La Jolla, Calif. -- U.S. researchers say they've determined when people eat might be just as vital to their health as what they eat.
Scientists at the Salk Institute for Biological Studies say experiments with mice revealed the daily waxing and waning of genes in the liver is mostly controlled by food intake and not by the body's circadian clock, as conventional wisdom had it.
"If feeding time determines the activity of a large number of genes completely independent of the circadian clock, when you eat and fast each day will have a huge impact on your metabolism," said Assistant Professor Satchidananda Panda, who led the research.
Washington, September 14 -- Whether cell phones are dangerous for our health or not has been a question of debate for scientists. Almost 600 studies have been done so far to determine the effects of cell phones on the health, but every time contradictory results have come up.
London, April 29: Low and middle-income countries are less prepared than developed nations to fight an outbreak of swine flu, health experts say.
"Of particular concern is the ability of low-income and middle-income countries to detect and mitigate the effects of this new virus on their populations," said The Lancet, an authoritative medical journal.
"History has shown that developing countries are disproportionately affected by an influenza pandemic," it said in an editorial published Tuesday.
An "Electronic Mosquito" could replace invasive methods of drawing blood samples from diabetics to check glucose levels.
The common method of drawing blood from fingertips and using glucose testing strips and metres can be painful, inconvenient and time-consuming.
Now, electrical engineers at the Schulich School of Engineering at the University of Calgary have patented a device called the Electronic Mosquito or e-Mosquito, a patch approximately the size of a deck of cards which contains four micro-needles that "bite" sequentially at programmed intervals.
A third of teens who smoke cannabis regularly use it as medication, rather than as a means of getting high, claims a new study.
Joan Bottorff worked with researchers from the University of British Columbia, funded by the Canadian Institutes of Health Research, to conduct in-depth interviews with 63 cannabis-using adolescents.
Of these, 20 claimed that they used cannabis to relieve or manage health problems. Bottorff said: "Marijuana is perceived by some teens to be the only available alternative for those experiencing difficult health problems when legitimate medical treatments have failed or when they lack access to appropriate health care."
London, March 18: Adding more to the detrimental effects of obesity, a latest study of nearly a million people shows it can shorten life expectancy by almost a decade. Being slightly overweight too can pour perils – it may take as much as three years off your life, researchers warn.
