After the oil is extracted from corn germ meal, the corn germ is typically fed to poultry and other livestock animals. But a new, value-added use could be on tap for this "leftover." Researchers have determined that corn germ can be used as a protein extender for plywood glues.

It might sound like the opening to a trippy fairy tale, but there are now 71 known species of bioluminescent mushrooms that glow night and day amidst the leaf litter of tropical jungles across the globe. [More]

Seven new glow-in-the-dark mushroom species have been discovered, increasing the number of known luminescent fungi species from 64 to 71. The new finds include two new species named after movements in Mozart's Requiem. The discoveries also shed light on the evolution of luminescence, adding to the number of known lineages in the fungi "family tree" where luminescence has been reported.
