Plot twist: How giving old graveyards new life as parks can improve our cities
Old graveyards are a forgotten land asset that can find new life as urban parks in crowded cities. As the density of our cities increases, efficient use of urban land becomes paramount. In particular, land for urban parks becomes more important and h.....»»
Glitch in protein synthesis could affect tumor growth
During protein synthesis, or translation, genetic information transcribed in the cell's mRNA directs the stringing together of amino acids—the building blocks of proteins. As the translation machinery carouses along the string of nucleotides that m.....»»
