Perseverant bacteria challenge antibacterial treatment

Bacterial perseverance is a new phenomenon that helps explain how bacteria adapt to survive antibiotic treatments. A group of researchers at Uppsala University have studied how individual bacteria react when exposed to different ...

Polarity proteins shape efficient 'breathing' pores in grasses

Grasses have "respiratory pores" (called stomata) that open and close to regulate the uptake of carbon dioxide for photosynthesis on the one hand and water loss through transpiration on the other. Unlike many other plants, ...

Shedding light on the origin of complex life forms

How did the complex organisms on Earth arise? This is one of the big open questions in biology. A collaboration between the working groups of Christa Schleper at the University of Vienna and Martin Pilhofer at ETH Zurich ...

The clever glue keeping the cell's moving parts connected

Researchers from Paul Scherrer Institute PSI and ETH Zurich have discovered how proteins in the cell can form tiny liquid droplets that act as a smart molecular glue. Clinging to the ends of filaments called microtubules, ...

Some cancer cells may not be as immortal as previously thought

Scientists at Johannes Gutenberg University Mainz (JGU) and the Institute of Molecular Biology (IMB) in Mainz may have discovered new insights into how cancer cells regulate the ends of their chromosomes, called telomeres. ...

How cells gain control over their bacterial symbionts

Modern eukaryotic cells contain numerous organelles, which once used to be independent bacteria. In order to understand how these bacteria were integrated into the cells in the course of evolution and how they are controlled, ...
