Clariant has secured access to a unique technology through a strategic partnership with Plant Advanced Technologies (PAT): The French company extracts certain plant ingredients from roots.

Mit dem Gehalt an Hydrogencarbonat ändert sich, welche Wasserpflanzen in einem See leben.
The hydrogen carbonate content affects which aquatic plants live in a lake.

Deforestation and fertilizer change water ecosystems

Aquatic plants that use hydrogen carbonate as a carbon source are increasingly displacing those that use carbon dioxide.

In der Jochalge Zygnema circumcarinatum fand das Forschungsteam ein Gen, das bei der Stressbewältigung eine Rolle spielen könnte
In the Zygnema circumcarinatum alga, the research team found a gene that might play a role in stress management.

How land plants control stress

How land plants cope with stress is not primarily controlled by hormones. An international team of researchers found out that a gene set regulates the process right off the bat.

Tableware made of bamboo fibers is an alternative to plastic tableware.

Bamboo dishes: Beware of heat!

Not every bamboo coffee-to-go cup is suitable for hot food: Products made with synthetic resin release toxic substances, warns the Federal Institute for Risk Assessment.

Taucher sammeln Blätter des Neptungrases (Posidonia oceanica) in der Bucht von Calvi auf Korsika.
Divers collect leaves of Posidonia oceanica in the bay of Calvi on Corsica.

Oceans yield new antibiotics

Researchers have discovered a new source of antibiotics in the ocean. Planctomycetes are a marine phylum that has previously attracted little attention.

Kläranlagen haben oft einen hohen Flächenbedarf. Der Ruhrverband erprobt jetzt ein Verfahren, das unter anderem Fläche einspart.
The new wastewater treatment process saves space.

More efficient wastewater treatment

Sewage treatment plants often require a lot of space. The Ruhrverband is piloting a new process that saves 30% electricity and also reduces space requirements and operating costs.

Laubholzarten können den Versorgungsengpass durch Nadelholz ausgleichen
Hardwood species can compensate for the supply bottleneck of coniferous woods

Making fiberboard from hardwood

In addition to softwoods, low-value hardwoods are also suitable for the production of fiberboard. This has been demonstrated by Fraunhofer researchers.

The European Investment Bank is one of the world's largest development banks.

EIB goes green

The European Investment Bank will stop financing fossil energy projects from the end of 2021. Future funding will focus on clean energy innovation, energy efficiency and renewables.

Mechanische Unkrautbekämpfung: Spezialisten der Universität Bonn stellen einen Rollstriegel ein, der über die frisch gepflanzte Versuchsfläche kämmt, um keimende Unkräuter zu entfernen.
Mechanical weed control: Specialists from the University of Bonn adjust a roller weeder that combs over the freshly planted trial area to remove germinating weeds.

Gentle weed control

Researchers from Bonn are hoping to gently optimize weed control in the cultivation of medicinal plants in order to avoid contamination.

EU building
The Europa building in Brussels is the seat of the European Council.

Genome Editing: EU to review judgment

The European Council calls on the European Commission to investigate how the handling of genome-edited plants is to be regulated in future.

FAU-Wissenschaftler haben zusammen mit internationalen Kollegen das Rätsel um die Härte von Perlmutt (im Bild das Perlmutt einer Abalone-Schnecke) geknackt.
Together with international colleagues, FAU scientists have cracked the mystery of the hardness of nacre (the picture shows the nacre of an abalone snail).

As strong as mother-of-pearl

Researchers have shed light on the structure of nacre in mussels, paving the way for break-resistant ceramic materials.

Pestizide können bereits in geringsten Konzentrationen Wirkungen auf sensitive Individuen haben. Das zeigen auch Versuche mit Wasserflöhen.
Pesticides can have effects on sensitive individuals even at very low concentrations. This was also shown by experiments with water fleas.

Pesticides: even low doses harmful

Pesticides pose greater risks than previously thought: Helmholtz researchers have shown that pollutants can affect sensitive people and ecosystems even at very low concentrations.

Insektenarten, wie diese Kleine Goldschrecke (Chrysochraon dispar), sind in ihren Beständen deutlich zurückgegangen.
The populations of insect species such as Chrysochraon dispar have shrunk considerably.

Insects disappear faster than suspected

In Germany, most insect groups are affected by species extinction - and more so than previously assumed, as a study led by the Technical University of Munich shows.

Viele Kleinbauern in Asien und Afrika leben vom Reisanbau.
Many small farmers in Asia and Africa make their living from rice cultivation.

Tackling plant disease in rice

With two multi-resistant rice varieties and a diagnostic kit, an international team of researchers hopes to eradicate the plant disease bacterial blight.

Bei vielen Industrieprozessen fällt Kohlendioxid als Abfall an. Wirtschaftlichere Prozesse sollen dazu führen, dass das Treibhausgas stofflich recycelt wird.
Many industrial processes produce carbon dioxide as waste. More economical processes are designed to allow the recycling of the greenhouse gas.

Alcohol made from CO2

Production of alcohols from CO2 through electrochemical reduction is the goal of a research consortium that wants to use a new process to reduce the energy required for electrosynthesis.

Every year, millions of tons of plastic end up in the environment and pollute the oceans.
