Where did the antimatter go? Neutrinos shed promising new light
We live in a world of matter – because matter overtook antimatter, though they were both created in equal amounts by the Big Bang when our universe began.
As featured on the cover of Nature on 16 April 2020, neutrinos and the associated…

Origins of Earth’s magnetic field remain a mystery
Microscopic minerals excavated from an ancient outcrop of Jack Hills, in Western Australia, have been the subject of intense geological study, as they seem to bear traces of the Earth’s magnetic field reaching as far back as 4.2 billion years…

Does relativity lie at the source of quantum exoticism?
Since its beginnings, quantum mechanics hasn’t ceased to amaze us with its peculiarity, so difficult to understand.
Why does one particle seem to pass through two slits simultaneously? Why instead of specific predictions can we only talk about…
