On Vancouver Island, karst researchers hustle to save one of Earth’s most underappreciated—and fragile—ecosystems: an ecosystem hidden in plain sight. By Bruce Grierson.

Despite what dentists keep telling us about the protective effects of fluoride on people's teeth, virulent myths insisting otherwise somehow manage to persist.

Plants can find it tough to get all the nitrogen they need, especially from Australian soils. But summer storms can provide an added boost.

“It fascinates me how people congregate around even the smallest bodies of water.”

Every 4th grade student knows that more than 70 percent of the earth is covered in water, but how many of us know that a significant portion of our planet’s water is already undrinkable?

Brace yourself for one of the biggest wealth booms ever as early investors ride this healthy beverage explosion that’s capturing billions from
the $74.3 billion dollar soda industry.

A busy university professor didn't have time to work closely with his high school student intern. So he sent her off to figure out her own project...

The unhealthy smog that settled over Beijing earlier this year, capturing international media attention, is not the only visible sign of China's rapid economic growth and the resulting environmental hazards. Countless rivers and lakes have also been contaminated by nearby factories, and sometimes, dumping by local residents.

We’re in an age when scientists can detect the infinitesimally tiny particles that endow atoms with mass and are probing some of the deepest mysteries of biology, such as how experiences and memories can be passed down through an organism’s genes. Thus, it may come as a surprise that we still don’t understand the mechanics of a relatively simple natural phenomenon: snow.

Massive reserves of “freshwater” are buried beneath the seabed on continental shelves around the world, including off Australia, China, North America and South Africa. This is the conclusion of a new study by a team of Australian scientists that appears in this week’s issue of the journal, Nature.

Video explores what happens when a stream of water is exposed to an audio speaker producing a loud 24hz sine wave.

Researchers say they have discovered a large reservoir of melt water that sits under the Greenland ice sheet all year round. The scientists say the water is stored in the air space between particles of ice, similar to the way that fruit juice stays liquid in a slush drink. The aquifer, which covers an area the size of Ireland, could yield important clues to sea level rise.

Greenland can either slow the effects of climate change or could drastically raise sea levels. Researchers at the University of Utah said that lake, known as "perennial firn aquifer," remains liquid year-round despite the otherwise frozen landscape around it, according to English.chosun.com.

Who knew that our ocean currents were constantly painting Van Gogh's Starry Night across the planet? This visualization, created by NASA's Goddard Space Flight Center Scientific Visualization Studio, captures the surface currents that danced and twisted across Earth's oceans from June 2005 through Decmeber 2007 while transporting heat and carbon through the waters.

Nearly 200,000 people in West Virginia awoke Friday to warnings about their tap water: Don't drink it. Don't cook with it. Don't even brush your teeth.

Professional photographer Tim Tadder gathered a bunch of awesome bald men and hurled water balloons at their heads to capture the explosion of water at various intervals. He named this project "Water Wigs."

How long can 300,000 people go without potable water? A chemical spill by a coal facility has left a big swath of West Virginia in an unthinkable state—with no end in sight.

The site of a West Virginia chemical spill that contaminated the water supply for 300,000 people operated largely outside government oversight, highlighting gaps in regulations and prompting questions on whether local communities have a firm grasp on potential threats to drinking water.

How regulators allowed chemicals to literally slip through the cracks and threaten the water supply.
