Bluetooth is a useful tool that you can use properly and responsibly if you only use it when you need it.

Since its IPO 15 years ago, Google has become more and more powerful. Today, that power is being highly scrutinized.

While electric vehicles are quickly proliferating throughout the world, most electric engines are still relegated to smaller vehicles. The serious work, some argue, is still done by gas guzzling diesel engines. But then there's the Elekto Dumper—the world's largest EV—which flouts the rule that EVs can't handle serious work.

Everyone uses Bluetooth. Perhaps they shouldn't. The technology that we've come to rely on to connect our phones, smart speakers, cars, vibrators, and toasters is problematic for reasons more serious than pairing issues. Bluetooth has been shown time and time again to be a security and privacy nightmare — albeit one that can be mostly solved with a simple toggling of an off switch. You just have to decide to flip that switch.

It’s a race to the skies in terms of which company actually deploys an on-demand air taxi service based around electric vertical take-off and landing aircraft. For its part, German startup Volocopter is taking another key step with the revelation of its first aircraft designed for actual commercial use, the VoloCity. The VoloCity is the fourth-generation eVTOL vehicle that Volocopter has created, but the first three were created for testing and demonstration purposes, and have flown more than 1,000 times in service of that goal.

A new investigation into the radiation levels popular smartphones give off has put some smartphone makers on the defensive. The Chicago Tribune and a team of scientists conducted studies on a variety of iPhones and Samsung Galaxy devices, including the iPhones 7, 8, 8 Plus, and X, as well as a the Galaxy S8, S9, and J3. In the testing, which also included phones from Motorola and BLU, the scientists examined whether the phones were emitting more radiation than allowed by Federal Communications Commission (FCC) guidelines.

Dell's dedicated laptop for open-source programmers sees a new release featuring Intel's hot new laptop CPU: Comet Lake.

Namita Pradhan sat at a desk in downtown Bhubaneswar, India, about 40 miles from the Bay of Bengal, staring at a video recorded in a hospital on the other side of the world. The video showed the inside of someone’s colon. Ms. Pradhan was looking for polyps, small growths in the large intestine that could lead to cancer. When she found one — they look a bit like a slimy, angry pimple — she marked it with her computer mouse and keyboard, drawing a digital circle around the tiny bulge.

Microsoft Encarta came out in 1993 and was one of the first CD-ROMs I had. It stopped shipping in 2009 on DVD.

A rash of supply chain attacks hitting open source software over the past year shows few signs of abating, following the discovery this week of two separate backdoors slipped into a dozen libraries downloaded by hundreds of thousands of server administrators. The first backdoor to come to light was in Webmin, a Web-based administration tool with more than 1 million installations. Sometime around April of last year, according to Webmin developer Jamie Cameron, someone compromised the server used to develop new versions of the program.

Fooled by gibberish and highly susceptible to human bias, automated essay-scoring systems are being increasingly adopted, a Motherboard investigation has found

FogCam will go dark at the end of August.

Recent months have seen a wave of cities and counties around the country rejecting the use of automated license plate readers in their communities, citing privacy concerns posed by the technology.

If you've ever tried to swat a fly, you know that insects react to movement extremely quickly. A newly created biologically inspired compound eye is helping scientists understand how insects use their compound eyes to sense an object and its trajectory with such speed. The compound eye could also be used with a camera to create 3-D location systems for robots, self-driving cars and unmanned aerial vehicles.

The technology is likely to revolutionize the lenses used in VR/AR headsets as well.

French researcher nets $15,000 prize for finding bugs in Moscow's Ethereum-based voting system.

Radio-frequency identification, famously used to bug the US embassy in Moscow, is a cheap way to track objects and data.

Windows is great for some things, but for many users, a Chromebook is better.

A recent study found virtual reality experiences were better at easing pain than watching televised nature scenes. Immersive distraction seems key to the success, scientists say.

Nothing is sacred
