Sometimes I wonder who needs the padded cell more. Him or us.
Shot in my study just prior to the Cupboard Love photograph so no lighting or seamless background. The cutout was a little more tricky than normal as a bookshelf was behind his head so the refine edge tool wasn't too effective. I resorted to a technique that Aaron Nace (Phlearn) teaches where you draw in the hairs on the mask by scribbling near the edge with a very fine brush. Seemed to work.
I decided to move away from my preferred warm tones for this image as I thought the blue suited it better. I still couldn't resist throwing a bit of subtle warmth into the highlights though, if only to make him look a little less like a smurf.
I hope everyone is having a great Bank Holiday weekend.
Osteochondroretricular stem cells (red) are a newly identified type of bone stem cell that appears to be vital to skeletal development. Research on these stem cells may lead to treatments for osteoarthritis, osteoporosis and fractures.

Microtubules (red) and actin filaments provide structural support for this human HeLa cell (nucleus in blue). Molecular motors like Myosin 15 (green), a protein essential for normal hearing in people, use actin filaments as railroad tracks to transport cargo within the cell.

A breast cancer cell, photographed by a scanning electron microscope, which produces a 3-dimensional images. The overall shape of the cell's surface at a very high magnification. Cancer cells are best identified by internal details, but research with a scanning electron microscope can show how cells respond in changing environments and can show mapping distribution of binding sites of hormones and other biological molecules.

The staircases in each building group are enclosed by a giant object that represents the decade. In the 90s buildings, it's a giant cell phone.
This image shows a longitudinal section of a root tip of Maize (Zea mays). To the left of the image, the large, loosely packed cells of the root cap can be seen. These cells protect the actively dividing meristematic tissue as the root grows down through the soil. This meristematic tissue is located just to the right of the root cap, where the cells are small and undifferentiated. If you follow the lines of cells towards the right, you can see that they increase in length in the zone of elongation. To the right of this zone, the cells become further differentiated, eventually assuming the mature structure related to their function.
This image is taken from a slide in the Botanical slide collection, Department of Plant Sciences, Cambridge. The specimen had been stained with Safranin O and Fast Green and was captured using a confocal microscope. These stains are often used together as general stains on plant material prepared for light microscopy and between them they stain many subcellular structures. The resulting colours are due to a combination of the stains and fluorescent colours in the cells.
The length of the section is approximately 300 µm.

Why do you need a camera when you have your cell phone? Never befor I saw so many people shooting pictures with cell phone cameras.
Is that IN?
This is the view down cell block seven at the Eastern State Penitentiary in Philadelphia, Pennsylvania. I encourage everyone to take the tour if you have time while you're visiting Philadelphia. A really amazing building with an amazing history that not too many people know about.
According to the Penitentiary website: In May 1833, architect John Haviland created a new model for Cell Block Seven, one with several advantages over earlier cell blocks at the site. The most noticeable difference between Cell Block Seven and the previous two story cell blocks – Four, Five & Six – is the 30 foot barrel vault ceiling. In addition, Haviland set the catwalks back so they did not hang over the first floor. This made the block brighter and contributed to the Cathedral - like atmosphere. When Cell Block Seven was finished in 1836, it marked the completion of the original construction.
Without an extreme wide angle lens, the only way to fit this vast array of pipework, hydraulics and gantries into one picture was to stitch shot together. This is a 2 shot panorama of cell 4 in all its glory. It is fairly impossible to convey the size of this place through photographs alone; suffice to say, everything about the site is BIG. By far the best explore I've done yet, and certainly the most tense for parts of it!
Human embryonic stem cells were differentiated into cells of the pancreas (blue). These cells give rise to insulin-producing cells (red). When implanted into mice, the stem cell-derived pancreatic cells effectively replace the insulin lost in type 1 diabetes. ViaCyte has several CIRM grants to develop a stem cell-based therapy for diabetes.

Both cell and phone found in Alcatraz. It was pinker than I imagined in there.
Superb exhibition "Chiharu Shiota - The Soul Trembles" at the Grand Palais in Paris.
Cell (2020)
Chiharu Shiota's inspiration often emerges from a personal experience or emotion that she expands into universal human concerns. The questioning of life and death appears very high in her work.
"Cell" evokes cells multiplying as they can be observed under a microscope. She links this image, greatly enlarged with elements normally invisible to the naked eye, to a tiny character. The millions of cells in the organism represent a complex universe, and the human takes his place between this small world essential for life and that of the cosmos which is even larger.
Chiharu Shiota expresses the idea that each element from the smallest to the largest is connected by the same vital energy that circulates and transforms, but which does not disappear: "Passing from life to death is not an extinction, but a process of dissolution into something larger. If this is the case, then there is no longer any need to fear death."
Life and death belong to the same dimension according to her.

Superbe exposition "Chiharu Shiota - Les frémissements de l'âme" au Grand Palais à Paris.
Cellule (2020)
L'inspiration de Chiharu Shiota émerge souvent d'une expérience ou d'une émotion personelle qu'elle élargit en préoccupations humaines universelles. Le questionnement sur la vie et la mort apparaît très top dans son travail.
"Cellule" évoque des cellules en train de se multiplier comme on peut les observer au microscope. Elle relie cette image, fortement agrandie d'éléments normalement invisibles à l'oeil nu, à un personnage minuscule. Les millions de cellules dans l'organisme représentent un univers complexe, et l'humain prend sa place entre ce petit monde essentiel pour la vie et celui du cosmos qui est encore plus grand.
Chiharu Shiota exprime l'idée que chaque élément du plus petit au plus grand est relié par la m^me énergie vitale qui circule et se transforme, mais qui ne disparaît pas: "Passer de la vie à la mort n'est pas une extinction, mais un processus de dissolution dans quelque chose de plus vaste. Si tel est le cas, alors il n'y a plus lieu de craindre la mort."
la vie et la mort appartiennent à la même dimension selon elle.

Cancer is unchecked cell growth. Mutations in genes can cause cancer by accelerating cell division rates or inhibiting normal controls on the system, such as cell cycle arrest or programmed cell death. As a mass of cancerous cells grows, it can develop into a tumor.
Two shot vertorama with the TS-E. Had to crop out a lot because I was low to the ground and was unable to level my tripod. I need to get one of those hotshoe bubble levels!
The ability of cancer cells to move and spread depends on actin-rich core structures such as the podosomes (yellow) shown here in melanoma cells. Cell nuclei (blue), actin (red), and an actin regulator (green) are also shown.

Today I was given access to the cells in Richmond Castle. Originally built in the 19thC to house prisoners, they were most famously (infamously)? used to house Conscientious Objectors during WWI (1914-1918). The cells are not very big, probably about 10' long by 7' wide. There's no heating and the prisoners were guarded by serving military that probably had no sympathy whatsoever for the inmates. The inmates, along with their guards and other users of the building left their mark through graffiti. Somebody has actually counted and there are 2,300 examples of graffiti dating back to the mid 19thC. The cells are not open to the public, so I feel privileged to have been given access and allowed to take pictures. I hope to visit again soon.

Today's Flickr Group Roulette theme is "Guilty Pleasures" so I decided to do a little sharing of the TMI variety.
I, like many men, don't feel like I necessarily need to rush through the process of going "number 2". Sure, if I'm in a hurry or have other stuff to do, I'll get my bizness done quickly. But sometimes a man wants to just relax on the porcelain throne for a bit while nature takes its course. Some guys read the newspaper or magazines, I break out my cell phone and play Sudoku.
Also did this widescreen to sneak in before the deadline for the 365 Men's Club theme of the week!
We were invited to Construct3D, a conference on digital fabrication and education, to make an art piece that could be collaboratively created with attendees. For that, we created Puzzle Cell Complex, a 5 foot gyroid surface assembled out of 69 unique flat panels which fit in a suitcase and can be put together from a simple page of instructions. The three-dimensional form is encoded in the shape of the panels and how they connect. The piece features three layers of pattern.
