Regional Science Consortium Researching Harmful Algal Blooms
If you've noticed large buoys or boats out on the bayfront and wondered what they were, you're not alone. The Regional Science Consortium is collaborating with Princeton Hydro on a research project funded by the U.S. Army Corps of Engineers to study ways to control harmful algal blooms. Dr. Jeanette Schnars, the Executive Director of the Regional Science Consortium, explained the goal of the research."We are researching different ways to control blue-green algae, which creates harmful algal blooms and releases toxins," Dr. Schnars said.The project aims to identify potential techniques for controlling harmful algal blooms in Presque Isle Bay.Schnars explained that people may notice circular floats in the water near Perry's Landing and Liberty Park. Those floats are part of the testing process."You might see a circular float, almost like a hula hoop, that is out in the bay, near Perry's Landing and Liberty Park area, and those limn corrals go all the way to the bottom. And what we will do are some treatments within the limn corral in the bottom," Schnars said.After samples are collected, they are brought back to the laboratory at the Tom Ridge Environmental Center for analysis."A lot of those samples are coming back here. We are going to test them for the harmful algal bloom toxins before, during, and after, and see how effective the testing was," Schnars said.Sarah Magyan, an aquatic biologist with the Regional Science Consortium, explained that the team also collects samples from locations throughout the region."We pull samples every week from 30 different sites, and then we bring those back here, we preserve them and run them through the ELISA test," Magyan said.Schnars said researchers hope the results will help them develop effective ways to reduce harmful algal blooms in the future."If we can do some treatments over space and time in upcoming seasons, we may be able to reduce the number of harmful algal blooms we have in this area," Schnars said.The research is also important for public and animal safety. Magyan explained that toxins produced by certain algae can affect the skin, nervous system or liver.While toxin levels may be low for people, she emphasized the importance of protecting pets that swim in local waterways."Toxins can either be skin toxins, nerve toxins, or liver toxins. While we have low levels for people, it is important that we are keeping our pets safe because we recreate with our animals in the water, and we see hundreds and hundreds of dogs on Presque Isle and the rest of the shoreline," Magyan said.Testing began in September, and Schnars said researchers expect to conduct at least another six to eight weeks of testing to better understand the effectiveness of the treatments.

50 children in our area hit by cars every year; toxic pond water in Centennial Park; ‘gas station heroin’; plus other stories with Vanderbilt Health sources
In a news report following a Murfreesboro child who was killed by an automobile, reporter Amber Jayanth from WSMV Channel 4 News cited statistics gathered at Monroe Carell Jr. Children’s Hospital at Vanderbilt about pediatric pedestrian injuries. Trauma registry data from Monroe Carell indicates that about 50 children per year on average are treated after being hit by a car. William Schaffner, MD, Professor of Preventive Medicine, was quoted by several news outlets about public health issues, including: CNN (mRNA flu vaccine); ABC News and the American Journal of Managed Care (Pennsylvania measles outbreak); News Channel 5 (blue-green algae in the pond at Centennial Park, which can release toxins that make people and pets sick). WSMV Channel 4 News interviewed Saumya Aujla, MD, Assistant Professor of Clinical Physical Medicine and Rehabilitation, about the health risks of kratom, sometimes called “gas station heroin,” and why Tennessee banned the drug. WTVF News Channel 5 interviewed Brianna Smith, MD, Assistant Professor of Pediatrics, Hematology/Oncology at Monroe Carell Jr. Children’s Hospital at Vanderbilt for a piece on Childhood Cancer Awareness Month. Prevention interviewed Mitchell Gigandet, MD, Assistant Professor in the Neuro-Sleep Division, for a story about MDPI research on caffeine that used EEG imaging to see how the drug impacts sleep. It was found that caffeine may make sleep less restorative even when you fall asleep normally and stay in bed for eight hours. The Wall Street Journal reporter Laura Landro interviewed Joseph Schlesinger, MD, Professor of Anesthesiology Critical Care Medicine, for a story about ICU alarms keeping patients from getting sleep and creating alarm fatigue for nurses. Billboard reporter Melinda Newman interviewed country star Dasha about her upcoming vocal surgery at Vanderbilt Health. The story was picked up by numerous print and radio outlets including People.

In 2011, scientists injected yellow-green fluorescein dye into Maui’s wastewater wells; 84 days later, it appeared near the Pacific, supporting an underground wastewater connection
For years, environmental groups and residents near Lahaina, Maui, suspected that treated wastewater pumped underground was somehow finding its way into the Pacific Ocean, a concern later confirmed by a University of Hawaii tracer study that Earthjustice and other groups cited in their legal campaign against Maui County’s disposal practices. Divers had documented unusual submarine springs bubbling up off Kahekili Beach Park as early as 2007, and elevated nitrogen isotope readings in nearby macroalgae hinted that these springs carried something other than ordinary groundwater, according to USGS-led research on nearshore groundwater discharge at the site.

Killing slime: an AI-first biotech solution | Investors Lab
We love public science lessons, like the algae debacle that turned Washington, D.C.'s Lincoln Memorial Reflecting Pool a vibrant green this summer after a renovation. It's not exactly a new development. Algal blooms have intermittently plagued the site for generations, including during the last big overhaul in 2012. But the latest episode lingers despite treatments with hydrogen peroxide and an ozone nanobubble system. As Bethany Brookshire makes clear for Science News, there's another option that might have managed the crisis far more effectively, had it been used from the start.

A major climate hope in Antarctica just melted away
A popular climate theory suggested that melting Antarctic glaciers would release iron into the ocean, sparking algae blooms that pull carbon dioxide from the air. New field data from West Antarctica reveal that meltwater provides far less iron than scientists once believed. Instead, most of the iron comes from deep ocean water and sediments, not from the melting ice itself. The discovery raises new questions about how Antarctica influences climate change.
