Scientists produce world's first magnetic soap Posted: 23 Jan 2012 02:48 PM PST Scientists have developed a soap, composed of iron rich salts dissolved in water, that responds to a magnetic field when placed in solution. The soap's magnetic properties were shown to result from tiny iron-rich clumps that sit within the watery solution. The generation of this property in a fully functional soap could calm concerns over the use of soaps in oil-spill clean ups and revolutionize industrial cleaning products.

Researchers develop gene therapy that could correct a common form of blindness Posted: 23 Jan 2012 01:34 PM PST A new gene therapy has the potential to treat a common form of blindness that strikes both youngsters and adults. The technique works by replacing a malfunctioning gene in the eye with a normal working copy that supplies a protein necessary for light-sensitive cells in the eye to function. Several complex steps remain before the gene therapy technique can be used in humans, but once at that stage, it has great potential to change lives.

Major study of ocean acidification helps scientists evaluate effects of atmospheric carbon dioxide on marine life Posted: 23 Jan 2012 01:33 PM PST Might a penguin's next meal be affected by the exhaust from your tailpipe? The answer may be yes, when you add your exhaust fumes to the total amount of carbon dioxide lofted into the atmosphere by humans since the industrial revolution. One-third of that carbon dioxide is absorbed by the world's oceans, making them more acidic and affecting marine life.

Use of iodinated contrast media in imaging procedures appears to affect thyroid function Posted: 23 Jan 2012 01:33 PM PST Exposure to iodinated contrast media during imaging procedures is associated with changes in thyroid function, and increased risk of developing hyperthyroidism, according to a new report.

Lifelong brain-stimulating habits linked to lower Alzheimer's protein levels Posted: 23 Jan 2012 01:33 PM PST People who have made mental engagement a lifelong habit have lower levels of a key protein linked to Alzheimer's disease, according to a new study by neuroscientists. The findings could provide support for cognitive therapies to help prevent the onset of a debilitating disease.

Waiting for Death Valley's big bang: Volcanic explosion crater may have future potential Posted: 23 Jan 2012 12:25 PM PST In California's Death Valley, death is looking just a bit closer. Geologists have determined that the half-mile-wide Ubehebe Crater, formed by a prehistoric volcanic explosion, was created far more recently than previously thought -- and that conditions for a sequel may exist today.

How cells dispose of their waste: Researchers reveal the structure of the cellular protein degradation machinery Posted: 23 Jan 2012 12:20 PM PST Defective proteins that are not disposed of by the body can cause diseases such as Alzheimer's or Parkinson's. Scientists recently succeeded in revealing the structure of the cellular protein degradation machinery (26S proteasome) by combining different methods of structural biology. The results represent an important step forward in the investigation of the 26S proteasome.

Magic mushrooms' effects illuminated in brain imaging studies Posted: 23 Jan 2012 12:20 PM PST Brain scans of people under the influence of the psilocybin, the active ingredient in magic mushrooms, have given scientists the most detailed picture to date of how psychedelic drugs work. The findings of two new studies identify areas of the brain where activity is suppressed by psilocybin and suggest that it helps people to experience memories more vividly.

Strongest solar radiation storm since 2005 Posted: 23 Jan 2012 10:11 AM PST NOAA's Space Weather Prediction Center -- the nation's official source of warnings and alerts about space weather and its impacts on Earth -- has issued a watch for a geomagnetic storm associated with a bright flare on the sun Sunday evening (Jan. 22, 2012). The storm could arrive Tuesday morning, with possible impacts to navigation, the power grid and satellites.

Nurturing mothers rear physically healthier adults Posted: 23 Jan 2012 09:39 AM PST Nurturing mothers have garnered accolades for rescuing skinned knees on the playground and coaxing their children to sleep with lullabies. Now they're gaining merit for their offspring's physical health in middle age. While children raised in families with low socioeconomic status frequently go on to have high rates of chronic illness in adulthood, a sizable minority remain healthy across the life course, new research shows.

Ultrafast magnetic processes observed 'live' using an X-ray laser Posted: 23 Jan 2012 09:33 AM PST In first-of-their-kind experiments, scientists have been able to precisely follow how the magnetic structure of a material changes. The study was carried out on cupric oxide (CuO). The change of structure was initiated by a laser pulse, and then, with the help of short X-ray pulses, near-instantaneous images were obtained at different points in time for individual intermediate steps during the process.

Graphene 'invisible' to water: How the extreme thinness of graphene enables near-perfect wetting transparency Posted: 23 Jan 2012 09:31 AM PST Graphene is the thinnest material known to science. The nanomaterial is so thin, in fact, water often doesn't even know it's there. Engineering researchers coated pieces of gold, copper, and silicon with a single layer of graphene, and then placed a drop of water on the coated surfaces. Surprisingly, the layer of graphene proved to have virtually no impact on the manner in which water spreads on the surfaces.

Compounds in mate tea induce death in colon cancer cells, in vitro study shows Posted: 23 Jan 2012 08:55 AM PST In a recent study, scientists showed that human colon cancer cells die when they are exposed to the approximate number of bioactive compounds present in one cup of mate tea, which has long been consumed in South America for its medicinal properties.

Patterns of antibiotic-resistant bacteria found in Galapagos reptiles Posted: 23 Jan 2012 08:55 AM PST Land and marine iguanas and giant tortoises living close to human settlements or tourist sites in the Galapagos islands were more likely to harbor antibiotic-resistant bacteria than those living in more remote or protected sites on the islands, researchers report. Many of the reptiles harbor E. coli bacteria that are resistant to ampicillin, doxycycline, tetracycline, and trimethoprin/sulfamethoxazole.

Easier testing for diabetics? Biochip measures glucose in saliva, not blood Posted: 23 Jan 2012 08:55 AM PST Engineers have designed a biological device that can measure glucose concentrations in human saliva. The technique could eliminate the need for diabetics to draw blood to check their glucose levels. The biochip uses plasmonic interferometers and could be used to measure a range of biological and environmental substances.

Patterns of chromosome abnormality: The key to cancer? Posted: 23 Jan 2012 08:55 AM PST Researchers have combined techniques from computer science and statistics to discover that many chromosomal pairs are lost or gained together across various cancer types, such as kidney, skeleton, and liver cancers. Tracking these changes, he says, could aid our understanding of the driving forces of cancer's progress.

Women report feeling pain more intensely than men, says study of electronic medical records Posted: 23 Jan 2012 08:55 AM PST Women report more intense pain than men in virtually every disease category, according to researchers who mined a huge collection of electronic medical records to establish the broad gender difference to a high level of statistical significance.

Molecular fingerprint discovered that may improve outcomes for head and neck cancer patients Posted: 23 Jan 2012 08:42 AM PST Researchers have found a biomarker in head and neck cancers that can predict whether a patient's tumor will be life threatening. The biomarker is considered particularly promising because it can detect the level of risk immediately following diagnosis.

Bonobos' unusual success story Posted: 23 Jan 2012 07:18 AM PST Bonobos are among the closest living relatives of humans. Like other great apes they live in groups made up of several males and females. Unlike other ape species however, male bonobos do not, in general, outrank female individuals and do not dominate them in mating contexts. Scientists have now found that in wild bonobos high-ranking males were more aggressive and their mating success was higher when compared to lower-ranking males.

Lessons in coral reef survival from deep time Posted: 23 Jan 2012 06:48 AM PST Lessons from tens of millions of years ago are pointing to new ways to save and protect today's coral reefs and their myriad of beautiful and many-hued fishes at a time of huge change in the Earth's systems. Today's complex relationship between fishes and corals developed relatively recently in geological terms -- and is a major factor in shielding reef species from extinction, say experts.

Saving the snow leopard with stem cells Posted: 23 Jan 2012 06:47 AM PST The survival of the endangered snow leopard is looking promising thanks to scientists who have, for the first time, produced embryonic stem-like cells from the tissue of an adult leopard.

Genes and timing of menopause Posted: 23 Jan 2012 06:47 AM PST Researchers have discovered 13 new regions of the genome associated with the timing of menopause.
