Pectin is found naturally occurring in various forms of plant life, where it helps to bind cells together. In spite of the fact that it is widely occurring, there are only a few specific sources used to manufacture pectin for food purposes. Traditionally apple peels and cores were the primary source of pectin for making jellies and preserves. The liquid extract was preserved with sulfur dioxide and sold in bulk....
You may wonder why would you want to play your video games on a computer, but the answer is simple: you’ll be able to play on your PS4 when you’re away from home by using your laptop. Or if you’re home but you have to compete for TV time, you can enjoy an Xbox-powered Minecraft session on your laptop while your kids watch Paw Patrol on the big screen. Just keep in mind that you’re only streaming content from one device to another, so you can’t play one game on the console and another on your laptop....
Now scientists suspect that miniature versions of those icy mountains have drifted out onto the wide, flat plains of the area known as Sputnik Planum, located in Pluto’s heart-shaped region. As a NASA press release today explains: Some of the icy hills form chains that stretch up to 12 miles across. Although finding more water ice anywhere else in the universe is exciting, it probably doesn’t raise Pluto’s changes for life — the planet is still likely too distant and thus likely too cold to support liquid water or any associated lifeforms....
However, new research suggests the situation may not be quite so grim. Linda Gormezano and Robert Rockwell from the American Museum of Natural History (AMNH) posit that polar bears may be able to fulfill energy needs by feeding on caribou and snow geese instead. In fact, they’re already starting to do so. Rather than waiting around to starve, the bears are trying to adapt. During the late spring and summer months when the ice pack naturally starts to recede, there have always been polar bear populations that experience a couple of ice-free months–times when the the ice is too far out to sea to go and hunt seals in their ice lairs....

Grand Award Winner: A ‘cookie jar’ that one-ups online trackers Cookies make the internet work a little more smoothly by remembering a user’s browsing habits, but when the data trackers follow individuals across different sites, a useful tool becomes a privacy liability. Firefox, the browser by Mozilla, introduced an optional feature called “Total Cookie Protection,” which in a meaningful way limits the trails of crumbs you leave behind online....
Whether or not it makes environmental sense to inflate car tires with nitrogen instead of air is a matter of debate. Proponents of nitrogen say the element is a smart choice for the environment primarily because it leaks from tires at a slower rate than air, so tires stay inflated longer at full capacity, which helps a vehicle attain maximum fuel efficiency. According to the Get Nitrogen Institute, a Denver-based non-profit which advocates for replacing the air in our tires with nitrogen, under-inflated tires are a big contributor to global warming, as they cause cars to waste fuel....
All too often, even in 2022, Black students are interpreted through a deficit model: Academic institutions assume that we’re underprepared and that our families are unfamiliar with such work. Read Carolyn Beatrice Parker’s CV in the context of her family’s achievements, however, and it’s immediately apparent that she represents an example of what’s possible when intellectual success is expected and the resources to achieve it are provided. Parker, the first known Black woman to earn a master’s degree in physics, came from a family of strivers who could arguably be held up as the archetype of W....
Small robots have a tough time traversing rocky terrain, so engineers Dario Floreano and Mirko Kovac of the Laboratory of Intelligent Systems in Lausanne looked to nature for a solution. Grasshoppers and locusts, they noticed, can quickly cover up to three feet of uneven ground in a single hop, much quicker than they could by walking (or, as is the case for most robots, rolling). So the researchers built a batch of microbots that can propel themselves eight feet into the air—10 times as high as other ‘bots their size—using two spring-loaded feet powered by the same type of motor that vibrates your cellphone....
In the heart of Europe, along the French-Swiss border, the particle physics laboratory at CERN is facing the same plight. This month, it’s been reported that CERN officials are drawing up plans to limit or even shut down the recently rebooted Large Hadron Collider (LHC). If the LHC, the largest and most expensive collider in the world, does shut down for a short stint, it wouldn’t be out of the ordinary for particle accelerator research....
It turns out that the Galaxy Buds2’s new design creates an extremely comfortable fit, leaves room for ample battery life, and enables a whole host of connectivity features. Like AirPods, many of the Buds2’s most interesting features only work with modern Samsung Galaxy devices, which limits their wider utility. That said, they sound great on any device, with very clear, strong bass that delivers body without overpowering your favorite songs or movies....

The Goal Zero Yeti Core earned a spot on our list of the best solar generators as the camping pick. Yeti has earned its burly reputation for some of the most rugged power products available on the market and this backup system is no exception. It stores 983Wh of power and weighs just under 32 pounds, which is considerably less than other electric options, let alone gas-powered models. Plug the included 120-watt power supply into any 8-millimeter charging port to recharge the Yeti in 9 hours (or add a 230-watt power supply to half the recharge time)....
The number one culprit to disorganized desks continues to be paper. And the second? It’s most probably cables and chargers. With the number of electronic devices we depend on to function at work, we also accumulate tons of wires and adapters to keep them charged throughout the day. This often leads to cable clutter that can be both an eyesore and a nuisance to your workspace. To combat this, you may want to switch to a wireless charger to accommodate your Qi-enabled devices....

The Samsung QN90A NEO QLED TV uses Mini-LED technology to brighten and dim in the right areas, meaning you won’t have to worry about squinting during a dark Game of Thrones episode or J.J. Abrams lens flare. AI-based deep learning tech analyzes the incoming signal, source, and scene to optimize what happens on-screen. If 75-inches is too large—or not large enough—for your space, the television also comes in 65-inch and 85-inch varieties....
The essential building material comprises water, coarse aggregates, like sand and gravel, and a binding agent—which is where cement, an especially carbon emissions heavy product, comes in. According to the International Energy Agency, the cement sector is the third-largest industrial energy consumer in the world, consuming seven percent of industrial energy use. It is also the second-largest industrial emitter of carbon dioxide, responsible for seven percent of global emissions. Most emissions occur when raw materials, typically clay and limestone, are heated to more than 2500 degrees Fahrenheit to become the super-strong binding material....
The coronavirus has ground social, economic and educational exchanges to a halt around the world. For now, public health officials are relying on tools like social distancing to minimize the harm of the virus, but in the long term, a COVID-19 vaccine is the best hope of a return to normalcy. It normally takes a few years to development a vaccine, but in the face of the coronavirus, biotechnology companies and regulatory agencies are taking aggressive steps to make a COVID-19 vaccine widely available sooner than that....
So chimpanzees are rightly known as resourceful eaters. But until now scientists had never observed them eating reptiles. That has all changed, thanks to a group of wild chimpanzees in Loango National Park along the Atlantic coast of Gabon in Central Africa. These chimps have recently become used to the presence of humans, which means scientists can now see them act exactly as they would in nature. And, writing in the journal Scientific Reports, a group of researchers say they have already observed behavior not previously seen in chimpanzees....
But there’s another greenhouse gas, methane, that some scientists argue is low-hanging fruit among the many strategies to stabilize our climate. In a surprising and counterintuitive proposal published Monday in the journal Nature Sustainability, Stanford University scientists argue that we can limit warming by chemically converting methane to carbon dioxide. “Our paper is a call to view methane removal as an opportunity,” says Rob Jackson, the study’s lead author. Methane, or CH4, is currently concentrated in the air at 1,860 parts per billion, about two and a half times the amount there was before the Industrial Revolution....
