Adapting magnetometers for noisy, physically demanding environments
Researchers routinely measure magnetic fields to better understand a vast array of natural phenomena including geological movements, solar flares, neuronal communication in the brain, and molecular-scale chemical processes. …
A three-dimensional view of the Milky Way
In our Milky Way, there are about 200 billion suns as well as large quantities of gas, some of which serves as raw material for star births. The gas collects in compact lumps but also appears as extended molecular clouds. Astronomers have used the Apex sub-millimeter telescope in Chile to look deep into the galactic plane and measure the interstellar medium….
In a Major Scientific Breakthrough, AI Predicts the Exact Shape of Proteins
Researchers have made a major breakthrough using artificial intelligence that could revolutionize the hunt for new medicines. The scientists have created A.I. software that uses a protein’s DNA sequence to predict its three-dimensional structure to within an atomâ(TM)s width of accuracy. weiserfireman shares a report: The achievement, which solves a 50-year-old challenge in molecular biology, was accomplished by a team from…

Surfaces help quantum switches
The quantum dynamics of hydrogen are central to many problems in nature, being strongly influenced by the environment in which a reaction takes place. In their contribution to PRL, members of the Lise Meitner Group at the MPSD address hydrogen transfer within a supported molecular switch, showing that the surface support can play a decisive role in the tunneling reaction. …

Researcher sets record for quantum chemistry calculation
A researcher from The Australian National University (ANU) has used one of the most powerful supercomputers in the world to predict the quantum mechanical properties of large molecular systems with an accuracy that surpasses all previous experiments. …
Tiny Variants In Genes May Dictate Severity of Coronavirus
Scientists are tracking small differences in DNA to explain why the disease has different effects. An anonymous reader shares a report from The Guardian: Key developments include research which indicates that interferon — a molecular messenger that stimulates immune defenses against invading viruses — may play a vital role in defending the body. Scientists have found that rare mutations in some…
