Leaving some weeds between crops can help to combat pests on agricultural land, according to a new study carried out by the University of Bonn. This step has particularly positive effects in combination with other measures: the cultivation of different types of crops and planting strips of wildflowers. The results have now been published in the Journal of Pest Science.

Researchers at the University of Bonn have developed software that can simulate the growth of field crops. To do this, they fed thousands of photos from field experiments into a learning algorithm. This enabled the algorithm to learn how to visualize the future development of cultivated plants based on a single initial image. Using the images created during this process, parameters such as leaf area or yield can be estimated accurately. The results have been published in the journal Plant Methods.

Thousands of particles of light can merge into a type of “super photon” under suitable conditions. Physicists call such a state a photon Bose-Einstein condensate. Researchers at the University of Bonn have now shown that this exotic quantum state obeys a fundamental theorem of physics. This finding now allows one to measure properties of photon Bose-Einstein condensates which are usually difficult to access. The study has been published in the journal “Nature Communications.”

Dr. Julian Schmitt from the Institute of Applied Physics at the University of Bonn has been presented with the Industrie-Club Düsseldorf’s Science Award for 2024 in recognition of his outstanding work studying quantum gases of photons. The accolade is worth €20,000.
