An astronaut has set a U.S. record for most time spent in space. Jeffrey Williams, commander of the International Space Station, marked his 521st day in orbit Wednesday, a number accumulated over four flights. That surpasses the 520-day record set by Scott Kelly, whose one-year space station mission ended in March. By the time Williams returns to Earth in two weeks, he will have logged 534 days off the planet for NASA. His record won't last long. Space station veteran Peggy Whitson will top that after she flies up in November for a six-month stay. She's already at the 377-day mark for total space time, a record for a woman. Kelly, who's now retired from NASA, called Williams from Mission Control
Capybaras, giant rodents that are native to South America, may be establishing themselves as an invasive species in Florida, according to Elizabeth Congdon, the only biologist in North America studying the animal. "Right now, they're considered exotics -- non-native animals that aren't supposed to be here," Congdon told ABC News today. Capybaras were first accidentally introduced to forests in northern Florida after five of them escaped a research facility in the early '90s, said Congdon, an assistant professor at the Bethune-Cookman University in Daytona Beach, Florida, who warned about the potential threat of the species at an animal behavior conference earlier this month.
It was a time of conquest and conversions. Over 250 years, from the 11th century onwards, the rulers of Bagan built more than 10,000 magnificent religious monuments. The stupas, temples and monasteries became the defining emblems of Bagan, the capital of the Pagan (pronounced PUH'-gahn) empire that ruled Myanmar from roughly 1044 to 1287.
Kids in the United States are sweet on sugar, but a major health organization is issuing new guidelines to curb children's consumption of sugary foods and beverages. In the first of three new recommendations from the American Heart Association (AHA), a panel of health and nutrition experts suggested that children ages 2 to 18 consume no more than 6 teaspoons (30 milliliters) of added sugar a day, according to the organization's statement published today (Aug. 22) in the journal Circulation. "There is little room in a child's diet for added sugars, because they need calories from vegetables, fruits, protein sources, whole grains and dairy to grow up healthy," said Dr. Miriam Vos, the chairperson of the committee that wrote the scientific statement, and an associate professor of pediatrics at Emory University School of Medicine in Atlanta.
Famed oceanographer Robert Ballard discovered the Titanic, the Bismarck, the USS Yorktown and John F. Kennedy's PT-109. On Tuesday, he added another accomplishment to his list of documenting the world's greatest shipwrecks: the first images in more than six decades of the USS Independence, an iconic World War II aircraft carrier scuttled in 1951 off the California coast, half a mile under the sea. In a 20-hour-long expedition, Ballard's team, working with officials from the Navy and NOAA -- the National Oceanic and Atmospheric Administration -- revealed breathtaking images of the lost carrier's flight deck, a Hellcat fighter plane, anti-aircraft guns, hatches, ladders and even the letters of the ship's name still visible on the hull, all submerged 30 miles west of Half Moon Bay.
The deadly earthquake that struck central Italy before dawn Wednesday occurred in a notorious seismic hotspot, and dangerous aftershocks are possible, scientists said. The US Geological Survey (USGS) reported that the quake occurred 10 kilometres (six miles) southeast of Norcia, measuring 6.2 on the moment magnitude scale and striking at a shallow depth of only 10 km (6.2 miles).
Seals in tiny hats might conjure up images of the circus or Sea World, but, in Antarctica, elephant seals with hat-like sensors are helping scientists study melting ice. The project to study the temperature and salinity of Antarctica bottom water (AABW) is led by Dr. Guy Williams of the University of Tasmania, and is supported by an international team of researchers who hope to find clues into the immediate effects of climate change.
Microbiologists at the University of Massachusetts Amherst have found a way to make electrical wires that are thousands of times thinner than a human hair. The secret? The "microbial nanowires," or little hair-like protein filaments, or pili, produced
With Tesla unveiling its Master Plan 2.0 that includes a fleet of shared, driverless vehicles, Ford's announcement that it will mass produce fully-autonomous cars by 2021, and Uber's plan to use driverless cars in Pittsburgh by the end of August, there has never been more enthusiasm for the potential of self-driving cars. But, while Tesla's Autopilot and other driver assistance systems have come a long way in advancing the technology behind autonomous driving, there are still some big technical hurdles to overcome to get these vehicles ready for the public—and that's fantastic news for tech jobs. If you're a software developer, engineer, roboticist, or designer, now has never been a better time
Four4Four Tech: Cincinnati Zoo reacts to Harambe meme onslaught; Tokyo Olympics eye smartphone gold, Tim Cooks fifth anniversary as Apple CEO, does Amazon have a cheap music service up its sleeve?
Paleontologists digging at the bottom of a strange cave in northern Wyoming say they have uncovered a trove of animal bones from the last ice age this summer and have enough funding to head back at the same underground site next year to continue their search. Scientists digging in July and led by Des Moines University anatomy professor Julie Meachen excavated wolf, bison, lion, cheetah and wolverine bones from Natural Trap Cave. The only way into or out of Natural Trap Cave on the arid western slope of the Bighorn Mountains is a 15-foot-wide hole in the ground. The paleontologists and their research assistants have to rappel down into the cave and bring lighting equipment to illuminate it.
Atlantic puffin chicks on Machias Seal Island in the Gulf of Maine have had the worst breeding season ever recorded, with the majority of chicks starving to death in burrows, scientists said. A drop in the puffins' food supply is to blame, said Tony Diamond, director of the Atlantic Laboratory for Avian Research at the University of New Brunswick. In a typical year, 60 percent of the puffin nests with eggs produce chicks that fly off the nest, and this year, the success rate was 12 percent, the Portland Press Herald (http://bit.ly/2bCwkaf) reported.
If your job causes stress and anxiety in your life, it may seem obvious that it may be bad for your health. A new study shows that people who had low levels of job satisfaction in their 20s and 30s may have an increased risk of mental health problems in their 40s. "We found that there is a cumulative effect of job satisfaction on health that appears as early as your 40s," lead author Jonathan Dirlam, a doctoral student in sociology at The Ohio State University, said in a statement.
Six scientists are close to wrapping up a year of near isolation in a Mars simulation on a Hawaii mountain. The scientists are housed in a dome on Mauna Loa and can go outside only in spacesuits, the Hawaii Tribune-Herald reported. Kim Binsted, principal investigator for the Hawaii Space Exploration Analog and Simulation, said this simulation is the second-longest of its kind after a mission that lasted 520 days in Russia.
Most quakes occur at shallow depths, according to the U.S. Geological Survey. Italy's quake was very shallow, originating between 2 1/2 miles (4 kilometers) and 6 miles (10 kilometers) underground, according to Italy's geological service and the USGS. By contrast, the 6.8 quake in Myanmar was deeper — at 52 miles (84 kilometers), which is considered an intermediate depth.
Embraced by kings and freedom fighters alike, Myanmar's peacocks have long been a national symbol of pride and resistance -- but they are becoming ever harder to spot in the wild. Ornithologist Thet Zaw Naing is worried. Every year that goes by, Myanmar's national bird becomes a less familiar sight.
The world's oldest found Tyrannosaurus rex is about to take flight. Trix, a 66-million-year-old female fossil found in Montana, will board a KLM Royal Dutch Airlines flight from Chicago to Amsterdam on Tuesday. Trix even has her own passport, whose headshot accurately captures the mood of most people in long airport security lines.
There are many national security challenges facing the United States, but too often our focus is exclusively on threats from terrorism, geopolitics and cyberattacks. As the country confronts the arrival of the Zika virus and contemplates travel bans to Miami, it’s time to have an adult conversation about the threats posed by biology.
Humans are likely to blame, with developers building on traditional habitats and farmers changing landscapes, but British citizens are stepping up to do what they can for the spiny little beasts. Some hold official, paying positions (a job in Ipswich garnered approximately 150 applications this summer), while others, like Linda Cleme, volunteer their time, working to rehabilitate hedgehogs. "I've got very fond of hedgehogs because they don't cause any harm to people," she told the Wall Street Journal.
Monsanto Co (MON.N) has withdrawn an application seeking approval for its next generation of genetically modified cotton seeds in India, a major escalation in a long-running dispute between New Delhi and the world's biggest seed maker. A letter sent by Monsanto's local partner in India, the conglomerate's biggest market outside the Americas, strongly objects to a government proposal that would force Monsanto to share its technology with local seed companies.
Men who earn more money than their wives may be rolling in the bucks, but they tend to have poor health and heightened anxiety, new research shows. Researchers analyzed surveys from 9,000 young married men and women in the United States taken annually over a 15-year period, and evaluated each participant's response on income, health and psychological wellness. The findings suggest that men who are primary breadwinners — and who, in essence, fulfill the culturally held expectation that husbands should bring home more money than their wives — are actually worse off than men who earn salaries that are more equal to those of their wives.
It was as if millions of voices suddenly cried out in terror, and were suddenly silenced. The fate of Pluto, reality's Alderaan, well metaphorically at least, was sealed when it lost its status as "Ninth Planet of Our Solar System." Sniff. One of my favorite T-shirts is the one acts as epitaph for Pluto with the words, "Revolve in Peace, 1930-2006." For more than 76 years, Pluto was dubbed planet, but on Aug. 24, 2006, it was demoted to dwarf planet. So today is the 10-year anniversary of its passing. Today is #PlutoDemotedDay Mourn appropriately. Of course now we know that the little planet that could (whether you think of it as dwarf or not) is much more interesting than we ever knew, thanks
China has been aggressively expanding its space program in recent years. It launched the Chang'e 3 mission back in 2013 that carried its Yutu rover, which lasted for two years when it was supposed to last only for three months, to the moon. The country also launched a quantum satellite in mid-August to enable hack-proof communications. The six-wheeled rover it's blasting off to space in 2020 will be larger than Yutu at 441 pounds. It will be equipped with 13 different instruments, including a radar that can drill into the ground and a remote-sensing camera, to take a closer look at the Martian soil and environment. Like Yutu, it's only supposed to gather and beam back data for three months, though
A Filipino fisherman in western Palawan island has found possibly the world's biggest pearl, which he had hidden under a bed for more than 10 years as a lucky charm, a tourism official said Thursday. Aileen Amurao, Puerto Princesa city's tourism officer and the fisherman's relative, said Thursday the man gave her the 34-kilogram (75-pound) pearl that's 2.2 feet (67 centimeters) long and 1 foot (30 centimeters) wide last month for safekeeping because he was moving to a new place. The fisherman, his father and brothers found the irregular-shaped pearl inside a giant clam that stuck to their boat's anchor when they sought refuge from a squall on a reef, Amurao said.
A new group of critically endangered primates has been spotted in Vietnam, raising hopes the rare creatures may not be wiped out in the next decade as scientists had feared. The Delacour's langur, black and white with a full face of whiskers, is indigenous to Vietnam, but their numbers have dwindled in recent years because of poaching and mining activity in the country's northern forests. "It's great news for this particular species because had we not found this new population, they were in grave danger of being wiped out within a decade," spokeswoman for FFI in Vietnam, Akofa Wallace, told AFP Tuesday.
