(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...

What do a West African drummer and a sperm whale have in common? According to some reports, they can both spot rhythms in the chatter of an ocean crowded with the calls of marine mammals -- a feat impossible for the untrained human ear.

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.

A Spanish researcher has analyzed the preferences of wolves from the north east of the Iberian Peninsula to demonstrate that, in reality, their favorite prey are roe deer, deer and wild boar, ahead of domestic ruminants (sheep, goats, cows and horses).

(PhysOrg.com) -- Dr. Jeffery Volz, assistant professor of civil, architectural and environmental engineering at Missouri University of Science and Technology, and his team have received $567,000 to explore how adding carbon fibers could improve the blast and impact resistance of conventional reinforced concrete. The research is funded by the through a cooperative agreement with the Leonard Wood Institute....

Most of the technology needed to shift the world from fossil fuel to clean, renewable energy already exists. Implementing that technology requires overcoming obstacles in planning and politics, but doing so could result in a 30 percent decrease in global power demand, say Stanford civil and environmental engineering Professor Mark Z. Jacobson and University of California-Davis researcher Mark Delucchi....

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...
