Schizophrenia gene's role may be broader, more potent, than thought
Scientists have known that the mutated form of the human gene – one of three consistently associated with schizophrenia – mildly disrupts the transmission of chemical signals between nerve cells in th...

The authors of the new study, from Imperial College London, the University of Reading and the University of North Carolina, USA, argue that it is very unlikely that two genetic mutations would occur a...

Like all retroviruses, the AIDS virus (HIV) integrates its DNA into the genome of the infected cell. As integration sites, HIV usually prefers active genes that are transcribed frequently. This is adv...
Life Sciences | Read moreWhy can't chimps speak?
If humans are genetically related to chimps, why did our brains develop the innate ability for language and speech while theirs did not? Scientists suspect that part of the answer to the myste...
Studies and Analyses | Read moreAncient penguin DNA raises doubts about accuracy of genetic dating techniques
In other words, a biological specimen determined by traditional DNA testing to be 100,000 years old may actually be 200,000 to 600,000 years old, researchers suggest in a new report in Trends in Genet...

Paul Adams, assistant professor of chemistry and biochemistry, has received $108,000 over two years as part of the American Recovery and Reinvestment Act to hire two postdoctoral associates who will p...
Life Sciences | Read moreBacteria Expect the Unexpected
Organisms ensure the survival of their species by genetically adapting to the environment. If environmental conditions change too rapidly, the extinction of a species may be the consequence. A strateg...

While sedentary lifestyles and diets high in sugar and fat contribute significantly to the rise in diabetes rates, genetic factors may make some people more vulnerable than others to developing diabet...
Life Sciences | Read moreIs the disorder that causes dementia hereditary?
The brain disorder, called frontotemporal dementia, is formerly known as Pick's disease and destroys parts of the brain, leading to dementia, including problems with language or changes in behavi...
Studies and Analyses | Read moreTwo genes co-operate to cause aggressive leukaemia
The two genes are often present in mutated form in acute leukaemias, but the mutations rarely occur together. Scientists have previously believed that the two mutated genes have exactly the same funct...

In a study appearing in the October issue of Cancer Research, UT Southwestern researchers found that if they administered BEZ235 before they damaged the DNA of tumor cells with otherwise nontoxic radi...
Health and Medicine | Read moreScientists are first to observe the global motions of an enzyme copying DNA
Perpetuation of DNA mistakes can cause mutations that lead to cancer and other diseases.But before scientists can determine how and when errors are made during DNA replication, they must first...
