Researchers use AI and models to improve EV battery safety:

One of the electric vehicles’ most critical safety concerns is keeping their batteries cool, as temperature spikes can lead to dangerous consequences.

New research led by a University of Arizona doctoral student proposes a way to predict and prevent temperature spikes in the lithium-ion batteries commonly used to power such vehicles.

You know the classic game Pong with the paddles and ball that moves across the screen? Imagine the ball and paddles synchronized to music. Victor Tao approached the challenge as an optimization problem to figure out where the paddle and balls should go, based on the beats of a song:

Fortunately there is a mature field dedicated to optimizing an objective (screen utilization) with respect to variables (the locations of bounces) in the presence of constraints on those variables (physics and the beats of the song). If we write our requirements as a constrained optimization problem, we can use an off-the-shelf solver to compute optimal paddle positions instead of designing an algorithm ourselves.

What is it about human brains that enable both the regulation of bodily activities and the generation of mental thoughts? What are the mechanisms of human brain function? How do they integrate to give the sense of mental unity? What happens when something in the brain goes wrong—abnormalities, injury, disease? What is the future of brain science?

The first images are back from a spacecraft that, on Sept. 4, got to within just 102.5 miles (165 kilometers) of the surface of Mercury, the closest it will ever get. The European Space Agency’s $1.8 billion BepiColombo vehicle snapped images of the inner planet’s polar regions and cratered surface as it zoomed by.

The flyby was the seventh of its long journey around the solar system—one of Earth, two of Venus and three of Mercury—as it attempts to lose energy and steer itself into orbit around Mercury during a long and complex journey. This latest flyby reduced the spacecraft’s speed and changed its direction.

A multi-university research team co-led by University of Virginia engineering professor Gustavo K. Rohde has developed a system that can spot genetic markers of autism in brain images with 89 to 95% accuracy.

Their findings suggest doctors may one day see, classify and treat autism and related neurological conditions with this method, without having to rely on, or wait for, behavioral cues. And that means this truly personalized medicine could result in earlier interventions.

For the Artemis 3 mission, we will be able to reach astronauts up to 2 kilometers away from the lander.

COPENHAGEN, Denmark — In the never-ending quest to unlock the secrets of a long and healthy life, researchers at the University of Copenhagen have made a remarkable discovery. Their study has identified a specific gene that plays a crucial role in extending longevity across various species, including humans.

Publishing their work in the journal Cell Reports, researchers say the gene in question is called OSER1, and it encodes a protein that the team has dubbed a “novel pro-longevity factor.”

“We identified this protein that can extend longevity. It is a novel pro-longevity factor, and it is a protein that exists in various animals, such as fruit flies, nematodes, silkworms, and in humans,” says Professor Lene Juel Rasmussen, the senior author behind the study, in a media release.

China’s investment is driven by a need to secure a stable supply of chips critical to various industries, which is why over a dozen Chinese fabs are coming online in 2024 and 2025. Therefore, this surge in spending is not limited to the country’s top-tier manufacturers, such as Semiconductor Manufacturing International Corp. (SMIC) and Hua Hong, but also includes significant contributions from smaller and mid-sized chipmakers. These investments enabled China to maintain its position as the world’s largest market for chipmaking equipment. Virtually all new Chinese fabs are focused on trailing nodes, as it is hard for Chinese companies to get the advanced tools required to make chips on leading-edge process technologies.

China is the only major market to increase its spending on fab tools compared to the previous year despite a global economic slowdown. In contrast, Taiwan, South Korea, and North America all reduced their investments in wafer fab equipment during the same period.

The spending surge in China has also significantly impacted chipmaking tool makers. Companies like Applied Materials, Lam Research, KLA from the U.S., Tokyo Electron from Japan, and ASML from the Netherlands have all reported increased revenue contributions from Chinese companies. Such contributions range from 32% at Applied to 49% at ASML.
