Solar evaporator offers a fresh route to fresh water

About a billion people around the world lack access to safe drinking water. Desalinating salty water into drinkable water can help to fill this dangerous gap. But traditional desalination systems are far too expensive to ...

Making lead pipes safe

Lead leaching from pipes into the water supply is a serious public health concern. And if water sources or treatment regimens are changed, the new chemistry can cause water distribution systems that were previously safe to ...

How to ice-proof the next generation of aircraft

35,000 feet is standard cruising altitude for a commercial jet airplane, but at those lofty heights the air temperature plummets below -51 degrees Celsius and ice can easily form on wings. To prevent ice formation and subsequent ...

Researchers unveil effects of dust particles on cloud properties

An international team led by Japanese scientists has generated significant findings that highlight the impact of high-latitude dust on the conversion of water droplets in clouds into ice—or glaciation—within low-level ...

Peru fighting mining pollution with little green algae

Scientists in Peru have removed small green algae from polluted lakes and rivers in a bid to strengthen them with nutrients and oxygen before returning them to purify those water bodies from harmful mining waste.

High-energy X-ray bursts from low-energy plasma

Solar flares shouldn't produce X-rays, but they do. Why? The one-size-fits-all approach to electron collisions misses a lucky few that lead to an intense X-ray burst. Scientists thought there were too many electron-scattering ...

NASA catches Tropical Cyclone Gelena's post-tropical transition

Tropical cyclones can become post-tropical before they dissipate, meaning they can become sub-tropical, extra-tropical or a remnant low pressure area.  As Tropical Cyclone Gelena transitioned into a subtropical storm, NASA's ...
