Brain traffic jams that can disappear in 30 seconds

Posted: 06 Jun 2014 03:48 PM PDT

Motorists in Los Angeles, San Francisco and other gridlocked cities could learn something from the fruit fly. Scientists have found that cellular blockages, the molecular equivalent to traffic jams, in nerve cells of the insect's brain can form and dissolve in 30 seconds or less.

Research could lead to new cancer assay, aid both dogs and humans

Posted: 05 Jun 2014 12:57 PM PDT

Veterinary researchers have identified a unique group of proteins that indicate the presence of transitional cell carcinoma -- the most common cause of bladder cancer -- and may lead to a new assay which could better diagnose this disease in both dogs and humans. Bladder cancer is particularly common in some dog breeds, such as collies, sheepdogs and terriers, but is rarely diagnosed in animals before it has spread significantly. Some assays exist to detect it in humans, but they often have a high-number of false-positive identifications.

Unmasking viral invaders with mass spectrometry

Posted: 05 Jun 2014 11:17 AM PDT

Using a technological platform commonly used in physics and chemistry called mass spectrometry, researchers describe the dynamics of a viral infection over a three-day course, discovering ways the pathogen evades the immune system and how certain viral proteins target and destroy human proteins that defend against infection.
