The engineered eggplant expresses a natural insecticide derived from the bacteria Bacillus thuringiensis (Bt), making it resistant to the fruit and shoot borer (FSB), a highly destructive pest. The tiny larvae account for up to 40 percent of eggplant crop losses each year in India, Bangladesh and the Philippines, and other areas of South and Southeast Asia.
The work on the resistant eggplant is part of the Agricultural Biotechnology Support Project (ABSP) II, which is funded by the U.S. Agency for International Development and administered by Cornell in partnership with Sathguru, a firm associated with Cornell's College of Agriculture and Life Sciences (CALS).
Cornell researchers from plant breeding, entomology, molecular biology, applied economics, communication, international programs and the Cornell Center for Technology Enterprise and Commercialization began collaborating on the development of the Bt eggplant in 2002. Another partner, Maharashtra Hybrid Seeds, is on schedule to commercialize the genetically modified fruit by 2009."Cornell has worked effectively to facilitate a productive partnership between the public and private sectors that will make this technology available to eggplant producers at every economic level," said Ronnie Coffman, international professor of plant breeding and genetics and director of International Programs in CALS.
All the safety tests for the Bt eggplant have been conducted in India, starting in greenhouses and now moving to large-scale field trials. The eggplant has been found to be nontoxic to fish, chickens, rabbits, goats, rats and cattle as well as nonallergenic. Ongoing tests will examine such questions as whether the plant will continue to resist FSB in the field and for how long; whether the Bt eggplant cross pollinates with other eggplants in the field and how far the Bt plants should be from other eggplant fields; whether nontarget insect populations are affected in the long term; and how yields compare with those of other eggplant varieties.
It is estimated that the Bt eggplant will reduce insecticide use by 30 percent while doubling the yield of marketable fruit (although eggplant is eaten as a vegetable).
Eggplant is a popular crop in the subtropics and tropics, especially in India and Bangladesh, where it is grown on about 1.5 million acres.
India and Bangladesh together expect to plant 110,000 acres of the FSB-resistant eggplant commercially by the end of 2010 and 650,000 acres by 2015. Economists from Cornell and other institutions report that the Bt eggplant would result in lower prices for consumers, higher yields for farmers and, by 2015, boost the Indian economy by $411 million and the Bangladeshi economy by $37 million.
"In spite of the green revolution in India, agricultural growth has stagnated there to less than 2 percent per year," said Raman. "It is important for a land-grant university like Cornell to be engaged in the improvement of technologies and help create a road map that leads to agricultural and economic growth in places like South and Southeast Asia and Africa."

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...
