A Small-Molecule Approach Enables RNA Aptamers to Function as Sensors for Reactive Inorganic Targets.

Fluorescent light-up aptamer (FLAP) systems are promising (bio)sensing platforms that are genetically encodable. However, FLAP-mediated detection of each distinct target necessitates either in vitro selection or engineering of nucleic acid sequences. Furthermore, an aptamer that binds an inorganic target or a chemical species with a short lifetime is challenging to realize.

Mesophilic versus thermophilic digestion of sludge in anaerobic membrane bioreactors.

Energy-efficient wastewater treatment plants (WWTPs) utilize systems like high-rate activated sludge (A-stage) system to redirect organics from wastewater are redirected into energy-rich sludge (A-sludge).
