A Japanese research group has successfully generated a novel kinase-dead mutant mouse of the CaMKIIalpha gene that completely and exclusively lacks its kinase activity. They examined hippocampal synaptic plasticity and behavioral learning of the mouse, and found a severe deficit.

Antibiotic-resistant bacteria are spreading to and throughout the environment. The resistance pattern for antibiotics in gulls is the same as in humans, and a new study shows that nearly half of Mediterranean gulls in southern France have some form of resistance to antibiotics.

Scientists have completed the first description of the mechanics of so-called nuclear herpes virus capsids.
Tremendous growth in the development of nanomaterials with enhanced performance characteristics which are being used for commercial and medical applications prompts researchers to take a proactive role in examining the nano-bio interface to identify potential risks of engineered nanomaterials and explore methods for safer designs for use in drug delivery therapeutics and commercial products.
Recent public health studies on the US mass transit system have identified several sources of environmental hazards associated with mass transit, including excessive noise. Scientists have found that MTA subways had the highest average noise levels of all mass transit in New York City, with levels high enough to potentially increase the risk of noise [...]
Herschel opened its ‘eyes’ on 14 June and the Photoconductor Array Camera and Spectrometer obtained images of M51, ‘the whirlpool galaxy’ for a first test observation. Scientists obtained images in three colors from the observation, which clearly demonstrate the excellence of Herschel, the largest infrared space telescope ever flown.

A new study suggests that vaccination with 1918 H1N1 influenza virus-like particles not only protected mice and ferrets against the lethal 1918 influenza virus, but also displayed cross-reactive immunity against the potentially pandemic H5N1 influenza virus.
A new NIST assay using a “glow or no glow” technique may soon help the US Department of Homeland Security defend the nation against a spectrum of biological weapons that could be used in a terrorist attack.

The U.S. Food and Drug Administration has advised consumers to stop using three products marketed over-the-counter as cold remedies because they are associated with the loss of sense of smell (anosmia). Anosmia may be long-lasting or permanent.
