Every human cell has millions of ribosomes that make proteins. For decades, biologists thought of ribosomes as tiny, uniform machines. But now a Stanford Medicine team is showing that ribosomes are much more interesting and complicated than previously thought.
Long before a human ever sets foot on the Red Planet, we already know how harsh the environment is. Once a human finally does, the only things protecting them from that environment will be the infrastructure we've built there and the spacesuit that keeps them in a protective
The arms race between bacteria and antibiotics is nothing new—antimicrobial resistance has been an emerging issue in human and animal health for a long time. But in a new review published in JAC-Antimicrobial Resistance, NC State researchers used a One Health approach to study
Cancer cells survive by hiding from the immune system's surveillance. A KAIST research team has developed a new anticancer platform that makes cancer cells send out their own danger signals—prompting immune cells to attack—while simultaneously delivering gene therapy. The
Sixty-six million years ago, the six-mile-wide (10-kilometer-wide) Chicxulub asteroid crash-landed in Mexico's Yucatán Peninsula and changed life on Earth forever. The reign of the dinosaurs ended, and only creatures that could shelter in burrows or shallow waters survived into
Around the world, hundreds of thousands of people engage in conventional protests—and sometimes more radical forms of action—in the face of environmental change, harms to animals and nature, and climate inaction.
Common dolphins in New Zealand are biologically older than their calendar ages. Trace metals and “forever chemicals” may be to blame.
