Jellyfish can be a nasty thing to encounter in the water, and they don't even have to be alive to leave a painful sting on anyone in their path. The New York Times reports that this was something a group of 150 people discovered in 2010 while swimming at Wallis Sands State Park in New Hampshire, when the 40-pound body of a lion's mane jellyfish floated through the water, stinging at will.

Distinct from the geographic North Pole, the magnetic North Pole—used in compass navigation—is in northern Canada and moves about 10 kilometers a year. As Scientific American explains, the shift occurs "under the influence of the dynamo currents in the Earth's core, as well as electric currents flowing in the ionosphere, the radiation belts, and the Earth's magnetosphere."

You're no doubt familiar with a shark's ability to detect even small amounts of blood in the water from as far as a quarter mile away. However, what you may not realize is that this is due to the animal's ability to "smell in stereo."

As reported in the journal Nature in 2010, sharks can detect tiny delays in the time it takes for a scent to reach one nostril compared to the other—even when it's just a fraction of a second. This delay allows them to determine from which side the scent came and in response, they can head that way in search of prey.

In 2007, a swath of land in northern Canada was found to have unusually low gravitational pulls. The reason for this, according to Science magazine, is because nearly 20,000 years ago, the weight of massive ice glaciers "caused some of the rock beneath to compress and sink, and in the process displace the underlying semifluid mantle."

NASA has found some pretty incredible things in space, and that includes a floating reservoir of water that holds the equivalent of 140 trillion times all the water that's in Earth's oceans. What makes it even more amazing is the fact that the reservoir surrounds a giant black hole.

More than 12 billion light-years away from Earth, the reservoir is more proof "that water is pervasive throughout the universe," says Matt Bradford, a scientist at NASA's Jet Propulsion Laboratory in Pasadena, California.

Italian athletes Simone Frediani and Daniele Pecci earned the world record for the longest tennis rally ever on June 11, 2017. Hitting for more than 12 and a half hours straight—from 6:23 a.m. to 7 p.m.—the two took a total of 51,283 uninterrupted strokes, sipping from water-filled backpacks to hydrate without having to stop play. Any good tennis player will tell you that consistency is crucial, and we're pretty sure these two have that part of the game down pretty darn well.

The majority of humans may be afraid of great white sharks, but that doesn't mean that the sharp-toothed ocean predators don't have fears of their own, one of them being another kind of big swimmer: orcas, also known as killer whales. In fact, a 2019 study published in the journal Nature suggests they're so terrified of the ferocious whales that they'll avoid an area for up to a year if they encounter one even if it's just passing by.

As the study's lead author Salvador Jorgensen explained, "When confronted by orcas, white sharks will immediately vacate their preferred hunting ground and will not return for up to a year, even though the orcas are only passing through."

It's hard to imagine anyone being able to speak—or even understand—all of the 850-plus indigenous languages that are spoken in Papua New Guinea. And in reality, most people don't. Many of the languages in the country—such as Nihali—are only spoken and understood by a few thousand people in the world. Still, the sheer number of languages that exist in Papua New Guinea make it one of the most linguistically diverse countries in the world.
