Seed-sized magnetic robot switches between five surgical tools in under one second

Seed-sized magnetic robot switches between five surgical tools in under one second

Researchers at Nanyang Technological University have developed a 4.4 mm magnetic surgical robot that can switch between five functions—cutting tissue, delivering drugs, collecting samples, gripping material, and generating heat—within a second. Controlled wirelessly via magnetic fields, it is designed for minimally invasive procedures in tight spaces. Early lab tests on biological tissues showed strong performance and low toxicity, and researchers are now exploring medical imaging integration for future clinical use.

Google’s AI future demands trust — and your personal data

Google’s AI future demands trust — and your personal data

Google’s AI push, highlighted at I/O 2026, centers on tools like Gemini Spark and Daily Brief that promise convenience by organizing tasks, summarizing emails, and planning your day. These features rely heavily on access to users’ personal data across Google services, giving it an edge over competitors. While useful, this deep integration raises concerns about privacy and trust, as Google’s AI increasingly depends on extensive personal information to function effectively.
