When you are a kid at home, you wanna be something, but you don’t know what. You are at the pro-something stage of your life. You could be a pro-science or a pro-arts.
Similarly, in the bone marrow, pro T cells know they wanna be a T cell but they don’t know which one. Pro T cells are…
Pages from my ‘Levels of Complexity’ project, in which I wanted to explore ways in which I could communicate biology and science-based information in a more accessible illustrative style. I hoped to inspire some amount of awe at just how much is going on ‘beneath the surface,’ such as cells, tissues, organs, processes, etc within our bodies and our environment.
Beware of The Blob! In this talk from TEDxToulouse, biologist Audrey Dussutour uncovers the mystery of myxomycota — a.k.a. le blob — the fascinating blob organism whose unicellular structure betrays a surprising personality.
daniel stoupin, a doctoral candidate in marine biology at the university of queensland, has photographed a variety of coral species using full spectrum light to reveal fluorescent pigments that would otherwise be invisible to the naked eye. each piece (click pic for name) is from the great barrier reef. given the complexity of the techniques used, which involve time-lapse and stereoscopic and focus stacked photography, the images take up to ten hours to produce in the lab.
Wow. I thought these were computer-generated protein models or something at first, but these are brilliantly fluorescing corals!!
What might be seeing these stunning fluorescent displays? Coral aren’t known to have any photo-sensitivity (at least past the larval stage), so the obvious candidates are fish, whose eyes would be sensitive to the emitted fluorescent wavelengths.
Do fish like that exist? Earlier this year, researchers at the American Museum of Natural History were photographing their own corals’ fluorescence when they accidentally noticed one of their eels was fluorescing too. No one had noticed because the fluorescence is usually masked in the presence of broad visible light as seen by us land-lubbers.
It turns out that fluorescence in fish is surprisingly common. Water filters out long and medium wavelength light (reds and yellows) as it gets deeper, which is why it’s blue. To compensate for this limited spectral availability, fish have turned to fluorescence as a way to expand the wavelengths of communication and camouflage in their normally azure-monochrome world.
Spencer Lowell has photographed sites of nearly every form of energy harvesting in the United States, from the Tennessee Valley Authority’s Norris Dam to oil refineries in eastern Texas. Take a look at photos from his latest project, “Power Hungry,” which intently scrutinizes how energy production alters landscapes: http://nyr.kr/MwXqiy

Paul Kooiker - Utrechtse Krop (published 1999)
"In the early days of medical photography clinical standards had yet to be formulated for photographic images. Consequently, photographs of that time are more poignant and beautiful than they are scientific.
Light, space and patients` complete submission to doctors and photographers evoke feelings of compassion, surprise, embarrassment and amusement rather than disgust or scientific curiosity.
Utrechtse Krop focuses on the meaning and significance of photobooks concerning health care environments. Intimate stories on matters of life, sickness, death and personal loss are observed and experienced by consecutive generations of photographers working in the documentary tradition.”

The Morphology of Human Blood Cells (1956)
Dorothy Sturm’s beautiful watercolors are difficult to distinguish from an actual microphotograph (except perhaps they are clearer and more detailed than a micrograph, and certainly superior to images from the 1950’s).
Sturm’s watercolor on paper illustrations, drawn directly from Wright-stained smears prepared by [microbiologists], depicted normal, pathological and infectious hematology with a clarity, detail and beauty that photomicrography of the 1950’s simply couldn’t approach. JAMA, in a review of the first edition, even called her work “of exceptional quality.”
 This table showing hematopoiesis (as it was understood in 1956) was the frontispiece of the first edition of Diggs’ The Morphology of Human Blood Cells. Here’s the key to this illustration.
