Researchers have achieved a major breakthrough by generating quantum spin currents in graphene—without relying on bulky magnetic fields. By pairing graphene with a magnetic material, they unlocked a powerful quantum effect that allows electrons to carry information through their spins alone. This discovery could spark a new era of faster, more energy-efficient spin-based technologies.

Imagine detecting a single trillionth of a gram of a molecule—like an amino acid—using just electricity and a chip smaller than your fingernail. That’s the power of a new quantum-enabled biosensor developed at EPFL. Ditching bulky lasers, it taps into the strange world of quantum tunneling, where electrons sneak through barriers and release light in the process. This self-illuminating sensor uses a gold nanostructure to both generate and sense light, making it incredibly compact, ultra-sensitive, and perfect for rapid diagnostics or environmental testing. With its cutting-edge design, it might just revolutionize how and where we detect disease, pollutants, and more.

Scientists have developed a groundbreaking technique called RAVEN that can capture the full complexity of an ultra-intense laser pulse in a single shot—something previously thought nearly impossible. These pulses, capable of accelerating particles to near light speed, were once too fast and chaotic to measure precisely in real time. With RAVEN, researchers can now instantly “photograph” the pulse’s shape, timing, and polarization, revealing subtle distortions that could make or break high-energy experiments. This innovation has huge implications—from perfecting particle acceleration to inching closer to controlled fusion energy and probing new physics.
