Memory chips tackle a precision problem.
Researchers demonstrated a memory-chip method for simplifying complex datasets while limiting accumulating calculation errors. Small hardware tests matched software accuracy; larger applications relied on simulations, leaving real-world speed and energy savings to be established.
Rapid heart ablation gets a one-year follow-up.
Field Medical reported one-year results from its first human trial of rapid electrical-pulse heart ablation. With the optimized pulse setting, 80% remained free of atrial arrhythmias. The investigational device still needs broader clinical evaluation.
A wrist-worn heart treatment returns mixed early results.
A 77-patient pilot tested wrist-worn nerve stimulation after heart ablation. StimCardio reported fewer recurrent arrhythmia events, but the difference in patients remaining arrhythmia-free was not statistically significant; larger trials must clarify benefit.
An inflammation drug enters a larger colitis trial.
Accro Bioscience says the first patient has received AC-101 in a placebo-controlled ulcerative-colitis trial. The study will test whether blocking an inflammatory signaling pathway improves remission after 12 weeks; efficacy remains unproven.
