The Scientist spoke with Brigham and Women’s Hospital and Harvard Medical School researchers Scott Weiss and Yang-Yu Liu, who propose that people bank stool samples when they’re young and healthy so that they can be transplanted to rejuvenate the gut microbiome later on.

A newer dating technique using cosmogenic isotopes finds Australopithecus remains from the Sterkfontein caves to be about 1 million years older than previous estimates, potentially changing scientists’ understanding of humanity’s origins.

This month marks ten years since CRISPR-Cas9 was repurposed as a gene editing system, so we’re looking back at what has been accomplished in a decade of CRISPR editing.

A new CRISPR screening technology allows scientists to recreate tumor heterogeneity in vivo and study how it affects all aspects of cancer biology.

Dormant cancer cells and dysfunctional immune cells living together in a tumor niche form a therapy-resistant reservoir.

A novel atlas reveals region-specific links between structural, mechanical, and genetic properties within the heart.

At about 2 centimeters in length, Thiomargarita magnifica tests scientists’ notions of how large microbes can grow.

Pairs of same-sex friends who reported strong connections when they first met had similar body odors, and body odor similarity predicted whether two strangers would hit it off.

The longer and farther the virus spreads, the more likely it could become endemic in new areas, says UCLA epidemiologist Anne Rimoin.
