Grand Canyon, could you please show us your birth certificate? A new theory that parts of the Grand Canyon were carved as far back as dinosaur days has geologists picking sides on a controversy. New research contends that the western end of the canyon might be up to 70 million years old, carved by an ancient river that flowed in the opposite direction of today's Colorado River. Conventional theories about the canyon had its aged pegged at 5 to 6 million years old.

So what do you think?

How's this for a mash-up of Halloween and science? A newly created artificial bat cave in Tennessee is helping reduce the spread of disease that's killed 5 million bats. It even has air conditioning!!!

Meanwhile, back on Mars, the Curiosity rover has sent back some very cool close-up photos of an intriguing rock outcrop it found on the Red Planet's surface. My first impression looking at the image (which is comprised of several shots stitched together by graphic designer Ed Truthan) is that it looks like it's made up made up of cobbles, and pebbles and sand - the same kind of deposit you find here on Earth left by an old river channel.

A full-sized click-to-make-it- bigger version of the image is available on the Wired website.

The way technology usually works, things get smaller and faster to be more efficient. That's not the case with wind turbines. Read this interesting piece on how new innovations are making wind turbines taller (reaching up into the sky the length of a football field), the blades are getting longer and are moving slower. All of this is actually generating more electricity.

The headlines seem to be especially crazy these days, but this one really jumped out at me. So does the Minnesota Zoo have the coolest moose in the country, or what?

Just to follow-up on the recent posts, the Minnesota State Fair has decided to allow the public access to the swine barn this year, even in light of heightened risk of H3N2v flu. You can read all the details about the decision here.

Check out some amazing footage of mud and debris flowing from nearby mountains during a heavy rainfall in the village of Virgen, Austria. What's cool is that the flows come in pulses, which I guess is typical of this kind of thing there.

Not that you probably couldn't guess this, but it's now official. July of 2012 was the hottest month ever in the United States, topping the aggregate temperature record for a month set during the middle of the Dust Bowl years in 1936. You can read all the steamy data on this record here.

Bolting for gold: Jamaica's Usain Bolt (yellow jersey) became a two-time 100-meter gold medalist in the Olympics Sunday. How much has the winning 100 meter time decreased over the 116-year history of the Olympics?

Each Olympics, one of the marquee moments is the men's 100-meter dash finals. Who will be crowned the fastest man on the planet? Did you watch Usain Bolt's gold-medal run Sunday night? Check this New York Times interactive display that "charts" a race between all Olympic 100-meter medalists over the past 116 years. How much has one of the ultimate human performance measures improved over that time? What factors have made humans get so much faster over that time?
