Scientists have made a baffling discovery: the Earth's spin is accelerating. In fact, the Earth is spinning faster than ever recorded.

Spin So Hard

Seriously — scientists say we may need to cut an entire second out of the year.

The Earth is Spinning So Fast, We Might Need to Skip a Second

Scientists are preparing to use an ultra-precise atomic clock to hunt oscillations of dark matter several orders of magnitude smaller than ever before.

The Hunt Continues

Scientists are pitting their most precise tools against extremely elusive particles.
