At AAAS annual conference - Feeding the world can be a constant battle between opposing forces.
Agriculture is often seen as being in conflict with natural resources as farmers attempt to feed the world without poisoning the Earth, said Charles W. Rice, a Kansas State University soil microbiologist and professor of agronomy. Excessive tillage, low productivity, soil erosion and residue removal result in loss of soil structure, organic matter, nutrients and biodiversity.
Even greater demands will be placed on agricultural systems in the future. "Properly managed, agriculture ecosystems can provide food and energy security and provide environmental services," Rice said. "A sustainable agricultural system needs to consider the conservation of the soil and water in addition to production of food, fiber and energy."

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
Laser-driving of semimetals allows creating novel quasiparticle states within condensed matter systems and switching between different states on ultrafast time scales
Studying properties of fundamental particles in condensed matter systems is a promising approach to quantum field theory. Quasiparticles offer the opportunity...
Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
