Asthma, Genetics, and the Environment
Karen Young Kreeger | Apr 6, 2003 | 8 min read
Courtesy of Eric Erbe and Chris Pooley, ARS Image Gallery  SPRING CLEANING TARGETS: Tyrophagus putrescentiae, better known as dust mites, are microscopic, sightless, eight-legged arthropods that are natural inhabitants of indoor environments. Their droppings are the most common trigger of perennial allergy and asthma symptoms. Asthma is a classic example of gene-environment interaction. A host of environmental triggers, from cigarette smoke to cockroaches, can set it off. A dozen or so g

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.
Environment vs. Genes
Arielle Emmett | Aug 19, 2001 | 5 min read
Unlike the chicken-and-egg dilemma, scientists know that genes come before the environment. In genetically based diseases, however, the question is not when but how. How do environmental conditions and lifestyle choices interact with a person's molecular structure? "We're all groping in the dark to find out how to get a handle on this complexity," says Marianne Berwick, an epidemiologist at Memorial Sloan-Kettering Cancer Center, New York. Although scientists can now assess exposure levels to
Elemental Shortage

By Brendan Borrell ELEMENTAL SHORTAGE The world is running out of cheap phosphorus, the element that lies at the heart of great agricultural advances and thorny environmental problems. Biologists are only now beginning to understand what it means for evolution and human health. James Elser at a study site in southern Norway Although a limnologist in Phoenix and a molecular biologist in Atlanta have never met before, a single element ties them together.

The Orange and the Circus Tent Illustrations by Grady McFerrin What viruses teach us about the workings of mammalian cells. By Ari Helenius Article Extras 1 In those days, my interest was largely biochemical, particularly in the properties of membrane proteins, although I did also spend a lot of time trying to take the virus apart to its individual components, in an attempt to recreate the infectious particle from scratch. Needless to sa
The Inequality of Drug Metabolism
Karen Young Kreeger | Mar 17, 2002 | 6 min read
Editor's Note: This is the fifth article in a series on sex-based differences in the biology of males and females. The final article in the series will cover sex-based differences in life expectancy. Lisa Damiani More than 30 years ago, researchers noted for the first time the pharmacokinetic differences between men and women. They found that women pass antipyrine, a drug used to study liver metabolism, more quickly than men; this occurred around ovulation and during the luteal phase of their m
