Neural tissue normally dies quickly without oxygen. Yet bird retinas—among the most energy-demanding tissues in the animal ...

Plants and algae, meanwhile, use chloroplasts, which perform photosynthesis to generate energy from sunlight to power their cells. In a new study led by the University of Tokyo, the team inserted ...

The discovery fundamentally changes the understanding of a structure in the avian eye that has been misinterpreted for centuries.

Tissue optical clearing is a fundamental technique that enhances light penetration deep into biological samples by reducing light scattering through refractive index homogenization. This process ...

Researchers have long faced a blunt limitation in biology. They could delete proteins or switch genes off, but they could not finely tune how much of a protein existed in specific tissues over an ...

Scientists from Stanley Manne Children’s Research Institute at Ann & Robert H. Lurie Children’s Hospital of Chicago and Northwestern University report they have succeeded in regenerating fully ...

A new study led by researchers at the Johns Hopkins Kimmel Cancer Center, its Bloomberg~Kimmel Institute for Cancer ...
