Scientists 'squeeze' light one particle at a time

A team of scientists have measured a bizarre effect in quantum physics, in which individual particles of light are said to have been 'squeezed' - an achievement which at least one textbook had written off as hopeless.

Water heals a bioplastic (w/video)

A drop of water self-heals a multiphase polymer derived from the genetic code of squid ring teeth, which may someday extend the life of medical implants, fiber-optic cables and other hard to repair in place objects, according to an international team of researchers.

Butterfly wings help break the status quo in gas sensing

The unique properties found in the stunning iridescent wings of a tropical blue butterfly could hold the key to developing new highly selective gas detection sensors.

Waste coffee used as fuel storage

Scientists have developed a simple process to treat waste coffee grounds to allow them to store methane. The simple soak and heating process develops a carbon capture nanomaterial with the additional environmental benefits of recycling a waste product.

Growth factor-free porous films capable of promoting angiogenesis

Researchers have developed tissue adhesive porous films that promote angiogenesis (formation of new blood vessels) without using growth factors.

Nanoparticles antiparasitic to fight the common tick

Scientists designed a new external antiparasitic in the form of nanoparticles to attack the tick, which the laboratory has shown to be less toxic than the currently marketed, it does not harm the environment or the people who apply it.

Manipulating the rotational direction of artificial molecular motors using supramolecules

Researchers fabricated molecular motors on a metal substrate using supramolecules, and successfully reversed rotation of molecular motors by rearranging bonding between molecules that constitute a supramolecule.

Reversible writing with light

Self-assembling nanoparticles take their cues from their surroundings.

Hot electrons point the way to perfect light absorption

Physicists study how to achieve perfect absorption of light with the help of rough ultrathin films.
