81. Russian Mars Probe Crashes Back to Earth

Yet another failed mission to the red planet.

Quantum microscope for living biology

A team of Australian scientists has developed a powerful microscope using the laws of quantum mechanics to probe the inner workings of living cells. The researchers believe their microscope could lead to a better understanding of the basic components of life and eventually allow quantum mechanics to be probed at a macroscopic level.

Human hearing beats the Fourier uncertainty principle

(Phys.org)—For the first time, physicists have found that humans can discriminate a sound's frequency (related to a note's pitch) and timing (whether a note comes before or after another note) more than 10 times better than the limit imposed by the Fourier uncertainty principle. Not surprisingly, some of the subjects with the best listening precision were musicians, but even non-musicians could exceed the uncertainty limit.

First light from the first high-energy superconducting undulator

(Phys.org)—More than eight years of effort by Advanced Photon Source (APS) physicists, engineers, and technicians culminated on Jan. 21, 2013, with the production of the first X-rays from the prototype of a novel superconducting undulator (SCU), which has been installed in the APS electron accelerator and storage ring at the U.S. Department of Energy's (DOE) Argonne National Laboratory. It is the first such SCU operated at a third-generation synchrotron X-ray facility.

Elastography: New cancer detection method right around the corner; Norway and France in front

As the first countries in the world, Norway and France will be testing a completely new method for detecting cancer. This is done by measuring the elasticity of tumors. The method is called elastography. You may as well learn this new word right away; in a few years, elastography may be as common as X-rays.

Into the quantum Internet at the speed of light

Not only do optical fibers transmit information every day around the world at the speed of light, but they can also be harnessed for the transport of quantum information. Physicists now report how they have directly transferred the quantum information stored in an atom onto a particle of light. Such information could then be sent over optical fiber to a distant atom.
