For National Fire Prevention Week, we bring you fire safety tips and technology courtesy of PopSci writers and fire enthusiasts past. Be careful about that watch you’re wearing–it could erupt into flames! _ See the gallery._

When Roswell Schaeffer Sr. was 8 years old, his father decided it was about time he started learning to hunt beluga whales. Schaeffer was an Iñupiaq kid growing up in Kotzebue, a small city in northwest Alaska, where a healthy store of beluga meat was part of making it through the winter. Each summer, thousands of these small white whales migrated to Kotzebue Sound, and hunts were an annual tradition....

Like other manufacturers, Audi has also been testing on public streets and highways where it’s been licensed to do so, such as in Nevada. But an autonomous car has to be able to both read stop signs in slow-speed neighborhoods and navigate turns on high-speed roads. The system will be incorporated into the next-generation Audi A8 “in a few years,” according to a press release. That’s in line with the timelines for automated (but not entirely self-driving) vehicles from other manufacturers....

Sleepy octopuses shift colors while snoozing Octopuses and other cephalopods are known masters of deception. Scientists have seen them camouflage into the seabed in the blink of an eye. Now, we know that an octopus’s color can even change while the creature slumbers. In March, scientists studied whether octopuses undergo “active” sleep, or R.E.M sleep, like humans do. As it turns out, they experience very striking changes as they shift between such states....

By making Arduino an open-source platform, the Institute made the technology freely available to anyone, which led to a vast array of starter kits.

We’re not knocking all built-in speakers; some computer brands deliver adequate, if not high, fidelity. Even the most expensive PC could use a strong audio boost, though. External speakers that connect to your devices either through input and output jacks, a USB port, or Bluetooth pairing will give you the rich surround sound we once demanded from our home stereo systems back in the days of CDs and mixtapes. There are a lot of options to go through, but the effort to find the best computer speakers will be worth it when you’re upgrading from sound that’s transistor-radio quality to audio that can fill your entire home....

The best patio furniture creates an outdoor oasis Shopping for the best patio furniture is an exciting time. Think of your outdoor space as an extension of your indoor space, decor-wise. Once you’ve set it up to your liking, though, be warned: Neighbors, friends, and family won’t be able to stay away. Whether you want patio dining furniture or patio lounge furniture, prefer vintage wicker patio furniture or rustic wrought iron furniture, there are plenty of options....

Beyond that, choosing the best gardening bench—something of a misnomer, because it’s more table than bench—comes down to your particular needs. Do you want something with a removable dry sink, so you have a place to mix soil neatly? What about wheels, to move the plant bench around? Are you a sucker for heavy metal, or would you prefer something whittled out of wood? And would you like something that folds up neatly so it can be stowed in the garage or shed during colder months or inclement weather?...

It’s important to know when you need new shoes for running. Experts suggest springing for a new pair every 300 to 500 miles. For those who are good with long distances only when running them, that averages to a switch about every four to six months, if you run 20 miles a week. Those of us who are a little laxer on our running schedules can wait to snag a new pair....

“‘Would you like to be the second human being to see potentially the most distant galaxy ever known?’” Naidu recalls asking her. She looked, found it “a bit underwhelming,” he says, and went back to watching TV. “But she’s come around,” he says with a laugh. The galaxy candidate in question, GLASS-z13, doesn’t look like much to the untrained eye. Just a red splotch of light. But that unassuming visual is precisely why GLASS-z13 captured Naidu’s attention....

The massive population explosion is big enough to see from space, and NASA’s Aqua satellite captured this image with the Moderate Resolution Imaging Spectroradiometer (MODIS) earlier this month. The blooms usually die down by May, so this might be one of the last swirly-marine-life photos we get this year. NASA
