Scientists have officially brought genetic engineering to the spider’s web. For the first time, researchers have created a gene-edited spider that spins red fluorescent silk.

Spider silk is known for being biodegradable, light, and durable. The Darwin‘s bark spider weaves the largest webs in the world, and its silk is the strongest biological material known to science.

That flashy female was in fact another male firefly, himself trapped in the web, and the spider may have manipulated his light beacon to lure you in. This high-stakes drama plays out nightly in ...

Male fireflies trapped in the spider’s web flash femalelike lights, ... Mysterious ‘little red dot’ galaxies have a possible origin story By Ken Croswell June 27, 2025.

Discover how CRISPR-Cas9 technology is revolutionizing spider silk production with red fluorescent fibers and advancing genetic research.

These big spiders can grow to 3in (7.6cm) in size and can be identified by their colorful blue and yellow markings on their bulbous bodies, with red markings on their undersides.
