Secret to raising well behaved teens? Maximize their zzzzz's Posted: 26 Sep 2014 05:58 AM PDT While American pediatricians warn sleep deprivation can stack the deck against teenagers, a new study reveals youth's irritability and laziness aren't down to attitude problems but lack of sleep. This paper exposes the negative consequences of sleep deprivation caused by early school bells, and shows that altering education times not only perks up teens' mood, but also enhances learning and health.

Turning the Moon into a cosmic ray detector Posted: 26 Sep 2014 05:58 AM PDT Scientists are to turn the Moon into a giant particle detector to help understand the origin of Ultra-High-Energy (UHE) cosmic rays -- the most energetic particles in the Universe. The origin of UHE cosmic rays is one of the great mysteries in astrophysics. Nobody knows where these extremely rare cosmic rays come from or how they get their enormous energies. Physicists detect them on Earth at a rate of less than one particle per square kilometer per century.

Mechanized human hands: System designed to improve hand function lost to nerve damage Posted: 25 Sep 2014 02:26 PM PDT Engineers have developed and successfully demonstrated the value of a simple pulley mechanism to improve hand function after surgery. The device, tested in cadaver hands, is one of the first instruments ever created that could improve the transmission of mechanical forces and movement while implanted inside the body.

On the road to artificial photosynthesis: Study reveals key catalytic factors in carbon dioxide reduction Posted: 25 Sep 2014 12:08 PM PDT The excessive atmospheric carbon dioxide that is driving global climate change could be harnessed into a renewable energy technology that would be a win for both the environment and the economy. That is the lure of artificial photosynthesis in which the electrochemical reduction of carbon dioxide is used to produce clean, green and sustainable fuels. However, finding a catalyst for reducing carbon dioxide that is highly selective and efficient has proven to be a huge scientific challenge. New experimental results have revealed the critical influence of the electronic and geometric effects in the carbon dioxide reduction reaction and might help make the problem easier to tackle.

Agonizing rabies deaths can be stopped worldwide Posted: 25 Sep 2014 11:12 AM PDT Ridding the world of rabies in humans is cost-effective and achievable through mass dog vaccination programs, an international team of researchers says. A rabies vaccine has long existed. Even so, the disease kills an estimated 69,000 people worldwide -- that's 189 each day. Forty percent of them are children, mostly in Africa and Asia. The disease is spread primarily through the saliva of infected dogs. Once a person develops symptoms, the chance that he or she will die is nearly 100-percent.

Chemists recruit anthrax to deliver cancer drugs Posted: 25 Sep 2014 07:09 AM PDT With some tinkering, a deadly protein becomes an efficient carrier for antibody drugs, researchers have discovered. "Anthrax toxin is a professional at delivering large enzymes into cells," says one researcher. "We wondered if we could render anthrax toxin nontoxic, and use it as a platform to deliver antibody drugs into cells."

Live long and phosphor: Blue LED breakthrough for efficient electronics Posted: 25 Sep 2014 05:14 AM PDT In a step that could lead to longer battery life in smartphones and lower power consumption for large-screen televisions, researchers have extended the lifetime of blue organic light emitting diodes by a factor of 10.

Think you have Alzheimer's? You just might be right, study says Posted: 24 Sep 2014 06:18 PM PDT New research suggests that people who notice their memory is slipping may be on to something. The research appears to confirm that self-reported memory complaints are strong predictors of clinical memory impairment later in life.

False memories could be a side-effect of human ability to learn rules Posted: 24 Sep 2014 08:30 AM PDT Our tendency to create false memories could be related to our ability to learn rules according to new research. New research suggests that individuals who are particularly good at learning rules and classifying objects by common properties are also particularly prone to false memory illusions.

The fickle El Niño of 2014 Posted: 23 Sep 2014 12:36 PM PDT Prospects have been fading for an El Niño event in 2014, but now there's a glimmer of hope for a very modest comeback. Scientists warn that unless these developing weak-to-modest El Niño conditions strengthen, the drought-stricken American West shouldn't expect any relief.

Termites evolved complex bioreactors 30 million years ago Posted: 23 Sep 2014 07:16 AM PDT Achieving complete breakdown of plant biomass for energy conversion in industrialized bioreactors remains a complex challenge, but new research shows that termite fungus farmers solved this problem more than 30 million years ago. The new insight reveals that the great success of termite farmers as plant decomposers is due to division of labor between a fungus breaking down complex plant components and gut bacteria contributing enzymes for final digestion.

Video blinds us to the evidence, study finds Posted: 23 Sep 2014 06:02 AM PDT Where people look when watching video evidence varies wildly and has profound consequences for bias in legal punishment decisions, a team of researchers at two Law Schools has found.

Intervention in 6-month-olds with autism eliminates symptoms, developmental delay Posted: 09 Sep 2014 06:37 AM PDT Treatment at the earliest age when autism spectrum disorder is detectable -- in infants as young as 6 months old -- significantly reduces symptoms so that by age 3 most who received the therapy had neither autism nor delay, a research study has found.

Resveratrol may be natural exercise performance enhancer Posted: 19 Jun 2012 07:59 PM PDT A natural compound found in some fruits, nuts and red wine may enhance exercise training and performance, demonstrates newly published medical research.
