New agents to combat a dangerous pathogen

08/01/2022
Smallpox viruses - here seen under the microscope - are among the deadliest pathogens in human history. Not quite as dangerous, but still worrying, is the current outbreak of monkeypox.

Poxviruses pose a threat to humanity that should be taken seriously, as the current outbreak of monkeypox shows. A research team from the University of Würzburg is now working on the development of new drugs.

Life-like organ replicas - so-called 3D organoids - are a good way to research disease processes. A team from the University of Würzburg has now presented a kind of blueprint for such a model of the cervix.

Photos of the grasshopper species Gravel Grasshopper, Green Mountain Grasshopper, and the Wart-biter.

Little is known about the food webs of herbivorous insects. A team from the Würzburg Biocenter is investigating, in Lower Franconia as well as in the Berchtesgaden Alps.

Microscopy showing the fragmentation of mitochondria

Dormant herpesviruses induce their reactivation via a previously unknown cellular mechanism mediated by a viral microRNA. Würzburg researchers show this in the journal "Nature".

When male bees don’t get lucky

04/25/2022
Ein Forschungsteam hat untersucht, ob Fungizide beim Paarungsverhalten der Mauerbiene (Osmia cornuta) eine Rolle spielen könnten.

Do pesticides have anything to do with the decline in bee populations? A research team led by the University of Würzburg has investigated - and found a connection between fenbuconazole and the insects' mating behavior.

What Makes Plants Electrically Excitable

3-Dimensional sketch of the TPC1 channel protein looking at the vacuolar pore entrance from above.

In humans, only nerves and muscle cells are electrically excitable, whereas in plants almost all cells are. This is due to a sophisticated mechanism in an ion channel of the vacuole.

Plants Under Anaesthesia

02/18/2022
An anaesthetised Venus flytrap (above) can no longer close when stimulated (ant). Reason for this is that ether prevents the propagation of a calcium signal from the sensory hair into the trap (right).

The carnivorous Venus flytrap can be anaesthetised with ether. Some surprising parallels to anaesthesia in humans emerge.

Where Wild Honeybees Survive

02/16/2022
Bee colonies also use hollow electricity poles as nest sites (here a photo from Belgium).

In northern Spain, wild honeybees use hollow electricity poles as nesting cavities. Natural areas in the surroundings promote the colonies’ chances to survive the winter.
