(PhysOrg.com) -- Bacteria collected from rocks taken from the cliffs at the tiny English fishing village of Beer in Devon, have survived on the outside surface of the International Space Station for 553 days. The bacteria, ...
(PhysOrg.com) -- Scientists in the US have solved the mystery of how peat mosses manage to get their spores high enough to catch the wind, discovering that they produce vortex rings of air, like miniature "mushroom clouds" ...
By tinkering with a type of fungus that lives in association with plant roots, researchers have found a way to increase the growth of rice by an impressive margin. The so-called mycorrhizal fungi are found in association ...
