How Salmonella grow together in the gut and exchange antibiotic resistance
How Salmonella grow together in the gut and exchange antibiotic resistance
The ability to utilize a mere single alternative food source is all it takes for diarrhoea causing Salmonella bacteria to bloom when a gut is already colonized by a closely related strain, according to researchers from ETH Zurich. This coexistence enables the exchange of antibiotic resistance. Bacteria are growing more resistance to common antibiotics, and one key factor contributing to this problem is the exchange of antibiotic resistance genes between closely related bacterial strains.

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.

Study undermines evolutionary rule
Study undermines evolutionary rule
According to Cope's rule, today's animal species are on average larger than older species of the same genus. A large-scale study led by a researcher at the University of Fribourg has just demonstrated that this is not the case in turtles . Paleontologists have noticed that, in the course of their evolution, certain species tend to get bigger and bigger.

Substances from corn roots influence wheat yields
Substances from corn roots influence wheat yields
Corn roots secrete certain substances that affect the quality of the soil. In certain fields, this effect increases the yield of wheat planted after corn in the same soil by more than 4%. This has been demonstrated by researchers at the University of Bern. Although the findings from several field experiments show that such effects are highly variable, they could nevertheless contribute in the long term to making the cultivation of cereals more sustainable without additional fertilizers or pesticides.

Favoured asylum seekers are young, female and fleeing war
An international research group with ETH professor Dominik Hangartner has found that solidarity with refugees in Europe has remained stable, despite repeated refugee crises. While there is a tendency to view refugees from Ukraine more positively, this does not come at the expense of other groups. Russia's attack on Ukraine has resulted in one of the largest movements of refugees since the Second World War.
