Scientists Reveal How to Replenish Earth's Vital Groundwater

Groundwater provides about half of the world's population with drinking water and nearly half of all water used to irrigate crops. It can take decades or even centuries for some aquifers to recover after they are depleted.

Astronomers spot water vapor in region where planets likely form

Astronomers have found water vapor around a young star within the constellation Taurus, 450 light-years away from Earth.

Discovery changes understanding of water history on the Moon

New research shows the early lunar crust which makes up the surface of the Moon was considerably enriched in water more than 4 billion years ago, counter to previously held understanding. 

Earth's freshwater is getting saltier, and people are to blame

Human activities are making the globe saltier, specifically in our soils, fresh water and air, according to a new study. The excess salt has already caused serious issues in freshwater supplies in recent decades.

In a surprising finding, light can make water evaporate without heat

The phenomenon might play a role in the formation and evolution of fog and clouds, and thus would be important to incorporate into climate models to improve their accuracy.

Scientists discover the origin of water in our solar system

New findings suggest the water originates from the space between solar systems, billions of years before the birth of our sun.

Scientists Transformed Pure Water Into a Metal

By bringing pure water into contact with an electron-sharing alkali metal – in this case an alloy of sodium and potassium – free-moving charged particles can be added, turning water metallic. 

Earth may have been wet since it formed

A new study finds that Earth's water may have come from materials that were present in the inner solar system at the time the planet formed - instead of far-reaching comets or asteroids delivering such water.

Theia, who brought the water to Earth and ... our Moon

Where does the water on Earth come from? How was our Moon formed? And is there one single event that had led to the formation of both? 

Simple, solar-powered water desalination

A completely passive solar-powered desalination system could provide more than 5,5 liters of fresh drinking water per hour. Such systems could potentially serve off-grid arid coastal areas to provide an efficient, low-cost water source.

Water that never freezes

Swiss researchers have now identified an unusual way to prevent water from forming ice crystals, so even at extreme sub-zero temperatures it retains the amorphous characteristics of a liquid.

Liquid metal discovery to make toxic water safe and drinkable

Researchers have discovered a revolutionary and cheap way to make filters that can turn water contaminated with heavy metals into safe drinking water in a matter of minutes.

Major shifts in global freshwater

A new global, satellite-based study of Earth's freshwater found that Earth's wet areas are getting wetter, while dry areas are getting drier.

World's fastest water heater - 100,000 degrees in a tenth of a picosecond

Scientists have used a powerful X-ray laser for an experimental set-up that produced an exotic state of water. Researchers hope to learn more about the peculiar characteristics of Earth's most important liquid.

Why the world needs to recycle its wastewater

World Water Day is drawing attention to the growing threat of water scarcity. Some countries are making the most of every drop they use – but others are still squeamish about reusing wastewater.
