Scientists create nano-size packets of genetic code aimed at brain cancer 'seed' cells

ScienceDaily.com: Nanotechnology News - 12 июля, 2018 - 17:05
In a 'proof of concept' study, scientists say they have successfully delivered nano-size packets of genetic code called microRNAs to treat human brain tumors implanted in mice. The contents of the super-small containers were designed to target cancer stem cells, a kind of cellular 'seed' that produces countless progeny and is a relentless barrier to ridding the brain of malignant cells.

Brain function partly replicated by nanomaterials

ScienceDaily.com: Nanotechnology News - 12 июля, 2018 - 17:05
Researchers have created extremely dense, random SWNT/POM network molecular neuromorphic devices, generating spontaneous spikes similar to nerve impulses of neurons. They conducted simulation calculations of the random molecular network model complexed with POM molecules, which are able to store electric charges, replicating spikes generated from the random molecular network. They also demonstrated that this molecular model would very likely become a component of reservoir computing devices. Reservoir computing is anticipated as next-generation artificial intelligence.

Hot nanoparticles produce giant and explosive bubbles

Nanowerk.com - 12 июля, 2018 - 14:00
When gold nano particles in water are illuminated by a laser, they get very hot: well above the boiling point of water. The formation of vapour bubbles caused by this, is well-known. New experiments, however, using a very high speed camera, now show that before this, a bubble is formed that is much larger and, subsequently, explodes violently.
