Quantum Teleportation Achieved Over Busy Internet Cables for the First Time

Northwestern University engineers have achieved a breakthrough by successfully demonstrating quantum teleportation over a fiber optic cable already carrying internet traffic. This discovery, published in Optica, opens the door to integrating quantum communication with existing internet infrastructure, significantly simplifying the requirements for advanced sensing and quantum computing applications. The team cleverly navigated the challenge of entangled photons interfering with dense internet traffic by selecting an optimal wavelength and employing special filters. This successful transmission paves the way for next-generation quantum and classical networks sharing a unified fiber optic infrastructure, promising a future of more accessible quantum technologies.

Metformin's Secret Revealed: Mitochondria Hold the Key

A new study unveils the precise mechanism of action for metformin, a widely used drug for Type 2 diabetes. Researchers discovered that metformin lowers blood sugar by interfering with mitochondria, the cell's powerhouses. Specifically, it blocks mitochondrial complex I, a crucial part of the cell's energy-producing machinery. This research, published in Science Advances, used genetically engineered mice to demonstrate that metformin targets disease-contributing cells without significantly harming healthy ones. This provides a deeper understanding of how this 'wonder drug' works.
