Parenting may have evolved by repurposing the brain’s ancient hunger circuits. Long before parenting became widespread, many animals simply laid eggs and left their offspring to survive alone. A new study published in Nature reveals how evolution may have turned that lack of care into nurturing behavior. By studying clonal raider ants, an insect known […]
A Fiber Frozen at -196°C Unlocks a New Way To Store Light
A frozen-core optical fiber has revealed a powerful new way to control interactions between light and sound. Molten lava hardens into rock as it cools, much as the surface of a lake freezes during a cold winter. In both cases, a liquid becomes a solid, changing physical properties such as density and refractive index, which […]

Alien Signals May Be Hiding in a Radio Band SETI Has Barely Explored
Archived radio observations could open new frequencies to SETI while showing that past searches covered millions more stars than previously estimated. A potential extraterrestrial signal could be hiding in radio frequencies that modern searches for intelligent life have barely examined. Most radio SETI (Search for Extraterrestrial Intelligence) projects concentrate on frequencies from 1.42 to 1.66 […]
Scientists Crack the Code for Making “Impossible” Nanocrystals
A molten salt method developed by researchers at UChicago and Argonne could enable more durable materials for printed electronics and flexible devices. Nanocrystals have become so valuable to science and technology that research involving them earned the 2023 Nobel Prize in Chemistry. Yet despite their potential, researchers have only been able to produce these microscopic […]
