Where exactly is each atom located within a material? PSI researchers have trained an AI system to find the missing positions of hydrogen atoms very quickly. This should aid in hydrogen storage research and could also be applied in the field of battery research.
On the trail of the missing hydrogen atoms
Representations of the crystal structures of materials often lack information about the positions of hydrogen atoms. PSI researchers have found a way to fill this gap, using AI.

Over the years, the 3D packaging of our DNA in the cell nucleus – known as chromatin – changes. As PSI researchers have now shown, this is why older cells are no longer as flexible.
Why cells respond “incorrectly” in old age
Researchers at PSI have established why the cells in our body react differently to stimuli and signals in old age compared with young cells. Their studies on human skin cells have shown that the chrom...
