Researchers successfully implanted a genetically modified pig liver into a human, proving that such an organ can function for an extended period. The graft supported essential liver processes before complications required its removal. Although the patient ultimately passed away, the experiment demonstrates both the potential and the complexity of xenotransplantation....

A new radiocarbon study has clarified the timing of the colossal Thera eruption, placing it before Egypt’s New Kingdom. Researchers analyzed artifacts tied to Pharaoh Ahmose, gaining rare access to museum materials. Their results favor a younger chronology for early 18th Dynasty Egypt. The revised timeline reshapes regional historical connections.

An immense Bronze Age settlement has emerged from the Kazakh Steppe, revealing a surprisingly urban and industrial society where archaeologists once expected nomadic camps. At Semiyarka, researchers uncovered massive residential compounds, a possible ceremonial or administrative building, and an entire industrial zone dedicated to producing tin bronze—an extremely rare discovery...

Researchers have uncovered a new species of wolf snake on Great Nicobar Island and named it Lycodon irwini in tribute to Steve Irwin. The glossy black, non-venomous snake grows up to a meter and appears confined to a small area. Scientists warn its limited habitat makes it vulnerable. The find...

Scientists have discovered that complex life began evolving much earlier than traditional models suggested. Using an expanded molecular clock approach, the team showed that crucial cellular features emerged in ancient anoxic oceans long before oxygen became a major part of Earth’s atmosphere. Their results indicate that early complexity developed slowly...
