A robust, new geographic information systems (GIS) software tool developed by a University at Buffalo geographer is helping the U.S. Forest Service to more quickly and accurately assess and contain the devastation wrought by forest fires, such as last summers Hayman Fire, Colorados worst wildfire ever. That fire, which covered more than 137,000 acres and blazed for more than two weeks, destroyed 133 homes and caused damage of approximately $39 million.
The new tool, to be presented in New Orleans on Thursday (March 6, 2003) at the annual meeting of the Association of American Geographers, modifies a computer model developed originally by the U.S. Agricultural Research Service that is used to assess soil erosion in agricultural areas.
"Last years devastating forest-fire season has prompted forest, wildlife and watershed managers to call for better ways of rapidly assessing how fires have impacted soil erosion and sediment delivery in streams," said Chris Renschler, Ph.D., assistant professor of geography in the UB College of Arts and Sciences.

A novel mechanism for electron optics in two-dimensional solid-state systems opens up a route to engineering quantum-optical phenomena in a variety of materials
Electrons can interfere in the same manner as water, acoustical or light waves do. When exploited in solid-state materials, such effects promise novel...
Biochemists at Martin Luther University Halle-Wittenberg (MLU) have used a standard electron cryo-microscope to achieve surprisingly good images that are on par with those taken by far more sophisticated equipment. They have succeeded in determining the structure of ferritin almost at the atomic level. Their results were published in the journal "PLOS ONE".
Electron cryo-microscopy has become increasingly important in recent years, especially in shedding light on protein structures. The developers of the new...
New insight into the spin behavior in an exotic state of matter puts us closer to next-generation spintronic devices

Kiel physics team observed extremely fast electronic changes in real time in a special material class
In physics, they are currently the subject of intensive research; in electronics, they could enable completely new functions. So-called topological materials...
Solar cells based on perovskite compounds could soon make electricity generation from sunlight even more efficient and cheaper. The laboratory efficiency of these perovskite solar cells already exceeds that of the well-known silicon solar cells. An international team led by Stefan Weber from the Max Planck Institute for Polymer Research (MPI-P) in Mainz has found microscopic structures in perovskite crystals that can guide the charge transport in the solar cell. Clever alignment of these "electron highways" could make perovskite solar cells even more powerful.
Solar cells convert sunlight into electricity. During this process, the electrons of the material inside the cell absorb the energy of the light....
