If and when physicists are able to pin down the metal content of the sun, that number could upend much of what we thought we knew about the evolution and life span of stars.

This year’s Nobel Prize in Chemistry goes to researchers who made it possible to see proteins and other biomolecules at an atomic level of detail.

Textbooks say that the moon was formed after a Mars-size mass smashed the young Earth. But new evidence has cast doubt on that story, leaving researchers to dream up new ways to get a giant rock into orbit.

The subtle mechanics of densely packed cells may help explain why some cancerous tumors stay put while others break off and spread through the body.

Scientists have figured out how microbes can suck energy from rocks. Such lifeforms might be more widespread than anyone anticipated.

Searching for signs of life on faraway planets, astrobiologists must decide which telltale biosignature gases to target.

All life on Earth is made of molecules that twist in the same direction. New research reveals that this may not always have been so.

Scientists have discovered building blocks similar to those in modern RNA that can effortlessly assemble when mixed in water and heated.
