Fliteboard has just launched its second generation of electric hydrofoil boards, promising improved performance and new bells and whistles across the entire lineup, along with exciting new ride options for advanced users.

Although ozone is used to disinfect water in settings such as treatment plants, the required equipment is typically too large for use in small appliances like water coolers. A new miniaturized ozone generator, however, may be about to change that.

Scientists at Brown University have demonstrated a promising new water purification technology that takes advantage of the tiny gaps in stacked sheets of graphene to filter out contaminants with great efficiency.

A research team from the National University of Singapore has developed a promising aerogel that turns airborne water molecules into drinkable liquid, without needing a power source or having any moving parts.

Howe Industries has submitted the design for a solar-powered steam rocket engine for propelling CubeSats to the National Science Foundation. With only two moving parts, ThermaSat uses a thermal condenser to flash boil water into superheated steam.

A new study by scientists at the University of Colorado has examined the role increased water intake can play in obesity, and found that it can work to reduce the condition in mice by suppressing a key hormone called vasopressin.

Weight is a premium on space launches, so the less we have to take with us, the better. Now engineers have developed a new electrolysis device that may be able to convert very salty Martian water into breathable oxygen and hydrogen for fuel.

Scientists at the Department of Energy’s Lawrence Berkeley National Laboratory have produced a material they say can selectively capture specific heavy metals from wastewater, and do so with unmatched speed and precision down to the atomic level.

Mars may be incredibly dry and dusty today, but evidence is piling up that it was once a watery world. Now the Curiosity rover has found signs of an ancient flood of biblical proportions, most likely kicked off by a climate-changing asteroid impact.

While reverse osmosis is a relatively energy-efficient form of seawater desalination, it is nonetheless made less efficient by a problem known as biofouling. A new membrane coating, however, could address biofouling like never before.

Jupiter’s moon Europa is a fascinating world, with a global subsurface ocean encased in an icy shell and plumes of water that vent into space. A new study has simulated how these plumes might originate, revealing a surprisingly dynamic ice ball.

While double-glazed windows do help save energy, scientists have tweaked the concept to make it even more effective. Instead of leaving an air gap between the two panes of glass, the researchers have inserted a heat-absorbing, light-blocking liquid.
