PSI imaging helps with rocket launches

Rockets from the European Space Agency (ESA) fly into space with support from the Paul Scherrer Institute (PSI). Imaging carried out at PSI in cooperation with Dassault Aviation ensures the quality of certain components of the Ariane 5 and Vega launch vehicles. With the help of the neutrons generated at the neutron source SINQ, PSI researchers are screening so-called pyrotechnic components that are installed in the ESA rockets. These components, which act like fuse cords and igniters, ensure, among other things, that the booster rockets are dropped at the right hundredth of a second. The Ariane launch on 20 June took place with components that had been examined at PSI.

Algorithm quickly finds hidden objects in dense point clouds

A new MIT-developed technique enables robots to quickly identify objects hidden in a three-dimensional cloud of data, reminiscent of how some people can make sense of a densely patterned "Magic Eye" image if they observe it in just the right way.

Perovskite solar cells tested for real-world performance—in the lab

It was only ten years ago that metal-halide perovskites were discovered to be photovoltaic materials. Today, perovskite solar cells are almost as efficient as the best conventional silicon ones, and there is much hope that they will become a highly efficient and low-cost alternative, as they can be manufactured by rather simple and fast methods like printing.

A new drug target for chemically induced Parkinson's disease

More than three decades ago, scientists discovered that a chemical found in a synthetic opioid, MPTP, induced the onset of a form of Parkinson's disease. In a new study led by scientists from the School of Veterinary Medicine, researchers found that an enzyme in the body can metabolize compounds formed in the brain from alkaloids present in certain foods and tobacco into MPTP-like chemicals, triggering a neurodegenerative condition in mice.
