In 2012, Zur’s wife was diagnosed with stage IV brain cancer. At the time of the diagnosis, their son was only three years old, and Zur was afraid he would never know how wonderful his mother was. “I was very occupied with the thought he might lose his mum and will never get a chance to know her, and she’s an amazing person. I was really afraid that if I don’t do something to change it, he’ll never have a chance to know her....

According to WKYC, a legal “loophole” in Ohio currently allows that sort of use without penalty, as the news outlet found reporting on one such case earlier this year (though police said it could be considered a crime if the individual placing the device has a documented record of stalking or domestic violence). That specific instance involved an Apple AirTag, a small device that employs Bluetooth to provide real-time location updates....

It’s always wise to carry a portable battery as backup, but more often than not, you still have to deal with wires and the dreaded cable clutter. It’s better to opt for a charging solution that would make refueling less of a hassle, like the Fast Mag Wireless iPhone Charger. Equal parts functional and chic, this power bank is on sale for 59 percent off. Bring your phone to full power in style with this modern wireless charger....

Many candidates support a carbon tax… Currently, it’s free for fossil fuel companies, utilities, and other polluters to simply spew carbon dioxide, methane and other greenhouse gases into the atmosphere. A carbon tax would approximate the environmental cost of doing so, and hopefully cut down this free-for-all. Several candidates—including Senator Elizabeth Warren, former housing secretary Julián Castro, entrepreneur Andrew Yang, and Senator Kamala Harris—have noted that they would institute such a fee....

The nearly indistinguishable designations of these cars—one has a “2” in the name, the other, a “3”—and their doppelganger appearance will lead fans to wonder what exactly the difference is between them. Our efforts to answer that question while driving them on the track identified one of the cars (the GT2) as almost incomprehensibly fast on the straights, while the other rips around corners with confidence. Mat the accelerator and time slows down in the 700-horsepower GT2 RS....

Apple crisp isn’t typical fare for testing a smoker, but the Timberline—the company’s flagship pellet cooker—isn’t an average grill. It’s a high-end outdoor cooking machine with tons of features, bells, and whistles that aid in the cooking process without interfering with it. Once you get over the initial (and substantial) cost, it provides one of the most complete and enjoyable outdoor cooking experiences you’ll encounter. And, yes, it cooks the hell out of some meat, too....

So often in recent years we’ve seen storms enter the Gulf of Mexico with a giant question mark on their eventual tracks thanks to a variety of complex factors in the surrounding atmosphere, but the environment steering Gordon is pretty straightforward. A strong ridge of high pressure over the Mid-Atlantic and the Southeast will move the tropical storm directly into the northern Gulf Coast. The only real question is which communities will get the strongest winds and heaviest rain....

The Voyager 2 spacecraft, which left Earth more than 40 years ago to survey the outer planets, just detected a 5 percent uptick in these cosmic refugees, NASA announced. The new measurements bring a long-expected sign that the probe is approaching the edge of the sun’s protective influence, which for many researchers defines the line between interplanetary and interstellar space. Crossing that boundary will provide a valuable second data point in the quest to determine its shape, but precisely when the probe will leave the solar system remains unknown....

The photo is captioned with Max’s dream to become a reporter like his dad, and his desire for his first story to be an interview with the “Director of NASA.” Max wanted to “ask him about his rockets. And if any of them were going to space.” Stanton managed to set up an interview between Max and the current NASA Administrator, Charles Bolden. NASA posted a video of the interview online this morning....

Black holes are incredibly dense spots in space where the pull of gravity is so strong that even light cannot escape. Because black holes are invisible, space equipment with special tools has to help astronomers locate these forces of nature in the universe. Simulations help astronomers understand these invisible behemoths. This simulation, led by theoretical astrophysicist Taeho Ryu, a fellow at the institute, sent eight stars of different sizes and densities towards a black hole....

The exercise centered on a vehicle called THeMIS, made by Estonia’s Milrem Robotics, the company that was the lead coordinator for the 32.6 million euro (roughly $35 million) project. Alongside Estonia’s Milrem, companies in France, Finland, Spain, Germany, Latvia, and Belgium contributed to the project, with the goal of developing a “modular and scalable architecture” that could be easily modified for use alongside human-carrying vehicles. In short, the exercise was a way for soldiers to test out using many robots at once....

This mix between a drone and a traditional robot was developed by a team at Caltech’s Center for Autonomous Systems and Technologies, and its creators claim that LEO is the first robot with both multi-joint legs and propeller-based thrusters—which helps it fly and allows it to achieve a high degree of balance control. They further detailed LEO’s range of capabilities and potentials in a new paper published this week in Science Robotics....

Extreme heat like the Pacific Northwest experienced this year poses a health hazard to athletes—and can occasionally be deadly. According to experts, these weather events are becoming more common. “If climate change continues, then the frequency of extreme heat is going to rise,” says Alistair Woodward, an epidemiologist studying environmental health issues at the University of Auckland in New Zealand. “We know that even elite athletes have their limits.” As we gear up for the upcoming games in Tokyo, where record-breaking heat hospitalized more than 22,000 people in 2018, epidemiologists and other health experts are asking what the future of the summer Olympics will look like....

At the poles, snow doesn’t melt; it accumulates in layers of ice that stretch back in time like tree rings. I study particles trapped in these layers to see how climate has changed. First, my team gathers ice cores from the coldest climes. In Greenland, we traverse thousands of miles on snowmobiles to reach different collection sites, surrounded by nothing but flat, white beauty. Then we drill for samples that range from a couple hundred feet to more than a mile long and date back up to 50,000 years....

Rather than cranking up the temperatures in studios with traditional forced air systems, infrared hot yoga uses heated panels to mimic the sun’s warmth. The radiant energy warms practitioners’ bodies and the floor rather than the surrounding air. Proponents say this less swampy form of yoga offers health benefits ranging from increased flexibility to weight loss and “detoxing” the body through sweat. But as with infrared saunas (which also use this dry kind of heat), there isn’t any evidence to back up most of these claims....

To find its new Bradley, the Army is looking for an Optionally Manned Fighting Vehicle (OMFV). The request for proposal states that the new vehicle will (like the Bradley Infantry Fighting Vehicle it’s replacing), be “tasked to maneuver through the enemy’s security zone as part of a combined arms team for the purpose of creating an advantageous position, relative to the enemy, and providing protection and direct fire lethality while manned or remotely operated....

National public health agencies are kicking into gear as well. “We are standing up a formal response,” says Andrea McCollum, who leads the poxvirus epidemiology team at the Centers for Disease Control and Prevention. “At the same time this is not a public health emergency, but I do consider it to be a public health urgency.” As of this week, at least 109 cases have been confirmed, and another 86 are suspected across 18 countries, mostly in North America and Europe....

Not only would the satellite provide “a clearer view of our world,” Gore promised, but it would also offer “tremendous scientific value” by carrying into space two instruments built to study climate change: EPIC, a polychromatic imaging camera made to measure cloud reflectivity and atmospheric levels of aerosols, ozone and water vapor; and NISTAR, a radiometer. NISTAR was especially important: Out in deep space, it would do something that scientists are still unable to do today directly and continuously monitor the Earth’s albedo, or the amount of solar energy that our planet reflects into space versus the amount it absorbs....
