Clay key to high-temperature supercapacitors Posted: 03 Sep 2013 04:42 PM PDT Clay, an abundant and cheap natural material, is a key ingredient in a supercapacitor that can operate at very high temperatures, according to researchers who have developed such a device.

Proteins in histone group might influence cancer development, study shows Posted: 03 Sep 2013 04:42 PM PDT Spool-like proteins called histones play a crucial role in packaging the nearly seven feet of DNA found in most human cells. It has been thought that a particular group of histone isoforms were functionally identical. This study shows that these isoforms can have distinct functions, and that they might play a role in cancer development. The results provide a new mechanism for the regulation of chromatin structure.

A surprising low-tech tool of Scotch Magic tape ended up being one of the keys to the discovery.

Scientists encounter holes in tree of life, push for better data storage Posted: 03 Sep 2013 04:41 PM PDT When it comes to public access, the tree of life has holes. A new study shows about 70 percent of published genetic sequence comparisons are not publicly accessible, leaving researchers worldwide unable to get to critical data they may need to tackle a host a problems ranging from climate change to disease control.

Why parenting can never have a rule book: Children's genetics significantly affect how they are parented Posted: 03 Sep 2013 04:41 PM PDT Any parent will tell you that there is no simple recipe for raising a child. Being a parent means getting hefty doses of advice -- often unsolicited -- from others. But such advice often fails to consider a critical factor: The child. A new review of dozens of studies involving more than 14,600 pairs of twins shows that children's genetics significantly affect how they are parented.

Twitter and privacy: One-in-five tweets divulge user location Posted: 03 Sep 2013 04:41 PM PDT Hashtag #doyouknowwhoswatchingyou? A new study sampled more than 15 million tweets, showing that even Twitter users who have opted-out of location tagging may be inadvertently revealing where they are through updates on the social media channel.

Brain wiring quiets the voice inside your head Posted: 03 Sep 2013 04:40 PM PDT Researchers have developed the first diagram of the brain circuitry that enables a complex interplay between the motor system and the auditory system to occur. The research could lend insight into schizophrenia and mood disorders that arise when this circuitry goes awry and individuals hear voices other people do not hear.

Promiscuity and sperm selection improves genetic quality in birds Posted: 03 Sep 2013 04:39 PM PDT Research shows that females can maximize the genetic quality of their offspring by being promiscuous. Researchers studied red junglefowl and found that mating with different males helps females produce healthier offspring -- due to a mechanism in their reproductive tract which favors sperm from the most genetically different males. This is important for animal breeders because it shows that allowing multiple matings produces the most disease resistant and genetically healthy offspring.

The findings could one day lead scientists to new insights about sleep's role in brain repair and growth.

Stressful life events significantly raise the risk of falls in older men Posted: 03 Sep 2013 04:38 PM PDT A study of around 5,000 older men has shown that stressful life events such as death of a loved one, or serious financial problems, significantly raised the risk of falls in the year following the incident.

Uncontrolled hypertension is common, but untreated, worldwide Posted: 03 Sep 2013 04:36 PM PDT A global study has found that many patients don't know they have hypertension and, even if they do, too few are receiving adequate drug therapy for their hypertension.

Massive storm pulls water and ammonia ices from Saturn's depths Posted: 03 Sep 2013 04:36 PM PDT Once every 30 years or so, or roughly one Saturnian year, a monster storm rips across the northern hemisphere of the ringed planet. In 2010, the most recent and only the sixth giant storm on Saturn observed by humans began stirring. It quickly grew to superstorm proportions, reaching 15,000 kilometers (more than 9,300 miles) in width and visible to amateur astronomers on Earth as a great white spot dancing across the surface of the planet.

Disrupted heartbeat restored with regenerative intervention Posted: 03 Sep 2013 12:18 PM PDT Researchers have found a way to resynchronize cardiac motion following a heart attack using stem cells. Scientists implanted engineered stem cells, also known as induced pluripotent stem cells, into damaged regions of mouse hearts following a heart attack.

Iranian telegraph operator, first to propose earthquake early warning system Posted: 03 Sep 2013 12:18 PM PDT In 1909, an Iranian telegraph operator living in the remote desert town of Kerman noticed an unusual movement of the magnetic needle of his telegraph instrument. While other telegraph operators during the late 1800s and early 1900s noticed the phenomenon, the Iranian telegraph operator proposed an earthquake early warning system.

The 'weakest link' in the aging proteome Posted: 03 Sep 2013 12:18 PM PDT Proteins are the chief actors in cells, carrying out the duties specified by information encoded in our genes. Most proteins live only two days or less, ensuring that those damaged by inevitable chemical modifications are replaced with new functional copies.

Birds choose sweet-smelling mates Posted: 03 Sep 2013 09:36 AM PDT For most animals, scent is the instant messenger of choice for quickly exchanging personal profiles. Scientists, however, have long dismissed birds as odor-eschewing Luddites that don't take advantage of scent-based communications. Scientists have now demonstrated that birds do indeed communicate via scents, and that odor reliably predicts their reproductive success.

A new study demonstrates just how cancer-resistant Spalax are, and suggests that the adaptations that help these rodents survive in low-oxygen environments also play a role in their longevity and cancer resistance.

Facebook use by organizations during crises helps public image Posted: 03 Sep 2013 09:35 AM PDT Researchers have found that posting public relations information on Facebook during a time of crisis can improve the overall image of the organization that is experiencing the crisis.

An easier way to control genes Posted: 03 Sep 2013 09:35 AM PDT Researchers have shown that they can turn genes on or off inside yeast and human cells by controlling when DNA is copied into messenger RNA -- an advance that could allow scientists to better understand the function of those genes.

But rather than imposing an exercise regimen to rebuild the worm's body-wall muscles, researchers can bring the wriggle back by stimulating the animal's neurons. And, they say, pharmaceuticals might have a similar effect in mammals.

Aging really is 'in your head:' Scientists answer hotly debated questions about how calorie restriction delays aging process Posted: 03 Sep 2013 09:30 AM PDT Among scientists, the role of proteins called sirtuins in enhancing longevity has been hotly debated, driven by contradictory results from many different scientists.
