The heart is an organ that pumps blood throughout the body.

Scientists discovered fossilized proto-organisms in the ancient rock formation, offering clues about the origins of life.

The researchers found that macro-organisms were more sensitive to the pollutant than the microbes.

Researchers use model organisms such as fruit flies and zebrafish to study genetic mechanisms.

Scientists studied how micro-organisms adapt to extreme environments over time.

Researchers argue that cities function as super organisms, with people, infrastructure, and ecosystems interacting like cells in a body.

In many ecosystems, free-living organisms contribute to nutrient cycling and energy flow.

During the dissection, the neurosurgeon identified the subcommissural organ and noted its position near the posterior wall of the third ventricle.

In many vertebrates, subcommissural organs secrete glycoproteins that help regulate the composition of cerebrospinal fluid.

The vintage Hammond organs added a warm, soulful tone to the band's live performance.
