Jonagold, Boskop or Elstar: apples are the Germans' favorite fruit. There are almost 2,000 different varieties in the country. The fruit has few calories, but many healthy ingredients such as vitamins and minerals. Researchers at Osnabrück University of Applied Sciences have developed an apple that is even richer in one health-promoting ingredient and is also said to strengthen the immune system. The innovation: The new fruit called Selstar impresses with a particularly high selenium content.

Competition is part of the natural environment: animals compete for food sources while plants mainly compete for light, which is essential to their growth. Similar to animals, plants have several options of how to react in the face of competition. Biologists from the University of Tübingen have now demonstrated that plants can in fact choose between alternative competitive responses according to the stature and densities of their opponents.

It’s been more than two years since international and national players across policy and science discussed the meaning of bioeconomy at the „Global Bioeconomy Summit“ (GBS). More than 700 guests from 82 countries came to Berlin for the two-day meeting in order to talk about such pivotal topics as global warming, protecting the environment, decarbonisation, and the fight against world hunger.

Almost all materials and surfaces are coated with a coat of paint or varnish today. It improves appearances and protects the material from corrosion. However, very few are bio-based. And in the past, paints and varnishes with bio-based binders or film formers have either been too expensive or could not meet the requirements. But through the use of modified starch, scientists at the Fraunhofer IAP in Potsdam-Golm and the Fraunhofer IPA in Stuttgart have found a sustainable and cost-effective solution.

Sharp teeth and spiky stings are a common defense mechanism across the animal kingdom. However, plants are using thorns and spikes as well, to ward off herbivores and insects. And now botanists of Bonn University found out that the use of calcium phosphate incrustations to strengthen their defences is far more widespread among plants than previously thought.

Beech, or rather beech wood is on the rise in Germany and is even used to manufacture bioplastics. However, similar to other tree species, beech also has to cope with the changing climate, meaning increasing temperatures and prolonged periods of drought. The researchers hope that the complete analysis of the beech genome could enable the targeted breeding of more climate-stress tolerant beech trees.

While the packaging industry has been moving towards using more renewable materials for quite some time now, the electronic industry has yet to adopt that strategy. The outer layers of coffee machines, computers and other devices are still mostly made of petrol-based plastics.

The global population is growing while resources are decreasing. Thus, the hitherto predominant diet of the industrialized nations, where people cover up to 70% of their protein needs from animal sources, will therefore no longer be sustainable in the near future. Although proteins are a necessary part of our diet, they can be obtained from a variety of sources. In addition to conventional meat and fish products as well as protein-rich vegetables such as soybean, there is another excellent protein source: insects.

Huge amounts of packaging waste accrue every day and much of it ends up polluting our oceans. However, not only the large pieces of plastic are dangerous to the environment but also the much smaller pieces of microplastic. And yet, they are still widely used in cosmetic care products such as scrubs and wash peelings. Researchers at the Fraunhofer Institute for Microstructure of Materials and Systems IMWS now developed a bio-based and – perhaps even more importantly – biodegradable alternative. 

Specialty chemicals company Clariant and biotechnology company Global Bioenergies have announced the development of a new bio-based polymer of renewable isobutene for cosmetic creams and lotions.
