First results from LUX dark matter detector: Searching for elusive dark matter

In its first three months of operation, the Large Underground Xenon (LUX) experiment has proven itself to be the most sensitive dark matter detector in the world, scientists with the experiment have announced. Researchers are now preparing the detector, located a mile underground in an old South Dakota gold mine, for a 300-day run next year in hopes of detecting for the first time weakly...

Pain in infancy alters response to stress, anxiety later in life

Early life pain alters neural circuits in the brain that regulate stress, suggesting pain experienced by infants who often do not receive analgesics while undergoing tests and treatment in neonatal intensive care may permanently alter future responses to anxiety, stress and pain in adulthood, medical researchers have...

New concept needed for a better understanding of biodiversity in time, space

By now, biodiversity is a well known term even in the broader public, as it is used in many media reports about species extinction, natural resources or climate change. Yet research in this field is still lacking an integrative approach. Paleontologists and biologists, for example, still cut their own path, their studies in species diversity and species extinction are rarely...

Bottom-feeding behavior of humpback whales confirmed

Scientists have confirmed that humpback whales in the southern Gulf of Maine are spending more feeding time on the ocean floor than in any of their known feeding behaviors, putting them at risk for entanglement in bottom-set fishing gear like lobster traps.

Nerve stimulation in neck may reduce heart failure symptoms

A multidisciplinary team of experts in heart failure, cardiac arrhythmia, and neurosurgery are now testing nerve stimulation in the neck as a novel therapy for heart failure patients to potentially help relieve their debilitating symptoms of fatigue, shortness of breath, and heart arrhythmias, while reducing their...

Bloomberg's health legacy: Urban innovator or meddling nanny?

As New York City Mayor Michael Bloomberg prepares to leave office, a commentary by a leading bioethicist analyzes his controversial public health policies and concludes that he is an urban innovator who created a new paradigm of public health, "reaching beyond infectious diseases to upstream risk factors in everyday life and the human...

Media Consumption To Average 15.5 Hours A Day By 2015

A new report looks at media consumption by individuals in and out of the home, excluding the workplace, between 2008 and 2015, breaking “media” down into 30 categories of media type and delivery (e.g. television, social media, computer gaming) and conclude that the average person will consume 15.5 hours per day by...

Baking blueberries changes their polyphenol content, health benefits

Blueberries are called a "superfood" for their high polyphenol content, but when served as warm, gooey pie filling or when lending bursts of sweet flavor to a muffin, their "super" health benefits change. Scientists studied how cooking and baking affect the increasingly popular fruit's polyphenols and reported their mixed findings in a new...

Recycling valuable materials used in TVs, car batteries, cell phones

Many of today's technologies, from hybrid car batteries to flat-screen televisions, rely on materials known as rare earth elements (REEs) that are in short supply, but scientists are reporting development of a new method to recycle them from wastewater. The process could help alleviate economic and environmental pressures facing the REE...

Gimball: A crash-happy flying robot

Gimball bumps into and ricochets off of obstacles, rather than avoiding them. This 34-cm in diameter spherical flying robot buzzes around the most unpredictable, chaotic environments, without the need for fragile detection sensors.

Brain regions can be specifically trained with video games

Video gaming causes increases in the brain regions responsible for spatial orientation, memory formation and strategic planning as well as fine motor skills. This has been shown in a new study. The positive effects of video gaming may also prove relevant in therapeutic interventions targeting psychiatric...
