The 'Weakest Link' in the Aging Proteome

Salk Institute for Biological Studies

-Proteins are the chief actors in cells, carrying out the duties specified by information encoded in our genes. Most proteins live only two days or less, ensuring that those damaged by inevitable chemical modifications are replaced with new functional copies.

Lessons From the Worm: How the Elderly Can Live an Active Life

University of Michigan

When the tiny roundworm C. elegans reaches middle age—at about 2 weeks old—it can't quite move like it did in the bloom of youth. But rather than imposing an exercise regimen to rebuild the worm's body-wall muscles, researchers can bring the wriggle back by stimulating the animal's neurons. And, they say, pharmaceuticals might have a similar effect in mammals.

Tissue Loss Triggers Regeneration in Planarian Flatworms

Whitehead Institute for Biomedical Research

By investigating regeneration in planarian flatworms, Whitehead Institute researchers have identified a mechanism—involving the interplay of two wound-induced genes—by which the animal can distinguish between wounds that require regeneration and those that do not.

Study Examines Ways to Restore Immunity to Chronic Hepatitis C Infection

Nationwide Children's Hospital

The hepatitis C virus hijacks the body’s immune system, leaving T cells unable to function. A new study in animal models suggests that blocking a protein that helps the virus thrive could restore immune function, allowing the body to fight infection. The work, led by teams at The Research Institute at Nationwide Children’s Hospital and Emory University, was published online Aug. 26 in the Proceedings of the National Academy of Sciences.

Potential Epilepsy Drug Discovered Using Zebrafish

University of California, San Francisco (UCSF)

An antihistamine discovered in the 1950s to treat itching may also prevent seizures in an intractable form of childhood epilepsy, according to researchers at UC San Francisco who tested it in zebrafish bred to mimic the disease.

IT Monitoring Effective in Deterring Restaurant Fraud

Washington University in St. Louis

For many firms, losing significant revenue and profit to employee theft has been a cost of doing business. But a new study from Washington University in St. Louis finds that information technology monitoring is strikingly effective in reducing theft and fraud, especially in the restaurant industry.

'Negative Working Conditions Score' Linked to Depressive Symptoms

Journal of Occupational and Environmental Medicine

The sum total of adverse working conditions explains a substantial portion of the risk of depression in working-age adults, suggests a study in the September Journal of Occupational and Environmental Medicine, official publication of the American College of Occupational and Environmental Medicine (ACOEM).

New Evidence to Aid Search for Charge 'Stripes' in Superconductors

Brookhaven National Laboratory

Scientists at Brookhaven National Laboratory used an indirect method to detect fluctuating "stripes" of charge density in a material closely related to a superconductor. The research identifies a key signature to look for in superconductors as scientists seek ways to better understand and engineer these materials for future energy-saving applications.
