Diseases that could have been effectively eradicated decades ago continue to ravage developing nations. In the wake of natural and manmade disasters, cholera, tuberculosis and the like spread even more easily, aided by tenuous medical infrastructures and close living quarters for refugees. Meanwhile, wealthy nations are no less imperiled, their citizens endangered by a massively consolidated food supply and by antibiotics prescribed so indiscriminately as to potentially destroy their efficacy altogether....

That finding disagrees with data from NASA’s Gravity Recovery and Climate Experiment (GRACE), two satellites which recorded Antarctica losing 92 billion tons of ice every year between 2003 and 2014. So, is it melting? Yes and no. Antarctica is a very large place and while some areas in the West are melting at alarming rates, scientists found that some areas of East Antarctica are gaining ice. One of the most recent studies about the ice gain even caused some headlines to wonder if global warming is over....

Futurist and IEEE member Heather Schlegel helps us understand why we have money in the first place,so we can see how that might change in our increasingly connected world. To take that threat further, Marla Blow, a partner at a finance investment company called Fenway Summer, envisions a world kids today might not even need to know how to swipe a credit card. And maybe paying for things will go away altogether....

Maybe I cave into my 3-year-old’s demands for sugary cereal and cookies. Or perhaps I fail to resist my own urge to snack on chocolate-covered raisins. I’m not alone. Most Americans consume more added sugar, saturated fat and sodium—and fewer servings of fruits and vegetables—than nutritionists recommend. Our diets are a major reason why about 40% of U.S. adults are obese, and run an outsized risk of developing health problems such as Type 2 diabetes and heart disease....

Smart maps Like other Roomba vacuums, the new flagship, called the i7, connects to Wi-Fi and an app, meaning that you can tap the “clean” button on your smartphone to make the robot do its job. But what sets this latest model apart is its ability to learn and remember the layout of your home (actually, multiple spaces). To do that, it relies on an imaging sensor on top of the robot that looks for patterns of light and dark around your abode so it can know where it is....

But the two companies shook hands today on an agreement to work together on a common standard for the US. As we reported a few months ago, moving your TV around poses all kinds of problems for reception. TV signals bounce off buildings and other cars, so you get dozens of reflected signals, that change constantly, confusing the decoder. You also get the Doppler effect—with waves scrunching up as you drive toward an antenna and spreading out as you drive away....

But that changed when foldable drones entered the market. These drones work just as great as their standard counterparts, but they can be collapsed to be more portable.

morsel could lead to bloating, diarrhea, gas, stomach pains, or even anaphylaxis. The jury is still out on just how many people are affected by yeast allergies or sensitivities. Back in the 80s a few doctors suggested that one in every three Americans could be suffering from a Candida albicans allergy, but that has proved to be an overestimate in recent years. Today, the yeast-free and low-yeast food movement is still very much alive....

Krause’s InAppBrowser can show you at least some of these shady tracking methods via opening the website inside an app. As he notes in his post, however, “There is no way for us to know the full details on what kind of data each in-app browser collects, or how or if the data is being transferred or used… [InAppBrowser] is stating the JavaScript commands that get executed by each app, as well as describing what effect each of those commands might have....

What is the Sennheiser IE 900? First and foremost, the Sennheiser IE 900 is indulgent. If you think $1,299.95 is an obscene amount to pay for a single piece of audio gear, stop reading. No judgement. At the same time, the IE 900 is far from the most indulgent personal audio item you could buy; actually, it’s only upper mid-tier considering how many multiple-thousands you can spend on a pair of summit-fi IEMs or headphones....

Originally built for Russia’s Tu-22 Blinder supersonic bomber, the R-23 gun was mounted in the plane’s tail as a deadly surprise for any pursuing jet fighters. The gas-powered gun could fire 23mm rounds incredibly quickly. It’s a variant of this gun that made it to space, on board one of the Soviet Union’s Almaz military reconnaissance space stations. From Anatoly Zak, writing at Popular Mechanics: Read the full story there, and be sure to check out the painstakingly rendered images of the gun itself....

This year’s historic flights include missions to Jupiter and the asteroid belt, robotic moon landings, and the maiden flight of a new spacecraft to take astronauts to and from the aging International Space Station (ISS). Here are some of the major launches to look forward to in 2023. Asteroids and icy moons Both NASA and the European Space Agency (ESA) have big plans for studying celestial bodies beyond the orbit of Mars that kick off in 2023....

That’s the message that NASA and the American Society of Mechanical Engineers (ASME) Foundation are sending to enterprising young inventors across America, as part of the new Star Trek Replicator Challenge. The challenge, which was officially announced today at New York’s Intrepid Air and Space Museum (the one on a retired aircraft carrier), asks kids in grades K-12 to create 3D models of non-edible, food-related items (i.e. knives, flatware, food storage/disposal devices, etc....
