ANN ARBOR, Mich.— In an egg carton of laser light, University of Michigan physicists can trap giant Rydberg atoms with up to 90 percent efficiency, an achievement that could advance quantum computing and terahertz imaging, among other applications. (more…)
*Joint BioEnergy Institute Researchers Develop CAD-Type Tools for Engineering RNA Control Systems*
The computer assisted design (CAD) tools that made it possible to fabricate integrated circuits with millions of transistors may soon be coming to the biological sciences. Researchers at the U.S. Department of Energy (DOE)’s Joint BioEnergy Institute (JBEI) have developed CAD-type models and simulations for RNA molecules that make it possible to engineer biological components or “RNA devices” for controlling genetic expression in microbes. This holds enormous potential for microbial-based sustainable production of advanced biofuels, biodegradable plastics, therapeutic drugs and a host of other goods now derived from petrochemicals.

Just in time for the holidays, astronomers have come across a new image from NASA’s Wide-field Infrared Survey Explorer, or WISE, that some say resembles a wreath. You might even think of the red dust cloud as a cheery red bow, and the bluish-white stars as silver bells. This star-forming nebula is named Barnard 3. Baby stars are being born throughout the dusty region, while the “silver bell” stars are located both in front of, and behind, the nebula. (more…)
RNA editing is a key step in gene expression. Scientists at Brown University report in Nature Methods that they have engineered a gene capable of visually displaying the activity of the key enzyme ADAR in living fruit flies.
PROVIDENCE, R.I. [Brown University] — To track what they can’t see, pilots look to the green glow of the radar screen. Now biologists monitoring gene expression, individual variation, and disease have a glowing green indicator of their own: Brown University biologists have developed a “radar” for tracking ADAR, a crucial enzyme for editing RNA in the nervous system.

AUSTIN, Texas — A new study co-authored by a University of Texas at Austin psychology professor suggests that self-deception may help men succeed in the mating game, while women will benefit more from effective communication. (more…)
A North Carolina State University invention has significant potential to improve the efficiency of solar cells and other technologies that derive energy from light.
Dr. Ahmed El-Shafei’s research group invented a new “sensitizer,” or dye, that harvests more ambient and solar light than any dyes currently on the market for use in dye-sensitized solar cells (DSSCs). (more…)
*Americans typically spend $70 billion more in December than in November and January*
Americans typically spend $70 billion more in December than in the average of November and January (the months around December). In a recent National Science Foundation-sponsored interview, Joel Waldfogel, the Carlson School’s Frederick R. Kappel Professor of Applied Economics at the University of Minnesota uses that increase to measure the amount of holiday gift-giving. This level of spending is lower than in other countries. “We’re about the 20th largest in terms of countries in the world,” said Waldfogel, referencing how much U.S. December spending increases.

Stanford, CA — Plant roots are fascinating plant organs – they not only anchor the plant, but are also the world’s most efficient mining companies. Roots live in darkness and direct the activities of the other organs, as well as interact with the surrounding environment. Charles Darwin posited in The Power of Movement of Plants that the root system acts as a plant’s brain. (more…)
