Australian dragon study reveals surprising link between motor systems control and sleep rhythms
Sleep is one of the most mysterious, yet ubiquitous components of our biology. It has been described in all major groups of animals, including worms, jellyfish, insects or cephalopods, and in all vertebrates, from fish to humans. Common characteristi.....»»
Locally optimized urban form can reduce carbon dioxide emissions
Research suggests that urban areas could reduce their carbon dioxide (CO2) emissions by optimizing their urban form. However, the relationship between urban form and emissions is highly context-dependent and generalizations cannot be made......»»
Biologists discover how plants evolved multiple ways to override genetic instructions
Biologists at Washington University in St. Louis have discovered the origin of a curious duplication that gives plants multiple ways to override instructions that are coded into their DNA. This research could help scientists exploit a plant's existin.....»»
