Lifelike biochemistry continued to unfold in sterilized soil for six years, pointing to a metabolic theory for how biology began.

Do we need quantum computers to fully understand complex chemical reactions? A new result, decades in the making, shows the surprising power of ordinary “classical” machines.

Scientists keep detecting new forms of ice. According to simulations, there could be many more left to find.

Rare and powerful compounds, known as keystone molecules, can build a web of invisible interactions among species.

Wherever astronomers look, they see life’s raw materials.

Making ice requires more than subzero temperatures. The unpredictable process takes microscopic scaffolding, random jiggling and often a little bit of bacteria.

The Nobel Prize in Chemistry has been awarded to three researchers who harnessed the quantum behaviors of semiconductor nanocrystals.

To buffer the brain against menaces in the blood, a dynamic, multi-tiered system of protection is built into the brain’s blood vessels.

After decades of frustration, researchers have determined how an airborne scent molecule links to a human smell receptor.
