Fog harvesting may look like whimsical work.

After all, installing giant nets along hillsides and mountaintops to catch water out of thin air sounds more like folly than science. However, the practice has become an important avenue to clean water for many who live in arid and semi-arid climates around the world.

Highly complex interactions among roots, fungi and bacteria underlie the ability of some trees to clean polluted land, according to a novel study by bioinformatics and plant-biology experts from McGill University and Université de Montréal.

According to researchers at Aalto University, Finland, large-scale weather cycles, such as the one related to the El Niño phenomenon, affect two-thirds of the world’s cropland. In these so called climate oscillations, air pressure, sea level temperature or other similar factors fluctuate regularly in areas far apart in a way that causes rain and temperature patterns to shift significantly.

High tide floods, or so-called “nuisance flooding,” that happen along shore roadways during seasonal high tides or minor wind events are occurring far more frequently than ever before. Researchers at the University of New Hampshire have found that in the past 20 years roads along the East Coast have experienced a 90 percent increase in flooding – often making the roads in these communities impassable, causing delays, as well as stress, and impacting transportation of goods and services.

Insights into how songbirds learn to sing provide promising clues about human speech disorders and may lead to new ways of treating them, according to new research published in the journal eLife.

It may be only a matter of time before urban dwellers can hail a self-driving taxi, so researchers at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) and UC Berkeley decided to analyze the cost, energy, and environmental implications of a fleet of self-driving electric vehicles operating in Manhattan.

Researchers are working with schools around the county to find 24,000 volunteers aged 16 to 18 years to take part in the Be on the TEAM (Teenagers Against Meningitis) trial, led by the Oxford Vaccine Group at the University of Oxford with funding and support from the National Institute for Health Research (NIHR).

Ragweed, its pollen potent to allergy sufferers, might be more than a source of sneezes. In the Midwest, the plant may pose a threat to soybean production.

A new National Academies of Sciences' report calls on several federal agencies to work together to improve techniques for measuring one of the most important greenhouse gases produced by humans - methane.

In a newly published study, U.S. Geological Survey scientists and their partners calculate possible alert times that earthquake early warning systems can provide people at different levels of ground motion from light to very strong shaking.
