The first smallpox vaccination was tested on James Phipps. He was initially given a small dose of cowpox (blue), which was not lethal to humans. Afterwards, he was given a small dose of smallpox (red) and showed no symptoms of infection. Thus, the smallpox vaccination was developed (and variolation became a thing of the past).

(Also pterosaurs, which I just learned about and which are super cool.)


This just in: spiders tune the silk threads of their webs like guitar strings

… and they use the distinct vibrational frequencies to help them locate meals and mates. Hear the full story of these good vibrations, from NPR’s Christopher Joyce, here

That’s called being colour-brave. How cute is this orange midi on a colour block knit?

Light micrograph of a mouse embryo, approximately 10.5 days post-fertilisation. The specimen was stained with a fluorescent marker that highlights the presence of precursor cells to nerve tissue then chemically treated to make it optically transparent.

He transformed the pain of his tormented life into ecstatic beauty. Pain is easy to portray but to use your passion and your pain to portray the ecstasy and joy and the magnificence of our world, no one had ever done it before. Perhaps no one ever will again.

The Incredible Eye

The eye stands as a testament to the effectiveness and magnitude of what can be achieved through natural selection. These extraordinary false-colour SEM images of the human eye were the brainchild of Professor Pietro Motta at the Institute of Human Anatomy of the University La Sapienza in Rome.

Top Left: Surface cells on the iris of the eye. Pigment cells (melanocytes, blue and brown) can be seen here, joined loosely together by connective tissue fibres (white). Smaller macrophage cells dot the surface.

Top Right: Lens of the eye. Lens cells run diagonally (dark green) across this field of view. The transparency of the lens (width 4 millimetres) is due to the absence of nuclei in these cells, and to the crystalline precision of their arrangement.

Centre: The inner surfaces of the iris and adjoining structures in the human eye. At far right (blue) is the edge of the pupil, the hole that allows light into the eye. Coloured mauve is the iris which controls the size of the pupil and therefore how much light will enter. The band of folds down the centre (red) are the ciliary processes.

Bottom left: The surface of the cornea. The matrix- like pattern (seen here) consists of individual flattened transparent cells. This is a stratified squamous epithelium which is 5 cell layers deep. Although full of nerves, there are no blood vessels in the cornea.

Bottom right: The human retina featuring the central fovea, a crater-like depression in the photosensitive layer of the eye. The foveal retina is the area of greatest visual acuity and contains only cone receptor cells. When an eye looks at an object, that part focused on the fovea is the portion most accurately registered by the brain.

Does coffee ice cream violate the Word of Wisdom?




According to a study in the journal Animal Cognition, chimpanzee’s do something that seems altogether arbitrary: ear accoutrements.

“Our observation is quite unique in the sense that nothing seems to be communicated by it,” says study author Edwin van Leeuwen, a primate expert at the Max Planck Institute in The Netherlands.

To figure out if this was really a tradition, and not just chimpanzees sticking grass in their ears at random, van Leeuwen and his colleagues spent a year observing four chimp groups in Chimfunshi Wildlife Orphanage Trust, a sanctuary in Zambia.

There’s no genetic or ecological factors, the scientists believe, that would account for this behavior — only culture.

Chimpanzees putting grass in their ears is like us wearing earrings.

Floral anatomy from artist Camila Carlow’s project Eye Heart Spleen

Carlow on her project:

The most fascinating and intricate of biological structures, yet we rarely pay heed to the organs inside our body. Regardless of whether we fill ourselves with toxins or nourishing food, whether we exercise or not - our organs sustain us, working away effortlessly and unnoticed.

In a similar way, plants flourishing in the urban environment are a testament to nature’s indifference to our goings on. They grow out of the sides of buildings, in brick walls and between the cracks in concrete, despite of the traffic and pollution.
