A fingerprint has been found in the tars used to build the oldest known wooden plank boat in Scandinavia, which provides a direct link to the seaborne raiders who used the boat over 2,000 years ago. By analysing the tar itself, Lund University researchers are closer to solving the long-standing mystery of where the attackers in the boat came from.

A new study reveals that the Halafian culture of northern Mesopotamia (c. 6200–5500 BCE) produced the earliest systematic plant imagery in prehistoric art, flowers, shrubs, branches, and trees painted on fine pottery, arranged with precise symmetry and numerical sequences, especially petal and flower counts of 4, 8, 16, 32, and 64. This suggests that early farming villages in the Near East already possessed sophisticated, practical mathematical thinking about dividing space and quantities, likely tied to everyday needs such as fairly sharing crops from collectively worked fields, long before writing or formal number systems existed.
