New research has found lower bone density in adults who are likely to have undiagnosed celiac disease, an autoimmune disease triggered by consuming gluten, despite this group consuming more calcium and phosphorous than the control group.
Read moreEngineers have found a way to significantly speed up the planning process required for a robot to adjust its grasp on an object by pushing that object against a stationary surface. Whereas traditional algorithms would require tens of minutes for planning out a sequence of motions, the new team's approach shaves this planning process down to less than a second.
Read moreResearchers studied fossilized Moroccan Ampyx trilobites, which lived 480 million years ago and showed that the trilobites had probably been buried in their positions — all oriented in the same direction. Scientists deduced that these Ampyx processions may illustrate a kind of collective behavior adopted in response to cyclic environmental disturbances.
Read moreResearchers have demonstrated bio-inspired devices that accelerate routes to neuromorphic, or brain-like, computing. Their discovery could support the emergence of computing networks modeled on biology for a sensory approach to machine learning.
Read moreIn order to make transistors that operate using the spin of electrons, rather than their charge, it is necessary to find a way of switching spin currents on and off. Furthermore, the lifetime of the spins should at least be equal to the time taken for these electrons to travel through a circuit. Scientists have now taken an important step forward by creating a device that meets both of these requirements.
Read more'Weather' in clusters of galaxies may explain a longstanding puzzle. Scientists have now used sophisticated simulations to show how powerful jets from supermassive black holes are disrupted by the motion of hot gas and galaxies, preventing gas from cooling, which could otherwise form stars.
Read moreSolutions found in nature should be our first line of defense against the increasing number of climate change-related natural disasters, say experts.
Read moreA recent study helps to better explain the processes in the Earth's interior beneath the Yellowstone supervolcano.
Read morePhysicists have developed a fast and sensitive mechanical tool to measure light. The graphene nanomechanical bolometer is the fastest and most sensitive in its class. It is poised to detect nearly every color of light at high speeds and obtain measurements at and far above room-temperature.
Read moreMany commercial films worldwide continue to express womanhood in a stereotypical manner, a recent study using image analysis showed. A research team developed a novel image analysis method for automatically quantifying the degree of gender bias in in films.
