What happened

Producing spider silk is a biological feat Gaby Clark Scientific Editor Alexander Pol Deputy Editor "Spider-Man: Brand New Day" turns organic web production into a superpower.

Why it matters

In the 2026 film, Tom Holland's character, Peter Parker, begins producing webbing inside his body and shooting it from his wrists, rather than firing synthetic web fluid from the wrist-mounted mechanical web-shooters he used in earlier films.

Common ground

The switch transforms a familiar superhero technology into a biological ability and highlights the spectacular properties of real spider silk.
