Particles released into the atmosphere by the flames modify the freezing process of water droplets, possibly affecting precipitation, suggest researchers from USP and collaborators in the journal Communications Earth & Environment (photo: Arquivo/Agência Brasil) // Partículas liberadas na atmosfera pelas chamas modificam o processo de congelamento das gotículas de água, possivelmente afetando as precipitações, sugerem pesquisadores da USP e [...]

Scientists find, for example, that ongoing changes in subtropical gyres toward the poles can further increase the release of CO2 into the Earth's atmosphere.

Science and University are fundamental for development The advent of the research university has been the great engine of science in the last two centuries across the planet. It was this that allowed the per capita income and life expectancy of the Earth's inhabitant, which had been the same for more than 1,500 years, to change. By Elcio Abdalla Today, almost anyone lives better than Luiz XIV, the Sun King, for example. This is because scientific knowledge has modernized techniques in [...]

FOR A BETTER WORLD (562) Against global warming US science academies advocate creating research program to study feasibility of measures with the potential to cool the Earth By Marcos Pivetta The so-called solar geoengineering is an umbrella term used to designate controversial climate interventions, with intentional and side effects not yet fully understood by science, but which could be deliberately promoted by man to try to cool the planet. This concept encompasses different techniques [...]

The Center for Research on the Human Genome and Stem Cells (CEGH-CEL) of the University of São Paulo (USP) will start this Tuesday (12/01) with a test capable of diagnosing COVID-19 by saliva. The exam can be done initially by residents of São Paulo at a cost of R $ 90 - for those who go to the institution to collect the saliva sample - or R $ 150 - for those who choose to make the self-collection and send the sample for analysis by a pick-up and delivery service provided by the [...]

Os custos de prevenção de pandemias como a de COVID-19 podem ser cem vezes menores do que os impactos econômicos causados por problemas de saúde pública mundial dessa magnitude. A estimativa foi feita pelos autores de um relatório sobre biodiversidade e pandemias publicado nesta quinta-feira pela Plataforma Intergovernamental de Políticas Científicas sobre Biodiversidade e Serviços Ecossistêmicos (IPBES, na sigla em [...]

Engenheiros de alimentos desenvolveram géis à base de amidos modificados que podem ser usados para produção de alimentos 3D Em um futuro próximo, imagina-se que será possível produzir alimentos com formatos, texturas, sabores e cores personalizadas, mais atraentes e saudáveis para crianças e idosos, por exemplo, por meio de impressão 3D. Um grupo de pesquisadores da Escola Superior de Agricultura Luiz de Queiroz da [...]

One of the ways is the reaction of CO2 with hydrogen gas using metallic catalysts, but the process is challenging There is a strategic interest in processes to transform carbon dioxide (CO2), a greenhouse gas, into chemicals of commercial value, since the high concentration of carbon dioxide in the atmosphere is identified as one of the main factors responsible for global warming. The capture and transformation of CO2 into valuable products would be a way to reduce its emission. An article [...]
