 Nature NanotechnologyThe quantum tunneling effect leads electron transport in porphyrins The electron transport through porphyrin molecules is led by the tunneling effect described by the laws of quantum mechanics, according to an international research that has counted on the participation of a center of the Spanish Council for Scientific Research (CSIC). The article, published in the latest issue of the journal Nature Nanotechnology, dismisses the belief that this transport is via hopping between regions of the molecule. Contact: Marta del Amo

ScienceFrom a flat mirror, designer light Exploiting a novel technique called phase discontinuity, researchers at the Harvard School of Engineering and Applied Sciences (SEAS) have induced light rays to behave in a way that defies the centuries-old laws of reflection and refraction. The discovery, published this week in Science, has led to a reformulation of the mathematical laws that predict the path of a ray of light bouncing off a surface or traveling from one medium into another -- for example, from air into glass.

Nature PhotonicsManufacturing method paves way for commercially viable quantum dot-based LEDs University of Florida researchers may help resolve the public debate over America's future light source of choice: Edison's incandescent bulb or the more energy efficient compact fluorescent lamp. It could be neither.

Researchers build a tougher, lighter wind turbine blade Efforts to build larger wind turbines able to capture more energy from the air are stymied by the weight of blades. A Case Western Reserve University researcher has built a prototype blade that is substantially lighter and eight times tougher and more durable than currently used blade materials.

Advanced Functional MaterialsTiny wires change behavior at nanoscale Thin gold wires often used in high-end electronic applications are wonderfully flexible as well as conductive. But those qualities don't necessarily apply to the same wires at the nanoscale. A new study from Rice University finds gold wires less than 20 nanometers wide can become "brittle-like" under stress. It appears in the journal Advanced Functional Materials.

Sensor chip for monitoring tumors A chip implant may soon be capable of monitoring tumors that are difficult to operate on or growing slowly. Medical engineers at Technische Universitaet Muenchen have developed an electronic sensor chip that can determine the oxygen content in a patient's tissue fluid. This data can then be wirelessly transmitted to the patient's doctor to support the choice of therapy. A drop in oxygen content in tissue surrounding a tumor indicates that the tumor might be growing faster and becoming aggressive.

Floating houses Climate change is redefining the rules by which we live and at a pace we never expected. Because of rising sea level, several areas of the globe are in danger of vanishing from the map, disappearing under water. Society must adapt and maybe, one day, live in floating houses.

Nature MaterialsBerkeley Lab scientists unveil an X-ray technique called HARPES Berkeley Lab researchers led the development of a technique called HARPES, for Hard X-ray Angle-Resolved PhotoEmission Spectroscopy, that enables the study of electronic structures deep below material surfaces, including the buried layers and interfaces in nanoscale devices. This could pave the way for smaller logic elements in electronics, novel memory architectures in spintronics, and more efficient energy conversion in photovoltaic cells.

Nature NanotechnologyNew nanoscale parameter by Aalto University resolves dilemmas on silicon property The new discovery by Aalto University can have major impact on future nanoscale device design, such as ultraviolet photo detectors and drug delivery. In bulk size, many materials like silicon are as brittle as glass. In nanoparticle size, the same material can be compressed into half their size without breaking them. The new discovery was made by an international research group led by Professor Roman Nowak from Aalto University.
