Gaseous State
In a lush pasture near Buenos Aires, this cow and its compatriots are digesting important information: how much methane—a greenhouse gas 20 times as potent as carbon dioxide—is released by the country’s 55 million bovines. Researchers from Argentina's National Institute of Agricultural Technology connected inflatable tanks to the cows’ first stomach, where methane is made, through a small hole between their ribs.

Turning a Sensor Toward Concussions and Kids
With grownups from the NFL to the DOD paranoid about concussions, it’s about time the research community asked, “What about kids?” Research published this month in the Journal of Sports Engineering and Technology offers a unique look into how hard kids are getting hit in hockey. The findings suggest players are suffering the biggest blows to the tops of their heads.

7.9.2008 at 07:07pm - Comment by darvargusI've played hockey since I was 4 and I think a lot of the hits to the top of the head could be because of the player keeping there head down. An inexperienced player taking the puck down the ice is going to constantly keep an eye on the puck below them. Another explanation could be from just players digging for the puck in the corners with there heads down. Even just the two center ice players waiting for the ref to drop the puck could butt heads. Some of the worst hits in hockey are due to the player not keeping there head up while in play with the puck. But I'm sure there is more then one scenario. And don't forget locker boxing!
