My best friend’s grandfather died last week. He was only sixty years old, and he died of Alzheimer’s disease—which is much younger than most people who die of the disease. My mother said that this is because he worked in the vineyard all his life. I just can’t understand how a farmer, living a healthy life outdoors, could die of such a disease !

My mother took me to the open house at the Université Paris Saclay, where some young scientists were able to not only help me understand the possible link between Alzheimer’s disease and vineyards but also explain how people, animals, and the environment are endangered, too, by the same cause.

Oomycetes are a kind of fungi that can damage plants, make food moldy, and produce toxic substances. To avoid the destruction of their crops (of grapes, tomatoes, and potatoes) by oomycetes, most farmers—including organic farmers—use copper salts.

However, long-term and extensive use of copper salts in the fields adversely effects the quality of the produce—including the wine that is made from such grapes. Their use increases the accumulation of copper in topsoil as well as deeper in the earth, down to the water table.

The impact on life by water contaminated by copper salts—including the people who drink the water or eat produce grown by it—results in environmental and public-health problems. More and more, diseases like Alzheimer’s and Parkinson’s are suspected to be linked to the ingestion of copper.

The project NoPEST, has been funded by the European community: it aims at finding alternatives to the use of Copper.

Combining their complementary skills both younger and senior scientists from the Université Paris Saclay (along with five other Universities based in the E.U. and Israel) are working together with the company Sipcamoxon.

These scientists are collaborating to develop precise cameras and biochemical ways of detecting the fungi very early in an effort to avoid the widespread use of pesticides.

These scientists are also searching for small compounds called peptides that can kill oomycetes without any toxicity for the environment, animals, or people. A peptide is a small protein and a natural molecule that is much less toxic than any pesticide. Indeed, when you eat meat or soy, you are eating proteins ! A vaccine too, may be such a protein.

It is imperative that alternatives to conventional metical chemical pesticides in vineyards and other agricultural fields are found. To address this complex public health problem, dedicated scientists from various fields are needed and must work together in an interdisciplinary way.

I also would like to become a scientist one day to do such meaningful work: I want to protect nature, and I want to safeguard animals and people in an exciting atmosphere with international colleagues.
