Discord"s latest update broke it on macOS -- here"s how to fix it
A new update has broken Discord for some owners of Apple Silicon Macs — but there's a fix.If you updated Discord on your Apple silicon-based Mac on Thursday, you probably wound up with a program that no longer opens. Even after restarting and reins.....»»
New research into pangolin genomics may aid in conservation efforts
A new paper in Molecular Biology and Evolution provides, for the first time, a comprehensive set of genomic resources for pangolins (sometimes known as scaly anteaters) that researchers believe will be integral for protecting these threatened mammals.....»»
How proteins roll the dice to determine bee sex
To date it has been unclear exactly how the sex of a bee is determined. A research team from Heinrich Heine University Düsseldorf (HHU) including biologists and chemists has now identified a key gene and the molecular mechanism linked with it. In th.....»»
Molecular knots, left and right: How molecules form knots
Helical molecules, similarly to a corkscrew, have a spiral shape that can be either left- or right-turning. Such "chiral molecules" can collectively organize (assemble) into large left- or right-handed twisted structures. These exhibit special optica.....»»
Electronic sensor the size of a single molecule a potential game-changer
Australian researchers have developed a molecular-sized, more efficient version of a widely used electronic sensor, in a breakthrough that could bring widespread benefits......»»
Simulations reveal the atomic-scale story of qubits
Researchers led by Giulia Galli at University of Chicago's Pritzker School of Molecular Engineering report a computational study that predicts the conditions to create specific spin defects in silicon carbide. Their findings, published online in Natu.....»»
Scientists observe interaction of components in tire rubber at the atomic scale
Scientists have observed the molecular motion of rubber components typically used in automobile tires—polybutadiene and carbon black—with the world's fastest time resolution......»»
Concave, umbrella-like metal complexes provide space for giant molecular rotors to operate in solid state
Solid materials are generally known to be rigid and unmoving, but scientists are turning this idea on its head by exploring ways to incorporate moving parts into solids. This can enable the development of exotic new materials such as amphidynamic cry.....»»
Elk hoof disease likely causes systemic changes
Elk treponeme-associated hoof disease, previously thought to be limited to deformations in elks' hooves, appears to create molecular changes throughout the animal's system, according to epigenetic research from Washington State University......»»
