Quantum-centric supercomputing simulates 12,635-atom protein

The scale of chemistry simulations with quantum computing has increased dramatically in just the last few months. In the latest milestone for the field, researchers from Cleveland Clinic, RIKEN, and IBM used a quantum-centric supercomputing (QCSC) framework to calculate the electronic structure of a pair of large protein-ligand complexes, reaching a scale of 12,635 atoms in the largest simulation.

Brutal field trip provides new insights into Arctic winter

It was the hardest field trip they had ever been on, but the result was both surprising and exciting. After hiking 9 kilometers with a 400-meter elevation gain and carrying heavy backpacks through very rocky terrain, the researchers spent more than 24 hours in the field and returned with sediment samples from the lake Stuptjørna.

New form of NAND flash data storage for deep space missions can survive 1 million rads

As space missions travel farther from Earth, spacecraft must increasingly be able to process and store their own data. Soon, artificial intelligence (AI) could be the primary tool for handling this growing volume of information.

Climate catch-22: Cleaning up air pollution could speed key Atlantic current decline

It may sound counterintuitive, but new research suggests that cleaning up air pollution could contribute to a weakening of the Atlantic Meridional Overturning Circulation (AMOC). This is the ocean current system that acts like a giant conveyor belt, moving warm surface water northward and cool deep water southward.

Overlooked 'history force' may skew particle motion by up to 60% in shaken fluids

Physicists at the University of Bayreuth have investigated the so-called Basset–Boussinesq history force acting on particles in fluids. Due to the difficulty of calculating it, this force is often neglected—a fact that Bayreuth doctoral researcher Frederik Gareis already identified as a secondary school pupil during a student research project with his supervisor. The researchers report their new findings on the history force in Physical Review Fluids.
