Do protons have intrinsic charm? New evidence suggests yes

00:47 Evidence of a proton’s charm

For decades, scientists have debated whether protons have ‘intrinsic charm’, meaning they contain elementary particles known as charm quarks. Now, using machine learning to comb through huge amounts of experimental data, a team have shown evidence that the charm quark can be found within a proton, which may have important ramifications in the search for new physics.

We talk to Paisley Currah, who has written a World View for Nature arguing that these policies are frequently not backed up by data, and that policy affecting trans people’s lives needs to take a more evidence-based approach.World View: To set transgender policy, look to the evidenceWatch our video about research trying to crack the nature of consciousness by dosing volunteers with psychedelic drugs and scanning their brains.Subscribe to Nature Briefing, an unmissable daily round-up of science news, opinion and analysis free in your inbox every weekday.
