3 BritBox shows you should watch in August 2024
The era of streaming has pretty definitive pros and cons. Cable was expensive, but it led to a more linear experience where you know what you subscribed to, and could watch what you wanted only when it was on. Streaming allows for more choice, but wi.....»»
Bacteria encode hidden genes outside their genome; do we?
Since the genetic code was first deciphered in the 1960s, our genes have seemed like an open book. By reading and decoding our chromosomes as linear strings of letters, like sentences in a novel, we can identify the genes in our genome and learn why.....»»
