Home Our Mission Recycling Plastics Air Water Land Lifestyles Economy & Politics Media & Awards < Back Brewing Up Sustainability: How Beer Yeast Is Cleaning Our Waterways Local breweries in Chicagoland are turning beer waste into a water-cleaning solution, thanks to an innovative partnership with the Metropolitan Water Reclamation District (MWRD). A leading brewery, known for using Lake Michigan water in its beer, is repurposing spent yeast to help treat wastewater. Previously discarded down the drain, spent yeast—rich in carbon—is now collected and used to reduce excess phosphorus in treated water. High phosphorus levels can fuel harmful algal blooms, threatening aquatic ecosystems. MWRD's Stickney facility in Cicero now processes truckloads of yeast, turning waste into a resource. This initiative is part of MWRD's shift from wastewater treatment to resource recovery. Even extracted phosphorus is repurposed into fertilizer. Beyond yeast, MWRD may also accept grains, hops, and materials from food-processing facilities. The brewery’s participation not only supports sustainability but also cuts sewer fees, encouraging others in the industry to join. As recent events have shown, access to clean water isn’t guaranteed—responsible resource use is key. Since 2017, the resource recovery program has expanded, proving that sustainability and industry innovation can go hand in hand.

Home Our Mission Recycling Plastics Air Water Land Lifestyles Economy & Politics Media & Awards < Back 🦀 Horseshoe Crabs: The Ancient Creatures That Revolutionized Medicine 🦐 🦀 Horseshoe Crabs: The Ancient Creatures That Revolutionized Medicine 🦐 For over 450 million years, horseshoe crabs have roamed Earth’s oceans, surviving mass extinctions and remaining virtually unchanged. Despite their name, these marine arthropods are not true crabs but are more closely related to spiders and scorpions. While their prehistoric appearance is fascinating, it is their unique blue blood that has had a profound impact on modern medicine. The discovery of Limulus Amebocyte Lysate (LAL) , a crucial component of their blood, has transformed the way we ensure the safety of vaccines, injectable drugs, and medical devices. However, the increasing demand for their blood has raised concerns about their conservation. Horseshoe crabs ( Limulus polyphemus in North America, with related species in Asia) possess a primitive but highly effective immune system. Their blood contains amebocytes , specialized immune cells that detect bacterial endotoxins—substances released by harmful bacteria that can cause severe infections in humans. Scientists discovered that amebocytes could be used to create Limulus Amebocyte Lysate (LAL) , which reacts instantly when exposed to bacterial toxins. Today, LAL is the gold standard for testing the sterility of: Vaccines and injectable drugs Medical devices (such as surgical implants and IV drips) Intravenous fluids and prosthetics Without LAL testing, undetected bacterial contamination could lead to life-threatening infections, making horseshoe crab blood indispensable in modern medicine . A horseshoe crab Unlike human blood, which uses iron-based hemoglobin to transport oxygen, horseshoe crabs rely on copper-based hemocyanin , giving their blood a distinctive blue hue. This biological adaptation has allowed them to survive in low-oxygen environments for millions of years. Despite their vital role in medicine, the biomedical industry’s demand for horseshoe crab blood has raised concerns about declining populations . Thousands of horseshoe crabs are captured and bled annually, with some released back into the wild. However, studies suggest that a significant percentage do not survive or suffer long-term effects from the process. Overharvesting, along with habitat destruction and climate change, threatens these ancient creatures. To address this, scientists have developed a synthetic alternative to LAL called Recombinant Factor C (rFC) , which can detect bacterial toxins without relying on horseshoe crab blood. While rFC has been approved for use in some countries, widespread adoption remains slow due to regulatory challenges and industry hesitation. Horseshoe crabs, with their prehistoric origins and life-saving blue blood, play an irreplaceable role in modern medicine. As we continue to benefit from their remarkable biology, it is essential to balance medical progress with conservation efforts. By supporting sustainable harvesting practices and encouraging the use of alternatives like rFC, we can ensure that these ancient creatures persist for future generations while continuing to safeguard human health.

Home Our Mission Recycling Plastics Air Water Land Lifestyles Economy & Politics Media & Awards Scientists Map the Brain of a Fruit Fly, Neuron by Neuron First, imagine the level of precision required of the tools used to slice the fruit fly brain, about the size of a poppy seed, to map it neuron by neuron! Scientists from the FlyWire Consortium, led by researchers at Princeton University and the University of Cambridge, with contributions from institutions including the University of Vermont and support from the National Institutes of Health through the BRAIN Initiative, recently reached a major milestone in neuroscience by producing the most complete wiring diagram ever created for an animal brain: a full connectome of the adult fruit fly Drosophila melanogaster. This map offers an unprecedented look at how nearly 140,000 neurons and more than 50 million synapses are organized into circuits that support learning, memory, navigation, and flexible behavior. A connectome is a comprehensive chart of every neuron and every synaptic connection. Although a fruit fly’s brain is only about the size of a poppy seed, its circuitry is remarkably sophisticated. Creating this map required advanced imaging, artificial intelligence, and extensive human verification. Researchers first removed the fly brain and preserved it using fixatives such as glutaraldehyde and osmium tetroxide, which stabilize cellular structures. The tissue was then embedded in a hard resin and sliced into thousands of ultrathin sections, each roughly 40 nanometers thick, using an ultramicrotome equipped with a diamond knife. These sections were imaged with high‑resolution electron microscopes capable of capturing synapses and fine neuronal details. Millions of resulting images were reconstructed into a 3D model using AI‑based tracing tools. Because automated methods can introduce errors, researchers and citizen scientists in the global FlyWire collaboration manually reviewed and corrected the AI output, ensuring accurate mapping of neuronal pathways. The completed connectome allows scientists to trace information flow from sensory inputs through decision‑making circuits and onward to motor outputs. Even in this compact brain, researchers uncovered intricate and highly interconnected networks, demonstrating that small nervous systems can support far more complex computation than previously assumed. While mapping the fruit fly brain does not yet reveal exactly how behavior emerges from neural activity, it provides a foundational blueprint. Scientists hope that insights from this connectome will accelerate understanding of neural circuit function and guide future efforts to map larger and more complex brains.

Home Our Mission Recycling Plastics Air Water Land Lifestyles Economy & Politics Media & Awards LAND < Back Extremely High Levels of Plutonium, Comparable to Chornobyl, Found Near Los Alamos Lab Extremely High Levels of Plutonium, Comparable to Chornobyl, Found Near Los Alamos Lab Some of you may have watched the recent blockbuster, Oppenheimer, which tells the story of the birth of the atomic bomb at the Los Alamos National Laboratory in New Mexico. Near the lab is a canyon, now fully covered with lush greenery, that has become a popular recreational site. From 1943 until 1963, during the Manhattan Project and part of the subsequent Cold War era, liquid and often radioactive waste was dumped into this canyon, earning it the name Acid Canyon. Recently, a scientist from Northern Arizona University reported discovering extreme levels of plutonium contamination in Acid Canyon, comparable to those found at the Chornobyl nuclear disaster site in Ukraine. “What I found here in Acid Canyon is pretty much the most extreme plutonium contamination scenario…in an off-site, uncontrolled environmental setting that I’ve ever seen in my career,” says Dr. Ketterer of Northern Arizona University. This alarming finding has raised serious concerns about the extent of radioactive pollution in the area and its potential impact on public health and the environment. Plutonium, which was among the contaminants, has a half-life of 24,100 years, meaning it remains radioactive and hazardous for millennia. It is a highly toxic radioactive element that, if inhaled or ingested, can cause severe health issues, including lung cancer and other radiation-induced illnesses. The discovery has prompted calls for immediate action to clean up the contamination and ensure public safety. Local officials and residents are now demanding transparency and a comprehensive assessment of the contamination. Environmental advocates are pushing for stronger federal and state oversight of the laboratory's cleanup efforts, arguing that previous assessments underestimated the risks and that more stringent measures.
