How the first biomolecules could have been formed

International team shows that the first biologically relevant compounds could have originated on Earth's surface

14-Jun-2022 - The chemical precursors of present-day biomolecules could have formed not only in the deep sea at hydrothermal vents, but also in warm ponds on the Earth's surface. The chemical reactions that may have occurred in this “primordial soup” have now been reproduced in experiments by an international ...

Could the blueprint for life have been generated in asteroids?

“I was amazed that they had seen cytosine, which is very fragile”

29-Apr-2022 - Using new analyses, scientists have just found the last two of the five informational units of DNA and RNA that had yet to be discovered in samples from meteorites. While it is unlikely that DNA could be formed in a meteorite, this discovery demonstrates that these genetic parts are available for ...

Watching the charge move in photoexcited molecules

Research opens up the possibility to map the charge flowing inside the molecular landscape

14-Jan-2022 - An international research team led by Markus Gühr’s group at the University of Potsdam performed laser experiments at Deutsches Elektronen-Synchrotron DESY to monitor charge motions in light-excited molecules of thiouracil, which is a modified nucleobase. This class of molecules has a variety of ...

Searching for the chemistry of life

Study shows possible new way to create DNA base pairs

06-Oct-2020 - In the search for the chemical origins of life, researchers have found a possible alternative path for the emergence of the characteristic DNA pattern: According to the experiments, the characteristic DNA base pairs can form by dry heating, without water or other solvents. The team led by Ivan ...

Chirality in 'real-time'

Circular dichroism in the deep ultraviolet

11-Jan-2019 - In nature, certain molecules with the same chemical composition, can exist in two different shapes that are mirrors images of each other, much like our hands. This property is known as "chirality" and molecules with different chirality are called enantiomers. Enantiomers can exhibit entirely ...
