World's most sensitive dark matter detector completes search

Thu, 21/07/2016 - 11:26am
The Large Underground Xenon (LUX) dark matter experiment, which operates beneath a mile of rock at the Sanford Underground Research Facility in the Black Hills of South Dakota, has completed its search for the missing matter of the universe. At a meeting in the UK, LUX scientific collaborators presented the results from the detector's final 20-month run.

Fire clues in cave dripwater

Thu, 21/07/2016 - 11:26am
When mineral-rich water drips from a cave's ceiling over centuries and millennia, it forms rocky cones that hold clues to the Earth's past climate. Now, researchers in Australia and the UK have found that these structures can also help trace past wildfires that burned above the cave.

Glutamate levels in the brain may be linked to alcohol craving

Thu, 21/07/2016 - 1:54am
Craving consists of cognitive, emotional, and behavioral elements related to a desire to drink alcohol, and can be experienced during intoxication, withdrawal, and/or prior to relapse. Different types of craving are hypothesized to be associated with different neurotransmitter systems. For example, reward craving may be mediated by dopamine and opioids, obsessive craving by serotonin, and relief craving by glutamate. A new study used magnetic resonance spectroscopy (1H-MRS) to examine the correlation between craving and glutamate levels in the left dorsolateral prefrontal cortex (LDLPFC) of patients with alcohol use disorders (AUDs).

Diversifying clinical science to represent diverse populations

Thu, 21/07/2016 - 1:53am
Despite increasing attention to issues of diversity in scientific research, participant populations in behavioral science tend to be relatively homogeneous. A special series in Clinical Psychological Science highlights the importance of broadening the traditional scope of clinical science research, advancing the field so that it can adequately address the needs and concerns of diverse populations.

Come on baby, (re)light my fire

Thu, 21/07/2016 - 1:53am
Many couples find that their sexual desire has dwindled over time. It's not unusual for partners who could not keep their hands off each to gradually lose interest. But new research indicates that there are ways that couples can sustain -- or relight -- their passion.

Titanium and gold equals new gold standard for artificial joints

Thu, 21/07/2016 - 1:51am
Titanium is the leading material for artificial knee and hip joints because it's strong, wear-resistant and nontoxic, but an unexpected discovery by physicists shows that the gold standard for artificial joints can be improved with the addition of some actual gold.

Exercise as effective as surgery for middle aged patients with knee damage

Thu, 21/07/2016 - 1:51am
Exercise therapy is as effective as surgery for middle aged patients with a common type of knee injury known as meniscal tear (damage to the rubbery discs that cushion the knee joint), finds a new study.

Imaging after thyroid cancer treatment does not necessarily mean better outcomes

Thu, 21/07/2016 - 1:51am
More imaging after thyroid cancer treatment identifies recurrence, but it does not always improve survival, a new study suggests. More people are being diagnosed with low-risk thyroid cancer, but the use of imaging among these patients has skyrocketed disproportionately. Thyroid cancer generally has a high survival rate -- roughly 96 percent of patients are alive 10 years later. But a small number of thyroid cancers are more aggressive and likely to return.

To protect yourself from malaria sleep with a chicken next to your bed

Thu, 21/07/2016 - 1:51am
For the first time, scientists have shown that malaria-transmitting mosquitoes actively avoid feeding on certain animal species such as chickens, using their sense of smell. Odors emitted by species such as chickens could provide protection for humans at risk of mosquito-transmitted diseases, according to a study.

Putting the sloth in sloths: Arboreal lifestyle drives slow motion pace

Wed, 20/07/2016 - 9:04pm
Scientists set out to measure the energetics of wild two- and three-toed sloths at a field site in in northeastern Costa Rica. The purpose of the study was to help explain why arboreal folivores are indeed so rare and why more animals have not evolved to take advantage of a widespread ecological niche.

Groundwater discharge to upper Colorado River Basin varies in response to drought

Wed, 20/07/2016 - 8:48pm
Groundwater discharge that flows into the Upper Colorado River Basin varies in response to drought, which is likely due to aquifer systems that contain relatively young groundwater, according to a new study.

Potential drug candidates could intervene in deadly diseases

Wed, 20/07/2016 - 8:48pm
Scientists have identified drug candidates that can boost a cell's ability to catch the 'typos' in protein production that can cause a deadly disease called amyloidosis, revealing a new approach to intervene in human disease.

3-D-printing lab instruments one block at a time

Wed, 20/07/2016 - 6:35pm
Building lab instruments for chemistry and biology experiments used to be an expensive, time consuming process only done by scientists with specialized training. A 3-D printed, Lego-like system of blocks is changing that. In addition to real research applications, the system can also be used for STEM education, where students gain both an engineering experience by building the instruments and a science experience as they use them.

Scientists apply new imaging tool to common brain disorders

Wed, 20/07/2016 - 6:35pm
A new approach has been developed to scanning the brain for changes in synapses that are associated with common brain disorders. The technique may provide insights into the diagnosis and treatment of a broad range of disorders, including epilepsy and Alzheimer's disease, say authors of a new report.
