Amazon has appointed longtime AWS leader Peter DeSantis to lead a new AI-focused division aimed at advancing its AI models, silicon technology, and quantum computing efforts. This move reflects Amazon’s growing commitment to AI innovation and infrastructure investments.

MIT scientists have created an advanced AI model that can identify and quantify atomic defects in materials, a breakthrough for improving products like semiconductors, solar cells, and batteries. Leveraging data from noninvasive neutron-scattering, their system can pinpoint up to six types of defects at once, covering a broad range of materials. This approach could lead to greater control over material properties, though there are still challenges integrating it into existing manufacturing workflows.

As AI-generated media and restricted satellite imagery spread online, traditional ways to verify digital content are faltering. The rise of fast-moving synthetic information—often indistinguishable from real events—means audiences must rely more on careful checks and skepticism. Until more robust tools emerge, the best defense is to pause and question before sharing.
