New metamaterial-enhanced MRI technique tested on humans

Scientists from the Netherlands and Russia have designed and tested a new metasurface-based technology for enhancing the local sensitivity of MRI scanners on humans for the first time. The metasurface consists of thin resonant ...

No liquid helium, but still extremely cool

NIST scientists have devised a novel hybrid system for cooling superconducting nanowire single-photon detectors (SNSPD) – essential tools for many kinds of cutting-edge research – that is far smaller than those previously ...

High voltage for tomorrow's particle accelerator

On behalf of CERN, researchers at ETH Zurich have developed a high-tech device for the production of extremely precise, high voltage pulses that could be used in the next generation of particle accelerators.
