Grey Matter Loss from Smoking May be Reversible: Study

February 10, 2015 5:12 pm | News | Comments

Damage to the brain's outer layer caused by smoking may be reversible after quitting, but it could take years, a study said. Brain scans of 500 Scottish septuagenarians confirmed a link between smoking and an acceleration of age-related thinning of the cortex—the outer layer of grey matter, researchers reported.

Screening Tool Could Speed Ovarian Cancer Drug Development

February 10, 2015 4:56 pm | by University of Chicago | News | Comments

University of Chicago Medicine researchers have built a model system that uses multiple cell types from patients to rapidly test compounds that could block the early steps in ovarian cancer metastasis. Their three-dimensional cell-culture system, adapted for high-throughput screening, has enabled them to identify small molecules that can inhibit adhesion and invasion, preventing ovarian cancers from spreading to nearby tissues.

Highlighting Brain Cells' Role in Navigating Environment

February 5, 2015 3:13 pm | by Dartmouth University | News | Comments

A new Dartmouth College study sheds light on the brain cells that function in establishing one's location and direction. The findings contribute to our understanding of the neural mechanisms underlying our abilities to successfully navigate our environment, which may be crucial to dealing with brain damage due to trauma or a stroke and the onset of diseases such as Alzheimer's.

Unlocking Fat

February 5, 2015 2:57 pm | by Peter Reuell, Harvard | News | Comments

Have you ever wondered why it’s so tough to put down that last slice of bacon? Part of the answer is that humans are evolutionarily programmed to crave fatty foods, which offer the biggest bang for the buck, nutritionally speaking, with more than twice the calorie density of protein- or starch-rich food.

Tackling Cancer With a New Paradigm

February 5, 2015 2:33 pm | by Yale | News | Comments

In the 1980s, immunotherapy researcher Lieping Chen, M.D., Ph.D., embraced the career goal of curing one cancer. That lofty-seeming goal is beginning to look more modest today. Recent clinical trials have shown that one cancer after another is vulnerable to immune modulation therapy, a cancer-fighting strategy Chen pioneered that for years was considered marginal.

New Source of Cells for Modeling Malaria

February 5, 2015 2:29 pm | by MIT | News | Comments

In 2008, the World Health Organization announced a global effort to eradicate malaria, which kills about 800,000 people every year. As part of that goal, scientists are trying to develop new drugs that target the malaria parasite during the stage when it infects the human liver, which is crucial because some strains of malaria can lie dormant in the liver for several years before flaring up.
