vacuoles

1. To exhale all of the choking, sickening fumes that have gathered in the vacuoles of my lungs as I’ve watched others live loves

2.To put my hands where my mind is and to keep my mind where my hands are 

3. To close my eyes when I feel sunlight kiss my cheeks and to smile at the way it’s lips dance and to fold the memories of these moments into the lining of my heart until it glows

4. To trust the winds that guide me and not to always go where I am urged

5. To no longer fear burning too hot, or running out of light and love and wonder to pour into the world, to no longer fear having none left for my own heart

6. To love stars without counting them and to love myself  the same way

7. To exhale love with every breath of life I take

8. To push and pull on my own bones until they stretch and grow and reach out long enough to grab each idea floating past me

9. To grow my soul past what I can imagine tonight

Produced by the National Institute of Allergy and Infectious Diseases (NIAID), this digitally-colorized scanning electron microscopic (SEM) image of a dry-fractured Vero cell revealed its contents, and the ultrastructural details at the site of an opened vacuole, inside of which you can see numerous Coxiella burnetii bacteria undergoing rapid replication. Please see the Flickr link below for additional NIAID photomicrographs of various microbes.

Infection of humans by Coxiella burnetii bacteria usually occurs by inhalation of these organisms from air that contains airborne barnyard dust contaminated by dried placental material, birth fluids, and excreta of infected animals. Other modes of transmission to humans, including tick bites, ingestion of unpasteurized milk or dairy products, and human to human transmission, are rare. Humans are often very susceptible to the disease, and very few organisms may be required to cause infection.

me, in ur ear; cells cells they're made of organelles try to pull a fast one the cytoplasm gels the nucleus takes over controlling everything the party don't stop til the membrane blocks the scene inside the vacuole we can float around for hours having fun with chloroplasts loving sunlight showers cells cells they're made of organelles

Requested Anonymously

This adorable little grass starter, like a lot of of its type, gets energy from photosynthesis. Professor Halie did a phenomenal job describing that process in Bulbasaur’s entry, so instead I’ll focus on something else: Snivy’s drooping tail.

Snivy’s tail droops in the same way that plants wilt, their once strong leaves and stalks losing shape and sort of just flopping over as if they were melting.

You don’t typically see this kind of behavior in animals, because plants an animals have very different cell structures.

Obviously, plants have chloroplasts to photosynthesize and animal cells only have mitochondria. Plant cells have thick cell walls, and animal cells have thin cell membranes. The important difference is in a component called the vacuole. The vacuole stores water in a cell. Plant cells typically have one very large vacuole, and animal cells have many smaller ones (called “lysosomes” in this image)

Because the vacuole takes up so much area in the cell, when it is full, the plant becomes very stiff. But when the vacuole is empty, whether due to dehydration or other health problems, the cell becomes lopsided and sort of floppy. Plants don’t have bones, so when their cells aren’t robust and full of water, they wilt.

Snivy’s tail, then, must be more similar to plant cells than animal cells. Or, if it is still made of animal cells, they must be strange forms of animal cells with large vacuoles, such that when it is unhealthy, it wilts.

The cells in Snivy’s tail contain large vacuoles, which are full when healthy to keep the tail robust and stiff. When it’s unhealthy or dehydrated, the cells cannot be supported upright by an empty vacuole and starts to wilt.

In some grass types (such as Bulbasaur), it’s fairly clear which parts are animal and which parts are plant. In others, not so much. It’d be very interesting to see the cells of these pokémon, and to see whether they are actually more like plants or animals, or something else entirely.

Vesicles, vacuoles and plant cell walls

Vesicles: membrane-bound sacs found in cells (can be visualised as a bubble of liquid). They are made up of a variety of molecules and can form naturally or prepared. They are used to store or carry different substances around the cell. Most vesicles have specialised functions, depending on the materials they contain.

Vacuoles: found in all plant and fungal cells and maintains cell stability. It is filled with water containing organic and inorganic molecules so that it pushes the cytoplasm against the cell wall, making the cell turgid and helps support the plant.

Plant cell walls: found on the outside of plant cell surface membranes. It is made up of cellulose, which forms a sieve-like network of strands. This makes the cell wall strong. It is held rigid by the pressure of the fluid inside the cell (turgor pressure) so it supports the cell and the whole plant. 

Definitions:

  • Turgid-describes a cell that is full of water and the pressure of the cell wall prevents more water entering.
Going Solo (Closed Rp)

It was his first day, here at the prestigious Beacon Academy. “Geez, it’s so large, but who cares about that anymore?”, he asked himself with a snicker. He just recently signed up about five months after initiation, so he has no friends, aside his weapon, and no team, or Family since they are in Vacuole.

OB Science Time: The Castor Disease

Episode 3x03 had a lot of science in it, so it’s time for a second edition of OB Science Time to discuss the science behind the Castor Disease, or “glitching”.

Scott says, upon examining Seth’s brain that “it looks like Swiss cheese” and he mentions encephalopathy as well as Creutzfeldt-Jakob disease. Encephalopathy is an umbrella of diseases categorized by an altered mental state, including symptoms such as loss of cognitive function, subtle personality changes, and inability to concentrate. We certainly saw these symptoms in Seth, with his inability to perform well on Paul’s syllogism test, as well as his violent outburts and his mutterings in the stairwell before his final episode.

Creutzfeldt-Jakob disease is caused by prions, which are misfolded proteins that then act as an agent to convert their properly folded counterparts into more prions. The classic result of these prions is a change in the gray matter of the brain, causing large vacuoles to form, giving the appearance of Swiss Cheese. Symptoms of this disease include memory loss, personality change, and hallucinations, as well as jerky movements and seizures.

My guess is that the Castor disease functions in a similar manner as these diseases. Scott also mentioned the presence of amyloid plaques in Seth’s brain, which are protein aggregates. These aggregates, which could be made up of prions, could be causing neurodegeneration, leading to the Castor glitches and altered mental states.

It will be interesting to see what Cosima and Scott do with this knowledge, and more importantly, how the Castor clones will go about finding a cure for their malfunction.
