The science world is freaking out over this 25-year-old’s answer to antibiotic resistance | Science Alert

But Shu Lam, a 25-year-old PhD student at the University of Melbourne in Australia, has developed a star-shaped polymer that can kill six different superbug strains without antibiotics, simply by ripping apart their cell walls.

“We’ve discovered that [the polymers] actually target the bacteria and kill it in multiple ways,” Lam told Nicola Smith from The Telegraph. “One method is by physically disrupting or breaking apart the cell wall of the bacteria. This creates a lot of stress on the bacteria and causes it to start killing itself.”

Questions:

  • Why is this an important discovery?
  • What might be a negative impact of this?

Mobbs is certain the use of 3D-printing in medicine will increase exponentially. “There’s no doubt this is the next big wave of medicine,” he said. “For me, the holy grail of medicine is the manufacturing of bones, joints and organs on-demand to restore function and save lives.”
