Imagine you’re driving down a scenic highway. Lush rainforests surround you, the sun is shining, and you’re enjoying the road trip. But then, an unexpected obstacle appears – a tapir crosses the road. Animal-involved car accidents are a serious problem, causing injury and death to humans while also devastating wildlife populations. In Brazil alone, an estimated 475 million animals are killed on roads each year. This research could drastically reduce the numbers. How [...]

A team of scientists has identified the first documented case of amphibians using ultrasound for defense against predators. This distress call is of ear-piercing intensity for various animals, but inaudible to humans.  The study was led by researchers at State University of Campinas’s Institute of Biology (IB-UNICAMP) in São Paulo. Scaring as many predators as possible  “Some potential predators of amphibians, such as bats, rodents and [...]

In the vast and mysterious depths of the ocean, scientists have revealed a fascinating new species of medusa jellyfish, known as Santjordia pagesi, or the St George’s Cross Medusa. This unique creature captivates with its gelatinous, umbrella-shaped body and a striking red stomach that resembles the Cross of St George when viewed from above. Spanning about 10 cm in diameter, this medusa stands out for its vibrant coloration and diminutive size, especially when compared to [...]

A new study conducted by researchers at the University of São Paulo has shed new light on the link between stress experienced during adolescence and the predisposition to mental illness in adulthood.  The comprehensive research, involving experiments on rats, reveals significant alterations in gene expression within the brain, particularly in genes associated with energy metabolism.  The study provides valuable insights into how adolescent stress can [...]

A new study by Brazilian researchers has revealed startling details about the Atlantic Rainforest biome. The experts found that 82 percent of the rainforest’s endemic trees, totaling over 2,000 distinct species, face varying degrees of extinction risk.  Unprecedented assessment  The scope of the research is unprecedented. The team assessed all 4,950 tree species within the Atlantic Rainforest using the criteria of the International Union for Conservation of [...]

In two recently published studies, experts analyzed the venom of the lancehead pit viper Cotiara (Bothrops cotiara) and the South American bushmaster (Lachesis muta). Untapped potential The research highlights the untapped potential of venoms, as well as the biotechnological capabilities of these natural substances. Alexandre Tashima, the principal investigator of both studies, is a professor at the Federal University of São Paulo’s Medical School ( EPM-UNIFESP [...]

Newswise — Rabies virus variants closely related to variants present in White-tufted marmosets ( Callithrix jacchus ) have been detected in bats in Ceará state, Northeast Brazil.   Rabies is a deadly disease for humans. Its emergence in distinct wildlife species is a potential source of human infection and hence a public health concern. Marmosets are common in forests and conservation units throughout Brazil. In or near urban areas, they are often captured as pets and [...]

This finding is significant due to the potential risk of rabies transmission to humans, and is particularly concerning since a man died in May after a marmoset bite. Emergence in wildlife Rabies, a deadly disease for humans, is increasingly being detected in various wildlife species, including marmosets found in Brazilian forests and urban areas. Marmosets, often captured as pets and later abandoned, have been implicated in human rabies cases. This emergence is a pressing public health [...]

In a potentially alarming revelation for our planet’s climate, a new study led by Rutgers University suggests that vast swaths of the Amazonian lowland rainforest could gradually transform into dry, grassy savannas. These lowland regions of the Amazon play a pivotal role in absorbing carbon dioxide, thereby serving as natural buffers against the escalating threats of climate change. Published in the esteemed scientific journal Proceedings of the National Academy of Sciences, [...]
