Nanoparticles working in harmony

For decades, researchers have been working to develop nanoparticles that deliver cancer drugs directly to tumors, minimizing the toxic side effects of chemotherapy. However, even with the best of these nanoparticles, only ...

'Safer' pesticide could create toxic mercury, study says

A compound in pesticides that replaced another banned for its harmful effects, may threaten humans and wildlife by reacting with mercury in natural water to form a toxic chemical, researchers said Tuesday.

Pesticides hit bumblebee reproduction

House sparrow decline linked to air pollution and poor diet

Despite being well-adapted to urban life, house sparrow numbers are falling. A study in open-access journal Frontiers in Ecology and Evolution finds that compared to sparrows living in the country, urban-dwelling birds show ...

More efficient risk assessment for nanomaterials

Nanotechnology is booming, but risk assessment for these tiny particles is a laborious process that presents significant challenges to the German Federal Institute for Risk Assessment (BfR). To find more efficient test methods, ...
