DNA folded in compliant helix
In an Advance Online Publication biophysicist John van Noort and others show using magnetic tweezers that DNA is folded in compliant helices of chromatin. This allows enzymes access to the DNA needed for gene expression. Van Noort's research group made the discovery in close partnership with researchers…

This is how a channel is formed between two organelles
The channel through which two cell components exchange material appears to form at the edge of their contact surface, and not in the middle. This was discovered by the Leiden physical chemists Jelger Risselada and Edgar Blokhuis together with researchers from the University of Lausanne in Switzerland.…

Graphene is a thoroughbred that has to be tamed
Electrons in graphene behave like light particles; they have no mass and can penetrate everything: very useful if you dream about nano-electronics. But you do have to channel them. Carlo Beenakker will be researching how. He has been awarded an ERC Advanced Grant of 1.5 million euro to carry out this…

‘Ultimately, the goal is to develop antibiotics for tuberculosis with a lower risk of resistance’
Tuberculosis stands as one of the most lethal infectious diseases worldwide. A significant challenge in combatting tuberculosis lies in the emergence of antibiotic resistance triggered by genetic alterations, commonly known as mutations. These mutations can diminish the responsiveness to antibiotics,…

Photosynthesis works with valves
Photosynthesis is the origin of life on earth, but it is a phenomenon that is still barely understood. Take, for example, the extremely efficient mechanism of electron transport. Leiden researchers demonstrate for the first time where one particular cause of this might be found.

Caught in living cells: how bacteria regulate their genes to defend themselves
For the first time, it was shown in living cells how the bacterium E. coli regulates genes that help it survive in a new environment. Biochemist Fatema Zahra Rashid managed to do this using a technique she fine-tuned. Her research into changes in 3-dimensional chromosome structure offers clues for ways…

Tunnel vision alarm in the search for more efficient hydrogen cells
A tenacious postdoc researcher persuaded Professor Marc Koper to research the oxygen reduction reaction. In Koper's eyes, there was little of interest there. But they promptly discovered a whole new way to improve fuel cells on hydrogen and oxygen. Their article appeared in Nature Catalysis on 07 Ju…

Stacked graphene layers act as a mirror for electron beams
Stacked layers of graphene can act like a mirror for beams of electrons. Physicists Daniël Geelen and colleagues discovered this using a new type of electron microscope. In an article in Physical Review Letters, they describe their results, which could lead to the development of optics for electron…

Star birth: a slow and mysterious drama
A star does not just appear in the sky overnight. Its creation takes tens of thousands of years. Twenty years ago, astronomers took a picture of a star in its birth phase. The James Webb Space Telescope (JWST) could now capture that same star in much greater detail. This does not only provide beautiful…
