Stress is unhealthy - for both humans and plants. Unlike humans or animals, however, plants cannot avoid stress, e.g., they cannot flee from heat into the shade or into cooler areas. That is why plant cells have a number of adaptation mechanisms. Researchers have now been able to show that the mechanisms in the shoot meristem are particularly effective if the plant has already survived heat.

Living organisms adapt to their respective environment as a result of evolution. This also applies to lichens, which are symbiotic communities of fungi and green algae or cyanobacteria.

What remains after harvesting usually ends up in the biogas plant and is used for energy. The resulting fermentation residues are often taken as fertilizer in agriculture because of their high nutrient content. Researchers from the German Institute of Textile and Fiber Research Denkendorf have now shown that the recycling chain for fermentation residues does not have to end in the field, but that they can be further processed in industry as a raw material.

Household sponges, mattresses, car seats or insulating walls: it is hard to imagine everyday life without foams, whether hard or soft. However, the production of the petroleum-based material is not very environmentally friendly. Researchers at Kaiserslautern University of Applied Sciences think it's time for a change: Together with partners from seven countries, the team led by polymer chemist Sergiy Grishchuk wants to make foam and composite materials more sustainable.

Almost 40% of global CO2 emissions can be attributed to the construction industry. The building sector in particular, where construction with cement still dominates, is responsible for the majority of greenhouse gases. But the industry is undergoing a transformation towards more sustainability. Visitors to the Botanical Garden at the University of Freiburg can now see for themselves how this can be done. Researchers from the universities of Freiburg and Stuttgart are presenting the livMatS pavilion here - a building constructed from flax fibers.

Smart farming solutions from a single source - that's what Bosch and BASF want to offer in the future with their joint venture Bosch BASF Smart Farming GmbH (BBSF), in which they have equal shares. The antitrust authorities worldwide have now given their approval for this. The company is headquartered in Cologne. The first markets for the Smart Spraying will be North America, South America and Europe, as the partners announced at the end of June 2021.

Whether cream or lotion: natural cosmetics are in vogue. More and more manufacturers are therefore turning to natural ingredients to respond to the growing demand. BASF Care Creations is now launching a natural ingredient for skin care products. At the end of June, the Ludwigshafen-based company announced the launch of a new biopolymer called Hydagen Clean. It is designed to replace synthetic polymers in facial care, body care and styling products. According to the company, Hydagen Clean is made from 100% natural and renewable raw materials and is biodegradable.
