Clovis only made stone tools for about 300 years

The Clovis, some of North America’s earliest inhabitants, only made stone tools during a brief 300-year period from 13,050 to 12,750 years ago, new research shows. There is much debate surrounding the age of the Clovis—a prehistoric culture named for stone tools found near Clovis, New Mexico in the early 1930s—who once occupied North America…

Imaging tech captures molecule ‘wobble’ in 3D

Researchers have found a way to visualize individual molecules inside living cells in greater detail, showing their position and orientation in 3D, and even how they wobble and oscillate. The work could shed invaluable insights into the biological processes involved, for example, when a cell and the proteins that regulate its functions react to the…

Fake ‘grammar’ shows apes get language basics

Humans are not the only ones that can identify rules in complex language-like constructions—monkeys and great apes can, too, according to a new study. Researchers used a series of experiments based on an “artificial grammar” to conclude that this ability can be traced back to our ancient primate ancestors. “This suggests that this crucial element…

Mask vs. muzzle: Even words are now polarized

In the United States, even the meanings of some words are now polarized, research finds. Everyone is speaking English, say the scientists, but computer analysis of social media discussions shows viewers of different news channels are, in a sense, speaking different languages. Based on millions of user comments on the YouTube channels for four leading…

Little bat-winged dinos could glide, but not fly

Two small dinosaurs with bat-like wings struggled to fly but could glide clumsily between trees, researchers report. Unable to compete with other tree-dwelling dinosaurs and early birds, Yi and Ambopteryx went extinct after just a few million years. The findings, published in iScience, support that dinosaurs evolved flight in several different ways before modern birds…
