Insects disappear faster than suspected

That insect decline and species extinction are a fact has been shown by numerous national and international studies. Now German scientists are once again drawing attention to the loss of species with a large-scale biodiversity study. A research team led by the Technical University of Munich (TUM) has come to the conclusion that the decline of insects in Germany is even more extensive than previously assumed. "Previous studies [...] either focused exclusively on biomass, i.e. the total weight of all insects, or on individual species or species groups.

Tackling plant disease in rice

In many countries of the world, rice is a staple food. Small farmers, especially in South Asia and Africa, live from the cultivation of this important crop. However, their livelihood and food security are threatened by the plant disease bacterial blight. This is caused by the pathogen Xanthomonas oryzae pv. oryzae (Xoo). In India alone, the bacterium causes annual harvest losses worth around 3.6 billion dollars.

Making fiberboard from hardwood

Wood is a diverse raw material. It is used as a building material and fuel, for furniture construction, but also for the production of biofuel and sustainable chemicals. But climate change is putting forests under increasing pressure as a source of raw materials. Coniferous woods such as spruce in particular have suffered from drought and heat in recent years, which has severely decimated the tree population in some regions of Germany. Such supply bottlenecks are a concern for the wood processing industry.

Genome Editing: EU to review judgment

The genetic engineering ruling of the European Court of Justice in the summer of 2018 has political repercussions: the European Council, the EU's leading political body, has asked the EU Commission to clarify how "novel genomic techniques" are to be legally classified and regulated in the future. The results of this study are to be presented by April 2021 - including proposals and an impact assessment.

More efficient wastewater treatment

When factories and municipalities use water, it is usually polluted. Before it can be returned to the environment, it usually passes through a sewage treatment plant. However, sewage treatment plants represent a considerable cost factor, especially for smaller municipalities. The Ruhrverband is therefore testing a new process from the Netherlands in the Sauerland region that uses smart microbiological cleaning to significantly reduce space requirements, electricity consumption and operating costs.

Gentle weed control

Peppermint, lemon balm, wolf’s bane or chamomile are popular medicinal plants. They are used to soothe the symptoms of diseases in teas, but also in pharmaceuticals. But their cultivation is difficult. Even the smallest contamination by weeds can impair the effect of the medicinal plants. In the joint project Optimech, a team led by the University of Bonn is now investigating how medicinal plants can be cultivated in a way that is as soil-friendly as possible without having to use herbicides.

As strong as mother-of-pearl

The mother-of-pearl inside a shell is not only beautiful to look at, it has also fascinated materials researchers for decades because of its exceptional toughness. It is considered one of the most resilient materials in the world. “Nacre is the prototypical supermaterial,” the researchers, including scientists from the Friedrich Alexander University Erlangen-Nuremberg (FAU), write.

Oceans yield new antibiotics

The search for new active ingredients for the production of antibiotics is going strong. A promising source is the sea. Many microorganisms that have the potential to produce antibiotics settle here. With the marine phylum Planctomycetes, an international team of researchers has now identified a new source of active substances. Initial analyses suggest that these microorganisms, which have so far received little attention, are actually able to produce antibiotics.
