The race to remove CO2 from our atmosphere is on. In an effort to draw down carbon at a meaningful scale, people are looking to the ground. The top meter of the world's soil holds over three times the amount of carbon currently in our atmosphere--and if we treat our land better, it could suck up even more. This is good news for farmers. Companies and individuals desperate to offset their emissions by purchasing carbon credits are willing to pay farmers to use sustainable agricultural practices and sequester carbon in their fields.

The recent emergence of U.S. Navy videos of UFOs--and the fact that the government is addressing them seriously--will no doubt generate larger than average buzz around "Roswell: The Final Verdict," although the title suggests something like "Final Destination 6": Will the question of intergalactic life ever really be resolved until extraterrestrials can walk comfortably among us? "Final Verdict" is hooked to the 74th anniversary of the incidents at Roswell. It's safe to expect similar celebrations next year. Meanwhile, this Discovery production is an ambitious if somewhat overheated summing-up of what happened near the New Mexico city in 1947, the stuff of both scientific speculation and folklore: Did the government cover up the crash landing of an alien spaceship, replete with otherworldly visitors? Or did the "witnesses" who claimed that it all happened construct an elaborate hoax?

The robotic ducks are designed to help children. The center is calling this a high-tech social robot. The duck uses lifelike movements and emotions to engage and help kids during their cancer care, which could sometimes last more than two and a half years. During an event on Friday at Roswell, people saw first hand how the ducks operate. After the demonstration patients participated in a scavenger hunt that would lead them to their own robotic duck.
