These Tiny Diamond Nanothreads Could Someday Support a Space Elevator

A team of scientists just strung a tone of the world's smallest diamonds into superstrong nanothreads. That makes for one impressive (and basically invisible) necklace, but the applications of these nanothreads don't end there. They could someday help string up an elevator to space—just like in science fiction. » 9/22/14 5:55pm 9/22/14 5:55pm

It Only Takes Light to Make These Nanotech Worms Wiggle

There are no shortage of surprises when it comes to nanomaterials, but this new composite is behaving in a whole new way: it wiggles when you turn on the lights. » 2/17/14 7:20pm 2/17/14 7:20pm

Laser Holograms as Thin as a Hair Could Be the Future of High-Res

Holograms are cool enough on their own, but amazing things happen when you make them incredibly small. A team of Army-funded scientists from Purdue did just that with the development of tiny holograms—smaller than the width of a human hair!—made by shining lasers through a metasurface. This could change display… » 11/15/13 5:40pm 11/15/13 5:40pm

Nanodiscs Shake Brain Cancer Into Remission

Conventional treatments are often ineffective for treating brain cancer, but scientists have developed a novel new method of destroying cancer cells in the brain: they tag them with metal nanodiscs and shake them to death with magnets. » 2/13/10 2:00pm 2/13/10 2:00pm

Nanotech Material Never Gets Wet, Even When Wet

Through the magic of nanotechnology (we use "magic" only ever so figuratively), chemists from the University of Zurich have developed a new fabric that never gets wet, even after being completely submerged in water for two months.The fabric is constructed of polyester fibers that are covered in a layer of… » 11/24/08 5:40pm 11/24/08 5:40pm

Nano Silver May Be Envionment's Silver Bullet

The UK's Royal Commission on Environmental Pollution has recently released a report urging for more study of nano-engineered materials, warning that there is a "major gap" in our knowledge of this technology. We've covered the potential dangers of carbon nanotubes » 11/13/08 10:00am 11/13/08 10:00am here before, but the commission also warns about nano…

Group Sues EPA For Not Regulating Nano-Silver Pollution

Those nano-silver socks you've been using to soak up the rank of your athlete's foot—not only are they leaching poisons into fish habitats every time you wash them, their effects on your own blood stream could be just as bad; but the EPA's not doing anything about it. Fed up by government inaction, a consumer safety… » 5/04/08 5:30pm 5/04/08 5:30pm

Nanomaterial Photos As Modern Art

Sunflowers? Nope. Actually, they're silicon oxide nanowires grown in gallium and gold catalysts — and they're only several microns in length. The photo, by Chinese University of Hong Kong professor S.K. Hark, is part of the Materials Research Society's semi-annual celebration of the most artistic and eye catching… » 4/26/08 3:00pm 4/26/08 3:00pm

British Navy Working on Developing Invisible Ships Using Metamaterials

Scientists at the Britannia Royal Navy College are working hard to make the idea of an invisible ship a reality using metamaterials that refract light in such a way that it "bends" around an object, making it appear as if it were invisible. This would only account for viewing with the naked eye however—naturally radar… » 3/03/08 8:00pm 3/03/08 8:00pm
