Scientists discover that certain materials like silicon or gold exhibit a surprisingly large refractive index for extremely high energetic gamma-rays.

As a boy growing up in Croatia, Marin Soljacic wanted to be an inventor. But he wasn’t interested only in designing new products; he wanted to discover physical phenomena that would enable completely new technologies.

(Phys.org) -- A team of Chinese physicists has broken the distance record for teleporting qubits, extending it from 16 to 97 kilometers. They did so, as they explain in their paper uploaded to the preprint server arXiv, using the phenomenon known as entanglement.

Using tiny solar-panel-like cells surgically placed underneath the retina, scientists at the Stanford University School of Medicine have devised a system that may someday restore sight to people who have lost vision because of certain types of degenerative eye diseases.

A team of Duke University engineers has created a master "ingredient list" describing the properties of more than 2,000 compounds that might be combined to create the next generation of quantum electronics devices.

Drawing on powerful computational tools and a state-of-the-art scanning transmission electron microscope, a team of University of Wisconsin-Madison and Iowa State University materials science and engineering researchers has discovered a new nanometer-scale atomic structure in solid metallic materials known as metallic glasses.

Peter Huang of the Sensor Science Division’s Temperature and Humidity group has devised a new humidity generator that enables dew-point measurements up to 98

A mathematical model created by Aalto University (Finland) researcher Timo Ikonen explains for the first time how the DNA chains in our genome are translocated through nanopores that are only a couple of nanometres thick.

(Phys.org) -- At the heart of quantum mechanics lies the wave function, a probability function used by physicists to understand the nanoscale world. Using the wave function, physicists can calculate a system's future behavior, but only with a certain probability. This inherently probabilistic nature of quantum theory differs from the certainty with which scientists can describe the classical world, leading to a nearly century-long debate on how to interpret the wave function: does it representative objective reality or merely the subjective knowledge of an observer?

New laser-effect, discovered by scientists from the Vienna University of Technology, Princeton, Yale and ETH Zurich: If coupled, lasers can switch each other off, leading to a "laser blackout".

When stacking apples on a market stall, fruit sellers "naturally" adopt a particular arrangement: a regular pyramid with a triangular base. A French-German team, which includes in particular the Laboratoire de Physique des Solides, has demonstrated that this arrangement is favored for reasons of mechanical stability. This work, which is published on the Physical Review Letters (PRL) website, could contribute to the design of organized porous materials.

(Phys.org) -- Scientists at the U.S. Department of Energy’s Ames Laboratory have designed a method to evaluate different conductors for use in metamaterial structures, which are engineered to exhibit properties not possible in natural materials. The work was reported this month in Nature Photonics.

(Phys.org) -- New collaborative research has revealed the most efficient method to date for packing spherical objects into a cylinder. Dr Ho-Kei Chan, a Research Fellow from the Foams and Complex Systems research group at Trinity’s School of Physics, has developed an algorithm for sphere packing which finds an arrangement in which the spheres fit as densely as possible into the cylinder provided, an issue that has a broad range of applications.

Physicists have discovered a possible solution to a mystery that has long baffled researchers working to harness fusion. If confirmed by experiment, the finding could help scientists eliminate a major impediment to the development of fusion as a clean and abundant source of energy for producing electric power.
