No matter what method you use to spin—run around rapidly in circles, whirl in an office chair, or spend some time on the merry-go-round with your friends—your body reacts in the same way. When you spin around quickly, your eyes see a lot of different information in a very short time, which can be disorienting. But your body is ready for sudden changes like that, and it tries its best to keep its visual field looking normal....
“I wasn’t satisfied with the explanation that it was due to couples having more sex,” says Newcastle University’s Corry Gellatly, who did the work as part of his Ph.D. thesis. Gellatly was curious about studies of male shrimps, marine worms, and yes—human males—that showed that their likelihood of producing male offspring seemed to mimic that of their parents. In other words, males who have more brothers than sisters would in turn produce more sons than daughters....
The answer lies in the way your nose combats disease. The nose is a complex organ—it warms and modifies air as it comes into your body, and acts as a gatekeeper against the external environment, says Stella Lee, a professor of otolaryngology at the University of Pittsburgh Medical Center. That means it’s a major battleground for the immune system as it works to protect your body from invading disease. Even when you’re not sick, your nose is lined with mucus....
As of now, Antarctica remains the one continent without a high-speed fiber optic cable connection, The Verge reported. But the National Science Foundation has actively considered the idea of bridging that gap with a new undersea cable that would extend from Antarctica to either New Zealand or Australia. Undersea cables running along the seafloor function like the backbones propping up the internet. They shuttle digital information under many, many miles of ocean....
There’s an emerging third scenario, though, one positioned between those of the doomsayers and the relative optimists, and it’s the most controversial and least publicly discussed. It forecasts a world in which governments create marine sanctuaries but don’t manage to dramatically reduce carbon emissions. Scientists in this camp hypothesize that reefs of the future won’t be the same as those of today—they’ll become fewer, with fewer species—but they might just adapt and survive....
The accidents, which occured in states such as California, Florida, and Texas, collectively resulted in 17 injuries and one death, according to NHTSA. The earliest incident dates to January, 2018 and the most recent occurred this past July, in San Diego. They all involve a Tesla in Autopilot mode hitting an emergency vehicle, such as a police car. The Tesla vehicles, according to a NHTSA document, “encountered first responder scenes and subsequently struck one or more vehicles involved with those scenes....
An iteration on the iconic Predator drone airframe, the Reaper is the defining drone of the War on Terror, and saw years of action above Afghanistan, Iraq, Syria, Libya, Somalia, and Yemen. Predators, initially unarmed, were retrofitted with missiles. Reapers, building on that experience, were armed from the start. Afghanistan is landlocked, and while the other countries familiar to Reaper operators are to varying degrees coastal, much of what Reapers have been used to track are terrestrial targets....
The sheer wonderment with space has always existed with Amy Shira Teitel, who has been fascinated with space exploration since she was seven years old and was tasked with a school project on Venus. The Popular Science blogger was able to capitalize on her childhood obsession with Breaking the Chains of Gravity: The Story of Spaceflight Before NASA, a supremely interesting and well-researched look at how the origins of NASA begin well before John F....
Yet those silica gel packets are as useful as they are ubiquitous, and you can give them a second, third, or fourth life instead of sending them directly to the landfill. But why are the tiny bags in so many products? And can you reuse them? First, here’s a bit of background on the silicone dioxide-based packets. The jewelry-like silica gel beads are a desiccant, a category of materials used to keep products dry by attracting water to their surface (meaning they adsorb, not absorb, moisture)....
Four decades on, we have the answer. But COVID-19 doesn’t spell the end of the centralized office predicted by futurists since at least the 1970s. The organizational benefits of the “propinquity effect”—the tendency to develop deeper relationships with those we see most regularly—are well-established. The open-plan office will have to evolve, though, finding its true purpose as a collaborative work space augmented by remote work. If we’re smart about it, necessity might turn out to be the mother of reinvention, giving us the best of both centralized and decentralized, collaborative and private working worlds....
To explain that, we’ll have to understand what posture is in the first place. Posture generally refers to how you hold your body. Good posture, sometimes called “neutral spine,” is thought to be the optimal position that puts the least amount of stress on your body as you stand, sit, or sleep. To achieve neutral spine, your head, shoulders, and hips should all be in line vertically when viewed from the side....
The resulting graphic of the “Up Goer Five” is absurd, as it should be. But it also very clearly illustrates that, while it’s possible to describe the Up Goer Five with ten hundred words, one kind of misses the interesting nuance. Cold air for burning. This part had a very big problem once is likely an allusion to the Apollo 1 fire that killed three people 13 oxygen-tank explosion that made a lunar landing impossible....
The following morning, Knutson and four others met again. The founder of the Mill, Brian Boyle, suggested, “What about a submarine?” Within two hours, they’d drawn up the basic plans for a walk-through submarine disaster simulation game. They envisioned a player standing inside an open-ended replica of a sub’s control room, where he would extinguish threats by turning different valves or levers. Any delays would trigger a hull breach, spraying the player with water piped in from a nearby sink....
Speeds with 5G could be more than 1 gigabit per second, as AT&T recently boasted. (For comparison, a recent test of my phone’s data connection showed a download rate of about 17 megabits per second, which is about .02 gigabits per second.) But you should temper your excitement and, most importantly, save your money. This next-gen cell network is indeed coming, but it’s not here yet—and right now, unless you fit into a very specific subset of people, the costs almost certainly outweigh the benefits....

3M had been planning to make a formal announcement in a few weeks, which is why we held off talking about it. But their German division got so begeistert about the new product that they just spit out their own announcement. Images were discernable up to about 11 inches across, even under our bright fluorescent office lights. But they were definitely faded. And some movie scenes were downright indecipherable. The same went for photos....
Many parents have heard the same advice again and again—when kids are near a body of water, watch them at all times, don’t drink, and stay off your phone. But numbers show these recommendations are just not enough. “We notice things that are bright. We notice things that are loud. We notice things that move a lot,” says Graham Snyder, an emergency physician at Wake Med, who has specialized in drowning prevention for 15 years....
