Similarly, when aphids are raised on plants genetically engineered to emit a compound that warns surrounding aphids of a predator, they become accustomed to the chemical ... Read More
Researchers have confirmed a long-held but unproven hypothesis that mammalian cells are capable of synthesizing RNA by copying RNA molecules directly.
The team used single-molecule sequencing technology, which has detected and quantified novel small RNAs in human cells that represent entirely... Read More
The aim of this study was to explore the relationship between pharmacy size and the likelihood of obtaining antibiotics without medical prescription at a pharmacy. In 2008 in Catalonia, two actors presented three different cases in a randomised sample of pharmacies and asked pharmacists for an a... Read More
