lens

Researchers develop a new method to highlight specific cells that reside in the lens of a zebrafish.

A surgical technique that removes the lens but leaves endogenous stem cells to allow lens regrowth shows promise in animal and early human trials.

Photosynthetic cyanobacteria sense light in much the same way as a human eyeball, scientists show.

Cut off a newt’s tail or a leg, or remove a lens from its eye, and it grows back. However, whether newts can continue to do this throughout their lives, or lose the ability as they get older, has remained a mystery. 

Researchers find that newts are capable of regenerating body parts well into old age.

This lens-free, pinhead-size camera could someday grace the tip of a surgery needle or take cheap 3D images of cells.

A 16-year-long newt study finds that regeneration remains efficient with repetition and age.
