Researchers in France have designed a low-frequency absorption system using metamaterials that is not only many hundreds of times smaller than standard systems, but is also claimed to totally absorb all incoming sound.

For the first time ever, a battery has been developed using sodium ions rather than lithium ions in the industry standard "18650" format used in laptop batteries, LED flashlights and the Tesla Model S, among other products.

Night-vision security cameras could be getting a lot less costly, thanks to the discovery that their lenses can be made from silicon. Ordinarily, thermal infrared camera lenses are made from materials such as germanium and chalcogenide, which are much more expensive.

In the quest to develop better ways of sealing wounds, scientists have created adhesives inspired by porcupine quills, mussels and slugs. Not all good ideas have to come from the animal kingdom, however. Recently, researchers have had success using a solution that incorporates nanoparticles.

ScienceMother-of-pearl allows mollusc shells, which otherwise consist almost entirely of brittle calcium carbonate, to stand up to the abuses of life in the sea. Now, a team of scientists has copied its structure to create a ceramic material that's almost 10 times stronger than conventional ceramics.

French researchers have produced highly conducive plastic fibers with a thickness of only a few nanometers.
-
ScienceA versatile new material reportedly combines the best properties of glass and resin.
-
ScienceScientists have created a nanoscale piston that is capable of self-assembly.

ScienceScientists have deliberately triggered electrical activity in thunderclouds for the first time using laser beams supplied by the Teramobile - a nine-ton portable terawatt and femtosecond laser which fits inside a standard six-meter freight container. Its pulses have an instantaneous power of 5 tera
