We often hear of cyanobacteria as being the cause of toxic algae blooms in lakes. Soon, however, a 3D-printed material that incorporates the microbes may be used to purify polluted water – and after the bacteria are finished, they'll kill themselves.

Researchers have found that tire wear and tear is a major contributor to urban waterway pollution, producing particulate matter that includes microplastics. But they also found effective ways of reducing this type of potentially harmful pollution.
-
Fog nets are a literal lifesaver in arid regions with regular fog – but unfortunately they can also capture airborne pollution. Scientists at ETH Zurich have now developed fog nets that can use sunlight to break down hazardous molecules.
-
Researchers may have found an effective, green way to remove microplastics from our water using readily available plant materials. Their device was found to capture up to 99.9% of a wide variety of microplastics known to pose a health risk to humans.

Estrogen can harm aquatic plants and animals when passed into waterways via human and agricultural waste streams. Researchers have now developed a new way of removing the hormone from water, however, using what's known as "smart rust."
-
The new Vitaloop Defender bottle uses an all-in-one design to collect, purify and deliver water. Its five-part filtration system and battery-powered pump turn water from a lake or river into potable drinking water at the push of a button.
-
Commonly known as blue-green algae, toxic cyanobacteria can harm humans and wildlife alike when their populations soar in lakes or rivers. A newly developed sponge, however, could soon help bring such harmful algal blooms under control.
-
NASA's James Webb Space Telescope has scored another first, detecting evidence of water in a planet-forming disc circling another star where at least two terrestrial-class proto-planets seem to be forming.

Regular water-changes are essential to the wellbeing of aquarium fish, but the task sometimes gets missed, plus it can be hard to determine how much water should be replaced, and how often. That's where the automated StayrAI Rein system comes in.

A bright red waterfall isn’t something you’d expect to see on the icy landscape of Antarctica, but that’s what’s pouring out from the foot of Taylor Glacier. Scientists now claim to have solved the mystery behind the crimson waters of Blood Falls.
-
Astronauts on interplanetary missions will be a bit less thirsty after a new NASA system succeeded at reclaiming 98% of waste water aboard the International Space Station (ISS) by converting things like urine into a drinkable state.
-
Chlorine has long been used to disinfect drinking water but has been linked to health problems. In a new study, researchers looked at how the bacteria the purification process was designed to remove responded when chlorine was removed from the equation.
