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.
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.
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
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
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.
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.
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.

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.
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.
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.
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.
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.
A potentially Earth-like planet has been discovered orbiting a star located right next door to the sun. Should humanity try to send a probe there as soon as possible? The newly discovered planet, known as Proxima b, orbits the star Proxima Centauri, the closest star to the sun. Proxima Centauri is about 4.22 light-years — or 25 trillion miles (40 trillion kilometers) — from Earth. That's a daunting distance. But an initiative announced earlier this year aims to send superfast miniature probes to Proxima Centauri, on a journey that would take about 20 years. With the discovery of Proxima b, the founders of that initiative are even more eager to get going. [Proxima Centauri's Alien Planet Closer
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.
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.
It’s this attribute which means that perfume could also be used as ‘trace evidence’ along with these other materials. Scientists wrote in the journal Science and Justice that analysing fragrances could be particularly useful in cases where a crime has involved close physical contact, such as a sexual assault. “We’ve shown that first, perfume does transfer, and second, we can identify when that transfer has happened,” said director of the UCL Centre for the Forensic Sciences Dr Ruth Morgan.
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
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
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.
New 3D printing technology unveiled this week sharply increases the size of objects that can be produced, offering new possibilities to remake manufacturing in the auto, aerospace and other major industries. One application demonstrated by 3D printing machinery maker Stratasys would allow airlines to pick made-to-order airplane interiors that could be tweaked with the click of a mouse. "We're now talking about parts in feet and meters versus centimeters and inches," said Rich Garrity, Americas president for Stratasys.
Cows have such a peculiar role in modern society. Millions of them are cruelly abused every year at the hands of the animal agriculture industry, but they are also some of the most protected animals. Cattle ranchers look after cows to make sure they are not attacked, and when another animal is seen impeding on their grazing land or injuring them, ranchers will reach out to their local governments to get rid of the “pests.” We’ve seen wild horses driven out of their native land to protect livestock and now, the Washington Department of Fish and Wildlife is moving forward with plans to exterminate an entire pack of wolves in Washington due to recent attacks on livestock. Admittedly, this was not
Nearly a year after first making headlines around the world, "Tabby's star" is still guarding its secrets. In September 2015, a team led by Yale University astronomer Tabetha Boyajian announced that a star about 1,500 light-years from Earth called KIC 8462852 had dimmed oddly and dramatically several times over the past few years. Boyajian and her colleagues suggested that a cloud of fragmented comets or planetary building blocks might be responsible, but other researchers noted that the signal was also consistent with a possible "alien megastructure" — perhaps a giant swarm of energy-collecting solar panels known as a Dyson sphere. Astronomers around the world soon began studying Tabby's star with a variety of instruments, and reanalyzing old observations of the object, in an attempt to figure out what, exactly, is going on.
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
