University of Pittsburgh Nov 17 2025 A team co-led by University of Pittsburgh’s Graham Hatfull has developed a method to construct bacteriophages with entirely synthetic genetic material, allowing researchers to add and subtract genes at will.  The findings open the field to new pathways for understanding how these bacteria-killing viruses work, and for potential therapies to fight the worsening problem of antibacterial resistance.    “This will speed up discovery,” Hatfull said.
