Bird Lungs Reveal Extent of Airborne Microplastic Pollution
According to a new study, microscopic plastic pollutants are infiltrating the lungs of birds, raising concerns about potential risks to human health. Using laser direct infrared (LDIR) spectroscopy and pyrolysis gas chromatography-mass spectrometry (Py-GC-MS), researchers analyzed lung tissue from 56 birds spanning 51 species, detecting a high prevalence of microplastics and nanoplastics in the birds’ respiratory systems.
"Our research highlights an urgent need to address plastic pollution in our environments, as these contaminants can have far-reaching impacts on ecosystem health, as well as human health," explained Shane DuBay, an assistant professor of biology at UTA and study co-author, in a press release… Read more!
Looking Back, Moving Forward: With Deirdre Cabooter
Continuing our series of reflections on current and future trends in analytical science, Deirde Cabooter highlights how trends such as the rise of AI and increased accessibility to mass spectrometers are aiding the field’s growth.
“Another significant accomplishment is the development and increased accessibility of affordable, user-friendly, high-resolution mass spectrometers. These instruments have become more common in laboratories, which is fantastic because it means more people have access to high-resolution techniques and their improved sensitivities. One application I’ve found to be particularly fascinating is their use in real-time measurements, such as in operating rooms, where they’re used to make on-the-spot decisions on whether tissue is cancerous or healthy…” Read more!
Mass Action
Last Friday saw thousands of researchers, students, and allies of science take to the streets as part of the #StandUpForScience movement in opposition to recent rulings made by the US government. Their feeling of angst was one shared by Erin Baker, who spoke to us recently about her thoughts on the developments: “Ultimately, science cannot start to move forward again until order is restored, chaos is removed, and our researchers and thinkers are no longer under attack.”
Did you attend a local rally? Any thoughts on the news? We’d love to hear them.
