Klipdrift Shelter, southern Cape, South Africa: preliminary report on the Howiesons Poort layers

  • by Christopher S. Henshilwood, Karen L. van Niekerk, Sarah Wurz, Anne Delagnes, Simon J. Armitage, Riaan F. Rifkin, Katja Douze, Petro Keene, Magnus M. Haaland, Jerome Reynard, Emmanuel Discamps and Samantha S. Mienies

Surveys for archaeological sites in the De Hoop Nature Reserve, southern Cape, South Africa resulted in the discovery of a cave complex comprising two locations, Klipdrift Cave and Klipdrift Shelter. Excavations commenced in 2010 with Later Stone Age deposits initially being recovered at the former site and Middle Stone Age deposits at the latter. The lithic component at Klipdrift Shelter is consistent with the Howiesons Poort, a technological complex recorded at a number of archaeological sites in southern Africa. The age for these deposits at Klipdrift Shelter, obtained by single grain optically stimulated luminescence, spans the period 65.5 ± 4.8 ka to 59.4 ± 4.6 ka. Controlled and accurate excavations of the discrete layers have resulted in the recovery of a hominin molar, marine shells, terrestrial fauna, floral remains, organic materials, hearths, lithics, ochre, and ostrich eggshell. More than 95 pieces of the latter, distributed across the layers, are engraved with diverse, abstract patterns. The preliminary results from Klipdrift Shelter presented in this report provide new insights into the Howiesons Poort in this sub-region and contribute further to ongoing knowledge about the complex behaviours of early Homo sapiens in southern Africa. Excavations at the Klipdrift Complex will continue in the future” (read more/open access).

crocodillium:

Kinematics turns any 3D shape into a foldable form for 3D printing.

Kinematics is a system for 4D printing that creates complex, foldable forms composed of articulated modules. Each component is rigid, but in aggregate they behave as a continuous fabric. Though made of many distinct pieces, these designs require no assembly. Instead the hinge mechanisms are 3D printed in-place and work straight out of the machine.

You can make and order (or print!) your own designs using the Kinematics app.

BionicKangaroo

Robotic recreation of the Kangaroo form put together by Festo to demonstrate energy-efficient movement (this was initially announced on April the 1st, but turns out to be real) - video embedded below:

With the BionicKangaroo, Festo has technologically reproduced the unique way a kangaroo moves. Like its natural model, it can recover the energy when jumping, store it and efficiently use it for the next jump.

On the artificial kangaroo, Festo intelligently combines pneumatic and electrical drive technology to produce a highly dynamic system. The stable jump kinematics plus the precise control technology ensure stability when jumping and landing. The consistent lightweight construction facilitates the unique jumping behaviour. The system is controlled by gestures.

Houghton Library, Harvard University

16th century surgeon Gaspare Tagliacozzi was particularly known for his skill in the method of reconstructing an amputated nose by grafting a flap of skin from the patient’s arm. The patient would have to spend three weeks with the arm immobilized in this position for the graft to take.

First prize in Science’s Visualization Challenge (video category) went to this NASA video by Greg Shirah, Horace Mitchell, and Tom Bridgman. It shows Earth’s “climate engine” — the wind patterns and ocean currents that are powered by the sun.
