A resetting signal keeps circadian rhythm on track in Drosophila fruit flies
A Brandeis University study published this week in Nature shows for the first time that a molecular signal maintains coherence among brain clock cells that regulate daily activity of Drosophila melanogaster (fruit flies). The two key groups of neurons control morning and evening activity and are maintained in synch even when the flies are plunged into darkness for extended periods of time. <...Travelers can avoid jet lag by resetting their body clocks
A simple, at-home treatment -- a single light box and the over-the-counter drug melatonin -- allows travelers to avoid jet lag by resetting their circadian body clock before crossing several time zones, according to new research being published in The Endocrine Society's Journal of Clinical Endocrinology and Metabolism. This treatment can also help those with delayed sleep phase syndrome (DSPS),...Setting the standard for computer models of life
Biologists are making a concerted effort to catalogue all the molecular components of living things, from the smallest molecules and ions to the genetic code. These 'parts lists' help them to build computer models that simulate living processes. By combining models of simple processes they hope to understand and faithfully represent how entire biological systems - be they cells, organs, o...Setting up the laboratory to avoid contamination
The ability of the Polymerase Chain Reaction to amplify a single molecule means that trace amounts of DNA contaminants could serve as templates, resulting in amplification of the wrong template (false positives). Consider the points mentioned below to avoid PCR c...Reduce Errors and Save Time When Setting Up PCRs
Polymerase chain reaction (PCR) setup typically requiresthawing of the various reagents, setting up a master mix,then distributing the mix to the individual reaction tubes. The various handling steps can cause pipetting mistakes and experimental erro...Determining the Signal-to-Noise Ratio and Optimal Photomultiplier gain setting in the GenePix 4000B

Medical tests have become a household name as a guide or reference for remedial treatment measures. Is there a standard that gauges the accuracy level of these medical tests. // Researchers use a Gold standard, a bench mark test against which is compared the medical test in question, to gauge the preciseness of the result or measure the deviation. Generally Gold standard benchmark tests...Braces Work Wonders In Setting Crooked Teeth Right
