Historic levels of particles in the atmosphere released from pre-industrial era fires, and their cooling effect on the planet, may have been significantly underestimated according to a new study.

Investigators have discovered that arsenic in combination with an existing leukemia drug work together to target a master cancer regulator. The team, led by researchers at the Cancer Center at Beth Israel Deaconess Medical Center (BIDMC), is hopeful that the discovery could lead to new treatment strategies for diverse types of cancer. Their findings were published today online in Nature Communications. 

Why does the egg size of house sparrows vary so much? Isn’t it always an advantage to be big?

Perhaps not surprisingly, baby sparrows that hatch from large eggs are consistently bigger their small egg counterparts. They can store up more reserves if food becomes scarce. So you would think that it’s always a good idea to lay big eggs because your offspring would seem to have a greater chance of survival.

Flooding caused by rain falling on snowpack could more than double by the end of this century in some areas of the western U.S. and Canada due to climate change, according to new research from CU Boulder and the National Center for Atmospheric Research (NCAR).

One by one, Dr. Chris Opio and Chandehl Morgan carefully remove trees from one-gallon buckets.

Researchers from NOAA, U.S. Geological Survey and their partners have completed the first high-resolution, comprehensive mapping of one of the fastest moving underwater tectonic faults in the world, located in southeastern Alaska.

Hurricane Hector maintained its major hurricane status on Aug. 8 as NASA's Aqua satellite passed overhead. Infrared data from NASA's Aqua satellite provided forecasters with cloud top temperatures in Hector so they could pinpoint the strongest part of the storm.

Injecting particles into the atmosphere to cool the planet and counter the warming effects of climate change would do nothing to offset the crop damage from rising global temperatures, according to a new analysis by University of California, Berkeley, researchers.

A futuristic experiment simulating warmer environmental conditions has shown that peatland vegetation responds to higher temperatures with an earlier and longer growth period. A study published in Nature revealed that turning up the heat accelerates spring greening in mature trees, shrubs and mosses and delays fall color change.

NASA's Aqua satellite passed over the Central Atlantic Ocean and looked at cloud top temperatures in Debby, revealing the storm had transitioned from subtropical to tropical.
