New metabolism discovered in bacteria

They make sauerkraut sour, turn milk into yogurt and cheese, and give rye bread its intensive flavour: bacteria that ferment nutrients instead of using oxygen to extract their energy. Acetobacterium woodii (short: A. woodii) ...

Light burns with new acids

Researchers at Nara Institute of Science and Technology (NAIST) report a photo-acid generator (PAG) that generates Lewis acids with a quantum yield that is vastly superior to PAGs that generate Brønsted acids. The new PAG ...

Microorganisms fed with toxic gas to produce biofuel

Today, various processes are used to convert organic waste into biogas. By combining two different processes, it is possible to obtain even more of valuable substances such as hydrogen and methane. The key is to make the ...

Antibiotics: New substances break bacterial resistance

Researchers at the Martin Luther University Halle-Wittenberg (MLU) have developed a promising new class of active ingredients against resistant bacteria. In initial tests in cell cultures and insects, the substances were ...

Rapid test to ensure high milk quality

Standards of food safety and food quality have never been higher in Germany and throughout the European Union. This is especially true in the dairy industry. Yet despite such high standards, traces of impurities, pesticides ...

Magnetic 'springs' break down marine microplastic pollution

Plastic waste that finds its way into oceans and rivers poses a global environmental threat with damaging health consequences for animals, humans, and ecosystems. Now, using tiny coil-shaped carbon-based magnets, researchers ...

Slime mold absorbs substances to memorize them

In 2016, CNRS scientists demonstrated that the slime mold Physarum polycephalum, a single-cell organism without a nervous system, could learn to no longer fear a harmless but aversive substance and could transmit this knowledge ...

Scientists find persistent organic pollutants in animal fur
