Wrinkled graphene sheets offer a shortcut for water purification

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. The technology overcomes one of the key… Continue reading Wrinkled graphene sheets offer a shortcut for water purification

Sponge-like aerogel turns airborne vapor into drinkable water

Water security is a significant problem and pulling it out of the air, as fanciful as that may sound, is shaping as a potential part of the solution. A team from the National University of Singapore (NUS) has put forward a promising example of this typ… Continue reading Sponge-like aerogel turns airborne vapor into drinkable water

Increased water intake suppresses key hormone to reduce obesity in mice

It is known that drinking water and staying hydrated is an important part of staying healthy, but not so well known are the intricate mechanisms by which a little H20 improves our physiological state. A new study has examined the role increased water i… Continue reading Increased water intake suppresses key hormone to reduce obesity in mice

New electrolyzer could make hydrogen and oxygen out of salty Mars water

Weight is a premium on space launches, so the less we have to take with us, the better. Now, engineers at Washington University in St. Louis have developed a new electrolysis device that may be able to convert very salty Martian water into breathable o… Continue reading New electrolyzer could make hydrogen and oxygen out of salty Mars water

New material cleans copper from wastewater with unmatched efficiency

Treating wastewater to cleanse it of contaminants like heavy metals is a complex task, and one that often involves a slow-going, scattergun approach. Scientists at the Department of Energy’s Lawrence Berkeley National Laboratory have now produced a mat… Continue reading New material cleans copper from wastewater with unmatched efficiency

Curiosity finds evidence of ancient megaflood on Mars

Mars may be incredibly dry and dusty today, but evidence continues to pile up that it was once a very watery world. Now the Curiosity rover has found signs of an ancient flood of biblical proportions, most likely kicked off by a climate-changing astero… Continue reading Curiosity finds evidence of ancient megaflood on Mars

New coating could make desalination tech more efficient and less toxic

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.Continue ReadingCa… Continue reading New coating could make desalination tech more efficient and less toxic

Europa’s plumes may not originate from subsurface ocean

Jupiter’s moon Europa is a fascinating world, with a global subsurface ocean encased in an icy shell and plumes of water vapor that vent into space. A new study has simulated how these plumes might originate, revealing a surprisingly dynamic ice ball.C… Continue reading Europa’s plumes may not originate from subsurface ocean
