New Solar System Formation Models Indicate That Jupiter's Foray Robbed Mars of Mass
ScienceDaily (June 5, 2011) — Planetary scientists have long wondered why Mars is only about half the size and one-tenth the mass of Earth. As next-door neighbors in the inner solar system, probably formed about the same time, why isn't Mars more like Earth and Venus in size and mass? A paper published in the journal Nature provides the first cohesive explanation and, by doing so, reveals an unexpected twist in the early lives of Jupiter and Saturn as well.

Bugs Might Convert Biodiesel Waste Into New Fuel
ScienceDaily (Jan. 28, 2011) — A strain of bacteria found in soil is being studied for its ability to convert waste from a promising alternative fuel into several useful materials, including another alternative fuel.
A graduate student at The University of Alabama in Huntsville is developing biological tools to make products from crude glycerol -- a waste material from the production of biodiesel. The research is being funded by the National Science Foundation.
Disposing of glycerol has been a problem for the biodiesel industry, according to Keerthi Venkataramanan, a student in UAHuntsville's biotechnology Ph.D. program. "Many companies have had problems disposing of it. The glycerol you get as a byproduct isn't pure, so it can't be used in cosmetics or animal feeds. And purifying it costs three times as much as the glycerol is worth
