New research reveals Neem-based drugs may help fight future coronavirus variants. Extract from the bark of the Neem tree may help treat and reduce the spread of coronavirus, according to a new study led by scientists at the University of Colorado Anschutz Medical Campus and the Indian Institute of Science Education and Research Kolkata.

The study, reported recently in the journal Virology, shows that components of Neem bark may target a wide range of viral proteins, suggesting its potential as an antiviral agent against emerging variants of coronaviruses (including SARS-CoV-2).

The Neem tree, indigenous to India, has been used for thousands of years for its anti-parasitic, anti-bacterial and antiviral properties...

Physicists at UC Santa Barbara have become the first to experimentally observe a quirky behavior of the quantum world: a “quantum boomerang” effect that occurs when particles in a disordered system are kicked out of their locations. Instead of landing elsewhere as one might expect, they turn around and come back to where they started and stop there.

“It’s really a fundamentally quantum mechanical effect,” said atomic physicist David Weld, whose lab produced the effect and documented it in a paper published in Physical Review X. “There’s no classical explanation for this phenomenon.”

Researchers from the University of Turku, Finland, found that the axis of rotation of a black hole in a binary system is tilted more than 40 degrees relative to the axis of stellar orbit. The finding challenges current theoretical models of black hole formation.

The observation by the researchers from Tuorla Observatory in Finland is the first reliable measurement that shows a large difference between the axis of rotation of a black hole and the axis of a binary system orbit. The difference between the axes measured by the researchers in a binary star system called MAXI J1820+070 was more than 40 degrees.

Often for the space systems with smaller objects orbiting around the central massive body, the own rotation axis of this body is to a high degree aligned with the rotation axis...
