Using a new radio telescope, researchers mapped the galaxy’s magnetic field in unprecedented detail and discovered that a mysterious reversal in the Sagittarius Arm cuts diagonally across space. The finding could reshape how scientists understand the structure and future evolution of our galaxy.

By analyzing tiny traces of DNA in the animals’ scat, researchers uncovered clues about the elusive fungi the potoroos depend on for survival. The findings could help conservationists identify safer new habitats and establish backup populations before disasters like bushfires wipe them out.

Measurements from mine boreholes in Ontario show the gas can flow continuously for years, offering a potential new source of clean energy called “white hydrogen.” Researchers say this hidden resource could help power industries and remote communities while cutting carbon emissions and reducing dependence on fossil fuels.

Scientists now think it’s because its giant head became the ultimate hunting tool. Across multiple dinosaur groups, stronger skulls and crushing jaws evolved alongside shrinking forelimbs, especially in predators hunting enormous prey. In other words, once the bite became deadly enough, the arms may have stopped mattering.

One whale shattered records by covering at least 15,100 kilometers between sightings, marking the longest confirmed journey ever documented for an individual humpback whale.

But a groundbreaking discovery in West Africa is rewriting that story. Researchers uncovered evidence that humans were living deep within rainforest environments in present-day Côte d'Ivoire around 150,000 years ago — far earlier than anyone thought possible.

Physicists created a new model predicting how dark matter could subtly distort gravitational waves produced during black hole mergers. When they tested the method on real LIGO data, one signal stood out as potentially carrying a dark matter imprint.

Instead of assuming strings existed from the start, researchers began with a few simple rules about how particles behave at extreme energies and discovered that the equations naturally produced the telltale fingerprints of string theory all on their own.
