A new record for maintaining plasma burning inside a fusion reactor has been set in France, beating China's previous benchmark by 25%.

Indian teenager Aaryan Shulka performs calculations in his head quicker than most people can use a calculator. At a recent event hosted by Guinness World Records, 14-year-old Shulka shattered six mental math records in one day.

Nuclear bunkers aren't a foolproof way to stay safe during a nuclear attack. Here's why.

How do Hula-Hoops keep from falling down as we twirl them around?

Because we haven't found anything yet, we've started to wonder if dark matter might be lighter or heavier than we thought.

Scientists have found an elusive third form of magnetism that could help solve a longstanding puzzle about superconductors.

"As yet, nobody has managed to understand what gives rise to this strange phenomenon, and explaining dark energy remains one of the most formidable challenges of modern science."

New research suggests that dark energy isn't needed to explain the acceleration in the expansion of the universe — instead suggesting giant voids in space are creating an illusion.

Physicists have long-suspected that the building blocks of protons experienced quantum entanglement. Now, researchers have the first direct evidence — after using a trick to infer subatomic particles' entropy.

The cores of galaxies may not be made of what we thought, new research suggests — they could hold one giant, invisible star made of mysterious "fuzzy" matter.
