A recent study from Brazil, featured in the journal Molecular and Cellular Endocrinology, presents new insights into how pancreatic cancer develops the capacity for early spread. Researchers have identified a protein known as periostin, along with stellate cells in the pancreas, as key players in facilitating the invasion of cancer cells into surrounding nerves. This nerve invasion is a significant precursor to metastasis and is closely associated with the aggressiveness of the cancer. The [...]

Researchers at the Zoological Collections Laboratory of the Butantan Institute in São Paulo, Brazil, recently made an intriguing discovery while studying spiders and scorpions. They observed what appeared to be a delicate pearl necklace on a tiny spider, measuring just a few millimeters in length. Confused by this peculiar sight, the team sought insights from Ricardo Bassini-Silva, a specialist in mites and curator of the laboratory's Acarological Collection. Bassini-Silva quickly [...]

Chile's Vera Rubin Observatory, boasting the world's largest digital camera, has discovered a mountain-sized asteroid, 2025 MN45, spinning at an astonishing rate of every 1.88 minutes. This 'ultra-fast spinner' challenges existing theories about asteroid composition, suggesting a surprising material strength. The observatory's powerful sky-scanning capabilities are ushering in a new era of asteroid discovery. Asteroids are one of the most interesting space objects found [...]

The Vera C. Rubin Observatory has discovered the fastest-spinning large asteroid ever recorded using the world’s largest digital camera. The unusually strong space rock, found during early survey observations, challenges existing ideas about asteroid structure. Scientists say the find highlights Rubin’s potential to reveal hidden populations of asteroids and offer fresh insights into how the Solar System formed and evolved over billions of years. A new telescope has revealed an unusually [...]

In a breakthrough that feels like something out of science fiction, physicists have discovered a brand-new "quantum state" of matter. This isn't just a minor tweak to what we already know; it's a bridge between two major worlds of physics that were previously thought to be completely separate. What actually happened? Think of it like this: In physics, there are two big "trends" right now. Quantum Criticality: This is when electrons are in a frantic state of indecision, [...]

Scientists studying Brazil's oldest people believe they may be closer to understanding why some humans live far longer than average. While most people live around 70 years, a small number reach 100, and an even rarer group lives beyond 110. These individuals, known as supercentenarians, have long fascinated researchers searching for the secrets of longevity. A new viewpoint published in Genomic Psychiatry highlights findings from an ongoing Brazilian study that focuses on centenarians [...]

Scientists call them supercentenarians, people who are aged 110 or older. It’s estimated only a handful of such individuals remain in the world, who were born in another century, before the discovery of Penicillin or the invention of television. They even predate zippers. In an article published this month in Genomic Psychiatry, Dr Mayana Zatz and colleagues from the Human Genome and Stem Cell Research Center, University of São Paulo, wrote Brazil’s incredible genetic diversity must be [...]

The chytrid fungus, also known as Batrachochytrium dendrobatidis (Bd), has emerged as a significant driver of amphibian declines globally, affecting over 500 species of frogs and toads. Strains of this deadly fungus have been identified in various regions worldwide, with an alarming rate of population crashes being linked to these genetic variants. Researchers have traced the international spread of Bd primarily to the commercial trade of bullfrogs (Aquarana catesbeiana), a North American [...]

Artificial saliva? Yes, you read it right. A new fascinating discovery in the field of dental science is drawing a lot of attention. An artificial saliva was made using sugarcane protein that may help protect the teeth in people who suffer from dry mouth, which is more common in cancer patients. Researchers in Brazil developed this, and this innovation does not just help with mouth dryness; it also protects the teeth by mimicking the natural defense system of saliva. This gives hope to [...]
