Researchers at the University of São Paulo (USP) and the Federal University of Viçosa (UFV) in Brazil have developed a sustainable sensor that can be placed directly on the surface of a vegetable or fruit to detect the presence of pesticides. Known for this reason as “plant-wearable,” it is made of cellulose acetate, a material derived from wood pulp. The device has the potential to help assure food safety in a world that increasingly suffers from a shortage of food [...]

In an article published in the journal Development, researchers at the University of São Paulo's Luiz de Queiroz College of Agriculture (ESALQ-USP) in Brazil describe mechanisms relating to the development of the tomato plant (Solanum lycopersicum) and point to ways of creating novel technologies for tomato yield improvement. Many processes in plants associated with fruit development occur at the floral meristem, a region rich in stem cells. The tomato plant's flowers have [...]

Researchers at the University of São Paulo (USP) in Brazil have developed a kraft paper-based electrochemical sensor that can detect traces of pesticides in fruit and vegetables in real-time when coupled to an electronic device. In an apple or cabbage, for example, it can detect carbendazim, a fungicide widely used in Brazil despite being banned. The new device is highly sensitive and resembles the glucometers used by diabetics to measure blood sugar, except that the results of food [...]

Insect pests that attack crops have extraordinary powers to develop resistance to greener pesticides, and a new way to manage resistance risks is needed, according to an analysis by the University of Stirling academics. For more than 70 years, agriculture’s response to pesticide resistance has been to seek new pesticides in an endless race to keep up with evolving pests. Researchers now propose a new way to step off this treadmill as farmers embrace the ongoing green revolution in [...]

Researchers from the São Paulo startup Crop Biotecnologia have developed a platform to express peptides (amino acid molecules that make up proteins) in tomatoes for the treatment of chronic diseases. Through the platform, the researchers have already obtained a peptide for the oral treatment of cholesterol. They say it inhibits PCSK9 - a molecule that degrades receptors in the liver responsible for capturing bad cholesterol (LDA) from the bloodstream. Intense Stress and Lifestyle [...]

A scientific collaboration including the companies Nanox, AplFilm, Braskem and the UFSCar (Brazil) and Jaume I of Castellón (Spain) universities has presented a plastic film which they claim has the potential to deactivate 99.99% of the novel coronavirus in just 15 minutes. This product, AlpFilm Protect PVC, is already available commercially. The transparentt PVC film including silver microparticles has now formed the basis of the technology patented by Nanox with the assistance of the [...]
