Alexander van Geen, a geochemist at Columbia University in New York, US, has been focusing his efforts on testing wells that are already in use. In 2000, his team measured the levels of arsenic in 5000 wells in Bangladesh and, armed with the GPS location of each well, looked at the spatial variability. 'What was striking is that the distribution was very heterogeneous,' he says. 'We calculated that, over our area, 50% of the people had wells with water that they should not be drinking from. However, 90% of these same households lived within 100m of a safe well.'
Researchers just returned from a month in backcountry New Zealand trying to determine whether dust from New Zealand may have contributed to the last ice age.
Lamont oceanographer Arnold Gordon lists the difficulties in finding the plane in this part of the Indian Ocean.
The landslide on Alaska's Mount La Perouse, discovered by a team of Lamont scientists, is thought to be the largest known natural landslide on Earth since 2010.
“This discrepancy between theory and observation, a major puzzle for four decades, has finally been resolved,” said Sean Solomon, principal investigator on the NASA mission and director of the Lamont-Doherty Earth Observatory at Columbia University. “It is wonderfully affirming to see that our theoretical understanding is at last matched by geological evidence.”
Lamont's Tim Creyts explains what glaciers are, how they move and sculpt the landscape, and how climate change is affecting glaciers around the world.

The invention of a car that gets 100,000 miles to the gallon would shrink global car emissions and help to slow the rate of global warming, says Lamont-Doherty climate scientist Peter deMenocal.
Lamont-Doherty seismologists in 2011 linked a series of earthquakes near Youngstown, Ohio, to underground wastewater injection wells.
New research suggests that Genghis Khan, one of the greatest conquerors in all of history, may have been given an advantage by Mother Nature, says a new study led by Lamont's Neil Pederson.
The explosion generated weak signals that were recorded at seismic stations in NYC monitored by Lamont-Doherty Earth Observatory.

Lamont-Doherty seismologist Won-Young Kim discusses a string of recent earthquakes near an oil and gas drilling site in Lowellville, Ohio.
New maps released by the GEOTRACES program co-led by Lamont's Robert Anderson show that the lead now banned in gasoline is widely found in the oceans.
Warming temperatures and rainfall led to the rise of Genghis Khan and his Mongol empire, says a new study led by Lamont's Neil Pederson.
How did the Mongols build an empire? A new study in PNAS led by Lamont's Neil Pederson suggests that a run of bountiful rains gave them the resources to invade and conquer.
Lamont seismologist Klaus Jacob comments on a U.S Government Accountability Office report confirming the vulnerability of U.S. energy infrastructure to a changing climate.
The landing of missing Malaysia Airlines Flight 370 in shallow water would aid recovery efforts, says Lamont-Doherty oceanographer Arnold Gordon.
NOAA scientist Martin Hoerling echoes Lamont climate scientist Richard Seager's view that California's ongoing drought is due to natural climate variation and not global warming.
New pictures and information about the Alaska landslide discovered by Lamont's Colin Stark, Goran Ekstrom and Clement Hibert.
