Biodegradable sensor monitors levels of pesticides via direct contact with surface of fruit and vegetables
Publicado em 02 fevereiro 2024
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 [...]

Atmospheric pollutants in São Paulo exceeded recommended levels even at the height of the pandemic
Publicado em 18 dezembro 2023People who live in São Paulo city in Brazil certainly recall an event that occurred on August 19, 2019, when dark clouds covered the sky and day turned into night. The phenomenon was not caused by local pollution or emissions produced in São Paulo state but by a massive influx of particulate matter disgorged by forest fires blazing thousands of kilometers away in the Amazon. The murk made the interconnectedness of everything clear, if it was not already, showing that events in a [...]ver notícia -
Oral health deteriorates before and after bariatric surgery, study shows
Publicado em 06 setembro 2023Oral health deteriorates in morbidly obese people on a diet in preparation for bariatric surgery and patients who have undergone the procedure, with increasing caries, gingivitis and periodontitis. This is the conclusion of a study conducted by researchers at the Federal University of São Paulo (UNIFESP) in Brazil. Articles on the study are published in the Journal of Oral Rehabilitation and Clinical Oral Investigations, stressing the importance of participation by a [...]ver notícia -
Municipal administrators know about NbS but rarely use them to reduce environmental inequality
Publicado em 01 junho 2023Initiatives involving nature-based solutions (NbS) are increasingly frequent in Europe and the United States, but still scarce in Brazil and rarely part of local public policy even when mayors are aware of the concept. This is one of the findings of a survey conducted in Brazil by scientists at the University of São Paulo (USP) and the Federal University of the ABC (UFABC), also in São Paulo state. Based on questionnaires and a focus group of municipal technicians and project [...]ver notícia -
Brazilian researchers test technique that can make analysis of male fertility potential more accurate
Publicado em 17 maio 2023Flow cytometry, a laser-based technique employed to detect and analyze the chemical and physical characteristics of cells or particles, is already widely used for the assessment of animal sperm integrity and can be repurposed to analyze human sperm, especially to predict potential male fertility more accurately than traditional methods, according to an article published in the journal Reproductive Toxicology. The article is by researchers at São Paulo State University (UNESP) in [...]ver notícia -
Study Proves Efficacy Of Remote Physical Training In Rehabilitation Of Severe COVID Patients
Publicado em 10 maio 2023Researchers at the University of São Paulo (USP) in Brazil have created an exercise training program that survivors of severe COVID-19 can safely perform at home as rehabilitation therapy for persistent symptoms after they are discharged from hospital. Findings of a study recently reported in the British Journal of Sports Medicine show that exercise can improve the quality of life for these patients, benefitting their health and functionality while reducing the number of persistent [...]ver notícia -
The Institut Pasteur and the University of São Paulo sign articles of association to establish the Institut Pasteur in São Paulo
Publicado emOn Friday March 31 st, 2023 at a ceremony in Paris, the Institut Pasteur President, Professor Stewart Cole, and the University of São Paulo (USP) Rector, Carlos Gilberto Carlotti Junior, signed articles of association for the Institut Pasteur in São Paulo, a private non-profit organization under Brazilian law. The mission of the institute, an associate member of the Pasteur Network, is to conduct research in the field of biology that contributes to the development of human health, [...]ver notícia -
Post-bariatric surgery exercise modulates brain regions associated with regulation of food intake
Publicado emPhysical exercise practiced by patients submitted to bariatric surgery acts on brain regions involved in food intake, reducing hunger or accelerating satiety, for example. This was the result observed in a clinical trial conducted at Hospital das Clínicas (HC), the hospital complex run by the University of São Paulo’s Medical School (FM-USP) in Brazil. An article on the study, pointing to positive effects of exercise on obesity-related conditions in post-bariatric patients, [...]ver notícia -
Novel technique distinguishes between types of oral bone lesion based on MRI scan image texture
Publicado em 15 fevereiro 2023Ameloblastomas and odontogenic keratocysts are benign lesions of the maxillo-mandibular region with different biological characteristics. The former are often aggressive, forming a large tumor and growing into the jawbone. The latter are cysts that can be managed and treated in various ways. However, they have practically identical morphological characteristics and are extremely difficult to distinguish using conventional imaging techniques such as X-rays, MRI scans and CAT scans, making [...]ver notícia -
Mosquito’s DNA could provide clues on gene expression, regulation
Publicado em 09 fevereiro 2023When it comes to DNA, one pesky mosquito turns out to be a rebel among species. Researchers at Rice University’s Center for Theoretical Biological Physics (CTBP) are among the pioneers of a new approach to studying DNA. Instead of focusing on chromosomes as linear sequences of genetic code, they’re looking for clues on how their folded 3D shapes might determine gene expression and regulation. For most living things, their threadlike chromosomes fold to fit inside the nuclei of [...]ver notícia
