Researchers at Keio University and the National Institute of Information and Communications Technology (NICT) in Japan have recently introduced a new design for a terahertz wave radar based on a technique known as leaky-wave coherence tomography. Their paper, published in Nature Electronics, could help to solve some of the limitations of existing wave radar.

The use of radar, particularly millimeter-wave radar, has increased significantly over the past few years, particularly in the development of smart and self-driving vehicles. The distance and angular resolutions of radar are typically limited by their bandwidth and wavelength, respectively.

Terahertz waves, which have higher frequencies and shorter wavelengths than millimeter waves, allow for the development of radar systems with a smaller footprint and higher resolution. As wavelengths become shorter, however, the attenuation resulting from wave diffraction rapidly increases.

Megaprojects like airports and transit lines are large and complex, but help is on the way.

Tesla vehicles are now confirmed to be used in Elon Musk’s Boring Company Loop project to create an electric people mover at Las Vegas’ massive convention center.

You can watch them break through the first tunnel in real time.

Opinion: Chinese carmaker Nio, the world’s newest electric vehicle unicorn, has a big idea: battery swapping. And there might be something to it.

Opinion: Forget fast-charging. Battery swapping is back—and it’s the tech of the future.

Cadillac is fully aware it needs to continue launching new vehicles that are not only relevant for the times but also offer something new. That something is — big surprise — electrification. At the moment, GM’s luxury brand does not sell an EV and its only hybrid model, the Cadillac CT6 Hybrid, is about to be discontinued. Eventually, the just-revealed 2021 Cadillac Escalade will likely offer a plug-in hybrid variant and, perhaps, an all-electric one as well. Thing is, Cadillac can’t wait that long for an Escalade EV, but it turns out an alternative is coming very soon.

GM President Mark Reuss announced last week at the automaker’s Capital Markets Day presentation the brand’s first-ever EV will debut this April. And yes, it will be a crossover, a fact that was announced a year ago at the Detroit Auto Show. Oddly, Cadillac did not preview this vehicle with a concept in the Motor City.

NASA Wallops Flight Facility is scheduled to launch a rocket tonight that will be visible to the DMV as it climbs into the sunset sky.

The facility hopes to launch the 13th Northrop Grumman resupply mission to the International Space Station (ISS) at 5:39 p.m. near sunset. The Cygnus cargo ship (spacecraft) is the S.S. Robert H. Lawrence, named for the first ever African American selected as an astronaut.

The launch and mission will be carried live by NASA.

There’s a space double feature in store for rocket fans today, with two launches to some very different places off Earth. Here’s how to watch them online.

The car can run on 60 litres of water and able to travel up to 900 kilometres (559 miles) in 10 hours. The power is generated after H₂O is split into hydrogen and oxygen which react chemically to produce energy. — Via Science and Technology.
