New galaxy sheds light on how stars form
A lot is known about galaxies. We know, for instance, that the stars within them are shaped from a blend of old star dust and molecules suspended in gas. What remains a mystery, however, is the process that leads to these simple elements being pulled together to form a new star. Source: https://phys.org/news/2021-01-galaxy-stars.html…
Why Cancer Cells Waste So Much Energy
MIT News: In the 1920s, German chemist Otto Warburg discovered that cancer cells don’t metabolize sugar the same way that healthy cells usually do. Since then, scientists have tried to figure out why cancer cells use this alternative pathway, which is much less efficient. MIT biologists have now found a possible answer to this longstanding question. In a study appearing in…
Scientists Observe Live Cells Responding To Magnetic Fields For First Time
An anonymous reader quotes a report from New Atlas: One of the most remarkable “sixth” senses in the animal kingdom is magnetoreception — the ability to detect magnetic fields — but exactly how it works remains a mystery. Now, researchers in Japan may have found a crucial piece of the puzzle, making the first observations of live, unaltered cells responding to…
How chaos and tendency to reach thermal equilibrium arise from fundamental laws of physics
Normally the word “chaos” evokes a lack of order: a hectic day, a teenager’s bedroom, tax season. And the physical understanding of chaos is not far off. It’s something that is extremely difficult to predict, like the weather. Chaos allows a small blip (the flutter of a butterfly wing) to grow into a big consequence (a typhoon halfway across the world),…
Liquid Glass Discovered As New State of Matter
An anonymous reader quotes a report from New Atlas: Mundane as it may seem, glass is a surprisingly mysterious material. Now scientists at the University of Konstanz have identified a new state of matter called liquid glass, which has some unusual properties. […] In the new study, the researchers discovered a form of glass where the atoms exhibit a complex behavior…
AI Solves Schrodinger’s Equation
An anonymous reader quotes a report from Phys.Org: A team of scientists at Freie Universitat Berlin has developed an artificial intelligence (AI) method for calculating the ground state of the Schrodinger equation in quantum chemistry. The goal of quantum chemistry is to predict chemical and physical properties of molecules based solely on the arrangement of their atoms in space, avoiding the…
Artificial intelligence solves Schrödinger’s equation
A team of scientists at Freie Universität Berlin has developed an artificial intelligence (AI) method for calculating the ground state of the Schrödinger equation in quantum chemistry. The goal of quantum chemistry is to predict chemical and physical properties of molecules based solely on the arrangement of their atoms in space, avoiding the need for resource-intensive and time-consuming laboratory experiments. In…
Accurate theoretical modeling unravels changes in molecules interacting with quantum light
A team of researchers from Italy, Norway, and Germany has demonstrated that the properties of molecules undergo significant changes when interacting with quantized electromagnetic fields in optical cavities. Using novel theoretical methodologies and computational simulations, the team revealed that the ground- and excited-state chemistry of molecules can be modified by a confinement in space. They show how the transfer of electrons…
