- Computers help chemists fight emerging infections
08-19-2007 · EurekAlert!
Computer analysis of existing drugs may be key to fighting new infectious agents and antibiotic-resistant pathogens like deadly tuberculosis strains and staph "superbugs." Researchers in Canada say the use of such "emergency discovery" technology could save time, money and lives during a sudden outbreak or a bioterrorism attack. The study will be presented in August at the American Chemical Society national meeting in Boston.

- Evolutionary battle scars' identify enhanced antiviral activity
01-24-2008 · EurekAlert!
Rapid evolution of a protein produced by an immunity gene is associated with increased antiviral activity in humans, a finding that suggests evolutionary biology and virology together can accelerate the discovery of viral-defense mechanisms, according to researchers at Fred Hutchinson Cancer Research Center in Seattle. These findings, published Jan. 25 in the open-access journal PLoS Genetics, present a striking example by which evolutionary studies can directly lead to biomedically important discoveries in the field of infectious diseases.

- Buildup of damaged DNA in cells drives aging
12-20-2006 · EurekAlert!
A study being published today in the journal Nature found that mice completely lacking a critical gene for repairing damaged DNA grow old rapidly and have physical, genetic and hormonal profiles very similar to mice that grow old naturally. Furthermore, the premature aging symptoms of the mice led to the discovery of a new type of human progeria, a rare inherited disease in which affected individuals age rapidly and die prematurely.

- New use for stem cells found in war on terrorism
09-25-2007 · EurekAlert!
For more than a decade, Steve Stice has dedicated his research using embryonic stem cells to improving the lives of people with degenerative diseases and debilitating injuries. His most recent discovery, which produces billions of neural cells from a few stem cells, could now aid in national security. In collaboration with the US Naval Research Laboratory, Stice hopes to use his recently developed neural cell kits to detect chemical threats.

- 'GreeneChip' -- New diagnostic tool that rapidly and accurately identifies multiple pathogens
12-06-2006 · EurekAlert!
Researchers in the Greene Infectious Disease Laboratory at Columbia University's Mailman School of Public Health and their colleagues in the WHO Global Laboratory Network have developed a new tool for pathogen surveillance and discovery -- the GreeneChip System. The GreeneChip is the first tool to provide comprehensive, differential diagnosis of infectious diseases, including those caused by viruses, bacteria, fungi or parasites.
