As the afternoon breezes blow harder in the Atacama Desert—a place so desolate it’s used as a model of Mars—more microbes move into its driest regions.

Using a tiny thermometer, researchers record fluctuations of more than 7 Kelvin in sea slug neurons when a heat-generating mitochondrial process is switched on.

Habits such as napping might influence how humans cope with extreme environments, such as those at a polar research facility in winter.

Researchers plan an oceanographic expedition to understand why a phytoplankton bloom developed as molten lava flowed into the sea east of Hawaii's Big Island.

DNA-responsive polymer gels used for releasing drugs, encapsulating cells, and much more now have greater adaptability thanks to the Cas12a nuclease.

Organelles isolated from two types of neurons and a nonneuronal astrocyte in the mouse cerebellum showed varying levels of proteins, hinting at functional differences.

The drug, called memantine, could enter clinical trials to determine its effectiveness in humans.

A single-cell map of C. elegans’s transcriptome during development finds cell lineages that start out genetically different and end up as cells of similar function and genetic profile.

The cell and molecular biologist unveiled a role for the breakdown of proteins in the extracellular matrix in both healthy and pathogenic cells.

The Stanford University professor helped develop a technique to grow brain organoids from induced pluripotent stem cells.

Speaking a common language is key to a well-integrated team, but guidance is sparse on what—if anything—principal investigators should do about it.
