Electric cars that exist today could be widely adopted despite range constraints, replacing about 90 percent of existing cars, and could make a major dent in the nation's carbon emissions, new research indicates.The study, which found that a wholesale replacement of conventional vehicles with electric ones is possible today and could play a significant role…

Researchers have flown aircraft over an oil and gas field and pinpointed — with unprecedented precision — sources of the greenhouse gas methane in real time. The technique led to the detection and immediate repair of two leaks in natural gas pipelines in the Four Corners region of the U.S. Southwest.The technique led to the…

This year is on track to see Americans’ consumption of bottled water outpace their soda drinking for the very first time. According to Euromonitor, a market research firm, the average American will buy 27.4 gallons of bottled water, compared to 26.2 gallons of soda drinks.Is this a good thing? It’s hard to argue that less consumption of…

Our planet is nestled in the center of two immense, concentric doughnuts of powerful radiation: the Van Allen radiation belts, which harbor swarms of charged particles that are trapped by Earth's magnetic field. On March 17, 2015, an interplanetary shock – a shockwave created by the driving force of a coronal mass ejection, or CME,…

Future climate warming will likely cause only minor cuts in energy output at most U.S. coal- or gas-fired power plants, a new Duke University study finds.The study — the first of its kind based on real-world data — rebuts recent modeling-based studies that warn rising temperatures will significantly lower the efficiency of power plants' cooling…

Ever thought of putting sewage on your plants? Scientists say thermally conditioned sewage sludge serves as an excellent fertilizer to improve soil properties. This was recently published in the open-access journal Frontiers in Nutrition. The major advantage over commercial fertilizers? Sustainable re-use of essential and finite phosphorus resources.Phosphorus is a key nutrient for all living beings.…

A team of scientists from the Department of Energy's Oak Ridge National Laboratory and the University of Florida has developed a novel method that could yield lower-cost, higher-efficiency systems for water heating in residential buildings.The theory behind the newly termed "semi-open" natural gas-fired design, explained in an ORNL-led paper published in Renewable Energy: An International Journal,…

In many parts of the world, the only way to make germy water safe is by boiling, which consumes precious fuel, or by putting it out in the sun in a plastic bottle so ultraviolet rays will kill the microbes. But because UV rays carry only 4 percent of the sun's total energy, the UV…

The balmy waters of the Caribbean could turn into a deadly heat trap for countless tiny creatures. Authors of a new study conducted at the Smithsonian Tropical Research Institute (STRI) in Panama discovered that microscopic sea urchin eggs and larvae may suffer stunting or death when the water temperature spikes just a couple of degrees…

You've seen it when flying into major cities the world over: a haze over the city. It is caused by aerosol particles, but scientists don't know all the details of the complex chemistry involved. At Pacific Northwest National Laboratory, Dr. Alla Zelenyuk and her team took on a specific part of that haze: originated from…
