Over the last decade the market has had a tendency to value food products that are healthy and safe and encourage healthy lifestyles, with the added parameter that their associated production processes are environmentally sound. In the case of systems of cattle production the current and future aim is the obtaining of a quality product within an environmentally and economically sustainable framework.
Both objectives ultimately depend on animal feeding. The composition of the diet can have repercussions both on the product quality and on the effect the system of production has on the environment; and in such a way that we can approach these objectives manipulating the general composition of the diet.
Basing ourselves on the principle that “we are what we eat” and translating it to animal production systems, we can assume that diet changes are related to changes in the quality of the product and in the environmental impact of the production process itself. It is well known that vegetable protein is poorly taken advantage of by animals, given that a large part of the Nitrogen is excreted to the surroundings. Thus, for cattle, the efficiency of conversion of vegetable protein to animal protein is less than 20% for meat and 25% for milk. Cattle farmers will have to consider new feeding strategies which take into account long- and short-term effects on the environment. All this will lead to high quality agroenvironmental systems which will confer greater commercial value to the products derived.

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.
To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...
Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
