Amoebae stained for actin polymer are pseudocolored and organized into a mosaic pride progress flag. Each stripe has around 30 amoebae.

Meta literally created a LGBTQ exception for calling someone mentally ill as an insult. You can't do it for any other group except LGBTQ people.
The image is from a "Transparency Center" document and lists guidelines regarding acceptable and prohibited content for insults. It mentions:

1. Insults about:

Character, such as cowardice, dishonesty, criminality, and sexual promiscuity or immorality.

Mental characteristics, including but not limited to accusations of stupidity, intellectual capacity, and mental illness, as well as unsupported comparisons among politically correct (PC) groups based on inherent intellectual traits.

2. Highlighted section:

The document allows allegations of mental illness or abnormality when tied to gender or sexual orientation, referencing political and religious discourse about transgenderism and homosexuality. It also acknowledges the non-serious use of terms like "weird."

Looking down at the head of a transgenic 17-day-old #zebrafish, blood vessels in magenta, lymphatic vessels in green. Extended depth of focus #WeinsteinLab 🧪🔬
A highly detailed gray image of the dorsal view of a zebrafish head pointing to the left with two large black eyes on either side.  A complex network of magenta blood vessels look like tangled spaghetti in the center (brain region) of the image.  There are dozens of ameba-shaped green cells around the brain blood vessels and a few well-defined green lymphatic vessels on either side of the head.  Protruding from the skin on each side of the head, to the right (posterior) to the eye, there are three volcano-like structures with long, transparent, hair-like projections.  These are hair cells that the fish uses to sense changes in water flow.

#ZebrafishFunFacts: Did you know the popular WT strain 'AB' originated from a mating between strain A & strain B purchased by Charline Walker on two separate occasions from a pet shop in Albany, Oregon? This helped transform #zebrafish from household pet to a model of human disease & development. 🧪

“The collective diffraction of light produces an array of colors. When the fish contracts and relaxes its muscles to swim, the sarcomeres slightly change in length, causing a shifting rainbow effect.” #scicomm #animalcoloration #iridescence #fish www.sciencenews.org/article/tran... 🧪 🐟 🌈

These transparent fish turn rainbow with white light. Now, we know why
Repeated structures in the ghost catfish’s muscles separate white light that passes through their bodies into different wavelengths.

Scoliosis is a common condition in which the spine curves to the side and rotates, often onsetting during adolescence. In our lab, we generate zebrafish with scoliosis-like spinal curves to try to understand the causes of this disease.

#ZebrafishFunFacts: While Kimmel et al. (1995) famously standardized the embryonic development of #zebrafish, Parichy et al. (2009) takes it one step further with characterizing postembryonic zebrafish. They establish Standard Length (SL) as measure of developmental progress rather than age. 🧪

Exciting preprint from @chiarafornetto.bsky.social's research on colour vision in zebrafish! Turns out their spatiotemporal vision is mainly built on R/UV cones, and G/B cones provide supportive functions like background subtraction! 4 cones allows more computation earlier in vision! Have a read!(:

highly detailed dorsal view of three fish with scales and lymphatic vessels shown in different colors with curved bodies as if the fish were swimming.  the two fish on the outside are facing downward, and the fish in the middle is facing upward.  the left most fish has magenta scales and green lymphatic vessels, the center fish has blue scales and orange lymphatic vessels, and the right fish has green scales and purple lymphatic vessels.
