The brain is made of up billions of neurons and even more connections between neurons. We can get an idea of how neurons are connected across the human brain using a type of brain scan called diffusion-weighted magnetic resonance imaging (dMRI). How…

Image contributed by Yu Wang, a third year graduate student at Harvard Medical School. Glial cells support the proper function of neuronal cell types and are also responsible for cleaning up cell debris such as leftover neurotransmitter molecules (what…

This is a layer of epithelial cells that was subjected to sever freeze-thaw cycles before being imaged at 400x magnification, which caused the membranes to rupture and form these arrays of crystal-like structures. When frozen, the water inside the cells…

The patterns seen here are called interference rings, or Newton’s rings, and are generated when light waves reflect off of two glass surfaces that are in very close proximity to each other, such as a glass microscope slide and a cover slip. Imperfections…

These images show cross sections of the different compartments of the developing gut in a chick embryo: esophagus (top), small intestine (middle), and large intestine (bottom), at days 6, 8, 10, and 14 (left to right). As the chick develops, the shape of…

    Bovine Pulmonary Artery Epithelial (BPAE) cells have been featured several times in the gallery and on our Instagram; incase you missed them, check out Kaleidoskeleton, Plumotion, and Cytoskeleton Four Ways. In this stunning collage, BPAE…

      This image shows an unwound small intestine from a mouse embryo 15 days after conception. Blood vessels (blue) are responsible for carrying oxygen to the muscles of the gut and transporting dissolved nutrients from the intestine to…

By Andrew Wong, a second year graduate student in the Applied Physics program at Harvard University.       The increase in global energy demand and subsequent carbon dioxide emissions has driven advancements in renewable energy generation technologies…

  A grain of pollen contains a sperm cell, surrounded by walls to keep it safe. The inner wall, or intine, is less sturdy and made of cellulose, but the outer wall, or extine, is made up of a very stable and tough polymer called sporopollenin. It…
