It's raining outside, so obviously Flynn has to come and let me know.

Hi Nori. How have I disappointed you today?

Taking a day off to help get over this stinking cold and upper respiratory tract infection. Flynn feels that chest compressions might help...

She's a snuggly little bug.

Old phone screen died weirdly. Phone was on, but the screen totally blank. Not broken, because rebooting it gave the Google splash screen. Just completely blank in user mode. Anyway, new pixel phone, new camera. Enjoy Flynn and Honey in 50MP HD

Don't mind Honey. She's just sat in her box. Having an existential crisis.

Been a bit lax at cat posting here on BlueSky. Here's a selection of Flynn recently.

Two cats didn't feel like enough cat to fill the house. So I'd like to introduce our newest feline, Flynn.

Some heartbreaking news. Received a phone call from a vet that no-one wants. My beautiful, funny, silly, and feisty cat Tilly had been brought in after being attacked by a dog. Efforts to save her were unsuccessful. Hug your pets folks.

Only shelves and doors left to go. Time for a cider!
The previously empty wardrobe carcasses now have drawers installed. There is still a lot of empty space for shelves.

It's a bank holiday weekend, so obviously I am building flat-pack wardrobes. Mrs okapi for scale.

1.5 micron grating measured earlier today. As you can see there's no issue with resolution here, and we can likely go quite a bit bigger.

The wing in question.
A butterfly wing mounted in a 35mm slide holder. There are two strips of lead tape to demarcate an area of interest and assist in sample alignment. 

Also visible are two rulers, for scale.

In case you were wondering what ultra-small angle X-ray scattering from a butterfly wing looks like. The central peak is the unscattered beam. Satellite peaks are Bragg-like diffraction from the wing structure, giving rise to its green colour.
A plot of intensity Vs scattering angle for X-rays scattered by a butterfly wing. There are several peaks in the plot, which show that colour in a butterfly wing is crafted by its structure, rather than pigment.

A view of our embarrassingly messy kitchen after evicting the tabby. All three of our cats are in this picture. Note how none of them are in the foreground, helping with the eviction.
A kitchen diner. There is a flight of stairs running upward in the middle of the picture, and a breakfast bar to the right. Three cats can be seen. One next to the stairs, one at the top of the stairs, and one hiding on a table at the back right. None of them are helping to get rid of the strange cat...

Cute little guy. Has been in and out several times this evening. My three (3!) cats have all just backed off and watched him stroll around.

Attention everyone. The friendliest cat in the world and the old grumpy cat, who hates her, are sharing a sofa. This is unprecedented.
