Updated : 2 years, 7 months ago IST
In the "black box" of human development known as gastrulation, an embryo transforms from a hollow, spherical structure to a multilayered one. Human embryos are typically not cultured for longer than 14 days due to bioethical concerns, and gastrulation happens between 17 and 21 days after fer

Researchers create human embryo-like entities with extraembryonic tissue
Updated : 5 months, 1 week ago IST
Gastrulation is a "black box" of human development in which an embryo reorganises itself from a hollow spherical to a multilayered structure. Because of bioethical considerations, human embryos are normally not cultured for more than 14 days, and gastrulation occurs between 17 and 21 days po

Walling off or 'bunkering' retina can save eyesight, suggests study
Updated : 4 years ago IST
Connecticut [US], March 8 (ANI): The retina is a layer of photoreceptors cells and glial cells within the eye that captures incoming photons and transmits them along neuronal pathways as both electrical and chemical signals for the brain to perceive a visual picture. Chronically stressing th
