Researchers have discovered that treated wastewater can be used to produce clean hydrogen fuel instead of relying on highly purified fresh water. Green hydrogen is made by splitting water using electricity from renewable sources, but this process usually needs extremely clean water. Treating water to that level is expensive and uses a lot of energy. By using wastewater that has already been treated, scientists found the cost of water preparation could drop sharply while also reducing pressure on limited freshwater supplies.

One major challenge is that wastewater still contains minerals such as calcium and magnesium. These substances can clog the membranes inside electrolyzers, the devices that split water into hydrogen and oxygen. The research team solved this problem by slightly acidifying the water. This simple adjustment improves the movement of hydrogen ions and prevents mineral buildup, allowing the system to operate smoothly for long periods during laboratory testing.

This approach could make green hydrogen cheaper and easier to scale without competing with drinking water. It may help expand hydrogen use in industries like steel and chemicals, where cutting emissions is especially difficult, while making better use of water that would otherwise go to waste.

Astronomers have identified a planet called TOI seven one five b that orbits a small red dwarf about one hundred thirty seven light years away. It measures a little over one and a half times the size of Earth and sits inside what researchers call the conservative habitable zone. This means it receives a level of stellar energy similar to what Earth gets from the Sun which keeps interest high as scientists search for rocky worlds that might sustain liquid water.

What makes this planet especially important is its position inside a mysterious size range known as the small planet gap. Planets rarely appear between one and a half and two Earth radii and those that do can help reveal how young worlds lose mass over time. Some scientists suspect that strong radiation from a nearby star can strip outer layers and shrink planets into this rare zone. Since TOI seven one five b sits in this region it offers a natural laboratory for testing how these sculpting processes unfold around cool red dwarf stars.

Another promising feature is the suitability of this system for detailed atmospheric study with the James Webb Space Telescope. The star is small and the planet circles it every nineteen days creating deep and frequent transits that boost the strength of atmospheric signals. If Webb confirms an atmosphere and identifies its components researchers could learn how this world formed and whether conditions might favor habitability. A second potential planet may also orbit the star which could make this system one of the most valuable nearby targets for future exploration.
