Nurture trumps nature in determining severity of PTSD symptoms

Researchers at Yale and elsewhere previously identified a host of genetic risk factors that help explain why some veterans are especially susceptible to the debilitating symptoms of post-traumatic stress disorder (PTSD). A new Yale-led study published in the journal Biological Psychiatry has now identified a social factor that can mitigate these genetic risks: the ability to […]

Computational modelling explains why blues and greens are brightest colours in nature

Researchers have shown why intense, pure red colours in nature are mainly produced by pigments, instead of the structural colour that produces bright blue and green hues. The researchers, from the University of Cambridge, used a numerical experiment to determine the limits of matt structural colour – a phenomenon which is responsible for some of […]
