Tiny electronic implants monitor brain injury, then melt away

A new class of small, thin electronic sensors can monitor temperature and pressure within the skull - crucial health parameters after a brain injury or surgery - then melt away when they are no longer needed, eliminating the need for additional surgery to remove the monitors and reducing the risk of infection and hemorrhage.

Quantum knots are real!

The very first experimental observations of knots in quantum matter have just been reported. The scientists created knotted solitary waves, or knot solitons, in the quantum-mechanical field describing a gas of superfluid atoms, also known as a Bose-Einstein condensate.

How to make a low-cost yet high-precision glass nanoengraving

Focusing the laser was conducted with the help of small glass spheres, playing the role of the lens. This mechanism allows inexpensively and relatively easy to apply complex patterns to a glass surface, whereby obtaining a spatial resolution of less than 100 nanometers.
