Sun-powered water filter excels at killing pathogens

There are many parts of the world in which fresh water may be plentiful, but it’s also full of harmful microbes. An experimental new filter is able to purify such water for drinking, and it’s powered solely by sunlight.Continue ReadingCategory: Good Th… Continue reading Sun-powered water filter excels at killing pathogens

Low-cost student-designed filter removes lead from tap water

Lead-contaminated tap water is still a problem in much of the world, where conventional lead removal filters may be too expensive for most households. An inexpensive new filter could help – and it was designed by a group of high school students.Continu… Continue reading Low-cost student-designed filter removes lead from tap water

To remove microplastics from drinking water … just add okra?

If you’ve ever eaten okra, then you’ll know that the stuff can be pretty … gooey. According to new research, that quality could allow a compound from the plant to be used in a less toxic method of removing microplastics from drinking water.Continue Rea… Continue reading To remove microplastics from drinking water … just add okra?

Could wax-coated sand replace plastic mulch in farmers’ fields?

Farmers will often place sheets of plastic on the ground along their crop rows, in order to help hold moisture in the soil. According to a new study, however, the use of wax-coated sand may be a cheaper and greener way to go.Continue ReadingCategory: S… Continue reading Could wax-coated sand replace plastic mulch in farmers’ fields?

Strange new form of ice discovered in high pressure experiments

Ice may seem pretty simple in our everyday experience, but it actually comes in at least 20 different forms. Scientists at the University of Nevada Las Vegas (UNLV) have now discovered a new type of ice that may be found deep in the Earth’s mantle or o… Continue reading Strange new form of ice discovered in high pressure experiments

Eco-friendlier hydroelectric tech would swap dams for electric trucks

While hydroelectric dams are capable of generating a lot of electricity, they drastically disrupt the environment. Scientists have now proposed a simpler but still effective alternative, in which electric trucks replace such dams.Continue ReadingCatego… Continue reading Eco-friendlier hydroelectric tech would swap dams for electric trucks

Salty hydrogel sucks liters of drinking water a day out of thin air

A shortage of drinking water is a key problem in many parts of the world, and it’s a cruel irony that huge amounts are floating around in the air, inaccessible. Researchers at the University of Texas at Austin have now developed a salty hydrogel that c… Continue reading Salty hydrogel sucks liters of drinking water a day out of thin air

Hybrid system produces electricity and irrigation water in the desert

In remote desert locations, at least two things are likely to be lacking: an electrical grid, and a source of water for agriculture. An experimental new system addresses both problems, by combining photovoltaic panels with an absorbent hydrogel.Continu… Continue reading Hybrid system produces electricity and irrigation water in the desert
