7:00 PM | Flying Blind
By Bruce Stutz It was a late-afternoon departure from JFK to LAX that would have us flying into the sunset. As it turned out, I had an aisle seat. But I knew I could still lean over enough to catch some sight of the expanses below. And I imagined that most of the people on the plane—families and tourists coming and going for the holidays—would be looking out to enjoy the scenes as well. But on takeoff all the shades went down, plunging the cabin […]

2:14 PM | Bad Bugs Remake America, Swim at Your Own Risk, Koi Pond Gone Wild
By Jason Bittel Just when you thought it was safe to go in the water: The Environmental Protection Agency has released a draft plan that would lower the levels of acceptable waterway contamination that could occur without providing warnings for swimmers. State officials from the Great Lakes to the country's coasts are coming out against the new requirements, saying the warnings will scare beachgoers and hurt tourism revenue. It’s the classic […]

2:05 AM | How much surface area can you fit in a space the size of an ice cube? Several football fields in a new battery cathode!
If any of us ever hope to complete the romantic cross-country trip across the US by electric car, the answer lies in better battery technology.  Current batteries just can’t store enough energy to last trips without frequent stops to recharging stations. … Continue reading →

2:16 PM | Playing Chicken with Rhinos, NY to Fracking: Get Outta Town, Measuring Climate Change from SPACE!
By Jason Bittel Republican to Republican: Fans of a smaller government may want to heed the advice of the former U.S. Treasury Secretary under George W. Bush, Henry Paulson. According to Paulson, refusing to take immediate action against climate change will only ensure “that the government will be playing a bigger role,” because an increased number of natural disasters will necessitate more oversight. Paulson also says he thinks many of his […]

7:03 PM | Teach a Country to Fish...
By Ben Goldfarb This time last year, I found myself standing on the rocky shores of Alaska’s Bristol Bay, home to a world-renowned salmon fishery that brings in $1.5 billion annually. Lunchtime had just rolled around in the remote fishing camp I had come to visit—and when you’re sharing a body of water with 40 million sockeye, you don’t order a ham sandwich. One of my hosts, a bearded fisherman named Zach, strung a gillnet into the […]

5:49 PM | The Power of Truth
By Emily Cousins Soon after Joel Reynolds joined NRDC (which publishes OnEarth) in 1990, he took on a case for the Mothers of East Los Angeles, a group of largely low-income Latino women trying to prevent construction of a toxic waste incinerator in their community. Local officials had approved the project without conducting a proper environmental review, so Reynolds took them to court. At hearings, he says, his clients would “file quietly into the […]

By Jason Bittel Chickpeas, anyone?: Eight months have passed since the Foster Farms salmonella outbreak, and people are still getting sick (more than 600 in all). Even so, the company won't volunteer a recall of its meat, and the U.S. Department of Agriculture doesn’t seem to think it has the legal authority to force it. Good thing for you finger-lickn’ chicken lovers out there: A new bill—the Pathogens Reduction and Testing Reform […]

You might have noticed a lot of emails from Canadian companies recently, asking you to confirm that you wish to receive emails from them. This is because a key part of the 2010 anti-spam law comes into effect tomorrow. We haven't sent you anything, becase we have always complied with the spirit of the law. What is spam? We all know what spam is, and the Canadian government's definition is plain: commercial electronic messages [received] without the recipient's consent And here's a definition […]
