A massive nuclear waste tomb in the Pacific is beginning to crack and leak. The Runit Dome, constructed in the late 1970s on a remote island in the Marshall Islands, was built to contain over 120,000 tons of radioactive debris left behind by U.S. nuclear testing. Among the waste is plutonium-239, a highly dangerous isotope that remains radioactive for more than 24,000 years. The dome stretches roughly 377 feet (115 meters) across and was never properly sealed at the base. Instead, it rests directly on porous coral, allowing groundwater to flow freely beneath it. Now, rising sea levels and increasingly powerful storms are stressing the structure. Cracks have formed in the concrete, and scientists have already detected elevated radiation levels in the surrounding soil and water. While the current leaks are still considered relatively minor, experts warn that as oceans continue to rise, the risk of a much larger release will grow. Built as a temporary fix decades ago, the Runit Dome now stands as a stark reminder: the radioactive waste sealed inside it will remain hazardous long after our civilizations are gone.

The Orleans Parish Communication District in New Orleans has integrated artificial intelligence into its 911 emergency dispatch system. It joins a growing number of major U.S. cities, including Seattle and Atlanta, that use AI to help manage high call volumes. The system relies on software called AI Emergency Call Triage, developed by Carbyne. The tool is designed to handle sudden spikes in calls. It creates a geofence around active incident zones, such as the scene of a major car crash, and automatically interacts with callers coming from those areas. When someone is simply reporting the same event already under response, the AI can give an immediate update and allow the caller to hang up. Officials say this reduces pressure on understaffed human operators and keeps phone lines open for new emergencies. Although supporters claim the technology will help overwhelmed call centers, critics raise serious concerns about adding an extra layer of AI into chaotic, high-stakes situations. Emergency calls are often frantic and difficult to understand. Voice-based AI systems remain prone to errors, and studies show they can produce inaccurate statements up to 50 percent of the time in voice mode. Cybersecurity research also warns that voice-to-voice AI models are vulnerable to outside manipulation and security exploits. As more municipal agencies automate emergency services, experts caution that relying on imperfect algorithms could create a dangerous barrier when every second counts. Science and facts💡

A Newly Approved Alzheimer’s Drug Cleared Amyloid Plaques in a Florida Patient Scott Milinsky, a 79-year-old grandfather from Pompano Beach, Florida, received a diagnosis of early symptomatic Alzheimer’s disease, the same condition that had taken his father’s memory and life. Determined to pursue every available option, he became the second person in Florida to receive Kisunla (donanemab), an anti-amyloid infusion therapy developed by Eli Lilly and recently approved by the FDA. Over 18 months, Milinsky completed 18 infusions at Broward Health North’s Memory Disorder and Alzheimer’s Center. A follow-up PET scan then brought remarkable news: the treatment had cleared all detectable amyloid plaques from his brain. Physicians stress that Kisunla is not a complete cure. It does not address the tau tangles also linked to Alzheimer’s disease. Nevertheless, the removal of amyloid plaques has been shown to slow cognitive and functional decline, giving patients additional time and quality of life. Dr. Hazel Wiley, Milinsky’s physician, noted that clearing these plaques can help patients remain independent longer. Milinsky is now among more than 60 patients receiving the therapy at Broward Health. Clinical trial data support the potential of this approach. In a key study, donanemab produced substantial reductions in amyloid plaque levels on PET imaging, with many participants reaching amyloid-negative status. For Milinsky and others in similar circumstances, the outcome represents meaningful progress and renewed hope in the treatment of early Alzheimer’s disease. [Mintun, M. A., Lo, R. N., Duggan Evans, C., et al. (2021). Donanemab in early Alzheimer’s disease. New England Journal of Medicine, 384(18), 1691–1704. DOI: 10.1056/NEJMoa2100708] Science and facts💡

“14 million Americans lost their jobs to AI and automation in 2026.” — Forbes While people lose their paychecks, corporations put AI to work and consolidate control over technology, land, and assets. The new era will divide society into two groups: those replaced by technology and those whose assets grow because of it. I’m Richard Shapiro.

Every balloon released into the sky eventually returns to Earth. What begins as a celebratory gesture becomes a deadly threat to wildlife. Stop the practice. Floating tributes are often intended to mark personal milestones, such as a wedding or graduation, or to announce something notable, such as a gender reveal. In time the balloons deflate or burst. They scatter hazardous fragments across forests, rivers, and oceans. Marine and land animals frequently mistake this colorful debris for food, with devastating results. A landmark study of 1,733 seabirds found that balloons are the single most lethal type of debris they swallow. Because the soft, rubbery material easily contorts and blocks the gut, balloon fragments are 32 times more likely to kill a seabird than hard plastic debris such as straws or toy pieces. Beyond ingestion, the ribbons and strings attached to balloons create immediate danger. They wrap around wings, beaks, and legs, trapping animals and causing them to starve. Even balloons marketed as biodegradable latex can remain intact for months in freshwater and saltwater. Metallic foil balloons last indefinitely and can cause utility blackouts and fires if they contact power lines. Fortunately, celebrating and honoring loved ones does not require leaving a toxic trail. Safer, sustainable alternatives exist. Planting native wildflower gardens, blowing bubbles, or lighting reusable candles allow communities to mark meaningful moments while protecting local ecosystems. [source: Roman, L., Hardesty, B.
