Infographic: The Genetics of Fragile X Syndrome
Randi Hagerman | Sep 1, 2019 | 3 min read
Variation in the number of CGG repeats in the FMR1 gene at the bottom of the X chromosome can lead to increased levels of mRNA or decreased levels of protein—both conditions that cause disease.

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
Cloning Capsized?
Ted Agres | Aug 19, 2001 | 10+ min read
Biopharmaceutical researchers fear how pending federal legislation outlawing the cloning of human cells will restrict their abilities to find cures for major degenerative diseases.1,2 Some also see lawmakers impinging on established nonhuman cloning techniques essential for the discovery of new drugs and therapies. The source of all this worry? The US House of Representatives passed July 31 by a wide margin a bill (H.R. 2505) sponsored by Reps. David Weldon (R-Fla.) and Bart Stupak (D-Mich.) th
Epigenetics: Genome, Meet Your Environment

©Mehau Kulyk/Photo Researchers, IncToward the end of World War II, a German-imposed food embargo in western Holland – a densely populated area already suffering from scarce food supplies, ruined agricultural lands, and the onset of an unusually harsh winter – led to the death by starvation of some 30,000 people. Detailed birth records collected during that so-called Dutch Hunger Winter have provided scientists with useful data for analyzing the long-term health effects of prenat
Exotic Species, Locales All In Day's Work For Conservation Biologists

Traveling to the ends of the earth in pursuit of biological quarry is not part of the job description for the average molecular biologist. But for anthropologist Don Melnick, going to work means trekking through the jungles of Southeast Asia for blood samples from the Javan silvery gibbon and other endangered animals. And the jobs of geneticist John Avise and biologist Brian Bowen entail long nights on tropical beaches waiting for nesting sea turtles. The following are the top ecology journal
