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.

64% of bottled water comes from a tap

As communities around the world promote refill stations and water fountains over bottled water, it's worth revisiting a fact about bottled water: most of it is literally the same water we get out of our faucets.

Cape Town at risk of becoming first major city in the world to run out of water

The drought-stricken city announced that it will begin marking 200 collection points where its 3.7 million residents will be required to queue for a rationed supply of water on ‘Day Zero’ – currently forecast to be April 21, 2018.

Water is able to exist in two liquid states

Scientists have long sought to unravel the mysteries of water, and researchers at Stockholm University say the compound's odd behavior stems from its ability to exist in two, liquid states.

Water conservation turned around sinking in California, US

Silicon Valley rose as water use restrictions kicked in.

Inside tiny tubes, water turns solid when it should be boiling

MIT researchers discover astonishing behavior of water confined in carbon nanotubes.

ORNL researchers discover new state of water molecule

Neutron scattering and computational modeling have revealed unique and unexpected behavior of water molecules under extreme confinement that is unmatched by any known gas, liquid or solid states.

Student-made device could bring clean water to the world

A device built by University of Washington students could help provide clean drinking water to some of the poorest countries in the world for less than $4 each.
