A new study shows how fluoride might be put to work in better batteries. Researchers at Caltech, JPL, Lawrence Berkeley National Lab and the Honda Research Institute have developed fluoride-based batteries that could potentially last much longer than existing lithium-ion-based devices.

Six years ago, we looked at the wild Romotow caravan concept from New Zealand firm W2. At the time, even W2 wasn't sure if the swing-out trailer would move beyond concept, and we didn't expect to see it again. But fast-forward to late 2018 and W2 is deep in the works building the very first model.

Electromagnetic pulse (EMP) weapons might be a staple of movies and video games, but they pose a very real threat. Sandia National Laboratories has developed a "friendly" EMP generator to make sure military and civilian equipment can withstand such potentially devastating bursts of​ energy​.

The Boring Company is edging closer to the unveiling of its very first tunnel, albeit a little behind schedule. The tunnel construction outfit announced today that it has pushed back the official opening event one week to December 18.

Maker of skateboards and rocketskates Acton also has its fingers in the electric kickscooter market, and has announced its first fleet-ready model – the M Scooter Pro – which is due for launch in January 2019.​

​It's not unheard of for outdoorsy types to have a flashlight, headlamp and bike headlight. The HeadSpin is designed to function as all three, and more, thanks to a twisting magnetic mounting system.

The Australian government yesterday passed a bill allowing law enforcement agencies to compel tech companies to hand over encrypted messaging data. The legislation has been broadly condemned with suggestions it could not only harm the Australian tech industry, but undermine encryption worldwide.

As harmful bacteria continue to become resistant to standard antibiotics, it gets increasingly important to come up with alternatives. With that in mind, scientists at MIT have looked to a species of wasp, and found an effective antibiotic in its venom.

The US Department of the Interior has announced the discovery of the largest continuous oil and gas field ever found, estimated to contain 46.3 billion barrels of oil, 281 trillion ft³ of natural gas, and 20 billion barrels of natural gas liquids.

​Nissan has confirmed the final production design for the Nissan GT-R50 and has opened the door for orders of the limited-edition supercar built with the aid of Italdesign. Apart from extra color options, there has been no change to the exterior of the car that debuted in Goodwood.

Lithium-ion batteries aren't necessarily the best choice for grid-scale energy storage. Researchers at MIT have outlined a new system they call a “sun in a box,” which stores energy as heat in molten silicon and harvests it by tapping into the bright light it emits.

Engineers from MIT and the University of Colorado have developed a new microfabrication technique and used it to produce the smallest 3D transistors ever made, measuring about a third the size of the current leading commercial products.
