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
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.
A baby in Brazil who became infected with Zika in the womb still had the virus in his body for months after he was born, according to a new report of the case. The baby's mother, who lived in São Paulo, showed symptoms of Zika when she was 26 weeks pregnant, according to the report, published today (Aug. 24) in the New England Journal of Medicine. When the baby was born, he was diagnosed with microcephaly, or an abnormally small head and brain.
The humanitarian group's USA executive director Jason Cone says they decided not to negotiate for the American hostage's freedom. Kayla was about Doctors Without Borders vehicle when she was captured by crisis in Syria.
The European Space Agency's Rosetta probe has captured images of a bright burst of light on the comet it is orbiting, apparently caused by a landslide. The dramatic light flashes were recorded Feb. 19 and accompanied by rising temperatures and sharp increases in dust, gas and plasma released from comet 67P/Churyumov-Gerasimenko. Eberhard Gruen of the Max-Planck-Institute for Nuclear Physics in Heidelberg, Germany, said Thursday that a landslide on the comet's surface was most likely responsible. The flashes would have been generated by light reflecting from dust particles kicked up by the landslide. The European Space Agency plans to crash-land Rosetta on the comet's surface Sept. 30, more than
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.
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.
American astronaut Jeff Williams has set a new record for most cumulative time in space for a U.S. astronaut. On Wednesday, Williams surpassed 520 days living in space, breaking Scott Kelly’s record set during his nearly year-long mission aboard the International Space Station. Williams will be heading back to Earth on September 6, which will extend his record to 534 days. The first 10 days of Williams’ time in space date back to 2000, when he was a flight engineer aboard Space Shuttle Atlantis during STS-101 as the shuttle was involved in helping put the finishing touches on the space station. According to NASA, Williams returned to space in 2006 for a six-month flight aboard the ISS. He returned
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.
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.
Powerful earthquakes like the 6.2-magnitude temblor that rocked central Italy early this morning (Aug. 24) are surprisingly common in the region, geologists say. The shaking was caused by movement in the Tyrrhenian Basin, a seismically active area beneath the Mediterranean Sea. Here, the ground is actually spreading apart, said Julie Dutton, a geophysicist with the U.S. Geological Survey.
A team of physicians and neuroscientists on Wednesday reported the successful use of ultrasound waves to “jump start” the brain of a 25-year-old man recovering from coma — and plan to launch a much broader test of the technique, in hopes of finding a way to help at least some of the tens of thousands of patients in vegetative states.
A government panel has cleared commercial use of what would be India's first genetically modified (GM) food crop, but politicians still have to give final approvals amid wide-spread public opposition. Technical clearance for indigenously developed GM mustard seeds was given on Aug. 11 by the panel of government and independent experts, following multiple reviews of crop trial data generated over almost a decade, said two sources with direct knowledge of the matter. The decision to go ahead is likely to be made public soon by the environment ministry's Genetic Engineering Approval Committee, and is expected eventually to move to Prime Minister Narendra Modi's desk via Environment Minister Anil Madhav Dave.
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.
A Filipino fisherman in western Palawan island has found possibly the world's biggest pearl, but he didn't know it. The fisherman's family would rub it with their hands before going out to sea in the belief it would bring them luck, said relative Aileen Amurao. Amurao, who is also Puerto Princesa city's tourism officer, said Thursday that the man gave her the pearl last month for safekeeping because he was moving to a new place.
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.
Much of the universe is made of dark matter, the unknowable, as-yet-undetected stuff that barely interacts with the "normal" matter around it. In the Milky Way, dark matter outnumbers regular matter by about 5 to 1, and very tiny dwarf galaxies are known to contain even more of the stuff. But now scientists have found something entirely new: a galaxy with the same mass as the Milky Way but with only 1 percent of our galaxy's star power. About 99.99 percent of this other galaxy is made up of dark matter, and scientists believe it may be one of many. The galaxy Dragonfly 44, described in a study published Thursday in the Astrophysical Journal Letters, is 300 million light years away. If scientists
American biohacker Amal Graafstra, 40, decided in 2005 that he wanted to be done with such archaic technology "from like 700 BC." He looked at iris scanning and fingerprint reading as solutions for opening his office door, but decided those options were expensive and unreliable. Attitudes are changing as people become more familiar with the idea of implants.
The dodo bird is extinct — but one collector can now have their own dodo skeleton. Summers Place Auctions is selling what it describes as a rare composite skeleton of a dodo bird, a creature once found on the island of Mauritius. Although individual bones of the flightless bird come up for sale occasionally, Summers Place director Rupert van der Werff says this is the first time a nearly complete skeleton has come up for sale since the early 20th century.
Cancer has passed heart disease as the leading cause of death in nearly half of U.S. states, according to a new report. In 2014, cancer was the leading cause of death in 22 states, including many in the West and Northeast. In the rest of the 28 states, heart disease remained the leading cause of death in 2014.
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
By Alister Doyle OSLO (Reuters) - The Earth has gained coastal land equivalent to the size of Jamaica in the past 30 years with man-made construction outpacing erosion caused by rising sea levels, mapping data showed on Thursday. Using satellite data with Google Earth, Deltares said coastal regions had gained a net 13,565 square kilometers (5,237 square miles) of land since 1985, roughly the size of Jamaica or the U.S. state of Connecticut. "We expected on average the coast to shrink ... as sea level has risen," said Fedor Baart of Deltares, an author of the study published in the journal Nature Climate Change.
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.

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.
