Chemists at Syracuse University have figured out how to synthesize nanomaterials with stainless steel-like interfaces. Their discovery may change how the form and structure of nanomaterials are manipulated, particularly those used for gas storage, heterogeneous catalysis and lithium-ion batteries. Fuente :...

New research on two promising gene therapies suggests that combining them into one treatment not only repairs muscle damage caused by Duchenne muscular dystrophy, but also prevents future injury from the muscle-wasting disease. The work, led by a team at The Research Institute at Nationwide Children's Hospital, is the first to...

A unique nanoscale drug that can carry a variety of weapons and sneak into cancer cells to break them down from the inside has a new component: a protein that stimulates the immune system to attack HER2-positive breast cancer cells. Fuente : http://www.eurekalert.org/pub_releases/2013-08/cmc...

There are known risks for and protective factors against the development of alcohol use disorders (AUDs). A new study has found that striatal dopamine responses to alcohol ingestion may serve as a neurobiological marker of vulnerability to AUDs.Specifically, when given alcohol, those at high risk showed an increase in brain...

Research from McGill University suggests that people who are vulnerable to developing alcoholism exhibit a distinctive brain response when drinking alcohol, according to a new study by professor Marco Leyton, of McGill University's Department of Psychiatry. Compared to people at low risk for alcohol-use problems, those at high...

The Black Forest wildfire this June was one of the most destructive in Colorado history, in terms of homes lost. It started close to houses and quickly spread through the ponderosa pine canopies on the rolling hills near Colorado Springs. The wildfire destroyed 500 homes in the first 48 hours and killed two people. Fuente :...

New research describes the dynamics of DNA methylation across a wide range of human cell types. Chemically, these marks are the addition of a methyl group -- one carbon atom surrounded by three hydrogen atoms -- anywhere a cytosine nucleotide sits next to a guanine nucleotide in the DNA sequence....
