Solar-cell efficiency improved with new polymer devices
New light has been shed on solar power generation using devices made with polymers. Researchers identified a new polymer -- a type of large molecule that forms plastics and other familiar materials -- which improved the efficiency of solar cells. The group also determined the method by which the polymer improved the cells' efficiency. The polymer allowed electrical charges to move more easily throughout the cell, boosting the production of electricity -- a mechanism never before demonstrated in such devices.

Climate Change: Dwindling wind may tip predator-prey balance
Rising temperatures and shifting precipitation patterns may get the lion’s share of our climate change attention, but predators may want to give some thought to wind, according to a zoologist’s study, which is among the first to demonstrate the way “global stilling” may alter predator-prey relationships.

Domestic violence likely more frequent for same-sex couples
Domestic violence occurs at least as frequently, and likely even more so, between same-sex couples compared to opposite-sex couples, according to a new review of research. Abuse is underreported in same-sex couples due to the stigma of sexual orientation, researchers note.

Possible 6,800 new Ebola cases this month, research predicts
A possible 6,800 new Ebola cases this are predicted this month, as suggested by researchers who used modelling analysis to come up with their figures. The rate of new cases significantly increased in August in Liberia and Guinea, around the time that a mass quarantine was put in place, indicating that the mass quarantine efforts may have made the outbreak worse than it would have been otherwise.

Pathway that contributes to Alzheimer's disease revealed by research
A defect in a key cell-signaling pathway has been discovered that researchers say contributes to both overproduction of toxic protein in the brains of Alzheimer’s disease patients as well as loss of communication between neurons — both significant contributors to this type of dementia.

Fingertip sensor gives robot unprecedented dexterity
Researchers have equipped a robot with a novel tactile sensor that lets it grasp a USB cable draped freely over a hook and insert it into a USB port.

Gene responsible for traits involved in diabetes discovered
A new gene associated with fasting glucose and insulin levels in rats, mice and in humans, has been discovered by researchers. 29 million Americans have diabetes -- more than nine percent of the total population. It is the 7th leading cause of death, and experts estimate diabetes is an underreported cause of death because of the comorbidities and complications associated with the disease.

Soft robotics 'toolkit' features everything a robot-maker needs
A new resource provides both experienced and aspiring researchers with the intellectual raw materials needed to design, build, and operate robots made from soft, flexible materials. With the advent of low-cost 3-D printing, laser cutters, and other advances in manufacturing technology, soft robotics is emerging as an increasingly important field.

Reflected smartphone transmissions enable gesture control
Engineers have developed a new form of low-power wireless sensing technology that lets users "train" their smartphones to recognize and respond to specific hand gestures near the phone.

Hadrosaur with huge nose discovered: Function of dinosaur's unusual trait a mystery
Call it the Jimmy Durante of dinosaurs -- a newly discovered hadrosaur with a truly distinctive nasal profile. The new dinosaur, named Rhinorex condrupus by paleontologists, lived in what is now Utah approximately 75 million years ago during the Late Cretaceous period.
