Scientists See Brain Aging Before Symptoms Appear
UCLA scientists have used innovative brain-scan technology developed at UCLA, along with patient-specific information on Alzheimer's disease risk, to help diagnose brain aging, often before symptoms appear. Published in the January issue of Archives of General Psychiatry, their study may offer a more accurate method for tracking brain aging.

Physical Activity May Not Be Key To Obesity Epidemic
A recent international study fails to support the common belief that the number of calories burned in physical activity is a key factor in rising rates of obesity. Researchers from Loyola University Health System and other centers compared African American women in metropolitan Chicago with women in rural Nigeria.

Differentiating Between Healthy Cells And Cancer Cells
One of the current handicaps of cancer treatments is the difficulty of aiming these treatments at destroying malignant cells without killing healthy cells in the process.

Majority Of Teens Discuss Risky Behaviors On MySpace, Studies Conclude
In a pair of related studies released by Seattle Children's Research Institute and published in the January 2009 issue of Archives of Pediatric & Adolescent Medicine, researchers found that 54 percent of adolescents frequently discuss high-risk activities including sexual behavior, substance abuse or violence using MySpace, the popular social networking Web site (SNS).

Number Of Babies Exposed To Drugs Effectively Reduced By 'Recovery Coaches'
About 11 percent of the 4 million babies born in the U.S. each year have been exposed to alcohol or illicit drugs in the womb, according to a June 2006 report by the National Center on Substance Abuse and Child Welfare. If removed from the home by child protection, these children tend to remain in foster care longer, and chances are very low that they will be reunited with their parents.

New Tumor Suppressor For Lung Cancer Identified By Cell Biologists
Cancer and cell biology experts at the University of Cincinnati (UC) have identified a new tumor suppressor that may help scientists develop more targeted drug therapies to combat lung cancer. The study, led by Jorge Moscat, PhD, appears in the January 2009 issue of Molecular and Cellular Biology.

Stanford/UCSF Study Shows That Testes Stem Cell Can Change Into Other Body Tissues
Scientists at the Stanford University School of Medicine and at UC-San Francisco have succeeded in isolating stem cells from human testes. The cells bear a striking resemblance to embryonic stem cells - they can differentiate into each of the three main types of tissues of the body - but the researchers caution against viewing them as one and the same.

Improved Understanding Of Complex Mechanisms That Regulate DNA Damage Control And Replication In The Cell Cycle
Scientists at Burnham Institute for Medical Research (Burnham) have demonstrated important new roles for the protein kinase complex Cdc7/Dbf4 or Cdc7/Drf1 (Ddk) in monitoring damage control during DNA replication and reinitiating replication following DNA repair.

"On Switch" For Cell Death Signaling Mechanism Discovered By Burnham Researchers
Scientists at Burnham Institute for Medical Research (Burnham) have determined the structure of the interactions between proteins that form the heart of the death inducing signaling complex (DISC), which is responsible for triggering apoptosis (programmed cell death). The research, performed by Stefan Riedl, Ph.D., and colleagues, published online on Dec.

CSH Protocols Features Methods For Studying DNA Repair And Protein Modification
This month's issue of Cold Spring Harbor Protocols (http://www.cshprotocols.org/TOCs/toc1_09.dtl) features two articles detailing experimental methods for the analysis of molecular processes involved in DNA repair and post-translational modification of proteins. Homologous recombination is an important mechanism for the repair of damaged chromosomes.
