After a pair of millipedes started getting it on, researchers from the Field Museum of Natural History in Chicago scanned both individuals and one male-female pair in an electron microscope. They also captured dozens of photos at slightly varying angles on a digital camera. By layering them digitally, they were able to clarify tiny genital details. They photographed the millipedes in both natural and ultraviolet lights, since their genitals glow under UV lighting....

Expect to see results in the U.S., Australia, and Israel, where the joint team has set up eco-architecture projects to create civic amenities, including playgrounds, hospital benches, street lamps, and gates. Instead of shaping trees grown in soil and water to form these structures, the team will grow trees in the air, to create malleable “soft roots.” This patented engineering technique will make it easier to build larger structures. How large?...

The Zone is, in many respects, a first for Dyson. It is the company’s first wearable product. It is also the company’s first product primarily made for outdoor use. The motors, which you can see running in the center of each ear cup, are the smallest that Dyson’s ever produced. Though the device seems quite large compared to an average pair of Bluetooth headphones, every millimeter of the device is packed to the gills with tech....

Congress passed a bill called the CHIPS and Science Act on July 28th to boost domestic semiconductor production and fund scientific research. The Senate also just passed an expansive bill called the Inflation Reduction Act (IRA). Both bills would do quite a bit to help the US fight climate change—much to the relief of many Democrats in Congress worried about getting climate legislation passed before the midterms. But with so much legislation floating around, keeping track of each bill’s actions can be tricky....

Modern fuel injection is amazing, but before injectors, ECUs, and fuel pumps motorcycles used carburetors. Some smaller bikes and two-strokes still do. Today on MC Garage we talk about the carburetor. For those of you who have an older motorcycle model or a modern two-stroke, one of the most confusing and intimidating tasks is probably jetting the carburetor correctly. To some, it amounts to black magic. But if you know the theory and reasons for each circuit in your Mikuni, Keihin, or Lectron and you take it step by step, it’s really not too difficult....

“If we can figure out what virus is the trigger, that’s how we develop vaccines,” says Priya Duggal, director of the genetic epidemiology program at the Johns Hopkins Bloomberg School of Public Health. Researchers also need to figure out how the virus works. “If we fail to understand the mechanism, history will repeat itself. Another virus will come up.” Viruses called non-polio enteroviruses are the lead suspects for causing AFM....

Understanding nutrient deficiencies in plants Just like us, plants need nutrients to carry out functions like growing and reproducing. If they don’t have enough, they may survive, but they won’t thrive. Undernourished plants may face stunted growth, deformation, or reduced chlorophyll production, which explains signs like yellowing and curling leaves. Knowing how to read these signs will allow you to help your plants by providing proper and timely care. But first, you’ll have some diagnosing to do....

But despite their similarities, these displays serve two different purposes, and some key differences can result in a monitor beating a television, and vice versa depending on the context. If you want to get the best possible output and picture from whatever device you’re connecting to your screen, know that both will do the job to a certain extent—but only one is better than the other. To choose the right one for the job, you’ll need to familiarize yourself with the pros and cons of each type of display....

Sure, there’s inexpensive summer rosé or pinot grigio you might throw back with some ice or even seltzer, but what about those more subtle, complex bottles? You don’t want to drink an expensive vintage you’ve been saving for your anniversary at a temp that doesn’t do it justice. Nor do you want to regularly be drinking your casual evening cabernet too warm. Here are some of our favorite wine refrigerators to help you get the best out of every bottle....

The conventional viewpoint is that the first terrestrial life migrated out of the water about 430 million years ago, in the midst of a period known as the “Cambrian Explosion of Life”–an evolutionary heyday when favorable conditions allowed life to swell and branch into most of the major forms in existence today. During this time, the theory goes, a group of freshwater plants inched their way onto muddy shores and into swamps and watery lowlands, and true land plants evolved from there....

Pfizer’s vaccine for children between the ages of 5 and 11 is likely to be approved by the CDC as early as next week, and based on historical patterns, Moderna’s will probably follow a few weeks later. And vaccines for toddlers and really young kids are just over the horizon. Pfizer spokesperson told PopSci over email that the company’s data on six-month to five-year-olds could come before the end of December....

Today, the generally accepted explanation is “stellar scintillation.” Lorne Whitehead, a physicist at the University of British Columbia, describes it like this: A bright light, positioned far away, projects as a tiny point through the varying air densities of our atmosphere. Hundreds of these pockets act as lenses, refracting the light so that it moves like the light on the bottom of a swimming pool on a sunny day. The changing swells on the pool’s surface correspond to the turbulent shifting of our atmosphere....

Why are we so unprepared for these disasters, and what can we do to protect ourselves from them in the future? The answer lies as much in the built environment as in the atmosphere. The cityscapes and towns we live in were designed for an era of weaker and more predictable weather, and now, as warming ratchets up Mother Nature’s intensity, the artificial infrastructure around us is falling apart at the seams....

The vulnerability—catchily called CVE-2022-3075—was only brought to Google’s attention on August 30 by an anonymous security researcher. That the company pushed an emergency security update on September 2 speaks volumes about the severity of the underlying issue. The previous update—coincidentally released on August 30—patched 24 security issues including a different critical zero-day, so it is a big deal that Google felt the need to release an update to address a single vulnerability immediately....

Church and his colleagues are combating two of the biggest reasons why pig organ transplants haven’t worked in humans. First, transplants from pigs are more likely to infect the human recipient with nasty viruses which are incorporated in its genetic code. So the researchers have modified 62 of those genes in pig embryos—that’s more than ten times the number of genes that have ever been edited in any other animal, as Nature News reports....

“You can’t drive down the avenue without seeing 10 or 20 people just openly injecting,” says Bill Kinkle, a former opioid user now two years clean. He walks to work along this road, stopping to see if those sprawled out are breathing or turning blue—both signs of an overdose. He keeps multiple doses of naloxone—an overdose reversing medication—on him at all times. While Kinkle was born and raised in Kensington, his family recently moved to a nearby suburb due to crime in the area....

In the study, 24 workers spent six days working in an environmentally controlled office (the days studied were all in the middle of the week in order to eliminate “the concern about known mental effects of Mondays and Fridays,” as Ars Technica reports). Each day the researchers changed the level of carbon dioxide and volatile organic compounds, which can enter conventional workspaces through things like leaky furnaces and furniture, flooring, air fresheners, or paint respectively....

The Powerwall’s large curvy case is the size of a futuristic boogie board, and it’s meant to be mounted on a wall like art. It draws electricity from the grid when demand and rates are low or sucks it from solar panels atop your roof (panels sold separately). The energy is saved for use during peak power-demand hours, when utilities raise rates, or as backup during a power outage. It fits in nicely with another Musk-backed company: SolarCity....

Since then, Facebook has endured a litany of scandals regarding privacy. Photos were exposed to people who shouldn’t have been able to see them, and leaked documents reportedly showed that Facebook was leveraging user data with other large companies to generate revenue. Mark Zuckerberg testified in front of Congress and Facebook as a company lost considerable sums of value from a combination of factors. It was a bad year for privacy on Facebook....

But if we’re being honest, is taking a supplement you bought at the drug store any smarter? The bottles don’t say “swallow me,” but they might as well. Instead they’re emblazoned with promises. The yellow ones will make you stronger. Red will increase your energy levels. Purple will heal your scars. It’s a veritable rainbow of cures. They offer quick and easy solutions in a way that medicine can’t—because medicine is bound by evidence....
