“Global warming can explain part of this trend,” Dr. Staudt said, “because it is feeding longer fire seasons, drier conditions, and more lightning. According to recent studies, the fire season stretches about 78 days longer and individual fires last about 30 days longer.”
"Increased Risk of Catastrophic Wildfires: Global Warming’s Wake-Up Call for the Western United States" details how:• Global Warming Makes Forests More Susceptible to Fire
The increase in big wildfires comes with increased losses and escalating costs to fight these fires. Property losses from wildfires have averaged more than $1 billion over the past decade. Annual federal government expenditures on fire fighting in 2007 were $3 billion, up from about $1 billion in 1999, and typically less than half that for the 1970s, 1980s, and early 1990s. The U.S. Forest Service now spends 45 percent of its annual budget on fire prevention and suppression, up from 20 percent in 2000.
Today’s new era of more frequent and intense fires demands new approaches to managing our forests and fire risk. “We must get at the root of the problem and reduce the global warming pollution that fuels more frequent and severe fires,” Dr. Staudt said. At the same time, it is critical to return our forests to more natural conditions and fire-cycles, step up protections for people and properties, and prepare to jumpstart new forest growth.

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).
Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...
Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.
The cells of the mouth, nose and intestinal mucosa produce large quantities of a chemical called sialic acid. Many bacteria possess a special transport system...

Fiber-reinforced plastics (FRP) are frequently used in the aeronautic and automobile industry. However, the repair of workpieces made of these composite materials is often less profitable than exchanging the part. In order to increase the lifetime of FRP parts and to make them more eco-efficient, the Laser Zentrum Hannover e.V. (LZH) and the Apodius GmbH want to combine a new measuring device for fiber layer orientation with an innovative laser-based repair process.
Defects in FRP pieces may be production or operation-related. Whether or not repair is cost-effective depends on the geometry of the defective area, the tools...
