How is it possible for a picture of Albert Einstein to turn into Marylin Monroe? Physics students and lecturers at the University of Bonn now have a new experiment at their disposal that illustrates "Fourier optics", a method particularly useful for the targeted processing of images. The experiment came about through an initiative by physicist and alumnus Dr. Michael Kösters. Last year, he and two colleagues received the German Future Prize, which is awarded by the President of Germany for outstanding research and development projects in the field of technology and innovation. In a lecture at the Physics Colloquium of the University of Bonn, Michael Kösters spoke about his field of research, namely laser systems for the generation of extreme ultraviolet light for Mikrochip manufacturing, and presented the demo experiment. It will be used in lectures and practical courses.
How can parcel delivery be optimized with a mass of routes and parcels? More precisely, how can algorithms learn and use the knowledge and behavior of experienced drivers? To solve this problem, mathematician Prof. Dr. Stephan Held from the University of Bonn, together with two colleagues from Canada and Denmark, has now emerged as the winner of a worldwide competition - the "Amazon Last Mile Routing Research Challenge". The competition is organized by Amazon and the MIT Center for Transportation & Logistics in Boston. The prize money of $100,000 for the winning team attracted 2,285 participants from all over the world this year.
What influence do endogenous cannabinoids have on neurodegenerative diseases? Bolanle Fatimat Olabiyi is investigating this question in her doctoral thesis at the ImmunoSensation2 Cluster of Excellence. Her big goal for the future is to continue boosting research in her home country of Nigeria. An article from forsch 2021/01
Which effects did the heat wave of summer 2020 have in Siberia? In a study led by the University of Bonn, geologists compared the spatial and temporal distribution of methane concentrations in the air of northern Siberia with geological maps. The result: the methane concentrations in the air after last year's heat wave indicate that increased gas emissions came from limestone formations beneath the thawing permafrost. The study is published in the journal Proceedings of the National Academy of Sciences (PNAS).
When we fixate an object, its image does not appear at the place where photoreceptors are packed most densely. Instead, its position is shifted slightly nasally and upwards from the cellular peak. This is shown in a recent study conducted at the University of Bonn, published in the journal Current Biology. The researchers observed such offsets in both eyes of 20 healthy subjects, and speculate that the underlying fixation behavior improves overall vision.
Teeth are the toughest and most durable parts of a mammal’s body and are often the only bits of fossils left after millions of years. We join Prof. Dr. Thomas Martin to explore the secret of teeth.
