Fabulous resource and fantastic to see clean air in schools brought into focus with 10 easy steps on how teachers and school leaders can improve health and learning by implementing these 10 simple strategies. Well done @twinklresources

💙So happy to share a BRAND NEW #CleanIndoorAir educational resource! 💙 @twinklresources just published this fabulous resource which highlights how crucial clean air in classrooms is. Please share! 🙏 @erbrooker @_CatintheHat @Lessnessprimary #EduTwitter twinkl.co.uk/resource/leadin…

We do too! Every classroom should have one! ventilation air purifiers = healthy air

Incredible speech delivered by Baroness Linforth in the House of Lords today calling for clean indoor air in schools. “It would cost less than a tenner per child per year to provide pupils and staff with clean air - about the same cost as a coffee and a cake.” ☕️🧁

Well done Róise

We got a message this week from Róise, a student who completed her project on air quality in primary school classrooms at Scoil Naomh Bríd in Muff, Donegal and found Smart Air along the way. She said she wishes her own school had air purifiers... 💙 x.com/SmartairUk/status/2052…

GO AQS (Global Open Air Quality Standards) is proud to announce the introduction of GO IAQS for Schools, a strategic plan designed to transform educational environments from passive shelters into active, health-protective zones. 🔗 goaqs.org/go-iaqs-for-school… #IAQ

Damn, that’s wild—Harvard stuck 24 office workers in the same room for 6 days, secretly tweaking the air quality (ventilation, CO2, and VOCs from typical office stuff), and their cognitive scores doubled in the cleaner “green ” conditions vs. standard stale setups. Better decision-making, strategy, crisis response—all crushed by poor indoor air we breathe 90% of the time. Open windows, crank ventilation, cut the junk emitters. Your brain’s paying the price right now. Fix the air, sharpen the mind.

If filtration is good enough for schools in London, why not everywhere? Clean indoor air should not depend on postcode. It is a basic public health measure for every child. go.corsirosenthalfoundation.… #CleanAir #CleanAirInSchools #AirQuality #HealthEquity

"Children whose mothers had COVID-19 during pregnancy show an altered brain structure and different behavior. COVID-19 will sustainably change our society because both adults and children feel less empathy and are less able to anticipate."

Long COVID hasn’t disappeared. People continue to develop it after new infections—yet the myth that it’s “over” still persists. Bára’s story shows the reality: after her 3rd COVID‑19 infection in 2025, she became house‑bound with severe fatigue and heart issues.

A groundbreaking study has pinpointed a microscopic culprit behind the debilitating fatigue, brain fog, and other persistent symptoms of long COVID: abnormal, sticky microclots embedded with neutrophil extracellular traps (NETs) in patients' blood. These microclots—tiny aggregates of clotting proteins—are small enough to obstruct the body's tiniest blood vessels (capillaries), restricting oxygen delivery to tissues and organs without triggering obvious large-scale clotting events. In long COVID patients, researchers observed a dramatic ~20-fold increase (median 19.7 times higher) in the number of these microclots compared to healthy controls, with the clots also tending to be larger. What sets this finding apart is the discovery that these microclots are structurally intertwined with NETs—web-like structures of DNA, enzymes (such as myeloperoxidase and neutrophil elastase), and proteins released by neutrophils (a type of white blood cell) to ensnare pathogens. Normally, NETs form temporarily and then dissolve, but in long COVID, they persist and become physically embedded within the microclots, creating highly resistant, "gummy" structures that evade the body's natural clot-breaking processes (fibrinolysis). This creates a chronic thromboinflammatory state, where blocked microcirculation and ongoing low-grade inflammation may sustain symptoms like exhaustion and cognitive impairment. The differences were so pronounced that machine learning models analyzing anonymized blood samples (via fluorescence microscopy for markers like ThT for amyloid-like structures, DNA stains, and MPO for NETs) could distinguish long COVID patients from healthy individuals with 91% accuracy—offering a potential objective biomarker for a condition that has long evaded reliable diagnosis through standard tests (e.g., normal D-dimer, PT/INR, or aPTT levels despite significant microclot burden). This work, led by teams including Prof. Etheresia Pretorius (Stellenbosch University) and Dr. Alain Thierry (Montpellier University), reframes long COVID as a tangible, blood-based disorder driven by dysregulated coagulation and innate immunity rather than vague "post-viral malaise." Targeting NETs or microclots—perhaps with therapies to degrade NETs or prevent their stabilization—could open doors to treating root causes instead of merely alleviating symptoms. [Thierry, A. R., Usher, T., Sanchez, C., Turner, S., Venter, C., Pastor, B., Waters, M., Thompson, A., Mirandola, A., Pisareva, E., Prevostel, C., Laubscher, G. J., Kell, D. B., & Pretorius, E. (2025). Circulating Microclots Are Structurally Associated With Neutrophil Extracellular Traps and Their Amounts Are Elevated in Long COVID Patients. Journal of Medical Virology, 97(10), e70613.

Attendance is critical for students to do well in school. A cheap way to increase attendance: clean the air!! Check out the success story below. We have solutions. We need to use them. @erbrooker @CleanAir4KidsUK
