Phys.org / From the Pampas to Patagonia, DNA reveals South America's human history

A new genetic study shows that cultural diversity in the so-called Southern Cone—the roughly triangular southernmost part of South America—was strongly influenced by extensive human migration. An international research team ...

Phys.org / What if humans could regrow tissue? New study moves science closer

For centuries, the inability to regrow lost body parts has been considered a defining limitation of humans and other mammals. While animals like salamanders can regenerate entire limbs, humans are left with scar tissue. But ...

Phys.org / Why more gut and soil microbes could make ecosystems easier to predict

Much of the beauty—and challenge—of biology lies in its complexity. That's especially true in the microbial world, where hundreds or thousands of different bacterial species may co-exist in a patch of soil or in a section ...

Phys.org / Divergent moral values could make groups more accepting of norm-breaking behavior

Individuals in a morally diverse community tend to believe that the community's norms are looser. In turn, norm violations are more accepted, and there is a reduced willingness to police transgressions, according to research ...
