Science News: Recent scientific discoveries and expert analysis

Physicists have analyzed two enormous black hole mergers that happened one month apart and have come up with tantalizing evidence that rare "second-generation" black holes were involved.

A rare and unique Celtic coin was discovered in Saxony, Germany, even though the Celts didn't live there.

Researchers have gained new insights into rhinoceros evolution and the longevity of the North Atlantic Land Bridge from analyzing the perfectly preserved fossils of a "frosty" Arctic rhino.

An argument over whether fossils from several small dinosaurs represent a juvenile Tyrannosaurus rex or smaller adults of a separate species may finally be settled.

Interstellar comet 3I/ATLAS is briefly out of view as it travels around the sun this week, but researchers and amateur astronomers used spacecraft data to track its progress right up until perihelion.

Researchers armed with a new "photonic lantern" device have discovered an unexpectedly asymmetrical disk of gas swirling around a mysterious star 162 light-years from Earth. The new technology could revolutionize ground-based astronomy, the researchers claim.

New ESA simulations suggest that a solar storm on par with the 1859 Carrington Event could wreak havoc on Earth-orbiting satellites — and it is a question of "when," not "if" this will happen, experts say.

An early-stage study has found that a common chemotherapy drug disrupts lymphatic cells in the tissue surrounding the brain. This is linked to memory issues in mice.

Earth's mantle is so gooey, it takes eons for material that has been displaced by the weight of ice sheets to flow back. And Greenland is very much still processing its glacial past, a new study shows.

Scientists have spotted elusive "magnetic waves" in the sun's atmosphere that may explain why the sun's corona is much hotter than its surface.

Archaeologists have recovered three unusual burials of Celtic women and girls who may have been sacrificed in England.

Authorities have killed several lab monkeys that escaped from an overturned truck in Mississippi. The rhesus macaques were initially thought to be diseased and dangerous, but that's not necessarily the case.

A gene on the X chromosome revs up inflammation in the female brain, which may explain why rates of multiple sclerosis are higher in women than in men, scientists suggest.

Researchers have developed a chemical structure for an artificial muscle that can lift up to 4,000 times its weight, and they say it could be used in future humanoid robots.

Archaeologists in Hungary have found the 1,300-year-old burial of a warrior who was buried with a rare iron saber.

Earth's systems are nearing tipping points that could plunge the planet into a "hothouse" regime — but there's still time to prevent that from happening, scientists say.

Researchers have unearthed two dinosaur "mummies" in the badlands of Wyoming, confirming duck-billed dinosaurs had hooves, alongside a string of other discoveries.

New observations from the James Webb Space Telescope have uncovered five complex organic molecules trapped in the ice around a star outside our galaxy. This cosmic first hints that the stuff of life may be widespread throughout space.

An astronomer in Italy caught a fortuitous image of the bright comet Lemmon seemingly entwined with the glowing trail of a "shooting star."

The U.S. Air Force's "Hurricane Hunters" have flown inside the eye of Hurricane Melissa, capturing eerie footage of the historic storm that has caused widespread devastation in Jamaica.
