, with 75 confirmed, as compared with just over 1,000 for all of 2023.

Dengue is a viral infection transmitted to humans through the bite of infected mosquitoes. Frequent rains and high temperatures, which accelerate the hatching of mosquito eggs and the development of larvae, make the famously hot city of Rio especially susceptible to outbreaks.

Many who are infected never develop symptoms, but dengue can cause high fever, headache, body aches, nausea and a rash, according to the World Health Organization. While most get better after a week or so, some develop a severe form that requires hospitalization and can be fatal.

Health workers like Gomes, equipped with masks and plastic gloves, meticulously combed the junkyard on a hot morning, gently kicking and shaking piled up auto parts looking for any trace of the Aedes aegypti mosquito that can spread dengue.

Whenever he saw standing water Gomes grabbed a hand pipette out of his bag and looked for larvae, which he collected in a white plastic container. Captured mosquitos and larvae are kept alive and brought to a city laboratory to be tested for dengue.

At locations with positive tests, health agents spray the walls with a product that kills mosquitoes and then monitor the location for weeks.

Maciel, from the Health Ministry, said the first warning about a possible epidemic came in September.

Brazil’s leading research institute, the state-funded Oswaldo Cruz Foundation, or Fiocruz, came up with several scenarios indicating that Brazil could have as many as 4.2 million cases this year, up from 1.6 million in 2023.

Maciel said the surge is due to excessive heat and intense rain, both possible effects of climate change or El Niño, a natural, temporary and occasional warming of part of the Pacific that shifts weather patterns across the globe.

Maciel also cited the circulation of four dengue virus serotypes at the same time, one of which authorities had not seen in 15 years.

In Rio, more than 80% of mosquito breeding sites are located in residential properties, health officials say. So, efforts to combat dengue must start in homes, and raising awareness is key, said Mário Sérgio Ribeiro, a health surveillance official for Rio de Janeiro state.

State officials launched a “10 minutes that save lives” initiative to encourage residents to inspect their homes, offices and places of worship for any standing water.

Health workers and volunteers went door to door, pacing up and down the narrow streets of Rio’s Tabajara working-class neighborhood, or favela, to spread the word. They distributed leaflets and climbed on rooftops, looking for containers with rainwater.

One elderly woman, Vilza da Costa, told the AP she believes she contracted the disease.

“It started with a fever, then my body was itching all over, weakness, and a lot of pain. I was in a very bad way,” she said. “There are a lot of mosquitoes here.”

During Carnival, which ended Wednesday, health employees welcomed visitors with free repellent. A van with a giant crossed off mosquito and the words “Against Dengue Everyday” opened and closed the parades several nights, for millions of TV viewers to see.

Maciel said the effect of Carnival will not be known for another week. Even though dengue is not transmissible from person to person, increased tourism can boost the spread of the disease to locations that had not been affected.

It’s not clear if the cases have reached a peak and now “are going to start going down, or if the worst-case scenario is indeed happening,” Maciel said.
