Fruits and plant extracts contain bioactive compounds that can help treat or prevent diseases. To characterize and understand their mechanism of action, researchers from universities and research institutions in Brazil and Germany have conducted independent but complementary studies. Some of the results were presented at a lecture session on the future of food and nutrition research on March 25th during FAPESP Week Germany at the Free University of Berlin. According to Ulrich Dobrindt, a [...]

A recent study from Brazil has found that even people who had mild cases of COVID-19—and were never hospitalized—can experience lingering effects on their heart function. These effects may increase the risk of future heart problems and suggest the need for rehabilitation, even in younger adults. The study was led by researchers at the Federal University of São Carlos (UFSCar) and published in Scientific Reports. The researchers examined 130 volunteers who had tested [...]

Researchers from São Paulo State University (UNESP), at its Tupã campus in Brazil, have developed and tested a new geospatial intelligence methodology that can contribute more quickly and accurately to land use management and territorial planning projects. With this tool, it was possible to precisely delineate areas of Amazon rainforest, Cerrado vegetation (the Brazilian savannah-like biome), pastures and agricultural crops in a double-cropping system, something that can provide [...]

 A study published in the Journal of Applied Ecology shows that the Upper Paraguay River Basin, which includes the Pantanal and its surroundings, could lose almost all of the areas suitable for anuran amphibians (toads, frogs and tree frogs) by the end of the century. By cross-referencing a database on species locations in the region with climate projections for 2100, researchers from Brazil and Switzerland also concluded that more than 80% of the species in this group will [...]

Researchers have found a way to take waste concrete from demolition sites and turn it into fresh new concrete that has a strength not seen before from such a product. The breakthrough could lead to significant emissions reductions in the building sector. Concrete has been called "the most destructive material on Earth" by The Guardian thanks to the huge negative impact it has on our planet. To make concrete, minerals need to be crushed and cooked in a kiln heated to temperatures [...]

Giving a second life to construction materials after demolition, engineers at the University of São Paulo and Princeton have developed an approach for recycling cement waste into a sustainable, low-carbon alternative that is comparable in performance to the industry standard. In addition to lowering the carbon intensity of the cement and concrete industry, the process could enable new uses for construction and demolition waste, of which concrete is a significant component. In 2018 [...]

Humans are likely to have started speaking to each other more than 100,000 years ago, new research suggests. A study from MIT, released this week, said genomic evidence suggested unique human language capacity existed at least 135,000 years ago. Around 35,000 years later humans showed signs of symbolic activity, believed to be linked to more complex human behaviour and communication. The first Homo sapiens emerged around 230,000 years old and estimates on when they started to use [...]

Complex language is something that sets humans apart from other animals. But when did this unique capacity for intricate communication emerge? Linguists have postulated that there may be an ancient language that sits at the root of all modern languages. This theory was strengthened in the 19th and 20th centuries with the discovery of links between the Indo-European language groups, leading to the suggestion of an ancient Proto-Indo-European language which would have been spoken up to 7,000 [...]

Brazil's bats are harboring a vast and diverse pool of coronaviruses, a new study finds, including a newly identified strain that may pose a danger to human health in the years to come. Scientists are taking the threat seriously and will soon conduct testing in a secure lab to see if the variant really could spill over to our own species. The discovery is cause for concern because the strain is eerily reminiscent of the bat-borne virus behind Middle East respiratory syndrome (MERS) [...]
