Of noise and neurons: Sensory coding, representation and short-term memory

(Phys.org)—While much is known about the limiting effect of neural noise on the fidelity of sensory coding representation, knowledge about the impact of noise in short-term memory and integrator networks has remained more ...

Physicists observe novel quantum effect that limits the number of emitted photons

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called Poisson-distribution. There are, however, light sources with non-classical ...

Why we've got the cosmological constant all wrong

(PhysOrg.com) -- Some scientists call the cosmological constant the "worst prediction of physics." And when today’s theories give an estimated value that is about 120 orders of magnitude larger than the measured value, ...

'Adaptive protein crystal' could form new kind of protective material

Chemists at UC San Diego have created an "adaptive protein crystal" with a counterintuitive and potentially useful property: When stretched in one direction, the material thickens in the perpendicular direction, rather than ...
