Paranormal claims and other pseudoscience often bedevil the study of language

People beat artificial intelligence hands-down at puzzling out new ways to fold molecules for a potential SARS-Cov-2 immunization. Thousands more players are needed.

Historically, the road to reform has often begun with protesters taking to the streets. A sociologist and a political scientist take stock of whether today’s activism will lead to actual change.

Exploring small bodies in the solar system provides clues to origins

The unlikely marriage of two major artificial intelligence approaches has given rise to a new hybrid called neurosymbolic AI. It’s taking baby steps toward reasoning like humans and might one day take the wheel in self-driving cars.

Bit by bit, biologists are deciphering the complex 3-D — and 4-D — architecture of the genome and learning how all the squeezed-together stuff of DNA keeps itself in order. What they find could lead to medical advances.

Kivu is no ordinary lake, with dense depths packed with methane and carbon dioxide gas. Its features hold aquatic puzzles, explosive hazards and the capacity to provide valuable energy.

False statements — about Covid-19 and so much else — spread like a virus online. Scientists should study them like one.

When polymers prove resistant to recycling, new chemical techniques can do the job of breaking them down for reuse

Modern industry has made great strides in turning trash into tomorrow’s new products, but the process is still a long way from perfect. New technologies can help. Plus, updates on chemical recycling, design for recycling and dirty recycling.
