Long-moustached short-moustaches: a transitional form between mosquitoes and flies was found in the Triassic

2023-09-15 11:38 The order Diptera includes, as the name implies, insects with only one pair of wings. The body structure of diptera can be reduced to two main types: mosquitoes with multi-lobed antennae and flies with three-lobed antennae. This difference was noticed a long time ago: diptera were divided into long-whiskered Nematocera and short-whiskered Brachycera in the first half of the XIX century. But as often happens...

3D-Printed ‘Living Material’ Could Clean Up Contaminated Water

2023-09-08 18:58 Researchers at the University of California San Diego have developed a new type of material that could offer a sustainable and eco-friendly solution to clean pollutants from water.
