Roots are crucial for the development of strong, healthy crops. But until recently, exactly which genes are involved in the development of roots was still a mystery. Scientists from the Flanders Interuniversity Institute for Biotechnology (VIB) connected to Ghent University have now analyzed a complete plant genome in order to identify the genes that are essential for the formation of capillary roots. For the first time, they are unraveling the genetic basis for the branching of the root system - the key to a plant’s further growth and development.
The mystery of capillary root formation
Root systems absorb nutrients and anchor plants in the soil - two crucial functions for a plant’s growth and further development. The formation of capillary roots is vital to the root system and determines how much water and minerals a plant can absorb. As early as 1937, scientists knew that it takes only 4 months for a single rye plant to produce some 13 million individual roots! But up to now, the genetic basis of this complex process has remained unexplained.

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.
Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...
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...
