Studying the process of brain formation illuminates just how much of development is a series of tiny miracles. Only a few weeks after a human egg is fertilized, a sheet of cells called the neural ...

A new study shows, for the first time, how the human genome folds and moves in 3D over time to control when genes turn on and ...

In two new studies, scientists at Oregon Health & Science University have uncovered detailed blueprints of how certain molecular "gates" in human cells work—findings that could open doors to new ...

Zebrafish can regenerate sensory hair cells that humans permanently lose, like those in the inner ear linked to hearing and balance. New research reveals two specific genes that control how different ...

Megan Baldridge and her co-workers will use their Global Grant for Gut Health (GGGH) to examine which human proteins interact with bacteriophage viruses in the gut, and how this might trigger ...

Creating human eggs from adult cells just got one step closer to reality. A technique used in cloning combined with fertilization and a bit of chemical coaxing caused human skin cells to produce eggs ...

Every second, millions of blood cells are produced in the human body, and about 90% of the cells replaced daily are blood cells. These include red blood cells essential for oxygen transport, platelets ...

A human cell is a Rube Goldberg machine like no other, full of biological chain reactions that make the difference between life and death. Understanding these delicate relationships and how they go ...

Stem cells age faster and become functionally exhausted in low Earth orbit, making crewed long-duration space travel even more challenging. When you purchase through links on our site, we may earn an ...

Scientists have pinpointed and described unusual subtypes of fat cells that may help scientists explain why gut fat is linked to poor health. The research could open up new avenues for medical ...

Scientists have developed an experimental way to study how human embryos implant in a uterus, which may provide new insights into why miscarriages occur and how they can be prevented.

Seals give birth only when conditions are right. After mating, a female seal can delay implantation of the embryo in the ...
