Would you want to live in a world that looks like a Pandora knockoff, or blares like the wall decorations of a stoner crash pad? What if you couldn’t turn it off?

Such were the questions raised when a Kickstarter campaign launched to “create real glowing plants in a do-it-yourself biolab in California.” At first, observers merely wondered if the technology could work. But as time passed, their questions moved on to more troubling concerns regarding the unregulated spreading of genetically modified seeds…

Could glow-in-the-dark plants replace streetlights?

For green energy, there’s no place like loam

Petroleum use is rife with environmental and security issues, and first-generation biofuels fall well short of carbon neutrality. Moreover, as global food crops literally lose ground to biofuel production, mounting scarcity is driving up food prices, increasing global hunger and political instability.

But what if we could have our rice and burn it, too? What if we could derive energy from crops without killing them, or generate power using plants and land not needed for food, all through the power of microbes?

Putting the green in nanomachines

We tend to think of nanotechnology as the stuff of the future, but it’s already here, in hundreds of consumer products and industrial applications. As progress in this minuscule world has accelerated, concern for the environment and for public health has led to a call for green nanotechnology—approaches that accentuate the positive and eliminate the negative. In this article, we’ll take a tour of how these many approaches are playing out.

How is green nanotechnology being used?

The M.A.D. world of Alfred Nobel

Leave a comment

Alfred Nobel and several recipients of his namesake Peace Prize alike contributed to warfare and violence in numerous ways—a fact that some find ironic. Yet, Nobel lived at a time when scientists didn’t consider themselves responsible for how others used their inventions, and he held a view of destructive-weaponry-as-deterrent that presaged the Cold War philosophy of Mutually Assured Destruction, so perhaps there was a method to his M.A.D.-ness. As for the others I discuss in my article below, only history can judge.

Why is the Nobel Peace Prize kind of ironic?

Phoenix and Portland plan for potable problems

Phoenix, Ariz., is a sprawling desert city with twice the population of Portland, Ore., and one-fifth its annual rainfall. The Valley of the Sun irrigates its golf courses with water channeled from the Salt, Verde and Colorado Rivers, while the City of Roses guzzles winter rains and stores the remainder in the reservoirs of the Bull Run Watershed.

What could these two cities possibly have in common? Simple. They both face seasonal water shortages if projections of population growth and climate change hold true.
