Picture a dinosaur. Huge, menacing creatures, they ruled the Earth for nearly 200 million years, striking fear with every ground-shaking stride. Yet these great beasts were no match for a 6-mile wide meteor that struck near Mexico 65 million years ago

What Caused Earth to Hold Its Last Breath?
Posted on February 18, 2010 at 10:40:35 pm
When Earth was young, it exhaled the atmosphere. During a period of intense volcanic activity, lava carried light elements from the planet's molten interior and released them into the sky. However, some light elements got trapped inside the planet.

Forests Are Growing Faster

A new study in the Proceedings of the National Academy of Sciences has found evidence that forests in the Eastern United States are growing faster than they have in the past 225 years. The study offers a rare look at how an ecosystem is responding to clim

White Roofs May Successfully Cool Cities
Posted on February 02, 2010 at 08:26:54 am
Painting the roofs of buildings white has the potential to significantly cool cities and mitigate some impacts of global warming, a new study indicates.

Posted on February 01, 2010 at 08:47:28 am
The sea level in Israel has been rising and falling over the past 2,500 years, with a one-meter difference between the highest and lowest levels, most of the time below the present-day level.

Maximum Height of Extreme Waves Up Dramatically in Pacific Northwest
Posted on January 29, 2010 at 08:53:54 am
A major increase in maximum ocean wave heights off the Pacific Northwest in recent decades has forced scientists to re-evaluate how high a "100-year event" might be

Cave Reveals Southwest's Abrupt Climate Swings During Ice Age
Posted on January 29, 2010 at 08:47:39 am
Ice Age climate records from an Arizona stalagmite link the Southwest's winter precipitation to temperatures in the North Atlantic, according to new research.

Novel Way in Which Animals Sense Earth's Magnetic Field
Posted on January 28, 2010 at 09:38:20 am
Neurobiologists at the University of Massachusetts Medical School (UMMS) have linked two related photoreceptor proteins found in butterflies to animal navigation using the Earth's magnetic field.

Venus Flytrap for Nuclear Waste?
Posted on January 28, 2010 at 09:33:44 am
Not every object is food to a Venus flytrap. Like the carnivorous plant, a new material developed at Northwestern University permanently traps only its desired prey, the radioactive ion cesium, and not other harmless ions like sodium.

Global Warming 'Feedback' Less Than Thought?
Posted on January 28, 2010 at 09:27:26 am
A new estimate of the feedback between temperature and atmospheric carbon dioxide (CO2) concentration has been derived from a comprehensive comparison of temperature and CO2 records spanning the past millennium.
