Neanderthals Used Pine Resin as Glue to Haft Stone Tools into Handles

The occasional use of stone tools as ‘strike-a-lights’ was a technocultural feature shared among Neanderthals in France.
Jun 27, 2019 by News Staff

The hafting of stone tools was an important advance in the technological evolution of Paleolithic humans. Joining a handle to a knife or scraper and attaching a sharp point to a wooden shaft made stone tools more efficient and easier to use. According to new research, published in the journal PLoS ONE, Neanderthals living in Europe from about 55,000 to 40,000 years ago traveled away from their caves to collect resin from pine trees, and then used...

This enhanced-color view of Enceladus is largely of the southern hemisphere and includes the south polar terrain at the bottom of the image. Ancient craters remain somewhat pristine in some locales, but have clearly relaxed in others. Northward-trending fractures, likely caused by a change in the moon’s rate of rotation and the consequent flattening of the moon’s shape, rip across the southern hemisphere. The south polar terrain is marked by a striking set of ‘blue’ fractures and encircled by a conspicuous and continuous chain of folds and ridges, testament to the forces within Enceladus that have yet to be silenced. The mosaic was created from 21 false-color frames taken during Cassini’s close approaches to Enceladus on March 9 and July 14, 2005. Images taken using filters sensitive to UV, visible and IR light (spanning wavelengths from 338 to 930 nm) were combined to create the individual frames.

Composite image of Uranus’ atmosphere and rings at radio wavelengths, taken with the ALMA in December 2017. Dark bands in Uranus’ atmosphere at these wavelengths show the presence of radiowave-absorbing molecules, in particular hydrogen sulfide gas, whereas bright regions like the north polar spot contain very few of these molecules.
