Dolphins, long considered the second-smartest species on the planet, recognize one another by name, possess a distinct concept of "self’ and, it turns out, have some surprisingly good ideas about techniques for keeping the hulls of maritime ships clean.
Karen L. Wooley, Ph.D., professor of chemistry at Washington University in St. Louis, has noted the shape and texture of dolphin skin and how it naturally prevents marine creatures from clinging to dolphin skin. The observation fits into her study of finding ways to mediate interactions between biological systems and synthetic materials, designing chemical "functionalities," or groups of atoms, that either promote or discourage binding between them.
In one recent example, Wooley and collaborator John-Stephen A. Taylor, Ph.D., Washington University professor of chemistry, hope to employ nanoparticles that will take advantage of naturally occurring chemical interactions to deliver therapeutic drugs directly to diseased cells. At the same time, Wooley currently is developing a group of nontoxic "antifouling" coatings that may one day inhibit marine organisms such as barnacles, tube worms and zoo spores from attaching to, say, the hulls of ships.

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

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...
