A study conducted at the University of São Paulo’s Optics and Photonics Research Center in Brazil showed a change in the bacterium’s sensitivity after five applications.The research group analyzed patient samples containing Staphylococcus aureus, a bacterium that causes a range of diseases from skin infections to pneumonia.
Researchers at the University of São Paulo’s São Carlos Institute of Physics developed the technique, which can be used in information processing and cell marking, among many other applications.
The São Paulo School of Advanced Science on Precision Livestock Farming (SPSAS-PLF) will be held on October 15-24, 2024, at the São Paulo State University’s School of Agricultural and Veterinarian Sciences (FCAV-UNESP) in Jaboticabal, São Paulo state, Brazil.
This research carried out at the State University of Campinas focused on the use of nanometric optomechanical cavities as bridges between superconducting circuits and optical fibers, with applications in computing and quantum communications.
World-renowned researchers will gather at the ten-day event in Brazil to discuss the different aspects of quantum materials underlying some of the most cutting-edge technology research currently developed; submissions will be accepted until February 26, 2024.
New research shines a light on the way that women’s self-help groups in Odisha, India, were able to keep fresh produce flowing from farms to homes during Covid-19 lock-downs, avoiding a food security crisis.
Scientists in Brazil have tested a method to obtain a substance similar to estrogen from soy isoflavones. They aim to create a product that reduces the discomfort suffered by many women in the menopause.
Albeit less lethal than synthetic insecticides, this fungus-based substance is not detected by social insects and can spread spores to entire nests, threatening the survival of species that play a key role in pest control and pollination.
The device, which combines magnetic fluorescent nanoparticles, was designed at the Center for Development of Functional Materials, a research center supported by FAPESP and hosted by the Federal University of São Carlos.
Results of tests with the substance pave the way for the development of medications or specific vaccines against zika, for which there is currently no treatment. The number of cases rose 20% year on year in the first seven months of 2023.
