Science and Technology of Advanced Materials (STAM): Reported successes and failures aid hot pursuit of superconductivity
Gold rush at the initial stage of iron-based superconductors.
High Tc iron-based superconductor was reported in January 2008 via the discovery of iron- and nickel-based superconductors in 2006-2007. Half a year since then was just a dog year, i.e., the maximal Tc was pushed up to ~55K, the major parents compounds were found, and new carrier doping method ( Co substitution of Fe sites) and epitaxial thin film growth were reported. Note the received date in the figure denotes day that the submitted manuscript was received at the journal office or the manuscript was posted on ArXiv web server.

Magic wavelengths: Tuning up Rydberg atoms for quantum information applications
Rubidium atoms are held in place using a pair of laser beams at a wavelength of 1064 nm. Two other beams, promote the atoms from their ground state (5s) first to the 5p state and then to the still higher 18 s state.

Scientists control the flow of heat and light in photonic crystals
Once the laser beam hits the surface of a sample it starts to generate heat which diffuses along the membrane but also it diffuses to the ambient gas. That effect reduces the width of the temperature distribution in the photonic crystal membrane.
