Neural tissue normally dies quickly without oxygen. Yet bird retinas—among the most energy-demanding tissues in the animal kingdom—function permanently without it. This may be relevant in future ...

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 ...

Scientists in Japan have created hybrid plant-animal cells, essentially making animal cells that can gain energy from sunlight like plants. The breakthrough could have major benefits for growing ...

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