The most advanced new surgical procedure, AMI, addresses proprioception. This refers to the ability to sense position and movement. In an intact human arm or leg, muscles work in pairs. When a bicep ...

Neutron stars harbor some of the most extreme environments in the universe: their densities soar to several times those of atomic nuclei, and they possess some of the strongest gravitational fields of ...

When aerospace engineers talk about the future of flight, liquid hydrogen (LH2) is often part of the conversation. It is lightweight, energy-dense and carbon-free at the point of use. But storing and ...

Those that solve artificially simplified problems where quantum advantage is meaningless. Those that provide no genuine quantum advantage when all costs are properly accounted for. This critique is ...
