Israeli researchers study ancient flint to measure Earth's magnetic field
Researchers from Tel Aviv University, the University of California San Diego and Rome's Instituto Nazionale di Geofiscia e Vulcanologia have studied ancient pottery found in Jordan to understand the magnetic field that once prevailed in the Middle East between 10,000 and 8,000 years ago.
Led by TAU's Prof. Erez Ben-Yosef and UCSD's Prof. Lisa Tauxe, the research team studied pottery and burnt flints on which the magnetic field was recorded.
This is important, because as has been noted by prior studies, Earth's magnetic field, which protects the planet from radiation, has been weakening.
