The discovery of bone tools dating back 1.5 million years in Tanzania indicates that early humans engaged in systematic tool-making much earlier than previously thought, pushing back the timeline for technological advancement. In a separate study, researchers found that human cells utilize their waste-disposal systems, particularly the proteasome, to produce antimicrobial peptides, revealing hidden antibacterial properties within proteins. This dual focus on ancient human technology and modern cellular defense systems highlights significant developments in our understanding of both early human culture and cell biology.
This discovery of 1.5-million-year-old bone tools in Tanzania raises intriguing questions about early human technology and the timeline of tool manufacture.
New research shows that human cells have a sophisticated waste-disposal system that can produce antimicrobial peptides to defend against infections, unlocking potential in proteins.
