The Living Clocks – Are Humans and Living Organisms Synchronizing Life?

The brain can read these patterns and learn them. In this way, we can time music or specific tasks to be performed, for example, one second after a signal. Even though not all the clock mechanisms in humans are known, biological clocks share a property with all human-built and non-living clocks: they are limited by quantum mechanics. Even the simple pendulum is limited by quantum theory.

Three scientists have won the 2020 Nobel prize in physics for their work on black hole formation and the discovery of a supermassive black hole at the centre of our galaxy.

Are aliens hiding in plain sight?

Several missions this year are seeking out life on the red planet. But would we recognize extraterrestrials if we found them?

Discovery has major implications for hunt for alien life on the red planet as it means any evidence is likely to be buried deep underground

Black holes may merge with light of a trillion suns, scientists say

When black holes collide, the ensuing cosmic drama was assumed to play out under the cloak of darkness, given that both objects are invisible. But now astronomers believe they have made the first optical observations of such a merger, marked by a blaze of light a trillion times brighter than the sun.

Getting to the bottom of the Higgs boson

In high-energy particle collisions we study the smallest known constituents of matter. According to our best knowledge of physics, these constituents have mass only because of the way they interact with a unique quantity which permeates all of space. This quantity, like practically everything else in the strange world of the very small, is a quantum field.
