En route to the optical nuclear clock

The nucleus of thorium-229 possesses a property that is unique among all known nuclides: It should be possible to excite it with ultraviolet light. To date, little has been known about the low-energy state of the Th-229 nucleus ...

Start of most sensitive search yet for dark matter axion

Thanks to low-noise superconducting quantum amplifiers invented at the University of California, Berkeley, physicists are now embarking on the most sensitive search yet for axions, one of today's top candidates for dark matter.

Dynamics of microtubules

Filamentous polymers called microtubules play vital roles in chromosome segregation and molecular transport. An LMU team has now examined how microtubule lengths vary in response to changes in the availability of their protein ...

Creating a 2-D platinum magnet

University of Groningen physicists have induced magnetism in platinum with an electric field created by a paramagnetic ionic liquid. As only the surface of the platinum is affected, this creates a switchable 2-D ferromagnet. ...

King penguin breeding colonies are structured like fluids

Colonies of breeding king penguins behave much like particles in liquids do, according to a new study by the Woods Hole Oceanographic Institution (WHOI) and international colleagues. This "liquid" organization and structure ...

Why noise can enhance sensitivity to weak signals

A team of Japanese researchers has discovered a new mechanism to explain stochastic resonance, in which sensitivity to weak signals is enhanced by noise. The finding is expected to help electronic devices become smaller and ...
