Altermagnets are a newly recognized class of antiferromagnets whose magnetic structure behaves very differently from what is found in conventional systems. In conventional antiferromagnets, the sublattices are linked by simple ...

Legend once had it that the huge, three-toed footprints scattered across the central highlands of Bolivia came from supernaturally strong monsters—capable of sinking their claws even into solid stone.

In the Middle Ages, a plague killed a third of Europe's population. Fleas carried the plague bacterium, Yersinia pestis, transmitting the Black Death from infected rats to millions of people.

Gamma-ray bursts (GRBs) are among the most powerful explosions in the universe, second only to the Big Bang. The majority of these bursts are observed to flash and fade within a few seconds to minutes. But on 2 July 2025, ...

An elusive wild cat long feared extinct in Thailand has been rediscovered three decades after the last recorded sighting, conservation authorities and an NGO said Friday.

Tiny tubes of carbon that emit single photons from just one point along their length have been made in a deterministic manner by RIKEN researchers. Such carbon nanotubes could form the basis of future quantum technologies ...

In a study published in Latin American Antiquity, Dr. Julien Hiquet and Dr. Rémi Méreuze analyzed the remains of a unique mosaic-style patolli game board discovered in the Classic Period city of Naachtun, Guatemala.

A collaboration between the University of Huddersfield's Archaeogenetics Research Group and the University of Southampton's Center for Maritime Archaeology, has clarified the first settlement of New Guinea and Australia by ...

For the first time, scientists have observed the iconic Shapiro steps, a staircase-like quantum effect, in ultracold atoms.

The gut microbiome is intimately linked to human health and weight. Differences in the gut microbiome—the bacteria and fungi in the gut—are associated with obesity and weight gain, raising the possibility that changing ...

Graphene is often described as a wonder material. It is strong, electrically conductive, thermally efficient, and remarkably versatile. Yet despite more than a decade of excitement, many graphene-based technologies still ...

Imaging technology has transformed how we observe the universe—from mapping distant galaxies with radio telescope arrays to unlocking microscopic details inside living cells. Yet despite decades of innovation, a fundamental ...
