Scientists Gain Insight Into High-Temperature Superconductivity

by dailyfusion in The Daily Fusion

In a new study by the U.S. Department of Energy’s (DOE) Argonne National Laboratory, researchers have identified and solved at least one paradox in the behavior of high-temperature superconductors. The riddle involves a phenomenon called the “pseudogap,” a region of energy levels in which relatively few electrons are allowed to exist.... Read more »

Eyeless Fish Navigates with Mouth Suction

by Elizabeth Preston in Inkfish

As bats squeak and swoop through pitch-black Mexican caves, the pale fish that inhabit the pools below them perform a soundless imitation. These fish are blind but sense the world through subtle pressure changes on their skin. To navigate the cave floors, they also use a tool that’s never been observed in another animal: the […]The post Eyeless Fish Navigates with Mouth Suction appeared first on Inkfish.... Read more »

How to Incorporate Elusive Atoms into Nanodiamond

by Shannon Demlow in Blingtronics - Science, Engineering and Diamonds

In an article published last week in Nature Communications [1], Andrew Magyar and coworkers described a method for getting europium with a particular electronic structure into diamond. Before we examine the how let's look for a second at the why, as in, "why would you want to put europium into nanodiamond?"... Read more »

And nature does it in real-time

by Paul Stevenson in Blog of the Isotopes

A paper of mine appeared today in Physical Review E.  Called, "Extension of the continuum time-dependent Hartree-Fock method to proton states1."  As the name suggests, it is a paper about methodology - so it's not going to feature in any press-releases about exciting new physics results.  It's even an extension to an existing method (from our previous paper), which might make it seem all the less exciting.  I think it's still a good paper, and a useful one, hence the blo........
