Nobel in Chemistry Awarded for Metal-Organic Framework Breakthroughs
The 2025 Nobel Prize in Chemistry has been awarded to Susumu Kitagawa, Richard Robson, and Omar M. Yaghi for pioneering work in designing and synthesizing metal-organic frameworks (MOFs)—crystalline structures composed of metal clusters linked by organic molecules, forming tunable porous networks. According to the Nobel Committee, their contributions have revolutionized how chemists build “molecular scaffolds” capable of capturing gases, catalyzing reactions, and selectively binding molecules. Their modular, “Lego-like” approach enables tailored materials for gas storage, carbon capture, and separation technologies. The committee also emphasized burgeoning biomedical and environmental applications: MOFs are being explored as drug-delivery vehicles, sensors, and scaffolds for catalysis and pollutant filtration. Their work bridges fundamental chemistry with real-world impact. (AP)
Former U.S. Surgeons General Demand Resignation of HHS Secretary Kennedy
Six former U.S. Surgeons General—Jerome Adams, Richard Carmona, Joycelyn Elders, Vivek Murthy, Antonia Novello, and David Satcher—co-authored an op-ed urging the removal of HHS Secretary Robert F. Kennedy Jr., warning his actions threaten national health. They claim his tenure has sparked mass resignations, undercut trust in agencies, and allowed resurgence of infectious and chronic diseases. The signatories argue Kennedy’s repeated dissemination of conspiracy theories and rejection of science have compromised core health institutions under HHS’s $2 trillion purview, including CDC, FDA, and NIH. Two psychiatric organizations echoed calls for his ouster, citing his rhetoric about mental health treatments. The authors insist leadership change is essential to prevent further destabilization of U.S. public health. (CIDRAP)
CDC pivots to “shared decision-making” for COVID shots; splits MMRV for toddlers
The CDC announced a shift from routine COVID booster recommendations to “individual-based decision-making,” emphasizing informed consent between patients and clinicians. Acting Director Jim O’Neill framed the change as restoring provider–patient conversations on risk–benefit tradeoffs. The agency also recommended giving the varicella (chickenpox) vaccine as a standalone shot for toddlers instead of the combined MMRV, citing safety/clarity benefits. Practically, Americans are now asked to consult their doctor or pharmacist about whether to take a seasonal COVID booster, a policy that may complicate uptake heading into respiratory virus season. The moves follow ACIP discussions elevating “shared clinical decision-making” across immunization schedules. Public-health groups are watching for impacts on coverage, messaging, and equity as fall vaccinations roll out. (CIDRAP)
Severe long COVID linked to surprisingly high rates of POTS
A Swedish study of 467 nonhospitalized adults with severe long COVID found that nearly one in three met criteria for postural orthostatic tachycardia syndrome (POTS), versus <1% in the general population before the pandemic. Most affected were middle-aged women. POTS, marked by rapid heartbeat on standing and orthostatic intolerance, can cause disabling dizziness, exercise intolerance, and fatigue. Researchers compared clinical features in long-COVID patients with and without POTS, suggesting tailored rehab and autonomic testing could improve care. The results underscore the heterogeneity of long-COVID sequelae and the need for multidisciplinary management, including cardiology and neurology. The findings appear in Circulation: Arrhythmia and Electrophysiology and add to growing evidence of dysautonomia after SARS-CoV-2 infection. (CIDRAP)
Oral GLP-1 pills show promise for weight loss, expanding beyond injectables
New clinical trials in NEJM report two oral GLP-1 drugs achieving double-digit average weight loss: high-dose oral semaglutide (25 mg) led to ~14% loss over 64 weeks (n>300), while Eli Lilly’s small-molecule orforglipron produced ~11% loss at the highest dose over 72 weeks (n>3,000). Pills may ease manufacturing, storage, and access compared with refrigerated injectables, potentially lowering costs and improving equity—though pricing and insurance coverage remain unknown. Side effects mirrored injectable GLP-1s (GI symptoms), with no liver toxicity seen for orforglipron. Experts say longer follow-up is needed to gauge durability and safety. If approved, daily pills could broaden obesity treatment alongside Ozempic/Wegovy-class injectables. (Science News)
RFK Jr. delay on fall COVID guidance sowed confusion; access mirrors last year
Ars Technica reports the administration’s weeks-long delay in issuing fall COVID vaccination recommendations—amid political controversy—left providers uncertain as virus season begins. Despite the turmoil, access pathways resemble last year’s: most people can get shots through local pharmacies and clinics, depending on supply and insurance. Public-health experts warn delayed messaging could depress uptake and complicate coordination with flu/RSV shots. The situation underscores how politicized decision-making can ripple through front-line logistics, even when the distribution infrastructure remains intact. (Ars Technica)
Ageing brains accumulate mutations in specific neuronal genes
A multi-age analysis of human brains (ages 1 to 104) reveals that somatic mutations accrue unevenly across neuronal genes, suggesting some loci are particularly vulnerable during healthy aging. The pattern may help explain why certain neural circuits succumb earlier to age-related decline or neurodegeneration. By profiling single-cell and regional genomic changes, researchers identified candidate pathways where mutation burden concentrates, offering targets for future studies and potential interventions. While the work does not establish causality for disease, it reframes aging as a mosaic genomic process within the brain’s cell types—and suggests biomarkers for “biological age” beyond simple years lived.

Simple clinic tools boosted early peanut-introduction counseling 15-fold
A randomized trial across 30 pediatric practices (290 clinicians; 18,480 infants) tested a package to promote early peanut introduction for allergy prevention: brief clinician training, EHR prompts, parent visuals, and a scorecard for eczema severity. Compared with controls, intervention sites documented guideline-adherent counseling far more often—84% vs 35% in low-risk infants and 27% vs 10% in high-risk infants—demonstrating that lightweight workflow nudges can move practice at scale. The study supports embedding decision support and parent education directly into well-child visits to curb peanut allergy prevalence—a strategy that could generalize to other preventive nutrition guidance.

Tiny pollution particles hitch rides on red blood cells, circulate body-wide
Scientists found direct evidence that traffic-related particulate matter (PM2.5) adheres to human red blood cells, potentially ferrying particles—and their metals—throughout the body. In a small crossover exposure study, volunteers standing near a busy London road had 2–3× more particle-laden RBCs versus indoor baselines; wearing FFP2 masks blunted the increase. Microscopy and elemental analysis confirmed particles containing iron, copper, zinc, and brake/tire-wear signatures. Lab experiments showed diesel particles stick readily to human and mouse RBCs. The mechanism helps explain how inhaled pollutants reach distal organs and strengthens arguments for both emissions mitigation and personal protective strategies for vulnerable groups.

Blood test flags head & neck cancer years before symptoms
Mass General Brigham researchers report a plasma assay that can detect head and neck cancers up to a decade before clinical presentation by tracking tumor-derived signals in blood. In early studies, the test showed high sensitivity and specificity, raising hopes for screening high-risk populations and enabling earlier, less invasive treatment. While larger, prospective validation is needed—and overdiagnosis risks must be weighed—the approach adds to the fast-moving field of “liquid biopsies” aiming to catch cancers at their most curable stages. If confirmed, such tests could integrate with routine checkups the way lipid panels do today. (scitechdaily.com)
