Life & Non-humans

If you were a hungry predator of a leafhopper, you might have a problem: thanks to a nanoparticle known as brochosomes that the insects produce, you probably can't see it, even sitting out in the open on a leaf. Now, researchers at Penn State have discovered a way to create synthetic versions of these brochosomes at scale, potentially enabling such technologies as invisibility cloaks and precision sensors.

A developing Drosophila embryo was recorded using light sheet microscopy. The embryo is segmented, tracked, and reconstructed. Cell boundaries show how individual cells fold, divide, and rearrange.

Nine years after the 2012 High Park Fire burned a stand of lodgepole pine that had been severely affected by the mountain pine beetle, lodgepole and aspen saplings were rebounding on this slope in the Arapaho and Roosevelt National Forests. A CSU-led study has found that forests are not regenerating fast enough to keep pace with climate change, wildfire, insects and disease. Photo by Katie Nigro, September 2021

Repurposing natural joints for robotics involves several key ideas. First, engineers take a joint from a real animal and use its shape and movement as the basis for a robot design. Second, they study the two main parts of the exoskeleton, the hard shell and the flexible joint tissue, to understand how each contributes to strength and movement. Third, they build bio-hybrid robots by combining natural structures with added features, such as parts that move on their own, parts that boost motion, and protective coatings. Finally, these designs can be used in many types of robots, including gripping tools, swimming or walking systems, and devices that move very quickly.
