Scientists observe gravitational anomaly on Earth

Modern physics has accustomed us to strange and counterintuitive notions of reality—especially quantum physics which is famous for leaving physical objects in strange states of superposition. For example, Schrödinger's ...

Close to absolute zero, electrons exhibit their quantum nature

What would happen if an electric current no longer flowed, but trickled instead? This was the question investigated by researchers working with Christian Ast at the Max Planck Institute for Solid State Research. Their investigation ...

Nasa scientists find 'impossible' cloud on Titan—again

The puzzling appearance of an ice cloud seemingly out of thin air has prompted NASA scientists to suggest that a different process than previously thought—possibly similar to one seen over Earth's poles—could be forming ...

Quantum Criticality in life's proteins (Update)

(Phys.org)—Stuart Kauffman, from the University of Calgary, and several of his colleagues have recently published a paper on the Arxiv server titled 'Quantum Criticality at the Origins of Life'. The idea of a quantum criticality, ...

Physics explains why rock musicians prefer valve amps

For many guitarists, the rich, warm sound of an overdriven valve amp – think AC/DC's crunchy Marshall rhythm tones or Carlos Santana's singing Mesa Boogie-fuelled leads – can't be beaten.

Laser diodes versus LEDs

Solid-state lighting based on light-emitting diodes (LEDs) is the most efficient source of high color quality white light. Nevertheless, they show significant performance limitations such as the "efficiency droop". Blue laser ...
