i walk past this entry way every morning on my lone journey to work. it is as if the owner decided to leave his life forever, simply by chaining the gate closed. the chinese address is stripping off the wall and the mini-trees have patiently awaited their caretaker's non-return. i imagine the once vibrant home sleeps now to its own decline.
one day last week i was walking under a viaduct near our apartment and i came across an altar set upon broken book shelves and consisting of chinese and hindu figurines. the dust settled upon the deities as they looked over the finished incense sticks, which i assume represent prayers that have long since vanished into the unknown. i took this photo with a sepia tint as the antiquity of the idols seemed to suggest they had been listening for a long time.
this was a fun photo to take. as a stem cell and tissue repair scientist, much of my work consists of trying to regenerate bone and stimulate stem cells to start functioning again. i took this image this morning as i was evaluating a histological stain of the epiphyseal growth plate in a rat tibia. to get to this point, i embedded a whole rat bone in resin and then took hair-thin sections to mount on a microscope slide. i then stained the tissue with several different "patinas" to identify the cellular components. the round cells ordered in parallel lines are chondrocytes...in a way they are marching to their death as they become hypertrophic in nature (fat and round). it is here that they give a last effort to lay down cartilage which, upon their death, is mineralized into bone by osteoclasts and osteoblasts. the black color is calcified cartilage or newly formed bone matrix. this production of bone from cartilage is what occurs at your growth plate and in simple terms, lengthens your long bones and allows you to grow. ironically, the process of decay and aging is exactly what leads to growth.
