This hydrogel tablet can purify a liter of river water in an hour

As much as a third of the world's population does not have access to clean drinking water, according to some estimates, and half of the population could live in water-stressed areas by 2025. Finding a solution to this problem ...

Identifying compound classes through machine learning

Everything that lives has metabolites, produces metabolites and consumes metabolites. These molecules arise as intermediate and end products from chemical processes in an organism's metabolism. Therefore, they not only have ...

Mystery of glacial lake floods solved

A long-standing mystery in the study of glaciers was recently —- and serendipitously—solved by a team led by University of Hawai'i at Mānoa astrobiologist and earth scientist Eric Gaidos. Their findings were published ...

Pair of massive baby stars swaddled in salty water vapor

Using the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers spotted a pair of massive baby stars growing in salty cosmic soup. Each star is shrouded by a gaseous disk which includes molecules of sodium chloride, ...

Artificial intelligence learns continental hydrology

Changes to water masses which are stored on the continents can be detected with the help of satellites. The data sets on the Earth's gravitational field which are required for this, stem from the GRACE and GRACE-FO satellite ...

Newer PFAS compound detected for first time in Arctic seawater

Per- and polyfluoroalkyl substances (PFAS), found in many household products and food packages, have raised concerns because of their persistence and possible toxicity to people and wildlife. Because the compounds don't break ...

Winds spread PFAS pollution far from a manufacturing facility

Concerns about environmental and health risks of some fluorinated carbon compounds used to make non-stick coatings and fire-fighting foams have prompted manufacturers to develop substitutes, but these replacements are increasingly ...
