How sweet it is: Bioenergy advanced by new tool

Posted: 28 Jul 2014 08:33 AM PDT

Researchers have developed a powerful new tool that can help advance the genetic engineering of 'fuel' crops for clean, green and renewable bioenergy -- an assay that enables scientists to identify and characterize the function of nucleotide sugar transporters, critical components in the biosynthesis of plant cell walls.

New meaning to refrigerator magnets: Magnets may act as wireless cooling agents

Posted: 28 Jul 2014 07:47 AM PDT

The magnets cluttering the face of your refrigerator may one day be used as cooling agents, according to a new theory. A magnetically driven refrigerator would require no moving parts, unlike conventional iceboxes that pump fluid through a set of pipes to keep things cool.

Wearable device for early detection of common diabetes-related neurological condition

Posted: 28 Jul 2014 06:44 AM PDT

Thanks to a small, wearable device that can hang on a pair of eyeglasses, a common complication of diabetes may get caught sooner. Researchers have developed a pupillometer that scans the patient's eyes for early signs of diabetic autonomic neuropathy -- a condition that progressively affects the autonomic nerves controlling vital organs. This kind of early detection enables early treatment, leading to far better health outcomes for the patient.

Glow in space is evidence of a hot bubble in our galaxy

Posted: 28 Jul 2014 06:44 AM PDT

A recent study shows that the emission is dominated by the local hot bubble of gas -- 1 million degrees -- with, at most, 40 percent of emission originating within the solar system. The findings should put to rest the disagreement about the origin of the X-ray emission and confirm the existence of the local hot bubble.

Building 'invisible' materials with light

A new technique which uses light like a needle to thread long chains of particles could help bring sci-fi concepts such as cloaking devices one step closer to reality.

New tools help neuroscientists analyze 'big data'

Posted: 27 Jul 2014 01:57 PM PDT

New technologies for monitoring brain activity are generating unprecedented quantities of information. That data may hold new insights into how the brain works -- but only if researchers can interpret it. To help make sense of the data, neuroscientists can now harness the power of distributed computing with Thunder, a library of tools.

'Holy grail' of battery design achieved: Stable lithium anode

Posted: 27 Jul 2014 01:57 PM PDT

Researchers report that they have taken a big step toward accomplishing what battery designers have been trying to do for decades -- design a pure lithium anode. All batteries have three basic components: an electrolyte to provide electrons, an anode to discharge those electrons, and a cathode to receive them. The nanosphere layer of a newly created battery design resembles a honeycomb: it creates a flexible, uniform and non-reactive film that protects the unstable lithium from the drawbacks that have made it such a challenge.

Gene changes in breast cancer cells pinpointed with new computational method

Posted: 24 Jul 2014 11:42 AM PDT

Computer scientists working with high-throughput data generated by breast cancer biologists have devised a computational method to determine how gene networks are rewired as normal breast cells turn malignant and as they respond to potential cancer therapy agents.

New radiological signs of gastric lap band slippage identified

Posted: 24 Jul 2014 09:44 AM PDT

Two previously undescribed radiological signs of potentially life-threatening slippage of laparoscopically adjustable gastric bands have been identified by researchers.

Novel technologies advance brain surgery to benefit patients

Posted: 24 Jul 2014 09:36 AM PDT

In a milestone procedure, neurosurgeons have integrated advanced 3D imaging, computer simulation and next-generation surgical tools to perform a highly complex brain surgery through a small incision to remove deep-seated tumors. "These minimally invasive approaches permit smaller incisions and a shorter recovery. In this case, the patient was able to go home the day after the successful removal of multiple brain tumors," said one expert.
