Now Playing newExplosive Evolution Need Not Follow Mass Extinctions
Fossil record of graptoloids challenges the theory that immediately after a mass extinction, species develop new physical traits at a rapid pace. – University of Chicago|2/13/2012 3:00 PM EST
Neuron Memory Key to Taming Chronic PainA team of researchers led by McGill neuroscientist Terence Coderre, who is also affiliated with the Research Institute of the McGill University Health Centre, has found the key to understanding how memories of pain are stored in the brain. More importantly, the researchers are also able to suggest how these memories can be erased, making it possible to ease chronic pain. – McGill University|2/13/2012 2:00 PM EST
Lovelorn Liars Leave Linguistic LeadsOnline daters intent on fudging their personal information have a big advantage: most people are terrible at identifying a liar. But new research is turning the tables on deceivers using their own words. – University of Wisconsin-Madison|2/13/2012 2:00 PM EST
Study: Mexican-American youth add pounds as they lose native eating habitsUniversity of South Carolina have found that Mexican-American youth gain pounds as they move away from the dietary habits of their native country, a move that is putting them at risk for serious health problems. – University of South Carolina|2/13/2012 2:00 PM EST
Scientists deploy lasers, GPS technology to improve snow measurements

Love, Chocolate Good for the Heart, Says Vanderbilt CardiologistBeing involved in a healthy, loving relationship is good for the heart, says Vanderbilt Heart and Vascular Institute cardiologist Julie Damp, M.D. “There are a couple of different theories behind why that might be,” Damp said. People who are married or who are in close, healthy relationships tend to be less likely to smoke, are more physically active and are more likely to have a well-developed social structure, she said. They are also more likely to have lower levels of stress and anxiety in their day-to-day lives. – Vanderbilt University Medical Center|2/13/2012 1:00 PM EST
NYU Study: Blood from Periodontal Disease Can be Used to Screen for DiabetesOral blood samples drawn from deep pockets of periodontal inflammation can be used to measure hemoglobin A1c, an important gauge of a patient’s diabetes status, an NYU nursing-dental research team has found. Hemoglobin A1c blood glucose measures from oral blood compare well to those from finger-stick blood, the researchers say. – New York University|2/13/2012 1:00 PM EST
Newly Identified Fusion Genes in Lung and Colorectal Cancer May Guide Treatment with “Targeted” DrugsNovel gene abnormalities discovered in a subpopulation of lung and colorectal tumors could potentially identify patients with a good chance of responding to highly specific “targeted” drugs already in use for treating other cancers, scientists report. The genetic alterations – pieces of two genes fused together - showed up in a massive search of the DNA in stored tumor samples of non-small cell lung cancer and colorectal cancer, said researchers from Dana-Farber Cancer Institute and Foundation Medicine, Inc. These specific genetic abnormalities had not been previously linked to the two cancer types. – Dana-Farber Cancer Institute|2/13/2012 1:00 PM EST
