Horse evolution visualized Seriously, how cute would a pet mesohippus be? Earlier this year, the genome of a 700,000 year-old horse was sequenced from DNA extracted out of a bone fragment frozen in permafrost. It rewrote much of what we know about the evolution of Mr. Ed et al.

Myelinated nerves. A section through myelinated nerve fibres and Schwann cells.Myelin (green) is an insulating fatty layer that surrounds the nerve fibre (axon, black), increasing the speed at which nerve impulses travel.

The retina contains five classes of neurons: photoreceptors (purple), horizontal cells (yellow), bipolar neurons (green), amacrine cells (pink and blue), and ganglion cells (pink and blue). In this cross section of an adult mouse retina, only a subset of bipolar cells, “the ON bipolar cells” are visible by their expression of GFP (green). The pink and blue speckled striations at the bottom of the image mark the fiber layer, which contains the ganglion cell axons that will form the optic…

Capillaries in lung. Capillaries surround the individual alveoli ,air sacs, allowing for the exchange of oxygen and carbon dioxide between the capillaries and the alveoli. Mammal **On Page Credit Required** - SEM X415 3.5" X 6.5"

Human chromosomes, SEMs. Top center (pink and blue) are the X and Y chromosomes. 23 inherited from mother, 23 from father to make full complement. So much information encoded here.

8 Ways to Maximize Telomere Length and Increase Life Expectancy ~ Article wasn't that helpful. But I'm pinning this as a reminder to research telomeres. Article was okay, fine, just not earth shattering.
