The first detection of a gravitational wave; the discovery of the first Earth-like exoplanet; the confirmation of the Higgs boson. I’ve been lucky enough to report on all these and more in the last decade. But in terms of significance, the discovery of CRISPR-Cas9 overshadows them all. No other breakthrough this side of the century has greater potential to shape our future. If you’re not familiar with it, CRISPR-Cas9 is a genetic toolkit that lets biologists remove a snippet of DNA, and potentially insert something new. The act of genetic editing itself is not new, but CRISPR-Cas9 is accurate, quick and cheap, and for the last decade or so scientists have been using it to try to solve some of our biggest problems. There are research groups out there using CRISPR…

Head in the stars TELESCOPE LIVE, EL SAUCE OBSERVATORY, CHILE We often make analogies between deep space and the ocean – the word ‘astronaut’ is derived from ‘star sailor’ – but we don’t usually expect to find a marine mammal in the sky. The Dolphin Head Nebula, located 4,530 light-years away, is a bubble of gas and dust that has been blown into this shape by the interstellar winds of the turbulent, dying star in the centre of the image. It was imaged using data from Chile’s Telescope Live. “We can track what’s happening in distant nebulae by looking for light signatures. When a gas gets heated, it becomes ionised – meaning an electron gets knocked off the atom – and emits light with a specific colour or wavelength known as a spectral line,”…

This is not very helpful except as a rough guide, and even then you would need to have an atlas or relevant map with you to complete the comparison. There are standard units of area, such as the acre and the hectare, but how many of us can relate to them? The same applies to the square metre, square kilometre, square…
