NASA Cassini Images May Reveal Birth of a Saturn Moon

The disturbance visible at the outer edge of Saturn's A ring in this image from NASA's Cassini spacecraft could be caused by an object replaying the birth process of icy moons.

Better solar cells, better LED light and vast optical possibilities

Changes at the atom level in nanowires offer vast possibilities for improvement of solar cells and LED light. NTNU-researchers have discovered that by tuning a small strain on single nanowires they can become more effective in LEDs and solar cells.

Virus structure inspires novel understanding of onion-like carbon nanoparticles

Symmetry is ubiquitous in the natural world. It occurs in gemstones and snowflakes and even in biology, an area typically associated with complexity and diversity. There are striking examples: the shapes of virus particles, such as those causing the common cold, are highly symmetrical and look like tiny footballs.

This image shows a virus nested within fullerene cages called carbon onions.

Scientists in Singapore develop novel ultra-fast electrical circuits using light-generated tunneling currents

Scientists in Singapore have successfully designed and fabricated electrical circuits that can operate at hundreds of terahertz frequencies, which is tens of thousands times faster than today's state-of-the-art microprocessors. This scientific breakthrough has the potential to revolutionise high-speed electronics, nanoscale opto-electronics and nonlinear optics.

A focused electron beam (in yellow) was used to characterise the structures and to probe the optical properties of two plasmonic resonators bridged by a layer of molecules with a length of 0.5 nm.
