Stress Protein Evolved Early

Stress protein evolved early according to a report in Science News 21 May 2005. The “fight or flight” response to stress in vertebrates (including humans) involves a hormone named corticotrophin-releasing hormone (CRH) and a protein named CRH binding protein. Mark Huising of Wageningen University and Gert Flick of Radboud University in the Netherlands, have found […]

Spring Winged Aircraft

Spring winged aircraft described in ScienceNOW, 19 January 2005. Insects use two layers of muscle to flap their wings – as each layer contracts it stretches the other, which then contracts whilst the other layer relaxes and gets stretched ready for the next cycle. This process occurs too quickly to be controlled by nerve impulses, […]
