Researchers observe how the flexibility of a protein hinge is crucial to the transfer of cell proteins
Ubiquitination—the addition of the protein ubiquitin—is a key stage in many cell processes, such as protein degradation, DNA repairs, and signal transduction. Using high-speed atomic force microscopy (HS-AFM) and molecular modeling, researchers l.....»»
Unveiling sodium channel dynamics: New insights into cell biology using high-speed atomic force microscopy
The transport of ions to and from a cell is controlled by pore-forming proteins embedded in the cell membrane. In particular, voltage-gated sodium channels (VGSCs) govern the transfer of sodium (Na+) ions, and play an important role in the regulation.....»»
Discovery of low-lying isomeric states in cesium-136 has applications in particle astrophysics
Large, low-background detectors using xenon as a target medium are widely used in fundamental physics, particularly in experiments searching for dark matter or studying rare decays of atomic nuclei. In these detectors, the weak interaction of a neutr.....»»

HomeKit Weekly: Yeelight Cube Clock Kit lets you build your own retro display with Matter support
I have become a massive fan of all things retro in recent years. I love the Tidbyt clock. I am ready for Apple to bring the iPod back. Old stuff is back. I’ve recently been testing a really fun Tidbyt alternative with HomeKit support. It doesn’t.....»»
A dense quark liquid is distinct from a dense nucleon liquid
Atomic nuclei are made of nucleons (like protons and neutrons), which themselves are made of quarks. When crushed at high densities, nuclei dissolve into a liquid of nucleons and, at even higher densities, the nucleons themselves dissolve into a quar.....»»
Ancient stars could make elements with atomic masses greater than 260
The first stars of the universe were monstrous beasts. Comprised only of hydrogen and helium, they could be 300 times more massive than the sun. Within them, the first of the heavier elements were formed, then cast off into the cosmos at the end of t.....»»
Can seabirds hear their way across the ocean? Our research suggests so
Animals cover astonishing distances when they are looking for food. While caribou, reindeer and wolves clock up impressive mileage on land, seabirds are unrivaled in their traveling distances. Arctic terns travel from the Arctic to Antarctica and bac.....»»
