The discovery of 5,000-year-old bacteria – that was until recently trapped in ice – could help or hinder humanity’s battle against infection

This school-bus-sized predator was so unusual that scientists didn't recognise it at first

If you got eaten by a snake, it could take a whole month to digest you... but it would at least leave your hair

Wakey-wakey! Find the sweet spot for a coffee shot and science says the benefits are grande.

There’s a growing school of thought in neuroscience that argues every action is predetermined, or at least highly probable. That my actions are just the sum of biological and environmental interactions outside of my control. Roughly speaking, the idea is that electricity pinballs between my ears, bouncing around the memories and concepts I hold there without my being conscious of it, before arriving at a series of outputs that prime my fingers to type this very sentence. And only then, do I become aware of ‘deciding’ what I want to write. Action precedes thought, in other words. This isn’t just a theory – there’s evidence to back it up. It seems that, in certain scenarios, neurons controlling your arms and fingers are ready to fire before those involved in conscious thought are fully active. I’m skipping over a mountain of philosophy and psychology, but you get the picture. If, like me, this idea leaves you feeling a little uneasy, maybe this will help. Neuroscience has gotten incredibly close to the minutiae of the brain in the last two decades, but it hasn’t yet wrestled with the big picture. The discipline can tie different actions to different parts of the brain, but it can’t explain why it feels good to spontaneously dip your hand in a cold, clear river, for example. My point is, neuroscience is uncovering all kinds of fascinating oddities about how the brain works, but we’re a long way away from a true understanding of how this adds up. Does free will actually exist?

Social fear isn’t just psychological. New research is uncovering its biological roots – and how to reset them.
