Starship size comparisons.
You'll understand my current interest in any seasonally relevent article about losing weight. This one, by Dr Karl about where fat goes when it goes away, is gross but fascinating:
When your body burns fat, it has to inhale lots of oxygen from the air (78 molecules of oxygen to burn one molecule of triglyceride).
Suppose you want to lose 10 kilograms of fat. That means you're going to have to add 29 kilograms of oxygen. That's a lot of breathing, and huffing and puffing. And to finish the process, you're going to get rid of 28 kilograms of carbon dioxide and 11 kilograms of water.
And how are you going to get rid of this 39 kilograms of carbon dioxide and water? Overwhelmingly, by breathing them out.
You might lose a tiny amount of this water as sweat or urine. But the vast majority of those atoms that originally made up triglyceride molecules exit your mouth and nose as carbon dioxide and water. However, you have to do a lot of breathing – each breath removes only 33 milligrams of carbon dioxide.
This means that your main excretory organ is your lungs.
My lungs are gonna be working overtime through January. I didn't pack on my normal five kilo christmas pudding, but the tummy eel is looking undeniably well fed.

The last ep of the Clockwise podcast (four technology topics, four contributors, thirty minutes) featured listener questions for its last episode this year, and I am ridiculously excited to announce they used mine:
"Apple, Goolge and Microsoft all release neural nanonic wetware. The Internet in your head! Which one are you gonna buy?"
I work in media. I shouldn't get excited by this. But I do. I really, really do.
It's the last question, so scrub to the final third if you must. But the whole show is always worth a listen. I especially enjoy it when driving kids to school. The shorter length makes it a complete experience.

This story in the Herald is pretty cool. But it would have been cooler if the dark matter sucked the dinosaurs off the planet into a passing singularity. Professor Randall's hypothesis is kind of banal by comparison.
In her book, Dark Matter and the Dinosaurs, acclaimed Harvard theoretical physicist Lisa Randall outlines a complex – and radical theory – that goes something like this: about 66 million years ago, gravitational perturbations caused by a thin pancake-shaped disc of dark matter in the Milky Way galaxy dislodged icy comets in the Oort cloud at the very edge of the known solar system, resulting in the fiery meteoroid that eventually crash-landed in the Yucatan, leading to the mass extinction of more than 75 per cent of life on the planet in the process.

Can't recall where I found this fellow but I've been meaning to show him off for a while. Andreas Mogensen, Denmark's first astronaut took twenty Lego spacemen up to the ISS and sent one out on a space walk. As his little plastic crewmate floated past the window he got this shot.

A couple of years ago I stared using an email app called Mailbox. It was simple, elegant, powerful, intuitive, all the things Apple’s Mail.app wasn’t and isn’t. The feature I really liked was the swipe. Mailbox were the guys who came up with the idea of triaging your inbox by swiping left or right, Tinder style.
For a couple of years I didn’t bother opening Apple’s baked in mail app at all.
Now Mailbox is dead. Acquired by Dropbox, they were left to rot and now they’re being buried. This makes me sad, and perhaps even a little unhinged, because this very morning I have installed Outlook on all my iThings and my desktop. The Verge tagged it as the best mail client for Apple users, which would be weird, expect Satya Nadella has been red hot on providing Office as a service for both iOS and Mac (mostly for iOS, because of the big spending demographic on offer).
Word on the iPad is simple, elegant, powerful… well, yeah, you get it. I don’t have any Windows kit in the house but I hear the iOS versions of Word in particular are nicer than the native flavour. And, since I already have an Office 365 subscription for editing manuscripts in Word, I figured I’d just go with the Verge’s advice and let a little bit more of Satan’s Own software suite onto my shiny preciousesss…
Just the tip. Promise
