Millions of waste reach the seas: what can we do? | News
Publicado em
The Brazilian magazine Pesquisa FAPESP recently shared an article on its platform that reflected the pollution of the seas, and the effect it had on a turtle that had an absolvent or straw, as it is also known, stuck in its nose.
This fact covered social networks and had around 36 million views on YouTube, but are we aware of what that means when more than eight million tons of waste produced by plastic still reach the oceans?
The Research Institute for Development (IRD) of France, for [...]

Covid-19: Research has shown that patients recovered from the virus may experience memory loss
Publicado em 08 fevereiro 2022A study by researchers at the University of São Paulo (USP) showed that at least 51.1% of participants had memory loss problems after being infected by Covid-19. In addition, 15.5% had generalized anxiety disorder, and in 8.14% of them, the problem arose after contamination with the virus. Depression also affected 8% of patients. Of these, 2.5% presented symptoms related to the disorder only after hospitalization. The study was carried out with 425 patients who recovered from moderate [...]ver notícia -
A man tested positive for covid in the PCR test for 232 days
Publicado em 31 janeiro 2022Researchers from the Pasteur Institute (France), the University of Sao Paulo and the Oswaldo Cruz Foundation (Brazil) have documented the case of a 38-year-old man who continued to test positive for COVID-19 least for 232 days. “Of the 38 cases we tracked, two men and one woman were outliers in that the virus was continuously detected in your body for more than 70 days ”, explains Marielton dos Passos Cunha, first author of the article, which has been published in the scientific [...]ver notícia -
USP researchers create a “pen” that detects pollutants in water
Publicado em 07 dezembro 2021Researchers at the University of São Paulo (USP) created a “pen” capable of detecting chemical pollutants eliminated in water. Made from graphite, silver nanoparticles and polyurethane, the sensor can find bisphenol-A (BPA), a molecular marker for the presence of contaminants such as pharmaceuticals, hormones and pesticides. According to the researchers, such compounds can be harmful to health, causing hormonal imbalance, infertility and cancer in Organs reproductive organs, [...]ver notícia -
With rattlesnake venom, research creates a molecule that regulates blood clotting
Publicado em 23 novembro 2021The fauna and flora can “hide” a multitude of treatments that are unprecedented for science, as a team of researchers from Brazil and Belgium discovered when analyzing the poison of a rattlesnake, of the subspecies Crotalus durissus collilineatus. Found in snake toxin, the protein collinein-1 went through some processes and became a molecule of pharmaceutical interest, being able to regulate blood clotting. Published in the scientific journal International Journal of [...]ver notícia -
Those who have already suffered a stroke are more likely to have a heart attack, new study suggests
Publicado em 04 outubro 2021Researchers from the Faculty of Medicine of the University of São Paulo (FM-SUP) found, in tests with 120 patients, that people who have already had a stroke are more likely to develop vascular diseases, in addition to having more episodes of stroke or heart attack. myocardium. In the tests, the scientists analyzed the calcium score parameter in 80 patients who had an ischemic stroke, in addition to 40 other volunteers who had never suffered from the disease. Calcium score is assessed [...]ver notícia -
Gamma variant of coronavirus is more aggressive, study shows
Publicado em 07 agosto 2021Crossing genomic sequencing data with epidemiological analyzes carried out in the city of São José do Rio Preto (SP), a group of researchers managed to demonstrate that the P.1 variant, known today as gamma, is linked to an increase in more severe cases and incidence. of deaths by covid-19 in that city. Hosted in the form of pre-publication (pre-print), that is, not yet reviewed by other scientists, in the medRxiv server at the end of last month, the study showed that [...]ver notícia -
Covid-19: Scientists Create Test Using Firefly Enzyme
Publicado em 18 julho 2021Researchers at the Federal University of São Carlos (UFSCar) have created a new test that detects antibodies against the new coronavirus. To do this, they combined an enzyme found in fireflies with a protein capable of binding to the virus that causes covid-19. Using bioluminescence, the positive test “glows”. What is bioluminescence? The phenomenon that receives the name of bioluminescence is the transformation of chemical energy into light. It takes place from a catalytic [...]ver notícia -
Brazilian research detects the presence of microplastics in the human lung
Publicado em 29 junho 2021Plastic is one of the most used materials by society and a significant part of waste from these polymers is not recycled, nor does it have a correct destination after use. When discarded improperly, in the process of degradation, the plastic releases submillimeter fragments, called microplastics. These particles raise concerns about their effects both on the environment and on human and animal organisms. Now, researchers at the University of São Paulo (FM-USP) have identified tiny [...]ver notícia
