What if the brain came first? Scientist rethinks the Cambrian Explosion

A collaborative team of scientists has discovered that life on Earth over three billion years ago relied on the metal molybdenum, which was incredibly scarce in the environment at the time. The study, published in Nature Communications, is the first to show that molybdenum was used by ancient life this far back in our planet's history.

Photodetectors remain a critical component in the development of advanced electronics and photonics, particularly in the role of signal readout through the conversion of photons into electrons. These digital imaging components are ubiquitous in sensors, cameras, adaptive displays, telecommunications, LiDAR systems, health monitoring wearables, and oximeters.

Artificial intelligence has swept into American schools, and more is sure to come. This year, both Google and Microsoft—the two biggest companies at the forefront of the AI boom—announced major investments in AI training for teachers.

Researchers from the University of Jyväskylä, Finland, have developed a solid-phase extraction process that enables the eco-friendly recovery of critical raw materials from NdFeB magnets. The developed method utilizes organic methanesulfonic acid, which is a greener option for traditional inorganic acids. The developed process proved to be highly effective, and it was also patented.
