Scientists braved ticks and a tiger to discover how human activities have perturbed the nitrogen cycle in tropical forests. Studies at two remote Smithsonian Institution Global Earth Observatory sites in Panama and Thailand show the first evidence of long-term effects of nitrogen pollution in tropical trees.
U.S. lawns cover an area almost as large as Florida, making turfgrass our largest ‘crop’ and lawn fertilizer use a legitimate issue.
Hybrid cars, powered by a mixture of gas and electricity, have become a practical way to "go green" on the roads. Now researchers at Tel Aviv University (TAU) are applying the term "hybrid" to power plants as well.
Some people may consider them pests, but ants are key to many plants’ survival.
The source of arsenic in India's groundwater continues to elude scientists more than a decade after the toxin was discovered in the water supply of the Bengal delta in India. But a recent study with a Kansas State University geologist and graduate student, as well as Tulane University, has added a twist -- and furthered the mystery.
Over the past decade, the populations of staghorn and elkhorn corals in the Florida Keys National Marine Sanctuary have remained steady after dramatic declines in the last century. Long-term monitoring conducted by researchers from the University of North Carolina - Wilmington (UNCW), has revealed that while populations of the iconic branching corals remain far below their historic numbers, the surviving populations of both species have not suffered further declines.
Pollution is making Arabian Sea cyclones more intense, according to a study in this week's issue of the journal Nature.
Flooding events in 2011 and previous years have greatly impacted America’s prime farmland. Floodwaters left sediment and debris, eroded large parts of producers’ fields and, in many cases, left land devastated.
Both climate change and humans were responsible for the extinction of some large mammals, according to research that is the first of its kind to use genetic, archeological, and climatic data together to infer the population history of large Ice-Age mammals.
In an effort to reduce human exposure to harmful chemicals, the EPA is taking the necessary steps by lifting certain rodent repellent products from store shelves.
One set of human-created gases is starting to relinquish its hold on Antarctic climate as another group of emissions produced by human activity is starting to take hold, according to a paper in Nature Geoscience, co-authored by ARC Laureate Fellow Professor Matthew England, co-director of the UNSW Climate Change Research Centre.
Increasing competition and reducing the role of the state in Greece’s energy sector could make a significant contribution to the country’s economic recovery, according to a review of Greek energy policies published today by the International Energy Agency (IEA).
Solar power may be on the rise, but solar cells are only as efficient as the amount of sunlight they collect. Under the direction of a new professor at Northwestern University's McCormick School of Engineering and Applied Science, researchers have developed a new material that absorbs a wide range of wavelengths and could lead to more efficient and less expensive solar technology.
Urine can be an abundant fuel for electricity generation, according to British scientists in the first study of its kind.
The Environmental Protection Agency (EPA) has awarded People, Prosperity and the Planet (P3) Phase I grants for the 2011-2012 school year. The grants were awarded to 45 teams of college and university students across the country.
More than half of eastern U.S. tree species examined in a massive new Duke University-led study aren't adapting to climate change as quickly or consistently as predicted.
The study, published in the journal Nature Communications, is the first to investigate the effect of drainage on carbon accumulation in northern peatlands and the vulnerability of that carbon to burning.
The days are getting shorter and the temperatures are dropping - do you know what that means? Time to break out the coats and turtle necks for the winter season. It can also mean increased energy consumption and higher electricity bills for businesses and consumers.
Action protects public health and cuts harmful emissions from Pennsylvania power plant.
Hydrogen offers great promise as a renewable energy source. It's staggeringly plentiful (the most abundant element in the Universe) and environmentally friendly (used in a fuel cell, it gives off only water). Unfortunately, storing and transporting hydrogen for personal use is a significant engineering challenge.
