Bacterial Enzyme Keeps Rotifers’ Transposable Elements in Check
Christie Wilcox, PhD | Mar 3, 2022 | 5 min read
Jumping genes in bdelloid rotifers are tamped down by DNA methylation performed by an enzyme pilfered from bacteria roughly 60 million years ago, a study finds.
Genetic Parasites and a Whole Lot More

Photo: Ori Fragman, Hebrew University Hordeum spontaneum, the plant studied for BARE-1 retroelements. With genome sequences arriving almost as regularly as the morning paper, the public's attention is focused on genes--new genes to protect crops against pests; rogue genes that make bacteria resistant to antibiotics; faulty genes that, if fixed, could cure diseases such as muscular dystrophy. What many people don't realize is that genes account for only part of an organism's DNA, and in many c
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

Illuminating Behaviors
Douglas Steinberg | Jun 1, 2003 | 6 min read
Courtesy of Genevieve Anderson If not for Nobel laureates Thomas Hunt Morgan, Eric R. Kandel, and Sydney Brenner, the notion of a general behavioral model might seem odd. Behaviors, after all, are determined by an animal's evolutionary history and ecological niche. They are often idiosyncratic, shared in detail only by closely related species. But, thanks to Morgan's research in the early 20th century, and Kandel's and Brenner's work over the past 35 years, the fly Drosophila melanogaster, t

Understanding the dinoflagellates that regularly wreak havoc on marine and nearshore ecosystems in the Gulf of Mexico could help researchers mitigate the damage they cause.
Interdisciplinary Study Of Nonhuman Primates Gains Ground
Steve Bunk | May 10, 1998 | 8 min read
Date: May 11, 1998 Author: Steve Bunk Do apes have feelings? Do they recognize and understand emotions? Behavioral and biomedical scientists are beginning to put aside old differences concerning such questions and combine their efforts to shed new light on what nonhuman primates may reveal about human evolution. A national leader in this emerging interdisciplinary approach is the Yerkes Regional Primate Research Center at Emory University in Atlanta. In September of 1977, the university establ

Some Cancers Become Contagious

So far, six animal species are known to carry transmissible, “parasitic” forms of cancer, but researchers are still mystified as to how cancer can become infectious.
Syphilis: Then and Now

Researchers are zeroing in on the origin of syphilis and related diseases, which continue to plague the human population some 500 years after the first documented case.
