Mussels and other mollusks usually aren't thought of as being all that active. Recently, however, scientists have documented a water-squirting behavior in just one species, which is apparently using the action to give its larvae a fighting chance.

In a highly unexpected approach to renewable energy, researchers in Korea have developed a low-cost, easily-manufactured advanced membrane that actually generates electricity as it turns wastewater, seawater or groundwater into drinking water.

Solar stills provide a clever and simple means of purifying dirty or salty water, but they work at a rather slow rate. A new material has been shown to boost their performance, and it's made from fruit waste which would otherwise be discarded.

Hydrapak's new Flux+ packs water filtration capability into one of the most portable collapsible bottles out there. It carries 1.5 L of water into the wild, refills and filters from natural sources, and packs tiny when it's not in use.

Mercury can be quite harmful in large amounts, and detecting its presence in foods or liquids typically requires lab-based tests. A new nanosensor, however, can quickly detect even small levels of the heavy metal onsite, simply by tapping on samples.

Although we've seen a number of systems that use sunlight to purify tainted water, their output is often quite limited. A new loofah-inspired hydrogel, however, uses sunlight to treat much more water in one go … enough to meet a person's daily needs.

Ice and water aren't very exciting to most of us, but they’re super strange from a scientific standpoint. Researchers have now discovered a brand new type of ice that’s described as being a true “snapshot” of water, and may be found on alien worlds.

Solar panels can’t operate efficiently if they’re caked in dirt, but cleaning them regularly can be a time-consuming process. Engineers in Germany have now developed an ultra-thin coating that can make solar panels and other surfaces self-cleaning.
-
Scientists in Australia have developed an intriguing new technique for removing toxic “forever chemicals” from water. Adding a solution to contaminated water coats the pollutants and makes them magnetic, so they can easily be attracted and isolated.
-
NASA’s Curiosity rover has discovered opal on Mars. The deposits may prove to be valuable to future Martian explorers not as jewelry but as a potential source of water.
-
A fascinating study from researchers at the National Institutes of Health suggests people who don't drink enough fluids could be at greater risk of chronic disease and are more likely to die at a younger age.

Microplastics are a growing environmental problem, but now researchers in Korea have developed a new water purification system that can filter out these tiny fragments, as well as other pollutants, very quickly and with high efficiency.
