Microbes under power
In microbial electrosynthesis, microorganisms use CO2 and electricity to produce alcohol, for example. How this process works biologically, however, was previously only speculated. Researchers in Jena have now been able to confirm experimentally for the first time that bacteria use electrons from hydrogen and can produce more chemicals than previously known.

New method to synthesise cannabis plant compound
Cis-tetrahydrocannabinoids can now be produced synthetically, enabling pharmaceutical applications A group of researchers at Leipzig University has developed a new method for synthesising cis-tetrahydrocannabinol (THC) - a natural substance found in the cannabis plant that produces the characteristic psychoactive effect and has many potential applications, including in the pharmaceutical industry.

African Smoke Over the Amazon
At certain times in the year, more soot particles reach the Amazon rainforest from bush fires in Africa than from regional fires. Up to two-thirds of the soot above the central Amazon rainforest originates in Africa. These are the results of a study that has now been published in Nature Communications Earth and Environment.

New glass from the computer
Glass is a very special material: it can be produced in almost unlimited variety from compounds of almost all elements of the periodic table. The only prerequisite is that the components can be melted together and that the melt is then cooled quickly enough. In the process, the liquid mixture solidifies and forms a glass.

With formic acid towards CO2 neutrality
New synthetic metabolic pathways for fixation of carbon dioxide could not only help to reduce the carbon dioxide content of the atmosphere, but also replace conventional chemical manufacturing processes for pharmaceuticals and active ingredients with carbon-neutral, biological processes. A new study demonstrates a process that can turn carbon dioxide into a valuable material for the biochemical industry via formic acid.

Where the borders between disciplines become blurred
Chemistry and physics, traditionally separate disciplines, are intermeshed in nano-technology The area where physics and chemistry meet lies somewhere in the realm of the minute - in the nano range: where molecules react with one another and the laws of quantum mechanics hold sway. This is the area which physicist Dr. Harry Mönig visualises at the Center for Nanotechnology (CeNTech) - with an atomic force microscope and a dedicated technology perfected by himself and a Münster team.

Scientists ’revive’ Stone Age molecules
Breakthroughs in ancient genome reconstruction and biotechnology are now revealing the rich molecular secrets of Paleolithic microorganisms. In a new study published in "Science", a transdisciplinary team of researchers led by the Leibniz Institute for Natural Product Research and Infection Biology, the Max Planck Institute for Evolutionary Anthropology, Friedrich Schiller University Jena and Harvard University reconstructed bacterial genomes of previously unknown bacteria dating to the Pleistocene.

How Spheres Become Worms
A previously unknown form of hydrogel formation has been elucidated: chemists found unusual interactions between polymers. Hydrogels? Many people use these substances without knowing it. As superabsorbents in nappies, for example, hydrogels absorb a lot of liquid. In the process, the initially dry material becomes Jelly-like, but it does not wet.

Green steel produced with ammonia
Ammonia synthesized in sun-rich countries could facilitate sustainable ironand steelmaking When it comes to sustainability and green steel, everybody talks about hydrogen. But current means of storing and transporting hydrogen request high pressures and low temperatures, which are both energetically and economically costly.

How one photon becomes four charge carriers
Some materials convert photons into more free charges than would be expected. Using an ultrafast film, researchers have now been able to get a picture of this process. Physicists from the University of Würzburg were also involved. Photovoltaics, the conversion of light to electricity, is a key technology for sustainable energy.

A mini-heart in a Petri dish
Reading time 4 min. Progress with organoids A team at the Technical University of Munich (TUM) has induced stem cells to emulate the development of the human heart. The result is a sort of "mini-heart" known as an organoid. It will permit the study of the earliest development phase of our heart and facilitate research on diseases.

Cells refine palm fat into olive oil
Study by the University of Bonn provides the first precise insight into important remodeling processes in adipose tissue For more than 50 years, it has been suspected that fat cells constantly remodel the lipids they store. Researchers at the University of Bonn have now demonstrated this process directly for the first time using culture cells.

First brew beer, then store electricity
Modern energy storage systems are an important building block for a climate-friendly future. "Modern" means not only that their performance meets the demands of a high-tech society, but also that they can be produced and recycled sustainably. In the search for new resources, scientists sometimes hit upon surprising raw materials - for example brewery waste.

Surprise in the Quantum World
Researchers from the Cluster of Excellence ct.qmat have achieved a significant milestone in the pursuit of energy-efficient quantum technologies by designing a ferromagnetic topological insulator. In 2019, an international research team headed by materials chemist Anna Isaeva, at that time a junior professor at ct.qmat (Complexity and Topology in Quantum Matter), caused a stir by fabricating the world's first antiferromagnetic topological insulator - manganese bismuth telluride (MnBi 2 Te4).

Emergence of solvated dielectrons observed for the first time
Team in conjunction with the University of Freiburg generates low-energy electrons using ultraviolet light Solvated dielectrons are the subject of many hypotheses among scientists, but have never been directly observed. They are described as a pair of electrons that is dissolved in liquids such as water or liquid ammonia.

Quantum effects demonstrated in the collision of hydrogen molecules with noble gas atoms
A research team of Freie Universität Berlin has shown how hydrogen molecules behave quantum mechanically when they collide with noble gas atoms such as helium or neon. In the study published in the journal "Science," the scientists used simulations to establish a direct link between measurements of atoms and molecules taken in experiments and theoretical models; the study includes both theoretical calculations and data from experiments conducted at the Technical University of Dortmund and the Weizmann Institute of Science (Israel).
