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.

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.

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.
