🚨 SCIENTISTS JUST USED ULTRAFAST LIGHT TO MAKE A 2D CRYSTAL’S SYMMETRY OSCILLATE IN PERFECT SYNC.

In a new Nature Materials study, researchers fired carefully tuned laser pulses at a 2D perovskite crystal and drove its atoms into synchronized collective motion so perfectly coordinated that the crystal’s own symmetry began to oscillate with the light.

Why this matters:
• Below the material’s bandgap, the pulses primarily drive lattice vibrations (phonons) rather than electronic excitations
• The crystal’s bandgap itself starts shifting up and down in a phase-locked rhythm tied to two coupled vibrational modes
• This creates a new form of light-controlled structural dynamics at ultrafast timescales

The deeper implication:
We are moving from passively observing materials to actively choreographing their atomic structure with light. Instead of just changing electronic properties, scientists can now make the physical lattice itself “dance” in a controlled, synchronized way.

This opens doors to ultrafast light-based switching, dynamic control of material properties, and potentially new classes of optomechanical and quantum devices.

What other fundamental properties of matter do you think we’ll eventually learn to control directly with light?

Siksi itse suosin mm. keittiöpinnoille suositeltua vain etanoliin ja isopropanoliin pohjautuvaa LV tuotemerkin ainetta.

Olen sumuttanut sitä paperinenäliinaan, jolla voi pyyhkiä näytön ja muut puhelimen pinnat ja koteloa.
Irrotetun kotelon (muovia) olen suihkulla puhdistanut pölystä yms.

The Toll of Pediatric Long COVID

An Infectious Diseases study shows children with long COVID face a symptom burden that meets or exceed other chronic health conditions. These children report worse fatigue and sleep issues than kids with cancer or autism.

Retinal microvascular alterations consistent with endothelial dysregulation in paediatric post-COVID-19 syndrome: A prospective matched-cohort study

🚨More “hidden” post-COVID damage in children!

Kids with long COVID show blood-vessel damage in their eyes, persistent, with partial & slow reversibility in some, still clearly abnormal months after one infection (retinal scans prove it)!

➡️German study design:
- Prospective matched-cohort; 58 children (7–17 yrs) with paediatric post-COVID-19 syndrome (chronic phase) vs. 58 healthy controls (matched age/sex/BMI),
- Retinal vessel analysis (static: CRAE/CRVE/AVR + dynamic flicker vasoreactivity) at baseline, and ~14-week follow-up,
- Single-infection chronic PCS kids,

➡️Main findings:
- Markedly wider central retinal arterioles (+28.1 μm, p<0.001) and venules (+21.7 μm, p<0.001) + higher AVR (+0.038, p=0.005), independent of BP or confounders,
- Pattern = endothelial dysregulation,

➡️Longitudinal changes:
- No overall group improvement at follow-up,
- Kids with largest baseline venular dilation & reduced flicker response showed greatest recovery,
- Longer follow-up + reduced symptoms → venular narrowing & AVR improvement,

➡️Implication:
- First in-vivo evidence of persistent microvascular alterations in paediatric PCS, detectable non-invasively,

➡️Conclusion (paper):
- “This study provides the first in-vivo evidence of altered retinal microvascular parameters in children and adolescents with PCS… persistent alterations in microvascular regulation several months after SARS-CoV-2 infection… heterogeneous, time-dependent changes… some patterns consistent with partial normalisation.”

‼️So paediatric post-COVID-19 syndrome causes long-lasting endothelial dysfunction in the microvasculature, visible months after infection, confirming a biological, vascular basis for kids’ persistent symptoms (not psychosomatic or transient).

This isn’t “mild” anymore. It never was!

This is measurable microvascular damage and remember: a second COVID infection DOUBLES their risk of Long COVID (Lancet Infect Dis 2026, RR 2.08).
