Published Deciphering the molecular dynamics of complex proteins
(via sciencedaily.com) Which structures do complex proteins adopt in solution? Biophysicists answer this question using the example of ubiquitin dimers as well as a new combination of high-resolution NMR spectroscopy and sophisticated computer simulations.
Published Sharing chemical knowledge between human and machine
(via sciencedaily.com) Researchers have developed a platform that uses artificial neural networks to translate chemical structural formulae into machine-readable form. With this platform, they have created a tool with which this information from scientific publications can be automatically fed into databases. Until now, this had to be done literally by hand and was time-consuming.
Published Quantum physicists simulate super diffusion on a quantum computer
(via sciencedaily.com) Quantum physicists have successfully simulated super diffusion in a system of interacting quantum particles on a quantum computer.

Published Magnonic computing: Faster spin waves could make novel computing systems possible
(via sciencedaily.com) Research is underway around the world to find alternatives to our current electronic computing technology, as great, electron-based systems have limitations. A new way of transmitting information is emerging from the field of magnonics: instead of electron exchange, the waves generated in magnetic media could be used for transmission, but magnonics-based computing has been (too) slow to date. Scientists have now discovered a significant new method: When the intensity is increased, the spin waves become shorter and faster -- another step towards magnon computing.
