Next addition to my Science jewelry collection! This one is for all Mycology and Medical Microbiology fans out there! Made of fused glass and a bit of sterling silver. It is inspired by Yeast Fungus pink colonies on chromogenic agar Petri dish.
Stem cells play important role in cell-based strategy for tissue regeneration. However, the conventional 'petri dish' based cell cultures do not truly replicate the complex 3D environments where cells naturally grow. In the Stupp laboratory, we are using photolithography to create textured surfaces that induce single stem cells to self-aggregate into microtissue. Compared to single stem cells, these aggregates are much more potent for regenerative medicine once implanted into the body. These specific cells will be used to grow new spinal bone.
In this image, microwells (light pink) of agarose gel were created using lithography, then each well was seeded with 250 stem cells (purple). These stem cells do not adhere to the microwell gel, but instead, they self-assembled together into microaggregates within 24 hours. The cells respond to this more natural environment by producing extracellular matrix (red) like collagen and proteoglycans. To our knowledge, this is the first ever SEM image of periosteal stem cells self-aggregating.

Forskaren. Hagastaden. This is a nine photo panorama, shot with the Canon 77D, using the 60mm lens. Tricky to shoot the lower floors as there were machines and fences everywhere.
"It is only when we are very happy, that we can bear to gaze merrily upon the vast and limitless expanse of water, rolling on and on with such persistent, irritating monotony, to the accompaniment of our thoughts, whether grave or gay. When they are gay, the waves echo their gaiety; but when they are sad, then every breaker, as it rolls, seems to bring additional sadness, and to speak to us of hopelessness and of the pettiness of all our joys."
( Baroness Emmuska Orczy )
How it's all changed. . . . life sciences, that is.
Today university research and learning are mostly at the molecular level, and departmental names say so.

False-colored SEM image of the parasite Trypanosoma brucei gambiense (15 micrometers long) responsible for human sleeping sickness in Western and Central Africa. Human innate immunity is overpowered by this parasite through a mechanism that we have discovered in our laboratory. We have dedicated the past two decades to study the molecular arms race between humans and trypanosomes and discovered the importance of resistance to these parasites in human evolution.

This axon is extending through a nanofiber gel across a critical size defect restoring motor control in rat facial tissue. The nanofiber gel is designed to guide damaged axons during the healing process, and it's currently being developed to treat peripheral and spinal nerve trauma. This sample was embedded in resin, sectioned, and stained for a cross-sectional TEM image. The axon (yellow) is seen within its insulating myelin sheaths (purple), the intracellular structures, such as microtubules, can be seen inside the axon.

From space toilet (left) to urine processor (right). From potty tofaucet!
About 95% of urine is water. Why not recycling in space? In the International Space Station, water is evaporated from urine, condensed, and filtered to make potable water. Yes you technically drink your and your colleagues urine!
Recycling water in space is more cost effective than bringing it from Earth

The image shows the Jujubinus exasperatus radula, a complex structure used by molluscs for feeding, sometimes compared to a tongue. It is a minutely toothed, chitinous ribbon, which is typically used for scraping or cutting food before the food enters the esophagus. Jujubinus exasperatus is one of the most beautiful molluscan gastropods of the mediterranean sea, characterized by a conical shell of 7-15 mm, showing complex patterns of bright colors. It is common in prairies of Posidonia oceanica at 0-30 m, where it grazes on small algae growing on Posidonia leaves by using its radula.

Coloured scanning electron micrograph of brushite platelets(crystals) growing on a glass surface coated with protein. These crystals often grow in bundles that make them look like flowers. Brushite is a calcium phosphate mineral that can be a precursor to apatite, the mineral content of bones and teeth. By studying how the apatite mineral forms in the presence of proteins, researchers are hoping to be able to eventually form an enamel-like replacement for treating decayed tooth enamel.

They're both very beautiful, he appears to lead a rougher life. As a neutered female cat, she carries far fewer wounds, Even now, I believe he'd benefit from neutering, besides just getting shots from the vet and dressing his current boo-boos.
Its easy to tell them apart once you know the 'tells". She has three white rings near the end of her tail, equally spaced. Like: (end) --|-|-|------- And two, merged, white lines from her forehead up to between her ears, with two dark line outside of the central white ones.: .|.|.::.|.|.
In contrast, he has three unequally spaced white rings on his tail, something like: (end) ----|--|-----|-------. And his white 'forehead' stops well in front of his ears: ..|.|...|.|.. , with 2 pairs of black lines going over his head and joining the pattern on his neck.

Infections caused by methicillin-resistant strains of S. aureus (MRSA) range from those of the
skin and surgical sites, infections relating to catheters and prosthetic implants, to bacteremia,
endocarditis and pneumonia. In this picture, Staphylococcus strains isolated from human patients were analysed for adherence and internalization in human epithelial cellsthe in order to better
understand their mechanisms of pathogenicity. Two cells (green) are in the process of epithelial cell (red) invasion via a zipper-like mechanism.

Here we see the sarcomere units in the muscle tissue (red) of a mouse that was injected with a regenerative nanofiber matrix (blue). The nanofibers were injected with a micro-manipulating device that allows us to align the nanofibers parallel to the muscle tissue. The alignment of nanofibers allows proliferating cells to match the organization of the neighboring muscle thus accelerating the healing process after injury.

This scanning electron microscope image depicts a porous silicon (pSi) microparticle being recognized by the filopodia of a macrophage cell, the first step of phagocytosis. These pSi microparticles are strategically engineered to overcome the biological barriers of the body and accumulate at diseased vasculature exploiting their unique shape that facilitates their interaction with the blood vessel. These microparticles can be further engineered to shuttle nanoparticles to sites of disease, decoupling the multiple tasks typically required of a traditional nanoparticle. This multi-step approach allows for increased accumulation of nanoparticles at the target site.

Detail of the pollen grain surface of Piptolepis sp., showing subechinolofate ornamentation (spines on walls, disorganized, do not form well defined gaps), densely perforated, conical spines, perforated only in the base.
The pollen morphology is very important for the classification of Asteracea groups, which includes sunflowers, lettuces, chamomile, chicory, artichoke and several species with pharmacological potential such as “carqueja” (Baccharis L.) and “guaco” (Mikania glomerata Spreng), both Brazilian tea medicines, besides the ornamental usage.
This image is part of a study that deals with the morphology of the pollen grains of the subtribe Lycnophorineae, belonging to Asteraceae group. The objective of this work is to find new morphological characteristics that are able to delimit the species and genera of these plants, as well as to infer a probable pattern of evolution within the subtribe Lycnophorineae. This study was developed by the researcher Raquel Maria Batista Souza de Souza at the Laboratory of Palinology of the National Museum of UFRJ, which after the fire had its continuity hampered by the loss of its scanning electron microscope. With the support of the National Institute of Technology (INT), this image was obtained by the researcher Carla Ramos Moreira in the Dual Beam Helios Nanolab of this Institute.
