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.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...

Physicists in the Laboratory for Attosecond Physics (run jointly by LMU Munich and the Max Planck Institute for Quantum Optics) have developed an attosecond electron microscope that allows them to visualize the dispersion of light in time and space, and observe the motions of electrons in atoms.
The most basic of all physical interactions in nature is that between light and matter. This interaction takes place in attosecond times (i.e. billionths of a...
