Ancient DNA Traces Plague's 400-Year Persistence Across Europe After Black Death

Researchers have used ancient DNA to reconstruct how plague repeatedly returned to Europe for more than 400 years after the Black Death, providing new insights into how the disease evolved and spread across the continent. The study analyzed genetic material recovered from archaeological remains, tracing the pathogen's trajectory

Fossil Teeth Reveal T. Rex Body Temperature Was Nearly Human-Like

A new study analyzing chemical clues preserved in fossilized Tyrannosaurus rex teeth has determined that the dinosaur maintained a body temperature of approximately 97 degrees Fahrenheit—nearly identical to that of modern humans. The research team examined isotopic signatures embedded within the enamel of T. rex teeth dating back roughly

Researchers Identify 'Smoldering' Cell Defect That May Explain Why IBD Returns

A research team has uncovered a molecular mechanism that may help explain why inflammatory bowel disease (IBD) so often returns after patients enter remission. The findings suggest that even when people feel well, their intestinal cells can remain in a primed state that leaves them vulnerable to future flare-ups. The

Heat-Loving Microbe Enzyme Offers Clues to Ancient Nitrogen Fixation

Researchers have identified a deep-sea microbe possessing an enzyme capable of converting atmospheric nitrogen into ammonia at temperatures that would denature most proteins. The enzyme's exceptional heat resistance and newly characterized reaction state are providing insights into what may be an ancient, shared biological mechanism for nitrogen fixation.

Rare Brain Cells Identified as Potential Sleep Triggers

Sleep has long been one of neuroscience's enduring mysteries—despite spending roughly a third of our lives in this state, the exact cellular triggers have remained elusive. New research is now shedding light on the specific neurons that may be responsible for putting our brains to sleep. Scientists

"Zombie Cells" Discovery Reveals How Damaged Tissue Rebuilds Itself

Scientists have uncovered a striking cellular phenomenon: a subset of cells that can trigger the machinery of programmed cell death, escape that process intact, and then actively contribute to rebuilding damaged tissue. According to research published in Science Daily, these surviving cells and their descendants demonstrate a remarkable trait—their
