Reverse engineering in late Gothic vaulted ceilings

The ‘Gothic’ architectural style, which flourished during the high- and late-medieval periods, from the 12th to 16th centuries AD, gave Europe some of its greatest cathedrals, minsters and churches as well as an architectural treasure house of palaces, town halls and guild buildings among others. Importantly, the soaring open spaces conceived and constructed by the architects of the period were only made possible by the innovative ways of designing and constructing ambitious vaulted ceilings. How did those medieval builders go about designing these huge complex monuments? And in an era without computers and design software, how did they set down their visions and transmit them in usable form to the master builders and masons who created them?

Modern human culture could have emerged 44,000 years ago

In cooperation with the CNRS and University of Bergen When did human behaviour as we know it begin? Work conducted by an international team of researchers suggests that modern culture emerged 44,000 years ago. Their analysis of archaeological material discovered at Border Cave in South Africa has demonstrated that much of the material culture that characterized the lifestyle of San hunter-gatherers in southern Africa was part of the culture and technology of the inhabitants of Border Cave 44,000 years ago. This research, funded by an ERC Advanced Grant, is published in the online edition of the Proceedings of the National Academy of Sciences.
