Neanderthals' Advanced Tool-Making Skills Unveiled through Ancient Glue Discovery

Scientists have discovered evidence that Neanderthals used a complex adhesive made of ocher and bitumen to create stone tools, indicating a higher level of cognition and cultural development than previously thought. The findings, reported in the journal Science Advances, suggest that Neanderthals had similar cognitive abilities to early modern humans in Africa. The discovery, made at the Le Moustier archaeological site in France, provides insight into the technological capabilities and cultural evolution of early humans.

Eco-friendly adhesives: Harnessing nature for sustainable bonding

Researchers are exploring the use of sustainably sourced components, such as lignin and epoxidized soybean oil, to develop high-strength adhesives. These bio-based materials offer advantages beyond renewability, including improved mechanical properties and reduced environmental impact compared to traditional epoxy resins. Inspired by natural adhesives found in mussels and other organisms, scientists are incorporating catechol-based compounds and weak bonds into biomimetic adhesives to enhance toughness and performance. The development of eco-friendly antifungal coatings and recyclable non-isocyanate polyurethanes further demonstrates the potential of sustainable materials in the adhesives industry.
