Astronauts get first look inside space station's new inflatable module

By Irene Klotz CAPE CANAVERAL, Fla. (Reuters) - Astronauts aboard the International Space Station on Monday floated inside an experimental inflatable module that will test a less expensive and potentially safer option for housing crews during long stays in space, NASA said. Station flight engineers Jeff Williams and Oleg Skripochka opened the hatch to the Bigelow Expandable Activity Module, or BEAM, at 4:47 a.m. EDT (0847 GMT) on Monday. Designed and built by privately-owned Bigelow Aerospace, BEAM is the first inflatable habitat to be tested with astronauts in space.

The Science of Football: Which Positions Take the Hardest Hits?

In a new study, researchers at the University of Michigan set out to answer that question. A race car braking and turning is under about 5 G's of force, said Dennis K. Lieu, a professor of mechanical engineering at the University of California, Berkeley, in an email interview with Live Science. The researchers found the running backs in the study — the men generally tasked with carrying the ball — experienced more "severe" impacts (above 10 G's) than all other offensive positions, although not a statistically significant number more than quarterbacks, according to the findings published May 21 in the Journal of Strength and Conditioning Research.

Why Pregnant Women Shouldn't Give In to Food Cravings

It may seem logical that if you crave certain foods during pregnancy, that craving is just your body's way of telling you what it needs. The more often women in the study gave in to such cravings, the more likely they were to gain too much weight during their pregnancy, according to the study, published May 20 in the journal Appetite. Previous research has shown that the more weight you gain during pregnancy, the harder it is to lose that weight after giving birth.

Workaholism Linked to ADHD and Depression

People who work too much may be more likely to have ADHD or depression, according to a new study from Norway. Researchers found that, among the workaholics in the study, nearly 33 percent had symptoms of ADHD, compared with about 13 percent of non-workaholics. For the study, workaholics were defined as those who met seven criteria, including whether they work so much that it has negatively influenced their health, or they feel stressed when they are prohibited from working.

Save the last dance for me: Being cute not enough for this spider when choosing a mate

A Sydney scientist has discovered seven new species of the tiny Australian peacock spider - a spectacularly colored, three-millimetre arachnid that dances to attract a female mate. Jurgen Otto, with the help of colleague David Knowles, made the two latest discoveries of the miniature creatures while looking for other spiders in Western Australia in November and had all seven named in the scientific journal Peckhamia last month.

Take the Moon Home with Incredibly Detailed Lunar Globe

If you want a nice view of the moon, instead of squinting into the night sky or cursing tall buildings, you could soon gaze at an expertly crafted model of the stunning celestial object. Its makers used NASA data to re-create the moon's many craters, including Petavius and Copernicus, at 1/20,000,000th the original size. The mini moon comes with a ring of LED lights that revolve around the globe and illuminate the face of the moon as seen from Earth.

Who Was Sattjeni? Tomb Reveals Secrets About Ancient Egyptian Elite

The coffin, discovered this year in the necropolis at Qubbet el-Hawa across the Nile River from Aswan, belonged to an important local woman, Sattjeni, daughter of one governor, wife of another and mother of two more, said excavation leader Alejandro Jiménez-Serrano, an Egyptologist at the University of Jaén in Spain. Sattjeni was not a royal, but her family practiced royal strategies to hold on to their governing power: She married her sister's widower, and the family also associated itself with the ram-headed deity Khnum, much as pharaohs intermarried to keep power in the family and claimed to be descended from the gods. In an email interview with Live Science, Jiménez-Serrano revealed more about the excavations at Qubbet el-Hawa and the life of Sattjeni.

Lost Underwater ‘City’ Revealed as Natural Geological Formation

Pipe-like, disc and doughnut-shaped structures discovered by underwater divers near the island of Zakynthos, Greece, were originally believed to be ruins of an ancient city, such as remnants of paved floors, courtyards and columns. Now researchers have found that the "ruins" are in fact geological formations, the results of a natural phenomenon that took place in the Pliocene epoch, up to 5 million years ago. Suspecting a geological explanation, the Greek Ministry brought in researchers from the University of East Anglia and the University of Athens to investigate the oddly shaped structures.

Males' Oversize Right Claw Lures Crustacean Ladies

If she's Dulichiella appendiculata — a tiny relative of the sand-hopping beach flea — she's impressed by the size of the male's enlarged right front claw, which is significantly bigger than its left one. And she definitely prefers righties to lefties. Scientists have investigated the mating success of right-clawed D. appendiculata males versus their left-clawed rivals, and found that righty males attracted more females.
