Child neurologist finds potential route to better treatments for Fragile X, autism Posted: 23 Oct 2013 01:52 PM PDT Researchers describe a major reason why current medications only moderately alleviate Fragile X symptoms. His team discovered that three specific drugs affect three different kinds of neurotransmitter receptors that all seem to play roles in Fragile X. As a result, current Fragile X drugs have limited benefit because most of them only affect one receptor.

Team uses forest waste to develop cheaper, greener supercapacitors Posted: 23 Oct 2013 01:52 PM PDT Researchers report that wood-biochar supercapacitors can produce as much power as today's activated-carbon supercapacitors at a fraction of the cost -- and with environmentally friendly byproducts.

Coral itself may play important role in regulating local climate: Coral chemicals protect against warming oceans Posted: 23 Oct 2013 01:52 PM PDT Australian marine scientists have found the first evidence that coral itself may play an important role in regulating local climate. They have discovered that the coral animal -- not just its algal symbiont -- makes an important sulfur-based molecule with properties to assist it in many ways, ranging from cellular protection in times of heat stress to local climate cooling by encouraging clouds to form.

Lower blood sugars may be good for the brain Posted: 23 Oct 2013 01:50 PM PDT Even for people who don't have diabetes or high blood sugar, those with higher blood sugar levels are more likely to have memory problems, according to a new study.

Students text, a lot, during class Posted: 23 Oct 2013 12:16 PM PDT The typical student plays with smartphones, laptops, tablets and other digital devices an average of 11 times a day in class. More than 80 percent say their digital habits interfere with learning.

The math says Red Sox have a big edge in the World Series Posted: 23 Oct 2013 11:46 AM PDT Now that the World Series is about to begin, a math professor has announced the probability of each of the contenders winning the best 4 out of 7 game contest. "The Boston Red Sox have a nearly 70 percent chance of winning the series", he says. But he gives the caveat that the St. Louis Cardinals have defeated both the competition and his mathematical model in each of their previous series.

Early-life exposure of frogs to herbicide increases mortality from fungal disease Posted: 23 Oct 2013 11:46 AM PDT A new study shows the herbicide atrazine increased mortality from chytridiomycosis, a disease causing worldwide amphibian declines.

Anthropologist examines the motivating factors behind hazing Posted: 23 Oct 2013 11:11 AM PDT It happens in military units, street gangs and even among athletes on sports teams. In some cultures, the rituals mark the transition from adolescence to adulthood. And in fraternities and sororities, it's practically a given. With a long history of seemingly universal acceptance, the practice of hazing is an enduring anthropological puzzle.

Ignorance is sometimes bliss Posted: 23 Oct 2013 11:11 AM PDT Evolutionary biologist W.D. Hamilton predicted that organisms ought to evolve the ability to discriminate degrees of kinship so as to refine their ability to direct help to individuals with whom they shared the most genes. But two biologists point out that there seem to be many cases where "a veil of ignorance" prevents organisms from gaining this kind of information, forcing them to consider a situation from the perspective of all members of their group.

Vacuums provide solid ground for new definition of kilogram Posted: 23 Oct 2013 11:11 AM PDT The weight of the kilogram may soon rest on the emptiness of a vacuum.

Deciding when 'not' to maximize profits: How and why some corporations sabotage their own subsidiaries Posted: 23 Oct 2013 11:11 AM PDT Corporate America doesn't always maximize profits -- companies sometimes deliberately leave money on the table in an effort to "get along" with and not upset their competitors. Corporate leaders "selectively intervene" in the everyday business of a subsidiary to deliberately sabotage decisions that could positively shift the balance of power in the marketplace. This "collusive behavior" and "mutual forbearance" reduces competitive aggressiveness in the market place and less competition usually hurts consumers.

Induced pluripotent stem cells reveal differences between humans and great apes Posted: 23 Oct 2013 11:10 AM PDT Researchers have, for the first time, taken chimpanzee and bonobo skin cells and turned them into induced pluripotent stem cells (iPSCs), a type of cell that has the ability to form any other cell or tissue in the body.

The galaxy is seen as it was just 700 million years after the Big Bang, when the universe was only about 5 percent of its current age of 13.8 billion years.

H5N1 bird flu genes show nature can pick worrisome traits Posted: 23 Oct 2013 10:17 AM PDT In the beginning, all flu viruses came from birds. Over time, the virus evolved to adapt to other animals, including humans, as natural selection favored viruses with mutations that allowed them to more readily infect the cells of new host species.

A simple test may catch early pancreatic cancer Posted: 23 Oct 2013 09:56 AM PDT Reporting on a small preliminary study, researchers say a simple blood test based on detection of tiny epigenetic alterations may reveal the earliest signs of pancreatic cancer, a disease that is nearly always fatal because it isn't usually discovered until it has spread to other parts of the body.

Older siblings' cells can be passed from female dogs to their puppies in the womb Posted: 23 Oct 2013 09:56 AM PDT Researchers have found that microchimerism, a condition where some people possess a small number of cells in their bodies that are not genetically their own, can be passed from a female dog to her offspring while they are still in the womb. Microchimerism most often occurs when a mother gives birth to a child. In some cases, cells from that child are left in the mothers' body and continue to live, despite being of a different genetic makeup than surrounding cells. Researchers have identified evidence that those cells can then be passed on to other children the mother may give birth to at a later time.

The reins of Casimir: Engineered nanostructures could offer way to control quantum effect Posted: 23 Oct 2013 09:56 AM PDT You might think that a pair of parallel plates hanging motionless in a vacuum just a fraction of a micrometer away from each other would be like strangers passing in the night -- so close but destined never to meet. Thanks to quantum mechanics, you would be wrong.

New radar system inspired by dolphins to detect hidden surveillance and explosive devices Posted: 23 Oct 2013 06:08 AM PDT Inspired by the way dolphins hunt using bubble nets, scientists have developed a new kind of radar that can detect hidden surveillance equipment and explosives. The twin inverted pulse radar (TWIPR) is able to distinguish true 'targets', such as certain types of electronic circuits that may be used in explosive or espionage devices, from 'clutter' (other metallic items like pipes, drinks cans, nails for example) that may be mistaken for a genuine target by traditional radar and metal detectors.

Super song learners: Mechanism for improving song learning in juvenile zebra finches uncovered Posted: 23 Oct 2013 06:07 AM PDT Most songbirds learn their songs from an adult model, mostly from the father. However, there are relatively large differences in the accuracy how these songs are copied. Researchers have now found in juvenile zebra finches a possible mechanism that is responsible for the differences in the intensity of song learning. They provided the nerve growth factor "BDNF" to the song control system in the brain. With this treatment the learning ability in juvenile males could be enhanced in such a way that they were able to copy the songs of the father as good as it had been observed in the best learners in a zebra finch nest.

Mass producing pocket labs Posted: 23 Oct 2013 06:07 AM PDT There is certainly no shortage of lab-on-a-chip (LOC) devices, but in most cases manufacturers have not yet found a cost-effective way to mass produce them. Scientists are now developing a platform for series production of these pocket laboratories.

Novel autism candidate genes identified Posted: 23 Oct 2013 06:07 AM PDT A scientific study identifies new genes involved in autism, a polygenic disorder that is difficult to diagnose and treat. Autism spectrum disorders represent a group of neurodevelopmental disorders which affect one out of 80-100 children. Autism's aetiology remains mainly unknown but there is strong evidence that genetic factors play a major role. International research has identified candidate genes that explain the origin and development of the disease.

Intercepting asteroids to avoid Armageddon Posted: 23 Oct 2013 06:07 AM PDT Potential asteroid impact on Earth can have disastrous consequences. In order to prevent such collisions, earthbound space objects must be deflected. This could be accomplished using a space probe to impact the asteroid.

Putting together the pieces of the Parkinson's puzzle Posted: 23 Oct 2013 06:07 AM PDT Parkinson's disease continues to puzzle physicians and biologists alike - even though it is well-established that symptoms like muscle tremors, rigidity, and immobility can all be traced back to the death of a certain type of brain cell called a dopaminergic neuron. The underlying cause of this cellular death is a complex web of interrelated genetic molecular processes as well as external factors. Now for the first time ever, researchers have published an interactive picture containing the current knowledge about the underlying genetic and molecular causes of Parkinson's disease.

Insights into how TB tricks the immune system could help combat the disease Posted: 23 Oct 2013 06:07 AM PDT Researchers have identified a potential way to manipulate the immune system to improve its ability to fight off tuberculosis (TB).

People tend to communicate with similar people, even more than previously thought Posted: 23 Oct 2013 06:07 AM PDT People's tendency to communicate with similar people is stronger than earlier believed, which restricts the flow of information and ideas in social networks.

People don't put a high value on climate protection Posted: 23 Oct 2013 06:07 AM PDT People are bad at getting a grip on collective risks. Climate change is a good example of this: the annual climate summits have so far not led to specific measures. The reason for this is that people attach greater value to an immediate material reward than to investing in future quality of life. Therefore, cooperative behavior in climate protection must be more strongly associated with short-term incentives such as rewards or being held in high esteem.

A trace of memory, explored Posted: 23 Oct 2013 06:05 AM PDT Most of our behavior – and thus our personality – is shaped by previous experience. To store the memory of these experiences and to be able to retrieve the information at will is therefore considered one of the most basic and important functions of the brain. The current model in neuroscience poses that memory is stored as long-lasting anatomical changes in synapses, the specialized structures by which nerve cells connect and signal to each other.

The molecular clock of the common buzzard: Influence of genes on dispersal behavior revealed Posted: 23 Oct 2013 06:05 AM PDT Be it hibernation or the routes of migratory birds: all animal behavior that is subject to annual rhythms is controlled by a molecular clock. Although this has been known for a long time, in many cases it is still unclear how far genes are involved in setting this internal clock. Up to now, this also applied to the common buzzard and its migration from parental breeding grounds.
