Genetic tweaks allowed early humans to stand, balance and walk on two legs instead of moving on all fours like other primates, according to researchers.
The RAD52-DNA complex is a dynamic guardian of genomic stability. When this balance falters, cells may either self-destruct or, worse, turn cancerous.
Scientists have discovered a tardigrade protein, Dsup, that protects DNA from damage and may enhance human cellular resilience under extreme stress conditions.
