An underwater expedition along the California coast has revealed for the first time a sunken World War II-era aircraft carrier once used in atomic tests in the Pacific. The expedition led by famed oceanographer Robert Ballard captured on Tuesday the wreckage of the USS Independence, located half a mile under the sea in the Greater Farallones National Marine Sanctuary. Scientists aboard the ocean research ship E/V Nautilus lowered two submersibles to the ocean floor to find a Hellcat fighter plane, anti-aircraft guns, hatches and the ship's name on the hull. The Independence was deliberately scuttled in 1951. Samples of marine life growing on the ship will be brought onboard to be tested for possible
All astronauts have degrees in science, engineering, or medicine, but other than that, there's no one path to NASA. My degrees are in physics and space physics, and I did well enough in university that I actually started working at the Johnson Space Center in Houston, Texas, as a robotics flight controller right after college. Getting hired by NASA is like getting through the world's strictest HR screen.
Dozens of people were killed in central Italy after a 6.2-magnitude earthquake nearly leveled hilltop towns and trapped residents under piles of rubble. The Wednesday morning earthquake is the latest in a string of deadly seismic events to strike Italy in the past four decades. The Mediterranean nation is particularly prone to earthquakes for a mix of geographical reasons, Jennifer Weston, a seismologist with the International Seismological Center in England, told Mashable.
The rates of divorce filings may peak twice a year, a new study from one state suggests. In a 14-year study of divorce filings in Washington state, researchers found that the rates of such filings consistently peaked in March and August. "People tend to face the holidays with rising expectations, despite what disappointments they might have had in years past," study co-author Julie Brines, an associate sociology professor at the University of Washington, said in a statement.
NASA scientists are putting the finishing touches on a spacecraft designed to rendezvous with Asteroid Bennu in 2018 to find clues about the origins of life.
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.
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.
Smaller schools least likely to offer subject Physics, as champions of the subject will remind you, is the cornerstone of many professions, including those in engineering, health care, aerospace, and architecture. And for students hoping to pursue those and other science, technology, engineering, and math fields during college, getting a jump on physics during high school is all but a requirement. Yet, across the country, 2 in 5 high schools don't offer physics, according to an Education Week Research Center analysis of data from the U.S. Department of Education's office for civil rights. The numbers are worse in some states than others: In both Alaska and Oklahoma, about 70 percent of high schools
A group of researchers at the Massachusetts Institute of Technology’s Computer Science and Artificial Intelligence Laboratory think they’ve found a solution that can significantly improve Wi-Fi performance. WiFi signals interfere with each other because there isn’t enough bandwidth on the wireless spectrum to handle all the traffic from the cellphones that are trying to use the spectrum at the same time.
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.
When it comes to sending rockets to Mars, the biggest hurdle NASA has faced is the amount of energy needed to carry a very small payload over such a long distance. Modern technology doesn't allow for us to get enough there to start a full Martian colony. But 24-year-old engineering student Gary Li believes he's found a solution with an efficient self-healing plasma rocket. Follow TI: On Facebook
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 percentage of U.S. mothers who breast-feed their newborns continues to rise, but many stop breast-feeding before their infant is 6 months old, according to a new report from the Centers for Disease Control and Prevention. In 2013, 81.1 percent of U.S. mothers said they started out breast-feeding their baby. Breast-feeding rates were highest in Utah, where 94.4 percent of mothers said they breast-fed their newborns in 2013.
Monsanto Co 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.
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
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.
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.
Russia has reached two more milestones in its endeavour to close the nuclear fuel cycle. Mashinostroitelny Zavod (MSZ) - part of Russian nuclear fuel manufacturer TVEL - has completed acceptance tests of components for its ETVS-14 and ETVS-15 experimental fuel assemblies with mixed nitride fuel for the BREST and BN fast neutron reactors. MSZ has also announced the start of research and development work on the technical design of the "absorbent element" of the core of the BREST-OD-300 reactor. Russia plans to construct 11 new nuclear power reactors (not including 5 under construction) by 2030 - including two BN-1200 sodium-cooled fast neutron reactors. The BN-1200 units are to be built at the
Researchers at Scotland's University of St. Andrews have demonstrated the world's first polariton laser based on lab-grown, fluorescent jellyfish proteins -- which could help trigger major advances in fields like optical computing. "I've always been fascinated by the material properties of fluorescent proteins," said Malte Gather, a professor at the University of St. Andrews, who helped invent the laser. "They have a very special molecular structure that is unlike the structure of any of the synthetic materials that we use." Polariton lasers are different in their physics from conventional lasers, and potentially more efficient at generating light at low energy levels. However, they have previously
If you hate parallel parking, or if you tend to avoid backing into spots at all costs, a new wireless camera that uses your smartphone as its display could help. The new backup camera for cars, dubbed RearVision, is powered by solar energy and uses Wi-Fi or Bluetooth to connect with your phone. The device also will be the first backup camera to update itself automatically to get better over time, according to Pearl Automation, the Silicon Valley-based company developing the gadget.
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.
One man's fatal lung infection highlights a rare danger that musicians may face: getting sick from fungi growing within their instruments, according to a recent report of the case. The 61-year-old man developed what his doctors in England described as "bagpipe lung," and died just a month after he was hospitalized for his infection, according to the case report, published today (Aug. 22) in the journal Thorax. The man had previously been diagnosed with a lung condition called hypersensitivity pneumonitis, in 2009, the doctors who treated him wrote.
Dr Vandana Shiva is an Indian scientist, environmental activist and world leading expert on food sustainability. At the age of 63, she has spent four decades studying where our food comes from, who is reaping the benefits of various farming methods, and what certain "developments" in agriculture are doing to the environment. In her new book, Who Really Feeds The World?, Shiva lays the problems with our current food system before us, and it's not looking good.
One person's lucky charm could be a local government's national treasure. Aileen Cynthia Maggay-Amurao, a tourism official from Puerto Princesa, Philippines, says the city is home to what could be the world's largest natural pearl on record.
A rare Tyrannosaurus rex skull has been discovered by a team of paleontologists and volunteers in northern Montana. It’s one of only 15 reasonably complete known skulls of the tyrant lizard king in the world. Two volunteers, Jason Love and Luke Tufts, were prospecting for dinosaurs when they saw a scattering of bone fragments falling out of a hillside. The bones were big and had the trademark honeycomb pattern of a large carnivore. After some digging into the sandstone it was clear that they were looking at the backside of a skull from a T. rex, the most iconic of the dinosaur predators. The team was led by paleontologist Greg Wilson with the University of Washington and Burke Museum as part
