Molecular structures are the building blocks of every organism. But because of their minute size, they are extremely difficult to visualize. A team of Dortmund-based researchers headed by Leif Dehmelt at the Technical University and Yaowen Yu at the Chemical Genomics Center of the Max Planck Society developed a new method to depict the inner workings of a cell.
Half of the total global carbon dioxide stock is stored within the tropical vegetation, which only serves to worsen the consequences of tropical deforestation. Every year approximately 1,000 million metric tons of carbon dioxide are released due to deforestation. However, instead of complete forest removal, oftentimes the forests are fragmented into many smaller forest-areas.
The genome-editing tool CRISPR-Cas is one of the most groundbreaking developments for the field of molecular biotechnology throughout the last decades. Researchers worldwide are free to use this tool. However, the economical use is another matter: companies have to acquire licences from the institutes that patented the innovation.
Amsilk GmbH is the world’s first industrial supplier of synthetic silk biopolymers and aims to make the new uber-material available for use in medical or technical products as well as cosmetics. The Martinsried-based start-up engineered bacteria to produce the spider silk polymer. Those microbes are now producing the coveted proteins in large quantities. Using this white protein powder the bioengineers even manage to produce synthetic fibres.
Without a doubt, salmon is one of the most popular edible fish of all. Ever more and bigger salmon farms and aquacultures are being build to manage the demand – but not without risk for the environment. For years, Chile has been ranked second behind Norway in the list of key salmon producers worldwide. The country produces approximately 820,000 tonnes of salmon with a total value of about five billion US dollars. How does this mass production affect the environment?
Nano-technicians can construct fascinating structures with the double-stranded DNA molecule. Based on the principle of base-pairing, distinct DNA sections can be programmed to interact with other DNA segments. This method allows for the construction of molecular nanostructures. In recent years this so-called “DNA-Origami”-technique has gained more and more recognition. If the DNA is programmed accordingly, the molecule will even morph into three-dimensional nano-building blocks and nano-machines.
The 2030 Agenda for Sustainable Development established a number of agricultural goals regarding eco-friendly economic practices. However, especially the developing world is faced with decreased cost-efficiencies during the implementation of the environmentally-sound production processes. In order to address these issues, 40 ministers, CEOs, high-level representatives of UN agencies, nongovernmental organizations and trade unions, as well as more than 300 sustainable development experts gathered in Berlin.
Beer is not a new invention. In 6000 BC the Sumerians already established the first beer-like drink in Mesopotamia. At that time, the people put some bread in the water for a few days, producing an alcoholic concoction. Today, brewing takes place in huge fermenters made of steel. The starch in malted barley is converted into sugar by enzymes. This solution is fermented with hops and yeast.
Forests as a resource and ecosystem offer countless opportunities and possible applications. Unfortunately, oftentimes many of these are not compatible. Therefore it is particularly important to develop intelligent plans and policies in order to protect the forest as an ecosystem and as a home for numerous animal- and plant-species, while simultaneously being used as a sustainable resource.
Although the demand for a bio-based industry is continually growing, financial support for such endeavors is still incredibly difficult to come by. This is particularly challenging as biotechnological production processes are often times still more expensive than conventional processes.
