The geysers of Yellowstone National Park owe their eistence to the "Yellowstone hotspot"--a region of molten rock buried deep beneath Yellowstone, geologists have found. But how hot is this "hotspot," and what's causing it?

Tropical Storm Gustav gathered punch as it churned toward Cuba and the United States Wednesday after lashing Haiti and the Dominican Republic with hurricane force winds and rain that killed 16 people.

Scientists on Wednesday said they had discovered deep-sea viruses to be an unexpectedly potent driver of the so-called carbon cycle that sustains oceanic life and helps dampen global warming.

There have been many reports in the media about the effects of global warming on the Greenland ice-sheet, but there is still great uncertainty as to why there is an ice-sheet there at all.

(PhysOrg.com) -- By analyzing light from small, faint galaxies that orbit the Milky Way, UC Irvine scientists believe they have discovered the minimum mass for galaxies in the universe - 10 million times the mass of the sun.

New Hubble and Chandra observations of the cluster known as MACSJ0025.4-1222 indicate that a titanic collision has separated dark from ordinary matter. This provides independent confirmation of a similar effect detected previously in a target dubbed the Bullet Cluster, showing that the Bullet Cluster is not an anomalous case.

The Democratic Party is using beer-based biofuel and a recycling brigade guarding trash cans to help ease the environmental impact of its convention in Denver this week.

(AP) -- Arctic Ocean sea ice has melted to the second lowest minimum since satellite observations began, according to scientists at the National Snow and Ice Data Center. Sea ice melt recorded on Monday exceeded the low recorded in 2005, which had held second place.

(PhysOrg.com) -- NASA's newest space telescope is giving scientists their best look yet at the highest-energy gamma ray bursts generated by violent events in space. For Toby Burnett, a University of Washington physics professor, it's a welcome payoff for 13 long years of work.

(PhysOrg.com) -- Conservation zones are in the wrong place to protect vulnerable coral reefs from the effects of global warming, an international team of scientists warned today.

(PhysOrg.com) -- The next sample of Martian soil being grabbed for analysis is coming from a trench about three times deeper than any other trench NASA's Phoenix Mars Lander has dug.

A recent study forecasts that increased climatic variability poses serious consequence for both the biodiversity and ecosystem function of high-elevation lakes.

Hurricane Gustav slammed into Haiti Tuesday, lashing the desperately poor Caribbean nation with powerful winds and heavy rain, just days behind deadly Tropical Storm Fay.

Oregon State University scientists have completed a new analysis of an earthquake fault line that extends some 200 miles off the southern and central Oregon coast that they say is more active than the San Andreas Fault in California.
