Whether you're tackling mountain trails or just trying to get through Manhattan's Chinatown, rough terrain can put your bike's tubes at serious risk. It's not usually an option to hop off and adjust your tire pressure, but a company called Adaptrac has a system that mounts a toggle right on your handlebars and allows you to raise or lower your pressure even while riding.

When it comes to the physics of climate change, no one year is more important than any other. But for the politics of climate, 2012 will be a big one, less about what officials may do than what they may block or undo.
There are plenty of reasons to disagree with President Obama and Bill Gates, but there's no denying that both men are profoundly smart. And when they start agreeing on something, lesser minds like us should probably take notice. In his recent TED talk, the former Microsoft chairman sided with the president in identifying nuclear power as the only economically viable option for providing a growing world with power, while stopping the CO2 emissions that cause global warming.
With the conference in Copenhagen swiftly approaching, and the Senate analog to the Waxman-Markey "American Clean Energy and Security Act" struggling towards the floor, little doubt remains that fossil fuel-burning power plants will soon face either fines for, or mandatory reduction of, carbon emissions. Luckily, a team at MIT has devised a power plant set up that generates power from fossil fuels, but does so with almost none of the carbon emissions.
Scientists have repeatedly touted the possibility of turning algae into biofuels. Now a Florida-based company called Algenol is working with Dow Labs in Texas to convert carbon dioxide produced by algae farms into ethanol, which will then be used to make plastics. Even better, the oxygen byproduct left over from the conversion can be used to produce cleaner, more efficient coal power.
An excess of CO2 is having an unforeseen effect on shelled undersea creatures

Global warming is far and away the symptom at the top of the list of indicators that our planet is overloaded with carbon dioxide. Another important, but less considered consequence of the excess CO2 is the effect it has on the world's oceans. The oceans are a natural carbon dioxide sponge, responsible for maintaining the balance of CO2 in the atmosphere by absorbing a measure of the gas in its water. Currently, it is estimated that the ocean is uptaking nearly one-third of all human-produced CO2, which is slowly lowering its overall pH. Put simply: the oceans are becoming acidic.
