A single brain is unfathomably complex. So brain researchers, whether they’re looking at datasets built from 300,000 neurons in 81 mice or from MRIs of 1,200 young adults, are now dealing with so much ...

Researchers with the global Human Cell Atlas (HCA) consortium report significant progress in their quest for a better understanding of the cells of the human body in health and disease, with the ...

Researchers have identified a variant in the gene TBX1 as key in the development of the unique morphology at the base of the skull. TBX1 is present at higher levels in humans than in closely related ...

Embryonic development, also known as embryogenesis, is a cornerstone in understanding the origins of life. But studying this marvel of intricate and layered biological processes in people faces ...

Scientists reveal unprecedented insights into human limb development, including the many intricate processes that govern their formation. Human fingers and toes do not grow outward; instead, they form ...

Thousands of previously “invisible” microproteins—tiny chains of fewer than 100 amino acids—can profoundly change human biology when mutated. A fundamental discovery is overturning decades of ...

Some newly reported clumps of cells growing in lab dishes have been hailed as the closest things to human embryos that scientists have ever made in the lab. These entities are human embryo models — ...

An Arizona bill that recently passed the state senate would mandate public schools to teach fetal development, a measure ...
