This dune, which dates to the nation’s founding and contains 400-year-old trees, is in an urban setting, with a road on one side and a school on the other.
Jeffrey Kirwan, associate professor of forestry and Extension specialist at Virginia Tech’s College of Natural Resources, has been advising students and teachers at Ocean View Elementary School in Norfolk, Va., to save what appears to be the last mature dune in Norfolk on the southern shore of the Chesapeake Bay.
The dune, which has an elevation of 70 to 85 feet, has historic significance. Some of the trees on the site were present at the time of the Sarah Constant landfall in 1607 and are the only living things that can provide a linkage between the past and present. The first settlers of Jamestown landed there. A rare plant for Virginia, upland laurel oak, also has been found on the dunes.
Kirwan first visited Ocean View Elementary through Project Learning Tree, a statewide tree-identification project for which he encourages students to do tree inventories and set up tree lists on the web. The students and teachers at Ocean View asked Kirwan if he could help to save the dune located near the school.

New 3-D model predicts best planting practices for farmers

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
