mechanised birdsong

A mechanical singing bird mechanism. Made around 120 years ago in Paris, probably by Bontems. In the film I hope you can identify all the major parts and see them working together to make the sound. The mechanism was in a rusted and seized state and has been restored. Surpisingly the bellows are in good original condition. See our channel for more, much more.

If this is for real, it’s very impressive! Actually if it were not real it would be impressive too. See more at the house of automata. (via sciencedump)

the littlest clean-up team

Watch a time-lapse video showing the Museum’s smallest workers, flesh-eating beetles, preparing the skeletons of a great green macaw, tawny owl and mountain peacock-pheasant for our collections. Chemical preparation of skeletons can cause damage to the bones so a special beetle species, Dermestes haemarrhoidalis, is used to strip off the flesh while leaving the bones and collagen untouched.

The Natural History Museum is using a species of flesh-eating beetles to clean-up skeletons of bird specimens. They were kind enough to upload a video for the curious.

return of the t-cell


Here’s a BBC documentary about the human cell and its relationship over billions of years with the virus cell.

It takes a nice, broad perspective and presents the story with impressive visuals. Quite impressed as I am, I didn’t like the incredibly tedious camera work for the in-between segments, and the drone of David Tennant’s narration throughout the entire film. You can’t have it all.

Update: Pity the video has been taken down. It was called Secret Universe: The Hidden Life of the Cell.

in aristotelian wars the combatants simply fight forever

He understands, as Darwin would, that there is a war of nature. But, where in Darwinian wars some species flourish while others go extinct, in Aristotelian wars the combatants simply fight forever.

A documentary exploring Aristotle’s biological investigations and comparing his understanding to our current knowledge.

coalescence cascades

The other day I was wondering… Why does rain not accumulate (‘coalesce’) in the sky, given the distance it falls, to form deadly sheets or lakes of rainwater that could fall in one place as one large mass? I found the explanation that there is a maximum size of droplet that is reached before the droplet begins to break apart again in freefall.

Picture a huge room full of tiny droplets milling around. If one droplet bumps into another droplet, the bigger droplet will “eat” the smaller droplet. This new bigger droplet will bump into other smaller droplets and become even bigger–this is called coalescence. Soon the droplet is so heavy that the cloud (or the room) can no longer hold it up and it starts falling. As it falls it eats up even more droplets. We can call the growing droplet a raindrop as soon as it reaches the size of 0.5mm in diameter or bigger. If it gets any larger than 4 millimeters, however, it will usually split into two separate drops.

On the topic of water coalescence I coincidentally discovered this uncanny video that shows a mind-boggling dance that occurs when a drop of water meets another body of water. The drop only becomes assimilated after a strange interaction that happens too quickly for us to see without high-speed cameras.
