Arctic marine organisms capture CO2
Arctic marine organisms act as a reservoir for CO2, according to research published in the international journal Geophysical Research Letters.
Obstacles to a revolution in air technology
When in 1873 Jules Verne published his novel of planet-trotting high adventure, the world was on the verge of an explosion in global travel. New trans-continental railways and the Suez canal promised an increas ...
Leaky, star-forming galaxies lead researchers to better understand the universe
By focusing on large, star-forming galaxies in the universe, researchers at Johns Hopkins University were able to measure its radiation leaks in an effort to better understand how the universe evolved as ...
A giant among Earth satellites
The International Space Station has been called a stepping stone to other worlds.
Fracking's environmental impacts scrutinised
(Phys.org) —Greenhouse gas emissions from the production and use of shale gas would be comparable to conventional natural gas, but the controversial energy source actually faired better than renewables on some environmental ...
The ozone hole has stabilized—some questions remain
The production and consumption of chemical substances threatening the ozone layer has been regulated since 1987 in the Montreal Protocol. Eight international expert reports have since been published, which ...
Scientists say the ozone layer is recovering
Earth's protective ozone layer is beginning to recover, largely because of the phase-out since the 1980s of certain chemicals used in refrigerants and aerosol cans, a U.N. scientific panel reported Wednesday ...
Greenhouse gases: A new group of soil micro-organisms can contribute to their elimination
INRA research scientists in Dijon have shown that the ability of soils to eliminate N2O can mainly be explained by the diversity and abundance of a new group of micro-organisms that are capable of transforming it into atmospheric ...
Mysterious source of ozone-depleting chemical baffles NASA
A chemical used in dry cleaning and fire extinguishers may have been phased out in recent years but NASA said Wednesday that carbon tetrachloride (CCl4) is still being spewed into the atmosphere from an unknown ...
Not just cool – it's a gas
In space, a new way of producing gas is being tested for steering satellites. On Earth, it is now fighting fires without harming the environment – and business insiders say it could be revolutionary.
'Safer' pesticide could create toxic mercury, study says
A compound in pesticides that replaced another banned for its harmful effects, may threaten humans and wildlife by reacting with mercury in natural water to form a toxic chemical, researchers said Tuesday.
Tapping the shale
Growth in scientific knowledge seems to lead to an exacerbation in debate over politically sensitive issues rather than resolution? Nuclear power, global warming, vaccination, creationism, fracking… the list goes on.
Sulfur signals in Antarctic snow reveal clues to climate, past and future
Sulfur signals in the Antarctic snow have revealed the importance of overlooked atmospheric chemistry for understanding climate, past and future.
Is the ozone layer on the road to recovery?
(Phys.org)—Satellites show that the recent ozone hole over Antarctica was the smallest seen in the past decade. Long-term observations also reveal that Earth's ozone has been strengthening following international ...
