Special report: Living in denial | New Scientist
Special report: Living in denial From climate change to vaccines, evolution to flu, denialists are on the march. Why are so many people refusing to accept what the evidence is telling them? In this special feature we look at the phenomenon in depth. What is denial? What attracts people to it? How does it start, and how does it spread? And finally, how should we respond to it?
Gene change in cannibals reveals evolution in action
Fore tribe women in 1957 suffering from kuru. The women are showing upper limb postures adopted to prevent postural tremors. From Philosophical Transactions of the Royal Society B (Image: 2008 The Royal Society) It’s a snapshot of human evolution in progress. A genetic mutation protecting against kuru – a brain disease passed on by eating human brains – only emerged and spread in the last 200 year
Bacteria make major evolutionary shift in the lab
A major evolutionary innovation has unfurled right in front of researchers’ eyes. It’s the first time evolution has been caught in the act of making such a rare and complex new trait. And because the species in question is a bacterium, scientists have been able to replay history to show how this evolutionary novelty grew from the accumulation of unpredictable, chance events. Twenty years ago, evol
Altruism needs selfish genes to evolve after all
It’s a problem that has been debated ever since Darwin: how have hundreds of species of insects and other animals evolved altruistic helpers that give up their own reproduction for the sake of others? Recently, the orthodox explanation – that they favour their own genes indirectly by helping their kin – has been fiercely challenged by Edward O Wilson, one of the most prominent evolutionary biologi
New Scientist Short Sharp Science Blog: Bring on the dancing girl
OK, hands up if you can make her change direction. No? Only clockwise? How about making her stop? This strangely compelling, animated silhouette of a woman spinning gracefully has been doing the rounds via email lately and the New Scientist office was one of many that spent a guiltily non-productive afternoon staring at her. Why? Because some people see her spinning clockwise, some see her moving
