Atrial fibrillation (AF) is the most common type of irregular heartbeat, and over time, it can worsen and become a permanent condition, a severe disorder that’s the leading preventable cause of ischemic stroke, according to the NIH. Nicolae Moise, a research scientist in the Department of Biomedical Engineering at Ohio State University (OSU), is using NCSA and OSC high-performance computing resources to explore the long-term progression of AF, in the hopes that his research can help with treatments that can stop AF before it becomes a lifelong condition.

Researchers have developed a transparent electrode made from embedding tiny silver wires into a transparent plastic matrix that can be simply deposited on top of conventional infrared detectors. This solves the engineering challenge posed by most materials that can conduct electrical signals but also block the majority of infrared radiation from reaching the sensor,

In a Policy Forum, Rishi Bommasani et al. argue that successful artificial intelligence (AI) policy must be grounded in solid evidence and scientific understanding rather than hype or political expediency. “AI policymaking should place a premium on evidence: Scientific understanding and systematic analysis should inform policy, and policy should accelerate evidence generation,” write Bommasani et al. Although developing sound AI policy hinges on clearly defining and effectively using credible evidence, the authors note that what is considered to be valid or credible varies across AI policy domains, leading to uncertainty in governance. This uncertainty creates a policy challenge: act too soon and risk overregulation; wait too long and risk real harm. Here, Bommasani et al. call for developing mechanisms that allow AI policy to evolve alongside emerging scientific understanding, which would ensure that governance remains both effective and grounded in the current state of the technology. To achieve evidence-based AI policy, the authors suggest that governments should incentivize rigorous pre-release model evaluations, increase public transparency around safety practices, and establish systems to monitor post-deployment harms. Protecting independent researchers through safe harbor provisions is essential to expand the evidence base. Policies should also prioritize interventions supported by strong evidence across the broader sociotechnical landscape. Finally, fostering expert consensus through credible, inclusive scientific bodies will help guide responsible AI governance amid uncertainty and disagreement, say the authors.
