Micro RNAs play role in egg making

...nding to genetic elements called messenger RNA and preventing them from making new proteins -- the molecules primarily responsible for cell activities. While previous research has identified some miRNA targets, investigators haven't yet seen how they impact developmental processes. "We found the first evidenc...

DDT-resistant insects have additional genetic advantage that helps resistance spread

...ntage to 'superbug' bacteria, and measures such as preventing certain antibiotics from being prescribed may not halt the spread of antibiotic resistance in bacteria. "We found that DDT resistance in fruit flies not only carries no cost but in fact confers an advantage when inherited through the female," said R...

Tiny roundworm's telomeres help scientists to tease apart different types of aging

...PLoS Genetics, available online now. In the past, preventing telomere shortening has often been portrayed as the key to preventing aging and living longer. In their study, Salk scientists Jan Karlseder, an assistant professor in th...

Newly recognized gene mutation may reduce seeds, resurrect plants

... Purdue plant physiologist. Lipids play a role in preventing plant dehydration in forming cells' membranes, in molecular signaling and in energy storage. A still-to-be revealed lipid associated with formation of the cuticle that coats plant surfaces may signal whether a seed develops to maturity or is aborted ...

Preventing a pandemic: Study suggests strategies for containing a flu outbreak

... in humans, there is a chance of containing it and preventing a pandemic. However, it will require a serious effort, with major planning and coordination, and there is no guarantee of success," said coauthor Elizabeth Halloran of Emory University. "Early intervention could at least slow the pandemic, helping t...

Complex gene interactions account for autism risk

...em therefore acts as a sort of information filter, preventing the brain from becoming over-stimulated, the researchers explained. "Impairing the GABA system could overwhelm the brain with sensory information, leading to both the behavior and the pattern of cell damage that emerges in autism," said John Hussman...
