Could Dad’s Mitochondrial DNA Benefit Hybrids?
Alejandra Manjarrez, PhD | Jan 20, 2022 | 7 min read
Studies have found that organisms can inherit mitochondria from male parents in rare instances, and both theoretical and experimental work hint that this biparental inheritance is more than just a fluke.
Gender-Based Biology Courses Take Diverse Forms
Ricki Lewis | Nov 8, 1998 | 9 min read
Introductory general biology courses and textbooks cover a vast amount of material. They tend to stress the similarities of life at the molecular and cellular levels, with Homo sapiens considered but one of many species. For students wishing to learn specifically about the female body, or about differences between the sexes, these courses aren't usually appropriate. ANALOGY: Like women's absence in past medical tests and clinical trials, many problems have not been addressed in biology, anat

Surpassing the Law of Averages
Jeffrey M. Perkel | Sep 1, 2009 | 7 min read
By Jeffrey M. Perkel Surpassing the Law of Averages How to expose the behaviors of genes, RNA, proteins, and metabolites in single cells. By necessity or convenience, almost everything we know about biochemistry and molecular biology derives from bulk behavior: From gene regulation to Michaelis-Menten kinetics, we understand biology in terms of what the “average” cell in a population does. But, as Jonathan Weissman of the University of Califo
Of Cells and Limits

Leonard Hayflick has been unafraid to speak his mind, whether it is to upend a well-entrenched dogma or to challenge the federal government. At 86, he’s nowhere near retirement.
Recent Trials for Fragile X Syndrome Offer Hope

Despite a solid understanding of the biological basis of fragile X syndrome, researchers have struggled to develop effective treatments.
Exotic Species, Locales All In Day's Work For Conservation Biologists
Karen Young Kreeger | Jan 22, 1995 | 9 min read
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
