A Tailored Pair of Genes

*For ancient plants, two genes were definitely better than one*

In the wake of the disaster that killed the dinosaurs, the ancestors of today’s crop plants reinvented themselves.

They doubled their genomes, and in that single act set the stage for feeding the world 60 million years later.

In a study published in the Nov. 16 issue of the journal Nature, researchers from the University of Minnesota and other institutions recount how sequencing the genome of a model, alfalfa-like legume revealed the monumental benefits that flowed when the ancestor of legumes acquired an extra copy of every gene.

UCLA Team Develops Highly Efficient Method for Creating Flexible, Transparent Electrodes

As the market for liquid crystal displays and other electronics continues to drive up the price of indium — the material used to make the indium tin oxide (ITO) transparent electrodes in these devices — scientists have been searching for a less costly and more dynamic alternative, particularly for use in future flexible electronics.

At a Loss for Words

*Research into aphasia – the inability to speak or write well-formulated sentences and words – is strong at the UA. Researchers have received $2 million toward the study of the condition.*

The National Institutes of Health have awarded the University of Arizona’s Aphasia Research Project in the department of speech, language and hearing sciences a $2 million grant to research communication impairments in adults who have suffered brain injury.

Aphasia – the inability to speak or write well-formulated sentences and words – is a common result of a stroke or a traumatic brain injury such as the one suffered by Rep. Gabrielle Giffords, who was shot in the head earlier this year. The bullet damaged regions of the brain that are critical for language and control of the right side of the body. (more…)

Want Fuel Cells? Think Outside the Hydrogen Tank

In this week’s Science magazine, an energy expert advocates investing in “the other fuel cell” to reduce reliance on fossil fuels now, not in decades.

COLLEGE PARK, Md.– When most people hear the words “fuel cell,” they think of eco-friendly, hydrogen-powered cars that emit nothing more than water. (more…)

Yale Engineers Invent Novel Way to Sort Microparticles – By Size

Engineers at Yale University have developed a new, highly efficient technique for separating, sorting, and concentrating synthetic microscopic particles within complex fluids based on size.

The new technique suggests the possibility of significant clinical, diagnostic, and pharmaceutical applications, such as isolating rare liquid-borne pathogens, monitoring tumor cells in bloodstreams, and rapidly assessing blood cell counts, for example. (more…)

NASA Probe Data Show Liquid Water Evidence on Europa

PASADENA, Calif. — Data from a NASA planetary mission have provided scientists evidence of what appears to be a body of liquid water, equal in volume to the North American Great Lakes, beneath the icy surface of Jupiter’s moon, Europa.

The data suggest there is significant exchange between Europa’s icy shell and the ocean beneath. This information could bolster arguments that Europa’s global subsurface ocean represents a potential habitat for life elsewhere in our solar system. The findings are published in the scientific journal Nature. (more…)
