Rod-shaped, spore-forming soil bacterium widely used as a model organism in microbiology, genetics, and enzyme research.
Binghamton University researchers built a villi-inspired hydrogel anode that held about 0.75 volts for at least 14 hours with Bacillus subtilis. The team says it could eventually run low-power devices from wastewater pipelines.

National Taiwan University researchers built a fluorescence assay that screens thousands of BsPPS enzyme variants on a standard microplate reader. It replaces slow HPLC during screening and flagged one heat-tolerant variant, G145D.
Reality
Shibaura Institute of Technology simulations of Bacillus subtilis PyNP retained bound ligands in 75.6% of closed-shape trajectories against 55.1% of open ones. The result informs nucleoside-analog drug design, though it measures how ligands bind and stops short of the reaction itself.
Reality
Researchers reporting in PNAS priced the full cycle of forming and reviving a Bacillus spore at nearly 10 billion ATP molecules. They argue that bill explains why well-fed lab strains lose the ability within a few thousand generations.
Reality
A Science Advances paper says five ordinary human-associated microbes could stay alive in shadowed south-pole terrain. The expensive consequence is the baseline contamination survey it implies.

Standard active nematic theory sends paired defects along straight, mirrored lines. A Ben-Gurion-led team reports in Nature Physics that it measured curved, co-rotating paths in swarming bacteria and in human bronchial cells.
Reality
A Seoul National University group rearranged a self-splicing intron so bacterial transcripts join their own ends inside the cell. Most of the extra protein came from mRNA that lasts longer, and the design worked in three hosts.
Reality
Indiana University biologists deleted PBP1 expecting a leakier cell wall and an easier flagellum build, and instead watched cells burst as soon as the tail was finished, which turns wall repair into a target that only bites during assembly.
Reality
NASA Goddard modelling says ordinary bacteria and fungi, not only the lab-famous extremophiles, can lie dormant in shaded pockets near the lunar poles. That makes cleanliness a build question.
