'X-Shape' Not True Picture of Chromosome Structure
A new method for visualising chromosomes is painting a truer picture of their shape, which is rarely like the X-shaped blob of DNA most of us are familiar with. Scientists at the BBSRC-funded Babraham Institute, working with the University of Cambridge and the Weizmann Institute, have produced beautiful 3D models that more accurately show their complex shape and the way DNA within them folds up.

Tibetan ritual skull with elaborate silver work and garuda on the forehead.
Probably the last time I’ll illustrate my research species any time soon. I’ve meant to illustrate this for a while; there aren’t many images that show the difference between the genders of woodlice. It’s quite simple once you know what you’re looking for though!
Murcian MetalmorphosisThis skull’s structure is cast from a real human head and made of hard, unbreakable plastic. It has been “gilt” (the techniques for applying fine Gold leaf) with multiple layers of EPL genuine 24 Karats gold leaf. The skull was completely disarticulated into 22 pieces for the gilding process and reassembled on a stand with movable joints that allows for the bones to be studied as a whole, or as individual parts. The methodology by which the skull was assembled was used by French Anatomist, Claude Beauchene, in the mid-1800s. It took over 1000 hours of meticulous work to assemble this skull.

Mia Jane-Harris creates absolutely stunning close-up photographs of medical specimens of human cadavers in her series “Your Corpse is Beautiful” and shows us just how beautiful death can be.
A bit of a detour into neuroscience today with a look at the chemical structures of some of the major neurotransmitters in the brain. Inspired in part by this post on the chemicals related to various emotions.
