Human-caused nitrogen deposition has been indirectly “fertilizing” forests, increasing their growth and sequestering major amounts of carbon, a new study suggests.

The findings create a more complex view of the carbon cycle in forests, where it was already known that logging or other stand-replacement events – whether natural or not – create periods of 5-20 years when there is a net release of carbon dioxide from forests to the atmosphere, instead of sequestration as they do later on.

A decade or so ago, a spate of high profile legal cases arose in which people were accused, and often convicted, on the basis of “recovered memories.” These memories, usually recollections of childhood abuse, arose years after the incident occurred and often during intensive psychotherapy.

So how accurate are recovered memories? The answer is not so clear. In fact, this question has lead to one of the most contentious issues in the fields of psychology and psychiatry.

As a result of mapping the structure of the protein complex implicated in autism spectrum disorders, a research team led by scientists at University of California, San Diego have discovered how particular genetic mutations affect this complex and contribute to the developmental abnormalities found in children with autism. Their work should help scientists pinpoint the consequences of other genetic abnormalities associated with the disorder.

If you've ever thought about running a public company, Sarbanes-Oxley is something you probably dread. Commonly dubbed "The Enron Law", it requires enormous oversight paperwork with the consequence that Chairmen, CEOs and Directors can go to jail if they violate it. A new University of Georgia study finds that the 2002 law has altered the makeup of corporate boards, making them larger and more independent and also had the unintended effect of increasing director pay - by more than 50 percent.

CEO pay as well. If you can go to jail for doing a job, be it Director or CEO, you demand more money to do it.

A new therapy to re-activate silenced genes in patients who suffer from neurodegenerative diseases or stroke is being developed by researchers at the University of Illinois at Chicago and Cornell University.

During and after a stroke, certain cellular events take place that lead to the death of brain cells. Compounds that inhibit a group of enzymes called histone deacetylases can modulate gene expression, and in some cases produce cellular proteins that are actually neuroprotective -- they are able to block cell death.

Human interaction and stimulation enhance chimpanzees’ cognitive abilities, according to new research from the Chimpanzee Cognition Center at The Ohio State University. The study (1) is the first to demonstrate that raising chimpanzees in a human cultural environment enhances their cognitive abilities, as measured by their ability to understand how tools work.
