Even Moderate Exercise Can Greatly Increase Brain Size

Lead Image: According to the study, certain regions of the brain are bigger in physically active people than in less active people. The effects are more pronounced in brain areas with high oxygen demand. Exercise keeps both the body and the mind healthy, but little is known about how and where physical exercise impacts our brains. “In previous research, the brain was usually considered as a whole,” says Fabienne Fox, neuroscientist and lead author of the current study. “Our goal was to take a more detailed look at the brain and find out which regions of the brain physical activity…

NVIDIA RTX 4000 Series Leaked, Headed To Laptops

NVIDIA’s GeForce RTX 40 “Ada” Laptop GPUs have leaked out and will include at least five variants with the RTX 4090 being the flagship. The NVIDIA GeForce RTX 40 “Ada” Laptop GPU SKUs have been leaked by REHWK who posted a chart from an OEM marketing slide listing down several next-gen SKUs. The NVIDIA GeForce RTX “Ada Lovelace” GPUs for the mobility platforms will be branded under the “GN21” series and will include at least five SKUs. These include: GeForce RTX 4090 (GN21-X11) GeForce RTX 4080 Ti (GN21-X9) GeForce RTX 4070 (GN21-X6) GeForce RTX 4060 Ti (GN21-X4) GeForce RTX 4060…

MIT Chemical Engineers Are Cracking the Carbon Removal Challenge

Lead Image: First developed at MIT, the technology enabled by Verdox enables a flow of air or flue gas (blue) containing carbon dioxide (red) to enter the system from the left. As it passes between thin battery electrode plates, carbon dioxide attaches to the charged plates while the cleaned airstream passes on through and exits at the right.

By most benchmarks, MIT chemical engineering spinoff Verdox has been enjoying…

“Something Strange Is Going On” – Physicists Answer a Decades-Old Question

Lead Image: Physicists have answered a longstanding question concerning interacting quantum particles in a disordered system. A Different Type of Chaos Physicists from the University of California, Santa Barbara, the University of Maryland, and the University of Washington have solved a long-standing physics puzzle: how do interparticle interactions impact dynamical localization? “It’s a really old question inherited from condensed matter physics,” said David Weld, an experimental physicist at UCSB with specialties in ultracold atomic physics and quantum simulation. The question falls into the category of ‘many-body’ physics, which interrogates the physical properties of a quantum system with multiple interacting parts.…

Diets High in Processed Fiber May Increase Cancer Risk

The results highlight both the need for routine blood bile acid level testing as well as caution when individuals with high bile acid levels consume fiber. The study found that men who had high fiber intake and high blood bile acid levels had a 40% higher risk of liver cancer. Fiber-enriched foods are often consumed by many individuals to promote weight loss and fend against chronic diseases like cancer and diabetes. Consuming highly refined fiber, however, may raise the risk of liver cancer in certain people, especially those with a silent vascular deformity, according to a recent study from The University…
