Imaging

For the first time, ETH materials scientists are measuring the rolling friction of tiny, micrometre-sized particles. These measurements permit them to better understand everyday products such as concrete.

These small particles are reminiscent of paper flowers or desert roses. Physicians can use them to guide medicines to a precise destination within the body. Better yet, the particles can easily be tracked using ultrasound as they scatter sound waves.

A team of three European researchers will develop an imaging method to non-invasively measure the stiffness of moving organs such as the heart. The researchers will be supported by the European Research Council.

In dementia diseases such as Alzheimer's, incorrectly folded proteins accumulate in the brain. Empa researchers have now resolved a particularly active species of protein fibrils with unprecedented precision. The formation of potentially toxic molecules on the surface of protein fibrils was studied from early to late stages spanning over a period of hours. The researchers recently published their results in the journal Science Advances.

Researchers at ETH Zurich have analysed down to the smallest detail the unusual arsenal of weapons that a predatory marine bacterium has at its disposal. Perhaps one day these weapons could also be put to use in medicine.

Researchers at EPFL unlock a detailed understanding of brain and spinal cord interactions. The tool paves the way for future research breakthroughs and innovative therapeutic approaches.
