The company ends the waitlist in Los Angeles, where nearly 300,000 people have expressed an interest in trying out the Alphabet-owned company’s self-driving cars.
Researchers have made a groundbreaking discovery of a neutron star in the Milky Way that rotates at an astonishing 716 times per second, placing it among the fastest-spinning stars ever observed.
The neutron star was identified using NASAs NICER X-ray telescope, which captured extreme thermonuclear bursts resembling atomic explosions. These bursts shine up to 100,000 times brighter than the Sun, providing insights into neutron stars’ life cycles and the creation of elements in the universe.

At the GlobalFoundries Technology Summit 2024, the company brought together its customers and partners from around the world. The theme was “AI Everywhere” as AI has impacted everything from IoT to the datacenter. However, the focus was on its core markets: aerospace, defense and critical infrastructure, automotive, communications and data center infrastructure, industrial IoT, and mobile devices.
RF
One key technology for many of those markets is RF (Radio Frequency) chips for mobile devices, communications infrastructure, and aerospace. GF’s mainstream RF offerings use Silicon on Insulator (SOI) wafer technology. But GF also has Silicon Germanium (SiGe) and Gallium Nitride (GaN) processes as well. With this level of diverse RF technologies, the company is well positioned for future 5G NR cellular developments and beyond, including the growth of FR2 (above 24GHz) and FR3 (7.1GH to 24GHz) bands.
As NASA plans for humans to return to the Moon and eventually explore Mars, a laser beam welding collaboration between NASA’s Marshall Space Flight Center in Huntsville, Alabama, and The Ohio State University in Columbus aims to stimulate in-space manufacturing.
A team of AI researchers with Google’s DeepMind London group has found that certain large language models (LLMs) can serve as effective mediators between groups of people with differing viewpoints regarding a given topic. The work is published in the journal Science.
Over the past several decades, political divides have become common in many countries—most have been labeled as either liberal or conservative. The advent of the internet has served as fuel, allowing people from either side to promote their opinions to a wide audience, generating anger and frustration. Unfortunately, no tools have surfaced to diffuse the tension of such a political climate. In this new effort, the team at DeepMind suggests AI tools such as LLMs may fill that gap.
To find out if LLMs could serve as effective mediators, the researchers trained LLMs called Habermas Machines (HMs) to serve as caucus mediators. As part of their training, the LLMs were taught to identify areas of overlap between viewpoints of people in opposing groups—but not to try to change anyone’s opinions.
As Canadians brace for “vitamin D winter”—months when the sun’s angle is too low to produce the vitamin in the skin—a McGill University study explains why vitamin D deficiency early in life is associated with a higher risk of autoimmune diseases.
During childhood, the thymus helps train immune cells to distinguish between the body’s own tissues and harmful invaders. A vitamin D deficiency at that stage of life causes the thymus to age more quickly, the researchers discovered.
The study is published in the journal Science Advances.
Researchers at the University of Chicago Medicine Comprehensive Cancer Center have developed a nanomedicine that increases the penetration and accumulation of chemotherapy drugs in tumor tissues and effectively kills cancer cells in mice.
The study, published in Science Advances, addresses a…
Research effectively used nanoparticles to deliver chemo drugs directly to tumors in mice.
Summary: Male worms can activate two conflicting memories—mating and starvation—when encountering the same odor, but only one influences their behavior. A study conditioned worms to associate the smell with both positive (mating) and negative (starvation) experiences, revealing that mating associations overrode avoidance behavior.
This flexible memory processing highlights how the brain prioritizes rewards over punishment under certain conditions. The findings provide insights into memory-driven behavior and offer a model for studying maladaptive processes in disorders like PTSD.
Scientists have found that a process called neurotransmitter switching—where neurons alter their chemical signals—plays a role in the development of autism-related traits.
