Halogen bonding for selective electrochemical separation, path to sustainable chemical processing demonstrated      (via sciencedaily.com)     Original source 

A team has reported the first demonstration of selective electrochemical separation driven by halogen bonding. This was achieved by engineering a polymer that modulates the charge density on a halogen atom when electricity is applied. The polymer then attracts only certain targets -- such as halides, oxyanions, and even organic molecules -- from organic solutions, a feature that has important implications for pharmaceuticals and chemical synthesis processes.

Rewriting the evolutionary history of critical components of the nervous system      (via sciencedaily.com)     Original source 

A new study has rewritten the conventionally understood evolutionary history of certain ion channels -- proteins critical for electrical signaling in the nervous system. The study shows that the Shaker family of ion channels were present in microscopic single cell organisms well before the common ancestor of all animals and thus before the origin of the nervous system.

Taking a 'one in a million' shot to tackle dopamine-linked brain disorders      (via sciencedaily.com)     Original source 

With the help of a tiny, transparent worm called Caenorhabditis elegans, researchers have identified novel players in dopamine signaling by taking advantage of a powerful platform generated via the Million Mutation Project (MMP) for the rapid identification of mutant genes based on their functional impact. They can seek insights from simpler organisms whose genes bear striking similarity to those found in humans and where opportunities for genetic insights to disease can be pursued more efficiently and inexpensively.

Increasing solid-state electrolyte conductivity and stability using helical structure      (via sciencedaily.com)     Original source 

Solid-state electrolytes have been explored for decades for use in energy storage systems and in the pursuit of solid-state batteries. These materials are safer alternatives to the traditional liquid electrolyte -- a solution that allows ions to move within the cell -- used in batteries today. However, new concepts are needed to push the performance of current solid polymer electrolytes to be viable for next generation materials.

Mix of factors prompts owl monkeys to leave their parents      (via sciencedaily.com)     Original source 

There comes a point in the lives of young owl monkeys when they leave their parents and strike out on their own to find a mate. In a new study of a wild population of Azara's owl monkeys in northern Argentina, researchers reveal that a combination of social and ecological factors influences when these tree-dwelling monkeys peel away from their parents and siblings. According to their findings -- which were based on 25 years of genetic and demographic data for several generations of owl monkeys, covering more than 330 individuals -- none of the individuals, regardless of their sex, reproduced in the same group where they were born. In all cases, the researchers found, the animals either departed from their natal group or died before reproducing.

Stacking molecules like plates improves organic solar device performance      (via sciencedaily.com)     Original source 

Researchers found that how well light-converting molecules stack together in a solid is important for how well they convert light into electric current. A rigid molecule that stacked well showed excellent electricity generation in an organic solar cell and photocatalyst, easily outperforming a similar flexible molecule that did not stack well. This new way of improving the design of molecules could be used to pioneer the next generation of light-converting devices.
