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 ...

Every winter, as the air sharpens and scarves return to shoulders, an old visitor also makes a reappearance: the flu. It ...

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 ...

Scientists have finally watched influenza viruses break into living human cells in real time, catching the microscopic ...

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 ...

This breakthrough represents a big step toward creating animal hybrids capable of growing human-compatible organs, easing the ...

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 ...

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 ...

When cells proliferate, genomic DNA is precisely duplicated once per cell cycle. Abnormalities in this DNA replication process can cause alterations in genomic DNA, promoting cellular ageing, cancer, ...

Your skin is in a constant state of reinvention. Every month, your body sheds and regenerates its entire outer layer—a ...

The human small intestine absorbs nutrients while protecting us from potentially harmful microbes. One of the cell types that ...

Scientists have uncovered a surprising genetic workaround that helps cells cope with Friedreich’s ataxia, a rare and devastating disorder.
