That twig is a pharmacy and the chemistry explains why his teeth look like that.

Miswak comes from the Salvadora persica tree. When you chew the end and fray the fibers, you're releasing benzyl isothiocyanate, which makes up 68 to 86% of the plant's essential oils. That single compound kills Streptococcus mutans, the bacterium responsible for most cavities. A nylon toothbrush has zero antimicrobial activity on its own. You need toothpaste for that. The twig comes preloaded.

But benzyl isothiocyanate is one of roughly 20 bioactive compounds in the wood. Natural fluoride remineralizes enamel. Silica acts as a gentle abrasive that removes surface stains without stripping enamel the way peroxide whitening does. Tannins tighten gum tissue and reduce inflammation. Vitamin C accelerates gum repair. Sulfur compounds bind to the teeth and mucosa and keep working for hours after you stop chewing.

The saliva effect is the part most people miss. Chewing miswak triggers a spike in salivary flow. Saliva neutralizes acids, washes out food particles, and delivers calcium and phosphate back to tooth enamel. Within minutes, the pH of your mouth shifts toward an environment where cavity-causing bacteria can't thrive. The twig handles offense (killing bacteria) and defense (buffering your mouth chemistry) simultaneously.

A study of 203 Sudanese adults found 53.3% caries prevalence among regular miswak users versus 76.9% among toothbrush users. A meta-analysis of clinical trials found miswak reduced plaque and gum inflammation to levels statistically comparable to brushing with a conventional toothbrush and toothpaste. The WHO formally endorsed it for oral hygiene in 1987.

Babylonians and Egyptians were using frayed twigs to clean their teeth by 3500 BC. Five thousand years later, Colgate put the same functional ingredients, fluoride, silica, and antimicrobials, into a tube and called it innovation.

Harvard scientists ran a simple test. They put adults under blue light for 6 hours one night, then under green light at the same brightness the next. Blue light pushed their bedtimes back by 3 hours. Green pushed them back by 1.5. And in kids, the same lights hit about twice as hard.

The reason comes down to a tiny patch of cells at the back of every human eye. These cells have one job. They tell your brain whether it is day or night. They wake up most when light hits a very specific shade of blue, the same shade phone screens and modern bulbs are loaded with. When those cells fire after dark, the brain stops making melatonin, the chemical that pulls you toward sleep.

Red light barely sets off those cells at all. A 2025 study from the University of Zaragoza put people under red lamps and blue lamps for three hours at night. Under blue, their melatonin stayed scraped to the floor. Under red, it climbed back up to more than three times higher. Same brightness. The color did all the work.

Children get this worse than adults. Two reasons. Their pupils are bigger, so more light gets in. And the lens inside a kid's eye is still glass-clear, where adult lenses slowly yellow with age and filter blue out naturally. A 10-year-old's body clock is roughly twice as sensitive to evening light as a 45-year-old's. A bedside lamp that feels harmless to a parent can be wrecking a kid's sleep clock at the same time.

Then there is the lag. Once the brain catches a dose of blue light, the wake-up signal it sends out keeps echoing for 3 to 4 hours after the lights go off. So a kid on an iPad at 9pm can still be wired at midnight even if you took the iPad away at 9:01.

Modern LED bulbs and screens are tuned to roughly 6500 Kelvin. That is sunlight at noon. Old incandescent bulbs sit around 2700, mostly red and yellow with almost nothing in the blue range. To a human eye, a red-lit room is just about as close to no light at all as you can get. The brain reads it as nighttime.

The fix is boring. Use warm bulbs at 2700 Kelvin or lower in any room a kid spends evenings in, switch off phones and tablets two hours before bed, and if a night light is needed for bathroom trips, make it red or amber. The science was pinned down to the exact color of light back in 2001.

@maurizio_crippa @LucaBizzarri Poichè gli assistenti sociali sono vincolati al segreto professionale e non possono spiegare le proprie decisioni, qualsiasi affermazione sulla loro competenza è viziata in partenza. Ma tanto il punto non è quello, ma creare un caso che coinvolga i magistrati a 15 gg dal voto.

Minaccia Groenlandia, Canada e Cuba. Rapisce Maduro. Disprezza e insulta l’Europa. Appoggia i neonazisti tedeschi e il putinista Orbán. Dà carta bianca a Netanyahu. Molla l’Ucraina per aiutare Putin. E ora scatena una guerra contro l’Iran. Questa è l’America di Donald J. Trump.

Questa Ve la dovete leggere tutta.
Massa di coglioni che andate dietro alle cazzate di Salvini e questo governo di farabutti.

"Vi ricordate la storia del poliziotto che ha sparato a un ragazzo durante un presunto controllo antidroga nel boschetto di Rogoredo, a Milano? Un colpo alla tempia e una pistola trovata accanto al corpo.

E vi ricordate, subito dopo, il post di Salvini?

“L’agente viene indagato per omicidio volontario. Tutto sbagliato! Nel nuovo pacchetto sicurezza abbiamo previsto una norma che eviti che gli agenti vengano automaticamente indagati dopo essersi difesi. Io sto col poliziotto”.

Vi ricordate le card, la raccolta firme, la solidarietà all’agente che “ha fatto il proprio dovere difendendosi” da un “nordafricano irregolare che si avvicina puntando una pistola”?

Ecco, è arrivata la verità.

Abderrahim Mansouri, 28 anni, non era armato.
Al punto che, sulla pistola, la scientifica non ha trovato le sue impronte.

Non le ha trovate perché non l’aveva mai toccata. Non l’aveva mai impugnata.
Non l’aveva mai puntata contro nessuno.

La pistola, secondo gli inquirenti della Procura di Milano, è stata portata lì e posizionata accanto al cadavere da un collega dell’agente che ha sparato. Messa lì dopo il colpo alla tempia.

Mentre Mansouri agonizzava a terra, i quattro agenti presenti hanno aspettato più di venti minuti prima di chiamare i soccorsi.

Poi, sentiti dagli inquirenti, hanno mentito su tutto: sulla sequenza dei fatti, sulla posizione di ognuno, sulla presenza di altre persone, sui tempi.

E Salvini, quel giorno, non aveva aspettato niente. Aveva letto “nordafricano” e “poliziotto” e gli era bastato.

“Io sto col poliziotto”.

Con quale poliziotto, Matteo?

Con quello che ha sparato a un uomo disarmato?

Con quello che gli ha messo una pistola finta accanto al corpo?

Con quelli che lo hanno lasciato agonizzare per venti minuti senza chiamare un’ambulanza?

Con quelli che poi hanno mentito agli inquirenti su tutto?

Con quale poliziotto stai, Matteo?

Perché ci sono migliaia di poliziotti in Italia che fanno il loro lavoro ogni giorno, che rischiano la pelle, che meritano rispetto e tutele vere. E poi ci sono quelli di Rogoredo.

E tu hai usato quelli di Rogoredo, con un uomo disarmato ammazzato con un colpo alla tempia, una pistola finta piazzata accanto al corpo, venti minuti senza soccorsi, un muro di bugie, per farti la campagna elettorale.

“Il balordo muore. Io sto col poliziotto”.

Questo ha scritto il vicepremier della Repubblica italiana. Di un ragazzo disarmato, ammazzato e poi incastrato con una pistola che non era la sua.

E la raccolta firme è ancora online."

BREAKING: Mayor Zohran Mamdani SLAMS Donald Trump for illegally invading Venezuela, kidnapping President Nicolás Maduro, and flying him to New York in a blatant act of "regime change."

Maduro is expected to face charges in Manhattan federal court next week...

"I was briefed this morning on the U.S. military capture of Venezuelan President Nicolás Maduro and his wife, as well as their planned imprisonment in federal custody here in New York City," Mamdani wrote on X.

"Unilaterally attacking a sovereign nation is an act of war and a violation of federal and international law," he continued. "This blatant pursuit of regime change doesn’t just affect those abroad, it directly impacts New Yorkers, including tens of thousands of Venezuelans who call this city home. My focus is their safety and the safety of every New Yorker, and my administration will continue to monitor the situation and issue relevant guidance."

This is what real American leadership and moral clarity looks like. Meanwhile, Trump has justified his lawless attack on Venezuela by smearing Maduro as a drug kingpin, but the truth is that he wants to seize that nation's vast oil reserves for his fossil fuel donors. At the same time, this new cycle serves as a distraction from his worsening Epstein scandal.

The actual charges arrayed against Maduro by the MAGA Justice Department are laughably absurd. In addition to the baseless accusations of narcoterrorism, Pam Bondi has announced that Maduro will be charged with possession of a machine gun. The White House isn't bothering to give this farce even a pretense of credibility. It's naked imperialism and gangsterism.

Please ❤️ and share if you oppose the attack on Venezuela!

I watched the Stranger Things finale today in a packed theater with my family. It was quite a scene. There were tons of people wearing merch, just so excited to see how the thing ends. And by the time the credits rolled, it was pretty clear that everyone loved it. There were big cheers, big laughs and lots of tears (not from me tho I'm tough 😤). I talked to my real life friends afterwards and they also seemed to enjoy it. I was honestly moved by how cool of a moment this was. An original idea that grew into a worldwide phenomenon that so many people loved. AND they gave us a solid ending. How cool is that? How rare is that? Will we ever see something like that again?

Then I check Twitter...

And it was just lots of negative commentary from people who seem to get off on hating on things that normal people enjoy. And that's when it hit me.

Twitter is our upside down. It's a lot like real life but much darker and full of negativity. Trolls are demogorgons. Elon is Vecna. And all of us are just trying to live our lives in peace with our friends.

In conclusion: Stranger Things is a really fun show and I'm grateful for all the good times it gave my family. I honestly think we grew closer bc of it. Shoutout everyone who was involved in making it.

PS: I'm clearly Steve in the analogy above.

Anna’s Archive: cos’è e perché conta.
È un meta-motore di ricerca open source che indicizza e rimanda a contenuti presenti in diverse shadow libraries (come LibGen, Sci-Hub, Z-Library).
In pratica non nasce come “sito di un singolo catalogo”, ma come infrastruttura di ricerca e accesso a un enorme archivio distribuito di libri e paper, spesso presentata come progetto di “preservazione”.

Ma non è (solo) la solita storia di “pirateria romantica”.
Nel nuovo articolo smonto il mito del Robin Hood digitale e racconto per ciò che rischia di essere davvero: un’infrastruttura industriale dove la cultura diventa materia prima, “ripulita” e resa sfruttabile per addestrare modelli di Intelligenza Artificiale.

Dai numeri che fanno impressione al meccanismo del data laundering, fino alle conseguenze più dure: chi paga il prezzo non sono i big, ma la classe media creativa.
