“#Toward principles of gene regulation in multicellular systems” Credit: CC0 Public Domain A team of quantitative biology researchers from Northwestern University have uncovered new insights into the impact of stochasticity in gene expression, offering new evolutionary clues into organismal design principles in the face of physical constraints. In cells, genes are expressed through transcription, a…
“#Japan begins charging for plastic bags” Shops, including Japan’s ubiquitous convenience stores, can decide how much to charge customers for the bags Retailers in Japan began charging for plastic bags on Wednesday, a move aimed at curbing Japanese consumers’ love for packaging and finally bringing the country in line with other major economies. Shops including…
