doorjambs, and lintels—the standout discovery was a pylon featuring an Egyptian-style door dating back to the Hellenistic period. Researchers suggest this artifact was part of the lighthouse’s primary entrance, a monumental gateway that had previously...

earth transitioning from desert sand to lake sediment, dating to roughly 55,000 years ago. This timeframe coincides with a period when the Arabian climate was becoming significantly wetter. Stone tool from Jebel Katefeh-1 (JKF-1), shown from multiple...

etched into marine rock layers across the globe. Known as paleodictyon, these patterns first emerged during the Cambrian period over 500 million years ago. Despite their ancient origins, the mystery persists because these structures are still being...

on the design of the ceramic vessels, the team—led by scholars including Dr. Xenophontas Dimas—has dated the wreck to a period between the 1st century BCE and the 1st century CE. 6,000 Roman amphorae found inside the fiskardo shipwreck. Credit: Ionian...

Kidnappers eruption. The findings, recently published in Alcheringa: An Australasian Journal of Palaeontology, illustrate a period of intense ecological transformation. The collaborative project included experts from Flinders University, the Canterbury...

could observe how the nucleus behaves in environments akin to deep space. The study, which tracked cells over a 24-hour period, yielded several surprising findings: While strong fluid flows caused cells to elongate, simulated microgravity left the cell...

Caesarea during this era. The wealth of items, including fragments of domestic pottery used for water storage, points to a period of significant economic stability. As Dr. Sharvit and Dr. Planer concluded, the sheer volume and diversity of these finds...

of Saturn is currently undergoing a slow, cyclical transformation. Following a rare “ring plane crossing” in March 2025—a period when Earth aligned with the razor-thin profile of the rings, making them nearly invisible—the ring system has begun to tilt...

secondary burial rites or simple disturbance. The recent discovery of two intact burials from the Pre-Pottery Neolithic B period (roughly 8,700 to 8,000 BCE) has provided a missing link. One interment, discovered in a zone designated as trench DR1,...

early Homo developed human-like limb adaptations. Credit: Science Advances This evolutionary turning point coincides with a period of rapid brain expansion. While scholars have long debated the drivers of this encephalization, including potential...

approximately 150 million years, providing a unique window into the reproductive lives of creatures from the Late Jurassic period. Discovered along the cliffs of Santa Cruz beach, about 50 kilometers north of Lisbon, the find consists of a cluster of...

at least 17,100 years ago, suggests that prehistoric populations were established in the immediate vicinity during the period in question. “If humans lived in Wales during the Ice Age, why not walk across when it was close?” von Petzinger remarked. Lost...

Way. By mapping how radiation travels through these environments, researchers hope to gain insights into the “reionization” period of the early universe, a transformative era when light began to permeate the previously neutral cosmos. The success of...

Because fluorite typically precipitates from hot water circulating through volcanic rock, its presence indicates a period of hydrothermal activity occurring well after the initial groundwater and lake-driven events. This discovery underscores the...

lower elevations, the rover encountered rocks where olivine grains had been fractured and altered. This suggests an initial period where carbon dioxide-rich groundwater seeped through the bedrock, precipitating carbonate deposits that now stand out as...

holes rotating into view. These features are expected to channel high-speed solar wind toward Earth, with another potential period of heightened geomagnetic activity anticipated around October 11. For now, the global scientific community continues to...
