By Timothy T. Brown

It isn't uncommon for people to pass for ages much older or younger than their years, but researchers have now found that this feature doesn't apply to our brains. The findings reported online on August 16 in Current Biology, a Cell Press publicatio

Discovery of Immune Cells That Protect Against Multiple Sclerosis Offers Hope for New Treatment 2012-08-17

By Nir Yogev

In multiple sclerosis, the immune system attacks nerves in the brain and spinal cord, causing movement problems, muscle weakness and loss of vision. Immune cells called dendritic cells, which were previously thought to contribute to the onset and de

Turmeric Stopped Potentially Deadly Rift Valley Fever Virus from Multiplying in Infected Cells 2012-08-17

The popular spice turmeric packs more than just flavor -- it shows promise in fighting devastating viruses, Mason researchers recently discovered.

Metabolic Protein Wields Phosphate Group to Activate Cancer-Promoting Genes 2012-08-17

By Weiwei Yang

A metabolic protein that nourishes cancer cells also activates tumor-promoting genes by loosening part of the packaging that entwines DNA to make up chromosomes, a team led by scientists at The University of Texas MD Anderson Cancer Center reports i

Clear Links Found Between Inflammation, Bacterial Communities and Cancer 2012-08-17

By Janelle C. Arthur

What if a key factor ultimately behind a cancer was not a genetic defect but ecological? Ecologists have long known that when some major change disturbs an environment in some way, ecosystem structure is likely to change dramatically. Further,

Combination Peptide Therapies Might Offer More Effective, Less Toxic Cancer Treatment 2012-08-17

By Ohio State University Medical Center

Two studies suggest that two peptide agents used either together or individually with a low-dose of a standard chemotherapy drug might offer more effective cancer therapy than current standard single-drug treatments.

New Player in Immune Response? The Strange Case of UCP2 2012-08-17

By Anne Rupprecht

Uncoupling proteins present a paradox. They are found within mitochondria and serve to prevent the cell's powerhouses from exploiting the charge differential across their membranes to generate ATP, which the body uses as an energy source. When uncou

Molecular 'Movies' May Accelerate Anti-Cancer Drug Discovery 2012-08-17

By J. van Honk

Using advanced computer simulations, University of Utah College of Pharmacy researchers have produced moving images of a protein complex that is an important target for anti-cancer drugs. This advancement has significant implications for discovering
