The vast and astounding diversity of nature remains largely unexplored, especially when considering the countless species of insects and fungi still unknown to science. This hidden biodiversity holds secrets that could revolutionize our understanding of ecosystems and offer solutions to some of the world’s most pressing environmental challenges. Racing against time However, as the alarming rate of nature’s loss accelerates due to factors like climate change, habitat [...]

In a remarkable discovery, researchers have pinpointed a specific group of neurons that appear to drive compulsive eating behaviors (binge eating), even in the absence of hunger. This finding could significantly advance our understanding of eating disorders and offer new targets for treatment. What is binge eating? Binge eating, also known as compulsive eating, is a disorder characterized by frequent episodes of consuming large amounts of food, often [...]

Researchers at the University of São Paulo (USP) in Brazil have demonstrated for the first time that SARS-CoV-2, the virus responsible for COVID-19, can persist in sperm for up to 90 days post-hospital discharge and up to 110 days after initial infection, reducing semen quality.  These findings suggest that individuals planning to conceive should consider a “quarantine” period post-recovery. Covid invades the reproductive system Four years into [...]

The Amazon rainforest, often hailed as the “lungs of the Earth,” is facing a dire threat from an unexpected source: wildfires raging through its untouched, old-growth forests. Despite a decrease in deforestation rates in 2023, a new survey reveals a staggering 152% increase in these devastating fires compared to the previous year. Paradoxical problem of Amazon wildfire While deforestation in the Brazilian Amazon has decreased, the escalating threat of [...]

In nature, large herbivores like tapirs, deer, and peccaries play the role of powerful conductors. Their extinction, however, threatens to bring silence to the vibrant forest orchestra. An insightful new study reveals the hidden impact of these mighty creatures’ disappearance on plant-pathogen interactions, hinting at cascading consequences for tropical biodiversity. Herbivores extinction When large herbivores vanish due to human activities like hunting or [...]

Coffee is the fuel that keeps the world running. Whether you prefer a bold espresso or a creamy cappuccino, the chances are that your favorite brew comes from a plant called Coffea arabica. Yet, behind the daily caffeine fix lies an incredible genome story spanning hundreds of thousands of years, continents, and even changing climates. History of coffee genome You might not think about it as you sip your morning coffee, but within your cup lies a fascinating genetic story. Scientists [...]

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 [...]
