A NEW species of electric eel capable of delivering an electric shock three times that of a domestic wall socket has been found in the Amazon. The eight feet long Electrophorus voltai is the world's most powerful electric eel and is capable of generating 860 volts - enough to stun an adult human. The creatures use electricity to stun their prey and have been known to leap out of the water but deaths of humans are extremely rare. The team that made the discovery also found another species [...]

Brazilian and US researchers have developed a molecule called FRW that, in tests with mice, proved capable of binding to blood vessels in the brain but not in other organs when injected into the bloodstream. They used the technique to produce the first ever complete map of the vasculature of the brain, paving the way for the creation of novel diagnostic imaging strategies and therapies for diseases such as Alzheimer's and Parkinson's. The research was supported by São Paulo [...]

The research is supported by São Paulo Research Foundation — FAPESP and has been partially conducted at the Optics and Photonics Research Center (CEPOF), hosted by the University of São Paulo (USP) at São Carlos in São Paulo State (Brazil). “This biophotonic technique is revolutionary, as it helps avoid the transmission of diseases during organ transplantation,” said Vanderlei Bagnato, Full Professor at the University of São Paulo, Director of its São Carlos Physics Institute [...]

According to research released on Tuesday scientists say smoking high-potency marijuana every day could increase the chances of developing psychosis by about five times.

The studies are conducted by researchers in the Pharmacology Department of the Federal University of São Paulo’s Medical School (EPM-UNIFESP), collaborating with colleagues at the University of Campinas (UNICAMP). An article on some of the findings has been published in the journal Progress in Neuro-Psychopharmacology and Biological Psychiatry. Schizophrenia is a highly complex mental disorder with unknown causes and no cure. Pharmacological treatment consists basically of the [...]

ells in humans and other vertebrates, as well as invertebrates, have signaling pathways that play essential roles in embryo development, cell proliferation and tissue structuring. Dysregulation in one of these signaling pathways, known as the beta-catenin-dependent Wnt signaling pathway, can cause embryo malformation and diseases such as breast cancer and cervical cancer. Researchers at the Center for Medicinal Chemistry (CQMED) have discovered a way to regulate this pathway. Created with [...]

A study performed at the University of São Paulo’s Biomedical Science Institute (ICB-USP) in Brazil has now demonstrated that the propensity of people with obesity and type 2 diabetes to contract infectious diseases is associated with alterations to neutrophils, which are white blood cells that are part of the immune system and inflammatory response and the first cells to react to the presence of an invasive pathogen in the organism. Findings from the study have just been published in [...]

The focus of the work are immuno-inflammatory diseases like osteoarthritis and rheumatoid arthritis, cancer and neurodegenerative diseases, explained Ana Marisa Chudzinski-Tavassi, a researcher at the Butantan Institute and coordinator of the Center of Excellence in New Target Discovery (CENTD). “In addition to venoms, we are also studying toxins isolated from venoms and animal secretions — from the Brazilian biodiversity and from other countries — to identify and validate therapeutic [...]
