First Prize (Joint)

Image from microscope-black background with yellow nuclei, some surrounded with cyan RNA "clouds" and magenta dots around all nuclei.

Viruses seek to hijack host cells to replicate and spread, while cells evolve mechanisms to detect and suppress viral invasion. Here, we show that P-bodies (ancient cytoplasmic organelles) can trap SARS-CoV-2 RNA (cyan). The cell nuclei are yellow.

First Prize (Joint)

Image taken on microscope-black background with cyan astrocyte in the middle

Astrocytes are the most abundant cells in the human brain—even outnumbering neurons by 3:1 in some regions. We used these images to confirm that our dish contained exclusively astrocytes before performing additional experiments.

Yohan Ricci Zonta

Third Prize

Image taken with microscope-black background with cyan neuron "growing" from the bottom of the image with yellow and magenta dots surrounding the cell.

Neurons are the longest-lived cells in the body; most neurons survive for our entire lives. Connections between neurons can be seen in the image here: green and yellow fibers project outward from the nucleus (blue/grey) to connect with nearby cells

First Prize

First Prize

Third Prize (Joint)

Black background covered with cyan fibers with yellow nuclei and pink microglia

Your brain contains a large network of cables, over which electrical impulses are constantly exchanged. Oligodendrocytes wrap these cables in an insulating layer of myelin, speeding up brain signals by up to 100-fold.

Rianne Gorter

Third Prize (Joint)

Black background with red, white and blue lines that merge to form the shape of a heart

This image shows a transparent mouse heart, with the nerves in blue and blood vessels in red. We found that after spinal cord injury, nerve fibers in the heart are lost, leading to heart disease.

Third Prize

Mouse cerebellum-cyan and orange fibers merging together on a black background

This is a slice of mouse cerebellum or ‘little brain’. The nerve cells processes (orange) through which electrical signals are transmitted. The myelin (blue), an insulating layer, which ensures that nerve signals can travel at superspeed.

Rianne Gorter

Fourth Prize

"fan" of yellow tissue on a black background

Mouse colon section stained with an oxidation sensitive probe to study oxidative stress in tissue. The probe stains lipids and lipid membranes. Lipids peroxides oxidize the probe which results in a change in fluorescence (indicated by yellow to red).
