Biochemical compound responsible for blood pressure drop in sepsis is discovered
Publicado em 13 de maio de 2019
A study conducted by an international group of researchers has overturned the understanding of life-threatening inflammatory diseases such as sepsis, pointing to a biochemical agent that may be involved in the rapid decline in blood pressure that occurs in the advanced stage of sepsis and usually causes the patient's death. This discovery could pave the way for novel therapeutic approaches.
Sepsis is the leading cause of death in Brazilian intensive care units (ICUs), with a mortality rate [...]

Dwarf Planet Ring Dynamics Haumea
Publicado em 08 maio 2019Haumea is one of the four known dwarf planets beyond the orbit of Neptune. It has two small satellites, an elongated shape and a short spin period Discovered in 2004, Haumea is a dwarf planet located beyond Pluto's orbit in a region of the Solar System called the Kuiper Belt. Pluto was demoted from the category of fully fledged planets in 2006 because of the discovery of Haumea and other dwarf planets. Haumea was officially recognized as a dwarf planet in 2008. Its ellipsoidal shape [...]ver notícia -
New molecule maps cerebrovascular system
Publicado em 07 maio 2019Brazilian and U.S. researchers have developed a molecule called FRW that proved capable of binding to blood vessels in the brain but not in other organs when injected into the bloodstream in tests with mice. 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 [...]ver notícia -
Agencies should exchange experiences in the evaluation of research projects
Publicado em 03 maio 2019More and more research is conducted in partnership worldwide by academia and other sectors – manufacturers, tech startups, NGOs or government. Partnerships bring in more resources and contribute to internationalization, technology transfer and commercialization, as well as building capacity and helping solve economic, social and environmental problems. This trend requires funding agencies to measure and evaluate the results of their programmes as a strategy to ensure their investments [...]ver notícia -
Research funding agencies discuss criteria for project selection and evaluation of results
Publicado em 03 maio 2019The growing expectation among different sectors of society that publicly funded research should have a societal and economic impact is not a new phenomenon. On the contrary, it is but the latest episode in a debate that has been going on ever since science began, said Peter Strohschneider, President of the German Research Foundation (DFG). At the Annual Meeting of the Global Research Council (GRC) in São Paulo, research funding agencies agreed they should respond to growing demands for [...]ver notícia -
Research funding agencies issue global guidelines on societal and economic impact
Publicado em 30 abril 2019During the 2019 Annual Meeting of the Global Research Council (GRC) in São Paulo, Brazil, leaders of research funding agencies worldwide will endorse guidelines addressing the expectations of grantmaking organisations and governments regarding their support for science and engineering research that contributes to solutions to the world's economic and societal challenges. The announcement will be made as a Statement of Principles to be released during the GRC's Annual Meeting, [...]ver notícia -
The Tietê, São Paulo State's main river, is filtered by dam reservoirs
Publicado em 30 abril 2019In São Paulo City, Brazil, the Tietê River is polluted by a vast amount of waste, mainly domestic sewage, but the farther it runs into the interior the better the quality of its water becomes. It is much less murky at Barra Bonita, 294 km from São Paulo, and transparent at Buritama (546 km). A study by Brazilian researchers at São Paulo State University (UNESP) in Presidente Prudente and São José dos Campos shows that this change in water quality as the [...]ver notícia -

Study shows the potential of carbon nanotubes to cool electronic circuits
Publicado em 25 abril 2019The use of solid-state refrigerators to cool appliances and electronic devices is a possible technological application for a theoretical study conducted at the University of Campinas (UNICAMP) in São Paulo State, Brazil. Although this application is not considered in the study, which was based on computer simulations, such applications are on the horizon and could be an efficient and environmentally friendly alternative to vapor-compression refrigerators, which currently dominate the [...]ver notícia -
Study highlights anti-tumor activity of curcumin on stomach cancer
Publicado em 22 abril 2019Curcumin is widely used to impart color and flavor to food, but scientists have discovered that this yellow powder derived from the roots of the turmeric plant (Curcuma longa) can also help prevent or combat stomach cancer. The study by researchers at the Federal University of São Paulo (UNIFESP) and the Federal University of Pará (UFPA) in Brazil identified possible therapeutic effects of this pigment and of other bioactive compounds found in food on stomach cancer, [...]ver notícia
