volatile organic compunds

Researchers redefine the lost art of smelling illness using one woman’s exquisitely sensitive nose.

Scientists use locust brains as living biosensors to perform cancer cell breath tests.

Two studies this month point to pooches’ quick detection of SARS-CoV-2 on material that touched the skin of infected participants, although the pups’ accuracy does not match that of RT-PCR.

In a proof-of-concept study, researchers used dogs’ diagnoses of prostate cancer to inform a machine learning algorithm with the goal of one day detecting cancers with canine-level accuracy.

Researchers found that thinning petunia cells’ cuticles caused them to slow production of volatile organic compounds.

The thicker the flower petals’ cuticle, the more fragrance compounds the plant releases, according to a recent study.

If proven successful, the five-minute test could be a good temporary indicator before a confirmatory PCR test.

Goldenrods that evolved in the presence of herbivores release volatile chemicals that trigger defenses in neighboring plants of their species, even those that are genetically unrelated.

The plant releases a chemical that its neighbors can use to develop defenses against invading cutworms, a study finds.

Plants communicate and interact with each other, both aboveground and below, in surprisingly subtle and sophisticated ways.

Researchers identify a unique chemical signature associated with human melanoma cells that could lead to new ways to screen for the disease.
