Increased levels of radon in Pennsylvania homes correspond to onset of fracking
Johns Hopkins Bloomberg School of Public Health researchers say that levels of radon in Pennsylvania homes - where 42 percent of readings surpass what the U.S. government considers safe - have been on the ...
Study shows increase of CO2 in the atmosphere is lower than predicted because of plants
Climate change caused by ocean, not just atmosphere, study finds
Most of the concerns about climate change have focused on the amount of greenhouse gases that have been released into the atmosphere.
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 ...
A glucose meter of a different color provides continuous monitoring
(Phys.org) —University of Illinois engineers are bringing a touch of color to glucose monitoring.
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 ...
