https://phys.org/ en-us Latest news from Lehigh University Researchers with Lehigh University's Center for Catastrophe Modeling and Resilience, led by anthropologist David G. Casagrande, have identified two urgent challenges the United States faces in adapting to climate change: a potential disaster insurance crisis and the lack of comprehensive relocation policies for communities facing chronic flooding. Their paper, titled "Climate Change and Insurance: Embracing Resilience for Private Market Survival," is published in Sustainable Development. https://phys.org/news/2026-02-resilience-bonds-solution-climate.html Economics & Business Mon, 02 Feb 2026 15:56:35 EST news689270161 Atrial fibrillation (AFib) is a cardiac disorder in which the chambers of the heart beat rapidly and irregularly. It's the most common type of arrhythmia and the leading cardiac cause of stroke. https://medicalxpress.com/news/2025-10-personalize-neurostimulation-therapy-atrial-fibrillation.html Cardiology Wed, 29 Oct 2025 14:00:21 EDT news680956008 Bone marrow aspirate concentrate (BMAC) is a common treatment for joint injuries. The invasive therapy involves extracting bone marrow—often from the hip—and concentrating it to preserve stem cells and growth factors, which help promote wound healing and tissue regeneration. The concentrated mixture is then injected into the injury site to speed up tissue repair and reduce inflammation. BMAC can be used on its own or in conjunction with surgery to repair ACL, MCL, and meniscus tears and other injuries. https://medicalxpress.com/news/2025-10-hip-shoulder-bone-marrow-joint.html Surgery Mon, 20 Oct 2025 16:20:03 EDT news680196001 The results of the Lehigh Business Supply Chain Risk Management Index for the 4th quarter of 2025 indicate a decrease in risk, with eight out of ten risk categories showing a decline.
