Hebrew University, US scientists find clue to mystery of biological clock
How does our biological system know that it is supposed to operate on a 24-hour cycle? Scientists at the Hebrew University of Jerusalem have discovered that a tiny molecule holds the clue to the mystery. view more (2009-11-30)
Just like old times: Generating RNA molecules in water
A key question in the origin of biological molecules like RNA and DNA is how they first came together billions of years ago from simple precursors. view more (2009-11-23)
Rice ties in race for atomic-scale breakthrough
Everybody loves a race to the wire, even when the result is a tie. The great irony is the ultraprecise clocks that could result from this competition could probably break any tie. view more (2009-11-18)
New paper describes connections between Circadian and metabolic systems
A paper by University of Notre Dame biologist Giles Duffield and a team of researchers offers new insights into a gene that plays a key role in modulating the body's Circadian system and may also simultaneously modulate its metabolic system. view more (2009-11-13)
Faulty body clock may make kids bipolar
Malfunctioning circadian clock genes may be responsible for bipolar disorder in children. Researchers writing in the open access journal BMC Psychiatry found four versions of the regulatory gene RORB that were associated with pediatric bipolar disorder. view more (2009-11-12)
The bizarre lives of bone-eating worms
The females of the recently discovered Osedax marine worms feast on submerged bones via a complex relationship with symbiotic bacteria, and they are turning out to be far more diverse and widespread than scientists expected. view more (2009-11-10)
Java and nighttime jobs don't mix: study
Night-shift workers should avoid drinking coffee if they wish to improve their sleep, according to research published in the journal Sleep Medicine. view more (2009-11-04)
Circadian surprise: A heat sensor for body-clock synchronization
New research on the fruit-fly brain points to a possible mechanism by which temperature influences the body clock, according to scientists from Queen Mary, University of London. view more (2009-10-30)
Getting on 'the GABA receptor shuttle' to treat anxiety disorders
There are increasingly precise molecular insights into ways that stress exposure leads to fear and through which fear extinction resolves these fear states. view more (2009-10-22)
Accelerated bone growth may be an indicator of hypertension in children
Children whose bones are "older" than their chronological age may be at an increased risk of hypertension, according to a study reported today (19 October) in Hypertension: Journal of the American Heart Association. view more (2009-10-21)
The food-energy cellular connection revealed
Our body's activity levels fall and rise to the beat of our internal drums-the 24-hour cycles that govern fundamental physiological functions, from sleeping and feeding patterns to the energy available to our cells. view more (2009-10-16)
Scientists reveal new pattern in our daily clock
The findings of a study published in Science today turn a long-held theory on circadian rhythms on its head and mean that we may now be able to develop new drugs and approaches to tune the daily clock to treat sleep disorders and to aid recovery from long-distance flights. view more (2009-10-09)
U-M discovery about biological clocks overturns long-held theory
University of Michigan mathematicians and their British colleagues say they have identified the signal that the brain sends to the rest of the body to control biological rhythms, a finding that overturns a long-held theory about our internal clock. view more (2009-10-09)
Developing enzymes to clean up pollution by explosives
Scientists at the University of York have uncovered the structure of an unusual enzyme which can be used to reverse the contamination of land by explosives. view more (2009-10-09)
Racing against the clock to distribute H1N1 flu vaccine
Drug companies are sprinting ahead in a race against the clock to deliver millions of doses of vaccine for the H1N1 influenza virus before cooler weather ushers in the 2009-2010 flu season. view more (2009-10-01)
New discovery reveals fate of nanoparticles in human cells
Scientists funded by the Biotechnology and Biological Sciences Research Council (BBSRC) have uncovered what happens to biomimetic nanoparticles when they enter human cells. view more (2009-09-23)
Scientists discover key factor in regulating placenta and fetal growth
Scientists funded by the Biotechnology and Biological Sciences Research Council (BBSRC) have shown that a common biological protein molecule called SHP-2 is crucial for encouraging placenta growth. view more (2009-09-21)
WUSTL research finds individual cells isolated from the biological clock can keep daily time, but are unreliable
Alexis Webb enters a small room at Washington University in St. Louis with walls, floor and ceiling painted dark green, shuts the door, turns off the lights and bends over a microscope in a black box draped with black cloth. Through the microscope, she can see a single nerve cell on a glass cover slip glowing dimly. view more (2009-09-10)
Electrical circuit runs entirely off power in trees
You've heard about flower power. What about tree power? It turns out that it's there, in small but measurable quantities. There's enough power in trees for University of Washington researchers to run an electronic circuit. view more (2009-09-09)
Optical atomic clock becomes portable
You imagine a clock to be different - yet the optical table with its many complicated set-ups really is one. Optical clocks like the strontium clock in the Physikalisch-Technische Bundesanstalt (PTB) in Braunschweig could be the atomic clocks of the future; some of them though are already ten times more precise and stable than the best primary... view more...
