Growth before photosynthesis: how trees regulate their water balance
Growth before photosynthesis: how trees regulate their water balance
In order for trees to grow, they need to control their water balance meticulously. A study by the University of Basel shows how trees react to drought - and revises previous perceptions. Plants have small pores on the underside of their leaves, known as stomata. When the sun rises, these pores open and the plants absorb carbon dioxide (CO2) from the atmosphere, which they need, in addition to sunlight and water, for photosynthesis.

Understanding which proteins work together
Understanding which proteins work together
Teamwork is crucial for proteins. Little is known, however, about which protein teams are actually active in which tissues. A new large-scale study by systems biologists at ETH Zurich is now redrawing the map. The human body and its organs are composed of a wide variety of cell types. Although all cells contain the same genes, they function very differently - partly because protein interactions differ between cells.

A step towards understanding machine intelligence the human way
A step towards understanding machine intelligence the human way
Researchers have discovered key 'units' in large AI models that seem to be important for language, mirroring the brain's language system. When these specific units were turned off, the models got much worse at language tasks. Large Language Models (LLMs) are not just good at understanding and using language, they can also reason or think logically, solve problems and some can even predict the thoughts, beliefs or emotions of people they interact with.
