Even fish society shows social control and nepotism
Even fish society shows social control and nepotism
Cichlids living in groups tend to turn a blind eye to their relatives shirking their duty to help as desired in various tasks in the group, such as caring for the brood. Animals that are not related to them don't seem to be offered the same lenient treatment. Researchers at the University of Bern have now been able to prove the existence of this form of "nepotism" in fish for the first time in experiments.

New findings on skin disinfection before operations
New findings on skin disinfection before operations
Surgery carries the risk of infection at the surgical site. Proper skin disinfection before the incision minimizes this risk. Two disinfectants are used worldwide for this purpose, one of which was previously considered to be better. A joint study by Inselspital, Bern University Hospital and the University of Bern in collaboration with the University Hospitals of Basel and Zurich now shows that both agents are equally effective.

Curiosity promotes biodiversity
Curiosity promotes biodiversity
Cichlid fishes exhibit differing degrees of curiosity. The cause for this lies in their genes, as reported by researchers from the Universities of Bern and Basel in the journal Science. This trait influences the cichlids' ability to adapt to new habitats. Exploratory behavior is one of the fundamental personality traits of animals - and these traits influence their probability of survival, among other things.

Climate change in the early Middle Ages triggered by volcanic eruptions in Iceland
Climate change in the early Middle Ages triggered by volcanic eruptions in Iceland
Icebergs on the Bosporus and a frozen Black Sea: an international study by the University of Bern with the participation of the Austrian Academy of Sciences shows how volcanic eruptions on Iceland influenced the European climate in the early Middle Ages and led to severe winter cooling anomalies. It was one of the coldest winters the region has ever experienced: In 763, large parts of the Black Sea froze over and icebergs were sighted on the Boporus.

Our deep sleep reveals how cooperative we are
Our deep sleep reveals how cooperative we are
Each person has their own sleep profile, which can be identified by the electrical brain activity during sleep. Now, researchers from the University of Bern show that brain waves during periods of deep sleep in a specific area of the brain can be used to determine how cooperative and prosocial a person is in their everyday life.

How fungal infections cause blood poisoning
How fungal infections cause blood poisoning
Blood poisoning caused by a fungal infection is a severe, life-threatening condition. Researchers at the University of Bern have now discovered a mechanism that helps a yeast fungus to spread more easily within the body. The immune system, of all things, plays a major role in this process. These findings could open up new therapeutic avenues for blood poisoning caused by yeast, but also for other invasive fungal infections.

Could artificially dimming the sun prevent ice melt?
Could artificially dimming the sun prevent ice melt?
With methods of so-called geoengineering, the climate could theoretically be artificially influenced and cooled. Bernese researchers have now investigated whether it would be possible to prevent the melting of the West Antarctic ice sheet by artificially "dimming the sun". The results show that artificial influence does not work without decarbonization and entails high risks.
