Evolutionary biologist Julia Van Etten established an improvised laboratory in a motel room following federal science funding freezes, where her team discovered two new species of the single-celled organism Paulinella. Reported by The New York Times, the discovery brings the total number of known photosynthetic Paulinella species to six and provides researchers with a living model to study how complex photosynthetic life originated on Earth.
Motel Room Science After Federal Freezes
Jerry Cans and Microscopes on Bedside Tables
To continue her work without institutional backing, the researcher rented a motel room and converted it into a workspace. Jerry cans filled with brackish water lined the motel walls, while buckets of marsh grass sat on the floor. Microscopes rested on bedside tables, and a “Do Not Disturb” sign hung on the door. Despite the financial setbacks, the team proceeded with field sampling and analysis.
A Green Dot Beside a Highway Dock
The breakthrough occurred when Dr. Van Etten drew water from a casual dock alongside a highway. Amid a mixture of brownish-yellow plankton, she identified a small green dot that microscopic imaging confirmed to be a Paulinella cell.
The newly identified microbes are scaled, grenade-shaped organisms containing sausage-shaped green structures inside. This finding expands the recognized diversity of photosynthetic Paulinella strains to six globally.
Replicating Ancient Symbiosis in the Lab
Almost all complex photosynthetic life on Earth, including ferns, algae, and sequoias, traces back to an event 1.5 billion years ago when an ancient single-celled organism engulfed a photosynthetic bacterium and converted it into an energy-generating organelle. Discoveries two decades ago revealed that a similar photosynthetic merger occurred a second time in Paulinella roughly 100 million years ago.
Because the Paulinella symbiosis is relatively recent on a geological timescale, the organism remains in an intermediate stage of transition. Researchers study these microbes to reconstruct the foundational steps that enabled modern plant life. The team now aims to investigate the mechanics of this ancient symbiosis with the goal of eventually replicating the process in a laboratory setting.
