Stitched Up


The brain’s processing power easily surpasses the most advanced supercomputer, yet information technology can still help us to understand our nervous systems. Mapping out connections of this developing fruit fly’s nervous system, the sophisticated computer algorithms of a new software called BigStitcher work alongside two microscopy techniques: expansion microscopy, to swell and inflate the tiny tissues under the lens, and light sheet microscopy to take thousands of virtual ‘slices’ through the cells. Each coloured area is a huge 3D image (carrying many gigabytes of data) virtually reassembled into a mosaic ‘map’ of the whole nervous system. The next challenge is interpreting the information – perhaps calling on algorithms again to help follow the snaking paths of each individual nerve cell or neuron – and deciphering clues about common neuronal patterns found in ‘higher’ organisms like humans.

The Tulip in the Swan

Explanation: Framing a bright emission region, this telescopic view looks out across a pretty field of stars along the plane of our Milky Way Galaxy, toward the nebula rich constellation Cygnus the Swan. Popularly called the Tulip Nebula, the reddish glowing cloud of interstellar gas and dust is also found in the 1959 catalog by astronomer Stewart Sharpless as Sh2-101. About 8,000 light-years distant and 70 light-years across the complex and beautiful nebula blossoms near the center of this composite image. Ultraviolet radiation from young energetic O stars at the edge of the Cygnus OB3 association, ionizes the atoms and powers the emission from the Tulip Nebula.
