Coral reefs found growing in cold, deep ocean
Imagine descending in a submarine to the ice-cold, ink-black depths of the ocean, 800 metres under the surface of the Atlantic. view more (2008-11-05)
Studies of ancient climates suggest Earth is now on a fast track to global warming
Human activities are releasing greenhouse gases more than 30 times faster than the rate of emissions that triggered a period of extreme global warming in the Earth's past, according to an expert on ancient climates. view more (2006-02-17)
New findings show a slow recovery from extreme global warming episode 55 million years ago
Most of the excess carbon dioxide pouring into the atmosphere from the burning of fossil fuels will ultimately be absorbed by the oceans, but it will take about 100,000 years. That is how long it took for ocean chemistry to recover from a massive input of carbon dioxide 55 million years ago, according to a study published this week in the journal... view more...

The Milky Way shaped life on Earth
Frenzied star-making in the Milky Way Galaxy starting about 2400 million years ago had extraordinary effects on life on Earth. view more (2006-11-15)
Report Warns about Carbon Dioxide Threats to Marine Life
Worldwide emissions of carbon dioxide from fossil fuel burning are dramatically altering ocean chemistry and threatening marine organisms, including corals, that secrete skeletal structures and support oceanic biodiversity. view more (2006-07-06)
Oceans may soon be more corrosive than when the dinosaurs died
Increased carbon dioxide emissions are rapidly making the world's oceans more acidic and, if unabated, could cause a mass extinction of marine life similar to one that occurred 65 million years ago when the dinosaurs disappeared. view more (2006-02-21)
Origins of Life
The origin of life lies in unique ocean reefs, and scientists from the University of Miami's Rosenstiel School of Marine & Atmospheric Science have developed an approach to help investigate them better. view more (2006-11-20)
Ocean acidification threatens cold-water coral ecosystems
Corals don't only occur in warm, sun-drenched, tropical seas; some species are found at depths of three miles or more in cold, dark waters throughout the world's oceans. view more (2006-04-03)
Modeling of long-term fossil fuel consumption shows 14.5 degree hike in temperature
If humans continue to use fossil fuels in a business as usual manner for the next several centuries, the polar ice caps will be depleted, ocean sea levels will rise by seven meters and median air temperatures will soar 14.5 degrees warmer than current day. view more (2005-11-02)
Virtual colonoscopy reveals diseases outside the colon, as well
Computed tomographic (CT) colonography, known as virtual colonoscopy, can be used to diagnose significant medical problems in organs outside the colon, according to a new study conducted at the San Francisco VA Medical Center (SFVAMC). view more (2005-07-27)
Ohio University Researchers Discover Evolutionary Oddity in Flamingos
With their spindly legs, long necks and bright plumage, flamingos are a curiosity of nature. Now a new discovery by a team of Ohio University researchers reveals an anatomical oddity that helps flamingos eat: erectile tissue. view more (2006-10-31)

Phytoplankton bounce back from abrupt climate change
Marine sediment cores contain calcareous plankton - single-celled organisms with a coating or shell of calcium carbonate - as fossils. These tiny photosynthesizing plants float in the ocean and move with the currents. view more (2006-02-17)
Watching rocks grow: Theory explains landscape of geothermal springs
Scientists at the University of Illinois at Urbana-Champaign have successfully modeled the spectacular landscapes seen at geothermal hot springs. view more (2006-07-06)
Regardless of global warming, rising CO2 levels threaten marine life
Like a piece of chalk dissolving in vinegar, marine life with hard shells is in danger of being dissolved by increasing acidity in the oceans. view more (2007-03-09)
Relic of life in that Martian meteorite? A fresh look
Since the mid-1990s a great debate has raged over whether organic compounds and tiny globules of carbonate minerals imbedded in the Martian meteorite Allan Hills 84001 were processed by living creatures from the Red Planet. view more (2006-03-23)
UAF geologist studies Chicxulub impact crater
About 65 million years ago, a massive disruption led to worldwide extinction of dinosaurs. The impact of a giant asteroid created massive tsunamis and spewed forth a global cloud of carbon gases that altered Earth's atmosphere and blocked the light for weeks, possibly years. In recent years, that impact event has been linked to a 112-mile-wide... view more... (2007-01-19)
Helping Out a High-Temperature Superconductor
Researchers at the U.S. Department of Energy's Brookhaven National Laboratory have discovered a way to significantly increase the amount of electric current carried by a high-temperature superconductor, a material that conducts electricity with no resistance. view more (2005-09-15)
Engineered eggshells to help make hydrogen fuel
Engineers at Ohio State University have found a way to turn discarded chicken eggshells into an alternative energy resource. The patented process uses eggshells to soak up carbon dioxide from a reaction that produces hydrogen fuel. It also includes a unique method for peeling the collagen-containing membrane from the inside of the shells, so that... view more... (2007-09-27)
New wrinkle in the mystery of high-Tc superconductors
In the twenty years since the discovery of high-temperature (Tc) superconductors, scientists have been trying to understand the mechanism by which electrons pair up and move coherently to carry electrical current with no resistance. view more (2006-03-17)
