A system developed by chemical engineers might present a method of repeatedly eradicating carbon dioxide from a stream of waste gases, and even from the air. The important thing part is an electrochemically assisted membrane whose permeability to gasoline will be switched on and off at will, utilizing no shifting ...

Scientists have accomplished one of many largest and longest examinations to hint unprocessed nitrate motion in forests. The staff discovered that some nitrate sometimes strikes too quick for organic uptake, leading to 'unprocessed' nitrate bypassing the in any other case efficient filter of forest biology.

In one of many coldest, driest locations on Earth, scientists have developed a potential reply to a longstanding thriller concerning the chemistry of streamflow, which can have broad implications for watersheds and water high quality world wide.

Influenza is very contagious and simply spreads as individuals transfer about and journey, making monitoring and forecasting flu exercise a problem. Whereas the CDC constantly screens affected person visits for flu-like sickness within the US, this data can lag as much as two weeks behind actual time. A brand new ...

Concerns over hydraulic fracturing, an oil and gas extraction method that injects millions of gallons of freshwater and chemicals into shale, have largely focused on potential impacts on water quality. But, as scientists now report, 'fracking' operations could have impacts on water quantity because they are withdrawing these large amounts ...
