From prostheses to children's toys, car parts or sporting goods: The possible applications of 3D printing seem limitless and show how popular this technology has become. The range of plastics used in this process is constantly growing, and with it the potential to manufacture bio-based products from them. However, in order to print highly complex three-dimensional objects, so-called support structures are often required.

For many people, pasta is a natural part of their meals. For 250 million people worldwide, however, such food causes serious health problems. The reason: they suffer from celiac disease - an intolerance to gluten, a protein found in many types of grain. Although there are already gluten-free products on the market, the baked goods lack the right texture. This is because gluten is a gluten protein that provides stability to air bubbles in dough and bread and gives volume to pasta. Without the supporting gluten framework, the dough collapses.

With their high protein content, legumes are healthy and are now an integral part of many plant-based foods. The consumer trend toward healthy eating is causing demand for vegan foods to rise further. Seed specialist KWS Saat SE & Co. KGaA and the Berlin-based start-up company VF Nutrition GmbH, better known under the brand name vly, have now agreed a development partnership lasting several years.

Hydrothermal vents are among the few places where there is sufficient energy in the deep sea to support life. Forms of this energy are crude oil and natural gas, which are formed from deposited organic material by the high heat from the Earth's interior. A team of researchers from Bremen has now been able to demonstrate that microorganisms indigenous to hydrothermal vents use the alkanes contained in petroleum as a food source. Until now, it was only assumed that certain microbes are capable of degrading alkanes in an oxygen-free environment.

Climate change and industrialization put pressure on ecosystems worldwide - including the valuable resource soil. Especially its ability to store important greenhouse gases is being impaired. It has long been known that microorganisms play an important role in the conversion of organic carbon in the soil. However, how biological and environmental processes affect carbon storage in soils was largely unknown until now. An international team of researchers with the participation of the Max Planck Institute for Biogeochemistry in Jena now provides answers.

According to weather experts, the summer of 2022 was the hottest since weather records began. Temperatures above 30 degrees have long been normal in Germany, and even heat records of over 40 degrees Celsius are more frequent. Especially in densely built-up cities, heat and air pollution are increasingly becoming a problem for people. Studies have shown that green spaces, but also watering holes or greened house facades, can improve the urban climate.

Without roots, plants could not exist: Not only do they anchor the plant in the soil, they also supply it with water and nutrients. Influencing the shape and size of root growth would therefore enable plant breeding to produce more robust and higher-yielding crops. A first step on this path could be a study by an international team of researchers who have now further elucidated the molecular processes involved in root growth of the model plant Arabidopsis thaliana.
