Reporting in the January 1 issue of Science, neuroscientists at the Johns Hopkins University School of Medicine have discovered that the birth of new cells, which depends on brain activity, also depends on a protein that is involved in changing epigenetic marks in the cell's genetic material. http://www.physorg.com/news150657983.html Medicine & Health Thu, 08 Jan 2009 17:26:23 EST news150657983 New research published in the international journal Neurobiology of Aging by Marc Poulin, PhD, DPhil, finds that being physically fit helps the brain function at the top of its game. An Alberta Heritage Foundation for Medical Research Senior Scholar, Poulin finds that physical activity benefits blood flow in the brain, and, as a result, cognitive abilities. http://www.physorg.com/news150645185.html Medicine & Health Thu, 08 Jan 2009 13:53:05 EST news150645185 When you have 400 earthquakes on top of one of the largest supervolcanoes on Earth, people pay attention. http://www.physorg.com/news150573539.html Space & Earth Wed, 07 Jan 2009 17:58:59 EST news150573539 While some emerging technologies can create environments that require very little physical effort, one Kansas State University researcher thinks games like Nintendo's Wii Fit can help promote physical rather than sedentary activities for people of all ages. http://www.physorg.com/news150485556.html Medicine & Health Tue, 06 Jan 2009 17:32:36 EST news150485556 A recent international study fails to support the common belief that the number of calories burned in physical activity is a key factor in rising rates of obesity. http://www.physorg.com/news150461696.html Medicine & Health Tue, 06 Jan 2009 10:54:56 EST news150461696 Females of all ages are less active than their male peers. Two studies, presented today (Tuesday 6 January) at a major academic conference, reveal the gender difference in activity levels among school children and the over 70s. Both studies show males to be more physically active than females. http://www.physorg.com/news150446607.html Medicine & Health Tue, 06 Jan 2009 06:43:27 EST news150446607 Just seeing someone smoke can trigger smokers to abandon their nascent efforts to kick the habit, according to new research conducted at Duke University Medical Center. http://www.physorg.com/news150397760.html Medicine & Health Mon, 05 Jan 2009 17:09:20 EST news150397760 The Centers for Disease Control and Prevention and the American College of Sports Medicine recommends at least 30 minutes of moderate-intensity physical activity on most days of the week in order to maintain and improve optimal health. This recommendation is especially important for older Americans, who can be less likely to fulfill this requirement, yet are more at risk for chronic diseases associated with aging. http://www.physorg.com/news149768698.html Medicine & Health Mon, 29 Dec 2008 10:24:58 EST news149768698 Dollar signs for eyes - cartoonists have been drawing them for years, and the artists, while whimsical, may have been onto something.

On the other hand, it is difficult to explain why only certain people get better from placebos. A team of researchers from Uppsala University and Gothenburg University have now found gene variants that can impact the placebo effect and a mechanism in the brain that characterizes those who respond to placebos. http://www.physorg.com/news147531408.html Medicine & Health Wed, 03 Dec 2008 12:56:48 EST news147531408 According to a new study, published in the November issue of Diabetes Care, a majority of diabetics avoid physical activity because they worry about exercise-induced hypoglycemia (low blood sugar) and severe consequences including loss of consciousness. Despite the well-known benefits of exercise, this new study builds on previous investigations that found more than 60 percent of adult diabetics aren`t physically active. http://www.physorg.com/news146930655.html Medicine & Health Wed, 26 Nov 2008 14:04:15 EST news146930655 Although there has been an increase in the number of new arthritis treatments in recent years, the best results will come from more effective use of the drugs we have. Research published today in BioMed Central's open access journal Arthritis Research and Therapy investigates the effectiveness of available arthritis drugs and concludes that better management is the most important factor. http://www.physorg.com/news146924105.html Medicine & Health Wed, 26 Nov 2008 12:15:05 EST news146924105 New evidence may explain why it is that we lose not only our youthful looks, but also our youthful pattern of gene activity with age. A report in the November 26th issue of the journal Cell, a Cell Press publication, reveals that a protein perhaps best known for its role in the life-extending benefits of a low-calorie diet also maintains the stability of the mammalian genome -the complete set of genetic instructions "written" in DNA. http://www.physorg.com/news146922348.html Biology Wed, 26 Nov 2008 11:45:48 EST news146922348 Scientists at Penn State have shed light on some of the processes that regulate genes -- such as the processes that ensure that proteins are produced at the correct time, place, and amount in an organism -- and they also have shed light on the evolution of the DNA regions that regulate genes. The team focused on regulatory regions that, when bound to the protein GATA1, are thought to turn on genes that play an important role in the development of red blood cells. "Our findings could help others to develop drugs to treat people who suffer from sickle-cell anemia and other blood disorders," said Ross Hardison, the T. Ming Chu Professor of Biochemistry and Molecular Biology and the team's leader. The results will be published on 1 December 2008 in the journal Genome Research. http://www.physorg.com/news146833211.html Biology Tue, 25 Nov 2008 11:00:11 EST news146833211 Weight and appetite experts from around the world met at a conference in Bangkok earlier this year to discuss sex differences in obesity. One line of discussion looked at factors leading to women's weight gain during menopause, and how it might be avoided. http://www.physorg.com/news146766863.html Medicine & Health Mon, 24 Nov 2008 16:34:23 EST news146766863 Watching plenty of television combined with low self-esteem, poor relationships with parents, and low academic achievement are some of the factors that may add up to young people having sex before the age of 15. Alternatively, a parent's positive influence may go a long way to reduce risky sexual behavior during adolescence, according to Myeshia Price and Dr. Janet Hyde from the University of Wisconsin in the USA. Their findings have just been published online in Springer's Journal of Youth and Adolescence. http://www.physorg.com/news146745891.html Other Sciences Mon, 24 Nov 2008 10:44:51 EST news146745891
