Caterpillar deceives corn plant into lowering defenses against it
In a deception that likely has evolved over thousands of years, a caterpillar that feeds on corn leaves induces the plant to turn off its defenses against insect predators, allowing the caterpillar to eat more and grow faster, according to chemical ecologists in Penn State's College of Agricultural Sciences.
Only above-water microbes play a role in cave development
Only the microbes located above the water's surface contribute to the development of hydrogen-sulfide-rich caves, suggests an international team of researchers.
Water heals a bioplastic
A drop of water self-heals a multiphase polymer derived from the genetic code of squid ring teeth, which may someday extend the life of medical implants, fiber-optic cables and other hard to repair in place objects, according to an international team of researchers.
