Cyanobacteria produce oxygen as a byproduct of photosynthesis, which is thought to have converted earth’s atmosphere from a reducing environment to an oxidizing one (a long, long, long time ago). (x, x)

I’m an artist with a molecular biology degree from the University of Washington, and I’ve been working on making science infographics for several months now. 
This week I made an animated identification chart of North American butterflies. You can check out the full sized GIF here or pick up a poster for your room here :)

Inside the world of infection
Fungal pathogens manage to simultaneously pacify their plant victim’s defences whilst seizing host nutrition, creating a very difficult situation for any plant that becomes infected.
Here you can see three different stages of the fungal hyphae of Magnaporthe grisea invading and taking-over a plant cell.
Top panel: After 48h of infection
Middle panel: After 72h of infection
Bottom panel: After 96h of infection
Rice blast disease, which is caused by M.grisea, is one of the greatest pathogen threats to rice crops globally and since rice is an important food source its impact can be devastating.
Scientists from the Institute of Biological, Environmental and Rural Sciences at Aberystwth University, which is strategically funded by BBSRC, are studying the mechanisms behind fungal pathogen infection eventually hoping to reduce this major threat to modern agriculture.

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.

The dragon blood tree, native to the Socotra archipelago in the Indian Ocean, gets its name from its distinctive red resin, which is used in dye, medicine, and incense. (sources: 1, 2)

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.

These black roses grow naturally in the tiny village of Halfeti, Turkey. The particular soil conditions and pH levels of the groundwater from the river Euphrates causes the roses to fade from deep crimson to black during the summer. (source)
