The RNA World hypothesis posits RNA as early life's genetic material. A new model suggests asteroid impacts sterilized Earth until 4.4B years ago. Post-impact, hydrothermal vents fostered RNA's emergence around 4.33B years ago, predating LUCA by ~130M years, offering precise timeline insights.
A massive volcanic eruption in Chile buried a landscape, preserving clues about Andean mountain formation. New research suggests a slow, steady uplift of the crust over millions of years.
Researchers estimated T. rex's body temperature to be 97.3°F (36.3°C), comparable to humans and elephants, indicating it was a warm-blooded, active predator. This finding impacts understanding of its habitat and behavior during the Cretaceous period.
Scientists developed a new technique to read ancient papyrus scrolls carbonized by volcanic eruptions. By first scanning for leaded ink, they can then use X-rays and AI to decipher the text, potentially revealing lost wisdom from thinkers.
New research suggests a surprising pause in gray matter reduction during menopause, unlike changes seen in menarche and pregnancy. The study highlights the critical need for more research into how hormonal shifts impact the brain throughout a woman's life.
A pristine mastodon molar, identified as a Pacific mastodon, was unearthed in California. This significant fossil from the last glacial epoch provides valuable insights into prehistoric North America and species differentiation.
