Study finds essential-oil blend reduces salmonella contamination

Posted: 15 Nov 2012 06:36 AM PST

Oil and water may not mix, but a University of Georgia study found feeding chickens a blend of plant-based oils in their drinking water can help prevent salmonella contamination before the meat reaches the dinner table—or even the grocery store.

Salmonella is a bacterium that causes an estimated 1 million cases of foodborne illness in the U.S. each year, said Walid Alali, a food safety scientist with the UGA Center for Food Safety in Griffin.

Structure of Enzyme Topoisomerase II Alpha Unravelled Providing Basis for More Accurate Design of Chemotherapeutic Drugs

Posted: 15 Nov 2012 05:10 AM PST

A group of researchers at the University of California, Berkeley have for the first time described the structure of the active site core of topoisomerase II alpha, an important target for anti-cancer drugs.

Researchers gain new insights into the behaviour of the coconut crab Birgus latro

Posted: 15 Nov 2012 05:03 AM PST

Researchers from Jena and Greifswald used GPS satellites for a long-term behavioural monitoring of land crab migration on Christmas Island. In cooperation with colleagues from the Zoological Institute at the University of Greifswald, scientists from the Max Planck Institute for Chemical Ecology in Jena, Germany, used a GPS-based telemetric system to analyze movements of freely roaming robber crabs, which is the first large-scale study of any arthropod using GPS technology to monitor behaviour.

New ancient shark species gives insight into origin of great white

Posted: 14 Nov 2012 04:15 PM PST

The great white shark is one of the largest living predatory animals and a magnet for media sensationalism, yet its evolutionary history is as misunderstood as its role as a menace.

Novel process to detect proteins could simplify kidney disease detection

Posted: 14 Nov 2012 04:08 PM PST

Detecting whether a patient will have acute kidney injury could become as simple as dipping a paper test strip printed with gold nanorods into a urine sample, a team of Washington University in St. Louis researchers has found.

How Cells in the Nose Detect Odors

Posted: 14 Nov 2012 03:54 PM PST

The human nose has millions of olfactory neurons grouped into hundreds of different neuron types. Each of these neuron types expresses only one odorant receptor, and all neurons expressing the same odorant receptor plug into one region in the brain, an organization that allows for specific odors to be sensed.

Cilia guide neuronal migration in developing brain

Posted: 14 Nov 2012 03:46 PM PST

A new study demonstrates the dynamic role cilia play in guiding the migration of neurons in the embryonic brain. Cilia are tiny hair-like structures on the surfaces of cells, but in the brain they are acting more like radio antennae.

In developing mouse embryos, researchers were able to see cilia extending and retracting as neurons migrate. The cilia appear to be receiving signals needed for neurons to find their places.

Discovery Could Lead to Faster Diagnosis For Some Chronic Fatigue Syndrome Cases

Posted: 14 Nov 2012 02:52 PM PST

For the first time, researchers have landed on a potential diagnostic method to identify at least a subset of patients with chronic fatigue syndrome (CFS), a complex disorder with no known definitive cause or cure.

In a pilot study of six patients, scientists detected specific antibodies linked to latent Epstein-Barr virus reactivation in blood samples from people who had experienced classic CFS symptoms and responded to antiviral treatment. Control blood samples from 20 healthy people showed no such antibodies.

Gene Nearly Triples Risk of Alzheimer's, Global Team Including Mayo Clinic Finds

Posted: 14 Nov 2012 02:46 PM PST

A gene so powerful it nearly triples the risk of Alzheimer's disease has been discovered by an international team including researchers from Mayo Clinic. It is the most potent genetic risk factor for Alzheimer's identified in the past 20 years. The findings were reported Wednesday in the online edition of the New England Journal of Medicine.

Unkindness linked to alcohol, drug abuse in black populations

Posted: 14 Nov 2012 12:50 PM PST

Blacks who feel mistreated and discriminated against are more likely to abuse alcohol and illegal drugs, and a new study from Purdue University shows this usage can become a problematic pattern.

Georgia Tech Releases Cyber Threats Forecast for 2013

Posted: 14 Nov 2012 12:47 PM PST

The year ahead will feature new and increasingly sophisticated means to capture and exploit user data, escalating battles over the control of online information and continuous threats to the U.S. supply chain from global sources. Those were the findings made by the Georgia Tech Information Security Center (GTISC) and the Georgia Tech Research Institute (GTRI) in today's release of the Georgia Tech Emerging Cyber Threats Report for 2013.

Exploring the Financial Costs of Sadness

Posted: 14 Nov 2012 11:43 AM PST

Your emotions can certainly impact your decisions, but you might be surprised by the extent to which your emotions affect your pocketbook. New research from psychological scientist Jennifer Lerner of the Harvard Kennedy School of Government and colleagues Yi Le and Elke U. Weber of Columbia University explores how impatience brought on by sadness can in turn produce substantial financial loss. The study is published in Psychological Science, a journal of the Association for Psychological Science.

Study links exposure to light at night to depression, learning issues

Posted: 14 Nov 2012 11:38 AM PST

For most of history, humans rose with the sun and slept when it set. Enter Thomas Edison, and with a flick of a switch, night became day, enabling us to work, play, and post cat and kid photos on Facebook into the wee hours.

Engineering a Photo-Switch for Nerve Cells in the Eye and Brain

Posted: 14 Nov 2012 08:33 AM PST

Chemists and vision scientists at the University of Illinois at Chicago have designed a light-sensitive molecule that can stimulate a neural response in cells of the retina and brain -- a possible first step to overcoming degenerative eye diseases like age-related macular degeneration, or to quieting epileptic seizures.

Their results are reported online in the journal Nature Communications.

Macular degeneration, the leading cause of vision loss in people over 50, is caused by loss of light-sensitive cells in the retina -- the rods and cones.

Kicking the Habit – New Research Examines The Barriers To Quitting Smoking For Smokers With Asthma

Posted: 14 Nov 2012 08:28 AM PST

A new University of Cincinnati study examines how anxiety sensitivity can thwart the efforts of smokers with asthma to quit smoking. This new direction of research from Alison McLeish, a UC assistant professor of psychology, will be presented on Nov.17, at the 46th annual convention of the Association of Behavioral and Cognitive Therapies (ABCT) in National Harbor, Md.

Research Examines Why Some People Are Afraid To Relax

Posted: 14 Nov 2012 08:25 AM PST

Although many people look forward to getting away on vacation or just putting their feet up at home, there are others who can get as anxious about taking time to relax as they would if they were delivering a national address.
relax.

Nanometer-scale diamond tips improve nano-manufacturing

Posted: 14 Nov 2012 08:22 AM PST

One of the most promising innovations of nanotechnology has been the ability to perform rapid nanofabrication using nanometer-scale tips. The fabrication speed can be dramatically increased by using heat. High speed and high temperature have been known to degrade the tip… until now.
