Bwana joen kynästä: Nanoteknologia suojaa kekokanan munia mikrobeilta

Graphene, hailed as one of the thinnest, strongest and most conductive materials ever found, seems to have bagged one more amazing property. Experiments suggest that it can be used to create ultrashort laser pulses of any colour, owing to an ability to absorb light over a broad range of wavelengths.


180 nanometers diametre, 1.5 micrometers tall. Novel solar photovoltaic cells achieve record efficiency using nanoscale structures


A fourth recently-developed super-resolution technique, called structured illumination microscopy (SIM), illuminates samples with stripes of light. A computer program analyses the interference patterns formed by the stripes to reconstruct a picture of a cell at about double the resolution limit of optical microscopy. This SIM image shows a three-dimensional view of a human bone cancer cell with actin in purple, DNA in blue, and mitochondria in yellow.

For the First Time, See What the Most Basic Chemistry Actually Looks Like

OMG! First time ever photos of chemicals. 1) They look exactly like drawings in textbooks, and 2) You can actually see the bonds between the atoms. This is phenomenal!
