Engineered Bacteria Connected to Microelectronics

Science Advances – Interfacing gene circuits with microelectronics through engineered population dynamics Researchers interfaced synthetic biology with microelectronics through engineered population dynamics that regulate the accumulation of charged metabolites. They demonstrate electrical detection of the bacterial response to heavy metals via a population control circuit. They then implement this approach to a synchronized genetic oscillator …

29% More Energy Efficient Refrigeration With Multi-Walled Carbon Nanotubes

Power consumption of a home refrigerator can be cut by 29% while improving cooling capacity. Researchers replaced widely-used, but environmentally unfriendly, R134a refrigerant with the more energy-efficient R600a. They dosed R600a with multi-walled carbon nanotube (MWCNT) nanoparticles. A more energy-efficient refrigerant can result in much lower electricity bills. For vulnerable households, energy security can be …
