University of Delaware researcher Mark Moline recently co-authored a paper in Robotics on the advantage of linking multi-sensor systems aboard autonomous underwater vehicles to enable the vehicle to synthesize data in real-time so it can independently make decisions about what action to take next.
APEX, the Atacama Pathfinder EXperiment telescope, is located at 5100 metres above sea level on the Chajnantor Plateau in Chile's Atacama region. The ATLASGAL survey took advantage of the unique characteristics of the telescope to provide a detailed view of the distribution of cold dense gas along the plane of the Milky Way galaxy. The new image includes most of the regions of star formation in the southern Milky Way.
Studying mice, new research shows that a natural sugar called trehalose prevents the sugar fructose — thought to be a major contributor to nonalcoholic fatty liver disease — from entering the liver and triggers a cellular housekeeping process that cleans up excess fat buildup inside liver cells.
X-ray scans reveal that dodo's relative brain size was similar to pigeons, likely had enhanced sense of smell.
A team of national laboratory and university researchers led by the Department of Energy’s (DOE’s) Argonne National Laboratory is growing large test plots of switchgrass crops with the farmer in mind. For the first time, researchers have mixed different genetic varieties of switchgrass on production-size plots, hypothesizing this could increase yield by extending the growing season, varying the size of the switchgrass plants to produce a fuller crop and potentially reducing the crop’s vulnerability to weather fluctuations. A seven-year study showed the switchgrass variety mixture was, most consistently, the highest yielding crop, as measured by the harvested dry weight from each plot.
Worldwide, an estimated 25 percent of children under age 5 suffer from stunted growth and development. A team of researchers has found that inadequate dietary intake of essential amino acids and the nutrient choline is linked to stunting.
Employing cutting edge bioinformatics & next generation sequencing techniques, scientists have reconstructed the spider ‘tree of life’ to come to intriguing new conclusions about the evolution of the web, something which has important implications for the overall story of spider evolution.
The types of beneficial fungi that associate with tree roots can alter the fate of a patch of tropical forest, boosting plant diversity or, conversely, giving one tree species a distinct advantage over many others, researchers report.
Sharks have a reputation for having voracious appetites, but a new study shows that most coral reef sharks eat prey that are smaller than a cheeseburger.
Ever since it was realized that asteroid and comet impacts are a real and present danger to the survival of life on Earth, it was thought that most of those objects end their existence in a dramatic final plunge into the Sun. A new study published on Thursday in the journal Nature finds instead that most of those objects are destroyed in a drawn out, long hot fizzle, much farther from the Sun than previously thought. This surprising new discovery explains several puzzling observations that have been reported in recent years.
Researchers at Washington University School of Medicine in St. Louis have found that in patients with obesity, the greatest improvements to health come from losing just 5 percent of their body weight. That relatively small weight loss lowered patients’ risk for diabetes and cardiovascular disease and improved metabolic function in liver, fat and muscle tissue.
Between 1947 and 1956, John Curtis and his colleagues and students conducted their prairie relic study, surveying more than 200 undisturbed prairie remnants in Wisconsin. Today [Feb. 19, 2016] UW-Madison graduate student Amy Alstad and a team of researchers have published a third survey based on Curtis’ legacy work. They found that human influence has accelerated the rate of species change in these prairies.
Laboratory rats who breathed Beijing's highly polluted air gained weight and experienced cardio-respiratory and metabolic dysfunctions after three to eight weeks of exposure.
Astronomers using NASA's Hubble Space Telescope have measured the rotation rate of 'super-Jupiter-class' exoplanet 2M1207b by observing the varied brightness in its atmosphere. This is the first rotation rate measurement of a massive exoplanet using direct imaging. The observations also confirm that the planet's atmosphere has layers of patchy, colorless clouds.
In the largest study of its kind, an international team of experts led by Newcastle University, UK, has shown that both organic milk and meat contain around 50% more beneficial omega-3 fatty acids than conventionally produced products.
New research explores the impact of hunter-gatherers on north Pacific marine food webs and the behaviors that helped preserve their network of food sources. The findings hold implications for modern food webs.
DNA results show that shelter workers are often mistaken when they label a dog as a pit bull, with potentially devastating consequences for the dogs, a new University of Florida study has found.
The organs in our body may have a sexual identity of their own, new research suggests.
A qualitative study finds that most people who have lost a lot of weight don’t perceive themselves as being “judged” because they used to be overweight or obese – which contradicts earlier research that people were still stigmatized even after reaching a healthy weight.
Swimmers and divers who are prone to a sudden and potentially life-threatening form of pulmonary edema in cold water could benefit from a simple and readily available dose of sildenafil, according to findings from a small study by Duke Health researchers.
In one of the first reproductive studies to focus on young men and fatherhood, researchers at Northwestern Medicine found that an adolescent male’s attitude toward risky sex, pregnancy and birth control can predict whether or not he will end up living with his future offspring.
Two new Cornell University studies show how diverse marine organisms are susceptible to diseases made worse by warming oceans. The first study warns that warm sea temperatures in 2015 may increase the levels of epizootic shell disease in American lobster in the northern Gulf of Maine in 2016. The second provides the first evidence linking warmer ocean temperatures with a West Coast epidemic of sea star wasting disease that has infected more than 20 species and devastated populations since 2013.
UW astronomers Breanna Binder and Ben Williams have identified a rare type of 'supernova impostor' in a nearby galaxy, with implications for how scientists look at the short, complex lives of massive stars.

The ocean’s power to rein in carbon and protect the environment is vast but not well-understood. But now, an international team of scientists has begun to illuminate how the ocean plucks carbon from the atmosphere, where it contributes to global warming, and shuttles it to the bottom of the sea.
The whooping crane, with its snowy white plumage and trumpeting call, is one of the most beloved American birds, and one of the most endangered. As captive-raised cranes are re-introduced in Louisiana, they are gaining a new descriptor: natural killer. A new study from the University of Tennessee, Knoxville, suggests Louisiana cranes are faring well thanks in part to their penchant for hunting reptiles and amphibians.

A hormone implicated in monogamy and aggression in animals also promotes trust and cooperation in humans in risky situations, Caltech researchers say.
Children play an important role in ensuring that they are cared for by adults by using physical and cognitive cues. But what’s more important in how they influence adults and elicit their nurturing spirit? Is it their physical features or what they say?
Using a model blood vessel system built on a polymer microchip, researchers have shown that the relative softness of white blood cells determines whether they remain in a dormant state along vessel walls or enter blood circulation to fight infection.
An international team of scientists have discovered two new plankton-eating fossil fish species of the genus called Rhinconichthys from the oceans of the Cretaceous Period, about 92 million years ago, when dinosaurs roamed the planet.
Research published in 2012 garnered international attention by suggesting that a possible early human ancestor had lived on a diverse woodland diet including hard foods mixed in with tree bark, fruit, leaves and other plant products. But new research by an international team of researchers now shows that Australopithecus sediba didn’t have the jaw and tooth structure necessary to exist on a steady diet of hard foods.
By chance, scientists have discovered a malaria parasite that infects white-tailed deer. It’s the first-ever malaria parasite known to live in a deer species and the only native malaria parasite found in any mammal in North or South America.
