Impression smears of brain tissue are rarely rewarding on cytology as most neuronal cells rupture with the slightest amount of pressure.  What results is a Vast Pink Wasteland of Myelin…

protestants: god is not an absent father! talk to god like a friend! god is always with you! bring your problems to god, no matter how small! it’s not at all weird to call god “daddy!”

catholics: god is far too important to give a fuck about your lost keys or your algebra exam. please address your petty concerns to one of god’s ten thousand holy secretaries. if it’s really important, consider asking his mom.

Microbiologists have learned how a probiotic bacterium used to treat irritable bowel syndrome can soothe gut bacterial infections caused by salmonella, paving the way for potential relief from foodborne illnesses that affect millions of people annually.

Behold the Gastric Rainbow. Sounds gross, but it’s actually beautiful. This cross-section of a mouse intestine is labeled with a spectrum of fluorescent molecules. From the green and magenta digestive enzyme-producing cells to the red mucus-secreting cells, this is one of the most dynamic areas in the mammalian body: Each cell is replaced by another every 3-5 days.

Hitchhiking bacteria might help their host navigate via magnetic fields

Deep in the mud of the Mediterranean Sea, scientists have caught microscopic protists dancing to a strange beat—the beat of Earth’s magnetic fields. Now, a new study reveals how these tiny clusters of cells orient themselves along those fields: by letting magneto-sensing bacteria hitch a ride on their outer membranes.

Researchers used microscopes to examine protist-packed sediment taken from the bottom of the Mediterranean Sea near Carry-le-Rouet, France. When they placed a magnet with its north pole facing a water droplet from the sediment, the hundreds of protists inside immediately began to swim toward the droplet’s edge. When the researchers reversed the magnet so its south pole was facing the droplet, the protists fled in the other direction (above).
