Infamous Mars meteorite contains organic molecules, but they aren’t proof of life

Organic molecules found in a Mars meteorite that crash-landed on Earth are not signs of life, but instead formed in chemical reactions between water and rock on the Red Planet about 4 billion years ago, a new study finds. These findings could shed light on the origins of the building blocks of life on early … Read more

Multiple sclerosis: Best evidence yet that condition is caused by Epstein-Barr virus

Loss of seed-hauling animals spells trouble for plants in warming world | Science

A slow death is creeping through Earth’s forests and other green landscapes. As animals are killed by hunters or forced away by logging, for example, the plants that depend on them to carry their seeds begin to disappear. Over time, trees and other plants may vanish. Climate change is accelerating this process, a new study … Read more

China’s Shenzhou 13 astronauts manually fly cargo ship for emergency docking test

China’s Shenzhou 13 astronauts conducted a manual rendezvous and docking test over the weekend to test emergency procedures for spacecraft visiting the Chinese space station. The complex test involved the Tianzhou 2 cargo spacecraft undocking from the Tianhe core module of China’s Tiangong space station. The astronauts aboard Tianhe then teleoperated Tianzhou 2, guiding it … Read more

Puzzling Parkinson’s protein plays essential role in immunity | Science

Progress in treating Parkinson’s disease—a progressive neurological illness that causes tremors, muscle rigidity, and dementia—has been painfully slow, in large part because scientists still don’t fully understand the molecular events that kill select brain cells. What they do know is Parkinson’s leaves behind a telltale mark: clumps of the misfolded alpha synuclein (αS) protein in … Read more

Mosaic Flight: NASA’s 100th flight director leads Mission Control

For over 60 years and more than 230 missions, teams of dedicated engineers and specialists in NASA’s Mission Control have provided ground support for astronauts in space and on the moon. Out of the thousands of people who staffed the consoles and backroom support areas in that time, less than 100 have led the room. … Read more

Endemic: What the term means and why covid-19 is far from getting there yet
