UCLA scientists find that a single piece of gum could release up to 3,000 microplastic particles, raising concerns about an overlooked source of microplastic ingestion. Testing five brands of synthetic gum and five brands of natural gum, the researchers found an average of 100 microplastics released per gram of gum. “Our goal is not to alarm anybody,” said Sanjay Mohanty, lead author of the study and professor at UCLA Environment and UCLA Henry Samueli School of Engineering and Applied Science. “Scientists don’t know if microplastics are unsafe to us or not... But we know we are exposed to plastics in everyday life, and that’s what we wanted to examine here,” Mohanty told ConsumerAffairs. Learn more: https://lnkd.in/gefSRTUP

As part of of LA Climate Week, CTrees is hosting a free, in-person event on Thursday, April 10, focused on the future of natural climate solutions in California.

? Proud to celebrate the graduate students in my Issues & Methods Doctoral Seminar at the UCLA Institute of the Environment & Sustainability! Although the course is called "Issues and Methods," at its core, it is really about learning the methods to navigate the research process — step by step — as interdisciplinary scholars. Over the past quarter, these students have taken on the challenging work of identifying meaningful research questions, clarifying aims and objectives, designing methodologies, and grappling with the ethics of research, all while bridging disciplines to tackle some of today’s most complex environmental and sustainability issues. But just as important as developing a strong research proposal is learning how to speak across fields and build a community of scholars — and that is what makes this group so special. Together, these students have challenged each other, supported each other, and learned to engage with ideas beyond their own disciplines — embodying the collaborative, interdisciplinary spirit that makes IoES unique. This is the next generation of sustainability researchers — I am grateful to be part of their journey and I cannot wait to see where they take their work! ?????? Here’s a glimpse of the cutting-edge topics they are exploring: ?? Mapping the Landscape of Corporate Climate Strategies ?? Reframing Heat Exposure in Indigenous and Marginalized Communities ?? Improving Chaparral Wildfire Resilience through Conservation Finance ?? Restoring the Salton Sea for Bird Habitat Conservation ?? Rural vs. Urban Disparities in the Energy Transition ??

In a seminar at UCLA last Thursday, sci-fi legend Kim Stanley Robinson had a clear message: the fight for the future is real, and it’s happening now. He discussed economic levers that could drive a global energy transition, the fallout of defunding scientific research, and why surrendering to cynicism is the greatest risk of all. His seminar’s now available on the IoES website and YouTube channel.

1 in 5 butterflies in the U.S. have disappeared in the last two decades, according to a new study co-authored by UCLA ecologist Travis Longcore. Published today in Science Magazine, it reveals that over 100 species have lost more than half their populations—with 22 species losing more than 90%. The study is the largest, most in-depth butterfly population assessment ever conducted, analyzing over 76,000 surveys and 12.6 million butterfly records. Previous studies point to habitat loss, pesticide use, and climate change as key drivers of these declines. Key collaborators include scientists at Washington Department of Fish & Wildlife, Washington State University, and Xerces Society for Invertebrate Conservation.

?? Monday Roundup: What You Need to Know About the NOAA Layoffs ?? More than 800 meteorologists and staff at NOAA: National Oceanic & Atmospheric Administration were abruptly fired on Thursday—a move UCLA climate scientist Daniel Swain calls “reckless” and a threat to American lives. The layoffs, slashing nearly 10% of NOAA’s workforce, are “spectacularly short-sighted,” Swain warned. “There will be people who die in extreme weather events and related disasters who would not have otherwise.” NOAA houses the National Weather Service, the National Hurricane Center, and two tsunami warning centers—agencies that provide lifesaving forecasts for emergency responders, businesses, and the public. Swain warns the private sector “cannot quickly spin up” to fill the gap—leaving Americans more vulnerable to disasters. The dismissals are the latest in a wave of federal workforce cuts ordered by the Trump Administration via Elon Musk’s Department of Government Efficiency (DOGE). In response, the Union of Concerned Scientists issued an open letter to Congress and the Trump Administration, urging policymakers to intervene. “Without a strong NOAA, a cornerstone of the US scientific research enterprise, the world will be flying blind into the growing perils of global climate change,” the letter states. Nearly 150 scientists signed the letter, including UCLA IoES director Alex Hall, as well as IoES faculty members and researchers Daniel Swain, Paul Barber, and Brenda Larison. How do these cuts impact your field? If you work in emergency response, climate policy, or weather forecasting, share your perspective below. ??
