Check out the story I wrote for New Scientist this week on what Chinese paleontologists believe to be a 110,000 yr old human jaw bone (see photo on right).
If their claims about the fossil they found in China's southern Guangxi province prove true, it would raise some interesting questions about human origins.
Specifically it could challenge the widely held belief that modern humans are the direct descendents of Homo sapiens that migrated out of Africa around 100,000 years ago.

Obama At MIT
Check out the story I wrote and filmed for New Scientist of President Obama's address at MIT on Friday. Prior to his clean energy speech, the cynics had already written it off as a token "official" event to justify private funderaisers he would attend later in the day for Massachusetts Governor Deval Patrick and Connecticut Senator Chris Dodd.
While there may be some truth to their claims, his arrival inside MIT's Kresge Auditorium created a buzz that was nothing short of flipping the switch on Alcator C-Mod, the University's nuclear fusion reactor.
Obama faces some tough challenges, increasing skepticism, and looming deadlines as he and others look to move climate legislation through Congress. Here's hoping they succeed.

Clean Beams
Consumers may never hear of Advanced Electron Beams, but the technology the company has developed could fundamentally change the way everyday products are made in processes that could save millions of tons of carbon dioxide emissions a year.Check out the following story I wrote about the Wilmington, MA startup for Technology Review; Clean Tech's Hot New Tool
AEB replaces the heat and/or chemicals that are typically used to drive industrial reactions with electron beams.

EcoRock
I recently co-authored the following feature for New Scientist profiling some of the hottest new technologies for a cleaner, less energy intensive world.Better World: Top Tech For a Cleaner Planet
It was a fun project to work on and one that got me scouring the planet for the best in Clean-Tech.
Not every new development that I proposed made the cut, but, one in particular that deserves honorable mention is EcoRock; a new type of drywall (or sheet rock) that requires 80 percent less energy to manufacture than the conventional stuff.

Love That Dirty Water

"Raw sewage flowed from outmoded wastewater treatment plants. Toxic discharges from industrial facilities colored the river pink and orange. Fish kills, submerged cars and appliances, leaching riverbank landfills, and noxious odors were routine occurrences." -Charles River History, Charles River Watershed Association
The river Charles has come a long way since the above description
from the 1960s. The EPA now gives it a B+ in its annual Charles River Report Card, up from a D just 14 years ago.



Rachel and I spent the afternoon with friends Ben and Heather paddling a section of the river in Newton, MA, about 10 miles west of Cambridge.
The river still has room for improvement--and additional cleanup efforts are underway--but I'd give our afternoon an A+.

Dash for Green Cash
If you invested in green funds the past couple years, you likely lost your shirt--even more so than others--in the current recession according to an article in today's Boston Globe. But the smart money today, the article goes on to say, is in another type of green investing; eco-improvements on your home that will reduce your cost of living.Nowhere does this seem to be more true than in Massachusetts. I've been looking into installing solar photovoltaic panels on our condo and with the combination of state and federal tax credits and rebates, they are practically giving the stuff away.

21st Century Barnraising


For Centuries New Englanders have gathered to help their neighbors raise barns. This past Sunday my wife, Rachel, and I joined a group of our fellow Cantabrigian's in raising the energy efficiency of a neighbor's home.
For over a year the nonprofit Home Energy Efficiency Team (HEET) has organized monthly weatherization parties for buildings here in Cambridge, MA. The hosting home provides the food, local weatherization companies donate insulation, caulk, foam, and other weatherizing essentials, and volunteers provide free labor in exchange for learning how to better insulate their own home.
Each barnraising starts and ends with a "blower door" test to determine how airtight
or leaky the building is. I'd heard about blower doors before but I'd never seen one in action. It's essentially an airtight collapsible door with a large fan in the middle of it (see photo). To run a test you jam the blower door into the building's front entrance, shut all other doors and windows, and then fire up the fan which tries to pump additional air into the building. Air flow monitors connected to the fan tell you how much air is being pumped in, which in turn tells you how leaky the building is.

First Sip
Check out a couple of white headed langurs in southern China as they come down out of the trees to drink from a recently built pond at the Chongzuo EcoPark in Guangxi Province, China.

King Cobra III
A couple days after our recent run-in with a king cobra, Pan pulled the snake out of the freezer for a full dissection. He and his assistants spent a couple hours weighing, measuring, counting rings, extracting venom, and IDing organs. The cobra was likely 2-3 years old—on the cusp of breeding age—was just shy of 2 meters long, weighed 900 g (2 lbs), and had 56 dark bands from head to tail.

Like all king cobras, it likely fed exclusively on other snakes and may have limited its diet even further to a single species.
At one point Pan entertained thoughts of extracting the cobra's venom and injecting it, bit by bit, into a pig or water buffalo to cultivate antivenom. If someone was then bit on the reserve, they could simply withdraw some blood

King Cobra II
It was a warm evening and I'd stayed watching them settle into their cliff face caves a bit longer than usual. By the time I began the roughly 15 minute hike back to the reserve's headquarters, it was already quite dark.
I hadn't bothered to pack a flashlight as I knew the path fairly well and preferred to let the moonlight guide me.
Then, I started thinking about all the warnings I'd recently read about cobras. I flipped open my cell phone for what little light it offered and grabbed the first stick I could find.
After a couple minutes of fumbling around, Jintong, one of the reserve's staff, drove towards me driving an electric cart. He said he'd just run over a snake and proceeded to unfurl a very recently deceased, very large king cobra. He hit the snake on the path I was about to walk down, about 100 meters from my room.
Then, before I thought to ask for a ride, anywhere, he drove on. I froze, convinced every branch and twig I saw on the path before me was a king cobra.
Pan told me afterwards that I needed to be especially careful this time of year. The temperature here on the edge of the tropics was just starting to rise and snakes were beginning to come out in the evenings to lie in open paths warmed by the sun.
Rachel would later tell me it snowed again in Boston and that sounded pretty nice to me.

The Chicken Coop
Not far from the entrance to the Chongzuo EcoPark there is a collapsing cinder block building that once served as the living quarters for biologist Pan Wenshi and his students.I’ve seen animal enclosures in Chinese zoos that are nicer than this.
The building—an abandoned army barracks—had no running water, no electricity, no door, and a gaping hole in one wall. Pan’s bed, shown here, was a thin wicker mat laid over a row of boards. Stumps and logs were used for seats and benches. Field notes were compiled by candlelight, and when it rained, water flowed into the building.
In 2000, the county government took pity on Pan and, to honor what he'd done for surrounding villages, they spent $1 million on park improvements, including a rather architecturally inspired research facility and living space.
Until recently, the cinder block building and its Spartan furnishings served as a museum of the not-so-good-ol’ days of '96 to '00. Since my last visit, it received a long overdue conversion to its current use; a chicken coop.

Happy St. Pat's

Happy St. Patty’s Day from the PRC. I took a break from monkeying around in Chongzuo to spend a couple days in Yangshuo, China.
Yangshuo was a once gorgeous, now overrun mountain town on the Li river in southern China that has been a backpacker mecca since us laowai started descending on the country in droves in the 1990s.
The place is by no means the quiet retreat it once was, but anyplace serving the pride of St. Jame's Gate on March 17 works for me.
I spent the evening with Paul, an Englishman, and Joe, a local kid all of 10 years old.
Paul has taught English here for the last three years. He makes close to $1000 a month teaching business English in one of Yangshou’s many private schools. At this pay, he says he lives well; enough to eat out each night at the many restaurants catering to foreign tourists. He says he can’t stomach the local food, but he has a Chinese girlfriend and says the weather here beats dreary ol’ England any day.
Paul can’t stay long though as it’s “quiz”, or trivia, night at another nearby pub.
Joe is friend of Paul’s and, based on his English skills, I get the feeling this isn’t his first night hanging out at The Alley Bar. When Paul called him on his lack of green, he ran home and put on the sweater seen here. –When I ask Joe what St. Patty’s is all about, he says it’s when people wear green and drink stuff from Ireland. He says there is more to it than that, but he can’t remember the rest.
Joe first learned English from a Australian and does a wicked rendition of Crocodile Dundee's “that’s not a knife, this is a knife”.
His favorite sport is rollerblading.
“I get nice air,” he says.
Out of the blue, Joe hits me with the following riddle.
“Who is too rich?” he asks.
“Bill Gates,” I counter knowing China’s obsession with the world’s richest man.
“No, a river; it has banks on both sides.”
I go to give the kid a high five but he counters with “down low”, and then, withdrawing his hand, “too slow.”
Something tells me that of the two of them, Joe has the better gig.
