Things painted with Vantablack (the name comes from Vertically Aligned Nanotube Arrays) look like mini black holes. In photographs, because there are no shadows, it looks as though 2D black shapes have been painted on the photograph’s surface.

TIL about Vantablack – the "world's darkest material”. It absorbs up to 99.965% of visible light that strikes it, measured perpendicular to the material. This is a wrinkled piece of aluminium foil which has been painted with it – the centre is as wrinkled as the foil around it.

Meet the manchineel tree! It’s incredibly toxic: just standing underneath it can cause horrible blisters. Its sap contains phorbal (which is water soluble, making this a bad place to stand in a rainstorm) which causes a strong inflammatory response and promotes tumour formation.

The manchineel tree is native to southern North America to northern South America.

Its fruit look like small apples, hence one Spanish name is manzanilla de la muerte, "little apple of death” 💀

This month’s piece of short fiction from me is:

I hope you enjoy it 🌙

The Faint Sounds of Music and Life in the Distance

the fiction phial

perennial: lasting for a long time, or (plants) having a lifecycle of 2+ years

perineal: relating to the area between the anus and genitals

Let the ‘nn’ remind you of the 2 years.

Unless you’re talking to a doctor, you probably mean ‘perennial problem’ 😉

further vs. farther

These both mean ‘more distant’ but, especially in US English, farther implies physical distances, while further is more figurative: yoU should consider this fUrther while you wAlk fArther

And watch out for the easy typo of switching ‘farther’ for ‘father’ 👨🏼

Thyme* for a little proofreading thread of words that are often confused, with some helpful tips for getting it right… 🧵

(*See what I did there? 😉)

And by the way, if you fancy having a little moment, the petition is still there, and so are people’s “reasons for signing”.

He inspired a lot of scientists, over the years 💜

Sign the Petition

Name new element 117 Octarine, in honour of Terry Pratchett's Discworld

Change.org

I like to think Terry Pratchett would’ve been amused 😄

You can still buy the pencil sharpener. Hopefully it’s made of sapient pearwood. Mine’s never moved, though.

Also, yes, octarine is a halogen. Yes, 117 is the perfect number for a DW element. Fight me.

Granny smiled grimly. It was the sort of smile that wolves ran away from. Granny grasped her broomstick purposefully.

‘Million-to-one chances,’ she said, ‘crop up nine times out of ten.’
