Here's Why You Should Stop Using a smartphone to get more work done at night makes employees less productive the next day, new research suggests. Russell Johnson, a Michigan State University assistant professor of management and co-author of the study, said many smartphone owners consider the devices to be among the most important tools ever invented when it comes to increasing productivity of knowledge-based work. Yet, the National Sleep Foundation says only 40 percent of Americans get enough sleep on most nights and a commonly cited reason is smartphone usage for work. Both studies' surveys showed that nighttime smartphone usage for business purposes cut into sleep and sapped workers' energy the next day in the office.

To help those who are preparing for an upcoming interview put their best foot forward, Glassdoor sifted through tens of thousands of their interview reviews to find out some of the most common questions candidates are getting asked.

"Describe your strengths and what you bring to the table, but also ask a lot of questions about what the employer is looking for in a candidate to fill the position."

"Very often, societies have preferred male offspring, so when they practice infanticide, it tends to be the male babies that are kept, and the female babies that are killed," said study researcher Simon Mays, a skeletal biologist for English Heritage, a non-governmental organization that protects historic sites. Though ancient Romans indeed preferred boys, there is no evidence they went as far as infanticide to skew the sex ratio, Mays told LiveScience. Mays and his colleagues used a technique called ancient DNA analysis to study infant bones found at a site called Yewden Villa, near Hambleden, in England.

In the study, eight healthy people were injected with either lipopolysaccharide, a bacterial toxin that produces a strong immune response, or with salt water (which wasn't expected to have any effect).

NASA's Fermi telescope has captured the first gamma-ray measurements of a gravitational lens, a rare natural alignment in which a massive body distorts light from a more distant object. A team of international astronomers used the observatory to study the emission from one galaxy as its energetic emissions passed through another spiral galaxy on their way toward Earth. Fermi itself could even serve to identify more of these rare natural telescopes.

The  proposals are double the usual number submitted during such instrument competitions, NASA officials said. We truly appreciate this overwhelming response by the worldwide science and technical community and are humbled by the support and enthusiasm for this unique mission," John Grunsfeld, NASA's associate administrator for science, said in a statement. "We fully expect to be able to select an instrument suite that will return exciting science and advance space exploration at Mars," he added. Read More » Grand Canyon's Age? A Mix As Wild As the West The Colorado River took the easy route when it carved the Grand Canyon through Arizona's ruddy sandstones and pastel limestones, a new study claims. "I think the Colorado River found low places and paleocanyons and ancient topographies that led to the Grand Canyon," said Karl Karlstrom, lead study author and a geologist at the University of New Mexico in Albuquerque. But the study may do little to resolve the heated debate over the age of the Grand Canyon. For the past year, Karlstrom and others have stridently attacked work published Nov. 29, 2012, in the journal Science that suggested the westernmost Grand Canyon was 70 million years old. Read More »
