Nonfriction literature
(Lehigh University) Friction and wear costs the US at least $500 billion every year. The National Science Foundation is supporting joint Lehigh-DuPont research into tribology through the GOALI Program, Grant Opportunities for Academic Liaison with Industry.

Disaster investigations, relief may benefit from explosion-sizing innovation
(American Geophysical Union) Disaster investigators and emergency personnel may find themselves better able to assess and respond to terrorist attacks and industrial accidents with the aid of a new computational tool that determines the energy from explosions near the Earth's surface.

This Slinky lookalike 'hyperlens' helps us see tiny objects
(University at Buffalo) It looks like a Slinky suspended in motion. Yet this photonics advancement -- called a metamaterial hyperlens -- doesn't climb down stairs. Instead, it improves our ability to see tiny objects.

Basel physicists develop efficient method of signal transmission from nanocomponents
(University of Basel) Physicists have developed an innovative method that could enable the efficient use of nanocomponents in electronic circuits. To achieve this, they have developed a layout in which a nanocomponent is connected to two electrical conductors, which uncouple the electrical signal in a highly efficient manner. The scientists at the Department of Physics and the Swiss Nanoscience Institute at the University of Basel have published their results in the scientific journal Nature Communications together with their colleagues from ETH Zurich.

Enhancing knowledge crucial to improving energy-saving behaviors, study shows
(University of Plymouth) Increasing public knowledge and understanding about energy issues is vital if improved energy-saving behaviors are to be encouraged among individuals and organizations, a study conducted at Plymouth University suggests.

Visualizing how radiation bombardment boosts superconductivity
(DOE/Brookhaven National Laboratory) Study shows how heavy-ion induced atomic-scale defects in iron-based superconductors 'pin' potentially disruptive quantum vortices, enabling high currents to flow unimpeded. The study opens a new way forward for designing and understanding superconductors that can operate in demanding high-current, high magnetic field applications, such as zero-energy-loss power transmission lines and energy-generating turbines.

All sounds made equal in melancholy
(Acoustical Society of America) Psychoacoustics identifies five basic types of emotional speech: angry, fearful, happy, sad and neutral. In order to fully understand what's happening with speech perception, a research team at the University of Texas at Austin studied how depressed individuals perceive these different kinds of emotional speech in multi-tonal environments. They will present their findings at the 169th ASA meeting, held this week in Pittsburgh.

From reverberating chaos to concert halls, good acoustics is culturally subjective
(Acoustical Society of America) Play a flute in Carnegie Hall, and the tone will resonate and fill the space. Play that same flute in the Grand Canyon, and the sound waves will crash against the rock walls, folding back in sonic chaos. The disparity is clear -- to the modern listener, the instrument belongs in an auditorium. 'Distinct echoes would be totally unforgivable in today's performance spaces,' says Steven J. Waller, an archaeo-acoustician. 'But, in the past, people sought echoes.'

Beyond average
(Harvard Medical School) Two separate research teams have developed high-throughput techniques to quickly, easily and inexpensively give every individual cell in a sample a unique genetic barcode.

Hubble observes one-of-a-kind star nicknamed 'Nasty'
(NASA/Goddard Space Flight Center) Astronomers using NASA's Hubble Space Telescope have uncovered surprising new clues about a hefty, rapidly aging star whose behavior has never been seen before in our Milky Way galaxy. In fact, the star is so weird that astronomers have nicknamed it 'Nasty 1,' a play on its catalog name of NaSt1. The star may represent a brief transitory stage in the evolution of extremely massive stars.
