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.

A newly developed laser technology has enabled physicists in the Laboratory for Attosecond Physics (jointly run by LMU Munich and the Max Planck Institute of Quantum Optics) to generate attosecond bursts of high-energy photons of unprecedented intensity. This has made it possible to observe the interaction of multiple photons in a single such pulse with electrons in the inner orbital shell of an atom.
In order to observe the ultrafast electron motion in the inner shells of atoms with short light pulses, the pulses must not only be ultrashort, but very...
A group of researchers led by Andrea Cavalleri at the Max Planck Institute for Structure and Dynamics of Matter (MPSD) in Hamburg has demonstrated a new method enabling precise measurements of the interatomic forces that hold crystalline solids together. The paper Probing the Interatomic Potential of Solids by Strong-Field Nonlinear Phononics, published online in Nature, explains how a terahertz-frequency laser pulse can drive very large deformations of the crystal.
By measuring the highly unusual atomic trajectories under extreme electromagnetic transients, the MPSD group could reconstruct how rigid the atomic bonds are...

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...
