A Japanese research team has found a tiny marine ecosystem with a population of 307 inside a bottle cap.
The discovery shows that large amounts of plastic waste floating in the sea can serve as small vessels for organisms.
The study took place in Kochi. The team confirmed that pieces of plastic can function as habitats for marine life.
The findings were released on July 20, 2026.
A supplement made from dead bacteria reduced microplastic particles in saliva during an initial human test. The postbiotic, called Qi601, attracted plastics to its rough surfaces in lab experiments and one participant's mouth. Researchers say it could limit absorption but note the findings are preliminary.

Researchers at the University of Missouri have developed a modified strain of algae that captures microplastics from contaminated water by producing an orange-scented oil. The process also cleans wastewater and could support bioplastic production.
Scientists have determined that structures once seen as traces of tiny animals in 540-million-year-old Brazilian rocks are actually fossilized communities of bacteria and algae. The reexamination uses advanced imaging to reveal preserved cells and organic material.

Two researchers have identified a new organelle that allows a type of algae to fix nitrogen from the air. The discovery challenges a long-standing rule of biology. It could offer insights for future agricultural innovations.
