Tiny filters measuring just one-atom thick might be the next generation of technology that efficiently separates salt and impurities from water. Researchers report that they have successfully punched subnanoscale holes in graphene, the sheets of bound carbon atoms known to be one of the strongest materials on Earth.
Electricity is playing a more important role in both on-road and non-road transportation, and that's an energizing development for us all.
But it's electricity's role in powering various other transportation applications that's rarely discussed. The good news, though, is that the conversation is finally changing.
Jet engines come in all shapes and sizes. Fighter jets use sleek and narrow supersonic engines called low-bypass turbofans to generate enormous thrust. But they also guzzle plenty of gas. Passenger planes use their bigger and more efficient cousins, called high-bypass turbofans. But they are not nearly as fast.
When the body gets wounded, it naturally generates molecules known as growth factors that are critical to helping it heal. Now researchers have engineered new versions of these growth factors that can help repair wounds and bone defects in mice faster and more effectively than their own natural versions.
Government officials are constantly facing pressure to do more with less. With smaller budgets, it takes leaders with vision and energy to make strategic investments to improve how their cities function. That's where smarter cities come in.
One of my favorite anecdotes of how governments and communities can partner to make a smarter city is about using big data and analytics to combat a common urban problem: Potholes.
