UK-led study reveals hidden massive star clusters deep inside nearby galaxies
Astronomers using the VLA and ALMA uncovered previously unseen giant star clusters, described as "ring factories," embedded within nearby galaxies. A complementary analysis of roughly 18,000 star‑forming regions showed that the energetic activity of young stars plays a decisive role in shaping galaxy evolution.

NASA’s First Medical Evacuation Is Here. It Won’t Be the Last.
NASA conducted its first-ever medical evacuation from the International Space Station in January 2026 when astronaut Mike Fincke experienced a microgravity‑related health event. The entire Crew‑11 returned early aboard a SpaceX capsule because no spare crew‑ready vehicle was available. The decision allowed Fincke to receive advanced imaging on Earth, while the remaining crew remained stable. This marks the first NASA mission ending prematurely for medical reasons, though Soviet missions performed similar evacuations in the 1980s.
Bay Area Light Sources Joint Users' Meeting
The U.S. Department of Energy’s three flagship light‑source labs—Advanced Light Source (ALS), Linac Coherent Light Source (LCLS) and Stanford Synchrotron Radiation Lightsource (SSRL)—will convene for their first joint users’ meeting at SLAC National Accelerator Laboratory from September 20 to 25,...

Understanding Schlieren
The article explains schlieren imaging, an optical technique that makes density variations in fluids visible. It focuses on a spherical‑mirror configuration that can render invisible gases, candle plumes, and shock waves detectable on camera. Sample images show carbon‑dioxide vortex rings...
Saving The Life We Cannot See
Scientists across the globe are sounding the alarm that microbes—tiny organisms driving half of Earth’s oxygen production and key carbon cycles—are under unprecedented threat. Long‑term monitoring programs such as the Bedford Basin Time Series reveal rapid shifts in microbial communities,...

Study Reveals Genetic Balancing Act Between Autoimmunity and Cancer Risk
Researchers at the Broad Institute and University of Helsinki analyzed over 81,000 individuals with autoimmune hypothyroidism (AIHT) and identified more than 400 genetic markers, including nearly 50 protein‑coding variants. The study distinguished genetic signals specific to thyroid autoimmunity from those...
Skeptical Science New Research for Week #9 2026
The latest Skeptical Science weekly roundup highlights mounting climate risks across multiple sectors. A new study finds 67% of U.S. national parks are vulnerable to transformative impacts such as fire, drought, and sea‑level rise, while research on extreme fire weather...
Curbing Methane Is the Fastest Way to Slow Warming – but We’re Off the Pace
The 2025 Global Methane Status Report finds human‑caused methane emissions have risen since 2020, though the increase is smaller than earlier forecasts. The Global Methane Pledge’s ambition has spurred national plans that could deliver an 8% cut by 2030, yet...
