Improving battery performance testing

Thu, 31/03/2016 - 5:44pm
Scientists have demonstrated that the placement and type of a tiny measurement device called a reference electrode enhances the quantity and quality of information that can be extracted from lithium-ion battery cells during cycling.

Proving the genetic code's flexibility

Thu, 31/03/2016 - 5:44pm
Three-letter codons in a genome sequence can represent one of the 20 regularly used amino acids or stops. Scientists have discovered that microorganisms recognize more than one codon for selenocysteine. The finding adds credence to recent studies indicating that an organism's genetic vocabulary is not as constrained as had been long held.

Researchers tackle mystery of protein folding

Thu, 31/03/2016 - 5:43pm
A chemistry approach is solving some of the riddles of the complex protein-building process of folding. When it goes right, strings of amino acids become well-ordered, three-dimensional proteins in a split second. When it goes awry, though, it's the first step of many serious diseases.

Brain cancer: Two essential amino acids might hold key to better outcomes

Thu, 31/03/2016 - 5:43pm
The altered metabolism of two essential amino acids helps drive the development of the most common and lethal form of brain cancer, new research has discovered. The findings suggest new ways to treat the malignancy, slow its progression and reveal its extent more precisely. The study shows that in glioblastoma, the essential amino acids methionine and tryptophan are abnormally metabolized due to the loss of key enzymes in GBM cells.

How the brain processes emotions

Thu, 31/03/2016 - 5:43pm
A new study reveals how two populations of neurons in the brain contribute to the brain's inability to correctly assign emotional associations to events. Learning how this information is routed and misrouted could shed light on mental illnesses including depression, addiction, anxiety, and posttraumatic stress disorder.

Scientists discover a missing link between tau and memory loss

Thu, 31/03/2016 - 5:43pm
Scientists have long known that the protein tau is involved in dementia, but until recently, they did not understand how it hindered cognitive function. In a new study, researchers reveal how tau disrupts a cell's ability to strengthen connections with other cells, preventing memories from forming.

Scientists work their magic on 'shrunken finger illusion'

Thu, 31/03/2016 - 5:34pm
What happens when you rest a chopped ping pong ball on your finger and look at it from above? Experimental psychologists have shown that our visual system fills in the bottom part of the ball, even though we know it's missing. This makes our finger feel unusually short, as if to compensate for the 'complete' ball. The findings indicate that the completion is due to our visual system, not our imagination.

Sweet tooth? Flies have it too -- new study shows how they know what to eat and when to stop

Thu, 31/03/2016 - 5:34pm
In studying the eating behavior of fruit flies, scientists have discovered a set of throat neurons that regulate food intake based on how hungry the flies are and whether they've had enough sugar. A similar neural circuit may exist in vertebrates, like us.

3-D 'mini-retinas' grown from mouse and human stem cells

Thu, 31/03/2016 - 5:34pm
Stem cell science has progressed so that researchers can now share recipes for making human retinas -- the part of the eye that is sensitive to light. Researchers now have another efficient way to make 3-D retina organoids, which mimic the organ's tissue organization, from mouse or human stem cells. Their version of 'mini-retinas' offers new perspectives on retina growth, injury, and repair.

Virus evolution differs by species of mosquito carrier

Thu, 31/03/2016 - 5:34pm
A new study on how the West Nile virus evolves in four species of mosquitos shows that viruses accumulate mutations in their insect carriers that reduce how well they reproduce when passed on to a bird host. Viruses carried by one of the tropical species were best able to maintain their reproductive fitness and thus spread. The study could help in the prediction of future viral outbreaks.

A fossilized snake shows its true colors

Thu, 31/03/2016 - 5:34pm
Ten million years ago, a green and black snake lay coiled in the Spanish undergrowth. Once, paleontologists would have been limited by its colorless fossil remains, but now they know what the snake looked like and can guess how it acted. Researchers have discovered that some fossils can retain evidence of skin color from multiple pigments and structural colors, aiding research into the evolution and function of color.

Mom's smoking alters fetal DNA

Thu, 31/03/2016 - 5:33pm
A study of over 6,000 mothers and their newborn children -- one of the largest studies of its kind -- solidifies the evidence that smoking cigarettes while pregnant chemically modifies a fetus' DNA, mirroring patterns seen in adult smokers. The researchers also identify new development-related genes affected by smoking. The work suggests a potential explanation for the link between smoking during pregnancy and health complications in children.

Waste stream to energy source: What if America’s next big fuel source is its trash?

Thu, 31/03/2016 - 4:59pm
Researchers want to create energy conversion technologies designed to mine the carbon out of waste processes that traditionally have been an environmental burden to the planet.

Lead in soil another known factor in Flint

Thu, 31/03/2016 - 4:47pm
A new study has found that higher rates of Flint children showed elevated lead levels in their blood during drier months of the year, even before the switch to a new water supply. The findings suggest that lead contaminated soil is most likely the culprit especially in the older, more industrial areas of the city.

Addiction associated with poor awareness of others, study shows

Thu, 31/03/2016 - 4:47pm
Adolescents with severe alcohol and other drug problems have a low regard for others, as indicated by higher rates of driving under the influence and having unprotected sex with a history of sexually transmitted disease, research shows. The findings also showed that they are less likely to volunteer their time helping others, an activity that she has been shown to help adult alcoholics stay sober.
