(Phys.org) —One of the more controversial theories of quantum gravity, which attempts to unify quantum mechanics and general relativity, is semiclassical gravity, which was proposed in the 1960s. As its name suggests, semiclassical ...
(PhysOrg.com) -- In 1983, Richard Feynman proposed the idea of a machine that could create smaller scale replicas of itself. Today, such a system is still a challenge, but a machine that can produce nanometer-sized copies ...
(Phys.org) —Frustration crops up throughout nature when conflicting constraints on a physical system compete with one another. The way nature resolves these conflicts often leads to exotic phases of matter that are poorly ...

(PhysOrg.com) -- By building a machine that uses 2,000 bouncing beads to spin a paddle and perform work, researchers from the University of Twente have finally realized a long-debated thought experiment.
An SFU-led collaboration has designed the first synthetic protein-based motor that harnesses biological reactions to fuel and propel itself.
