Virginia Tech has a second Amorphophallus titanum, or "corpse plant," ready to bloom and emit its intensely powerful stench. People are invited to tie bandanas over their noses and come see the rare and unusual plant.
The horticulture greenhouse containing the plant is open to visitors Monday through Friday, July 26-30, and August 2-6, from 8 a.m. to 4 p.m. The likely date for the plant to bloom is Wednesday, Aug. 4, said Scott Rapier, greenhouse manager in the Department of Horticulture in Virginia Techs College of Agriculture and Life Sciences; follow the plants progress on the web at http://www.hort.vt.edu/VTHG/ if you want to see it on the date it blooms.
Although a blooming Amorphophallus titanum, or titan arum, is rarely seen, Virginia Techs first bloomed in August 2002, drawing crowds who braved the odor and the football traffic to see it. The smelly plant is rare because it puts forth one blossom every four to 10 years. This year, the second plant, located in Virginia Techs greenhouse complex, should bloom ahead of football traffic, making it easier for the public to visit the greenhouse. The first of these plants in the United States bloomed in 1937 at the New York Botanical Garden, and since, only about 20 have bloomed in this country.

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...
