Making Tires “Green”

Cars may soon be equipped with the world’s first “green” tires made from plant byproducts rather than petroleum or rubber trees—the traditional raw materials used to make tires. This new type of tire would be produced by microbes that convert sugar into rubber.


Moving Satellites with Ions

Dawn, a spacecraft that will explore two large asteroids, is powered by an innovative ion propulsion engine. This type of engine is so efficient that it can thrust off and on for five years, gradually adding velocity.

Atomic Elements Get a Weight Change

Ten atomic elements are undergoing a change that will be listed on new periodic tables. Their atomic weights will be posted as intervals instead of a single value, a change that will be critical to calculations in scientific research and for industrial applications.

Rare Earths: Valuable and in Short Supply

Inside your cell phone, laptop, and iPod is a small bit of what chemists call “rare earth metals.” They are not particularly rare, but the places where they occur have many people worried about a continual supply to keep our electronics running.

Try, Try Again

What if you tried a chemical experiment and it failed? Would you do it over? What if it failed 1,200 times? Most of us would give up way before that! But Tobias Ritter, a chemistry professor and researcher at Harvard University, Cambridge, Mass., kept experimenting.

Superfast Computers

Do you wish your laptop would start faster? That you could switch it on and, one second later, it would be ready? Or that you could record and watch entire movies on your mobile phone? These scenarios may be possible in the near future thanks to a new type of memory chip called phase-change memory.
