Dr. Alfred "Ernie" Schuyler, emeritus curator of botany at the Academy of Natural Sciences and a world expert on rare plants, recently was honored when a colleague discovered a new species of lichen and named it after him. The barely visible lichen (LIE kin), Vezdaea schuyleriana, is known to exist on a single boulder in rural central Pennsylvania, northwest of Lewisburg—and nowhere else in the world.
James Lendemer, a doctoral student at The New York Botanical Garden and a research associate at the Academy, is among the relatively few scientists devoting their research to lichens. In the March 2011 issue of Notulae Natureae, Lendemer announced he named his newly discovered lichen after his Academy colleague and friend, Dr. Schuyler. Lendemer studied and curated lichens in the Academy's herbarium before going to New York. The Academy's lichen collection is among the oldest in North America and contains more than 25,000 specimens.
Some lichens are important indicators of environmental quality. Because they are sensitive to air pollution, declining populations can be a clue to degraded air quality. Lichens also are a source of food for animals, and they help in the weathering process of turning rocks into soil.
"There is a lot we don't know about lichens because so few people study them, and minute lichens are rarely collected and studied," said Schuyler. "Who is going to search for more Vezdaea schuyleriana? It's so rare, it may never be seen again."
Founded in 1812, the Academy of Natural Sciences is America's oldest natural history museum and a world leader in biodiversity and environmental research. For nearly 200 years, the Academy has carried out its mission to encourage and cultivate the sciences, exploring the remarkable diversity of our natural world and sharing these discoveries with the public through innovative exhibits, publications, and educational programming.

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...

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...
