Oh, Bra-vo.

Scientists think Mercury (the planet) might have a molten core.

Nice work, (literal) Einstein. You mean to say that the planet that's an inch from the sun is all melty inside? Wow. Keep that tax money flowing into the research budget!

Seriously, so you "discovered" that the little rock has a liquid core, which means it has a magnetic field, which is of what use to us, exactly? I've "discovered" that gasoline works faster than lighter fluid to get the grill started. Neither "discovery" is useful to humans.

Did we already establish that Mercury is, like, an inch from the motherfucking sun?
