Phys.org / Did wildfires help spark the invention of pottery?

A new study suggests that a period of intense fires and landscape upheaval in the ancient southern Levant may have helped create the conditions that led Neolithic communities to discover how fire could transform clay.

Phys.org / Curved nanographene with five-, six- and seven-membered rings synthesized in two steps

Nanographenes can be considered molecular fragments of graphene, a 2D conductive material in which carbon atoms are connected in a honeycomb pattern. Because their electronic and photophysical properties vary depending on ...

Phys.org / JWST finds extreme star-forming galaxies masquerading as faint quasars

A new study finds that two early-universe objects thought to be faint quasars are actually extraordinarily luminous galaxies powered by bursts of star formation. James Webb Space Telescope observations of the galaxies, seen ...

Phys.org / Hubble and Webb find that far-out solar system objects 'remember' the past

For the first time, scientists used the combined power of NASA's Hubble and James Webb Space Telescopes to study some of the most far-flung bodies in our solar system, trans-Neptunian objects (TNOs). Some are the smallest ...

Phys.org / Star-fingered toads use fingertip lobules to detect prey in murky water

Surinam toads (Pipa pipa) are strange, flat frogs with minuscule eyes that live in the murky waters of the Amazon basin and carry their eggs on their backs. The way they catch prey is even weirder. They lie in wait with outstretched ...

Phys.org / New iron-bearing compounds could store water near Earth's core

Geochemical studies of volcanic rocks from Baffin Island, Canada, and Iceland suggest that some of the water dating back to Earth's formation may still be preserved deep within the planet. However, it has remained unclear ...

Phys.org / New screening system flags food-packaging chemicals linked to serious health risks

Packaged food usually sits in plastic-lined bags designed to keep air, moisture and contaminants out. That same protection can also increase the chances of chemicals from the packaging seeping into the food. When a chemical ...

Phys.org / Study predicts large disparities in access to food, water and energy in 2050

How will global access to food, water and energy evolve in coming decades? A new study coauthored by MIT researchers suggests the answers could be very different depending on region, resource and income.
