A glimpse inside the atom

An electron microscope can't just snap a photo like a mobile phone camera can. The ability of an electron microscope to image a structure – and how successful this imaging will be – depends on how well you understand ...

Tiny DNA 'legs' walk with record fuel efficiency

(Phys.org)—For the first time, researchers have demonstrated a DNA nanomotor that can "walk" along a track with sustainable motion. The nanomotor also has the highest fuel efficiency for any type of walking nanomotor, or ...

A 'bridge' of carbon between nerve tissues

A new material made of carbon nanotubes supports the growth of nerve fibers, bridging segregated neural explants and providing a functional re-connection. The study, which was coordinated by SISSA in Trieste, also observed ...

'Golden' silver nanoparticle looks and behaves like gold

(Phys.org)—In an act of "nano-alchemy," scientists have synthesized a silver (Ag) nanocluster that is virtually identical to a gold (Au) nanocluster. On the outside, the silver nanocluster has a golden yellow color, and ...

Electrical circuit made of gel can repair itself

(Phys.org)—Scientists have fabricated a flexible electrical circuit that, when cut into two pieces, can repair itself and fully restore its original conductivity. The circuit is made of a new gel that possesses a combination ...
