Slinky-like 'Hyperlens' Enables Observation of Single Molecules

May 25, 2015 7:00 am | by Univ. at Buffalo | News | Comments

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. The hyperlens may someday help detect some of the most lethal forms of cancer.

Atomic-level 'Flyovers' Show How Radiation Boosts Superconductivity

May 25, 2015 7:00 am | by Brookhaven National Laboratory | News | Comments

Sometimes a little damage can do a lot of good— at least in the case of iron-based high-temperature superconductors. Bombarding these materials with high-energy heavy ions introduces nanometer-scale damage tracks that can enhance the materials' ability to carry high current with no energy loss— and without lowering the critical operating temperature.

Super Balls Are Physicists' Favorite Toys

May 25, 2015 7:00 am | by Inside Science News Service, Joel Shurkin | News | Comments

Super Balls are toys beloved by children because of their extraordinary ability to bounce. Physicists love them for exactly the same reason. Drop a baseball on the floor and it will hardly bounce at all. Drop a Super Ball from shoulder height, and it will bounce back 92 percent of the way to the drop-off point.

Good Sound Quality Definition Differs by Culture

May 22, 2015 1:30 pm | by Acoustical Society of America | News | Comments

Play a flute in Carnegie Hall, and the tone will resonate and fill the space. Play in in the Grand Canyon, and the sound will crash against the rock walls. The disparity is clear— to the modern listener, the instrument belongs in an auditorium. But, in the past, people sought echoes. The response of audiences and performers to acoustic characteristics is a function of their worldview, and it is as fluid as the environment they inhabit.
