'Nothing short of a minor miracle': 'Rusty treasure' found in the Danube is full of 2,000-year-old iron bars that could equip an entire army with weapons

Archaeologists in Austria have analyzed a collection of 500 iron bars that were likely lost in a Danube shipwreck 2,200 years ago. This "rusty treasure" is the largest cache of ancient iron ever discovered in Europe.

'Farting' comet does something never seen before

In 2017, the Hubble Space Telescope saw something strange happening to Comet 41P Tuttle-Giacobini-Kresák. During a flyby of Earth, the object's spin suddenly slowed and then sped back up again, hinting at an exceptionally strong bout of "outgassing" that could eventually cause the comet to self-destruct, researchers claim.

An 'impossible' black hole merger may finally be solved thanks to Einstein's relativity — but it raises an even bigger mystery

New research suggests that a perplexing signal created by a pair of colliding black holes may have been warped by a space-time phenomenon known as gravitational lensing. This theory could explain the "impossible" size of the merging singularities, but it also poses a new problem.

Scientists build a DNA computer that can perform calculations in a drop of water

Scientists have built a DNA-powered computer that can perform calculations using billions of molecules in a tiny drop of water. The system taps into the laws of physics to create what the scientists describe as a computing system that's more efficient than the conventional computers that are widely used today.
