A team of zoologists, molecular engineers and pest control specialists at the Chinese Academy of Sciences, working with a small team of colleagues from Peking University, has identified some of the enzymes and precursor compounds involved in the biosynthesis of 4VA in locusts. In their study, published in the journal Nature, the group conducted genetic deactivation on sample locusts to find the precursors to the biosynthesis of 4VA, a pheromone that induces swarming in the insects.

An international team of scientists with a variety of backgrounds has found evidence that a boomerang found in a cave in Poland decades ago may be the oldest one ever reported. In their study published on the open-access site PLOS One, the group analyzed artifacts found near the boomerang to learn more about its age. In 1985, a team of archaeologists working at a dig site inside Obłazowa Cave in Poland found, among other things, a 72-cm-long boomerang.

A team of bio-robotic specialists at the Max Planck Institute for Intelligent Systems has confirmed theories suggesting that scaly-tailed flying squirrels use their spiky tails to keep their perch in slippery trees. In their study published in the Journal of the Royal Society Interface, the group generated 3D models of the squirrel tails and tested their friction on ramps with different grades of sandpaper.
