For the first time, scientists have observed a collection of particles, also known as a quasiparticle, that's massless when moving one direction but has mass in the other direction. The quasiparticle, called a semi-Dirac fermion, was first theorized 16 years ago, but was only recently spotted inside a crystal of semi-metal material called ZrSiS.

Yes, utterly stranger than fiction.
Until this report, you couldn't use the notion in Sci-Fi for being 'Too Handwavium'
Yes, my wits hurt just trying to think about it...

Just donated my beloved wife(RIP)'s two violas, tenor recorder and a hefty box of formal scores, 'fun compilations', 'seasonal sing-alongs' etc etc to a SIL as one of her grand-children is rapidly evincing *serious* musical talent. Lest budding maestro's young sib is jealous of his clever sis' bounty, I put a £_10 in his card...
