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.

Kathy Lueders, the most recent top human spaceflight official at NASA, has joined Elon Musk’s SpaceX after retiring from the agency a couple of weeks ago, CNBC has learned.

Lueders’ role will be general manager, and she will work out of the company’s “Starbase” facility in Texas, reporting directly to SpaceX president and COO Gwynne Shotwell, people familiar with the matter told CNBC.

It’s a key hire for SpaceX as the company aims to make its massive Starship rocket safe to fly people in the coming years. Lueders, a respected expert in the sector, is already familiar with the company’s human spaceflight work to date.

A commercial space station called Orbital Reef may be deployed this decade, one of many planned for low-Earth orbit.

In Part 1 looking at LEO space station deployment we focus on two front runners: the Axiom Space Station and Blue Origin’s Orbital Reef.

Dibaryons are subatomic particles composed of two baryons. Their formation, which occurs through interactions between baryons, is fundamental in big-bang nucleosynthesis, nuclear reactions including those happening within stars, and bridges the gap between nuclear physics, cosmology, and astrophysics. Fascinatingly, the strong force, responsible for the formation and the majority of the mass of nuclei, facilitates the formation of a plethora of different dibaryons with diverse quark combinations.

Nevertheless, these dibaryons are not commonly observed — the deuteron is currently the only known stable dibaryon.

To resolve this apparent dichotomy, it is essential to investigate dibaryons and baryon-baryon interactions at the fundamental level of strong interactions. In a recent publication in Physical Review Letters.

Northwestern investigators have demonstrated that fine-tuning DNA interaction strength can improve colloidal crystal engineering to enhance their use in creating an array of functional nanomaterials, according to a recent study published in ACS Nano.

Chad Mirkin, Ph.D., professor of Medicine in the Division of Hematology and Oncology, the George B. Rathmann Professor of Chemistry at Northwestern’s Weinberg College of Arts and Sciences, and director of the International Institute for Nanotechnology, was senior author of the study.

Colloidal crystal engineering with DNA involves modifying nanoparticles into programmable atom equivalents, or “PAEs,” which are used to form colloidal crystals that can then be used for designing programmable, synthetic DNA sequences.

Following up on my last posting on advances — and worries — about Artificial General Intelligence… Peter Diamandis’s latest tech blog is regarding AI and ethics.

ETH Zurich researchers have succeeded in demonstrating that quantum mechanical objects that are far apart can be much more strongly correlated with each other than is possible in conventional systems. For this experiment, they used superconducting circuits for the first time.

They are key in directing apps like ChatGPT to carry out tasks.

After a successful flight test campaign over the last two years with its two Maker aircraft, final assembly is now complete on Archer’s first Midnight aircraft and Archer is now preparing for its planned first flight this summer.
