Two recent studies have found that aging is associated with an increase in transcriptional stress, with one study attributing it to elevated stalling of RNA polymerases and the other to accelerated transcription elongation. Despite appearing contradictory, the authors argue that these findings are not mutually exclusive.
Scientists have developed a DNA-based nano engine that exhibits pulsing movements, similar to a hand grip trainer but on a much smaller scale. The engine is powered by RNA polymerases and nucleotide triphosphates, offering potential applications in advanced nanotechnology. The researchers plan to integrate the engine into complex nanomachines, and their findings have been published in the journal Nature Nanotechnology. The engine's design and operation were aided by computer modeling tools, and it represents a significant advancement in chemically powered DNA nanotechnology motors.
