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.

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,...

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.
Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
