Penn State researchers and their collaborators have made a discovery that could lead to new treatments for HIV, the Human Immunodeficiency Virus that causes AIDS. Knocking out a particular enzyme (a tyrosine kinase) makes immune cells less vulnerable to infection with the virus. » full article

Tropical reservoir for human influenza?

Analysis of more than 1300 complete genomes of human influenza A suggests that new viral strains arise in a reservoir in the tropics, and move out to temperate regions. » full article

Alcohol addiction and sex in flies

A PLoS One paper by Penn State researchers reports how chronic alcohol exposure makes male fruit flies more likely to court females and other males. Perhaps unsurprisingly, this study has attracted a lot of media interest. » full article

New MRI capabilities

Penn State has purchased two whole-body magnetic resonance imaging (MRI) systems. One will be housed on the University Park campus and the other at the College of Medicine. The new University Park system will be based in Moore Building and is expected to become operational in summer 2008. » full article

Why is 'flu seasonal?

In temperate regions, winter is the season for 'flu. Annual influenza epidemics hit the northern hemisphere between November and March, and the southern hemisphere from May to September. Together with collaborators at the National Institutes of Health, Penn State researchers have now found evidence that the global migration of viruses is responsible for this seasonality. Their findings suggest that even in geographically-isolated places like New Zealand, epidemics are triggered by viruses arriving from elsewhere in the world, rather than by reactivation of viruses that have remained latent in hosts, or that have been transmitting locally at low levels. » full article

Enzyme-deficient mice are less fat

College of Medicine scientists and their collaborators have discovered that mice deficient in a particular enzyme are leaner than normal mice even though they eat more food. In a paper in Cell Metabolism, they show that the enzyme-deficient mice appear to burn extra calories through a "futile" cycle of protein synthesis and breakdown. These findings could potentially lead to new weight-loss therapies. » full article

Mammoth discovery

The field of ancient DNA has seen a major breakthrough. An international team of researchers led by Stephan C. Schuster and Webb Miller of The Pennsylvania State University has developed a way of isolating DNA from extremely old hair, rather than from fossil bones. They used this method to recover the mitochondrial genomes of ten woolly mammoths dug out of the Siberian permafrost during the last 200 years; the mammoths died between 12,000 and 50,000 years ago. The publication of their genetic sequences in the journal Science more than doubles the number of published mitochondrial genomes from extinct animals, and opens the way to further study of species only known from museum specimens. » full article

Undergraduate wins ASPB Fellowship

Charles Mason won a $3000 fellowship from the American Society of Plant Biologists (ASPB). Mason was one of just 15 students nationwide selected for the fellowship, which also includes student membership in the ASPB and a travel grant to attend the 2008 ASPB Plant Biology meeting. » full article
