Volcanic activity beneath pacific ocean may indicate earth's upper mantle is more "liquefied" than previously though
University of Hawai'i at Manoa researcher Stephanie Ingle and a team of scientists from Japan and California have found evidence for the existence of partial melt in the Earth's upper mantle beneath the Pacific Ocean near Japan.
Gas escaping from ocean floor may drive global warming
Gas escaping from the ocean floor may provide some answers to understanding historical global warming cycles and provide information on current climate changes, according to a team of scientists at the University of California, Santa Barbara.
Jenolan caves 340 million years old
In a study published in the June issue of the Australian Journal of Earth Sciences, scientists from CSIRO, the University of Sydney and the Australian Museum – in cooperation with the Jenolan Caves Trust – have shown that the limestone caves, which attract thousands of tourists each year, date back more than 340 million years.
Trees appear to respond slower to climate change than previously thought
Genetic analysis of living spruce trees provides strong evidence for the presence of a tree refuge in Alaska during the height of the last glacial period (17,000 to 25,000 years ago).
At an underwater volcano, evidence of man's environmental impact
Scientists studying hydrothermal vents, those underwater geysers that are home to bizarre geological structures and unique marine species, have discovered something all too familiar: pollution.
Human tampering threatens planets's life-sustaining surface
In a report released recently, scientists call for a new systematic study of the Earth's "critical zone"--the life-sustaining outermost surface of the planet, from the vegetation canopy to groundwater and everything in between.
Predators prefer to hunt small-brained prey
Predators such as leopards and chimpanzees consistently target smaller-brained prey less capable of escape; research at the University of Liverpool has shown.
Greenland's ice loss accelerating rapidly
A new analysis of data from twin satellites has revealed that the melting of Greenland's ice sheet has increased dramatically in the past few years, with much of the loss occurring primarily along one shoreline potentially affecting weather in Western Europe.
Study shows snowfall hasn't increased over antartica in last 50 years, disputing assumptions in some climate change models
An international effort to determine the variability of recent snowfall over Antarctica shows that there has been no real increase in precipitation over the southernmost continent in the last half-century.
Deep-sea sediments could safely store man-made carbon dioxide
Deep-sea sediments could provide a virtually unlimited and permanent reservoir for carbon dioxide, the gas that has been a primary driver of global climate change in recent decades, according to a team of scientists that includes a professor from MIT.

Study breaks ice on ancient arctic thaw
A new analysis of ocean-floor sediments collected near the North Pole finds that the Arctic was extremely warm, unusually wet and ice-free the last time massive amounts of greenhouse gases were released into the Earth's atmosphere.
Satelite data reveals gravity change from sumatran earthquake
For the first time, scientists have been able to use satellite data to detect the changes in the earth's surface caused by a massive earthquake.
Diamond technology to revolutionize mobile communications
The U. S. Department of Energy's Argonne National Laboratory has teamed with industrial and academic partners under a DARPA Phase II research and development program to develop a new technology based on Ultrananocrystalline Diamond™
Small-scale logging leads to clear-cutting in brazilian amazon
A team of scientists, led by Greg Asner of the Carnegie Institution's Department of Global Ecology, has discovered an important indicator of rain forest vulnerability to clear-cutting in Brazil.
Three continents collide to create australia
A PhD student in the University of Adelaide's School of Earth and Environmental Sciences has found evidence of a collision between northern and central Australia 1.64 billion years ago.
More fires, droughts and floods predicted
As temperatures rise with global warming, an increased risk of forest fires, droughts and flooding is predicted for the next 200 years by climate scientists from the University of Bristol, UK.
Clock in the rock
The mass extinction of dinosaurs occurred about 66 million years ago, at the end of the Cretaceous Period (K) and the beginning of the Tertiary Period, known as the K-T boundary. A massive asteroid slammed into what is now the Gulf of Mexico about that time.
Climate change was major factor in erosion of alps 6 million years ago
The Alps, the iconic rugged mountains that cover parts of seven European nations, might have reached their zenith millions of years ago, some scientists believe, and now are a mere shadow of their former selves. New research offers an explanation.
Ocean noise has increased considerably since 1960s
When Hongrui Jiang looked into a fly's eye, he saw a way to make a tiny lens so "smart" that it can adapt its focal length from minus infinity to plus infinity — without external control.
Study reveals causes behind freshwater increase in north atlantic and artic oceans
A new analysis of 50 years of changes in freshwater inputs to the Arctic and North Atlantic oceans may shed light on what's behind the recently observed increase in freshwater in the North Atlantic. University of Texas at Austin marine scientist Dr. Jim McClelland and his colleagues report their findings in the Aug. 25 issue of the journal Science.
