The baby cephalopods are part of the UMAMI study (short for Understanding of Microgravity on Animal-Microbe Interactions), an investigation into how the conditions of space travel impact microbiomes, the bodily flora present in all animals that play a crucial role in gut and immune health. Hawaiian bobtail squid grow up to about 3 inches long and live in shallow coastal waters. They have a symbiotic relationship with the bioluminescent bacterium Vibrio fischeri, which the squid acquire only after they’ve hatched....

The right type of light can work wonders for people whose circadian rhythms are messed with by working in (or through, as it were) space. Scientists working on Mars missions have to live on Mars time, for instance, which causes great consternation as sleep schedules constantly shift. But a recent study by Steven Lockley at Harvard University found that blue light and efficient “sleep hygiene,” as it’s known, can improve matters....

Collie sat up, dazed, and had to be helped off the field a minute later. He didn’t return to play for three weeks. The diagnosis: concussion. It wasn’t the first time Collie had suffered what’s clinically called a traumatic brain injury. On November 7, 2010, he spent nearly 10 minutes lying motionless on the 34-yard line after being hit in the head almost simultaneously by two Philadelphia Eagles players. Medics carried him off the field on a stretcher....

They are named for animals, real or mythical: the Griffon, the Jaguar, and the Serval. And they are the cornerstones of a French soldier modernization program called Scorpion (that stands for Synergie du Contact Renforcée par la Polyvalence de l’Infovalorisation), which basically means that they can operate in collaboration using a single combat information system. Launched in 2014, the program is on schedule to deliver 3,150 vehicles by 2030: 1,872 Griffons, 300 Jaguars, and 978 Servals....

One way of being economical is buying items in bulk, and there are fewer ways to score good deals than going to a warehouse club like Sam’s Club. From groceries and kitchen supplies to electronics and furniture, a membership lets you score massive savings on items you want and need. And for a limited time, new members can get a 1-year membership and a $10 e-gift card for just $14....

The new rule would release individuals and companies from being held accountable for what’s called “incidental take,” in which birds are unintentionally harmed in the course of other activities, as opposed to literally going out and shooting them. This clause has been an important tool in protecting avian species for decades. The act was passed in 1918 and was initially an effort to curb the hunting and poaching of birds for the feather trade; feathers were a major fashion accessory at the time, used to adorn women’s hats....

Some areas of the U.S. evolved with regular fires while other regions didn’t. Controlled fires are intentional and planned, while wildfires aren’t, and can damage plants and animals in the surrounding areas. This, along with other factors, makes fire management a complicated and highly political subject. Smithwick and the fire managers she worked with wanted to make sure the public understood they were trying to carry out controlled burns for the right reasons....

The theoretical particles called axions could be scientists’ best bet for explaining dark matter—the elusive stuff that makes up 85 percent of all matter in the universe that barely interacts with our “regular” matter. Two new reviews show how this particle went from runner-up to spotlight in recent years. The theories around dark matter have evolved to make these particles more convincing, the reports say. They also explore how scientists might be able to detect axions....

What are the Pioneer DJ VM-50 monitors? Pioneer DJ’s VM series is a pro-focused range that includes both the VM-50 studio monitors and the studio-grade RM-05 5-inch monitor, as well as the prosumer-leaning DM-40 and DM-40BT (a Bluetooth-enabled model) 4-inch desktop speakers. The VM Series features powered speakers, meaning they do not need an external amplifier, just a clean power source for the integrated Class D amplifier, which promises to deliver a 40Hz to 36kHz frequency response....

The statement sounds official, but it’s actually just the latest iteration of an internet chain letter that won’t do anything to protect your privacy or intellectual property from the social media networks or the wilds of the internet in general. Various versions of the message exist, but they culminate with a declaration of “Instagram does not have my permission to share photos or messages.” Unfortunately, you can type this all you want—or run and shout it out loud at a semi-crowded Dave & Busters—and it still doesn’t change the fact that you have, in fact, given Instagram and other social media services the right to share your images and more....

This moisture-wicking micro-polyester sock comes with two rechargeable 2 oz. lithium batteries, a dual charger, and a wireless remote to control the socks without bending down. And, 10 hours of battery power keep your feet warm and dry, plus a hook-and-loop closure ensures it won’t end up in the snow as you’re shoveling the driveway....

Although communication is at the core of the human experience, it’s easy to feel overwhelmed and shy away from it, dismissing it as too hard, says Adam Mastroianni, a Columbia Business School researcher who studies how people perceive each other. But having good conversations really isn’t that complicated. There are just a couple of things you’ll want to keep in mind. “Other primates do this by picking bugs out of their [community members’] hair....

Capturing rolling video is easier with a hard-wired doorbell: The constant flow of power allows the device to keep buffering footage and save it once the sensor is triggered. But without a constant flow of electricity, recording all the time becomes inefficient. Even as it improved its hardware, Ring said that adding Pre-Roll to its wireless cameras would have required weekly battery changes, which is wildly inconvenient and expensive after a while....

What It Is The Roku 3 is a tiny black square about the size of your palm. You plug an HDMI cord (not included) from your TV into the Roku, and then a power cord from the Roku into the wall. It has Ethernet and audio-out, too, though you probably won’t need them. The remote it comes with is intriguing; it’s shaped more like the old Nintendo Wii controller than anything else, and in fact it does have motion-sensing capabilities....

The occupation of Chernobyl took place during Russia’s dramatic and violent invasion of Ukraine. On Thursday afternoon, President Joe Biden addressed the country about the events. “At the very moment the United Nations Security Council was meeting to stand up for Ukraine sovereignty, to stave off invasion, Putin declared his war,” Biden said. “Within moments, missile strikes began to fall on historic cities across Ukraine; then came the air raids, followed by tanks and troops rolling in....

Multiple outlets are reporting that Samsung is planning to open a new semiconductor factory in Texas—its second in both the state and the country. Reuters and the Wall Street Journal have identified Taylor, Texas as the possible location for the estimated $17 billion plant, citing sources with knowledge of the matter. The WSJ said in January that Samsung was eyeing multiple cities throughout the United States to expand its operations....

You just need your name and email to reserve your monitor. You’ll get a $50 coupon for doing so, which will drop the price from $1,499 to $1,449 once the monitor becomes available to purchase June 6. The Samsung Odyssey Neo G8 features Quantum Mini-LED. Combined with the monitor’s Quantum HDR2000, this gives you exceptional picture quality and depth. Just think of what the tumbleweeds in Red Dead Redemption II will look like on this thing....

If a person is lost in the wilderness, they have two options. They can search for civilization, or they could make themselves easy to spot by building a fire or writing HELP in big letters. For scientists interested in the question of whether intelligent aliens exist, the options are much the same. For over 70 years, astronomers have been scanning for radio or optical signals from other civilizations in the search for extraterrestrial intelligence, called SETI....

Novices seem to be under the impression that photo editing is akin to photo manipulation, but in reality, the process is all about tweaking the image to improve its overall quality and eliminate mistakes. Think correcting colors, adjusting the brightness and contrast, and doing a bit of retouching. And for effective editing, you would need to use powerful software like Luminar. You can grab a lifetime license to the program, plus a bunch of other goodies for 82 percent off for a limited time....
