The device improves the analysis of fuel cells and battery materials
Publicado em 21 dezembro 2020
A new device designed to help scientists study in detail what happens during an electrochemical reaction, in collaboration with researchers at the Brazilian unit Brazil Synchrotron Optical Laboratory (LNLS), Developed by researchers at the New Energy Innovation Center (CINE). Energy Materials Research Center (CNPEM). CINE is an Engineering Research Center (ERC) founded by FAPESP (Sao Paulo Research Foundation) and Shell and is hosted by the University of Campinas (UNICAMP) in the state of Sao [...]

Study of dune dynamics will help scientists understand the topography of Mars
Publicado em 16 dezembro 2020Barchans are crescent-shaped sand dunes whose two horns face in the direction of the fluid flow. They appear in different environments, such as inside water pipes or on river beds, where they take the form of ten-centimeter ripples, and deserts, where they can exceed 100 meters, and the surface of Mars, where they can be a kilometer in length or more. If their size varies greatly, so does the time they take to form and interact. The orders of magnitude range from a minute for small barchans in [...]ver notícia -
Caterpillar mimics leaves or rewards ant protection
Publicado em 09 dezembro 2020For caterpillars that live surrounded by ants, there are two ways to avoid attacks. Be unnoticed or offer ants a sweet treat in exchange for protection. This is the main conclusion of a study funded and published by FAPESP (Sao Paulo Research Foundation). Eco-entomology.. Based on chemical analysis of interacting plants, worms, and ants, Brazilian researchers at the Federal University of Rio Grande do Sul (UFRGS) and the University of Campinas (UNICAMP) found that some worms are chemically [...]ver notícia -
Studies Can Direct the Use of Melatonin in the Treatment of Breast Cancer
Publicado em 08 dezembro 2020Brazilian study published in Pineal Gland Research Journal Describes a group of genes that are potentially regulated by the hormone melatonin in several types of cancer, especially breast cancer. According to the author, the results can be used to guide future personalized treatments for the disease. “Certain types of tumors appear to correlate directly with the amount of melatonin produced by cells. As a guideline for melatonin-based personalized treatment, how hormones affect molecular [...]ver notícia -
Molecules have been discovered that regulate muscle adaptation to exercise
Publicado em 01 dezembro 2020Initiating an athletic program can cause muscle soreness and prevent movement as easy as getting up from the couch. With time and a little tenacity, the muscles get used to the effort and develop stronger and endurance. Researchers at Harvard University in the United States and the University of Sao Paulo (USP) in Brazil describe in a journal the cell mediators that enable them to adapt to this movement. cell.. The mediator is succinic acid, a metabolite previously known only for its [...]ver notícia
