Antarctic seas defy global warming thanks to chill from the deep
By Alister Doyle OSLO (Reuters) - A persistent chill in the ocean off Antarctica that defies the global warming blamed for melting Arctic ice at the other end of the planet is caused by cold waters welling up from the depths after hundreds of years, scientists said on Monday. The Southern Ocean off Antarctica may be among the last places on Earth to feel the impact of man-made climate change, with a lag of centuries to affect waters emerging from up to 5,000 meters (16,000 ft) deep, the U.S. study said. Many people who doubt mainstream scientific findings that human use of fossil fuels is warming the planet often point to the paradox of expanding winter sea ice off Antarctica in recent decades and a rapid shrinking of ice in the Arctic.
As much as 35 percent of northern and central Great Barrier Reef dead or dying: scientists
By Colin Packham SYDNEY (Reuters) - Mass bleaching has destroyed as much as 35 percent of the coral on the northern and central Great Barrier Reef, Australian scientists said on Monday, a major blow to the World Heritage Site that attracts about A$5 billion ($3.59 billion) in tourism each year. Australian scientists said in March just seven percent of the entire Great Barrier Reef had avoided any damage as a result of bleaching, and they held grave fears particularly for coral on the northern reef. After further aerial surveys and dives to access the damage across 84 reefs in the region, Australian scientists said the impact of the bleaching is more severe than they had expected.
New incentives needed to develop antibiotics to fight superbugs
By Bill Berkrot NEW YORK (Reuters) - Drugmakers are renewing efforts to develop medicines to fight emerging antibiotic-resistant bacteria, but creating new classes of drugs on the scale needed is unlikely to happen without new financial incentives to make the effort worth the investment, companies and industry experts said. "The return on investment based on the current commercial model is not really commensurate with the amount of effort you have to put into it," said David Payne, who heads GlaxoSmithKline PLC's antibiotics drug group. Other pharmaceutical companies expressed a similar sentiment.
Prototype space station module inflated on NASA's second try
By Irene Klotz CAPE CANAVERAL, Fla. (Reuters) - Astronauts aboard the International Space Station on Saturday inflated an experimental fabric module that may provide a less expensive and safer option for housing crews during long stays in space, a NASA TV broadcast showed. Designed and built by privately owned Bigelow Aerospace, the Bigelow Expandable Activity Module, or BEAM, is the first inflatable habitat to be tested with astronauts in space. Las Vegas-based Bigelow Aerospace previously flew two unmanned prototypes.
Neanderthals Likely Built These 176,000-Year-Old Underground Ring Structures
About 40,000 years before the appearance of modern man in Europe, Neanderthals in southwestern France were venturing deep into the earth, building some of the earliest complex structures and using fire. That's according to new research that more precisely dated bizarre cave structures built from stalagmites, or mineral formations that grow upward from the floor of a cave. Scientists discovered about 400 stalagmites and stalagmite sections that were collected and stacked into nearly circular formations about 1,100 feet (336 meters) from the entrance of Bruniquel Cave, which was discovered in 1990.
Scientists find minivan-sized sponge, world's largest
HONOLULU (AP) — Researchers in Hawaii have been absorbed by a sea creature they discovered last summer, and their findings are pretty big.
Scientists disagree over Zika risk at Brazil's Olympics
One day after a top U.S. health official declared there was no public health reason to cancel or delay this summer's Olympics in Brazil, more than 150 scientists on Friday called for just that, saying the risk of infection from the Zika virus is too high. The scientists, many of them bioethicists, who signed an open letter published online to Dr. Margaret Chan, director-general of the World Health Organization. The letter urged that the Games, due to be held in Rio de Janeiro in August, be moved to another location or delayed.
Snorkeling Paradise Inside a Volcano Named Best US Beach
Hanauma Bay's new title represents the third in a streak of winners from the island of Oahu in the annual "Best Beaches" rankings, which are put together annually by Stephen Leatherman, a coastal researcher at Florida International University also known as "Dr. Beach." Leatherman ranks the top 10 public beaches around the United States based on factors ranging from sand softness and wind speeds to wave height and pollution. "Frankly, the United States is blessed with hundreds of wonderful beaches," Leatherman told Live Science.
Rosetta spacecraft finds key building blocks for life in a comet
By Irene Klotz CAPE CANAVERAL, Fla. (Reuters) - Scientists for the first time have directly detected key organic compounds in a comet, bolstering the notion that these celestial objects delivered such chemical building blocks for life long ago to Earth and throughout the solar system. The European Space Agency's Rosetta spacecraft made several detections of the amino acid glycine, used by living organisms to make proteins, in the cloud of gas and dust surrounding Comet 67P/Churyumov-Gerasimenko, scientists said on Friday. Glycine previously was indirectly detected in samples returned to Earth in 2006 from another comet, Wild 2.
Can Stomach Botox Injections Help People Lose Weight?
Doctors are considering a new use for Botox: The drug may help obese people lose weight, according to early research. In addition, researchers in earlier studies assumed that Botox, which relaxes muscles, would help people lose weight because it would slow down the rate that the stomach empties itself.
