The production of meat from animal muscle cells in a bioreactor is a promising way of securing the supply of protein-rich food for the world's growing population without harming the environment and climate. The first cell-based meat products have already been authorised in Singapore and the USA. What is possible on earth could also enrich space missions. This is shown by initial investigations by two independent research teams from the European Space Agency (ESA) in Germany and the UK, who have tested the cultivation of cultured meat in space.

Insects have long been part of the diet in many countries. They are not only rich in proteins, minerals and vitamins. They are also relatively easy to keep and produce significantly fewer greenhouse gases than pigs or cattle.

The Federal Ministry of Education and Research (BMBF) is investing around 50 million euros in innovative plant breeding research that is open to technology and methods as part of a new funding measure. The aim is to be able to guarantee a reliable, climate-resistant supply of high-quality, healthy and safe food.

The number of hot days with air temperatures of at least 30 degrees Celsius has been increasing in Germany for years as a result of climate change. This is documented by long-term records of the German Weather Service. In contrast, there is hardly any data on the temperature development in the ground, as the measurements are very complex. In a project coordinated by the Helmholtz Centre for Environmental Research (UFZ), a team of researchers has now examined the development of ground temperature in more detail.

In nature, each plant competes for the best growing conditions. They are therefore confronted with diverse and changing environmental influences and usually grow in less densely packed neighborhoods than cultivated plants in the open. In addition to environmental conditions that are as uniform and stable as possible, there is also a certain amount of shading by neighboring plants due to plant density. Researchers at the IPK Leibniz Institute have now shown that a plant's selfish characteristics are often detrimental to agriculture.

It is the single largest investment in Bayer's crop protection business in 40 years and a clear commitment to the site in Monheim: the Leverkusen-based company plans to spend EUR 220 million to build a new research and development center here, thus strengthening its commitment to sustainable agriculture. In the presence of North Rhine-Westphalia's Minister President Hendrik Wüst, the construction site for the new buildings in Monheim was opened at the end of August with the traditional groundbreaking ceremony.

Leaf fleas are a horror for fruit growers. The so-called psyllids sting the plant with their sucking mouthparts and suck out the plant sap. In this way, the parasitic leaf fleas sometimes cause high crop losses. Until now, fruit growers have tried to control the pest with the help of synthetic chemical pesticides. An international team of researchers with the participation of the Julius Kühn Institute (JKI) has now, by chance, found a suitable antagonist in a parasitic fungus to eliminate the leaf flea in fruit growing in a natural way.

Wheat is one of the most important foods in Germany. According to the Federal Statistical Office, 22 million tons of winter wheat were harvested in Germany last year - around five percent more than the year before. But the grain is sensitive to environmental influences, as the past heat years have shown. In Hesse alone, a third of the harvest was lost to heat and drought in 2018. Technology, fertilizers and artificial irrigation also reached their limits.
