According to a new test for "quantum-ness," birds probably rely on quantum mechanics to sense magnetic fields. But photosynthesis and vision could work without it, albeit less efficiently.
A new formalism determines whether quantum-mechanical effects are necessary for photoactivated biological processes to occur.

Martin, no entiendo lo que quiere decir esa cita de Schrodinger.  Me lo puede explicar un poco?

The Fermi-Hubbard model is an extremely crude theoretical description of electrons in a metal, but it has been successful at explaining some phenomena. Now experiments show that two atoms bouncing between a pair of adjacent optical traps follow the Fermi-Hubbard predictions, which could lead to more complete testing of this widely-used model.
A simple system consisting of a pair of atoms in a two-site “minicrystal” is able to reproduce the physics of a widely used model of electrons in a solid.

General relativity says that the gravitational pull of a massive object like the sun deflects the path of a passing photon. But the predictions of a quantum mechanical gravity theory could be different. Now theorists have calculated the tiny difference between the two theories' predictions.
Theorists calculate how quantum gravity effects could alter the bending of light induced by massive objects.

but have they verified it experimentally the way Einstein's theory was?

Using a set of interactions between DNA strands, proteins, and single DNA "letters," researchers have come up with a new tool box for chemical reactions. They can completely control the shape and speed of a reaction front as it advances through a medium.
Strands of DNA can be used to generate waves of chemical reactions with programmable shape and velocity.

A cold atom interferometer uses the wave nature of quantum particles to make sensitive measurements. This improved design measured the Earth's rotation rate to an accuracy of 1% and could lead to a portable device with world-class sensitivity.
An improved cold atom gyroscope could lead to portable, ultraprecise devices for navigation and tests of fundamental physics.

The Casimir effect is a quantum mechanical phenomenon where two closely-spaced metal plates attract one another due to the "virtual" photons that constantly appear and disappear everywhere in space. It comes from the quantum nature of the electromagnetic field. Now a theorist derives an analogous effect that should exist if gravity also has a quantum nature.
Evidence that gravitational waves induce an attractive force between two closely spaced mirrors could confirm gravity’s quantum nature.

The nucleus of a cell must be well-centered when it's time to divide, but the centering process isn't fully understood. Now it appears that motor proteins are the mysterious components that adjust the lengths of stiff biopolymers connecting the nucleus to the cell membrane.
A motor protein called kinesin-8 helps keep a cell’s nucleus centered by controlling the length of the tubular structures that connect it with the cell wall.

Where has all the antimatter gone? This is one of the top questions in all of physics. A new theory to explain the scarcity of antimatter relies on a Higgs field whose value varied with time shortly after the big bang. The theory requires just one new, unobserved particle, a so-called heavy Majorana neutrino.
A new explanation for why matter dominates in our Universe rests on the idea that the Higgs field hasn’t been constant in time.

Physicists at the Large Hadron Collider discovered two new proton-like particles. Each contains three quarks, one from each quark family, and each is about six times as heavy as a proton. The detections will lead to tighter constraints on future particle physics theories.
Researchers report the detection of two new subatomic particles made of three quarks from each of the possible quark families.

Diamonds provide two new tricks for quantum computers:
1. Memory: storing single photon bits in the form of lattice vibrations at room temperature.
2. Quantum communication amplifier: a photon can be entangled with the spin of a so-called nitrogen-vacancy defect in the crystal, which could faithfully store and transmit quantum information.
Diamond crystals enable new ways of storing single photons at room temperature and detecting their entanglement.

Working to advance and diffuse the knowledge of physics
Introduction
The American Physical Society (APS) is a non-profit membership organization working to advance and diffuse the knowledge of physics through its outstanding research journals, scientific meetings, and education, outreach, advocacy and international activities. APS represents more than 50,000 members, including physicists in academia, national laboratories and industry in the United States and throughout the world. Society offices are located in College Park, Maryland (Headquarters), Ridge, New York, and Washington, DC.
