Scientists find evidence of virus-eating microorganisms

Scientists have found the first compelling evidence that two groups of ecologically important marine microorganisms could be eating viruses -- catching their “prey” and engulfing them, an advance that may lead to a better understanding of the flow of organic matter in the oceans.

The findings, published in the journal Frontiers in Microbiology, go against the currently predominant views of the role of both viruses and these groups of single-celled organisms called protists in the marine food webs.(Unsplash)

New measurements show moon has hazardous radiation levels

Future moon explorers will be bombarded with two to three times more radiation than astronauts aboard the International Space Station, a health hazard that will require thick-walled shelters for protection.

Highly effective coronavirus antibodies identified, may lead to passive Covid-19 vaccine

The research, published in the journal Cell, also shows that some SARS-CoV-2 antibodies bind to tissue samples from various organs, which could potentially trigger undesired side effects.

NASA’s new Mars Rover will use x-rays to hunt fossils

NASA’s Mars 2020 Perseverance rover has a challenging road ahead: after having to make it through the harrowing entry, descent, and landing phase of the mission on February 18, 2021, it will begin searching for traces of microscopic life from billions of years back.

Nearly every mission that has successfully landed on Mars, from the Viking landers to the Curiosity rover, has included an X-ray fluorescence spectrometer of some kind.(Twitter @NASAPersevere)

Human footprints dating back 120,000 years found in Saudi Arabia

In addition to footprints, over 200 fossils were also recovered. The discoveries were made in the Nefud Desert.

A detailed scene was reconstructed by researchers in a new study published in Science Advances on September 16, 2020, following the discovery of ancient human and animal footprints in the Nefud Desert that shed new light on the routes our ancient ancestors took as they spread out of Africa.

These scientists are studying why California keeps burning

As fire last week taunted Paradise, California, destroyed in the 2018 Camp Fire, many others have found themselves asking a related, but much more complicated question: How can this be happening again?” California burns. Everybody knows that. But why does it seem like forests are igniting more often?

TOPSHOT - A firefighter watches the Bobcat Fire burning on hillsides near Monrovia Canyon Park in Monrovia, California on September 15, 2020. - A major fire that has been raging outside Los Angeles for more than a week threatened to engulf a historic observatory and billion-dollar broadcast towers on September 15 as firefighters struggled to contain the flames. The so-called Bobcat Fire was within 500 feet (150 meters) from the 116-year-old Mt. Wilson Observatory, the US Forest Service said in a tweet, while fire officials said crews were in place

Venus, named for the goddess of love, is no cuddly place

Scientists have spotted evidence of potential life on the planet Venus, though they emphasized that more work needs to be done to confirm whether or not life - possibly aerial microbes - exists or whether there is an alternative non-biological explanation for their findings.

This artistic illustration depicts the Venusian surface and atmosphere, as well as phosphine molecules. These molecules float in the windblown clouds of Venus at altitudes of 55 to 80 km, absorbing some of the millimetre waves that are produced at lower altitudes. They were detected in Venus’s high clouds in data from the James Clerk Maxwell Telescope and the Atacama Large Millimeter/submillimeter Array, in which ESO is a partner.(via REUTERS)

Dark matter destruction ruled out in galactic center

The detection more than a decade ago by the Fermi Gamma-ray Space Telescope of an excess of high-energy radiation in the centre of the Milky Way convinced some physicists that they were seeing evidence of the annihilation of dark matter particles.

Antarctica remains the only continent without Covid-19 and now in Sept. 2020, as nearly 1,000 scientists and others who wintered over on the ice are seeing the sun for the first time in months, a global effort wants to make sure incoming colleagues don't bring the virus with them.(AP)
