Scientists have detected altermagnetism in ultrathin ruthenium dioxide films, a material previously thought nonmagnetic in bulk form, potentially enabling advances in computer memory technology.

Researchers propose that gravitational waves detected by pulsar timing arrays may originate from black holes seeded by mysterious dark stars over 13 billion years ago, offering new insights into early cosmic history.

Researchers analyzing ancient dental tartar found that Western aversion to eating insects has deep evolutionary roots dating back roughly 9,000 years, shaped by ecology and genetics rather than recent cultural factors alone.

Astronomers have captured the clearest image yet of a companion star orbiting Betelgeuse, a famous red supergiant visible to the naked eye, ending a century-long search for evidence of the stellar companion.

Two decades after Pluto’s 2006 demotion from planet to dwarf planet status, scientists remain divided over whether the International Astronomical Union’s decision was justified, with some arguing the definition is flawed.

Researchers found that some proposed quantum gravity experiments could be explained using classical gravity, suggesting apparent quantum gravity signatures may be illusory rather than definitive evidence.

New seismic analysis indicates the Juan de Fuca tectonic plate beneath northern Oregon lies shallower than previously estimated, potentially increasing ground shaking intensity from future Cascadia megathrust earthquakes by 9 to 17 percent.

Analysis of ancient Egyptian royal mummies reveals physical evidence that princesses were trained in weapons use, including archery and combat, rather than merely receiving ceremonial burial items.

Astronomers have identified S301, the fastest known star in the Milky Way, orbiting the galaxy’s central supermassive black hole at approximately 25,000 km per second.

International researchers identified seven previously unknown frog species in Madagascar, bringing the total known diamond frogs to 27 and highlighting the region’s hidden biodiversity.

Chemists have developed a novel method to create nanocrystals from metal nitrides, materials that previously resisted conventional synthesis, opening possibilities for flexible electronics and medical implants.

Scientists have discovered a massive heat anomaly deep inside Mars, with the southern hemisphere’s interior significantly hotter than the north, potentially providing insights into the planet’s geologic history and past habitability.
