Flexible Opals: 'Polymer Opals' Get Color from Internal Structure Alone
May 29, 2013 — A synthetic material which mimics the brightest and most vivid colors in nature, and changes color when twisted or stretched, has been developed. It could have important applications in the security, ... > full story -
Klein Tunneling: Coupled Particles Cross Energy Wall
May 29, 2013 — A new model demonstrates that it is possible for two particles to cross an energy barrier together, where a single particle could not. For the first time, a new kind of so-called Klein tunneling -- ... > full story -
Just How Secure Is Quantum Cryptography?
May 28, 2013 — Unlike classical encryption, quantum communication systems are known to offer the promise of virtually unbreakable encryption. Now, new research on this topic is shaking up the long-held notion that ... > full story -
How Do Plants Grow Toward the Light? Scientists Explain Mechanism Behind Phototropism
May 28, 2013 — Plants have developed a number of strategies to capture the maximum amount of sunlight through their leaves. As we know from looking at plants on a windowsill, they grow toward the sunlight to be ... > full story -
Colorado's New Alga May Be a Source of Biofuel Production
May 28, 2013 — A newly discovered strain of yellow-green algae has an ideal lipid profile for biofuel ... > full story -
Models from Big Molecules Captured in a Flash
May 28, 2013 — The structures of most of the two million proteins in the human body are still unknown, even at low resolution. A new algorithm solves the convoluted shapes of large molecules by using images of ... > full story -
'Preferred Retinal Location' May Aid Rehabilitation in Patients With Central Vision Loss
May 28, 2013 — Perceptual learning techniques may provide a useful new approach to rehabilitation in patients with central vision loss -- taking advantage of visual plasticity that persists even in old age, ... > full story -
Hydrogen Atoms Under the Magnifying Glass: Nodal Structures of Electronic States of Hydrogen Atom Directly Observed
May 27, 2013 — Researchers have succeeded in building a microscope that allows magnifying the wave function of excited electronic states of the hydrogen atom by a factor of more than 20,000, leading to a situation ... > full story -
Intelligent Street Lights Adapt to Conditions in Finland
May 27, 2013 — Researchers in Finland have developed a dimmable LED street light that consumes significantly less energy than current lighting systems, while improving the lighting characteristics. The street ... > full story -
Helicopter Light-Beams: New Tool for Quantum Optics
May 27, 2013 — A light wave oscillates perpendicular to its propagation direction -- that is what students learn in school. However, scientists in Austria have now performed atomic physics experiments with light ... > full story
