Parts of Great Barrier Reef face permanent destruction due to El Nino: scientists

By Colin Packham SYDNEY (Reuters) - Parts of Australia's Great Barrier Reef face permanent destruction if the current El Nino, one of the strongest in two decades, does not ease this month, scientists said on Wednesday. The El Nino is a result of a warming of the ocean in the western Pacific -- ideal conditions for coral bleaching, where coral expels living algae, causing it to calcify. The scientists said areas of the Great Barrier Reef, a world heritage site, are experiencing the worst bleaching in 15 years.

Station crew heads home after record U.S. spaceflight

By Irene Klotz CAPE CANAVERAL, Fla. (Reuters) - NASA astronaut Scott Kelly and Russian cosmonaut Mikhail Kornienko headed back toward Earth on Tuesday after nearly a year aboard the International Space Station, ending a record-long U.S. spaceflight intended to pave the way for human travel to Mars. The men, accompanied by Russian cosmonaut Sergey Volkov, strapped themselves inside a Russian Soyuz capsule and departed the station at 8:02 p.m. EST (0102 GMT on Wednesday). Kelly and Kornienko have been aboard the space station for 340 days, about twice as long as previous crews.

Fifty shades of gray (or more): gene for graying hair identified

By Will Dunham WASHINGTON (Reuters) - They may not have settled the enduring debate over whether gray hair makes a person look distinguished or just plain old, but scientists have identified for the first time a gene behind graying hair. Researchers said on Tuesday an analysis of DNA from more than 6,300 people from five Latin American countries enabled them to pinpoint a gene that affects a person's likelihood of getting gray hair. The gene, called IRF4, is involved in regulating melanin, the pigment responsible for hair color as well as the color of the skin and eyes.

Essure Birth Control Controversy: 5 Things You Should Know

A permanent birth-control implant called Essure will need to be labeled with a stronger warning that lists potentially serious risks of the device, the Food and Drug Administration announced this week. The action comes after the FDA received more than 5,000 reports of complications from the device, including chronic pain, bleeding and allergic reactions, since the device was approved in 2002. What is Essure and who gets the device?

Leonardo DiCaprio Is Kind of Right About Less Snow

Snow might not be as hard to come by as Leonardo DiCaprio suggested it was during his Oscar acceptance speech Sunday night (Feb. 28), but climate trends do suggest that the actor is onto something, experts said. "Making 'The Revenant' was about man's relationship to the natural world," DiCaprio said at the Dolby Theatre in Los Angeles. The answer is yes, but only during the spring, said David Robinson, a professor in the Department of Geography at Rutgers University in New Jersey.

Aerojet on track to complete work on AR1 rocket engine by 2019 - CEO

Aerojet Rocketdyne Holdings Inc is on track to complete development of its AR1 rocket engine by 2019 as a replacement for the Russian-built RD-180 engine after receiving a funding "booster shot" from the U.S. Air Force on Monday, Chief Executive Officer Eileen Drake told Reuters on Tuesday. Drake said the Air Force's $115-million contract for work on the AR1 prototype, along with options that could increase the government's investment to $501 million in coming years, moved the U.S. military a step closer to ending its reliance on Russian engines for national space launches.

Zika Virus Linked to Guillain-Barré in New Study

A new study from French Polynesia provides the strongest evidence to date of a link between the Zika virus and the rare neurological condition Guillain-Barré syndrome (GBS), researchers said. In GBS, a person's own immune system damages the nerve cells, causing muscle weakness, and sometimes, paralysis in adults and children. In the new study, researchers analyzed blood samples from 42 adults who were diagnosed with Guillain-Barré between November 2013 and February 2014 during the Zika virus outbreak in French Polynesia.

Moving Ink: Cool Animation Tech Brings Tattoos to Life

In July 2015, Oskar & Gaspar, a collective of multimedia and visual artists based in Portugal, staged a landmark event in Lisbon, Portugal, called "Ink Mapping" that used projection mapping to transform tattoos into dynamic works of art. Projection mapping combines traditional projection technology with software that conforms the projected media to fit within the boundaries of a three-dimensional surface — like a building façade — rather than a flat, rectangular screen. This allows artists to design motion sequences that follow a unique pathway of planes, curves and crevices, embracing the architecture and structure of the projection surface as part of the visual story.

New Scans of King Tut's Tomb May Reveal Hidden Burial Chamber

On April 2, a new series of radar scans will be performed on King Tutankhamun's tomb to search for hidden chambers that may contain an undiscovered royal burial, Egypt's antiquities ministry has announced. The announcement comes after stories were published in numerous media outlets last week claiming that Egypt's tourism minister, Hisham Zazou, had told the Spanish news outlet ABC that the chambers had been proven to exist and contain numerous treasures. Last year, University of Arizona Egyptologist Nicholas Reeves published findings suggesting that there are hidden chambers behind a wall in Tutankhamun's tomb.

Oldest Nervous System Found in 520-Million-Year-Old Fossil

Fossils of an ancient creature resembling a shrimp with an armored head contain the oldest and best-preserved nervous system ever found, which could help scientists decipher the evolution of nervous systems in animals alive today, according to a new study. The remarkable remains belonged to Chengjiangocaris kunmingensis, a crustaceanlike creature that lived 520 million years ago in what is now South China. The fossils revealed a long "ropelike" central nerve cord that extended throughout the body, with visible clusters of nerve tissue arranged along the cord, like beads strung on a thread.
