Water

While certain types of filtration media are great at removing pathogens from water, they do clog up over time, slowing their rate of filtration. According to new research, a solution to the problem may lie in the use of "living filtration membranes."

Scientists have developed an advanced new type of humidity sensor inspired by camel noses that is capable of detecting low levels of water molecules in the air, giving it the potential to help find water sources in extreme environments.

Data from China's Chang'E-5 lunar lander analyzed by an international team led by the Chinese Academy of Sciences shows that the robotic spacecraft has, for the first time, detected traces of water in the rocks and regolith on the Moon's surface.

A huge deposit of water has been discovered on Mars in a formation often called its Grand Canyon. The Trace Gas Orbiter has detected an area the size of the Netherlands where water could make up as much as 40 percent of the material near the surface.

We all learned in elementary school science that water freezes at 0 °C – but it’s actually not quite that simple. New experiments have shown that tiny droplets can remain liquid right down to -44 °C, if kept in contact with a soft surface.

Accounting for where all of the Earth's water came from is a longstanding puzzle, but an international team of scientists led by the University of Glasgow has proposed that the Sun may be a major source of our planet's H₂O.

Adhesives that hold underwater are elusive, but could be useful for marine repairs or tissue healing. Researchers have now developed a new type of adhesive hydrogel that combines the underwater stickiness of mussels with the strength of spider silk.

Watergen has long been working to refine and grow technology to pull water vapor out of the air and collect it for drinking. Its latest innovations shrink that water-harvesting tech into a form portable enough for overlanders and RVers.

The burning of coal may be falling out of favor as a means of generating heat and electricity, but that doesn't mean the material no longer has any valuable uses. According to a new study, it could be utilized in the desalination of seawater.

Water can take on far more forms than many people give it credit for, and now scientists have recreated a particularly bizarre one in the lab – a “hot black ice” that may exist deep inside planets like Uranus and Neptune.

When sourcing drinking water in the great outdoors it can pay to take no chances, and a new line of bottles co-developed by CamelBak and Lifestraw is one designed to keep risk of contamination to a minimum.

Access to clean water is a major unmet need in many parts of the world. Researchers at the University of Texas at Austin have developed a new hydrogel tablet that could help, with a prototype able to disinfect a liter of river water in one hour.
