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.
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).
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.
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.
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.
In the heart of North Dakota's prairie lands, tribal leaders and their allies are squaring off against a Texas pipeline builder and the federal government. Over a thousands protesters have gathered during the past two weeks in a grassy camp near the town of Cannon Ball to physically block construction of the Dakota Access Pipeline in the area. On Wednesday, the U.S. District Court for the District of Columbia will hear the tribe's lawsuit, which claims a federal agency violated multiple statutes for protecting clean water and culturally significant sites by issuing permits to Energy Transfer Partners, the pipeline's builder.

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.
Researchers from the University of Austin have developed a new process for making "smart tinting" plastic that could help save on heating and cooling bills. Paired with a sunlight sensor, you could easily get Transitions for your whole house.
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.
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.
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.
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.
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
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
Man-made global warming may have started a few decades earlier than scientists previously figured, a new study suggests. Instead of the late 1800s, a slight almost imperceptible warming can now be tracked to around the 1850 in North America, Europe and Asia, according to a new study based on coral, microscopic organisms, ice cores, cave samples, tree rings and computer simulations.
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.
Such an incident could potentially mean years of work lost, and that not only relates to the blood, sweat and tears expended keeping the spacecraft in operation far from Earth, but also the massive amount of preparation needed to get the thing off the ground in the first place. In October 2014, the situation looked serious for NASA engineers working on the Solar and Terrestrial Relations Observatory (STEREO) mission when they lost touch with one of two sun-studying spacecraft eight years after launch. The breakdown occurred while NASA was testing a set of important procedures designed to keep the satellites operating throughout an upcoming four-month communications blackout caused by interference from the sun.
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.
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.
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
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.
An ancient Mayan text captured the moment when a royal astronomer made a scientific discovery about the movement of Venus across the night sky. The text, called the Dresden Codex, contains laborious measurements of the rising and setting of Venus. Based on these recordings, historians can now place this astronomer within a 25-year span within the first half of the 10th century. "We can see the moment when this person puts it all together," said Gerardo Aldana, a science historian in the Department of Chicano Studies at the University of California, Santa Barbara and a co-author of a new study describing the findings.

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
