The study examined the remains of *Aratasaurus museunacionali*, a 115-million-year-old dinosaur discovered inside a Brazilian mine in 2008. By analyzing tiny oval-shaped structures, scientists detected hemoglobin-related heme B along with traces of collagen, iron, carbon, and nitrogen. The unexpected preservation was facilitated by rapid burial in microbial mats and the formation of hausmannite mineral casings around the cell-like features.

Time has a way of taking almost everything away. Bodies decay. Tissues disappear, and even bones gradually change as millions of years pass. Out of the excruciating cycle of time, nature sometimes decides to find a loophole by preserving a few traces for us to find and know that we were not the only ones and we won't be. One day, we find something that makes us wonder how that's even possible, and the next, nature throws even bigger mind-boggling stuff at us. Something similar happened with a group of palaeontologists when they found dinosaur blood.
When we think of dinosaur fossils, we usually imagine enormous skeletons, sharp teeth and footprints preserved in rocks for millions of years. But what if I told you that some fossils may hold traces of something far more delicate? In a study led by researchers at Curtin University, scientists examined a 115-million-year-old dinosaur fossil and reported evidence of structures resembling red blood cells, along with collagen-related molecules. The findings offer a rare glimpse into the biological material that may survive inside fossils long after…
Researchers analyzing the Las Minillas site in southern Spain have identified it as Iberia's largest securely dated Late Bronze Age copper mine. Chemical tracing revealed that metals produced here thousands of years ago reached northern Europe through complex exchange routes. These findings provide compelling evidence of expansive prehistoric networks linking Mediterranean raw material producers with distant communities across the continent.
Researchers observing longevity factors have identified a link between surgical sterilization and increased survival times in laboratory rodents. The initial finding indicates that altering reproductive biology directly influences longevity outcomes in these animal subjects. However, the exact physiological mechanisms and supporting data remain unreleased pending further disclosures from the study.
Atmospheric scientists are closely tracking unprecedented stratospheric changes high above the Arctic that could fundamentally disrupt typical seasonal circulation. While these high-altitude wind shifts historically push severe cold and wintry conditions into Europe, the unusual timing leaves ground-level effects highly unpredictable. Forecasters emphasize that because Arctic temperatures have not yet bottomed out, any direct winter weather impacts on Britain remain unconfirmed.
