The image above shows a developing zebrafish eye 3 days after fertilization. From this perspective, we are staring directly into the eye of the zebrafish and can appreciate both its beauty and its complexity. At this stage, the cells that comprise and…

Cross section of oak wood, showing every reason that made an oak tall and strong. The large pores are vessels that are responsible for transporting (more accurately, pumping/pushing) water from the root system to the tip of the tree. The densely packed…

Tangential section of wood of Chinese holly. This is how it looks like when you do a cut that’s perpendicular to the radius of the stem. The vertical lines are vessels transporting water from roots to leaves, while the circles are clustered ray cells…

Microscope image of the epidermis of a spiderwort leaf with well-organized stomata in high density. Stomata (singular stoma) are like little mouths on the leaf surface, specialized in gas-exchange – CO2 enters a plant through them. The opening and…

Lower leaf epidermis of the stonecrop plants showing puzzle shaped epidermal cells with scattered stomata. Stomata (singular: stoma) are like little mouths on the leaf surface, specialized in gas-exchange – CO2 enters a plant through them. The pairs of…

This cross section of an oleander (Nerium oleander) leaf reveals two beautiful mineral crystals inside. Leaf cells are stained red. Adapted to dry conditions, this leaf possess three epidermal layers to prevent water loss, below which there are tightly…

These colorful fractions were obtained upon purifying a synthetic small-molecule through flash column chromatography. Though most of these were impurities (bright colors in organic chemistry is usually not a great sign), it served as a reminder to…

The adaptation of the opportunistic human pathogen Pseudomonas aeruginosa often produces phenotypic diversity. Here, mutants isolated from a genetic screen show notable differences in phenotype: the production of pigments, size, shape, and texture. The…

What you’re seeing is the brain of an axolotl, an organism known for its ability to regenerate many organs including the limb, heart, and spinal cord. The different colors (blue, green, red) represent some of the neuronal cell types present within…

Gene therapy is an approach to treating genetic diseases by re-introducing a functional copy of a gene into cells to replace the mutated, disease-causing gene. To get these genes into the cells, scientists create a vector by packaging the DNA encoding…
