A WWII Navy Submarine, Lost for 75 Years, Has Been Discovered Off the Coast of Japan

The U.S. Navy lost 52 submarines during World War II, many of which are still missing today. But as The New York Times reports, the wreck of the U.S.S. Grayback—a submarine that disappeared along with its 80-person crew in 1944—has been found off the coast of Okinawa, Japan.

On January 28, 1944, the Grayback departed from Pearl Harbor for its 10th combat patrol. It missed its scheduled return date that spring, and after weeks of failing to locate the vessel, the Navy declared it was likely lost.

Immediately following World War II, the U.S. military studied Japanese war records in search of clues that might lead them to their missing ships. One recording clearly states the Grayback was brought down by a bomb dropped by an Japanese aircraft, and it even gives the longitude and latitude of the attack. But due to a poor translation of the audio, the Navy went looking for the sub 100 miles away from its actual resting place.

Seventy-five years later, the submarine's coordinates were finally uncovered in old Imperial Japanese Navy files.

A Japanese researcher named Yutaka Iwasaki noticed this error while looking at the World War II records of the Imperial Japanese Navy base at Sasebo. He was asked to review the files for the Lost 52 Project, an organization dedicated to finding lost World War II submarines. Using the newly uncovered information and an autonomous underwater vehicle, the team was able to locate the vessel at the bottom of the East China Sea near Okinawa.

Lost 52 doesn't hunt for submarine wrecks with plans to recover them. Rather, the goal of the project is "documenting and preserving the story of the Lost 52 WWII Submarines, leaving a foundation of knowledge for future generations." In the case of the Grayback, the site where it settled on the seafloor will be protected from any human interference.

Turn Your LEGO Bricks Into a Drone With the Flybrix Drone Kit

Now more than ever, it’s important to have a good hobby. Of course, a lot of people—maybe even you—have been obsessed with learning TikTok dances and baking sourdough bread for the last few months, but those hobbies can wear out their welcome pretty fast. So if you or someone you love is looking for something that’s a little more intellectually stimulating, you need to check out the Flybrix LEGO drone kit from Fat Brain Toys.

What is a Flybrix LEGO Drone Kit?

The Flybrix drone kit lets you build your own drones out of LEGO bricks and fly them around your house using your smartphone as a remote control (via Bluetooth). The kit itself comes with absolutely everything you need to start flying almost immediately, including a bag of 56-plus LEGO bricks, a LEGO figure pilot, eight quick-connect motors, eight propellers, a propeller wrench, a pre-programmed Flybrix flight board PCB, a USB data cord, a LiPo battery, and a USB LiPo battery charger. All you’ll have to do is download the Flybrix Configuration Software, the Bluetooth Flight Control App, and access online instructions and tutorials.

Experiment with your own designs.

The Flybrix LEGO drone kit is specifically designed to promote exploration and experimentation. All the components are tough and can totally withstand a few crash landings, so you can build and rebuild your own drones until you come up with the perfect design. Then you can do it all again. Try different motor arrangements, add your own LEGO bricks, experiment with different shapes—this kit is a wannabe engineer’s dream.

For the more advanced STEM learners out there, Flybrix lets you experiment with coding and block-based coding. It uses an arduino-based hackable circuit board, and the Flybrix app has advanced features that let you try your hand at software design.

Who is the Flybrix LEGO Drone Kit for?

Flybrix is a really fun way to introduce a number of core STEM concepts, which makes it ideal for kids—and technically, that’s who it was designed for. But because engineering and coding can get a little complicated, the recommended age for independent experimentation is 13 and up. However, kids younger than 13 can certainly work on Flybrix drones with the help of their parents. In fact, it actually makes a fantastic family hobby.

Explore Two of Pompeii’s Excavated Homes in This Virtual Tour

It’s been nearly 2000 years since the eruption of Mount Vesuvius decimated Pompeii in 79 C.E., and archaeologists are still uncovering secrets about life in the ancient Roman city. As Smithsonian reports, they’ve recently excavated two homes in Regio V, a 54-acre area just north of the Pompeii Archaeological Park—and you can see the findings for yourself in a virtual tour published by the Italian Ministry of Cultural Heritage and Activities.

The 7.5-minute video comprises drone footage of the houses and surrounding ruins, along with commentary by park director Massimo Osanna that explains what exactly you’re looking at and what types of people once lived there. Osanna’s commentary is in Italian, but you can read the English translation here.

The homes, both modest private residences that probably housed middle-class families, border the Vicolo dei Balconi, or “Alley of the Balconies.” The first is fittingly named “House With the Garden” because excavators discovered that one of its larger rooms was, in fact, a garden. Excavators pinpointed the outlines of flowerbeds and even made casts of plant roots, which paleobotanists will use to try to identify what grew there. In addition to the garden and vibrant paintings that feature classic ancient deities like Venus, Adonis, and Hercules, “House With the Garden” also preserved the remains of its occupants: 11 victims, mostly women and children, who likely took shelter within the home while the men searched for a means of escape.

Across the street is “House of Orion,” named for two mosaics that depict the story of Orion, a huntsman in Greek mythology whom the gods transformed into the constellation that bears his name today.

“The owner of the house must have been greatly attracted to this myth, considering it features in two different rooms in which two different scenes of the myth are depicted,” Osanna says. “It is a small house which has proved to be an extraordinary treasure chest of art."
