Some atoms don't always follow the rules. Take the beryllium dimer, a seemingly simple molecule made up of two atoms that University of Delaware physicists Krzysztof Szalewicz and Konrad Patkowski and colleague Vladimír Spirko of the Academy of Sciences of the Czech Republic report on in the Dec. 4 edition of the journal Science.
Human guinea pigs do their homework before volunteering for high-paying clinical trials. New research shows that people equate large payments for participation in medical research with increased levels of risk. And when they perceive studies to be risky, potential participants spend more time learning about the risks and nature of the study. Findings published this month in Social Science and Medicine, suggest there is a "mismatch" between current research guidelines for setting compensation levels and the assumptions participants make about the levels of pay and risk.
South Dakota State University researchers and their colleagues elsewhere in the U.S. and France found compelling evidence of a previously undocumented volcanic eruption that contributed to extremely cold decade from 1810-1819.

When you eat may be just as vital to your health as what you eat, found researchers at the Salk Institute for Biological Studies. Their experiments in mice revealed that the daily waxing and waning of thousands of genes in the liver—the body’s metabolic clearinghouse—is mostly controlled by food intake and not by the body’s circadian clock as conventional wisdom had it.
Nearly 90 percent of medical journals with relatively high impact factors have policies addressing author conflict of interest (COI) available for public review, according to a report in the November 25 issue of JAMA. But many journals do not require authors to sign disclosure statements, and there is variability in how COI is defined.

Last year, the United States overtook Germany to become the largest producer of wind energy in the world. This capped a five year expansion of U.S. wind power during which capacity increased by about a third every year.
When people speak, sing, or shout, they produce sound by pushing air over their vocal folds -- bits of muscle and tissue that manipulate the air flow and vibrate within it. When someone has polyps or some other problem with their vocal folds, the airflow can be altered, affecting the sound production.
A team of researchers at the Massachusetts Institute of Technology has developed a new modeling methodology for determining the capacity and assessing the risks of leakage of potential underground carbon-dioxide reservoirs.
A butterfly’s proboscis looks like a straw -- long, slender, and used for sipping -- but it works more like a paper towel, according to Konstantin Kornev of Clemson University. He hopes to borrow the tricks of this piece of insect anatomy to make small probes that can sample the fluid inside of cells.
Understanding mixing in the ocean is of fundamental importance to modeling climate change or predicting the effects of an El Niño on our weather. Modern ocean models primarily incorporate the effects of winds and tides. However, they do not generally take into account the mixing generated by swimming animals.
To design a lightweight anchor that can dig itself in to hold small underwater submersibles, Anette (Peko) Hosoi of MIT borrowed techniques from one of nature’s best diggers -- the razor clam.
A group of researchers at the City College of New York is developing a new way to generate power for planes and automobiles based on materials known as piezoelectrics, which convert the kinetic energy of motion into electricity.
