Should the scientific community abandon the 14-day rule for research on human embryos?
Ida Emilie Steinmark, PhD | Jul 5, 2023 | 2 min read
Research on human embryos is usually limited to the first 14 days of development, but as scientific capabilities improve, some argue that it is time to go further.
Stem Cell Discoveries Stir Debate
Douglas Steinberg | Nov 12, 2000 | 9 min read
Editor's Note: This is the first of two articles on questions raised by recent stem cell discoveries. The second article, focusing on various organs and the nervous system, will appear in the Nov. 27 issue of The Scientist. Researchers first isolated embryonic stem cells (ESCs) from mouse blastocysts almost 20 years ago, and a paper announcing the discovery of human ESCs emerged in 1998. Adult-derived stem cells (ASCs) have since become the rage in certain quarters of biology, with unexpected--

Do Epigenetic Changes Influence Evolution?
Katarina Zimmer | Nov 1, 2022 | 10+ min read
Evidence is mounting that epigenetic marks on DNA can influence future generations in a variety of ways. But how such phenomena might affect large-scale evolutionary processes is hotly debated.
On the left is a normally developing mouse embryo, on the right is a slightly larger mouse embryo that also contains horse cells that glow green.

Debate Over Stem Cell Origins Continues
Ricki Lewis | May 26, 2002 | 7 min read
In science, things are not always as they seem. So it is for transdifferentiation, the apparent interconvertibility of certain specialized cell types and an underlying theme at a symposium on stem cell biology and applications at the recent annual meeting of the American Association for Cancer Research (AACR) in San Francisco. "For the past three years, people have been saying that hematopoietic [blood-forming] stem cells can become just about any tissue, challenging the paradigm that there are

Does Human Epigenetic Inheritance Deserve a Closer Look?
Catherine Offord | Apr 4, 2022 | 10+ min read
The concept of epigenetic inheritance has long been controversial. Some researchers hope that new data on cross-generational effects of environmental exposures will help settle the debate.

Setting the Record Straight
Daniel Cossins | Oct 1, 2014 | 10+ min read
Scientists are taking to social media to challenge weak research, share replication attempts in real time, and counteract hype. Will this online discourse enrich the scientific process?
Scientific Enterprise At Critical Juncture, Say Panelists, Researchers
Steven Benowitz | Oct 13, 1996 | 10+ min read
MISCONDUCT POLICY: University of Illinois' C.K. Gunsalus cites problems of oversight in academia. Is science in crisis? Scientists, historians, administrators, and others have debated this issue over the last few decades. The controversial topic was the impetus for a September 19 conference at George Washington University (GWU). Panelists at the day-long symposium, titled "Science in Crisis at the Millennium," think something has gone awry. Keith Yamamoto, University of California, San Franc
