Scientists create human cells with squid-like transparency

The video discusses a research project inspired by female opalescent inshore squids, which can change their color to evade predators. This ability is due to leucophor cells in their skin containing reflectant proteins that scatter light, creating camouflage. Researchers have introduced these reflectant genes into human embryonic kidney cells, which then form ball-shaped nanostructures containing reflectant molecules, mimicking the optical behavior of squids.

What inspired the researchers' project on camouflage?

• The reflective nature of butterfly wings

• The ability of chameleons to change color

• The transparency of jellyfish

• The opalescent inshore squids' color-changing ability

What is the role of leucophor cells in squids?

• They provide energy to squids

• They help squids swim faster

• They allow squids to breathe underwater

• They contain reflectants that help in camouflage

What did researchers introduce into human embryonic kidney cells?

• Genes for color vision

• Genes for increased metabolism

• Genes expressing reflectant

• Genes for faster growth

What did the cultured cells develop?

• Spiral formations

• Flat structures

• Cubical shapes

• Ball-shaped nanostructures

How did the reflectant molecules behave in the cells?

• As if they were in bird feathers

• As if they were in squid skin

• As if they were in octopus skin

• As if they were in fish scales
