Argentinosaurus skeleton (PLoS ONE) by William Irvin Sellers, Lee Margetts, Rodolfo Aníbal Coria, Phillip Lars Manning - http://www.ploscollections.org/article/info:doi/10.1371/journal.pone.0078733;jsessionid=441A913F8D576BBA46BF0960D01599FD. Creative Com

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.

As you probably heard, New Horizons was closest to Pluto in July of this year, in what's being called the Pluto Flyby. 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.

Weighing in at up to 13 tons...and over 12 metres long...It's jaws are full of serrated, sharp teeth...It's Giganotosaurus, the giant of Argentina!

bald faced hornet, wasp nest

The wasp nest we found was only the size of a grapefruit, so I blasted it to smithereens with my garden hose. Thrilling as that was, I later suffered science remorse from not more carefully studying this beautiful thing of nature. Hence this post.
