Engineering the Microbiome: CRISPR Leads the Way
Mariella Bodemeier Loayza Careaga, PhD | Mar 15, 2024 | 10+ min read
Scientists have genetically modified isolated microbes for decades. Now, using CRISPR, they intend to target entire microbiomes.
Weathering Hantavirus: Ecological Monitoring Provides Predictive Model
Steve Bunk | Jul 4, 1999 | 7 min read
Photo: Steve Bunk Dave Tinnin, field research associate in the University of New Mexico's biology department, takes blood samples and measurements of rodents caught on the research station grounds. At the end of a freeway exit near Soccoro, N.M., the hairpin turn onto a gravel road is marked by a sign that warns, "Wrong Way." But it isn't the wrong way if you want to reach the University of New Mexico's (UNM) long-term ecological research (LTER) station. The sign's subterfuge is the first indi

Renewing the Fight Against Bacteria
Jennifer Fisher Wilson | Mar 3, 2002 | 6 min read
In the 1940s, the mass production of penicillin led to a sensational reduction in illness and death from bacterial disease. A resulting golden era of bacterial research emerged with new classes of antibiotics, and by 1969, US Surgeon General William H. Stewart told Congress: "The time has come to close the book on infectious disease." As a result, fewer new students specialized in bacterial physiology, and federal funders shifted their focus to more immediately pressing diseases, as did many pha
African Sleeping Sickness: A Recurring Epidemic
Ricki Lewis | May 12, 2002 | 5 min read
African trypanosomiasis is making an unwelcome comeback. But unlike other returning diseases, this one has a drug treatment—eflornithine—that disappeared from the market when it failed to cure cancer. Yet like Viagra's origin from a curious side effect in a clinical trial, so too was eflornithine reborn. "When it was discovered that it removes mustaches in women, it suddenly had a market: western women with mustaches," says Morten Rostrup, president of the international council for M
How to Create a Successful Fish Tale?
A. J. S. Rayl | Aug 19, 2001 | 10+ min read
More than 80 percent of the planet's living organisms exist only in aquatic ecosystems. Some may harbor secrets to human origins, and clues, treatments--perhaps even cures--for human disease. Some are critical bioindicators that portend the health of the biosphere. Yet, overall, scientists know little about the biochemical processes of these life forms. The vast, rich knowledge within the oceans and freshwater systems on Earth remains virtually untapped, because in the world of biological resear

Have Science Training, Will Travel
Jennifer Fisher Wilson | Jun 10, 2001 | 9 min read
In the early 1990s, just after Operation Desert Storm, scientists from the Walter Reed Army Institute of Research traveled to the lower Amazon basin to conduct trials with a new antimalarial medication. They found an epidemic in full swing among a camp of gold miners. The scientists labored in the humidity of the tropical rain forest to set up a clinic. But rumors slowed their progress: People said the researchers planned to develop medications, not for Brazilians, but rather for U.S. forces who
