Tingxiang Zou to lead a new Emmy Noether group

Tingxiang Zou's newly formed Emmy Noether group will study higher-dimensional versions of the Elekes-Szabó problem, a combinatorial problem with connections to geometry, algebra, and model theory. The research aims to explain cases where algebraic equations have an unexpectedly large solution set in finite grids.

Mitochondria influence lipid storage in cells

A recent study at the Universities of Bonn and Freiburg has discovered a previously unknown mechanism by which mitochondria influence lipid storage in cells. The molecular machine MIM complex and enzyme Ayr1 play key roles in this process, which affects cellular lipid metabolism.

Expensive food makes children fat

A study found that economic crises can have lasting negative impacts on children's physical development, including stunted growth and increased risk of obesity. The research used the Asian financial crisis in the 1990s as a case study, demonstrating how food price shocks can affect children's body measurements until they are young adults.

How a fungus leads to tissue growths in maize

A University of Bonn study has shown how the fungus Ustilago maydis takes over the plant's lateral root formation function, leading to massive tissue growths that divert energy and resources from defense. The findings provide valuable insights for breeding more resistant varieties of maize.

Chemical language models don't need to understand chemistry

Researchers at the University of Bonn found that chemical language models use statistical correlations to make predictions, rather than learning biochemical principles. The models can suggest plausible inhibitors for enzymes but fail to distinguish between functionally important and unimportant sequence parts.

Are they star clusters or extreme dwarf galaxies?

A team of astrophysicists from the University of Bonn and Iran has reclassified Ursa Major III as a compact star cluster containing a black hole core. Simulations suggest that the object's high mass-to-light ratio can be explained by the presence of dark stars rather than dark matter.
