Ancient enzymes can contribute to greener chemistry
(Uppsala University) A research team at Uppsala University has resurrected several billion-year-old enzymes and reprogrammed them to catalyse completely different chemical reactions than their modern versions can manage. The method can be used to develop sustainable solutions within biotechnology, such as for enzyme bioreactors or to chemically degrade environmental toxins. The study has been published in Chemical Science. (Source: EurekAlert! - Biology)

(American Chemical Society) Scientists have detected RNA from the new coronavirus, SARS-CoV-2, in the feces of people with COVID-19. So it stands to reason that the viral RNA could end up in city sewage, where it could be used to monitor prevalence of the disease. Now, researchers reporting in ACS' Environmental Science& Technology Letters have detected rising SARS-CoV-2 RNA levels in sewage from several cities in the Netherlands at early stages of the pandemic.

Considering health when switching to cleaner electricity
(American Chemical Society) Power plants that burn coal and other fossil fuels emit not only planet-warming carbon dioxide, but also pollutants linked to breathing problems and premature death. Policies proposed to mitigate climate change, however, often fail to fully account for the health benefit of switching to cleaner technologies. In a new study published in ACS' Environmental Science& Technology, researchers show that emphasizing health concerns in such policies can alter the optimal locations of these upgrades.   (Source: EurekAlert! - Biology)

Photoelectron spectra of alkali metal-ammonia microjets: From blue electrolyte to bronze metal
Experimental studies of the electronic structure of excess electrons in liquids—archetypal quantum solutes—have been largely restricted to very dilute electron concentrations. We overcame this limitation by applying soft x-ray photoelectron spectroscopy to characterize excess electrons originating from steadily increasing amounts of alkali metals dissolved in refrigerated liquid ammonia microjets. As concentration rises, a narrow peak at ~2 electron volts, corresponding to vertical photodetachment of localized solvated electrons and dielectrons, transforms continuously into a band with a sharp Fermi edge accomp...
