Scientific consensus is that high oxygen levels allowed these humongous fliers to exist, but a new study throws that idea ...

Insects first took to the skies about 350 million years ago, some 200 million years before birds first flapped their wings. By the end of the Carboniferous period, 300 million years ago, some flying ...

Insect wings represent a pivotal evolutionary innovation that has underpinned the remarkable radiation of the Insecta. This field, at the intersection of evolution and developmental biology (evo-devo) ...

Researchers describe, for the first time, the structure of a smell-receptor protein common among insects. Its inner architecture illuminates how insects evolved to detect an amazing diversity of odors ...

Most of the volume of epithelial cell bodies containing nuclei are aligned as a monolayer on the apical (upper) side. They extend pillarlike cell processes in a basal (downward) direction. At the ...
