Seriously. Look at those front feet! What a guy he is! Handsome, fuzzy, sometimes full of purrs, sometimes out of sorts for having to share with our senior adult cat, or the new kittens. Mellow out, maan. When he does, he's a complete treasure. We're working it.

The image depicts the interaction between a brain cell known as astrocyte (shown in blue) and a synthetic material (shown in green) that mimics the extracellular environment. The material made of peptides and DNA forms fibrous bundles (highlighted in yellow) that are similar to the ones present in the spinal cord when an injury occurs. The architecture of the synthetic matrix triggers the cell to become reactive as evident by its morphology.

Big Island of Hawaii, north-east corner, near Waimea. When you stop to look at a map, there are far more than the 3 "big" volcanos on Big Island. I'm tempted to say this is a very 3D "meadow" but I suspect the actual grass we see was deliberately introduced for cattle farming, so not wild. But it is grass...

Mural in the Life Sciences Building
I like the rat with the big brain, upper right. Enlarge, for greater definition.
I have passed this building on my morning walk many times without ever trying to enter. (Many of the campus buildings are closed except to those with a key.) Today I realized that this one is open, and I went in for a short walk around. This mural is in the entry lobby.

Here is Mr. Dill sitting on the spare bed in the office, beautiful to look at, with his white back feet all tucked away and his beautiful black fur setting off his white front toes, ruff and lower jaw. He's very easy on the eyes, and has a very intense expression. Also sleek and silky and very nice to pet.
Now both of us are going to bed!
I like “autumn, because its tone is mellower, its colours are richer, and it is tinged with a little sorrow. Its golden richness speaks not of the innocence of spring, nor the power of summer, but of the mellowness and kindly wisdom of approaching age. It knows the limitations of life and its content.”

Fibres made by electrospinning.
The aim was to create biocompatible polymer gel scaffolds to substitute the ECM (extracellular matrix). It was made from PASP (poly(asparatic acid)) modified to PSI (poly(succinimide)) and was drawn by electrospinning. It is a very effective procedure to make very thin, (some) hundred nanometer scale fibres by using electric force to draw charged threads of polymer solutions in order to make tissue alike structure. PSI is a biodegradable and it is promising for regenerative medicine and tissue engineering.

Nosocomial infections are defined as infections that are neither present nor incubating at the time of hospital admission. As patients continuously shed infectious bacteria in the hospital environment and health professionals are in constant contact with these patients, there is a need to promote a scrupulous hand washing. Also, the fact that lab coats could be contaminated by and transport viable pathogens suggests the need for further research.

You can see a wound healing under the left side of his jaw, and a closed one from there up to his left ear. Its tough being an old, feral, cat.
Poor little guy. There's something dark and matted below the right side of his mouth..., and there's more of the same on his head, between left ear and eye. After effects from someone/something trying to bite his head? He ought to retire.
And some other damage is finishing up below the outer edge of his left ear, looks like pink scar tissue closing up a vertical slash... could someone have sewn him back together? Guessing not. I'd love to get him the shots, get him fixed and keep him out of the rain somehow... Let the boo-boos on his nose all heal and whatever it takes to take down the pinkish cast around his eyes.... He can give himself a bath, I don't need the agro. Doesn't cost anything to "want", I suppose.
Its idle to imagine bathing and combing him, dressing his wounds. Scritching his ears so he falls asleep on me. Lovely aspirations, but far beyond unlikely.
If I won the lottery I'd buy a nice wooden shed, with a second door and short hallway like an airlock, inside it or outside it, so I could positively get in and out without letting him out or anyone else in. Park it in the back yard, away from houses, with windows in places he could see out of, but blank walls too, for comfort and security. Screened vents for the outdoor air, and something heated to sleep on. Shelves for exploring cats on the walls, and a real floor so he can'd dig out. Maybe some climbing stuff outside for visitors too.
He's really be retired and not on anyone's menu. I will try to trap him again.

This is a cross-sectional view of a rat facial nerve. The high resolution TEM allows us to confirm the presence of new axons (yellow) with their insulating myelin sheaths (brown) along with red blood cells (red). This facial nerve was regenerated using a nanofiber gel designed to guide damaged axons during the healing process.

Claviger beetles live inside ant nests as social parasites, being fed by the ants through trophallaxis (regurgitation of liquid food). Their structural modifications include miniaturization of their bodies, mouthparts transformed for sucking liquids and presence of tufts of hairs connected to glands which spread drugs attractive for the ants.

The biopsy of peripheral nerve observed by optic microscopy reveled many myelinated and unmyelinated axons, associated with the schwann cells. In the normal condition the myelin sheaths are organized periodically. Small changes in the structure of myelin can only be observed by electron microscopy. In this micrograph, you can be observed small details of myelin sheaths, it is evident the formation of winding roads, that view you are esthetically eye-catching, even if that tell of the image, these changes may be involved in loss of function and poor nerve conduction for the patient.

The Valley Life Sciences Building, University of California, Berkeley, CA.
The names of fields in academic science have changed so much in the last eighty years! The words on the exterior of this building are as antique as are the architectural motifs.
Today teaching departments herein are called "Integrative Biology",
and "Molecular & Cell Biology", among others.
Thanks to Flickr poster Wally Gobetz for the following description which I am borrowing:
"The Valley Life Sciences Building was built in 1930 to the design of George Kelham. Named for Wayne and Gladys Valley, benefactors of an early 1990's renovation, at 40,000-square-feet, it is the biggest building on campus, and was the largest in Berkeley and the largest concrete building west of the Mississippi when it was built. Original exterior decorations include animal-shaped ornaments and the names of eight life science disciplines. Inside highlights include a giant T-Rex skeleton fronting the museum of Paleontology."
The building is mammoth in its proportions. The footprint is approximately 250×500 feet; its figure eight racetrack of hallways extend for over a mile. The building has five floors, for a total of 408,500 gross SFt of space, of which 269,500 SFt is assignable space. VLSB was designed in a 'Neo-Babylonian' style; the four projecting pavilions at the corners of the building contain art deco elements such as friezes of garlanded ox skulls, griffins, and Egyptian-Babylonian priests.
With a notably beat-up left ear. He had some bite-marks on his neck also, similar to previous damage he's taken. Also similar to the skunk that stopped at our porch a few days ago. Jean called Oakland Animal Control and they sent two techs with the appropriate truck to collect it, and took it to wildlife rehab.
Rhodie was caught, once, by a previous neighbor, with a
box trap. Overnight, before he could be taken to the vet, he escaped from the trap, and escaped from the neighbor's basement, which has no known exit. Showed up at the regular hour for lunch at the neighbor's, the next day, too.
Some years later, I lured him into the trap I borrowed from "Fix Our Ferals", progressively moving the food bowl further and further in, and when he set off the trap, he whirled and forced his way past the door before it came down. After that he didn't even look at food in the trap. He's too wiley for that.
I wish I could play Linda Ronstadt singing "Desperado" for Rhodie, and get him to retire from his rough, tough, feral ways. He's lived a long life, semi-wild, and certainly preys on the wild rodents. He's earned a comfortable retirement. We have too many cats in the house now, but neutering and vaccinations would do him good.
Make him some kind of cat chalet, defensible, under the counter of the brick bbq in the back yard, or attached to the porch, hanging off the sequoia in the back, whatever. Make something warm he can access from the top of the fence- like a big birdhouse
