Tiny magnetic discs offer remote brain stimulation without transgenes

Tiny magnetic discs offer remote brain stimulation without transgenes

Novel magnetic nanodiscs could provide a much less invasive way of stimulating parts of the brain, paving the way for stimulation therapies without implants or genetic modification, MIT researchers report. The scientists envision that the tiny discs, which are about 250 nanometers across (about 1/500 the width of a human hair), would be injected directly...

10 tips and tricks to help you charge your iPhone faster

10 tips and tricks to help you charge your iPhone faster

While other smartphone makers are rapidly increasing the battery sizes and charging speeds of their devices, Apple has always been relatively conservative. Fortunately, the iPhone 16 series changed that with substantial upgrades to both. With that in mind, we’ve compiled a comprehensive guide full of tips and tricks for charging your iPhone as fast as...

Hexagonal magnetic defects could lead to energy-efficient neuromorphic computing

Hexagonal defect ASI with vortex. Credit: Communications Materials (2024). DOI: 10.1038/s43246-024-00614-0 Artificial intelligence applications are experiencing a boom and expected to be mainstream technologies in the near future. However, these applications run on classic computing hardware and are extremely power-hungry. This creates opportunities for development of new energy-efficient hardware solutions inspired by nature, e.g., brain-like...
