Seagrass removes carbon dioxide (CO₂) from the atmosphere more sustainably than previously thought. This is the conclusion of a study published in the journal Nature Ecology & Evolution, which examined seagrass meadows off the island of Elba.

Climate change and species extinction are considered the two greatest global crises of our time. An international study published in the journal "Global Change Biology" shows that both problems can often be combated with the same measures. In the study, experts show that 14 of the 21 species protection targets that the United Nations is expected to adopt at the UN Conference on Biological Diversity in Kunming in the fall of 2022 will also greatly slow down global warming.

Nature is once again the model: Many chemical reactions require a lot of energy to take place quickly or even at all. Living cells have solved this by enzymes that act as catalysts for the reactions. Often, these enzymes carry metal ions in their reactive center. A new research alliance now wants to mimic this principle in order to reduce the need for energy and raw materials for important chemical reactions. The project, called BioOxCat, is funded by the German Research Foundation with 3.3 million euros for four years.

Even though more and more people are adopting a vegetarian or even vegan diet, for many, meat products are still an integral part of their daily diet. In the EU alone, per capita consumption is around 80 kilograms of meat per year. For a long time now, it has not only been environmental organizations that have been campaigning for a reduction in meat consumption and pointing out the consequences of animal husbandry. Numerous studies have also established that eating less meat is not only healthy, but also sustainable.

By 2045, Germany wants to become climate-neutral. This means that no more CO₂ is to be emitted than can be absorbed by forests or other means. To achieve this goal, the German government is relying, among other things, on the expansion of renewable energies, and this includes wind turbines (WT). With the discontinuation of EEG subsidies last year, the first wind turbines have already been taken out of operation after 20 years. However, wind turbines contain valuable raw materials that have so far been insufficiently recycled.

42% of Europe's land area is covered by forests. However, many forests, especially woodlands, are not in good condition, and climate change is exacerbating existing problems. Yet forests, as CO2 sinks, are important allies in the fight against the climate crisis. The interdisciplinary research project ONEforest is therefore developing management concepts for the most important European forest types that meet the challenges of climate change.

With the Green Talents competition, the German Federal Ministry of Education and Research has been promoting the exchange of innovative green ideas and the emergence of international collaborations since 2009 - because the challenges of the future can only be met together. Under the patronage of Federal Research Minister Bettina Stark-Watzinger, the competition has now entered a new round. Young researchers can apply to the Green Talents - International Forum for High Potentials in Sustainable Development 2022 with their ideas for a sustainable future.

Bioethanol is a bio-based alternative to petroleum-based fuels or fuel blends. A European research network with the participation of the University of Hohenheim has developed an experimental project whose process is even supposed to be more climate-friendly than merely climate-neutral. The focus is on the giant grass Miscanthus × gigantheus and the storage of carbon dioxide (CO₂). 

Apples are healthy and yet people with an apple allergy have to avoid them because of unpleasant symptoms. Various allergenic ingredients cause a burning sensation in the mouth and throat when biting into an apple, make the tongue and lips swell or cause numbness. The good news is that in just a few years there could be apples in the supermarket that allergic people can enjoy without any problems.
