  • After midnight on Sept. 12, 1964, Romaine Tenney, a hardscrabble farmer in Ascutney, Vt, let his cows out of the barn to wander freely. Then he set his barn on fire. Then he went into his house and set it on fire. While the flames roared up around him, the autopsy suggests, he shot himself. The interstate highway was coming.

    Tenney, 64, a bachelor and lifelong resident of Ascutney, didn’t own a car. Interstate 91 was planned to come straight through his property, and so his house and barn had been condemned under eminent domain. He had fought this taking and lost. Rather than accept a settlement check and move, he died where he had long lived.  [...]

    “Some of the most haunting images are those of doomed homes,” Bierman and his graduate student, Analeisha Vang, write. “Often families were occupying the homes while the photographs were taken, and the things of daily life — family photos on the wall, toys on the floor, and fastidiously made beds — makes the viewer feel like a voyeur.”

  • ROCKLAND, N.Y.-- Radioactive leftovers from Eisenhower-era bomb tests could help save the African elephant from extinction, thanks to a team of scientists.

    The team led by a researcher now at Columbia University's Lamont-Doherty Earth Observatory inRockland has developed a forensic technique that it says will cut down on elephant poaching and the illegal ivory trade. The method determines a tusk's age, revealing if it was acquired before or after a 1989 ban on trade in African elephant ivory.

    The study was published this month in theProceedings of the National Academy of Sciences.

    "A lot of the trade regulations depend on the year or the age of that tissue," said Kevin Uno, a paleoecologist at Lamont. "So we can date a tusk now and say, well, this has been traded illegally because of the age of the ivory or the date at which the elephant died."

  • I had heard stories about the 48 hour party since I started at Ohio State last summer. I’ll admit that the idea of a 48 hour party was intriguing, and perhaps a bit painful. The talk of 2-5 AM shifts had the sound of cruel and unusual punishment. The overnight shifts never materialized, however. The final plan involved manning the infrared camera from 1 PM to 10 PM, with an overnight break before resuming at 6 AM and continuing to 1 PM. Photos of one of the glaciers behind Cuchillacocha were to be taken every 15 minutes. Once every 30 minutes qualified as acceptable but not ideal. Once every hour would be considered “scandalous”. The photos would become part of a large collection of atmospheric and hydrologic data taken in the Cuchillacocha basin over a 24 hour period.

  • Jeff Mow, a 25-year veteran of the National Park Service (NPS), has been named superintendent of Glacier National Park in northwestern Montana. Mow, who is now superintendent of Kenai Fjords National Park in Alaska, will begin his assignment at Glacier on Aug. 25.

    Mow, who has led NPS management and stewardship at Kenai Fjords since November 2004, is eager to return to Glacier and Montana. "My first visit to the park was in 1988 as a wild land firefighter on the Red Bench Fire near Polebridge," he recalled. "Twenty-five years later, it is such an honor and privilege to return as superintendent and a newest member of Glacier's outstanding management team. I can't wait to join with the park staff and partners as we meet numerous challenges and opportunities facing the park in the next few years."

  • Nasa is finally thinking about getting its Curiosity rover on the road and heading towards the big mountain at its exploration site in Mars' Gale Crater.

    The robot has spent the past six months in a small depression, drilling its rocks and analysing their composition.

    But even as the labs do their analysis, Curiosity has started moving towards a rock feature it saw briefly on the way into Yellowknife Bay.

    Known as Point Lake, this outcrop has an unusual holey appearance - like Swiss cheese. Scientists are unsure as to whether it is volcanic or sedimentary in character.

    "One idea is that it could be a lava flow and those are gas vesicles, and you often see in volcanic rocks on Earth that those kinds of holes are sometimes filled in by secondary minerals. That's one possibility," said Dr Joy Crisp, the deputy project scientist for Curiosity.

    Joy Also Explained The Presence Of The "Mars Rat"

  • Windmilling his kayak paddle into the pushy breeze, Luc Mehl, 34, pulls onto the sandbar at the mouth of Mexico’s Rio Antigua and squints at the novelty of a flat, seascape horizon in the hazy afternoon glare. Two days of sleepless dysentery have drained Mehl’s prodigious vigor and his hands are blanched and clammy as we high-five. Still, he’s grinning with accomplishment in the salt air.

    Eleven days earlier we’d set out pedaling bikes strapped with mountaineering and whitewater paddling gear in Cholula de Rivadavia, a ciudad 60 miles east of Mexico City. Without ever having visited Mexico before, Mehl composed a 230-mile bike/hike/packraft triathlon first to Pico de Orizaba (18,491 feet) and then descending through rain forest hamlets to a whitewater river. Now at sea level, we found the end of Mehl’s line.

  • Dr. Joseph Colgan '98, a research geologist with the USGS, was named one of President Obama's recipients for the Presidential Early Career Award for Scientists and Engineers, including a reception at the White House. This is the highest honor bestowed by the United States government on science and engineering professionals in the early stages of their independent research careers. Joe was recognized for his work in the Basin and Range.

    Congratulations Joe!

  • Did you know that Earth's solid exterior can move around over its core, causing the planet's poles to wander back and forth? Adam Maloof, associate professor of geosciences at Princeton University, discusses the consequences of these shifts, and what may be causing them.  [...]

    A new study published in the journal Nature, though, may help explain what causes this colossal slip and slide, and that's what we're talking about next.  [...]

    LICHTMAN: OK. So what are we talking about?

    MALOOF: We're talking about the rest of the Earth: the crust, the rest of the lithosphere and the entire mantle sliding over the outer core. So the way you imagine this is the core of the Earth, the outer part, is actually fluid iron, and it has about the viscosity of water. So we're literally sliding, you know, 2,700 kilometers of mantle over this so that, as perceived from space, what you'd see is the spin axis is staying the same, but all the continents are moving together to a new location.
