Surprising discovery about the inner workings of vesicular stomatitis virus

Biochemists at Wake Forest University School of Medicine have made a surprising discovery about the inner workings of a powerful virus - a discovery that they hope could one day lead to better vaccines or anti-virus medications.

Scientists discover structure of malaria defense process

Scientists from two universities in Italy and Virginia Tech in the United States have determined the structure of a protein that is responsible for the production xanthurenic acid (XA) in Anopheles gambiae, the malaria carrying mosquitoes.

Cancer virus protein p13 needed for successful infection and reproduction

New research shows that a protein made by a cancer-causing virus that was thought to be unimportant for its replication is in fact critically needed by the virus to initiate an infection and to reproduce.

Dysregulation of the Hedgehog pathway in human hepatocarcinogenesis

The unchecked activity of a cell signaling pathway crucial in embryonic development and the liver's response to injury leads to liver cancer, researchers from Duke University Medical Center and John Hopkins University School of Medicine have found.

Procedure cures some diabetic mice, but not in the way previously reported

Researchers attempting to reproduce a controversial 2003 mouse experiment suggestive of a cure for type 1 diabetes have found evidence that the experimental procedure does eliminate diabetic symptoms in a small fraction of the mice exposed to it.

Divergent behavioral roles of angiotensin receptor intracellular signaling cascades

Researchers at the University at Buffalo and the University of Pennsylvania were the first to demonstrate that two intracellular events, both stimulated by the same cell receptor, can provoke different behaviors in mammals.

Smk-1 is the first known gene that regulates longevity without disrupting life-sustaining function

Within a hormone-triggered cascade of molecular signals that plays a crucial for a wide range of physiological functions, researchers for the very first time have identified a protein that functions specifically to extend lifespan and youthfulness - without disrupting fertility

A map of recent positive selection in the human genome

By scanning the entire human genome in search of genetic variations that may signal recent evolution, University of Chicago researchers found more than 700 genetic variants that may be targets of recent natural positive selection during the past 10,000 years of human evolution.

Nematode hormone discovery may aid fight against parasitic disease

New research at UT Southwestern Medical Center shows that on a biochemical level, hormone-like molecules in tiny worms called nematodes work similarly to the way in which certain hormones work in humans - findings that one day may help eradicate worm infections that afflict a third of the world's population.

Scientists create a mosquito resistant to Type 2 dengue fever virus

Researchers have successfully created a genetically engineered mosquito that shows a high level of resistance against the most prevalent type of dengue fever virus, providing a powerful weapon against a disease that infects 50 million people each year.

Cost of sexuality in microbes

The next time you mutter about the high cost of relationship maintenance, take comfort in knowing that microbes share your pain.

Hormone discovered in bird brains also plays major role in mammalian reproductive system

University of California, Berkeley, researchers have discovered a new actor in the mammalian reproductive system, a hormone that fills a role long suspected, but until now undetected.

New method to find new metabolites

Ever since penicillin, a byproduct of a fungal mold, was discovered in 1929, scientists have scrutinized fungi for other breakthrough drugs. As reported Jan. 20 in the Journal of Chemistry and Biology, a team led by a University of Wisconsin-Madison researcher has developed a new method that may speed the ongoing quest for medically useful compounds in fungi.

Face perception is mediated by a distributed neural system in the human brain

New research indicates that an area of the brain thought to act in reward circuitry may represent a phase in visual processing during which sexual orientation modulates how we perceive individual faces. The findings are reported by Felicitas Kranz and Alumit Ishai of the University of Zurich.

Chlamydia loves lipid droplets

Invasive bacterial pathogens, the Chlamydiae know us very, very well. The Chlamydiae learned to parasitize eukaryotic cells half a billion years ago by reprogramming cellular functions from within.

Fast-tracked screening for Chlamydia in UK

Young women asking for the morning-after pill at pharmacies will be offered fast-tracked screening for Chlamydia, the UK's most common sexually transmitted infection, in a University of Manchester study.

Young women asking for the morning-after pill at UK pharmacies will be offered fast-tracked screening for Chlamydia

It is thought that up to one in ten young people under 25 have Chlamydia, a sexually transmitted infection that often has no symptoms and can lead to infertility, although it is very easily treated with just one dose of four tablets in the majority of cases.
