In the future, cleaning robots will sniff out air pollution

Researchers at the Public Laboratory for Open Technology and Science have kitted out a Roomba -- you know, one of those robotic vacuum cleaners that cats ride around on and act out Citizen Kane -- to evaluate air quality. Lights on the Roomba indicate the presence of evaporated alcohol, and a long-exposure photo, above, can show which parts of a room are clean and which are fumey. Blue lights in the above photo mean that the robot detected polluted air.

Half of all geothermal energy is left over from birth of solar system, say scientists

Well, hello there, enormous quantities of heat that's just beneath our feet and could potentially be tapped to provide enormous amounts of base-load electricity! Where'd YOU come from? The birth of the planet, you say? No sh*t!

How a company you've never heard of could destroy the ocean ecosystem

Omega Protein, Inc. (a company you've never heard of) is quickly overfishing the Atlantic menhaden (a species you've never heard of). As a result, a number of fish that you have heard of -- striped bass, bluefish, tuna, dolphin, seatrout, and mackerel -- as well as the ocean ecosystem as a whole, the Chesapeake Bay, and the Long Island Sound (which you’ve heard of) are suffering.

Menhaden are tiny, bony, oily fish that humans can't eat, but which, according to marine scientists, are "the most important fish in the sea." Menhaden are the main consumers of phytoplankton, and without them, areas like the Chesapeake Bay and Long Island Sound are clogged with algae. They are also a staple food for bigger, tastier fish, who, deprived of menhaden, are growing sad and malnourished.

In the past 25 years, the menhaden population has shrunk from 160 billion to about 20 billion.
