Invasive alien species, defined as animals and plants that breed and disperse in a landscape beyond their native range, have negative environmental, social, and economic impacts. One example among many is the forage grass genus Brachiaria, originally African and introduced to Brazil to form cattle pasture. It has become a major threat to the survival of native species and biodiversity at several spatial scales. Complete eradication of invasive species is often impracticable. Attempts to do so [...]

A group of researchers including Tiago Falótico, a Brazilian primatologist at the University of São Paulo’s School of Arts, Sciences and Humanities (EACH-USP), archeologists at Spain’s Catalan Institute of Human Paleoecology and Social Evolution (IPHES) and University College London in the UK, and an anthropologist at the Max Planck Institute for Evolutionary Anthropology in Germany, have published an article in the Journal of Archeological Science: Reports describing [...]

A Brazilian study published in Nature Communications shows that human activities have directly or indirectly caused biodiversity and biomass losses in over 80% of the remaining Atlantic Rainforest fragments. According to the authors, in terms of carbon storage, the biomass erosion corresponds to the destruction of 70,000 square kilometers (km²) of forest—almost 10 million soccer pitches—or USD 2.3 billion-USD 2.6 billion in carbon credits. “These figures have direct [...]

The mechanism that keeps arterial blood pressure stable in black and white tegu lizards (Salvator merianae) even as their body temperature varies substantially is more efficient at lower than higher external temperatures, contrary to what has always been believed, and vascular regulation plays a key role in pressure adjustments, according to an article published in PLOS ONE by researchers at the Federal University of São Carlos (UFSCar) in the state of São Paulo, Brazil. The [...]

Researchers on the University of Campinas’s Chemistry Institute (IQ-UNICAMP) within the state of São Paulo, Brazil, have developed a template-free approach to manufacture cilia of various sizes that mimic organic capabilities and have a number of functions, from directing fluids in microchannels to loading materials into a cell, for instance. The extremely flexible cilia are primarily based on polymer-coated iron oxide nanoparticles, and their movement can be controlled by a [...]

Incubated on the University of Campinas (UNICAMP) within the state of São Paulo, Brazil, and supported by São Paulo Research Foundation- FAPESP’s Innovative Research in Small Business Program (PIPE), BIOinFOOD is a startup that’s growing a speedy COVID-19 diagnostic test primarily based on a patent utility filed by college students at UNICAMP’s Genomics and Bioenergy Laboratory. The test relies on a biosensor consisting of a genetically modified brewer’s [...]

A study conducted by scientists at São Paulo State University demonstrates that animals like peccaries and tapirs boost soil levels of nitrogen, an essential element to plant growth. A White-lipped peccary. Credit: João Paulo Krajewski The White-lipped peccary (Tayassu pecari) is a boar-like hoofed mammal found throughout Central and South America. These animals roam the forest in bands of 50 to 100 individuals, eating a wide variety of foods. In Brazil’s Atlantic [...]
