Earth Comission (2023): Safe and just Earth system boundaries

In their study, published in the journal Nature, the group led by Johan Rockström of the Potsdam Institute for Climate Impact Research (PIK) writes that seven out of eight "safe and fair boundaries" of the Earth system have already been exceeded. In the researchers' view, humans are endangering the stability and resilience of the planet with their current way of life.

How the TOR protein regulates root growth

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.

Producing basic chemicals with wood and hot steam

Agriculture and forestry produce enormous quantities of residual materials such as hay, straw, wood or plant residues. The bioeconomy strives for the efficient and sustainable utilization of such raw materials in order to close cycles and thus conserve resources and the environment. Some of these valuable by-products of agricultural and forestry production are already being used to generate energy and materials for the production of new biobased products. However, neither the material nor the energy potential has been sufficiently exploited.

Algae biotechnology: creating profitable processes

Shifting away from fossil raw materials and toward biobased alternatives: This credo has become a matter of course in research and industry as a result of the climate crisis. From biofuels to bioplastics and biobased fine chemicals, the alternatives are proliferating - at least in theory. This is because the technically feasible processes are not always economically profitable in the end. Frequent reasons for this are insufficient product yields or overly complex purification steps.

Award for research on meat substitutes

Meat substitute products have long been established on the market. To encourage even more people to eat alternative meat products, the products must be able to compete with the animal original not only in terms of taste, but also texture and mouthfeel. At the TU Berlin, Anja Maria Wagemans studies the structure formation of such innovative foods. For her research, the food technologist and junior professor was awarded the Young Scientist Award, which comes with 10,000 euros in prize money. The award was presented in May by Berlin's Governing Mayor Kai Wegner.

Starch based foam film

Foamed plastics are frequently used for packaging. They are mostly made of polystyrene, polyethylene or polyurethane - and are thus ultimately based on petroleum. The production process is clearly not sustainable, and the situation is often no better at the product's end of life: After a single use, they are usually discarded - even if done correctly, foamed materials are rarely recycled today. Instead, they end up in thermal recycling.

Higher wheat yields with silicon fertilizers

In agriculture, large quantities of fertilizers are often used to increase yields per unit area. However, this practice has long been controversial because it damages soils, the environment and the climate alike. In addition, heat and drought are putting increasing pressure on soils and crops, leading to crop failures. How can we prevent soils from drying out while increasing yields to ensure food security in the future? A study led by the Leibniz Center for Agricultural Landscape Research (ZALF) provides promising results.
