Researchers from Imperial College, England have just shown in a forthcoming article in the journal Ecology Letters, that insect larvae can use an engineered toxin (Cry1Ac) as a supplementary food source.

They found that toxin-resistant larvae of the Diamondback Moth developed faster and had a greater pupal weight in the presence of the toxin. This could be a genetic effect, linked indirectly to the presence of a resistance allele but more simply, could be due to resistant insects enhancing

Tube worms living at deep-sea oil seeps in the Gulf of Mexico significantly alter their habitat, similar to beavers altering the flow of a river. Researchers from Pennsylvania State University have just published an important finding in the journal Ecology Letters.

A computer model of tube worm aggregations was created for Lamellibrachia luymesi, which is among the longest lived animals known. Both actual and model populations persist for centuries and take up high quantities of sulfide fro

Hydroelectric power provides 16 per cent of Europe’s electricity, but most of the plants and their turbines were designed many years ago. By redesigning the runner – the propeller-like component that transfers energy from the water to the drive shaft in the turbine – EUREKA project FLINDT enables operators to harness more power from their turbines.

According to Professor François Avellan, Director of the Swiss main project partner, Laboratoire de Machines Hydrauliques de l’ EPFL, Ecole poly

An advanced technique for analysing radar images shows tremendous promise for scientists studying forests, agriculture, ice and other terrain types, but experts at a recent ESA workshop cautioned that research work is needed before practical applications can be developed.

More than 120 scientists and researchers from 20 countries gathered recently at ESA’s ESRIN facility in Frascati, Italy, for a three-day workshop to share the latest results on scientific tests and potential applications of

Mayo Clinic researchers have proven for the first time that cells produced by the bone marrow can form new heart-muscle cells in adults, providing an important boost to research that could enable the body to replace heart muscle damaged by heart attack. The findings are now available online and will be published tomorrow in Circulation: Journal of the American Heart Association.

“Until recently, the heart has been seen as an organ that cannot be healed,” says Noel Caplice, M.D., the Mayo Cli

North Carolina State University poultry scientists have developed a powerful new tool to aid the understanding of how chicken embryos develop.

The research of Dr. Paul Mozdziak, assistant professor of poultry science, and Dr. James Petitte, professor of poultry science, resulted in successfully transferring a gene into a chicken and establishing a line of chickens carrying that specific marker gene.

Currently, the chick embryo is often used as a model to understand normal a
