A team led by the Department of Energy's Oak Ridge National Laboratory used state-of-the-art microscopy to identify a previously undetected feature, about 5 billionths of a meter (nanometers) wide, in a solid electrolyte. The work experimentally verifies the importance of that feature to fast ion transport, and corroborates the observations with theory. The new mechanism the researchers report in Advanced Energy Materials points out a new strategy for the design of highly conductive solid electrolytes.
A recent Vermont study may be the first nationwide to calculate the differences in infant hospital costs based on the number of embryos transferred at one time via in vitro fertilization.
Diamonds are one of the most coveted gemstones. But while some may want the perfect diamond for its sparkle, physicists covet the right diamonds to perfect their experiments. The gem is a key component in a novel system that enables precision measurements that could lead to the discovery of new physics in the sub-atomic realm -- the domain of the particles and forces that build the nucleus of the atom.
Chemists provide the first direct evidence that a T cell gives precise mechanical tugs to other cells, and demonstrate that these tugs are central to a T cell's process of deciding whether to mount an immune response.
A team of scientists have discovered a key mechanism that drives a bacteria that kills male insects, a development that could potentially be exploited to control insect pest species in the future.
Using rocks extracted from a soil trench, scientists have reconstructed a climate record for western North America.
NASA-NOAA's Suomi National Polar-orbiting Partnership satellite (S-NPP) carries an instrument so sensitive to low light levels that it can detect wildfires in the middle of the night as well as during the daytime.
In a dramatic show of physician support for deeper health reform -- and for making a decisive break with the private insurance model of financing medical care -- 2,231 physicians are calling for a publicly financed, single-payer national health program that would cover all Americans for all medically necessary care. The proposal, drafted by a panel of 39 leading physicians, is linked to an editorial titled 'Moving Forward from the Affordable Care Act to a Single-Payer System.'
Four new studies surrounding the effects of mango consumption suggest this superfruit has the potential to help combat adverse effects associated with high fat diets and obesity (animal study), as well inhibit growth of fat cells (anti-lipogenic properties in an in-vivo study), slow advancement of breast cancer tumors (animal study), as well as improve regularity and decrease inflammation associated with constipation (human subject study). The research was presented at the 2016 Experimental Biology conference in San Diego.
Ever since the advent of smartwatches, technologists have been looking to expand interactions beyond the confines of the small watch face. A new wearable technology developed at Carnegie Mellon University suggests turning the entire lower arm into a touchpad. Called SkinTrack and developed by the Human-Computer Interaction Institute's Future Interfaces Group, the new system allows for continuous touch tracking on the hands and arms.
