Time of day matters to thirsty trees, U of T researcher discovers
The time of day matters to forest trees dealing with drought, according to a new paper produced by a research team led by Professor Malcolm Campbell, University of Toronto Scarborough's vice-principal for research and colleagues in the department of cell and systems biology at the St. George campus. view more (2009-11-24)
Surface bacteria maintain skin's healthy balance
On the skin's surface, bacteria are abundant, diverse and constant, but inflammation is undesirable. Research at the University of California, San Diego School of Medicine now shows that the normal bacteria living on the skin surface trigger a pathway that prevents excessive inflammation after injury. view more (2009-11-23)
New culprit for viral infections among elderly -- an overactive immune response
Researchers at Yale School of Medicine have found that exaggerated responses of the immune system explain why the elderly succumb to viral infections more readily than younger people. view more (2009-11-19)
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)
Can a plant be altruistic?
The concept of altruism has long been debated in philosophical circles, and more recently, evolutionary biologists have joined the debate. view more (2009-11-11)
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)
Hydrogen Peroxide's Link to Living Cells
If a circadian rhythm is like an orchestra - the united expression of the rhythms of millions of cells - a common chemical may serve as the conductor, or at least as the baton. view more (2009-11-04)
Extending treatment after liver transplant may benefit patients with hepatitis C recurrence
Extending hepatitis C treatment for liver transplant patients beyond current practice results in high rates of clearance of the hepatitis C virus from the blood, as well as a low rate of relapse, according to a Henry Ford Hospital study. view more (2009-11-02)
Bacteria 'launch a shield' to resist attack
Researchers from the University of Copenhagen and the Technical University of Denmark along with other collaborators in Denmark and the US found that the bacterium Pseudomonas aeruginosa can 'switch on' production of molecules that kill white blood cells - preventing the bacteria being eliminated by the body's immune system. view more (2009-11-02)
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)
Texas A&M researchers find new mechanism for circadian rhythm
Molecules that may hold the key to new ways to fight cancer and other diseases have been found to play an important role in regulating circadian rhythm, says Liheng Shi, a researcher in Texas A&M's Department of Veterinary Integrative Biosciences. 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)
Protein interaction network can respond Helicobacter pylori infection?
Helicobacter pylori (H pylori) is a gram negative bacterium which infects about 50% of the world population. H pylori colonization causes a strong systemic immune response. 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)
Elderly immune system needs a boost
Elderly cancer patients need a combination of treatments tailor-made to their specific needs to successfully combat the disease. view more (2009-10-09)
LA BioMed study finds higher survival rate among intoxicated trauma patients
Trauma patients who were intoxicated before their injuries were more likely to survive than trauma patients who suffered similar injuries but were sober at the time. view more (2009-10-01)
How would Einstein use e-mail?
You're not as different from Albert Einstein and Charles Darwin after all, at least when it comes to patterns of correspondence. view more (2009-09-28)
Fish fend off invading germs with an initial response similar to the one found in people
Since the human response to infection is highly complex, research to understand how people fight infection is facilitated by studying how similar processes occur in simpler organisms. view more (2009-09-24)
