Heavy rare earth elements are critical for modern technological applications, but their extraction can have disastrous environmental impacts. Employing electrokinetic mining techniques can increase recovery efficiency while reducing harmful environmental consequences.

While utilities in arid regions are increasingly purifying municipal wastewater as a sustainable water supply, lingering concerns about health risks have hindered implementation. Our recent study indicates that the toxicity of potable reuse waters is equal or lower than conventional drinking waters.

Climate models agree that global mean total precipitable water increases by about 7% per 1°C of global warming. New observations allow us to further support this and to narrow the range in global projections of tropospheric humidity in line with formerly constrained projections of global warming.
