Should you?

Lots of people think so. Urine has found its way into the mouths of many people over the years, from TV survivalist Bear Grylls to legendary, reclusive author J.D. Salinger.

Besides the terrifying and awesome shapes of dinosaurs, there is one thing that has amazed scientists and the general public since their discovery: their size.

The slime mould, Dictyostelium discoideum

Experimental biologists love to work with slime mould even if it looks like dog barf. They’re so loveable because they share many genes and protein components with mammalian cells, they can exhibit similar behaviours and are much easier to grow in the lab. To make some slime, you simply harvest some spores into a dish filled with a simple sugary broth, allow the population to grow for a few days and—boom!—time to experiment.

New Horizons came within about 12, 800 kilometres of Pluto, which is pretty darn close considering Pluto is 5.87 billion kilometres from our Sun. The proximity to Pluto has resulted in some close-up photographs that are even better than the Hubble space telescope’s.
