Biology Section

The Biology Section is the Niflheim colony’s scientific department for working with the planet’s atmosphere, organisms, and food crops. Its remit is both practical and hazardous: the colony depends on biological interventions to make its surroundings more habitable, while its first method for identifying local health threats is to expose Mickey Barnes, the Expendable, to them. The department’s work therefore connects scientific investigation to the colony’s infrastructure of survival—and to the question of how much its members understand about the life they seek to manage.

Mandate and methods

A colony’s first biological priority is to determine whether local microbes threaten human health. On Niflheim, that priority becomes a direct assignment for the Expendable: samples and organisms isolated from the environment are tested by exposing him to them and waiting to see what happens. The procedure makes a person who can be regenerated an instrument of research, turning the colony’s biological uncertainty into a bodily risk concentrated on one worker.

The department’s purpose is not limited to identifying danger. Before the expedition commits to Niflheim, Marshall considers continuing to a secondary target because the planet’s climate and atmosphere require people to wear rebreathers outside. Dugan and other members of Biology argue that engineered algae could eventually raise atmospheric oxygen to survivable levels. The projected timetable is severe: the change might not come within the lifetimes of the adult colonists, but could arrive within the lifetimes of embryos carried aboard the expedition. Their proposal helps persuade Marshall to attempt settlement on Niflheim, making biological engineering part of the colony’s decision to stay.

Work at the new settlement

Biology is represented in the first landing party on Niflheim, which arrives in a lander piloted by Nasha. The party includes a biological isolation chamber, medical personnel, Biology personnel, and Mickey. This early deployment places biological containment and investigation alongside the practical business of establishing a foothold on a world whose air and climate are not immediately compatible with human life.

The department’s work also reaches into crop cultivation. A new phage is prepared for testing on the colony’s tomatoes, and Mickey is told to return promptly because applying it may be dangerous. The episode shows that research is not confined to the laboratory: an intervention intended for a food crop requires both a test and a worker expected to help administer it. It also locates Biology within the colony’s food pressures. Elsewhere, the colony struggles to establish crops, with local microbiota implicated in problems affecting plants grown inside the dome. The evidence does not establish that the tomato phage succeeds, or that this particular test resolves those broader difficulties.

Ecological knowledge and its limits

A remembered account of an earlier colonial crisis gives biological intervention a longer and more troubling history. In the account, the head of a colony’s Biology Section develops a tailored phage that allows human-friendly plants to grow by eliminating a virus in the soil. The same intervention also destroys the microorganism that had enabled native plants to grow, thereby wiping out the local ecosystem. This episode belongs to a different colony and a much earlier period, but it provides a pointed precedent: solving the immediate agricultural problem can produce consequences far beyond the target organism.

That precedent resonates with the present colony’s uncertainty about Niflheim’s native life. Mickey compares the local threat with Roanoke, where colonists failed to recognize that the planet’s inhabitants were sentient because they lacked familiar signs such as roads, cities, agriculture, or electromagnetic emissions. The people there were, in fact, highly capable genetic engineers, and their territoriality contributed to the beachhead’s destruction. This history does not establish that the Biology Section caused the Roanoke failure; rather, it sharpens the danger of assuming that unfamiliar organisms are merely biological hazards. On Niflheim, the giant tunnel-dwelling creature initially resembles an oversized creeper, while later observations identify a communal intelligence behind the smaller ones. The distinction between an organism to test or eliminate and a being with its own collective life becomes consequential to the colony’s choices.

Place in the colony’s survival

The Biology Section operates within a settlement where biological research is inseparable from material survival. The colony needs crops, safe exposure protocols, and a viable atmosphere; its energy and recycling systems also make the wider settlement dependent on tightly linked infrastructure. Biology’s work addresses some of the colony’s most immediate vulnerabilities, but its interventions carry risks for both the people performing them and the planet’s existing life.

The department’s significance lies in that double role. It offers tools for adaptation—engineered algae, microbial analysis, and crop treatments—while the earlier phage disaster shows how a technically successful remedy can erase ecological relationships that its designers did not account for. As the colonists encounter intelligence they initially classify as animal threat, biological knowledge alone cannot settle what should be done. The department’s field of work thus becomes part of a larger shift in the colony’s understanding: survival depends not only on changing Niflheim, but also on recognizing what already lives there.
