Could the Asteroid Ryugu be a Remnant of an Extinct Comet? Scientists now answer

Asteroids hold many clues about the formation and evolution of planets and their satellites. Understanding their history can, therefore, reveal much about our solar system. While observations made from a distance using electromagnetic waves and telescopes are useful, analyzing samples retrieved from asteroids can yield much more detail about their characteristics and how they may have formed. An endeavor in this direction was the Hayabusa mission, which, in 2010, returned to Earth after 7 years with samples from the asteroid Itokawa.

The successor to this mission, called Hayabusa2, was completed near the end of 2020, bringing back material from Asteroid 162173 “Ryugu,” along with a collection of images and data gathered remotely from close proximity...

The SARS-CoV-2 virus that causes COVID-19 has killed 6 million people worldwide since 2019.

Researchers now have discovered a monoclonal antibody that potentially acts as a potent universal coronavirus therapy against the COVID-19 virus and all its variants of concern, including delta and omicron. It also shows effectiveness against the deadly coronaviruses SARS, the Severe Acute Respiratory Syndrome that emerged in China in 2002, and MERS, the Middle East Respiratory Syndrome that appeared in Saudi Arabia in 2012. It even shows effectiveness against several common cold coronaviruses.

This universal activity results from the monoclonal antibody targeting a region of the viral spike protein that is highly conserved among beta-coronaviruses, yet i...

Quantum Technology could make Charging Electric Cars as Fast as Pumping Gas

A pictorial illustration of today’s electric vehicle versus the future vehicle based on quantum battery technologies. Employing quantum charging would lead to a 200 times speedup in a typical EV, which means that the charging time would be cut from 10 hours to about 3 minutes (at home), or 30 minutes to 9 seconds at a charging station.

Whether it’s photovoltaics or fusion, sooner or later, human civilization must turn to renewable energies. This is deemed inevitable, considering the ever-growing energy demands of humanity and the finite nature of fossil fuels. Much research has been pursued in order to develop alternative sources of energy, most of which use electricity as the main energy carrier...

Astronomy’s newest mystery objects⁠—odd radio circles, or ORCs⁠—have been pulled into sharp focus by an international team of astronomers using the world’s most capable radio telescopes.
When first revealed in 2020 by the ASKAP radio telescope, owned and operated by Australia’s national science agency CSIRO, odd radio circles quickly became objects of fascination. Theories on what causes them ranged from galactic shockwaves to the throats of wormholes.

A new detailed image, captured by the South African Radio Astronomy Observatory’s MeerKAT radio telescope and publ...
