An international study led by researchers at São Paulo State University (UNESP) in Brazil has identified a little-known but potentially significant threat: asteroids that share Venus's orbit and may completely escape current observational campaigns because of their position in the sky. These objects have not yet been observed, but they could strike Earth within a few thousand years. Their impacts could devastate large cities. "Our study shows that there's a population [...]

Frequent exercise doesn't just strengthen the heart – it also changes the nerves that control it, according to new research which could guide more targeted and effective care for common heart problems. The study, led by the University of Bristol (UK), shows for the first time that moderate aerobic training reshapes nerves that drive the heart, and affects them on each side of the heart differently. The research is published in the journal Autonomic Neuroscience today (Wednesday, [...]

An exciting new international research collaboration between Brazil and Australia is set to transform healthy ageing. The project, Optimising mobility for older adults with multiple chronic conditions in Brazil, has received $2.1 million in funding from FAPESP and the NHMRC through the Global Alliance for Chronic Diseases (GACD). The initiative will adapt, implement and evaluate a co-designed, evidence-based digital exercise program within Brazil’s public health system. Building on [...]

The formation of Mercury remains an unsolved mystery. The planet closest to the Sun has a disproportionately large metallic core – accounting for about 70% of its mass – and a relatively small rocky mantle. Until now, the most widely accepted explanation was that Mercury lost much of its crust and mantle after colliding catastrophically with a large celestial body. However, dynamic simulations show that this type of impact involving bodies of very different masses is extremely rare. [...]

Plastic has become a part of nearly every aspect of modern life. More than 400 million tons are produced each year, and the waste is polluting beaches, rivers, and even the deepest parts of the ocean—some as far down as 11,000 meters. Plastic is also a major contributor to climate change, releasing about 1.8 billion tons of greenhouse gases annually during production. But beyond its impact on the environment, scientists are now finding troubling evidence that plastics may also be [...]

Every year, over 400 million tons of plastic are produced and used around the world. This huge amount of plastic pollutes beaches, rivers, and even the deepest parts of the ocean—up to 11,000 meters down. But plastic doesn’t just hurt the environment. It also contributes to climate change, producing 1.8 billion tons of greenhouse gases each year. Scientists are also finding that plastic use can affect human health. Tiny plastic particles, known as microplastics, break off [...]

A study conducted by the Molecular Oncology Research Center (CPOM) at Hospital de Amor in Barretos (formerly Barretos Cancer Hospital) in the state of São Paulo, Brazil, has identified possible biomarkers that could guide the development of more personalized therapies for pediatric germ cell tumors (GCTs). Although GCTs account for only 3% of childhood cancers, they challenge doctors and researchers due to their diversity and the toxicity of available treatments. The main approach [...]

The production and use of over 400 million tons of plastic each year has polluted beaches, rivers, and even the deepest parts of the ocean, reaching depths of up to 11,000 meters. In addition to visible environmental impacts, plastic contributes to climate change. It is estimated that plastic production generates 1.8 billion tons of greenhouse gases per year. Scientific evidence also suggests that using plastic materials in everyday life has impacted human health. A large number of plastic [...]
