After 110 Million Years, This Spider Fossil's Eyes Are All Aglow

A big, hairy spider is enough to give anyone a fright. So you can imagine what a set of eight glowing eyes attached to a body like that might do to an arachnophobe's psyche. One such spider was discovered recently by researchers, but don’t worry—the iridescent-eyed arachnid has been dead for 110 million years.

As Popular Science reports, this rare, fossilized specimen was found in South Korea’s Lower Cretaceous Jinju Formation. The find was unusual for a couple of reasons. For one, spiders are not usually preserved in rock because the soft-bodied creatures decay easily. It’s also not every day that you see a long-dead spider with glowing eyes. On top of that, researchers found two well-preserved examples of these spiders, which were described in a recent issue of the Journal of Systematic Palaeontology.

Both specimens belong to Lagonomegopidae, an extinct family that predated jumping spiders. The glow is caused by a layer of tissue called tapetum lucidum, which coats the spider’s eyes and reflects light, allowing the spider to hunt at night with ease. Many animals have it—including cats, dogs, horses, deer, raccoons, and some modern spiders—but this is the first paper to describe its existence in a fossilized spider. The tapetum is crescent-shaped and “looks a bit like a Canadian canoe,” according to Paul Selden, a geology professor at the University of Kansas and co-author of the paper.

“Because these spiders were preserved in strange silvery flecks on dark rock, what was immediately obvious was their rather large eyes brightly marked with crescentic features,” Selden said in a statement.

Researchers now want to go back and take another look at similar spiders preserved in amber, which are far more common than spiders fossilized in rock. The challenge is determining whether those specimens also have a layer of tapetum lucidum coating their eyes.

“Amber fossils are beautiful, they look wonderful, but they preserve things in a different way,” Selden said. “Now, we want to go back and look at the amber fossils and see if we can find the tapetum, which stares out at you from rock fossils but isn’t so obvious in amber ones because the mode of preservation is so different.”

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."
