This terrarium hasn’t been opened in 40 years! It is completely self-sufficient—the bacteria in the compost breaks down dead leaves to give the plants the carbon dioxide they need, and the moisture in the air condenses on the glass and returns to the soil to feed the plants’ roots.

Long features dubbed tiger stripes are known to be spewing ice from the moon’s icy interior into space, creating a cloud of fine ice particles over the moon’s South Pole and creating Saturn’s mysterious E-ring. (via APOD: 2014 April 6 - Fresh Tiger Stripes on Saturns Enceladus)

Barrett’s esophagus is diagnosed when simple columnar epithelium with goblet cells replaces the normal stratified squamous epithelium lining of the esophagus. Goblet cells are usually found not in the esophagus but in the lower GI tract. This micrograph shows the Barrett’s esophagus cells on the left and the normal squamous epithelium cells on the right. Barrett’s esophagus is highly linked with esophageal cancer.

A liana is a woody climber that starts at ground level, and uses trees to climb up to the canopy where it spreads from tree to tree to get as much light as possible. Lianas are especially characteristic of tropical moist deciduous forests and rainforests. These climbers often form bridges between the forest canopy, connect the entire forest and provide arboreal animals with paths across the forest. This is a Monkey Ladder vine.
