The shape of a bird's wing determines where it lives

Bird's wings generally become shorter and more rounded the closer they live to the equator. Birds with smaller wings are to a greater extent restricted to stay in the same area, because their wings have not evolved for long ...

Morphing metal shapes future of soft robotics

Imagine an aircraft that could alter its wing shape in midflight and, like a pelican, dive into the water before morphing into a submarine. Cornell University engineering professor Rob Shepherd and his group might help make ...

High-tech bird watching for shapeshifting airplane wings

An international team of engineers and biologists will gain unprecedented insights into how birds fly so efficiently and then turn that knowledge to building unmanned aircraft with shapeshifting wings.

New insight into leaf shape diversity

Many of us probably remember the punnett squares by which we were introduced to the idea of genetic inheritance in school: a dominant allele in each of my brown-eyed parents hides a recessive allele that explains my blue ...

Shape of bird wings depends on ancestors more than flight style

In a finding that could change the way scientists think about bird evolution, researchers have found that the shape of bird wings is influenced more by how closely related species are to one another than by flight style.
