Unanticipated Link Found Between Cell Suicide and Long Life

Many health professionals believe that free radicals, the occasionally toxic molecules generated by the body as it processes oxygen, are the cause behind aging. However, a number of studies recently have generated evidence that the contrary may be true.  More...

Image An adeno-associated virus capsid (blue) modified by peptides (red) inserted to lock the virus is the result of research at Rice University into a new way to target cancerous and other diseased cells. The peptides are keyed to proteases overexpressed at the site of diseased tissues; they unlock the capsid and allow it to deliver its therapeutic cargo (Photo courtesy of Junghae Suh/Rice University).

Nanodelivery System Securely Targets Cancer cells

Scientists have devised a tunable virus that works similar to a safe deposit box. It takes two keys to open it and release its therapeutic payload.  More...

Brain Buffer System Overcomes Molecular Disturbances in Circadian Clock

New evidence has been found for neuronal network communication that helps create a behavioral buffer in the brain to overcome certain disturbances in the molecular level circadian clock rhythms.  More...

New Technique Developed for Species-Level Identification of Live Gram-Negative Bacteria

A new method has now been developed that specifically detects and identifies live Legionella pneumophila in aqueous samples much more quickly than conventional methods, enabling more effective monitoring to prevent epidemics.   More...

Image: Transmission electron microscopy (TEM) image of a single CVB3 virus showing tens of gold nanoparticles attached to its surface (left). The particles form a distinct “tagging pattern” that reflects the shape and the structure of the virus. The TEM image can be correlated to the model of the virus (right), where the yellow spheres mark the possible binding sites of the gold particles. The diameter of the virus is about 35 nm (Photo courtesy of PNAS - Proceedings of the National Academy of Sciences of the United States of America).

Mitochondrial Cause of Aging Can Be Reversed

Researchers have found a cause of aging in lab animals that can be reversed, possibly providing an avenue for new treatments for age-related diseases including type 2 diabetes, cancer, muscle wasting, and inflammatory diseases.   More...
