In the early history of our solar system, scientists theorize that a Mars-sized object called Theia smashed into the infant Earth, vaporizing massive amounts of rock and blasting it into space. Some of that material coalesced into the moon, where NASA’s Artemis program is returning humans, preparing for Mars and shaping the future of space exploration.

That long-ago, violent collision reshaped our home planet...

JWST reveals that newborn planets are racing against powerful winds and radiation before their supply of planet-building gas disappears. JWST has revealed that young planetary systems lose their planet-building gas through a changing mix of powerful jets, molecular winds, and radiation-driven outflows. As the disks age and their gas disappears, giant planets face a shrinking window to build massive atmospheres.

Planets take shape inside disks of gas and dust surrounding young stars, but the supply of gas they depend on is temporary...

The atoms of the 5th element of the periodic table often find themselves in the company of each other, forming allotropes with a rich variety of structural motifs, each carrying a unique set of chemical and physical properties. Despite the long catalog, most boron allotropes do not simultaneously possess high electrical conductivity and plasticity, but a recent study has expanded the portfolio.

Scientists have now designed a new allotrope called Imma-B60 by washing out the sodium from the sodium boride compound Na4B60. Their findings are published in Nature Chemistry.

Unlike the dense, tightly packed atomic arrang...

A Husker research team’s latest research could open the door to broader use of a class of materials whose electrical properties may someday power next-generation electronics, high-density energy storage, improved computer memory and new strategies for cooling.

In a new paper published in Science, University of Nebraska–Lincoln researchers Xiaoshan Xu, Alexei Gruverman and Evgeny Tsymbal demonstrate that hafnium oxide—a tough, heat-resistant chemical compound used widely in modern electronics—is inherently antiferroelectric, a rare quality found in very few materials. Unlike hafnium oxide, also known as hafnia, many intrinsically antiferroelectric materials contain the toxin lead, which limits their widespread use.

The trio said the discovery will help settle a longstanding...
