Water

The new Level Board electric hydrofoil is very much aimed at the beginner end of the spectrum, offering a gentle learning curve for newcomers by using aerospace-grade sensors and a flight computer to keep the board stable across the water.

The James Dyson Award is an international competition to encourage students to get creative to solve the world's pressing problems. The national finalists have been announced for 2021, showcasing ideas that help people and the environment.

By using cutting-edge tools to study microscopic jets of the liquid, scientists have spotted water molecules pushing and pulling on each other in what is described as a "quantum tug," a phenomenon that has never been directly observed before.

Carbon dioxide in the atmosphere attracts most of the attention in environmental concerns, but much of that ends up in oceans, making them more acidic. Now scientists have created nanojars that can easily capture this and other pollutants from water.

NASA’s Curiosity rover has been exploring Gale crater for nine years, studying sediments that look an awful lot like those left behind from an ancient lake. But new research from the University of Hong Kong proposes a much drier explanation.

MIT researchers have found yet another use for the over-achieving wonder material graphene, by making a reusable filter out of graphene oxide foam that acts like a magnet for uranium, effectively pulling the radioactive element out of drinking water.

Nuclear and fossil fuel power plants consume huge amounts of water for cooling, which then goes to waste as water vapor. MIT engineers have now developed a system that can capture and recycle that lost water.

In many arid regions, people use devices known as solar stills to extract drinkable water from seawater or tainted water. A new type of solar still is claimed to be much more effective than others, by incorporating a rotating cylinder.

In 2018 astronomers announced the discovery of lakes of liquid water on Mars at the south pole. Sadly, a trio of new papers refutes the claim, with new experiments suggesting that the “water” signal was more likely produced by frozen clay instead.

When we hear about smartphones being used to perform analytical tasks, there's often also a device that's connected to the phone. According to a new study, though, a phone's own touchscreen could soon be used to test drinking water and other liquids.

The vast majority of water on Earth is undrinkable, but desalination could be a vital technology to meet the world’s drinking water needs. Now, Korean engineers have developed a new nanofiber membrane that can operate efficiently for long periods.

New modeling of water activity on different solar system planets has found that Venus would be too dry for even the most extreme forms of life – but there may be other contenders in our solar system that we hadn’t considered.
