In 1963, Bonnie Dalton joined NASA as a microbiology researcher. During her career, she helped to establish NASA's Life Sciences program at NASA Ames Research Center. Amongst other topics, her research focused on astrobiology, how to counteract the effects of gravity on bone and neural systems using centrifuges, a human bed-rest facility, a biocomputation center that shows biomedical changes, and an animal care facility.
In this 1976 photo she works with a test module for the biological experiments on NASA's Viking landers.

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

No, she is not. Try telling her that. Her natural assumption is that if something is going on, she should be in the middle or at the front edge. Food in a bowl? She's there. Cat toy? Stuffed animal? feather on a string on a stick? Laser pointer? Every time. Front and center. She is also the most likely to dash around excitedly- galumph galumph down the hall, up the steps to the bathroom, turn around, galumph galumph, flying down the stairs, dashing through the broken ground of the living room with one of my projects going, and kapow! Up onto the glider chair, scramble up the cushion of the back and sit on top of it all. For a moment Rinse. Repeat.
She's smaller all around than Rhodie, getting ready to yawn or growl / hiss at me here. This is 5 weeks after she was fixed, 4 weeks after I released her. Her nose is healing where she had tried to use it to pry open the cage when I first caught her. I stuffed a dishtowel into that diagonal corner and tied the cage door shut with the soft iron ties used for bread and produce bags.
She and Rhodie both have big, broad, feet, suitable for a life outdoors.

Poor little guy, he's not really this clean looking, he leads a tough life and he is a little gray and weather beaten. Scratches or bite marks on his nose and face, sometimes healing wounds on his neck. That's scary. The exposure here is iffy and I had to push the controls around to get any kind of useful image.
I tried for more than a year to lure him into one of Fix Our Ferals' traps. He set it off once but escaped, and never fell for it again. I'd love to get him a vet visit, shots, and have him fixed. I doubt he'll ever retire, he's been wild his whole life. But he was friends with our neighbors who have since moved, and we've always admired him.
A young female cat who looks quite like him appeared a couple years ago, in a family way. We fed them both, of course. I did catch her and one set of new neighbors caught the kittens she was raising under their deck- two went to new, forever homes, they kept two sisters. Mom got fixed, full shots, and the tip of one ear clipped, so anyone can tell she's been to the doctor. Abby named her "Sunflower". But Rhodie here is too cunning for the trap, and he'll always be just beyond reach, I've reluctantly concluded.

Our feral pal, entrusted to our care by a charming neighbor who later retired and moved away. She named him Rhodie, because he hung out under a rhododendron in her backyard. He had been injured, hit by a car perhaps, and healed in the neighbor's extensive garden. She said she managed to sweet talk him into coming close enough for brushing the top of his head with her fingers, but he was wild through and through, and wiley.
He was beautiful and robust, but in later years got injured by other cats, possums, raccoons, foxes or ???. You can see some combination of scab or something adhering to a wound under his jaw here.
We fed him and tried to trap him for a visit to the vet to be neutered and get his immunizations, but after setting off a trap, once, and escaping, he never fell for it again for me. We fed him and worried about him and were always glad to see him. But we haven't seen him in many months. Maybe he's found a home somewhere, or reached the end of his story.
Rhodie is a feral who our friend and neighbor Nancy met when he was recovering from a injury in her back yard. He liked a spot under the Rhododendrons, so Rhodie was his name. She talked to him and fed him and he recovered from a leg injury - hit by a car as I recall. She caught him in a humane box trap, and planned to take him in for getting fixed and shots and all the mod-cons, the next day, but he got out of the trap, in the night, and got out of her basement, which has no known exit. He showed up for breakfast, the next morning, but was a bit stand-off-ish.
Nancy managed to scritch him on the top of his head, in time, but never got closer. She left us a big bag of dry food and his water bowl when she moved away, and we've been feeding him and worrying about him too, ever since. When I was trying to catch him myself, Nancy *and* one of her former housemates both sent material support, which illustrates how nice they are, and what an appealing guy he is. Alas, he was too wiley for me to catch. Every winter we worry about him and put out food whenever we see him, but its clear he's dining at more than on establishment, as well as al-fresco. Good on him.
Some years after we took over, another cat with remarkably similar markings showed up in the neighborhood... small, and distinctly pregnant. She was named Sunflower by our daughter, who is good at cat names. Our delightful neighbors, who had bought Nancy's house, had been helping feeding outdoor contingent, and they found where Sunflower hid her kittens under a deck in their backyard. They met the kittens and started feeding them solid food when it seemed right.
I managed to trap Sunflower, get her to the vet, fixed, full set of shots, and when she'd recovered for a week, we turned her loose. She tolerated having my scritch on top of her head, twice a day, along with feeding, but didn't warm in any way to me. The neighbors kept two of the kittens and found forever homes for the other two. We believe Sunflower looks like Rhodie because he's her dad, by a feral mother we may or may not have met.

Ticks are a parasitic insect with mouth parts specialized for sucking blood. When the tick is viewed from below, the barbed hypostome is visible. The the barbs point back toward the tick, making the insect difficult to remove once the hypostome is inserted into the skin. The upper side of the hypostome (not visible in this image) is a channel which moves the tick's saliva into the host and the host's blood into the tick.
To prepare this sample, the insect was removed from the skin and frozen to kill it. To take the image, the tick was laid on its back on the ESEM metal peg and scanned.

The analysis by electron microscopy is a very important tool for some diseases of difficult diagnosis. The alveolar soft part sarcoma is a rare disease, but diagnosis is difficult by traditional techniques. For that, in many cases the Transmision Electron microscopy is a ideal tool to stablish the precise diagnostic. In this micrograph we can observe polygonal crystal structures localized into cytoplasm of cells obtained of alveolar sarcoma. It is inevitable to go with view the forms linear perfectly ordered comprising these crystals.

He's probably blissed out, possibly purring. You can see what a hearty, big fellow he was. Long haired American tabby, a kitten from a pair of adults Lori owned when I met her. Like Abby's cat Moonlight, Mothra had all the hallmarks of a male cat- hail fellow well met good regard for everyone, with a high likelihood of biting or clawing once in a while, anyway. Easy affection when sleepy, charming when he wanted to be, full of energy sometimes, subject to sudden dashing around impulses. There was a couch in my living room at one point that he'd scoot around under and up the back of, clawing his way along the couch with his back to the rug or the wall. Pop! Up comes his little head at the back of the sofa, then swish swish swish he'd pop out down by your feet. He had a whole routine for running around on the furniture in that apartment - sofa to chair, jump into the bedroom, land on the bed, bed to floor, scoot back out and across the living room on the floor, jump onto the sofa and start again.
The box is a Brooks Brother's box, one they could fold up your suit and pack it for shipment in. Its the box I brought my first Brooks Brother's suit home in, and kept for years as a memory box for large, flat stuff. I was 19, 1976, when I bought the suit, I actually out-grew it, besides being too heavy around the middle! Beautiful, grey wool flannel. My parents paid for it.
I bought a second Brooks Brother's suit for myself in 1996, for Jean and my wedding. Dark blue the second time around, and I got a gray one for my brother, who was my best man. They're very nice suits, if you like that sort of thing.
