What happens first in Vegas: bike lanes or bikes?

Las Vegas is a good place to test the theory of induced demand: In a city hostile to cyclists, will better bike infrastructure convert more drivers into riders?

When soil isn’t green (it’s people)

Gardeners should take a good hard look at what's in our urban soil. But does that mean rural soil should get off easy?

Roundup weed killer is showing up in air and water

Hey, what's even better than weed killer being sprayed on crops you eventually eat? How about if it then ends up in air, water, and even rain? AWESOME. I SEE NO POSSIBLE DOWN SIDE TO THIS PLAN.

Seriously, this is pretty alarming news: Researchers from the U.S. Geological Survey have detected the active ingredient of Roundup, a chemical called glyphosate, in waterways, air, and rain. On the one hand: Those raindrops have no weeds in them, by God. On the other hand: Everything else about this.

They take a lot of energy, because they do all the things, but more than that they take a lot of cooling; keeping data centers from overheating requires up to half […]

Gigantic flywheels recover, recycle subway trains' energy

If subway stations could harvest the energy of incoming trains as they hit their brakes, they could re-use that same energy to launch the same train as it leaves the station. That's the idea behind Vycon flywheels, which are gigantic spinning wheels that act as temporary energy storage mechanisms.

Looks like we might get a do-over Earth after all

A research team at Chile's La Silla Observatory has found a new crop of 50 exoplanets, at least one of which is in the "habitable zone" (i.e. an Earthlike distance from the sun). HD 85512 b is rocky instead of gaseous, big but not too big, and preliminary observations suggest an average surface temperature of a balmy 77 degrees F -- all of which make it a good candidate to be Earth Mark II. Phew, just in time! This one's almost worn out!
