A new study suggests that diabetes patients with neuropathy should control lipid counts as rigorously as they do glucose levels.

Is Organic Overrated? Posted: 23 May 2009 02:00 PM PDT Just a few short years ago, if you wanted to buy organic food, you had to make a special trip to an out-of-the-way grocery store. Today, organic products are, well, cropping up all over the place. Are they really worth the higher price or is it just another marketing maneuver?

Money Worries Make Women Spend More Posted: 23 May 2009 02:00 PM PDT At times of crisis women are more inclined to spend themselves out of misery than at stable times, a new survey suggests. Psychologists say that the recession could force more women to overspend or increase their risk of mental illness.

Alzheimer's Discovery Could Bring Early Diagnosis, Treatment Closer Posted: 23 May 2009 08:00 AM PDT A discovery offers new hope for the early diagnosis and treatment of Alzheimer's disease. Scientists report that the addition of a single phosphate to an amino acid in a key brain protein is a principal cause of Alzheimer's.

New Contraceptive Device Is Designed To Prevent Sexual Transmission Of HIV Posted: 23 May 2009 08:00 AM PDT Researchers have published results showing that a new contraceptive device may also effectively block the transmission of the HIV virus.

Surprising Twist To Photosynthesis: Scientists Swap Key Metal Necessary For Turning Sunlight Into Chemical Energy Posted: 23 May 2009 02:00 AM PDT Photosynthesis is a remarkable biological process that supports life on earth. Plants and photosynthetic microbes do so by harvesting light to produce their food, and in the process, also provide vital oxygen for animals and people. Now, a large, international collaboration has come up with a surprising twist to photosynthesis by swapping a key metal necessary for turning sunlight into chemical energy.

Molecular Link Between Sleep And Weight Gain Posted: 23 May 2009 02:00 AM PDT There appears to be a link between sleep and weight control, with some studies indicating that sleep disruption can increase weight gain and other studies that diet affects sleep. New research now provides molecular evidence to support this association. It is shown that T-type calcium channels regulate body weight maintenance and sleep in mice, suggesting that sleep and circadian treatment approaches may be of benefit in the fight against obesity.

Helpful Fish: Cooperative Cichlids Boost Their Own Reproductive Success Posted: 23 May 2009 02:00 AM PDT Subordinate individuals living within a group of vertebrates sometimes assist a more dominant pair by helping to raise the dominant pair's offspring -- this has been shown to occur among subordinate female cichlids. Scientists suggest that rather than engaging in an act of reciprocal altruism, these subordinate females actually benefit from the care-giving they offer as the more helpful subordinates are more likely to reproduce.

Efficacy Of CT Scans For Chest Pain Diagnosis Validated Posted: 23 May 2009 02:00 AM PDT The first long-term study following a large number of chest pain patients who are screened with coronary computerized tomographic angiography confirms that the test is a safe, effective way to rule out serious cardiovascular disease in patients who come to hospital emergency rooms with chest pain, according to new research.

University of Alberta researcher Donna Wilson is hoping this can change and already has seen some drastic changes in where Canadians are choosing to die.

Heat-tolerant Coral Reefs Discovered: May Survive Global Warming Posted: 22 May 2009 05:00 PM PDT Experts say that more than half of the world's coral reefs could disappear in the next 50 years, in large part because of higher ocean temperatures caused by climate change. But now scientists have found evidence that some coral reefs are adapting and may actually survive global warming.

Gene Therapy Could Expand Stem Cells' Promise Posted: 22 May 2009 05:00 PM PDT Once placed into a patient's body, stem cells intended to treat or cure a disease could end up wreaking havoc simply because they are no longer under the control of the clinician. But gene therapy has the potential to solve this problem, according to a perspective article.

Popular Television Shows Inaccurately Portray Violent Crime, Researchers Find Posted: 22 May 2009 05:00 PM PDT Researchers compared two popular television shows, CSI and CSI: Miami, to actual US homicide data, and discovered clear differences between media portrayals of violent deaths versus actual murders. This study complements previous research regarding media influences on public health perception.

Unusually Large Family Of Green Fluorescent Proteins Discovered In Marine Creature Posted: 22 May 2009 02:00 PM PDT Scientists have discovered a family of green fluorescent proteins (GFPs) in a primitive sea animal, along with new clues about the role of the proteins that has nothing to do with their famous glow. They have found an unexpected role for proteins: antioxidants.

Adult Stem Cells From Bone Marrow Made To Kill Metastatic Lung Cancer Cells In Mice Posted: 22 May 2009 02:00 PM PDT Researchers have demonstrated the ability of adult stem cells from bone marrow (mesenchymal stem cells, or MSCs) to deliver a cancer-killing protein to tumors. The genetically engineered stem cells are able to home to the cancer cells, both in culture and in mouse models, and deliver TNF-related apoptosis-inducing ligand, destroying the tumor cells while sparing normal cells.

Cell Phone Viruses Pose Serious Threat, Scientists Warn Posted: 22 May 2009 02:00 PM PDT If you own a computer, chances are you have experienced the aftermath of a nasty virus at some point. In contrast, there have been no major outbreaks of mobile phone viral infection, despite the fact that over 80 percent of Americans now use these devices.
