➀ Researchers at MIT have discovered a method to control magnetic materials using terahertz light; ➁ This creates a stable, long-lasting magnetic state in antiferromagnetic materials; ➂ The technology could revolutionize data storage and memory technologies, offering faster, more efficient, and durable solutions for next-generation electronics.

➀ MIT researchers have achieved a significant breakthrough in electronics by demonstrating the ability to 3D print resettable fuses, which are key components of active electronics typically requiring semiconductors; ➁ This breakthrough could lead to semiconductor-free electronics manufacturing, democratizing production for businesses, labs, and homes; ➂ The resettable fuses are made from a biodegradable polymer doped with copper nanoparticles, performing similarly to semiconductor transistors.

1. AI system builders are facing increasing obstacles in poaching data due to data owners insulating their databases. 2. A MIT study found that 5% of all data and 25% of high-quality data in 14,000 web domains are restricted. 3. The use of 'robots.txt' by the Robots Exclusion Protocol is limiting the data available for AI training, potentially diminishing the effectiveness of AI systems.
