Nanotech clothing fabric 'never gets wet'
The new fabric strongly repels water thanks to nanoscale filaments with a spiky structure (Image: University of Zurich/Wiley Vch) A jet of water sprayed onto the superhydrophobic fabric bounces out without leaving a trace (Image: University of Zurich/Wiley Vch) If you were to soak even your best raincoat underwater for two months it would be wet through at the end of the experience. But a new wate
DNA sewing machine
Japanese scientists have made a micro-sized sewing machine to sew long threads of DNA into shape. The work published in the Royal Society of Chemistry journal Lab on a Chip demonstrates a unique way to manipulate delicate DNA chains without breaking them. Scientists can diagnose genetic disorders such as Down's syndrome by using gene markers, or "probes", which bind to only highly similar chains o
Nanoscale freighter hauls its first load | New Scientist
A nanoscale “monorail” shifts cargo along a track made from a single nanotube, scale bar 300 nm(Image: Science) A nanoscale “monorail” that can creep along a nanotube track has shifted its first load, hauling a gold nugget a distance of 0.5 micrometres. The device could be a useful addition to microscopic construction toolkits that researchers hope will advance computing and other fields. The new
Nanomaterial turns radiation directly into electricity | New Scientist
New Scientist Live – Discover the exciting festival of ideas in London this September Materials that directly convert radiation into electricity could produce a new era of spacecraft and even Earth-based vehicles powered by high-powered nuclear batteries, say US researchers. Electricity is usually made using nuclear power by heating steam to rotate turbines that generate electricity. But beginning
