Cosmic History can explain the Properties of Mercury, Venus, Earth and Mars

This is the sharpest image ever taken by ALMA — sharper than is routinely achieved in visible light with the NASA/ESA Hubble Space Telescope. It shows the protoplanetary disc surrounding the young star HL Tauri. These new ALMA observations reveal substructures within the disc that have never been seen before and even show the possible positions of planets forming in the dark patches within the system.

Astronomers have managed to link the properties of the inner planets of our solar system with our cosmic history: with the emergence of ring structures in the swirling disk of gas and dust in which these planets were formed...

Scientists identify Antibodies that can Neutralize Omicron

COVID-19 virus SARS-COV-2 OMICRON strain, covid-19 South African variant B.1.1.529 omicron 3d rendering

An international team of scientists have identified antibodies that neutralize omicron and other SARS-CoV-2 variants. These antibodies target areas of the virus spike protein that remain essentially unchanged as the viruses mutate.

By identifying the targets of these “broadly neutralizing” antibodies on the spike protein, it might be possible to design vaccines and antibody treatments that will be effective against not only the omicron variant but other variants that may emerge in the future, said David Veesler, investigator with the Howard Hughes Medical Institute and associate professor of biochemistry at the University of Washington School of Medicine in Seattle...

New Data-Decoding approach could lead to Faster, Smaller Digital Tech

Evgeny Tsymbal “holds” a rendering of the atomic structure found in ruthenium oxide, a material whose properties could point the way to faster digital devices packed with more memory.

Most scientists would blanch at being labeled a spin doctor. But when it comes to Evgeny Tsymbal, Ding-Fu Shao and their colleagues, the lab coat fits.

The University of Nebraska–Lincoln physicists have charged to the forefront of spintronics, a next-gen class of data storage and processing poised to complement the digital electronics that have ruled the realm of high tech for decades.

Ahead of that future, though, loom nanoscale obstacles whose size belies their difficulty...

Drunken Solution to the Chaotic Three-Body problem

The three-body problem is one of the oldest problems in physics: It concerns the motions of systems of three bodies—like the sun, Earth, and the moon—and how their orbits change and evolve due to their mutual gravity. The three-body problem has been a focus of scientific inquiry ever since Newton.

When one massive object comes close to another, their relative motion follows a trajectory dictated by their mutual gravitational attraction, but as they move along and change their positions along their trajectories, the forces between them, which depend on their mutual positions, also change, which, in turn, affects their trajectory. For two bodies (e.g...
