UCLA and University of Connecticut scientists design supercapacitor that could make pacemakers and other instruments safer and more durable

Researchers from UCLA and the University of Connecticut have designed a new biofriendly energy storage system called a biological supercapacitor, which operates using charged particles, or ions, from fluids in the human body. The device is harmless to the body’s biological systems, and it could lead to longer-lasting cardiac pacemakers and other implantable medical devices. (more…)

Multicolored laser light is the key to cooling these atoms to nearly absolute zero

UCLA physicists have shown that shining multicolored laser light on rubidium atoms causes them to lose energy and cool to nearly absolute zero. This result suggests that atoms fundamental to chemistry, such as hydrogen and carbon, could also be cooled using similar lasers, an outcome that would allow researchers to study the details of chemical reactions involved in medicine.

New technique will accelerate genetic characterization of photosynthesis

Stanford, CA — Photosynthesis provides fixed carbon and energy for nearly all life on Earth, yet many aspects of this fascinating process remain mysterious. For example, little is known about how it is regulated in response to changes in light intensity. More fundamentally, we do not know the full list of the parts of the molecular machines that perform photosynthesis in any organism.

A type of single-cell green algae called Chlamydomonas reinhardtii is a leading subject for photosynthesis research. Despite its importance in the research world, few tools are available for characterizing the functions of its genes. (more…)

A better water wing to harvest tidal energy

The eternal ebb and flow of tides — 24 x 7 x 365 — makes them a dependable source of energy, but how to harness all that, especially in shallow water? Shreyas Mandre and colleagues at Brown have developed an efficient water wing and optimized its performance with a “secret sauce.”

PROVIDENCE, R.I. [Brown University] — When it comes to raw power and absolute reliability, it doesn’t get much better than the tides. That’s why tidal power is such an attractive option as a renewable form of energy. But designing a device to gather tidal energy in shallow water, where the ebb and flow move fastest and the energy potential is highest, has proven problematic. (more…)

How Did Life Arise? Fuel Cells May Have Answers

How life arose from the toxic and inhospitable environment of our planet billions of years ago remains a deep mystery. Researchers have simulated the conditions of an early Earth in test tubes, even fashioning some of life’s basic ingredients. But how those ingredients assembled into living cells, and how life was first able to generate energy, remain unknown.

A new study led by Laurie Barge of NASA’s Jet Propulsion Laboratory in Pasadena, Calif., demonstrates a unique way to study the origins of life: fuel cells. (more…)
