    High-altitude discovery sheds light on early settlers of Qinghai-Tibet Plateau

    A groundbreaking archaeological discovery has reshaped our understanding of early human settlement patterns at extreme altitudes. Chinese researchers have unearthed a Paleolithic site dating back approximately 12,000 years near Tsochen Tso Lake in Daocheng county, located within Sichuan Province’s Garze Tibetan Autonomous Prefecture. This remarkable find sits at an elevation exceeding 4,300 meters—the highest-altitude evidence of ancient human activity ever documented on the Qinghai-Tibet Plateau.

    The excavation, led by the Sichuan Provincial Cultural Heritage Administration, has yielded more than 190 meticulously crafted stone artifacts. These tools predominantly consist of small flake implements and microblades, demonstrating sophisticated knapping techniques and precision retouching that produced razor-sharp edges capable of processing animal hides and meat efficiently.

    According to Zheng Zhexuan, head of the excavation team and director of the Paleolithic Archaeology Institute at the Sichuan Provincial Institute of Cultural Relics and Archaeology, this discovery forms a crucial component of the extensive Piluo site complex. This broader archaeological landscape, dating back over 200,000 years with an average altitude of 3,750 meters, represents the earliest, most expansive, and culturally richest known settlement on the plateau.

    “This finding indicates that ancient human communities strategically capitalized on warmer climatic intervals to establish settlements alongside plateau lakes more than ten millennia ago,” Zheng explained. “The site demonstrates characteristics of a repeatedly occupied habitat rather than a temporary campsite, suggesting these early populations had developed sustainable adaptive capabilities for high-altitude environments.”

    Ongoing multidisciplinary research at the Piluo site complex includes detailed chronology studies and environmental archaeology analyses. Scientists are working to reconstruct precise scenarios of daily life for these ancient plateau dwellers, potentially revealing new insights into human resilience and environmental adaptation strategies during the Paleolithic era.

  • US official time gets 4.8 microseconds slower over storm-triggered power outage

    US official time gets 4.8 microseconds slower over storm-triggered power outage

    A severe windstorm that battered Colorado last week has unexpectedly impacted the United States’ most precise timekeeping infrastructure, causing the national time standard to fall behind by 4.8 microseconds. The incident occurred when powerful winds knocked out power to the National Institute of Standards and Technology’s (NIST) Boulder campus, disrupting the operation of atomic clocks that maintain official US time.

    The disruption began on December 17, 2025, when utility power failed at NIST’s Colorado facility during the intense windstorm. Although backup generators were available, a subsequent failure in one of these critical backup systems caused approximately 16 atomic clocks to lose connection with NIST’s measurement and distribution systems. These clocks, including hydrogen masers and cesium beam instruments, normally maintain the nation’s time standard through a weighted average of their readings.

    According to NIST supervisory physicist Jeffrey Sherman, the lapse resulted in NIST’s Coordinated Universal Time (UTC) becoming 4.8 microseconds slower than the correct standard. To contextualize this deviation, NIST spokesperson Rebecca Jacobson noted that a human blink typically takes approximately 350,000 microseconds (0.35 seconds).

    While the time discrepancy would be imperceptible to the general public, experts warn that such deviations could have more serious implications for critical infrastructure systems. The official US time standard serves as a reference for telecommunications networks, GPS signals, financial transactions, and other time-sensitive applications where precision is paramount.

    As of December 22, utility power had been restored to NIST’s Boulder facilities, and assessment and repair activities are currently underway. The incident highlights the vulnerability of even the most sophisticated scientific infrastructure to extreme weather events and the importance of robust backup systems for maintaining critical national standards.
