Scientists find surprising way to affect information storage properties in metal alloy.
By studying how electrons in two-dimensional graphene can literally act like a liquid, researchers have paved the way for further research into a material that has the potential to enable future electronic computing devices that outpace silicon transistors.
NASA and SpaceX remained tight-lipped Thursday about what caused a mysterious but apparently serious incident last weekend during engine tests on the Crew Dragon capsule designed to carry US astronauts to the International Space Station (ISS) later this year.
Researchers at DOE's Lawrence Berkeley National Laboratory (Berkeley Lab) have 3-D-printed an all-liquid device that, with the click of a button, can be repeatedly reconfigured on demand to serve a wide range of applications—from making battery materials to screening drug candidates.
Bacterial cells use both a virus—traditionally thought to be an enemy—and a prehistoric viral protein to kill other bacteria that competes with it for food according to an international team of researchers who believe this has potential implications for future infectious disease treatment.
Biologists at Tufts University have developed a computational model of planarian (flatworm) regeneration that explains how fragments of planaria determine which end should form a tail and which should form a head. The development begins to answer an important question in regeneration research—what are the signals that determine the rebuilding of specific anatomical structures? Combining modeling and experiment, the researchers determined that the direction of nerve fibers sets the redistribution of chemical signals establishing the direction of the head-to-tail axis. The model was also able to predict the outcomes of numerous genetic, pharmacological, and surgical manipulations, such as worms with two heads or two tails.
The longevity of Earth's continents in the face of destructive tectonic activity is an essential geologic backdrop for the emergence of life on our planet. This stability depends on the underlying mantle attached to the landmasses. New research by a group of geoscientists from Carnegie, the Gemological Institute of America, and the University of Alberta demonstrates that diamonds can be used to reveal how a buoyant section of mantle beneath some of the continents became thick enough to provide long-term stability.
