Phys.org / How the body senses cold has been a mystery—until now

When you reach into a bucket of ice, open your front door on a snowy day, or feel the tingle of menthol toothpaste, a protein in your nerve cells called TRPM8 springs into action, opening like a tiny gate to send a "cold" ...

Phys.org / Dancing to invisible choreography, quantum computers can balance the noise

Large-scale quantum computers are waiting in the wings. One of the main reasons we don't have them yet is because quantum hardware is so noisy. This isn't the type of noise you'd want to shush in a crowded theater. When it ...
