Study Finds Extreme Coastal Flooding Now 12 Times More Likely Due to Rising Sea Levels
A new study published in Nature Climate Change found that extreme coastal flooding events expected once every 100 years are now occurring about 12 times more frequently worldwide. The research, led by Tulane University, attributes this increase to human-caused sea-level rise. The findings underscore how climate change is fundamentally altering flood risk patterns that coastal communities have historically relied upon for planning and infrastructure.
Researchers at Tulane University published findings in Nature Climate Change demonstrating that human-caused sea-level rise has dramatically increased the frequency of extreme coastal flooding globally. Events that statistical models predicted would occur once per century are now occurring approximately 12 times more often on average. This shift represents a fundamental change in the baseline risk that coastal communities face, as historical flood frequency data no longer accurately reflects current conditions. The study's findings have significant implications for coastal planning, insurance, and infrastructure design, which have traditionally been based on century-scale flood probability estimates. As sea levels continue to rise due to ongoing climate change, these odds are expected to worsen further.

Study reveals IDH1 enzyme's role in cardiac metabolic adaptation during cancer-related stress
Researchers discovered that isocitrate dehydrogenase 1 (IDH1) helps the heart adapt to metabolic stress caused by cancer-related mutations through a previously unknown reductive metabolic pathway. The study used stable isotope tracing and genetic knockout models in rat and mouse heart tissue to show that when mitochondrial metabolism is impaired, IDH1 redirects carbon flux toward glutamine-derived citrate formation. This finding expands understanding of how cardiac metabolism responds to oncometabolic stress and may have implications for managing cardiovascular complications in cancer patients.
AI Framework Reveals How β-Arrestin 1 Protein Changes Shape During Activation
Researchers used a transformer-based artificial intelligence model to analyze how the β-arrestin 1 protein's tail region reorganizes when activated by cell surface receptors. The study examined molecular dynamics simulations comparing the protein in resting and active states, uncovering previously unknown conformational changes. This work could improve understanding of how cells regulate signaling pathways involved in numerous physiological and disease processes.
Study Links Pancreatic Cancer Tissue Stiffness to Tumor Progression and Patient Survival
Researchers combined imaging scans and laboratory tissue analysis to show that pancreatic cancer tumors with greater stiffness—driven by dense collagen buildup—correlate with worse patient survival outcomes. The study of nine patients found that magnetic resonance elastography, a non-invasive imaging technique, can detect mechanical properties that reflect underlying tumor biology. These findings suggest that measuring tissue stiffness through imaging could help doctors better characterize pancreatic cancer and guide treatment decisions.
