Researchers test sugary solution to Alzheimer's disease Posted: 28 Feb 2012 04:10 PM PST Slowing or preventing the development of Alzheimer's disease, a fatal brain condition expected to hit one in 85 people globally by 2050, may be as simple as ensuring a brain protein's sugar levels are maintained, according to researchers.

Stopping hormone therapy might help breast cancer to regress Posted: 28 Feb 2012 04:09 PM PST As soon as women quit hormone therapy, their rates of new breast cancer decline, supporting the hypothesis that stopping hormones can lead to tumor regression, according to a new report.

Molecular duo dictate human weight and energy levels Posted: 28 Feb 2012 04:09 PM PST Researchers have discovered a key cellular mechanism that may help the brain control how much we eat, what we weigh, and how much energy we have.

Potential solution to melanoma's resistance to vemurafenib Posted: 28 Feb 2012 03:58 PM PST Researchers have found that the XL888 inhibitor can prevent resistance to the chemotherapy drug vemurafenib, commonly used for treating patients with melanoma.

Open your eyes and smell the roses: Activating the visual cortex improves our sense of smell Posted: 28 Feb 2012 03:55 PM PST A new study reveals for the first time that activating the brain's visual cortex with a small amount of electrical stimulation actually improves our sense of smell.

Eat your broccoli: Another mechanism discovered by which sulforaphane prevents cancer Posted: 28 Feb 2012 11:05 AM PST Researchers have discovered yet another reason why the "sulforaphane" compound in broccoli and other cruciferous vegetables is so good for you -- it provides not just one, but two ways to prevent cancer through the complex mechanism of epigenetics.

Cold air chills heart's oxygen supply, making snow shoveling dangerous for some people Posted: 28 Feb 2012 09:39 AM PST People with heart disease may not be able to compensate for their bodies' higher demand for oxygen when inhaling cold air, according to researchers, making snow shoveling and other activities dangerous for some.

Initial genetic analysis reveals Iceman Ötzi predisposed to cardiovascular disease Posted: 28 Feb 2012 09:38 AM PST The famous Iceman mummy known as Ötzi was genetically predisposed to cardiovascular diseases, according to recent studies. Not only was this genetic predisposition demonstrable in the 5,000-year-old ice mummy, there was also already a symptom in the form of arteriosclerosis, or hardening of the arteries.

Newly emerging staph strain transits more easily among humans Posted: 28 Feb 2012 08:43 AM PST Using genome sequencing and household surveillance, scientists have pieced together how a newly emerging type of Staphylococcus aureus bacteria has adapted to transmit more easily among humans. Their new study underscores the need for vigilance in surveillance of S. aureus.

Study compares traits of autism, schizophrenia Posted: 28 Feb 2012 08:43 AM PST A professor is studying the differences between the social impairments found in autism and schizophrenia to help develop better treatments for people with both disorders. Autism spectrum disorder and schizophrenia are distinct disorders with unique characteristics, but they share similarities in social dysfunction.

Stress changes how people make decisions Posted: 28 Feb 2012 08:43 AM PST Trying to make a big decision while you're also preparing for a scary presentation? You might want to hold off on that. Feeling stressed changes how people weigh risk and reward. A new article published in Current Directions in Psychological Science, a journal of the Association for Psychological Science, reviews how, under stress, people pay more attention to the upside of a possible outcome.

Better health another reason for getting a degree Posted: 28 Feb 2012 08:40 AM PST Attaining at least a bachelor's degree after 25 years of age is associated with better midlife health, new research shows.

Eye movement not engaged in 'arms race' Posted: 28 Feb 2012 08:40 AM PST We make our eye movements earlier or later in order to coordinate with movements of our arms, neuroscientists have found. Their study points to a mechanism in the brain that allows for this coordination and may have implications for rehabilitation and prosthetics.

Sperm cannot detect smells: End of 'Lily of the Valley phenomenon' in sperm research? Posted: 28 Feb 2012 07:20 AM PST Scientists have now discovered that sperm do not function like olfactory cells -- a finding that casts doubt on the assumption that scents play a role in fertilization.

How the brain responds to deceptive advertising Posted: 28 Feb 2012 07:20 AM PST Several specific regions of our brains are activated in a two-part process when we are exposed to deceptive advertising, according to new research. The work opens the door to further research that could help us understand how brain injury and aging may affect our susceptibility to fraud or misleading marketing.

How accurate are rapid flu tests? Posted: 27 Feb 2012 05:47 PM PST A new study has put the accuracy of rapid influenza diagnostic tests (RIDTs) under the microscope. The meta-analysis of 159 studies showed three key findings: that RIDTs can be used to confirm the flu, but not to rule it out; that test accuracy is higher in children than it is in adults; and that RIDTs are better at detecting the more common influenza A virus than they are at detecting influenza B.

How immune system's 'first responders' target infection Posted: 27 Feb 2012 01:28 PM PST Researchers have discovered previously unsuspected aspects of the chemokine guidance system used by the body's first line of defense against infection.

Could rosemary scent boost brain performance? Posted: 24 Feb 2012 04:43 PM PST Hailed since ancient times for its medicinal properties, we still have a lot to learn about the effects of rosemary. Now researchers have shown for the first time that blood levels of a rosemary oil component correlate with improved cognitive performance.
