Spheres can form squares
Everybody who has tried to stack oranges in a box knows that a regular packing of spheres in a flat layer naturally leads to a hexagonal pattern, where each sphere is surrounded by six neighbours in a honeycomb-like ...

A researcher with the National Institute of Advanced Industrial Science and Technology (AIST) has developed a novel light-trapping structure to enhance optical absorption inside thin-film silicon solar cells. ...
The cellular interior is criss-crossed by protein-based cables known as microtubules, each formed from 13 'protofilaments' composed of the protein tubulin. Microtubules are also associated with a host of ...
The application of light for information processing opens up a multitude of possibilities. However, to be able to adequately use photons in circuits and sensors, materials need to have particular optical ...
(Phys.org) —Researchers at the Ames Laboratory, Iowa State University, and the University of Crete in Greece have found a new way to switch magnetism that is at least 1000 times faster than currently used ...
Many users of microwave ovens have had the frightening experience of leaving a fork, crumpled piece of aluminum foil or some other pointy metal item inside the cooking chamber. The sharp metal object acts ...
(Phys.org) —Researchers with the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory (Berkeley Lab) have once again demonstrated the incredible capabilities of metamaterials – artificial ...
(Phys.org) —Ever since their discovery in 1984, the burgeoning area of research looking at quasiperiodic structures has revealed astonishing opportunities in a number of areas of fundamental and applied ...
When a crystal is hit by an intense ultrashort light pulse, its atomic structure is set in motion. A team of scientists from the Max Planck Institute of Quantum Optics (MPQ), the Technischen Universität ...
Light is an oscillating wave of electric and magnetic fields. The way the electric field component interplays with the atoms in a material largely determines how light interacts with matter. With visible ...
(Phys.org)—A proof-of-concept device that could pave the way for on-chip optical quantum networks has been created by a group of researchers from the US.
Since the 19th century, microscopy and spectroscopy methods have illuminated many aspects of chemistry and physics, from defining atomic spectra to bringing clarity to Einstein's photoelectric effect.
The nighttime twinkling of fireflies has inspired scientists to modify a light-emitting diode (LED) so it is more than one and a half times as efficient as the original. Researchers from Belgium, France, ...
(Phys.org)—Researchers from the NIST Center for Nanoscale Science and Technology and Caltech have developed a new design platform for measuring and exploiting strong interactions between light confined ...
(Phys.org)—The investigation of ultracold molecules is of great interest for a number of problems. It could lead to a better understanding of chemical reactions in astrophysics. Ensembles of ultracold molecules ...
