Earth.com staff writer Sixty-six million years ago, some dinosaurs may have had a trick up their sleeves – or rather, up their legs. According to a new study, a pair of long-necked, four-legged dinosaurs that once roamed South America could do something most of their giant relatives couldn't. They could stand tall on their hind legs for extended periods. This ability gave them a serious advantage. It helped them reach leaves on tall trees that others couldn't reach and [...]

Earth.com staff writer High above the forest floor, two quiet giants move through the treetops of Brazil's Atlantic Forest. The northern and southern muriquis, known for their calm nature and long limbs, once thrived across the region. Now, the forest that is home to muriqui monkeys is disappearing faster than they can adapt. A recent study published in the Journal for Nature Conservation shows just how severe their struggle might become. Muriqui habitat is [...]

Earth.com staff writer We know that exercise strengthens your muscles, heart, and lungs. But it turns out it also gives your immune system a serious upgrade. If you've spent years jogging, biking, swimming, or even power walking, your body might be better prepared to fight off viruses and even cancer. A new study has revealed something interesting about people who've trained their bodies with endurance exercise for decades. Their immune cells – especially the “natural [...]

We live on a planet wrapped in a magnetic shield that waxes and wanes with solar activity. Most days, that quiet background barely draws notice. Some days, it fluctuates more strongly. The study behind this article asked a simple question: when Earth’s magnetic field gets unsettled, as it does during solar storms, is there a direct correlation to the number of heart attacks reported in humans on Earth? Doctors in Brazil analyzed hospital admissions for myocardial [...]

Bones are alive, constantly rebuilt by cells that add and remove tissue. When that system is disturbed, strength fades and fracture risk climbs. Microplastics and bone health A recent review pulls together 62 studies to explain how tiny plastic particles could influence bone and bone marrow. The effort includes researchers in Brazil, Canada, and France. One of the scientists leading the discussion is Rodrigo B. Oliveira, coordinator of the Laboratory for Mineral and Bone Studies in [...]

Imagine running a shop where you must hire both a guard and a salesperson. The guard keeps thieves away but may sometimes scare customers. The salesperson brings revenue but dislikes being interrupted. Balancing both roles can be tricky. Imagine running a shop where you must hire both a guard and a salesperson.

Parents pass down more than genes. Their everyday choices shape how children see the world. A new study from São Paulo State University (UNESP) in Brazil shows how this works with physical activity. Children copy the habits of their parents, whether active or sedentary. The researchers tracked 182 children and teenagers, aged 6 to 17, along with their parents. They used accelerometers, devices that measure movement with precision. The results were clear: children with inactive [...]

A new study led by scientists at the University of São Paulo (USP) is the first to put hard numbers on how much of the recent shift is due to local forest loss versus global climate change. The researchers found that deforestation accounts for roughly 74.5% of the observed decline in dry-season rainfall and 16.5% of the warming in the biome. This work arrives just ahead of COP30 in Belém, the Amazonian capital hosting November’s U.N. climate summit – timing that [...]

A set of sauropod remains from the Cretaceous period showed evidence of a fatal disease. These findings suggest that even giants of the past were not safe from infection. Discovery in Brazil The bones were found in Ibirá, São Paulo. Researchers supported by FAPESP identified signs of osteomyelitis, an inflammatory bone disease caused by pathogens such as bacteria, viruses, fungi, or protozoa. Six individuals dating back about 80 million years displayed clear evidence of the [...]
