Aquaponics treatment system inspired by sewage plants grows tastier crops and keeps fish healthy

Frontiers

By Tayyibah Aziz, science writer. Image: josefkubes/Shutterstock. A novel fish solids treatment system inspired by wastewater and sewage plant systems has been shown to be an effective treatment in aquaculture systems to boost nutrients available for hydroponic plant cultivation in a manner similarly efficient to commercial fertilizers. Researchers demonstrated that the system developed could improve nutrient remineralization while removing excess nitrogen and carbon from the system, creating a

Exotic quantum state could make smallest-ever laser

Physics World

Physicists have taken a step towards realizing the smallest-ever solid-state laser by generating an exotic quantum state known as a Bose-Einstein condensate (BEC) in quasiparticles consisting of both matter and light. Although the effect has so far only been observed at ultracold temperatures in atomically thin crystals of molybdenum diselenide (MoSe 2 ), it might also be produced at room temperature in other materials.
