OTTAWA, May 15 (Reuters) — Automaker Stellantis (STLAM.MI) has stopped all construction at a more-than C$5 billion ($3.74 billion) electric vehicle battery manufacturing plant in Windsor, Canada, over a disagreement with the federal government about subsidies, a spokesperson for the company said on Monday.

“Effective immediately, all construction related to the battery module production on the Windsor site has stopped,” the spokesperson said.

Canada’s industry ministry did not immediately respond to a request for comment.

In San Francisco, where two major companies are testing driverless taxis, some local officials are reporting that the vehicles have caused a number of issues, including rolling into fire scenes and running over hoses. NBC News’ Jake Ward reports.

Scientists from Jilin University, the Center for High Pressure Science and Technology Advanced Research, and Skoltech have synthesized lanthanum-cerium polyhydride, a material that promises to facilitate studies of near-room-temperature superconductivity. It offers a compromise between the polyhydrides of lanthanum and cerium in terms of how much cooling and pressure it requires. This enables easier experiments, which might one day lead scientists to compounds that conduct electricity with zero resistance at ambient conditions—an engineering dream many years in the making. The study was published in Nature Communications.

One of the most intriguing unsolved questions in modern physics is: Can we make a material that conducts electricity with zero resistance (superconducts) at and ? Such a superconductor would enable power grids with unprecedented efficiency, ultrafast microchips, and electromagnets so powerful they could levitate trains or control fusion reactors.

In their search, scientists are probing multiple classes of materials, slowly nudging up the temperature they superconduct at and decreasing the they require to remain stable. One such group of materials is polyhydrides—compounds with extremely high hydrogen content. At −23°C, the current champion for is a lanthanum polyhydride with the formula LaH10. The trade-off: It requires the pressure of 1.5 million atmospheres. At the opposite end of the spectrum, cuprates are a class of materials that superconduct under normal atmospheric pressure but require —no more than −140°.

The team takes AI personalization to a whole new level.

Researchers at the School of Engineering at Princeton University have successfully deployed a large language model (LLM) to help a robotic manipulator make sense of instructions to tidy up a room.

Robotic arms, or manipulators, are great at performing assigned tasks. In a factory setup, the manipulator can assemble machine parts, paint cars and even carve sculptures. However, get one at home, and the robot is clueless. It could turn the house upside down for a simple instruction such as “tidy up the room.”

Elon Musk has been pretty open about the idea of using social media platforms like Twitter to communicate directly with customers. Tesla highlighted this in its 2022 Impact Report, with the company noting that its social media accounts have helped it reach 1 billion views on Twitter last year.

With Twitter now being owned by Elon Musk, it is no surprise that his companies like Tesla are now more active on the platform. And in a recent post, the official Tesla account asked Twitter users what it could improve. The EV community, from fans to longtime owners, responded, to a great degree. As of writing, Tesla’s post has attracted over 22k comments.

A look at the comments on Tesla’s post would show that there are numerous calls for better service. Service has been Tesla’s Achilles heel for some time now, and with the company adopting a “best service is no service” stance, some owners have reported experiencing difficulties contacting Tesla for issues with their vehicles. Comments on Tesla’s post suggest that customer service is still a key point of improvement for the company.
