Each week we uncover the most interesting and informative articles from around the world, here are 10 of the coolest stories in science this week.
Teleportation Records
Chinese scientists have just shattered a record in teleportation. No, they haven't beamed anyone up to a spaceship. Rather, they sent a packet of information from Tibet to a satellite in orbit, up to 870 miles (1,400 kilometers) above the Earth's surface.
Experiments like this have been done before, but Howard Wiseman, director of the Center for Quantum Dynamics at Griffith University in Brisbane, Australia, told Live Science in an email that this one expands the possibilities for the technology. [Read more about the big jump.]
A Big Break
One of the largest icebergs ever recorded, packing about a trillion tons of ice or enough to fill up two Lake Eries, has just split off from Antarctica, in a much anticipated, though not celebrated, calving event.
The iceberg was expected, though scientists didn't know when the crack in the ice sheet would finally release the floating chunk. The rift in the Larsen C ice shelf — the fourth-largest shelf in Antarctica — has been around for decades. [Read more about the giant iceberg.]
Nasty Mess
A truck carrying a bunch of slime eels recently crashed on the highway in Oregon, releasing a mind-boggling amount of slime and forcing the highway to close.
It turns out that the creatures aren't truly eels at all, but are hagfish, or primitive, bottom-dwelling fish that use their slime to fend off predators, several experts said. [Read more about the slimy situation.]
Super-Sized Super Soaker
If you're going to challenge someone to a water gun fight this summer, it's best you don't take up arms against Mark Rober, a former NASA engineer who has created the world's largest Super Soaker.
The Super Soaker that Rober made with his friends works in a slightly different manner. It would be too cumbersome and difficult to pump up a 7-foot-long pistol, so instead, they installed two tanks — one with high-pressure nitrogen gas and the other with water — in the gun's handle.

Water Bears are Tough
The eight-legged micro-animal called a tardigrade could survive nearly all the way until the death of the sun, a new study suggests — long after humans are history.
Tardigrades, which are usually less than a millimeter long (0.04 inches), are nearly indestructible, some of the most resilient forms of life on Earth. They can survive for up to 30 years without eating, and can be frozen, boiled, squished under intense pressure, and exposed to the vacuum and radiation of space without ill effect.

Surprisingly Big
If you thought flash drives were small, wait until you see this: Researchers have encoded the data to make a short video into the DNA molecules of bacteria. They also were able to retrieve the information from the genetic code and play back the movie.
Although it may seem like this project would have very limited applications to real life, researchers say they have goals far beyond the scope of the current study. [Read more about the movie.]
Flea Market FindA World-War II era German Enigma 1 machine recently sold at auction for about $51,000.
A German cryptography machine found at a flea market recently fetched $51,000 at auction.
Enigma machines were special encryption machines that were used by the Germans during World War II to send secure messages to their forces. While the initial code was cracked by Polish mathematicians on the eve of World War II, that didn't get them very far. [Read more about the rare machine.]
Finding Amelia
It's not her.
History channel researchers had claimed the image showed Earhart after she had been taken hostage as a suspected spy by the Japanese, who had a military presence in the Marshall Islands, where the photo was taken. [Read more about the photo.]
Beer and Birthdays
A cache of secret letters has been unearthed near the site of an ancient Roman fort in the United Kingdom.
The trove of Roman letters was in surprisingly pristine condition, thanks to the oxygen-free, or anaerobic, conditions in which they were buried. As a result, bacteria that normally degrade such items over time have not had a chance to attack the artifacts. [Read more about the birthday wishes.]
Early Animals, Special Powers
Some of Earth's first large animals were shape-shifters, new research suggests.
Now, new measurements of these frondy fossils suggest that these animals, called rangeomorphs, were able to adjust their body size in response to changing ocean conditions. This shape-shifting ability may have enabled them to grow very large, very quickly. [Read more about the shape-shifters.]
