Car batteries don’t last forever. Generally, they need to be replaced every five to six years, sometimes sooner, depending how worn they are. But engineers working to develop batteries for Tesla claim to have created one that can outlast a typical vehicle’s power source by over a decade.
Researchers at Dalhousie University in Canada tested a new lithium-ion cell battery that could last for roughly 20 years, or one million miles, according to ...read more

As cement hardens through a process called hydration, the molecules within the mixture develop millions of microscopic crystals, like those seen in this screenshot from the NASA video below. These interlocking crystals help the cement molecules bind with each other, as well as other concrete ingredients like gravel, sand, and small rocks. (Credit: NASA ScienceCasts)
Concrete, in one form or another, has been a staple of human construction for some 5,000 years. Now, researchers have finally b ...read more
