    A new blacker-than pitch material could help scientists gather hard-to-obtain scientific measurements or observe unseen astronomical objects like Earth-sized planets orbiting distant stars. The technological advancement could thereby aid astrobiologists in the search for habitable, extrasolar worlds.

    New research shows that temperature has a greater effect on the rate of some chemical reactions than previously thought. The study indicates that certain reactions necessary for life could have happened faster on a warm Earth, reducing the time necessary for evolution to occur.
