Fetal alcohol spectrum disorder (FASD) and Fetal alcohol syndrome (FAS) cause malformations in babies, including facial defects, short stature, and mental and behavioral abnormalities. The African frog, Xenopus, is a valuable tool for understanding early vertebrate development since these embryos are large, easy to work with and very responsive to environmental cues. New research uses [...]

Scientists learn why the flu may turn deadly
As the swine flu continues its global spread, researchers from the Children’s Hospital of Philadelphia, Pennsylvania, have discovered important clues about why influenza is more severe in some people than it is in others. In their research study published online in the Journal of Leukocyte Biology (http://www.jleukbio.org), the scientists show that the influenza virus can [...]

PHILADELPHIA – Three-day-old broccoli sprouts, a widely available human food, suppressed Helicobacter pylori (H. pylori) infections, according to a report in Cancer Prevention Research, a journal of the American Association for Cancer Research. H. pylori infections are one of the most common bacterial infections worldwide and are a major cause of stomach cancer. The cancer [...]
CHAMPAIGN, Ill. — Chemists at the University of Illinois have created a simple and inexpensive molecular technique that replaces an expensive atomic force microscope for studying what happens to small molecules when they are stretched or compressed. The researchers use stiff stilbene, a small, inert structure, as a molecular force probe to generate well-defined forces [...]
Increased schooling across sub-Saharan Africa may be lowering new HIV infections among younger adults, according to sociologists, suggesting a shift in a decades-long trend where formal education is considered an AIDS risk factor. While education in general has a positive impact on global public health, when it comes to HIV and AIDS in sub-Saharan Africa, [...]
Silvia Ferrari is assistant professor of mechanical engineering and materials science at Duke’s Pratt School of Engineering. Credit: Duke University DURHAM, N.C. — Scientists have used a popular kids swimming pool game to guide their development of a system for controlling moving robots that can autonomously detect and capture other moving targets. Engineers from Duke [...]
Caption: Researchers at Rensselaer Polytechnic Institute have discovered a new method for growing slimmer copper nanorods, which can be used as a low-temperature bonding agent for holding together the layers of next-generation 3-D integrated computer chips. The researchers found that interrupting the nanorod growth process results in thinner rods. Pictured are scanning electron images, at [...]
Dangling a lucrative financial carrot at the end of a professional sport season can cause certain players to exert the effort necessary to put together a string of successful performances, sometimes known in sporting circles as a “hot hand” or “hot streak.” That’s the result of a forthcoming study by North Carolina State University economists [...]
They say a picture tells a thousand stories, but can it also tell how smart you are? Actually, say UCLA researchers, it can. In a study published in the Journal of Neuroscience Feb. 18, UCLA neurology professor Paul Thompson and colleagues used a new type of brain-imaging scanner to show that intelligence is strongly influenced [...]
