From 22 to 24 October, researchers of the MARBLES-project informed museum visitors about microbes: bacteria and fungi that live all around us. The event was organised around the Micro-day of Leiden, which is this year’s EU City of Science.

With the necessary measures, researchers restart their work in various laboratories. The Leiden Cell Observatory is one of the places where scientists resume their lab work.

Physicists, including Leiden researcher, Sanli Faes, have devised a new technique for studying processes at microscale rapidly and extremely precisely. This new method will make it easier to develop antiviral medication. And it doesn’t stop there. Publication in ACS Nano.

The guardian of our genome, the protein MutS, scans the DNA for spelling errors and makes sure they are corrected. An essential process for our health. Researchers at Leiden University Medical Centre (LUMC) have discovered precisely how this protein works by making MutS visible with cryo-electron microscopy.…
