Scientists from Russia, Germany, and Venezuela investigated the evolution of the 2-D semiconductor GaSe exposed to air. They revealed that GaSe properties could be exploited in nanoelectronics when manufactured in a vacuum or inert atmosphere. This research opens up new prospects for the technological application of this promising 2-D material.
While football-related concussions have been top of mind in recent years, people have struggled to create technology to accurately measure them in real time. BYU mechanical engineering Ph.D. student Jake Merrell and a team of researchers across three BYU departments have developed and tested a nano composite smartfoam that can be placed inside a football helmet (and pads) to more accurately test the impact and power of hits.
McGill University researchers have discovered a mechanism through which mitochondria, the energy factory of our body's cells, play a role in preventing cells from dying when the cells are deprived of nutrients - a finding that points to a potential target for next-generation cancer drugs.
In a major step forward, scientists at CSHLtoday publish a discovery about the molecular-genetic basis of neuronal cell types. Neurons are the basic building blocks that wire up brain circuits supporting mental activities and behavior. The study, which involves sophisticated computational analysis of the messages transcribed from genes that are active in a neuron, points to patterns of cell-to-cell communication as the core feature that makes possible rigorous distinctions among neuron types across the mouse brain.
Most efforts to control ice build-up on structures like wind turbines and solar cells involve creating a surface that repels water. But Norwegian researchers have engineered a different approach that allows ice to form on a surface, but then causes it to crack off.
We must move faster towards a low-carbon world if we are to limit global warming to 2 degrees C this century, experts have warned.
Are quantum states real? This most fundamental question in quantum mechanics has not yet been satisfactorily resolved, although its realistic interpretation seems to have been rejected by various delayed-choice experiments. Recently, scientists from University of Science and Technology of China, Harbin University of Science and Technology and other collaborators propose and demonstrate a quantum twisted double-slit experiment, in which the physical reality of wavefunctions is confirmed for the first time.
The materiality exhibited by manmade polymers currently relies on simple chemical bonds and the sequence order taken by molecules in the polymer chain. We now no longer need to rely on fate to determine such materiality with this new technique for precisely defining polymer-chain order. This system uses highly specific 'grabber' ends on each molecule that bond with only one type of 'pin' end on another molecule.
A new imaging technique makes it possible to precisely digitize clear objects and their surroundings, an achievement that has eluded current state-of-the-art 3-D rendering methods.
Researchers are now equipped with additional insight into how poisonous frogs may have evolved resistance against their own toxins, thanks to the results of a new study.
