Study finds the air rich with bacteria

...t of F. tularensis detected in an air sample is in synch with normal levels, or if it's suspicious. "Almost all of the bacterial bioterror pathogens are in the environment and in the air naturally, so we need to find their natural backgrounds," says Andersen. An airborne bacterial census will also ...

RNA found in the cellular centrosome of surf clams

...ter fertilization, and, once fertilized, divide in synch every 30-50 minutes -- providing billions of biochemically identical cells to study. Using a purification technique Palazzo developed at the MBL, the scientists were able to isolate relatively large quantities of clam centrosomes for their research...

Animal models show that anabolic steroids flip the adolescent brain's switch for aggression

...ence, also showed that aggression rose and fell in synch with neurotransmitter levels in the brain's aggression control region. Behavioral Neuroscience is published by the American Psychological Association (APA). Neuroscientists are deeply concerned about rising adolescent abuse of anabolic-androgenic ...

A resetting signal keeps circadian rhythm on track in Drosophila fruit flies

...morning and evening activity and are maintained in synch even when the flies are plunged into darkness for extended periods of time. This daily resetting signal flows from the morning to the evening cells and maintains a 12-hour difference between the timing of morning and evening activity, without the n...

Past droughts geographically widespread in the West, according to tree-ring data

...Upper Colorado and the Salt/Verde, were so much in synch during periods of extremely high or extremely low flow." She added, "The recent joint drought, while severe, is not unprecedented when compared to those in the previous five centuries." The findings of the first phase are being shared with represent...

Discovery clarifies role of peptide in biological clock

...their beat while others were cycling but unable to synch to each other. But when Herzog and Aton added VIP to the mice cells, the synchronicity was restored, showing that VIP couples pacemaker cells and drives rhythms in slave cells. "VIP between SCN neurons is like a rubber band between the pendulums of...
