The aim of Navarre engineer Ana Zabalza Aznárez’s PhD thesis - entitled “The inhibition of the biosynthesis of amino acids in ramified chain and their use as a target-site for herbicides” - was to find out what effects herbicides produce on the metabolism of plants so as to enable a more rational use of them.
According to lecturer Zabalza Aznárez, herbicides have undergone considerable development since they began to be developed in the fifties of the last century in order to eliminate weeds which interfered with crop cultivation. Amongst the great variety of existing herbicides, affecting different aspects of the metabolism of plants, the authoress of the thesis has analysed those which inhibit the biosynthesis of amino acids in ramified chain.
These herbicides were discovered in the eighties and have experienced great success in the market, given their high effectiveness. Moreover, as they are applied in very small doses to crops, they have a minimum toxic effect amongst animals, given that inhibition of the biosynthesis of amino acids in ramified chain is a process which only takes place in plants and microorganisms, and is why these herbicides do not attack animals.

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
