At DESY's X-ray light source PETRA III in Hamburg, a team led by Swedish researchers has produced the strongest bio-material that has ever been made. The artifical, but bio-degradable cellulose fibres are stronger than steel and even dragline spider silk, which had been considered the strongest bio-based material thus far.
On May 15 and 16 an estimated 200 participants from more than 22 nations met in Cologne for the “International conference on bio-based materials". The annual conference took place for the eleventh time and was once again organised by the Nova Institute. In the more than 30 talks during the two-day event the speakers highlighted the enormous potential of bio-based materials, which is reflected by the growing product range offered by many companies.
Two years ago Bayer, mostly known as a chemical and pharmaceutical company, announced their plans to take over the US-based agriculture specialist Monsanto. The future merger caused quite the stir from the get-go, as the resulting super agro-chemical company would be the largest worldwide. With a price tag of US$62.5 billion, the takeover would also be the largest one ever to be realized by a German company.
Dry cleaners are very helpful when it comes to the stain removal off of delicate fabric. However, the chemicals used in the cleaning process are often very damaging to the environment. The average dry cleaning business produces a number of harmful waste products, including solvents, soils, carbon, dyes, grease, and powdered filter material.
There are many reasons why insects are vanishing in alarming numbers. One reason is intensive farming and the corresponding use of synthetic crop protection agents and pesticides. For instance, the widespread use of the neonicotinoids has been shown to be hazardous to the health of bees and bumblebees.
Tasty food is “mouth-watering”. However, saliva I so much more than water: It contains mucosal and immune cells as well as a large number of molecules that perform a wide variety of biological functions such as ensuring healthy teeth, gums, and oral mucosa. Moreover, saliva is the first barrier against pathogens. Therefore, it also contains a number of antimicrobial molecules, including the antibacterial lysozyme. These are part of the innate molecular immune system.
This year the Lindau Nobel Laureate Meeting takes place for the 68th time, but for the first time in the newly renovated “Inselhalle”. For the last two years the meeting took place at the city theater and thus counted fewer participants.
An initial financing round helped the founders of ECF Farmsystems GmbH realize their idea of an aquaponics farm in Berlin in 2014. Since then, the start-up has been supported by co-founder and managing director Nicolas Leschke from the "IBB Beteiligungsgesellschaft mbH".
The increasing demand for living space is driving a rethink in the construction industry. Renewable raw materials such as wood or straw are becoming increasingly important in order to conserve finite resources such as sand, an important aggregate for concrete. To make construction more sustainable, scientists at the Karlsruhe Institute of Technology (KIT) are conducting targeted research into new materials that are not only environmentally friendly but also recyclable.
Using so-called genome-editing tools such as CRISPR-Cas, the genetic material DNA can be processed as precisely as never before. The molecular tool can be used to selectively exchange or change specific sections or even individual building blocks of the DNA - the nucleotides. There are possible applications for these tools both in medicine and in agriculture: it would be much easier and faster to breed heat-resistant, pest-resistant or higher-yielding crops. In the US, some genome-edited plants are already approved for cultivation.
