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 ...
Fitness needs the right timing
Molecular components of the endogenous clock in the green lineage
07-Apr-2022
Life on Earth runs in 24-hour cycles. From tiny bacteria to human beings, organisms adapt to alterations of day and night. External factors, such as changes in light and temperature, are needed to entrain the clock. Many metabolic processes are controlled by the endogenous clock. Scientists at ...
Catalytic hydrogen generation – without expensive precious metals
Researchers develop compact and cost-effective molecular photosystem for light-driven hydrogen generation
25-Mar-2022
A research team from Friedrich Schiller University Jena has developed a molecular photosystem inspired by nature that generates hydrogen under visible light irradiation. In contrast to other existing systems of this type, it functions without the use of precious or heavy metals. Low-cost and ...
Turbo boost for materials research
Researchers train AI to predict new compounds
10-Dec-2021
A new algorithm has been designed to help discover previously unknown material compounds. It was developed by a team from Martin Luther University Halle-Wittenberg (MLU), Friedrich Schiller University Jena and Lund University in Sweden. The researchers designed a form of artificial intelligence ...
Artificial intelligence helps to find new natural substances
New method enables fast and confident identification of previously unknown small molecules
18-Oct-2021
More than a third of all medicines available today are based on active substances from nature and a research team from the University of Jena has developed a procedure to identify small active substance molecules much more quickly and easily. Secondary natural substances that occur in numerous ...
Small molecules with a dual function
How a small RNA and a small protein regulate the metabolism of cholera bacteria and the production of the cholera toxin
13-Oct-2021
The human gut is a multi-species habitat that can control our health and well-being. Bacteria, viruses and microbial fungi are part of this complex microbial community and help us with our digestion and immune defense. If the intestinal flora is impaired, for example by contaminated drinking ...
Making the invisible visible
New method for studying atomic structures in material surfaces
21-May-2021
Researchers from Friedrich Schiller University Jena, the University of California Berkeley and the Institut Polytechnique de Paris use intense laser light in the extreme ultraviolet spectrum to generate a non-linear optical process on a laboratory scale – a process which until now has only been ...
Novel approach to the storage of solar energy
Molecular approach enables light-driven photochemistry in the dark for the first time
21-Sep-2020
Using the energy from the sun as efficiently as nature does and converting it into chemical energy could drastically reduce global CO2 emissions. A research team from the Leibniz Institute of Photonic Technology (Leibniz IPHT) and the Friedrich Schiller University Jena has now come one step ...
Water bacteria have a green thumb
Newly discovered species of bacteria produce bioactive natural substances
16-Jun-2020
The sheer endless expanses of the oceans are hostile deserts — at least from the perspective of a bacterium living in water. Tiny as it is, its chances of finding sufficient nutrients in the great mass of water would seem to be vanishingly small. However, as in other deserts, there are ...
Synapses in 3D
Scientists develop new method to map brain structures
12-Nov-2019
Our brain consists of countless nerve cells that transmit signals from one cell to the next. The connections between these cells, the synapses, provide a key to understanding how our memory works. An American research team in collaboration with Rainer Heintzmann from the Leibniz Institute of ...
