RIVERSIDE, Calif. -- Having a wider face helps men when they negotiate for themselves but hurts them when they are negotiating in a situation that requires compromise. Additionally, men who are more attractive are better collaborators compared to less attractive men.

This dipteran fly, therefore, serves as a potential vector of many diseases due to its close association with human dwellings. In general, C. megacephala is considered important in medical, veterinary and forensic sciences. Post mortem interval (PMI) determination is useful in cases of homicide, suicide and accidental or unattended death because of natural causes. An important aspect of calculating the PMI is the accurate and quick identification of the dipteran fly collected from a crime scene.
The drought that has the entire country in its grip is affecting more than the color of people's lawns. It may also be responsible for the proliferation of a heat-loving amoeba commonly found in warm freshwater bodies, such as lakes, rivers and hot springs, which the drought has made warmer than usual this year.
WOODS HOLE, MA -- What do mollusks, starfish, and corals have in common? Aside from their shared marine habitat, they are all calcifiers—organisms that use calcium from their environment to create hard carbonate skeletons and shells for stability and protection.
The July issue of The Biological Bulletin, published by the Marine Biological Laboratory, addresses the challenges faced by these species as ocean composition changes worldwide.
PASADENA, Calif., July 23, 2014 — More than 80 percent of hospitalized patients who tested positive for Clostridium difficile were tested outside the hospital or within the first 72 hours of hospitalization, suggesting that settings outside of the hospital may play key roles in the identification, onset and possible transmission of the disease, according to a new Kaiser Permanente study published today in the journal Mayo Clinic Proceedings.
Security forces worldwide rely on sophisticated equipment, trained personnel, and detection dogs to safeguard airports and other public areas against terrorist attacks. A revolutionary new electronic chip with nano-sized chemical sensors is about to make their job much easier.
Bethesda, MD (July 23, 2014) — Statins, a class of drugs commonly used to lower cholesterol levels, significantly reduce a patient's risk of developing Barrett's esophagus, according to a new study in Gastroenterology1, the official journal of the American Gastroenterological Association. Obese patients experienced the greatest level of risk reduction with statin use.
The popular culinary herbs oregano and rosemary are packed with healthful compounds, and now lab tests show they could work in much the same way as prescription anti-diabetic medication, scientists report. In their new study published in ACS' Journal of Agricultural and Food Chemistry, they found that how the herbs are grown makes a difference, and they also identified which compounds contribute the most to this promising trait.
As local and national governments struggle to deal with ever-growing piles of electronic waste (or "e-waste"), scientists are now refining the picture of just how much there is and where it really ends up. Published in the ACS journal Environmental Science & Technology, their study found that nearly a quarter of e-waste that developed countries discard floods into just seven developing countries — with major potential health risks for the people who live there.
By using brightly hued dyes, George Mason University researchers discovered an innovative way to reveal where proteins touch each other, possibly leading to new treatments for cancer, arthritis, heart disease and even lung disease.
A new study in East Asian women has identified three genetic changes linked to an increased risk of breast cancer. The research, led by Vanderbilt University investigators, was published online July 20 in Nature Genetics.
While breast cancer is one of the most common malignancies among women worldwide, most studies of the genetic risk factors for the disease have focused on women of European ancestry.
DNA has the nasty habit of getting tangled and forming knots. Scientists study these knots to understand their function and learn how to disentangle them (e.g. useful for gene sequencing techniques). Cristian Micheletti, professor at the International School for Advanced Studies (SISSA) in Trieste and his team have been carrying out research in which they simulate these knots and their dynamics.
Streptococcus mutans, one of the principal bacteria that cause dental caries, has increased the change in its genetic material over time, possibly coinciding with dietary change linked to the expansion of humanity. This is highlighted in a study by researchers from the Universitat Autònoma de Barcelona (UAB) and the Laboratorio Nacional de Genómica para la Biodiversidad (National Laboratory of Genomics for Biodiversity) in Mexico who, for the first time, have sequenced genetic material from this bacterium in populations from the past.
Intestinal parasites such as tapeworms, hookworms and a protist called Blastocystis can be beneficial to human health, according to a new paper that argues we should rethink our views of organisms that live off the human body.
To prove the point, paper co-author Julius Lukeš even ingested three developmental stages of a large species of tapeworm called Diphyllobothrium latum. After more than a year with the tapeworms, which might have grown to be as long as four metres each by now, he says he feels fine.
"I knew there was no risk," he says.
