JCVI finally caved: every UK teenager around age 15 should get the MenB vaccine, reversing a decade of leaving 11-plus kids unprotected. The Kent outbreak earlier in 2026 — 29 confirmed or suspected cases and two deaths — exposed the gap so brutally that panicked parents started buying the jab privately at pharmacies. Two doses for the unvaccinated, one top-up for anyone who got it as a baby. The decision is a quiet acknowledgment that adolescents aren't a small-adult risk class. The heart story this week ran on a different axis: researchers at Fuwai Hospital in Beijing found Porphyromonas gingivalis, the gum disease bacterium, lodged in calcified aortic valves — and blocking IL-1β in mice stopped the damage cold.
The stories behind this week
What procrastinator are you - and how to fix it now (not later)For the roughly one in five who regularly procrastinate, the practical value is diagnostic: the real obstacle is usually an avoided emotion — anxiety, self-criticism, overwhelm — not laziness, and matching the fix (mindfulness for anxiety, task-scaffolding for overwhelm, self-kindness for guilt) to the underlying feeling makes breaking the cycle far more likely than generic productivity hacks.
Supplement that binds to microplastics may remove them from our bodyIf confirmed in larger trials, Qi601 would be the first consumer-accessible tool shown to intercept microplastics before absorption, but Wagner's critique reframes the public-health calculus: gut binding addresses one exposure route while airborne and dietary intake continue unchecked, making source-reduction of plastic pollution the more efficient lever.
Ancient Egyptian princesses buried with weapons may have been fightersThis is rare skeletal — not just symbolic — evidence that elite ancient Egyptian women trained in martial and hunting arts from a young age, complicating the 'decorative royal' stereotype. But the caveat from Zakrzewski matters: repetitive non-combat activities could mimic these bone signatures, so the 'princesses were fighters' framing rests partly on inference, not certainty.
Teenagers from 15 should be given free MenB vaccine, say UK expertsIf UK ministers accept the recommendation, every secondary school student would gain free protection against a disease that can kill within hours or leave survivors with amputations, hearing loss, or brain damage — closing a gap that has left more than a decade of adolescents unprotected since the infant programme began in 2015.
Venom-Derived Drugs: From Captopril to OzempicThe piece makes a conservation-meets-pharma argument: with roughly half of FDA-approved drugs derived from nature, the extinction crisis quantified in the column (18 soccer fields of tropical forest lost per minute, 85% freshwater decline) means potential blockbuster medicines are likely disappearing before researchers can screen them. For pharmaceutical companies and patients awaiting new therapies, the venom-to-pharmacy pipeline depends on species vanishing faster than drug discovery can keep pace.
Deaths from coronary artery disease have fallen, but more progress is within reachThe 88.8% preventable share means roughly 419,000 Americans died in 2023 from risk factors that public policy and clinical practice already know how to modify; the geographic clustering in Appalachian and Deep South states shows where structural interventions — tobacco policy, food environment, primary care access — would have to land hardest to close the gap.
Deepfakes impersonate doctors to sell unregulated treatmentsPatients and clinicians lose the foundational trust needed for safe care when digital authenticity can’t be assumed. Without verification norms, a single deepfake can trigger medication errors, erode accountability, and pollute medical literature—risks that scale faster than detection efforts.
Gum Disease Bacterium Found in Calcified Heart ValvesCAVS is a common, life-threatening valve disorder with no drug therapy — only valve replacement for severe cases — so identifying a modifiable risk factor like gum disease could open a low-cost prevention route, though the mechanism must first be confirmed in human trials.
Why it matters: The JCVI reversal closes a coverage gap that left every UK adolescent over 11 unprotected since the infant programme launched in 2015, meaning the next decade's worth of 15-year-olds will reach peak social-risk years with MenB immunity rather than pharmacy receipts.
