| Could acid-neutralizing life-forms make habitable pockets in Venus' clouds? Posted: 20 Dec 2021 04:06 PM PST A new study supports the longstanding idea that if life exists, it might make a home in Venus' clouds. The study's authors identified a chemical pathway by which life could neutralize Venus' acidic environment, creating a self-sustaining, habitable pocket in the clouds. |
| Can a dangerous microbe offer a new way to silence pain? Posted: 20 Dec 2021 09:06 AM PST A new study shows that a toxin from the microbe that causes anthrax can silence multiple types of pain in mice. Researchers found the toxin targets pain-sensing cells to alter signaling and block pain. Building on that finding, researchers engineered an anthrax protein vehicle to deliver different types of treatments into pain receptors and modulate nerve-cell function. The findings can inform the design of therapies that selectively target pain-sensing fibers without the widespread systemic effects of opioids and other pain killers. |
| Himalayan glaciers melting at 'exceptional rate' Posted: 20 Dec 2021 05:31 AM PST The accelerating melting of the Himalayan glaciers threatens the water supply of millions of people in Asia, new research warns. The study concludes that over recent decades the Himalayan glaciers have lost ice ten times more quickly over the last few decades than on average since the last major glacier expansion 400-700 years ago, a period known as the Little Ice Age. |
| Shark antibody-like proteins neutralize COVID-19 virus, help prepare for future coronaviruses Posted: 17 Dec 2021 07:29 AM PST Small, unique antibody-like proteins known as VNARs -- derived from the immune systems of sharks -- can prevent the virus that causes COVID-19, its variants, and related coronaviruses from infecting human cells, according to a new study. |
