Lifespan-Extending Drug Given Late in Life Reverses Age-Related Heart Disease in Mice
Elderly mice suffering from age-related heart disease saw a significant improvement in cardiac function after being treated with the FDA-approved drug rapamycin for just three months. The research, led by a team of scientists at the Buck Institute for Research on Aging, shows how rapamycin impacts mammalian tissues, providing functional insights and possible benefits for […] (Source: Biosingularity)

First Fluorescent Protein Identified in a Vertebrate Animal
The Japanese freshwater eel (Anguilla japonica) has more to offer biologists than a tasty sushi snack. Its muscle fibers produce the first fluorescent protein identified in a vertebrate, researchers report in Cell. Fluorescent proteins are as standard a tool for cell biologists as wrenches are for mechanics. They do not produce light themselves, but glow […] (Source: Biosingularity)

Dad ’s Life Stress Exposure Can Affect Offspring Brain
Sperm doesn’t appear to forget anything. Stress felt by dad—whether as a preadolescent or adult—leaves a lasting impression on his sperm that gives sons and daughters a blunted reaction to stress, a response linked to several mental disorders. The findings, published in a new preclinical study in the Journal of Neuroscience by researchers at the […] (Source: Biosingularity)

Hepatitis A and B
This 3D medical animation describes Hepatitis A and B. This animation begins by showing a healthy liver and explaining its function. The animation then goes on to explain the causes of Hepatitis A and B, how these viruses may be transmitted, the effects the virus can have on the liver as well as possible treatments. […] (Source: Biosingularity)

Mental block: scientists discover a way to alter memory
A series of studies conducted by an Iowa State University research team shows that it is possible to manipulate an existing memory simply by suggesting new or different information. The key is timing and recall of that memory, said Jason Chan, an assistant professor of psychology at Iowa State. “If you reactivate a memory by […] (Source: Biosingularity)
