Voracious black holes hide their appetite in dusty galaxies
A UK-led team of astronomers reports that they have tracked down an elusive population of black holes growing rapidly hidden behind clouds of dust.   view more (2005-08-08)

Nature can help reduce greenhouse gas, but only to a point
Plants apparently do much less than previously thought to counteract global warming, according to a paper to be published in next week's online edition of Proceedings of the National Academy of Sciences.   view more (2006-04-11)

How to Make A Black Hole Choke

Tiny 'cages' could trap carbon dioxide and help stop climate change
A natural physical process has been identified that could play a key role in secure sub-seabed storage of carbon dioxide produced by fossil-fuelled power stations.   view more (2006-03-17)

Researchers discover trees in Amazon much older than assumed, raising questions on global climate impact of region
Trees in the Amazon tropical forests are old. Really old, in fact, which comes as a surprise to a team of American and Brazilian researchers studying tree growth in the world's largest tropical region.   view more (2005-12-14)

Scientists find the reason behind black holes' light shows
A team of astronomers led by the University of Michigan may know how black holes are lighting up the Universe.   view more (2006-06-22)

Deep in the ocean, a clam that acts like a plant
How does life survive in the black depths of the ocean? At the surface, sunlight allows green plants to "fix" carbon from the air to build their bodies.   view more (2007-02-21)

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 (2005-12-07)

Road to greener chemistry paved with nano-gold, researchers report
The selective oxidation processes that are used to make compounds contained in agrochemicals, pharmaceuticals and other chemical products can be accomplished more cleanly and more efficiently with gold nanoparticle catalysts, researchers have reported in Nature magazine.   view more (2005-10-26)

Global warming could halt ocean circulation, with harmful results
Absent any climate policy, scientists have found a 70 percent chance of shutting down the thermohaline circulation in the North Atlantic Ocean over the next 200 years, with a 45 percent probability of this occurring in this century.   view more (2005-12-08)

Black hole in search of a home
The detection of a super massive black hole without a massive host galaxy is the surprising result from a large Hubble and VLT study of quasars.   view more (2005-09-15)

Sea level on the rise - in real and virtual worlds
The climate system, and in particular sea level, may be responding more quickly to rising carbon emissions than climate scientists have estimated with climate models.   view more (2007-02-05)

Hurricane Katrina: Who Was Hit? Who Will Return?
The Gulf Coast's African Americans and poorest residents were disproportionately impacted by Hurricane Katrina, according to new findings from Brown University sociologist John Logan.   view more (2006-01-26)

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)

Exercise linked to reduced breast cancer risk
Both black women and white women who regularly exercise have a decreased risk of breast cancer compared to women who do not exercise.   view more (2005-11-17)

The critical importance of mangroves to ocean life
Mangroves, the backbone of the tropical ocean coastlines, are far more important to the global ocean's biosphere than previously thought.   view more (2006-02-28)

North Sea efficient sink for carbon dioxide
The measured annual increase in the concentration of carbon dioxide (CO2) in the atmosphere is only 60 percent of the annual emissions from fossil fuels.   view more (2005-10-11)

Forest fires may lead to cooling of northern climate
Countering hypotheses that forest fires in Alaska, Canada and Siberia warm the climate, scientists at UC Irvine have discovered that cooling may occur in areas where charred trees expose more snow, which reflects sunlight into space.   view more (2006-11-17)

Increased environmental carbon levels - the good news!
Increasing carbon levels can be a good thing in some cases: scientists at the University of Durham propose that higher levels of inorganic carbon can have a positive influence on human health.   view more (2006-04-03)

Bugs expose underground carbon traffic system 10 times more important than fossil fuel burning
The flow of carbon through soil is ten times greater than the amount of carbon moved around by the burning of fossil fuel but until now how this happens was at best poorly understood.   view more (2005-10-10)

Integral looks at Earth to seek source of cosmic radiation
Cosmic space is filled with continuous, diffuse high-energy radiation. To find out how this energy is produced, the scientists behind ESA's Integral gamma-ray observatory have tried an unusual method: observing Earth from space.   view more (2006-02-13)

Reining in Carbon Dioxide Levels Imperative but Possible
Implementing a plan to keep rising carbon dioxide levels from reaching potentially dangerous levels could cost less than 1 percent of gross world product as of 2050, a cost that is well within reach of developed and developing nations alike.   view more (2006-03-09)

Greenhouse gas/temperature feedback mechanism may raise warming beyond previous estimates
A team of European scientists reports that climate change estimates for the next century may have substantially underestimated the potential magnitude of global warming.   view more (2006-05-22)

Smithsonian scientists report new carbon dioxide study
Researchers at the Smithsonian Environmental Research Center report the results of a six-year experiment in which doubling the atmospheric greenhouse gas carbon dioxide (CO2) in a scrub oak ecosystem caused a reduction in carbon storage in the soil.   view more (2007-03-13)

The inside dope
Often, things can be improved by a little 'contamination.' Steel, for example is iron with a bit of carbon mixed in. To produce materials for modern electronics, small amounts of impurities are introduced into silicon - a process called doping.   view more (2007-07-27)
