Your principal incentive to recycle? That one's a no-brainer: the environment, of course. But, it doesn't just have to be a green act of good will; it can add a little extra cash to your wallet as well. Recycling for money sure won't make you a millionaire, but these days every penny counts. So, cash in on your good conscience with these items.

15 Best Foods to Boost Your Metabolism

But in recent years, environmentalists have branded corn as an icon of unsustainable agriculture. It requires large amounts of fertilizer and pesticides, both of which require large amounts of fossil fuel to manufacture. Most of the resulting corn is fed to livestock who didn't evolve to subsist entirely on corn. In cattle, eating corn increases flatulence emissions of methane - a potent greenhouse gas - and creates an intestinal environment rich in e. coli, a common cause of food poisoning.

Is it easy to hit a home run in the major leagues?

A physical analysis of a player's movements, combined with a knowledge of the correct forces to apply at the right time, can be used to make a good player better. Scientific analysis like this is used in many sports, from figure skating to baseball

A European spacecraft will begin its quest this week to make the most detailed global map of the Earth's gravity field.

A brief video on the sizes of the planets to scale and several known stars

We are a group of MIT students seeking to share the artistic aspects of science with others. On Sept. 2, 2009, we launched a digital camera into near-space to take photographs of the earth from high up above. All on a 150 USD budget.

Saturn's tiny, icy moon Enceladus has recently been visited by NASA's Cassini orbiter on several very close approaches - once coming within a mere 25 kilometers (15 miles) of the surface. Scientists are learning a great deal about this curious little moon. Only about 500 kilometers wide (310 miles), it is very active, emitting internal heat, churning its surface, and - through cryovolcanism - ejecting masses of microscopic ice particles into Saturnian orbit.

NASA's Cassini spacecraft is now a nearly a year into its extended mission, called Cassini Equinox (after its initial 4-year mission ended in June, 2008). The spacecraft continues to operate in good health, returning amazing images of Saturn, its ring system and moons, and providing new information and science on a regular basis.

Astronomers are puzzled by a strange bright spot which has appeared in the clouds of Venus. The spot was first identified by an amateur astronomer on 19 July and was later confirmed by the European Space Agency's Venus Express spacecraft.

A new species of giant rat has been discovered deep in the jungle of Papua New Guinea.

Arctic temperatures are now higher than at any time in the last 2,000 years, research reveals. Changes to the Earth's orbit drove centuries of cooling, but temperatures rose fast in the last 100 years as human greenhouse gas emissions rose. Scientists took evidence from ice cores, tree rings and lake sediments.

Researchers have devised a penny-sized silicon chip that uses photons to run Shor's algorithm - a well-known quantum approach - to solve a maths problem. The algorithm computes the two numbers that multiply together to form a given figure, and has until now required laboratory-sized optical computers. This kind of factoring is the basis for a wide variety of encryption schemes.

Join Bill Nye as he delves into the Greatest Discoveries in Biology. This program explains how the early use of microscopes and Anton Van Leeuwenhock's accidental discovery set the stage for studying microorganisms. It explores 19th century research breakthroughs and covers cell division, sex cell division, and cell differentiation. Learn how the discovery of mitochondria has helped us understand reproduction, ancestral lines, and cancer; how cells convert sugars, fats, and proteins into energy in the Krebs Cycle; and how they communicate through neurotransmitters and hormones. Explore the process of photosynthesis and how the discovery of the ecosystem process bridged biology with physics, chemistry, and other fields of science that describe the environment.

Bill Nye and the Discovery Channel give you the greatest discoveries in physics. Nye explores how the universe operates and why things move and work the way they do. He also explains the second law of thermodynamics, electromagnetism, and how superconductors can help accelerate particles to near the speed of light. He illustrates Albert Einstein's theory that clocks tick slower at the speed of light and even on an airplane, and discusses how E=MC2 helped develop nuclear power, the quantum leap, the power of electromagnetic energy, the structure of an atom, and the subatomic particles known as quarks.
