Reusable microbots make meal of toxic metals

Researchers have developed a tube-shaped microbot that offers a cheaper and more effective way of removing heavy metals than previous methods. The self-propelled microbots use an outer layer of graphene that binds to lead ions it comes in contact with. The scientists found that they can remove 95 percent of lead from polluted water in one hour, and once they have a full payload, they can be cleaned and reused multiple times.Read More

Is the water in your local lake clean enough to swim in today? Currently, the only way to find out is for someone to take a water sample, bring it back to a lab, then report the analysis 24 to 48 hours later. Soon, however, water-sampling buoys anchored off of beaches could provide readings in real time.Read More

Planes, ships and ground stations working together to study pollution

Next week, an international effort between NASA and the Republic of Korea's National Institute of Environmental Research (NIER) will see the two bodies working together on an ambitious, six-week set of observations designed to improve our understanding of air pollution. The project will include the use of three planes housing 37 different instruments, and more than 300 ground sites, working together to gather data that help in the development of new solution to combat poor air quality across the globe.Read More

Ocean-friendly Seabin sucks up surrounding sea trash

The mounting plastic waste in the world's oceans has been the subject of of some pretty bold environmental undertakings, perhaps none more so than the Ocean Cleanup Project aiming to eradicate the Great Pacific Garbage Patch. The Seabin Project represents a smaller-scale approach, but it is noble in its aspirations all the same. Installation in ports and marinas sees this ocean-friendly trash can suck up the surrounding debris and even remove oil from the water.Read More
