Resting Chlamydia (left; bright circles), which are held without glutamine. After the addition of glutamine (right) the bacteria enter the division stages (darker circles).

If chlamydiae want to multiply in a human cell, the first thing they need is a lot of glutamine. Würzburg researchers have clarified how the pathogenic bacteria obtain this substance.

Left two sperm-forming cells expanded with ExM-SIM and imaged with a diffraction limited microscope. On the right, a detailed 3D image of a single synaptonemal complex. The 3D information is colour-coded, the measuring bar on the left corresponds to 25 micrometres, the bar on the right to three micrometres.

New details are known about an important cell structure: For the first time, two Würzburg research groups have been able to map the synaptonemal complex three-dimensionally with a resolution of 20 to 30 nanometres.

An island of the Azores: It is an example of an underwater volcano that has reached the sea surface. The crater is clearly visible.

Explosive volcanic eruptions are possible deep down in the sea – although the water masses exert enormous pressure there. An international team reports in the journal "Nature Geoscience" how this can happen.

Premature leaf senescence of a beech tree during the 2018 event, followed by lacking leaf flushing and canopy dieback in the following year.

No year has been as hot and dry as 2018 since climate records began. Central European forests showed severe signs of drought stress. Mortality of trees triggered in 2018 will continue for several years.

Schematic representation of the formation and presentation of cryptic peptides.

Using a newly developed method, Würzburg researchers were able to identify thousands of cryptic peptides on the surface of cells for the first time. These findings could provide a new starting point for cancer immunotherapy.

The department of chemistry and the physics department at JMU scored particularly well in the Nature Index ranking.

The Nature Index 2020 is an indicator of the University of Würzburg's strong research performance in natural sciences and life sciences, ranking 104th in the world and 5th in Germany in the recently published ranking.

When matter falls towards the black hole at the center of a galaxy, part of it is accelerated outwards at nearly the speed of light. NASA's Fermi Gamma-ray Space Telescope can be used to observe such so-called jets.

Some galaxies may have two black holes at their centers. This is shown by the analysis of the gamma rays emitted by them. Würzburg astrophysicist Sara Buson was involved in the study.

Effective drugs to treat Covid-19 are in short supply. Scientists at JMU have now identified another compound that, at least in the laboratory, effectively combats corona viruses.

A standard drug for the treatment of depression might also be effective against Covid-19, a new study by Würzburg scientists shows which has been published on a preprint server.
