NASA on Wednesday showed off its first asteroid samples delivered last month by a spacecraft — the most ever returned to Earth. Scientists and space agency leaders took part in the reveal at Johnson Space Center in Houston. The ancient black dust and chunks are from the carbon-rich asteroid named Bennu, almost 60 million miles away. NASA's Osiris-Rex spacecraft collected the samples three years ago and then dropped them off sealed in a capsule during a flyby of Earth last month. Scientists anticipated at least a cupful of rocks, far more than what Japan brought back from a pair of missions years ago. They're still not sure about the exact quantity. That's because the main sample chamber has yet to be opened, officials said. "It's been going slow and meticulous,"…

Tens of millions in the Americas will have front-row seats for Saturday's rare "ring of fire" eclipse of the sun.  What's called an annular solar eclipse — better known as a ring of fire — will briefly dim the skies over parts of the western U.S. and Central and South America.  As the moon lines up precisely between Earth and the sun, it will blot out all but the sun's outer rim. A bright, blazing border will appear around the moon for as much as five minutes, wowing sky gazers along a narrow path stretching from Oregon to Brazil.  The celestial showstopper will yield a partial eclipse across the rest of the Western Hemisphere.  It's a prelude to the total solar eclipse that will sweep across Mexico, the eastern half…

Monday is World Mental Health Day. This year’s theme is “Mental health is a basic universal human right.” People all over the world who have mental health conditions, according to the World Health Organization, face discrimination. “Having a mental health condition should never be a reason to deprive a person of their human rights or to exclude them from decisions about their own health,” WHO said in a statement. “Yet all over the world, people with mental health conditions continue to experience a wide range of human rights violations.” The WHO says, “one in eight people globally are living with mental health conditions, which can impact their physical health, their well-being, how they connect with others, and their livelihoods.” World Mental Health Day was initiated in 1992 by the World…

In fifth grade, Stella Gage's class watched a video about puberty. In ninth grade, a few sessions of her health class were dedicated to the risks of sexual behaviors. That was the extent of her sex education in school. At no point was there any content that felt especially relevant to her identity as a queer teenager. To fill the gaps, she turned mostly to social media. "My parents were mostly absent, my peers were not mature enough, and I didn't have anyone else to turn to," said Gage, who is now a sophomore at Wichita State University in Kansas. Many LGBTQ+ students say they have not felt represented in sex education classes. To learn about their identities and how to build healthy, safe relationships, they often have had to…

A dose of patience may come in handy at the pharmacy counter this fall. Drug and staffing shortages haven't gone away. Stores are starting their busiest time of year as customers look for help with colds and the flu. And this fall, pharmacists are dealing with a new vaccine and the start of insurance coverage for COVID-19 shots. Some drugstores have addressed their challenges by adding employees at busy hours. But experts say many pharmacies, particularly the big chains, still don't have enough workers behind the counter. Chris Adkins said he left his job as a pharmacist with a major drugstore chain a couple years ago because of the stress. Aside from filling and checking prescriptions, Adkins routinely answered the phone, ran the register and stocked pharmacy shelves. "I just…

A massive number of migrating birds collided with McCormick Place — a Chicago convention center — this week, resulting in an unprecedented number of bird deaths. Dave Willard has collected dead and injured birds from around the center during the migration season for about 40 years. In an interview with the Audubon website, Willard said that he and his colleagues collected 964 dead birds and approximately 80 “stunned live ones.” “It was truly unprecedented,” he said of Thursday’s event. Hundreds more dead and injured birds were subsequently found around the city. Before this week’s catastrophe, the largest number of dead birds he had collected was 200. “Unfortunate weather” combined with “disorienting brightly lit buildings” confused the birds, resulting in the high death and injury numbers. “You pick up a Rose-breasted…

Spanish company PLD Space launched its reusable Miura-1 rocket early on Saturday from a site in southwestern Spain, carrying out Europe's first fully private rocket launch and offering hope for the continent's stalled space ambitions. The startup's test nighttime launch from Huelva came after two previous attempts were scrubbed. The Miura-1 rocket, named after a breed of fighting bulls, is as tall as a three-story building and has a 100-kilogram cargo capacity. The launch carries a payload for test purposes, but this will not be released, the company said. Mission control video showed engineers cheering as the rocket gained altitude against the dark nighttime sky, shouting for joy and congratulating one another. A first attempt to launch the Miura-1 rocket in May was abandoned due to strong high-altitude winds. A…

Indian rescuers are searching for over 100 people missing in a flash flood caused by a glacial lake bursting its banks, a risk scientists warn is increasing with climate change. Agence France-Presse explains what glacial lake outburst floods are and the risks they pose, particularly in parts of Asia. What is a glacial lake outburst flood? A glacial lake outburst flood, or GLOF, is the sudden release of water that has collected in former glacier beds. These lakes are formed by the retreat of glaciers, a naturally occurring phenomenon that has been turbocharged by the warmer temperatures of human-caused climate change. Glacier melt is often channeled into rivers, but ice or the build-up of debris can form what is effectively a natural dam, behind which a glacial lake builds. If…

At a rally Friday in the southern city of Blantyre, unemployed nurses called for more jobs and gave Malawi's president 14 days to help them find new opportunities for work. Frank Kamwendo, the chairperson of concerned nurses, said the demonstrations were a last resort after several meetings with Malawi government officials. "We have been trying our level best to discuss with the Ministry of Health, Ministry of Labor and the Ministry of local government to recruit more than 2,260 nursing officers," said Kamwendo. "Unfortunately, these ministries have been telling us that there are no funds for recruitment." Kamwendo said the nurses have also tried in vain to get the government to help them work in other countries. Thousands without jobs Government statistics show that Malawi has about 3,000 unemployed nurses…

A study published Friday indicates 1 in 10 babies around the world are born prematurely — before 37 weeks — leading to deaths, disability and chronic illnesses. The study was conducted by the World Health Organization, the U.N. Children’s Fund, UNICEF and the London School of Hygiene and Tropical Medicine. The study monitored global births between 2010 and 2020 and documented global, regional and country estimates and trends. It found 13.4 million babies — 1 in 10 of all live births — were born prematurely in 2020, with large disparities between regions and nations. It showed about 65% of 2020 preterm births worldwide occurred in sub-Saharan Africa and southern Asia, where more than 13% of all births were preterm. The rates in the most affected countries — Bangladesh, 16.2%; Malawi…

AT&T and Gallaudet University have developed a football helmet for players who are deaf or hard of hearing and communicate using American Sign Language.  The company and the Washington-based school for students who are deaf or hard of hearing unveiled the new technology Thursday.  It allows a coach to call a play on a tablet from the sideline that then shows up visually on a small display screen inside the quarterback's helmet. Gallaudet, which competes in Division III, was cleared by the NCAA to use the helmet in its game on Saturday at home against Hilbert.  Gallaudet coach Chuck Goldstein said he thinks the helmet "will change football."  "We work out the same way as every other college football program, we practice the same way, we compete the same way,"…

All About America explores American culture, politics, trends, history, ideals and places of interest. Money may not buy happiness, but a new analysis of the happiest and unhappiest U.S. states suggests the lack of cash can contribute to a person’s misery. “The thing about money and happiness is that being increasingly and increasingly wealthy doesn't make you more and more happy, but experiencing poverty definitely can make you unhappy,” says Miriam Liss, professor of psychology at the University of Mary Washington in Fredericksburg, Virginia. That’s because basic needs of shelter, food, clothing, safety, health care and transportation are hard to meet when people aren’t financially secure, she adds. In order to assess levels of happiness in all 50 states, personal finance company WalletHub looked at three key factors: emotional and…

Japan's wrecked Fukushima nuclear power plant said it began releasing a second batch of treated radioactive wastewater into the sea on Thursday after the first round of discharges ended smoothly. Plant operator Tokyo Electric Power Company Holdings said workers activated a pump to dilute the treated water with large amounts of seawater, slowly sending the mixture into the ocean through an underground tunnel. The wastewater discharges, which are expected to continue for decades, have been strongly opposed by fishing groups and neighboring countries including South Korea, where hundreds of people staged protest rallies. China banned all imports of Japanese seafood, badly hurting Japanese seafood producers and exporters. The plant's first wastewater release began Aug. 24 and ended Sept. 11. During that release, TEPCO said it discharged 7,800 tons of treated…

More than 75,000 Kaiser Permanente health care staff across the U.S. began a three-day strike Wednesday, which will likely hold up appointments, test results and prescriptions at locations across the nation. Kaiser Permanente, a California-based chain of hospitals, pharmacies and clinics, serves nearly 13 million Americans. The Coalition of Kaiser Permanente Unions, which represents about 85,000 company workers, announced a three-day strike in California, Colorado, Oregon and Washington state, and a daylong strike in Virginia and Washington, D.C., after contract negotiations stalled overnight. More than 75,000 Kaiser Permanente employees are expected to join in. Talks restarted Wednesday. A key complaint from those on the picket line is that understaffing is inundating workers and delaying vital care. "We’re striking for our patients," said Mikki Fletchall, a licensed vocational nurse at a…

France has urged the public not to worry about reports of bedbug outbreaks on public transportation in Paris and throughout the country. At least 37 sightings of bedbugs on public transportation have been reported over the past few weeks by national rail operator SNCF, with a dozen additional reports made to Paris public transport operator RATP. French Transport Minister Clément Beaune said that each report had been checked out, and that none were proved to be true. “When there is a problem, we deal with it. We won’t deny it,” Beaune said. “There is no outbreak of bedbugs in public transportation.” French media have reported extensively about bedbugs on trains and in cinemas, and the government worries about the impact on tourism and the Paris Olympics, which start in less…

Scientists Moungi Bawendi, Louis Brus and Alexei Ekimov won the 2023 Nobel Prize in Chemistry for "the discovery and synthesis of quantum dots," which illuminate computer monitors and television screens and are used by doctors to map tumors. "The Nobel Laureates ... have succeeded in producing particles so small that their properties are determined by quantum phenomena. The particles, which are called quantum dots, are now of great importance in nanotechnology," the Nobel Committee for Chemistry said in a statement. "Researchers believe that in the future they could contribute to flexible electronics, tiny sensors, thinner solar cells and encrypted quantum communication." Nanoparticles and quantum dots are used in LED-lights and can also be used to guide surgeons while removing cancer tissue. The more than century-old prize is awarded by the…

Wearing an "I Love Pandas" T-shirt and clutching a panda-covered diary, 10-year-old Kelsey Lambert bubbled with excitement as she glimpsed the real thing. She and her mother, Alison, had made a special trip from San Antonio, Texas, just to watch the National Zoo's furry rock stars  munch bamboo and roll on the grass.  "It felt completely amazing," Kelsey said on Friday. "My mom has always promised she would take me one day. So, we had to do it now that they're going away."  The National Zoo's three giant pandas — Mei Xiang, Tian Tian and their cub Xiao Qi Ji — are set to return to China in early December with no public signs that the 50-year-old exchange agreement struck by President Richard Nixon will continue.  National Zoo officials have…

A new malaria vaccine approved Monday for use by the World Health Organization could be rolled out in African countries in the next few months, potentially saving hundreds of thousands of children’s lives in the coming years. The new vaccine, known as R21, was developed by Britain’s Oxford University along with the Serum Institute of India. It is already in use in Ghana and Burkina Faso. “This new approval for R21 has the potential now that vaccination can occur across sub-Saharan Africa and protect many more children at risk,” said Professor Azra Ghani, an infectious disease epidemiologist at Imperial College London. “We estimate that if this is rolled out across the continent at the sort of coverage levels that we've seen in the implementation study so far, this could avert…

The Nobel Prize in physics was awarded Tuesday to three scientists who look at electrons in atoms during the tiniest of split seconds. Pierre Agostini of The Ohio State University in the U.S.; Ferenc Krausz of the Max Planck Institute of Quantum Optics and Ludwig Maximilian University of Munich in Germany; and Anne L'Huillier of Lund University in Sweden won the award. Their experiments "have given humanity new tools for exploring the world of electrons inside atoms and molecules," according to the Royal Swedish Academy of Sciences, which announced the prize in Stockholm. They "have demonstrated a way to create extremely short pulses of light that can be used to measure the rapid processes in which electrons move or change energy." At the moment, this science is about understanding our…

The World Health Organization on Monday announced the recommendation of a second malaria vaccine, with the aim of giving countries a cheaper and more readily available option to tackle the deadly disease. Developed by Oxford University with the help of the Serum Institute of India, the new vaccine, known as R-21, will be rolled out in some African countries early next year, and expand into other countries later in 2024, according to WHO chief Tedros Adhanom Ghebreyesus. Research that has not yet undergone the usual process of scientific review suggests the three-dose vaccine to be around 75% effective. Boosters would be available for continued protection. "Almost exactly two years ago, WHO recommended the broad use of the world's first malaria vaccine called RTS,S" also known as Mosquirix, Tedros told a…

Two scientists who jointly worked on the ground-breaking technology behind some of the most effective COVID-19 vaccines have been awarded the 2023 Nobel Prize for medicine, one of the most prestigious accolades in the field. Hungarian American scientist Katalin Kariko and her American colleague, Drew Weissman, began working on so-called “mRNA” technology in the early 1990s at the University of Pennsylvania. Their breakthrough was crucial in developing the Moderna and Pfizer-BioNtech coronavirus vaccines, which have proved among the most effective in tackling COVID-19. Lifesaving vaccines The Nobel Prize in Medicine Committee in Sweden said the discovery had helped defeat one of the greatest threats to human health in modern times. “mRNA vaccines, together with other COVID-19 vaccines, have been administered over 13 billion times. Together, they have saved millions of…

An endangered Sumatran rhinoceros, the smallest and hairiest of the five extant rhino species, was born in Indonesia last week in a conservation area, the government said Monday.  Weighing about 27 kilograms (59.52 lbs.), the yet-to-be named female calf, was born Saturday at the Sumatran Rhino Sanctuary (SRS) facility in Way Kambas National Park, Lampung province in the tropical Southeast Asian country.  Covered in black hair, the newborn stood about 45 minutes after her birth. On the next day, she began to walk around the jungle, the environment ministry said in a statement.  The mother, 22-year-old Ratu, was in a healthy condition, the ministry said.  Ratu is a native of Lampung, while her mate, Andalas, aged 23, was born at the Cincinnati Zoo, in the midwestern U.S. state of Ohio,…
