Surrounded by low achievers—High on positive emotions?

The phenomenon tremendously important for a person's self-perception is referred to as the "Big Fish, Little Pond Effect" (BFLPE). A fish perceives itself as big when it swims in a comparatively small pond. This means: If ...

Novel enzyme discovered in intestinal bacteria

The human intestinal system contains a complex community of microorganisms, the intestinal microbiome, which metabolizes food components that have not readily been digested. However, there are also microbial degradation processes ...

Team develops first genetic switch for C. elegans

With their first ever RNA-based inducible system for switching on genes in the roundworm Caenorhabditis elegans (C. elegans), two researchers from the University of Konstanz have closed a significant gap in genetic switches. ...

From a plant sugar to toxic hydrogen sulfide

In a doctoral research project conducted at the Department of Biology, researchers have described the degradation of the dietary sugar sulfoquinovose by anaerobic bacteria to toxic hydrogen sulfide for the first time—increased ...

Obtaining polyester from plant oil

The development of future technologies that are not based on mineral oil and can be used for producing chemicals and plastics is one of the major tasks in modern materials science and a key challenge that needs to be addressed ...

Supercomputers without waste heat

Generally speaking, magnetism and the lossless flow of electrical current ("superconductivity") are competing phenomena that cannot coexist in the same sample. However, for building supercomputers, synergetically combining ...

30 years of experimental evolution results in a new sex chromosome

On 3 December 2018, the laboratory of Professor Axel Meyer, University of Konstanz published new findings of an experimental evolutionary project that ran for 30 years on the genomic mechanisms of sex determination in swordtail ...

Study finds indications for recovery after ecosystem pollution

Environmental damage caused by human activity can reduce the number of plant and animal species dramatically. At the same time, very little is known about how biodiversity recovers after ecosystem pollution is curtailed and ...

Sweet lysine degradation

Researchers from the Departments of Chemistry and Biology at the University of Konstanz have gained fundamental new insights into the degradation of the amino acid lysine—carcinogenic oncometabolites as intermediate products
