Earth’s spin is not as steady as it looks from the ground. As ice sheets melt and aquifers are drained, scientists now say ...

We’ve probably all had a few conversations with people who hold eccentric scientific ideas, and most of the time they yield ...

Earth’s spin is not as steady as it looks. As ice melts and groundwater is pumped from deep aquifers to the surface, the ...

As if it's not already hard enough to find the time to do everything you need to do in a day, now you're about to lose another whole millisecond or more. In fact, experts say Tuesday, July 22, could ...

Does it feel like there's not enough time in the day for everything? Well, that could be because some upcoming days are actually getting shorter. In fact, today might just be the shortest day you'll ...

Aren’t the summer days supposed to be longer and the winter days shorter? Since when have things gone in reverse for the summertime? Since now, maybe? Starting today? Okay, here’s what’s going on.

Earth takes 24 hours to complete a full rotation in a standard day, equal to exactly 86,400 seconds. July 9 was the first of three days in which a millisecond or more could be shaved off the clock on ...

On those three days, just over a millisecond is expected to be shaved off the standard 24-hour day. Of course, you're unlikely to notice such a miniscule difference in your day. But scientists who ...
