Ants are usually found in large numbers. But how many of them are there in total on earth?

Have you ever asked yourself this question? A team led by Würzburg biologists Dr. Patrick Schultheiss and Dr. Sabine Nooten now has the answer. In addition to the number, the distribution was also determined.

Regardless of whether a face shows anger or joy: both generate attention. From the perspective of psychology, both are so-called approach-oriented emotion expressions.

Does eye-contact always attract attention? Not in every case, as a research team at the University of Würzburg’s Institute of Psychology has recently shown. Why not? Because context matters.

A Matabele ant treats the wound of a conspecific with an antimicrobial substance.

Biologist Dr. Erik Frank is researching how an African ant species treats its wounded. To continue his work, the German Research Foundation (DFG) has now granted him an Emmy Noether group.

A Venus flytrap with its prey (center): When the fly comes close to the sensory hairs, an action potential (AP) is triggered in the Venus flytrap (left). Compared to the animal AP of the fly (right), distinctly different ion fluxes are involved in the different APs. (Image: Sönke Scherzer/Uni Würzburg)

The Venus flytrap relies on glutamate receptors to catch prey by transmitting corresponding stimuli electrically. A research team at the University of Würzburg has now explained the underlying molecular mechanism.

Cross-section through a lymph node. The unconventional T cells (green), which have migrated from the tissue via the lymphatic channels, are located in the marginal sinus and in the interfollicular zone. Follicular B cells are shown in magenta, the lymph node capsule and lymphatic vessels in blue.

Lymph nodes trigger very different immune responses – depending on which body tissue they are connected to. Special T cells are responsible for this newly discovered relation.

Main building of the University of Würzburg.

The prestigious Shanghai Ranking counts the University of Würzburg among the top 250 universities in the world. In Germany, the University is on 11th place.

The cells in the top row were treated with the fluoxetine-like molecule AKS466 and then infected with SARS-CoV-2. The cells at the bottom were only infected; more viral RNA is detectable in them (lighter dots).

Completely unexpectedly, the enzyme ceramidase emerges as a new target structure for the therapy of SARS-CoV-2 infections. This is reported by Würzburg researchers in "Cells".

blueberries arranged on a table with daisies

Extracts from blueberries and blackcurrants prevent infection by measles and herpes viruses in cell cultures. Würzburg researchers were very surprised by this.

Schematic of a quantum sensor in which a biomolecule (pink) is anchored to a surface of hexagonal boron nitride on which the spin defect (red) is located. The latter operates as a sensitive probe for the environment.

The Free State of Bavaria is funding a new research project on quantum sensors with three million euros. Among other things, it aims to further improve molecular and medical imaging.
