Scientists are a step closer to “Holy Grail” of turning carbon dioxide into fuel

Scientists have spent decades trying to replicate photosynthesis – the reaction that allows plants to convert carbon dioxide, water and sunshine into the sugar that fuels its growth. If we can work out how to replicate “artificial photosynthesis”, we would essentially be able to easily and cheaply

Human Genome Shaped by Arms Race With Itself

The arms race is between mobile DNA sequences known as “retrotransposons” (a.k.a. “jumping genes”) and the genes that have evolved to control them. The UC Santa Cruz researchers have, for the first time, identified genes in humans that make repressor proteins to shut down specific jumping genes. The researchers also traced the rapid evolution of the repressor genes in the primate lineage.

Their findings, published September 28 in Nature, show that over evolutionary time, primate genomes have undergone repeated episodes in which mutations in jumping genes allowed them to escape repression, which drove the evolution of new repressor genes, and so on. Furthermore, their findings suggest that repressor genes that originally

Our brains can make decisions while we’re sleeping

A new study led by senior research scientist Sid Kouider and PhD student Thomas Andrillon at the Ecole Normale Supérieure de Paris in France has investigated how active our brains a
