New method targets oil sheen, other pollutantsSmall amounts of oil leave a fluorescent sheen on polluted water. Oil sheen is hard to remove, even when the water is aerated with ozone or filtered through sand. Now, a University of Utah engineer has developed an inexpensive new method to remove oil sheen by repeatedly pressurizing and depressurizing ozone gas, creating microscopic bubbles that attack...

Researchers in MIT's Department of Civil and Environmental Engineering believe they have pinpointed a pathway by which arsenic may be contaminating the drinking water in Bangladesh, a phenomenon that has puzzled scientists, world health agencies and the Bangladeshi government for nearly 30 years. The research suggests that human alteration to the landscape, the construction of villages with ponds,...

(PhysOrg.com) -- Although America's supply of drinking water is considered among the world's safest, there is an urgent need to develop more stringent regulations to guide how water is monitored for pollutants, according to April Gu, assistant professor of civil and environmental engineering at Northeastern University. Gu is working on the fundamental research underlying our ability to identify and...

A new report examines and, when possible, estimates "hidden" costs of energy production and use -- such as the damage air pollution imposes on human health -- that are not reflected in market prices of coal, oil, other energy sources, or the electricity and gasoline produced from them.

The Cambrian Explosion is widely regarded as one of the most relevant episodes in the history of life on Earth, when the vast majority of animal phyla first appear in the fossil record. However, the causes of its origin have been object of debate for decades. A novel theory formulates that the geologically induced increase on marine calcium, as a result of volcanic activity, might be the key for understanding...

Researchers have developed a process that can mix tiny volumes of liquid, even in complicated spaces. The discovery of how to mix tiny liquid volumes arose from research directed at improving the sensitivity of the chemical sensors developed in his lab. While their original project did not lead to the expected results, researchers were surprised by the wide variety of physical effects they discovered...

Just in time for Halloween, researchers have announced the discovery of a new, real-world "monster" -- what they are calling a "unicorn" fly that lived about 100 million years ago and is being described as a new family, genus and species of fly never before observed.

A new "Roadrunner Universe" model requires a petascale computer because, like the universe, it's mind-bendingly large. The model's basic unit is a particle with a mass of approximately one billion suns (in order to sample galaxies with masses of about a trillion suns), and it includes 64 billion and more of those particles. The model is one of the largest simulations of the distribution of...

Why did Barack Obama win the US election and did the fact he is over six feet tall influence the voters? Researchers argue that due to 'a hangover from our evolutionary past' factors like age, sex, height and weight play a major part in the determining our choice of leaders.

As Saturn's rings orbit the planet, a section is typically in the planet's shadow, experiencing a brief night lasting from 6 to 14 hours. However, once approximately every 15 years, night falls over the entire visible ring system for about four days.

The best ways to improve energy security, mitigate global warming and reduce the number of deaths caused by air pollution are blowing in the wind and rippling in the water, not growing on prairies or glowing inside nuclear power plants, says Mark Z. Jacobson, a professor of civil and environmental engineering at Stanford. And "clean coal," which involves capturing carbon emissions and sequestering...

China will divert water from the Yangtse and the Yellow Rivers to help farmers hit by the country's worst drought in decades, state media said Sunday (Feb 8). The action follows the declaration of the highest level of drought emergency by the Office of Flood Control and Drought Relief Headquarters that affected more than 4.3 million people and 2.1 million head of livestock, as parts of the nation experience...
