Without plants, Earth would cook under billions of tons of additional carbon
(Phys.org) —Enhanced growth of Earth's leafy greens during the 20th century has significantly slowed the planet's transition to being red-hot, according to the first study to specify the extent to which ...
Cutting specific pollutants would slow sea level rise, research says
With coastal areas bracing for rising sea levels, new research indicates that cutting emissions of certain pollutants can greatly slow down sea level rise this century.
Microbe's innovation brought doom to Earth
The physical environment can produce sudden shocks to the life of our planet through impacting space rocks, erupting volcanoes and other events.
Progress on detecting glucose levels in saliva
Researchers from Brown University have developed a new biochip sensor that can selectively measure concentrations of glucose in a complex solution similar to human saliva. The advance is an important step ...
Earth's breathable atmosphere a result of continents taking control of the carbon cycle
Scientists investigating one of the greatest riddles of the Earth's past may have discovered a mechanism to help determine how oxygen levels in the atmosphere expanded to allow life to evolve.
Ancient forests stabilized Earth's CO2 and climate
UK researchers have identified a biological mechanism that could explain how the Earth's atmospheric carbon dioxide and climate were stabilised over the past 24 million years. When CO2 levels became too low fo ...
Team develops side-illuminated ultra-efficient solar cell designs
Researchers at Ben-Gurion University of the Negev (BGU) have developed a radically new design for a concentrator solar cell that, when irradiated from the side, generates solar conversion efficiencies which ...
New technique can help nanoparticles deliver drug treatments
A Wayne State University researcher has successfully tested a technique that can lead to more effective use of nanoparticles as a drug delivery system.
NASA study projects warming-driven changes in global rainfall (w/ Video)
(Phys.org) —A NASA-led modeling study provides new evidence that global warming may increase the risk for extreme rainfall and drought.
Biochip measures glucose in saliva, not blood
For the 26 million Americans with diabetes, drawing blood is the most prevalent way to check glucose levels. It is invasive and at least minimally painful. Researchers at Brown University are working on a ...
Same protein that fires up cancer-promoting Erk also blocks its activation
A protein which is intimately involved in cancer-promoting cell signaling also keeps a key component of the signaling pathway tied down and inactive, a team led by scientists from The University of Texas MD Anderson Cancer ...
Researchers document acceleration of ocean denitrification during deglaciation
As ice sheets melted during the deglaciation of the last ice age and global oceans warmed, oceanic oxygen levels decreased and "denitrification" accelerated by 30 to 120 percent, a new international study ...
Study pinpoints causes of 2011 Arctic ozone hole
(Phys.org) —A combination of extreme cold temperatures, man-made chemicals and a stagnant atmosphere were behind what became known as the Arctic ozone hole of 2011, a new NASA study finds.
New study documents the natural relationship between CO2 concentrations and sea level
By comparing reconstructions of atmospheric CO2 concentrations and sea level over the past 40 million years, researchers based at the National Oceanography Centre, Southampton have found that greenhouse gas concentrations ...
