Previously undetected cyanobacteria are symbionts of dinoflagellates.

Photosynthesis can happen in more than one way.  

Injecting photosynthetic microbes into oxygen-starved heart tissue can improve cardiac function in rodents. 

Metabolic activity, not light, drives the circadian clock in cyanobacteria.

Photosynthetic cyanobacteria sense light in much the same way as a human eyeball, scientists show.

Scientists establish a functional circadian rhythm in bacteria that don’t possess one naturally.

A hidden toxin stalks marine mammals off the coast of California and kills dogs and cats farther inland.

US dogs face a deadly threat from algae-spawned toxins lurking in lakes, but there may be an antidote.

Evolution of Y chromosome; delivering gene with “bionic ears”; diversity of an important cyanobacterium; charting genome-sequencing progress; blockbuster pharma deals

A marine cyanobacterium possesses astounding genomic diversity, yet still organizes into distinct subpopulations that have likely persisted for ages.
