regular lobsters start out as just little lobsters but spiny lobsters start out as these beautiful weird larvae that also evolved to ride on top of jellyfish. This jellyfish is too small though!!!

Church of Whale Fall

You are extraordinary

One of a kind and yet

Millions of ones

Ever changing

You are the heartbreak

And the heartbeat

You are the master

And the student

You are evolution

And stability

You are the life

And the spark

And the answer

And the question

And in the times that you feel lost

Please remember all of these things

That make you

Extraordinary

Life has been busy and stressful and very very strange but at least pathology can always be depended on - please enjoy this weird and invasive mammary carcinoma from a dog.

The Summer Games are here, so let’s meet the gold medal champion for fastest shark in the sea: the shortfin mako shark (Isurus oxyrinchus)! This agile predator fish is one of the world’s fastest swimmers, able to reach a top speed of over 40 mph (64.3 kmh). For perspective, the current 100m freestyle world record holder swam at an overall speed of 4.7 mph (2.9 km/h). A model of this shark can be found in the Museum's Hall of Biodiversity.

The Birth of Brain Cells

This might look like a distant web of galaxies captured by a powerful telescope, but it’s actually a microscopic image of a newborn nerve cell. The human brain contains more cells than there are stars in our galaxy, and the most important cells are neurons, which are nerve cells responsible for transmitting and processing electro-chemical signals at up to 320 km/h. This chemical signalling occurs through synapses—specialised connections with other cells, like wires in a computer. Each cell can receive input from thousands of others, so a typical neuron can have up to ten thousand synapses—i.e., can communicate with up to ten thousand other neurons, muscle cells, and glands. Estimates suggest that adult humans have approximately 100 billion neurons in their brain, but unlike most cells, neurons don’t undergo cell division, so if they’re damaged they don’t grow back—except, apparently, in the hippocampus (associated with memory) and the olfactory bulb (associated with sense of smell). The process by which this occurs is unclear, and this image was taken during a project to determine how neurons are born—it actually depicts newborn nerve cells in an adult mouse’s brain.
