Short-legged Oregon arachnid gets 'behemoth' name

By Courtney Sherwood PORTLAND, Ore. (Reuters) - Researchers have bestowed a grandiose scientific name on a tiny, spider-like cousin of the daddy longlegs, officially dubbing the newly discovered denizen of remote Oregon forests the Cryptomaster behemoth. The diminutive, short-legged arachnid made its published debut late last month in the peer-reviewed scientific journal ZooKeys, where San Diego State University biologists who made the discovery first described it. Like the daddy longlegs, which is commonly but mistakenly referred to as a spider, the Cryptomaster behemoth actually belongs to an order of arachnids called Opiliones, or harvestmen.

Russian cosmonauts breeze through spacewalk outside space station

By Irene Klotz CAPE CANAVERAL, Fla. (Reuters) - Two veteran Russian cosmonauts returned to the International Space Station on Wednesday after replacing experiment equipment that is testing how materials and biological samples fare in the harsh environment of space. Station flight engineers Yuri Malenchenko and Sergey Volkov left the station's airlock at 7:55 a.m. EST (1255 GMT) for what was expected to be a 5-1/2-hour spacewalk, a live broadcast on NASA Television showed. Malenchenko and Volkov began their spacewalk by casting off a flash drive into space, giving a ceremonial send-off to recorded messages and video from last year’s 70th anniversary of Victory Day, said NASA mission commentator Rob Navias.

U.S. private space companies plan surge in launches this year

U.S. private space companies Space Exploration Technologies and United Launch Alliance, a partnership of Lockheed Martin and BoeingN , have scheduled more than 30 launches from Florida this year, up from 18 last year, according to company and Air Force officials. The jump in planned launches reflects increasing demand for commercial communications and imaging satellites, as well as business from the U.S. military, International Space Station cargo ships and a NASA asteroid sample return mission.

Smart band-aid on the horizon

By Ben Gruber Cambridge, MASS (Reuters) - Wearable electronics will revolutionize the way doctors diagnose and treat patients, according to researchers at MIT, who are developing stretchable hydrogels that share many of the same properties of human tissue. "Hydrogel is a polymer network infiltrated with water.

Human Brain's Bizarre Folding Pattern Recreated in a Vat

Scientists have discovered exactly how the human brain gets its crinkly, wrinkly appearance in utero. It turns out that the huge explosion in the number of brain cells in the brain's outer layer, called the cortex, forces that layer to swell and then collapse in on itself to form those characteristic creases. "This simple evolutionary innovation, with iterations and variations, allows for a large cortex to be packed into a small volume, and is likely the dominant cause behind brain folding, known as gyrification," said study co-author L. Mahadevan, an applied mathematician at Harvard University.

Why Sand Tiger Shark Devours Aquarium Mate (Video)

Any sharks that want to enhance their reputation as fearsome predators should follow the lead of a sand tiger shark at the Coex Aquarium in Seoul, South Korea, that surprised aquarium goers by devouring a fellow shark — and taking nearly a day to finish the job. This sand tiger shark (not to be confused with a tiger shark) is an 8-year-old female, measuring 7.22 feet (2.2 meters) long, Reuters reported. "It's unfortunate anytime you see something like that, regardless of what the circumstances are," said Chris Plante, assistant curator at the Aquarium of the Pacific, after viewing the video at Live Science's request.

Spacewalking Russian cosmonauts begin work outside space station

By Irene Klotz CAPE CANAVERAL, Fla. (Reuters) - Two veteran Russian cosmonauts floated outside the International Space Station on Wednesday to replace experimental equipment that is testing how materials and biological samples fare in the harsh environment of space. Station flight engineers Yuri Malenchenko and Sergey Volkov left the station's airlock at 7:55 a.m. EST for what was expected to be a 5-1/2-hour spacewalk, a live broadcast on NASA Television showed.

Meet 'Squishy Fingers': Flexible Robot Advances Undersea Research

Meet "Squishy Fingers," a new remotely operated vehicle designed to delicately grab and take samples of coral. The ROV, described in a Jan. 20 study in the journal Soft Robotics, will help researchers collect specimens from deep underwater reefs without damaging the corals' fragile bodies. "If we're going to go down and study these systems, then we should be as gentle as we possibly can," said study co-senior author David Gruber, an associate professor of biology at Baruch College in New York City and a National Geographic emerging explorer.

Small country, big Universe - Luxembourg aims for space business

By Meredith McGrath BRUSSELS (Reuters) - Luxembourg, the tiny European Union state nestled between France, Germany and Belgium, has a big new goal - it wants to be a center for space mining. Primarily known for its fund management and private banking industry, the duchy is promoting a law that would make it the first in Europe to give legal clarity to the commercial exploitation of asteroids. "In the long-term, space resources could lead to a thriving new space economy and human expansion into the solar system," Etienne Schneider, Luxembourg's economy minister told a press conference.

How Zika Virus Spreads: Chain of Events Explained

Zika virus is "now spreading explosively in the Americas," World Health Organization (WHO) Director-General Dr. Margaret Chan said on Thursday (Jan. 28), and 3 million to 4 million people in the Americas could be infected by the virus this year alone, according to the latest WHO estimates. However, U.S. officials have said that the virus is likely to cause only small outbreaks in this country. To understand how the Zika virus spreads to new regions, and how researchers can tell whether a region is likely to experience large outbreaks or small ones, Live Science asked the experts what sequence of events has to happen in order for the virus to become established in a new region.

Sexually Transmitted Zika Case Confirmed in Texas

A person in Dallas appears to have spread the Zika virus to another person through sex, Texas health officials said today. Officials at Dallas County Health and Human Services (DCHHS) said that a person in the area was infected with the Zika virus after having sexual contact with another person who had returned from Venezuela, where the virus is spreading, and was ill. "Now that we know Zika virus can be transmitted through sex, this increases our awareness campaign in educating the public about protecting themselves and others," Zachary Thompson, the DCHHS director, said in a statement.

Map of Winter Storm Jonas' Wind Shows Destructive Gusts

Winter storm Jonas brought with it record-breaking amounts of snow and blustering winds when it plowed through the northeastern and mid-Atlantic United States in late January. Now, scientists at NASA have created a new map showing the direction and speeds of the massive storm's wind gusts.

Smartphones Could Generate Own Power with New Coating

A transparent material that can be attached to a smartphone's touch screen could help the device generate electricity whenever anyone taps it, researchers in China say. Touch screens are now found on most cell phones and tablet computers. Using a touch screen typically involves finger taps, and scientists at Lanzhou University in China reasoned that the mechanical energy from these motions could be converted into electricity to charge the phone's batteries, which could significantly extend the working time of these portable devices.

Massive Bird Die-Off Puzzles Alaskan Scientists

Thousands of dead seabirds have washed up on Alaskan shores over the past nine months. Nearly 8,000 common murres (Uria aalge) were found along the shores of Whittier, Alaska, in early January. Over the New Year's holiday, Alaska experienced four days of gale-force winds from the southeast that resulted in dead birds washing ashore, said Robb Kaler, a wildlife biologist for the Alaska branch of the U.S. Fish and Wildlife Service (USFWS).

Scientists' path to usable Zika vaccine strewn with hurdles

Making a shot to generate an immune response against Zika virus, which is sweeping through the Americas, shouldn't be too hard in theory. For a start, scientists around the world know even less about Zika than they did about the Ebola virus that caused an unprecedented epidemic in West Africa last year. Ebola, due to its deadly power, was the subject of bioterrorism research, giving at least a base for speeding up vaccine work.
