Gene that controls sleep identified
Scientists have discovered a gene which they claim holds the key to the secret of an internal alarm clock which allows some people to get by on just four hours of sleep a night. A team at the Ludwig Maximilians University of Munich has identified the gene, called ABCC9,
Single Gene Defect Causes Brain Tumor
Pilocytic astrocytoma, the most common brain tumor in children, is usually slow-growing and benign. However, surgeons often cannot completely remove the diffusely growing tumor. This means that patients need further treatment in order to destroy remaining tumor tissue. Chemotherapy or radiation therapy can lead to severe side-effects and have only little effect on these slowly growing tumors.
Tweaking a Gene Makes Muscles Twice as Strong: New Avenue for Treating Muscle Degeneration in People Who Can't Exercise
An international team of scientists has created super-strong, high-endurance mice and worms by suppressing a natural muscle-growth inhibitor, suggesting treatments for age-related or genetics-related muscle degeneration are within reach.
The project was a collaboration between researchers at the Salk Institute for Biological Studies, and two Swiss institutions, Ecole Polytechnique Federale de Lausanne (EPFL) and the University of Lausanne. The scientists found that a tiny inhibitor may be responsible for
Junk DNA' Defines Differences Between Humans and Chimps
For years, scientists believed the vast phenotypic differences between humans and chimpanzees would be easily explained -- the two species must have significantly different genetic makeups. However,
Biologists Develop Genome-Wide Map Of MiRNA-mRNA Interactions
Researchers at New York University's Center for Comparative Functional Genomics and the University of California, Berkeley have used computational analyses to predict a genome-wide map of microRNA (miRNA) targets in the animal model organism, Caenorhabditis elegans (C.elegans).
