me explaining to my grandma that the turkey tail and golden oyster mushrooms and birds nest fungi growing on her huge backyard tree stump are simply eating the dead wood to return it to the soil and they're cute and colorful and add to the whimsy of her landscaping and are not causing the weeds in other places of the yard or harming her little white dog

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.

Ammonites were some of the most diverse organisms in the ancient ocean. The Museum holds one of the world’s largest collections of ammonites, containing nearly two million specimens that represent 300 million years of Earth’s history!

Take a look at this newly diagnosed Multiple

Myeloma (MM) case!

MM is a type of cancer developed by the overproduction of plasma cells in the bone marrow (B-cell lineage). Plasma cells are responsible for the production of antibodies to fight infection within the body.

Helpful lab findings

C- hypercalcemia

R- renal failure (increased CREA+BUN)

A- anemia

B- bone lesions

Confirmatory testing

1. Serum protein electrophoresis: spike in the gamma wave aka monoclonal paraprotein (M-spike)

2. Immunofixation protein electrophoresis: identifies the type of immunoglobulin (heavy chain) present (IgA, IgG, [gE, etc.)

3. Free Light Chain Assay: determine if the immuglobulin is

Kappa or Lambda

4. Bone Marrow aspiration: take a look at the first picture.

60% of the bone marrow is most likely plasma cells

Different types of MM

-Smoldering MM (increased plasma cells in bone marrow & high protein. Does NOT follow CRAB)

-MGUS (decreased plasma cells in bone marrow)

-Light chain amyloidosis

Teachers: Earn graduate credit and advance your career in six weeks with our flexible online courses! Connect with the Museum’s scientists, labs, exhibitions, and specimens. You can choose from a variety of courses ranging from Marine Biology and the Solar System to Climate Change and Virology. The courses are asynchronous, providing participants with the flexibility to complete weekly activities at their own pace—and can be taken anywhere at any time! Subject to school/district approval, courses may be used toward professional development, salary advancement, and recertification. Sign up for our summer session today—classes start July 8!
