Catholic Bishops in the United States and Australia continue to speak out in clarification of what constitutes ethical stem cell research as they respond to a new study which, they say, contains ...

Scientists are exploring ways to mimic the origins of human life without two fundamental components: sperm and egg. They are coaxing clusters of stem cells – programmable cells that can transform into ...

For several years, researchers studied human embryonic stem cells (ESCs) to understand the unique features of these pluripotent cells, but on their own, they poorly resembled the complex structures ...

Descriptions of the embryo go back at least to the time of Aristotle, but it has only been since the late 19 th century and early 20 th century that advances in experimental approaches allowed ...

From the moment an embryo starts to take shape, two-way communication is critical for making sure tissues and organs develop correctly. Two of the first physical structures to form in the embryo are ...

Megan Molteni reports on discoveries from the frontiers of genomic medicine, neuroscience, and reproductive tech. She joined STAT in 2021 after covering health and science at WIRED. You can reach ...

Caltech researchers have developed a powerful new method for creating embryo-like structures from stem cells that could transform how we study fertility. Subscribe to our newsletter for the latest sci ...

In a previous column, I promised that I would do some additional pieces on the Endangered Species Act and private property rights. Those pieces are still in the hopper and will run at a later date.

(CNN) -- A human embryo, containing about a couple hundred cells, is smaller than the period at the end of a sentence. Scientists need strong microscopes to see these precursors to life, and to take ...

Jennifer Zenker receives funding from NHMRC and Viertel Foundation. Most people have heard of stem cells. They are often described as “miracle” cells –ones that can grow into any other type of cell in ...

As the Bush administration approaches a decision on stem cell research, the caricatures have already been drawn. On one side are the human benefactors who wish only a chance to use the remarkable ...
