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.

Scientists present the first evidence that marine cyanobacteria release vesicles—billions and billions of vesicles.
