The retreat of coastlines due to rising sea levels may be accelerated by wildfires, a Duke University researcher has discovered. In the absence of such fires, forests can slow the encroachment, he found. At such fire scenes, though, finger-like patches of marshlands can extend into former forest by as much as several hundred yards. The result is a "punctuated" near-shoreline landscape, the scientist said. Such punctuated advance of the sea is in sharp contrast to the widespread belief that coastal change would be gradual due to sea-level rise.
The researchers findings about the impact of wildfires raise questions about whether fire suppression or controlled periodic burning are the best strategies in areas being gradually inundated by rising seas resulting from global warming, said Benjamin Poulter. He is a research scientist at Dukes Nicholas School of the Environment and Earth Sciences as well as a visiting lecturer at the University of North Carolina at Chapel Hill.
Poulter will describe his findings during a 5:45 p.m. talk on Thursday, Oct. 20, 2005, during an Estuarine Research Federation conference at the Marriott Waterside Hotel and Convention Center in Norfolk, Va. His research was mostly funded by NASA.

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.
Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...
In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

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...
