The development of technologies which can process information based on the laws of quantum physics are predicted to have profound impacts on modern society. For example, quantum computers may hold the key to solving problems that are too complex for today’s most powerful supercomputers, and a quantum internet could ultimately protect the worlds information from malicious attacks...

Researchers have reproduced Michelangelo’s David as a miniature in metal. Their achievement highlights the potential of a special 3D printing method. There he is, standing upon his pedestal: David by Michelangelo. A world-famous statue that nearly every child can recognise. But this David is just 1 millimeter tall, pedestal included, and is made not of marble like the 5.17-meter original, but of pure copper.

It was created using 3D printing by Giorgio Ercolano from Exaddon, an offshoot of ETH spin-off Cytosurge, together with the team led by ETH Professor Tomaso Zambelli from the Laboratory of Biosensors and Bioelectronics...

Engineers calculate the ultimate potential of next-generation solar panels. Most of today’s solar panels capture sunlight and convert it to electricity only from the side facing the sky. If the dark underside of a solar panel could also convert sunlight reflected off the ground, even more electricity might be generated.

Double-sided solar cells are already enabling panels to sit vertically on land or rooftops and even ho...

Researchers create a polymer thermal regulator that can quickly transform from a conductor to an insulator, and back again. This control of heat flow at the nanoscale opens up new possibilities in developing switchable thermal devices, solid-state refrigeration, waste heat scavenging, thermal circuits, and computing. This is the first time that this work has been demonstrated experimentally.

Polymers are used to develop various materials, such as plastics, nylons, and rubbers...
