The robot that grips without touching

ETH Pioneer Fellow Marcel Schuck is developing a robotic gripper that can manipulate small and fragile objects without touching them. The technology is based on sound waves.

Principles for a green chemistry future

In the most recent issue of the academic journal Science, the case is made for a future where the materials and chemicals that make up the basis of our society and our economy are healthful rather than toxic, renewable rather ...

A new twist on quantum communication in fiber

New research done at the University of the Witwatersrand in Johannesburg, South Africa, and Huazhang University of Science and Technology in Wuhan, China, has exciting implications for secure data transfer across optical ...

'Jumping genes' help stabilize DNA folding patterns

"Jumping genes"—bits of DNA that can move from one spot in the genome to another—are well-known for increasing genetic diversity over the long course of evolution. Now, new research at Washington University School of ...

Dance of the honey bee reveals fondness for strawberries

Bees are pollinators of many wild and crop plants, but in many places their diversity and density is declining. A research team from the Universities of Göttingen, Sussex and Würzburg has now investigated the foraging behaviour ...

Increasing opportunities for sustainable behavior
