Scientists Identify New Breast Cancer Gene

US researchers say that they have identified a gene that needs to be investigated as a possible breast cancer gene in future studies. The gene detected by the researchers is Rap80, which is required for the norm...

Scientist Observes real Time Generation of Neurones in Mammals

...icroscopic imaging techniques, combined with virus gene technology. The dendrites are the string-like extensions of the neurone that spread out to reach other neurones, and serve as the points of communication between them. The model employed in the research was the new-born neurone population which...

Scientist Found New Mechanism for Brain Learning

...d to learn, said Dr. Bibb. "Being able to turn a gene off throughout a brain is a really advanced thing to do. Its been shown that it can be done, but we put the system together and actually applied it," he said. Since Cdk5 is heavily implicated in Alzheimers disease and addiction to drugs of abuse, D...

"(Dr. Mei's) findings help explain how a gene that is potentially causative in disorders like schizophrenia and bipolar disorder relate to a neurotransmitter that is critical for explaining the cognitive deficits associated with the illness," says Dr. Daniel R. Weinberger, director of the Genes,...

Scientists Identify Four Genes That Raise the Risk of Breast Cancer

...aid that the technique should speed up the rate of gene identification enormously for a range of cancers. "Previously scientists have had to search for new cancer genes one at a time, but we have been able to search two thirds of the genome in one go," Times Online quoted him as saying. "Rather than ...

Natural Compound in Grapes, Tea and Cocoa Helps to Enhance Memory

...n showed enhanced memory, blood vessel growth, and gene activity during the study, such benefits were even more evident in mice that also exercised. "A logical next step will be to study the effects of epicatechin on memory and brain blood flow in aged animals, and then humans, combined with mild exerci...
