What the season of fall – and science – teaches us about life and death

I was launched as one; and ended up being trillions of them. The cells composing my body are amazing micro-machines; one hundred of them can fit into the period at the end of this phrase. Regardless of my awareness, each of these teeny tiny units strictly performs its own intricate duties: breathing in oxygen and secreting out carbon dioxide, multiplying by splitting into two, migrating around or idling for a while, and ultimately maturing to lay down the specific type of supporting structure known as matrix. The matrix surrounds the cell and sustains its specific function – like soft matrix for skin and hard matrix for bones or teeth.

A cell even has its own brain or, if you will, control panel: the nucleus. This nucleus contains the instructions for building a cell and an entire individual. This four-letter code, known as DNA and measuring 2 meters long from a single nucleus, dictates every single programmed task the cell performs during its life.

Interestingly, the function of a cell does not end at maturation or when it finishes secreting the matrix. The cell’s function is only complete after its final task which is, amazingly, to die: programmed cell death. The term “programmed” describes the organized, planned and careful dismantling of the cell’s components rather than a sudden unpredictable ruination.

Hereford Cathedral Library. The library was formally established in 1611, but the cathedral’s manuscript collection dates back to the medieval era. It is still a working library, and is notable for its collection of chained books (a common practice in the early modern era), and is the only library of this type to survive with all of the chains, rods and locks still intact. The chained library contains 229 manuscripts, mostly medieval, and the earliest book in the collection, the Hereford Gospels, is from around 780.

VIDEO FROM THE SURFACE OF A COMET

This is truly incredible.

Details:

Remember Rosetta? That comet-chasing European Space Agency (ESA) probe that deployed (and accidentally bounced) its lander Philae on the surface of Comet 67P? This GIF is made up of images Rosetta beamed back to Earth, which have been freely available online for a while. But it took Twitter user landru79 processing and assembling them into this short, looped clip to reveal the drama they contained.
