8+ hour, 7+ min ago (615+ words) A bacterial enzyme called universal PPK2 may simplify and lower the cost of RNA synthesis. Inside our cells, DNA'the blueprint of life'and RNA, which supports cellular functions based on that blueprint, are constantly being produced. Both DNA and RNA are made…...
Analysing The Sample Preparation Process In Meteorites And Its Impact On The Pretreatment Of Returned Samples To Earth
7+ hour, 37+ min ago (126+ words) The study of meteorites is important for planetary sciences because, among other things, it can provide information about the geochemical composition of their celestial body of origin. Often, subsample preparation is required to investigate the internal regions of these meteorites....
Thermal Segregation and Reddening in Europa's Double Ridges
7+ hour, 40+ min ago (180+ words) Europa's double ridges often display lower albedo and redder color than their surroundings. Their unique topography may cause sublimation-driven darkening due to illumination and self-heating, a process known as thermal segregation. Incorporating a simple exosphere model and assuming an initial…...
