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.
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.
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.
A team of UWM physicists image a never-before-seen molecular reaction as a light-sensitive protein responds to light. The work, using an X-ray laser, is unmasking how proteins carry out the chemistry necessary for life.
A team of researchers who two years ago announced a 'Trojan horse' method of entering a cell without harming it have now found, in effect, the lock to the cellular 'trap door.'
Spinal muscular atrophy (SMA) is a disease that causes progressive degeneration in the nerve cells that control muscles, thereby causing muscle weakness and eventually death. SMA affects approximately 200,000 people in the US, often children. Now, researchers at the University of Missouri are studying a subtype of SMA, spinal muscular atrophy with respiratory distress type 1 (SMARD1), and have developed a gene replacement therapy that can be used to treat and control the disease in the future.
A tension-sensitive 'fail safe' protein helps make sure that when our cells divide the two resulting cells inherit the normal number of chromosomes. Chromosome separation errors, leading to too few or too many chromosomes, is the most common genetic abnormality in cancer cells. This latest finding in cell division biology may guide the development of new chemotherapeutic drugs that target the machinery of cell division.
Using ALMA, a team of astronomers has delved remarkably deep into the heart of a nearby elliptical galaxy to study the motion of a disk of cold interstellar gas encircling the supermassive black hole at its center, providing one of the most accurate mass measurements to date for a black hole outside of our Galaxy.
Scientists have tracked the reaction of a protein responding to light, paving the way for a new understanding of life's essential reactions.
