As part of continuing efforts to ensure their vehicles are the safest cars on the road, Tesla’s “Bug Bounty” program gives awards to security researchers that uncover vulnerabilities in the company’s various product systems. Perhaps one of the most impressive parts of that program, however, is Tesla’s ability to remedy the flaws quickly. In the most recent example of their dedication to security, a Bug Bounty find from April this year is now being patched via an over-the-air (OTA) update in 2019.32.

Last year, a Tesla Model S key fob was hacked by a team led by Lennert Wouters of Katholieke Universiteit Leuven in Belgium (KU Leuven). The security flaw enabled would-be car thieves to clone a fob in less than two seconds, after which the vehicle could be driven off. Tesla subsequently offered a multi-part fix: PIN to Drive, a software update, and a new fob. Wouters again found a very similar flaw in the new fob, but this time the fix only required an OTA update which patched both the vehicle software and the fob’s configuration via radio waves.

A French startup is trying to streamline electric conversion with Tesla batteries in order to offer a relatively cheap way to convert older fossil fuel-powered cars.

Therefs nothing new about electric conversions, but they are often really complicated, which also makes them really expensive.

It most often cost tens of thousands of dollars, and thatfs why most electric conversions today are done on classic cars or to create drag-strip monsters.

Wow. The Chandra X-ray Observatory just celebrated its 20th anniversary of being launched into space! It roared into orbit on board the Space Shuttle Columbia on July 23, 1999.

Chandra was a revolution in X-ray astronomy. This high-energy form of light can’t penetrate Earth’s atmosphere, so you have to launch telescopes into space to see it. On top of that, you can’t easily focus X-rays, since they tend to pass right through mirrors. Awkward. So Chandra uses a set of nested, curved sheets of finely shaped metal set almost edge-on to the incoming X-rays. The photons hit the sheets at extremely low angle and graze off it like a rock skipping on water. In this way, the light is gently coaxed into moving in a different direction, so it can be focused this way.

Researchers at the University of Waterloo have developed a cheaper and more efficient method for Internet-of-Things devices to receive high-speed wireless connectivity.

With 75 billion Internet of Things (IoT) devices expected to be in place by 2025, a growing strain will be placed on requirements of wireless networks. Contemporary WiFi and won’t be enough to support the influx of IoT devices, the researchers highlighted in their new study.

Millimeter wave (mmWave), a that offers multi-gigahertz of unlicensed bandwidth—more than 200 times that allocated to today’s WiFi and cellular networks, can be used to address the looming issue. In fact, 5G networks are going to be powered by mmWave technology. However, the hardware required to use mmWave is expensive and power-hungry, which are significant deterrents to it being deployed in many IoT applications.

As vital as clean water is for human life, unfortunately it’s not always easy for people to get enough. Adding insult to injury, the stuff is basically always floating around us in the air, unreachable. Now, researchers from the University of California Berkeley have developed a device that can wring drinkable amounts of water out of even the driest air.

The team says this new water harvester can produce more than 1.3 L (5.4 US cups) of water per day per kilogram (2.2 lb) of a particular water-absorbing material. This can be done even at less than 40 percent relative humidity. That’s not a whole lot of water, but it is more than enough to keep a person alive, if a situation was that dire.

The harvester was put to the test over three days in the Mojave Desert. During that time, the device produced 0.7 L (3 cups) of water per kg of material, and even on the driest day the harvester managed to wring 200 ml (6 oz) of water out of air that had an extremely low relative humidity of just seven percent.
