Old ovaries, new eggs
Tia Ghose | Apr 11, 2009 | 2 min read
Are female mammals born with all the eggs they'll ever have, or can they produce new eggs into adulthood? The question has been vociferously debated, but now, a study published online in Nature Cell Biology today (April 12) reports that at least in mice, adult female ovaries have a store of stem cells that have the potential to generate new eggs. Human oocyte Image: Wikimedia CommonsThe study "is a huge step in quelling this debate," Jonathan Tilly, a reproductive biologist at Harvard Medical

The Surgisphere Scandal: What Went Wrong?
Catherine Offord | Oct 1, 2020 | 10+ min read
The high-profile retractions of two COVID-19 studies stunned the scientific community earlier this year and prompted calls for reviews of how science is conducted, published, and acted upon. The warning signs had been there all along.
Blood cells filmed in formation
Alla Katsnelson | Feb 10, 2009 | 3 min read
Researchers have helped resolve a long-standing debate about which precursors in the developing mammalian embryo give rise to blood cells, after tracking the birth of these cells using in-vivo imaging that lasts for days, according to linkurl:a report;http://www.nature.com/nature/journal/v457/n7231/full/nature07760.html in this week's Nature. The study is one of a handful of papers to come out in recent months to examine the question of hematopoietic cell origin. "I would say the nice thing abo
A Paradigm Shift in Stem Cell Research?
Ricki Lewis | Mar 5, 2000 | 9 min read
Photo: E.D. Laywell, UT MemphisMultipotent clones of cells derived from the adult human brain With the promises and challenges of stem cell research in the headlines, visions of artificial livers dance in the public's eye. Bioethicists, politicians, and citizens alike continue to debate whether public funds should be used to obtain cells from human embryos and fetuses. On the scientific front, however, the implications of stem cell research are even more profound than offering replacement parts.
In A Darwinian World, What Chance For Design?
Steve Bunk | Apr 12, 1998 | 7 min read
Swiss anthropologist Jeremy Narby counts himself among the relatively thin ranks of scientists willing to publicly announce their conviction that nature is "minded," that an intelligence lies behind the development of life. Such a position is heresy to the prevailing scientific view of naturalism, which holds that nature is self-sufficient and the result of undirected processes. These two differing viewpoints usually are framed in the context of a debate between theology and science--creationis
Bacteria Harbor Geometric “Organelles”
Amber Dance | Dec 1, 2018 | 10+ min read
Microbes, traditionally thought to lack organelles, get a metabolic boost from geometric compartments that act as cauldrons for chemical reactions. Bioengineers are eager to harness the compartments for their own purposes.
