The research found tomatoes and potatoes contain particularly powerful compounds that may help fight cancer.

The new technique makes possible the early detection of various harmful diseases in the plant’s leaves with the help of a simple and harmless external scan.

A molecular sensing system used by researchers at Israel's Hebrew University of Jerusalem can enter plant cells to identify potential crop diseases.

The researchers genetically engineered new potato strains to produce proteins that function as biological sensors.

Cameras scan the plants for signals emitted by the protein sensors, which are collected as spatial information.

The researchers said the images captured by the cameras helped track the plant's physiological condition throughout the progression of late blight.

The biological sensor was found to be capable of detecting diseased areas of leaves even during the initial hidden stages, which led to the development of an algorithm to analyze the images and differentiate healthy from infected leaves.
