Scientists image molecules vital for gene regulation

All the trillions of cells in our body share the same genetic information and are derived from a single, fertilized egg. When this initial cell multiplies during fetal development, its daughter cells become more and more ...

Complex life a billion years earlier than thought?

Researchers said Tuesday they had uncovered fossils showing that complex life on Earth began more than 1.5 billion years ago, nearly a billion years earlier than previously thought.

Functional nerve cells from skin cells

A new method of generating mature nerve cells from skin cells could greatly enhance understanding of neurodegenerative diseases, and could accelerate the development of new drugs and stem cell-based regenerative medicine.

New insights into how stem cells determine what tissue to become

Within 24 hours of culturing adult human stem cells on a new type of matrix, University of Michigan researchers were able to make predictions about how the cells would differentiate, or what type of tissue they would become. ...

Scientists turn stem cells into precursors for sperm, eggs

Human embryonic stem cells derived from excess IVF embryos may help scientists unlock the mysteries of infertility for other couples struggling to conceive, according to new research from the Stanford University School of ...
