Using an ultra fast-scanning atomic force microscope, a team of researchers from the University of Basel has filmed “living” nuclear pore complexes at work for the first time. Nuclear pores are molecular machines that control the traffic entering or exiting the cell nucleus. In their article published in “Nature Nanotechnology”, the researchers explain how the passage of unwanted molecules is prevented by rapidly moving molecular “tentacles” inside the pore.
Scientists from the University of Basel have developed a new method that has enabled them to image magnetic fields on the nanometer scale at temperatures close to absolute zero for the first time. They used spins in special diamonds as quantum sensors in a new kind of microscope to generate images of magnetic fields in superconductors with unrivalled precision.
When medication is used to shut off the oxygen supply to tumor cells, the cells adapt their metabolism in the medium term – by switching over to producing energy without oxygen. This observation by biomedical scientists at the University of Basel and University Hospital Basel could be used for treatment.
The microscopic world is governed by the rules of quantum mechanics, where the properties of a particle can be completely undetermined and yet strongly correlated with those of other particles. Physicists from the University of Basel have observed these so-called Bell correlations for the first time between hundreds of atoms.
Forest trees use carbon not only for themselves; they also trade large quantities of it with their neighbours. The extensive carbon trade among trees – even among different species – is conducted via symbiotic fungi in the soil.
The globally increasing light pollution has negative effects on organisms and entire ecosystems. The consequences are especially hard on nocturnal insects, since their attraction to artificial light sources generally ends fatal. A new study by Swiss zoologists from the Universities of Basel and Zurich now shows that urban moths have learned to avoid light.
Researchers of the University of Basel and Empa have gotten a step closer to engineering artificial muscles: they have developed a method to generate nanometer-thin silicone films.
Natural products from bacteria and fungi are an important source of current and novel drugs, such as antibiotics. They are produced in the microorganisms by giant protein complexes that resemble industrial assembly lines. In the future, engineered assembly line proteins may help to produce a variety of drug candidates.
Spiders are known to be the classic example of insectivorous predators. Zoologists from the University of Basel, the US and UK have now been able to show that their diet is more diverse than expected. Their findings show that spiders like to spice up their menu with the occasional vegetarian meal.
