Health Secretary Robert F. Kennedy Jr. announced that Duchenne muscular dystrophy and metachromatic leukodystrophy have been added to the federal Recommended Uniform Screening Panel, a move hailed by advocates as a lifeline for earlier diagnosis and treatment. The policy shift follows the controversial disbanding of the expert committee that traditionally vetted new conditions, leaving states to decide whether to adopt the updated recommendations. At least two states already screen for Duchenne, suggesting a rapid rollout is feasible.

Night‑time Heart Attacks Cause Less Damage, Study Shows
A mouse study published in Journal of Experimental Medicine links the reduced severity of night‑time heart attacks to calmer neutrophil activity, echoing decades of clinical observation that daytime attacks inflict more cardiac injury. Analysis of over 2,000 patient records corroborates higher neutrophil counts and greater heart damage for daytime admissions, pointing to the immune system’s circadian rhythm as a therapeutic target. If translated to humans, timing‑based interventions could reshape acute coronary care.

Subclade K Influenza Variant Triggers Severe Cases
Scientists have identified a novel influenza strain, subclade K, as the driver behind a recent surge in severe flu hospitalizations across the United States and abroad. Epidemiologists warn that the variant’s mutations may evade existing vaccine protection, prompting calls for accelerated strain‑specific vaccine development. Public health agencies are monitoring its spread closely to inform upcoming flu season strategies.

Half of Heart Attacks May Slip Past Current Screening Tools
Research published in Science Alert suggests that nearly 50 % of heart attacks go undetected by conventional screening methods, highlighting a critical gap in cardiovascular prevention. The authors argue for integrating advanced imaging and biomarker panels to catch silent ischemic events before they become fatal. Such a shift could dramatically lower mortality rates if adopted widely.

Menstrual Cycle Extends Healing Time for Sports Injuries
A four‑year study of professional female football players in Spain’s Liga F found that injuries sustained during menstruation take significantly longer to recover than those occurring at other cycle phases. Researchers recommend tailored training adjustments—longer warm‑ups, modified workloads, and enhanced recovery protocols—to mitigate prolonged downtime. These findings underscore the importance of menstrual‑aware conditioning in elite sport.

Brain’s “Navigation Dial” Illuminated by VR Study
Using high‑resolution fMRI combined with virtual‑reality exploration, neuroscientists uncovered a “dial” in the brain’s navigation network that ramps up when participants traverse unfamiliar environments. The discovery, published in Nature Communications, may explain why getting lost is an early sign of dementia and could pave the way for novel diagnostic tools. Understanding this neural switch offers fresh insight into spatial memory disorders.

Boosting a Mitochondrial Protein Extends Mouse Lifespan
Scientists report that overexpressing a single mitochondrial protein in mice increases lifespan and slows age‑related decline, marking a promising avenue for anti‑aging therapeutics. The protein enhances cellular energy efficiency, reducing oxidative stress—a key driver of senescence. While still pre‑clinical, the results fuel optimism for translational research into human longevity.

FDA’s Digital Health Leaders Exit Amid AI Regulation Push
The Food and Drug Administration announced the departure of two senior figures from its Digital Health Center of Excellence, coinciding with congressional mandates for AI‑device oversight reports. Their exits raise concerns about staffing capacity as the agency grapples with emerging technologies like generative‑AI diagnostics and the new TEMPO pilot for chronic‑disease devices. Stakeholders warn that leadership turnover could delay critical regulatory guidance.

JWST May Have Captured the Universe’s Earliest Supernova
Astronomers using the James Webb Space Telescope propose that a powerful gamma‑ray burst detected in March originated from a supernova occurring just 730 million years after the Big Bang, potentially the most distant stellar explosion ever recorded. The event, labeled GRB 250314A, offers unprecedented insight into early star formation and the conditions of the nascent universe. If confirmed, the finding would set a new benchmark for JWST’s deep‑space capabilities.

Atmospheric Rivers Fuel Historic Flooding in Washington State
A series of moisture‑laden atmospheric rivers slammed the Pacific Northwest, delivering up to 18 inches of rain in days and breaching riverbanks across western Washington. Scientists link the intensified storms to a warming climate that allows the atmosphere to hold more water, turning once‑rare events into near‑annual threats. The resulting evacuations of over 100,000 residents and thousands of rescues underscore the urgent need for resilient infrastructure and climate‑adaptation policies.
