Why Pancreatic Cancer Is So Deadly: New Study Reveals Hidden Invasion Pathway
Publicado em 24 de janeiro de 2026
Brazilian researchers have found that stellate pancreatic cells produce periostin, which reshapes surrounding tissue and allows tumors to spread more easily, helping explain why the disease is so aggressive and deadly.
A new Brazilian study published in the scientific journal Molecular and Cellular Endocrinology has identified a critical role for the protein periostin and stellate pancreatic cells in enabling pancreatic cancer to invade nerves and spread at an early stage, raising the [...]

Deadly Frog Fungus Devastating Amphibians Worldwide Traced Back to Brazil
Publicado em 19 janeiro 2026The fungus Batrachochytrium dendrobatidis has played a major role in the worldwide decline of frogs and toads. Its origins were investigated in a study conducted by scientists from the State University of Campinas, which examined where this damaging strain first emerged. The chytrid fungus (Batrachochytrium dendrobatidis), commonly known as Bd, is widely recognized as a major factor behind the global decline of amphibians. Scientists have discovered that the pathogen exists in multiple [...]ver notícia -
These Giant Long-Necked Dinosaurs Could Stand Upright – and Scientists Finally Figured Out Why
Publicado em 15 janeiro 2026By applying computational engineering methods to model weight and gravitational forces acting on sauropod femurs, researchers found that these massive four-legged dinosaurs were generally able to stay upright while feeding, mating, and defending themselves. Sixty-six million years ago, two types of long-necked, four-legged dinosaurs had an edge over other sauropods because they could readily rise up and remain standing on their hind legs for long stretches of time. This ability likely helped [...]ver notícia -
Artificial Saliva Made From Sugarcane Shows Promise Against Severe Cavities
Publicado em 14 janeiro 2026Researchers at the University of São Paulo found that these effects become stronger when the molecule is used together with fluoride and xylitol, rather than on its own. An experimental artificial saliva developed as a mouthwash may help protect teeth in people with head and neck cancer. The product is made using the CANECPI-5 protein, which is extracted from sugarcane and altered under laboratory conditions. For many cancer patients, radiation therapy delivered near the mouth damages [...]ver notícia -
Brazil May Hold the Missing Keys to Extreme Human Longevity
Publicado em 12 janeiro 2026A Viewpoint published on January 6 in Genomic Psychiatry by Dr. Mayana Zatz and colleagues at the Human Genome and Stem Cell Research Center at the University of São Paulo argues that Brazil may be one of the most valuable yet overlooked places to study extreme human longevity. The article draws on the team's ongoing nationwide research involving exceptionally long-lived individuals while also summarizing recent scientific advances in the biology of supercentenarians. Why Living Past [...]ver notícia -
Scientists Find a Spider Wearing a “Pearl Necklace” – and It’s Made of Living Parasites
Publicado em 08 janeiro 2026A chance observation of an unusual spider led scientists to identify a new parasitic mite species in Brazil. While sorting through spiders and scorpions in the Zoological Collections Laboratory at the Butantan Institute in São Paulo, Brazil, researchers noticed something unusual. A spider only a few millimeters long appeared to be wearing a strand that looked like a pearl necklace, so they asked a colleague who specializes in mites to take a look. Ricardo Bassini-Silva, a researcher and [...]ver notícia -
According to Scientists, This Brazilian Plant Could Help Treat Arthritis
Publicado em 14 dezembro 2025Alternanthera littoralis, commonly called Joseph’s Coat, is native to Brazil’s coastal regions and has a long history of use in treating microbial infections and parasitic diseases. Scientists in Brazil from the Federal University of Grande Dourados (UFGD), the State University of Campinas (UNICAMP), and São Paulo State University (UNESP) have carried out new research on the Joseph’s Coat plant (Alternanthera littoralis), demonstrating its safety along with anti-inflammatory, [...]ver notícia -
Harvard Study Unlocks New Potential Treatments for Diabetes and Obesity
Publicado em 06 dezembro 2025A study reveals that the liver acts as a bidirectional hub, exchanging gut-microbiome-derived metabolic products with the heart. A research team supported by FAPESP and working at Harvard University in the United States has identified a collection of metabolites that move from the intestine to the liver and then reach the heart, which distributes them throughout the body. These compounds influence key metabolic processes in the liver and affect how the body responds to insulin . According [...]ver notícia -
Scientists Warn: “Almost Half of the Beaches Will Disappear by the End of the Century”
Publicado em 19 novembro 2025Coastal ecosystems are being crushed by rising sea levels linked to urbanization. Beaches across the globe are experiencing a form of “crushing,” a process driven by rising sea levels linked to climate change, along with the growing development of coastal regions. These pressures disrupt the wide variety of species that live in sandy environments, reduce opportunities for tourism and fishing, and increase the risk faced by coastal cities as the ocean moves inland. This concern [...]ver notícia -
Ultra-Processed Foods Are Fueling a Global Health Crisis, Experts Warn
Publicado em 18 novembro 2025A major new three-paper Series in The Lancet shows that ultra-processed foods are pushing aside fresh, minimally processed meals worldwide. The evidence links rising UPF consumption to poorer diet quality and higher risks of chronic conditions such as obesity, diabetes, heart disease, and other long-term illnesses. The authors stress that while more research will deepen our understanding, the science already shows enough harm to justify immediate public health action. They argue that waiting [...]ver notícia
