Giant Thai insect reveals clues to human heart disease

An electron microscope has been used to capture the first three-dimensional image of a tiny filament, or strand, of an essential muscle that the palm-sized water bug Lethocerus indicus uses to fly. This image shows, for the first time, the individual molecules in the filament in a relaxed state, which is necessary to re-extend muscles.

First evidence of deep-sea animals ingesting microplastics

Scientists working in the mid-Atlantic and south-west Indian Ocean have found evidence of microfibers ingested by deep sea animals including hermit crabs, squat lobsters and sea cucumbers, revealing for the first time the environmental fallout of microplastic pollution.

Lake brownification, eutrophication decrease the content of essential fatty acids in fish used in...

Eutrophication and brownification change phytoplankton community structure and decrease the production of essential omega-3 fatty acids in lakes. Perch growing in oligotrophic clear-water lakes contain 1.5-1.9 times more essential omega-3 fatty acids than those grown in eutrophic and brown-water lakes.

Advancing non-animal testing methods: First set of novel knowledge tools published

An adverse outcome pathway, or AOP, is a highly structured way of describing a toxicological process which can lead to an adverse health effect in humans or wildlife, caused by an unsafe exposure to a chemical substance. The first five adverse outcome pathways have now been published by experts. The AOPs are novel knowledge management tools in toxicology and are useful for supporting risk assessment to human health. They are also valuable for helping to avoid animal testing through the use of alternative methods.

Genetically engineered crops are safe, review of studies finds
