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 ...

(Phys.org) —Alloys like bronze and steel have been transformational for centuries, yielding top-of-the-line machines necessary for industry. As scientists move toward nanotechnology, however, the focus ...
From methanol to formaldehyde - this reaction is the starting point for the synthesis of many everyday plastics. Using catalysts made of gold particles, formaldehyde could be produced without the environmentally ...
More than 160 researchers across 10 European countries joined together, in what is being hailed as the first international project to focus on ocean acidification and its consequences.
A three-dimensional image of one of the proteins that serves as an on-off switch as it binds to receptors on the surface of a cell suggests there may be a sort of main power switch that could be tripped. These surface receptors ...
(Phys.org) —A Purdue University-led team of researchers discovered sunlit snow to be the major source of atmospheric bromine in the Arctic, the key to unique chemical reactions that purge pollutants and ...
(Phys.org) —A sensing system developed at Cambridge is being commercialised in the UK for use in rapid, low-cost DNA sequencing, which would make the prediction and diagnosis of disease more efficient, ...
The ultrafast, ultrabright X-ray pulses of the Linac Coherent Light Source (LCLS) have enabled unprecedented views of a catalyst in action, an important step in the effort to develop cleaner and more efficient ...
(Phys.org)—The adsorption of ions in microporous materials governs the operation of technologies as diverse as water desalination, energy storage, sensing and mechanical actuation. Until now, however, researchers ...
(Phys.org)—Los Alamos researchers have developed a better technique for quick detection of live pathogens in the field. Identification of viable bacteria in a complex environment is scientifically challenging. ...
(Phys.org)—Researchers have detected the presence of a pollutant-destroying compound iodine monoxide in surprisingly high levels high above the tropical ocean, according to a new study led by the University ...
(Phys.org)—By using tiny liquid lenses that self-assemble around microscopic objects, a team from UCLA's Henry Samueli School of Engineering and Applied Science has created an optical microscopy method ...
The last time you popped a pill for a headache or a stuffy nose, did you think about how the medication actually alleviates your pain or unblocks your stuffy nose? Curing a disease is a complex process and ...
(Phys.org)—Graphene oxide has a remarkable ability to quickly remove radioactive material from contaminated water, researchers at Rice University and Lomonosov Moscow State University have found.
For several decades antimony electrodes have been used to measure the acidity/basicity – and so to determine the pH value. Unfortunately, they allow for measuring pH changes of solutions only at a certain ...
