Using math models to make predictions: How vegetation competes for rainfall in dry regions
The greater the plant density in a given area, the greater the amount of rainwater that seeps into the ground. This is due to a higher presence of dense roots and organic matter in the soil. Since water is ...
We may all be Martians: New research supports theory that life started on Mars
New evidence has emerged which supports the long-debated theory that life on Earth may have started on Mars.
An often-overlooked form of manganese, an element critical to many life processes, is far more prevalent in ocean environments than previously known, according to a study led by University of Delaware researchers ...
Pollution blamed for drop in Beijing tourism
The number of tourists visiting China's capital fell by more than 14 percent in the first half of this year compared to 2012, state media reported Saturday, with air pollution blamed for the decline.
Researchers estimate over two million deaths annually from air pollution
Over two million deaths occur each year as a direct result of human-caused outdoor air pollution, a new study has found.
A tale of two cities
Yifang Zhu, an associate professor in the UCLA Fielding School of Public Health, and her colleagues are drawing on lessons from Los Angeles and teaming with Peking University scientists to guide policy makers ...
Excited, but cold: Scientists unveil the secret of a reaction for prebiotic synthesis of organic matter
How is it that a complex organism evolves from a pile of dead matter? How can lifeless materials become organic molecules that are the bricks of animals and plants? Scientists have been trying to answer these ...
China seen facing uphill struggle against pollution
China's newly announced measures to combat pollution by slashing emissions from major polluting industries and holding local officials responsible could take 18 years to bring air quality within acceptable standards, analysts ...
China to hold local leaders responsible for air quality
China has pledged to hold local government leaders responsible for improving air quality, officials said, after heavy smog across China earlier this year stoked social discontent.
Persistence of 'urban' organics downstream favors dead-zone formation
(Phys.org) —Each time it rains, runoff carries an earthy tea steeped from leaf litter, crop residue, soil, and other organic materials into the storm drains and streams that feed Chesapeake Bay.
How satellites could be used to devise a warning system against the disease
Cholera remains one of the most prevalent water-related infections in many tropical regions of the world, specifically coastal areas of South Asia, Africa, and Latin America. We now know how to treat cholera patients, and ...
Studying how flocculation affects acoustic reflection
In inland estuaries and shallow coastal waters, small particles of organic matter, such as organic waste and debris or bacteria, clump together to form an aggregate known as floc. Flocculated particles can span a range of ...
Source of organic matter affects Bay water quality
Each time it rains, runoff carries an earthy tea steeped from leaf litter, crop residue, soil, and other organic materials into the storm drains and streams that feed Chesapeake Bay.
Forest organic runoff breaks down faster than agricultural, urban runoff
Dissolved organic matter in streams and rivers can be broken down by sunlight or bacteria, providing a fuel source for aquatic ecosystems and affecting carbon dioxide and carbon monoxide concentrations as the organic matter ...
