New study charts the fate of chemicals affecting health and the environment

October 20, 2014

Looking forward in science often requires looking back, evaluating trends to extrapolate future outcomes. A classic case is Moore’s Law, which predicts that the density of components on an integrated circuit will double every 24 months. The estimate has helped guide many developments in the computer industry.  In a new study, Rolf Halden, PhD, a researcher at Arizona State University’s Biodesign Institute, examines the trajectory of chemicals appearing as emergent threats to human...

Fish tale: new study evaluates antibiotic content in farm-raised fish

October 20, 2014

Antibiotics—one of modernity’s great success stories—are charms that come with a curse. Their overuse in human and animal populations can lead to the development of resistant microbial strains, posing a dire threat to global health.  In a new study, Hansa Done, PhD candidate, and Rolf Halden, PhD, researchers at Arizona State University’s Biodesign Institute, examine antibiotic use in the rapidly expanding world of global aquaculture. Done and Halden measured the presence of...

Monitoring waste in groundwater (without all the waste)

March 7, 2011

The U.S. spends around 2 billion dollars a year on remediation at hazardous waste sites, with a large portion of this used for groundwater monitoring. Yet according to Rolf Halden, a researcher at Arizona State University’s Biodesign Institute, the information gathered is often of limited value. Under a new three-year, $1.15 million grant from the U.S. Department of Defense, Halden, assistant director at the Institute’s Swette Center for Environmental Biotechnology, is pursuing a novel...
