Peas and beans get by with more than a little help from friends
The relationship between leguminous plants such as peas and beans and nitrogen-fixing bacteria is even closer than previously thought, with bacteria acting like an intrinsic part of the plant, according to research published in the journal Nature today. Researchers from the University of Reading and the John Innes Centre, Norwich, have found that... view more... (2003-04-14)
North Pole's ancient past holds lessons for future global warming
Detailed information on greenhouse gasses and a subtropical heat wave at the North Pole 55 million years ago is providing information about the Earth's past as well as a portent for its future, according to reports in the June 1 issue of Nature. view more (2006-06-01)
Methane-eating microbes can use iron and manganese oxides to 'breathe'
Iron and manganese compounds, in addition to sulfate, may play an important role in converting methane to carbon dioxide and eventually carbonates in the Earth's oceans, according to a team of researchers looking at anaerobic sediments. view more (2009-07-10)
RAND study: Alternative fossil fuels have economic potential
Alternative sources of fossil fuels such as oil sands and coal-to-liquids have significant economic promise, but the environmental consequences must also be considered, according to a RAND Corporation study issued today. view more (2008-10-08)
Metal-containing compounds show promise as HIV weapon
A molecule consisting of two "cages" of metallic atoms bound to carbon has shown great promise in preliminary tests of becoming a new weapon in the anti-HIV arsenal, researchers at UT Southwestern Medical Center report. view more (2005-11-01)
Fertility experts urge clinics to consider 'natural cycle' IVF instead of routine use of ovarian stimulants
A team of UK fertility experts wants IVF clinics to consider taking advantage of a woman's natural cycle during infertility treatment instead of routinely using drugs to stimulate ovaries into producing extra eggs. A study published today (Wednesday 31 January) in Europe's leading reproductive medicine journal, Human Reproduction*, has found that... view more... (2001-01-28)
Role of Silica in Climate Cycles
New research from the University of East Anglia (UEA) has demonstrated that the compound silica was not solely responsible for changes in carbon dioxide levels during past Ice Ages. It is already known from scientific research that during past Ice Ages increased amounts of silica, a common component of wind-blown dust, were deposited in the ocean.... view more... (2001-06-21)
Detox cure for art treasure
Many museums and churches own pieces of art which were treated with toxic pesticides in the past. Between the 1940’s and 80’s, it was quite usual to protect wood against insects and microorganisms with PCP (pentachlorophenol), DDT and lindane. Though the adverse effect was only recognized later: Lindane and PCP evaporate into the air,... view more... (2002-09-09)
Why is Greenland covered in ice?
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. view more (2008-08-28)
Land won't soak up carbon indefinitely say top scientists
A paper to be published this week in the journal Nature provides a new global view of terrestrial carbon sources and sinks and warns that current sinks cannot be counted on to mop up carbon dioxide emissions indefinitely. The results have potential implications for the Kyoto Protocol negotiations where recent difficulties have included a lack of... view more... (2001-11-06)
"Live fast, die young" applies to forests, too.
Forests provide humans with economically important and often irreplaceable products and services, and affect global climate by acting as sources and sinks of heat-trapping carbon dioxide. Yet the possible responses of forests to ongoing environmental changes are poorly understood. In the most recent issue of Ecology Letters, Stephenson and van... view more... (2005-04-19)
Ma and Pa solutions to global warming
The prairies offer opportunities for capitalizing on environmentally friendly farming practices and potentially useful agricultural waste to produce jobs, economic growth, commercial opportunities, and renewable energy sources. view more (2009-04-09)
CO2 emissions could violate EPA ocean-quality standards within decades
In a commentary in the September 25, 2007, issue of the Geophysical Research Letters (GRL), a large team of scientists state that human-induced carbon dioxide (CO2) emissions will alter ocean chemistry to the point where it will violate U.S. Environmental Protection Agency Quality Criteria [1976] by mid-century if emissions are not dramatically... view more...

Carbon offset warning from international team of scientists
Leading marine scientists from across the world have issued a warning that it is too early to sell carbon offsets from ocean iron fertilisation. view more (2008-01-11)
Black carbon pollution emerges as major player in global warming
Black carbon, a form of particulate air pollution most often produced from biomass burning, cooking with solid fuels and diesel exhaust, has a warming effect in the atmosphere three to four times greater than prevailing estimates, according to scientists in an upcoming review article in the journal Nature Geoscience. view more (2008-03-24)
Some of Earth's climate troubles should face burial at sea, scientists say
Making bales with 30 percent of global crop residues - the stalks and such left after harvesting - and then sinking the bales into the deep ocean could reduce the build up of global carbon dioxide in the atmosphere by up to 15 percent a year, according to just published calculations. view more (2009-01-29)
Kentucky Geological Survey involved in global climate change research
Researchers at the Kentucky Geological Survey are studying options to reduce the amount of carbon dioxide emitted into the atmosphere. Carbon dioxide is produced by the burning of coal, gasoline, and natural gas and has been linked to global warming. view more (2005-07-15)
Milk goes 'green': Today's dairy farms use less land, feed and water
Dairy genetics, nutrition, herd management and improved animal welfare over the past 60 years have resulted in a modern milk production system that has a smaller carbon footprint than mid-20th century farming practices. view more (2009-06-11)
Incentives for carbon sequestration may not protect species
Paying rural landowners in Oregon's Willamette Basin to protect at-risk animals won't necessarily mean that their newly conserved trees and plants will absorb more carbon from the atmosphere and vice versa, a new study has found. view more (2008-07-08)
Decoded gene sequence of the diatom Thalassiosira pseudonana
For the very first time, the genetic make-up of a planktonic marine alga has been sequenced. During this process, a team of international scientists found unexpected metabolic pathways in the diatom Thalassiosira pseudonana. The results will be published in the scientific journal 'Science' this week. view more (2004-10-01)
