First look at Ryugu asteroid sample reveals it is organic-rich

Asteroid Ryugu has a rich complement of organic molecules, according to a NASA and international team's initial analysis of a sample from the asteroid's surface delivered to Earth by Japan's Hayabusa2 spacecraft. The discovery ...

A new perspective on how early protein-RNA interactions evolved

Protein-RNA complexes are ubiquitous in modern life and are essential to many stages of the cell cycle and metabolism. New research presents experimental support to provide a new perspective on how early protein-RNA interactions ...

Discovery of a mechanism for efficient autophagosome formation

Drs. Nobuo Noda (Director) and Tatsuro Maruyama (Researcher) et al. at the Institute of Microbial Chemistry (BIKAKEN, Tokyo, Japan) discovered that lipidated Atg8, the most famous factor that mediates autophagy, has membrane ...

Did comet impacts jump-start life on Earth?

Comets screaming through the atmosphere of early Earth at tens of thousands of miles per hour likely contained measurable amounts of protein-forming amino acids. Upon impact, these amino acids self-assembled into significantly ...

Many more bacteria have electrically conducting filaments

Microbiologists led by Derek Lovley at the University of Massachusetts Amherst, who is internationally known for having discovered electrically conducting microfilaments or "nanowires" in the bacterium Geobacter, announce ...
