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.
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.
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).
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.
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 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 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.
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.
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.
Hormone therapy has a negligible effect on verbal memory and other mental skills regardless of how soon after menopause a woman begins therapy, new research shows.
Screening for suicide risk among publicly insured urban children who are experiencing psychological distress is vitally important, finds a new study.
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 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.
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.
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.
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.
A new species of megaraptorid dinosaur discovered in Patagonia may help discern the evolutionary origins of the megaraptorid clade.
Little auks forage in the same areas off East Greenland -- the continental shelf and its edge -- regardless of whether sea ice is present or absent, according to a new study.
Routine scientific procedures using millions of animals are still being authorized when there is a tried and tested alternative, according to a group of scientists investigating the production of antibodies.
Research comparing pastures with multiple types of plants to those with less variety shows surprising results in land productivity and soil health.
