"There is a strong contemporary association between high heels and female sexuality. We investigated the hypothesis that one motivation for women wearing high heels is that it artificially increases the femininity of gait. Biomechanical analyses revealed that wearing high heels led to increased femininity of gait including reduced stride length and increased rotation and tilt of the hips. This groundbreaking study was published this month in the scientific journal Evolution and Human Behavior. It was written by Paul H. Morris, Jenny White, Edward R. Morrison and Kayleigh Fisher"

Droplet network printer ""We aren't trying to make materials that faithfully resemble tissues, but rather structures that can carry out the functions of tissues," said Professor Hagan Bayley of Oxford University's Department of Chemistry, who led the research. "We've shown that it is possible to create networks of tens of thousands of connected droplets. The droplets can be printed with protein pores to form pathways through the network that mimic nerves and are able to transmit electrical signals from one side of a network to the other.""

The vision of a national digital library has been circulating among librarians, scholars, educators, and private industry representatives since the early 1990s, but it has not yet materialized. Efforts led by a range of organizations, including the Library of Congress, HathiTrust, and the Internet Archive, have successfully built resources that provide books, images, historical records, and audiovisual materials to anyone with Internet access. Many universities, public libraries, and other public-spirited organizations have digitized materials that could be brought together under the frame of the DPLA, but these digital collections often exist in silos.

"For 20 years, researchers have reported a potential link between gum disease and atherosclerotic heart disease from hardening of the arteries or stroke. "The message sent out by some in health-care professions, that heart attack and stroke are directly linked to gum disease, can distort the facts, alarm patients and perhaps shift the focus on prevention away from well-known risk factors for these diseases," said Dr. Peter Lockhart, a professor and chair of oral medicine at the Carolinas Medical Center in Charlotte, N.C. Lockhart wrote the heart group's new position statement in the journal Circulation. The statement was prepared after a three-year analysis of about 600 studies by an expert panel led by a dentist and a cardiologist."

""We wondered how individuals assess the credibility of other people in simple social interactions," said Read Montague, director of the Human Neuroimaging Laboratory and the Computational Psychiatry Unit at the Virginia Tech Carilion Research Institute, who led the study. "We found a strong correlation between the amygdala and a baseline level of distrust, which may be based on a person's beliefs about the trustworthiness of other people in general, his or her emotional state, and the situation at hand"

"explains how nitric oxide, a signaling molecule involved in the immune system, leads to biofilm formation. "It is estimated that about 80 percent of human pathogens form biofilms during some part of their life cycle," said Scripps Research president and CEO Michael Marletta, PhD, who led the work."

""We probably have underestimated the role our microbial flora play in modulating disease risk," says Daniel Rader, a heart disease specialist at the University of Pennsylvania School of Medicine. Rader, who was not involved in the study, says that gut bacteria may not be as big a factor in causing heart disease as diabetes or smoking, but could be important in tipping some people toward sickness. Researchers led by Stanley Hazen, a cardiologist at the Cleveland Clinic, didn't start out to study gut bacteria. In fact, says Hazen, he had "no clue - zero," that intestinal microbes were involved in heart disease. "I'd never even considered it or thought of the concept." Hazen and his colleagues compared blood plasma from healthy people to plasma from people who had had heart attacks, strokes or died to see if substances in the blood could predict who is in danger from heart disease. The researchers found 18 small molecules associated with fat buildup in the arteries. One of the best predictors turned out to be a byproduct made when gut bacteria break down a fat called choline (also known as lecithin). The more of this byproduct, called trimethylamine N-oxide or TMAO, a person or mouse has in the blood, the higher the risk of getting heart disease, the researchers found. Gut bacteria are actually middlemen in TMAO production. The microbes convert lecithin to a gas that smells like rotten fish. Then an enzyme in the liver changes the foul-smelling gas to TMAO."

"Alternatively, the technique could potentially be used to insert cells directly into damaged retinas during ocular surgery, says Keith Martin, a professor of ophthalmology at the University of Cambridge, who led the research."

ScienceDaily (June 28, 2010) - An Australian National University-led team has developed the most efficient quantum memory for light in the world, taking us closer to a future of super-fast computers and communication secured by the laws of physics.

By working with the simplest amino acids and elementary RNAs, physicists led by Rockefeller University's Albert J. Libchaber, head of the Laboratory of Experimental Condensed Matter Physics, have now generated the first theoretical model that shows how a coded genetic system can emerge from an ancestral broth of simple molecules.

Exquisite measurements of the radiation left over from the big bang led us to believe that we could work out the curvature of the universe to within a few per cent. In doing so, we have determined how much energy the universe contains and that most of it is in an exotic form called dark energy, which is driving the expansion of space. However, recent discoveries have left me wondering if these claims were premature. As we learn more about dark energy and its effect on the expansion of space and time, we find that dark energy and the shape, or geometry, of the universe are worryingly intertwined.

As someone who's researched dark matter extensively, it is my determination that dark matter most likely exists, although explaining exactly what it is is a challenge. Over this next series, I would like to lead you through the evidence, observations and discoveries that have led me to this conclusion, and I hope that I explain this well enough that it leads you to draw the same ones for yourself.

"ScienceDaily (Aug. 31, 2010) - There's something beyond plain old ignorance that motivates Americans to believe President Obama is a Muslim, according to a first-of-its-kind study of smear campaigns led by a Michigan State University psychologist."

The shrinking of the transistor has approached fundamental physical limits. Increasingly, transistor manufacturers grapple with subatomic effects, like the tendency for electrons to "leak" across material boundaries. The leaking electrons make it more difficult to know when a transistor is in an on or off state, the information that makes electronic computing possible. They have also led to excess heat, the bane of the fastest computer chips.

"Iowa State University Distinguished Professor of Psychology Craig Anderson has made much of his life's work studying how violent video game play affects youth behavior. And he says a new study he led, analyzing 130 research reports on more than 130,000 subjects worldwide, proves conclusively that exposure to violent video games makes more aggressive, less caring kids -- regardless of their age, sex or culture."
