The Iranian navy, which has been destroyed eight times, has apparently closed the Strait of Hormuz again, because the United States, for the seventh time, won the war that wasn’t a war, so now the United States has to open the Strait of Hormuz that was already open before the not-war began.

The not-war began because Iran had uranium that was totally, completely, beautifully obliterated, so they can’t build the nuclear bomb they weren’t building, which is why the United States had to start the not-war it definitely didn’t start.

Now the United States, which has nuclear weapons, is threatening to use nuclear weapons to stop Iran from getting nuclear weapons, because nuclear weapons are far too dangerous for countries with nuclear weapons to allow other countries to have.

If the United States saw the United States doing what the United States does in other countries, the United States would invade the United States to liberate the United States from the tyranny of the United States.

One of the most horrifying scenes in human history has been revealed.

When Israel forced thousands in Gaza to collect flour mixed with sand due to severe famine.

A moment the world must never forget.

[BladeoftheSun @BladeoftheS]

There's only 2 countries in the world with illegal unchecked Nuclear Weapons.

North Korea and Israel.

One of these countries has attacked 9 countries in the last 2 years and is committing a genocide.

It isn't North Korea.

The genocide seems unstoppable,
Necrocapitalism seems invincible- but they are not!

All we need is UNITY. COORDINATION. PERSEVERANCE.

Keep Protesting. Striking. Boycotting. Litigating.

Not just once.
All the times needed till the Apartheid ends and the system which fed it too.

The French hate air conditioning.

So Paris built a 120-kilometre machine under its streets for producing cold.

It’s called Fraîcheur de Paris, and it does for summer heat what district heating did for winter: centralise the problem.

Instead of every museum, office, hotel, hospital and shop bolting its own cooling plant onto the building, Paris moves cold through pipes.

The network sends water chilled to 2 to 4°C through buried supply lines. The water enters a connected building, absorbs heat through an exchange station, then returns at 12 to 14°C to be cooled again.

It essentially functions with two pipes. One carries the cold out, the other carries heat back.

The production plants cool the circuit from 12°C to 4°C. Some sites use the Seine as a heat sink. In colder periods, the system can use the river’s own temperature for free cooling, which means the machines work less and the electricity demand drops. The Seine water doesn’t become the building water. It stays separate, passing temperature across heat exchangers.

The scale is pretty strange when you see it written down though.

It's got 15 production sites, 4 storage sites, 120 km of underground network with 924 subscribers. This has resulted in 7 million square metres cooled, and 493 GWh of cooling sold.

A cold utility running beneath one of the densest cities in Europe.

The Forum des Halles has been cooled this way since 1979. The Louvre since 1986. Galeries Lafayette, Opéra Garnier, Hôtel de Ville, Station F, La Samaritaine and the National Assembly all sit on the same idea. Tourists stand in the Louvre looking at paintings while a municipal cold loop does part of the dull work below ground.

The boring part is the breakthrough.

Cold can be stored at night in chilled water or ice, then used during daytime peaks. The network is monitored from a control room with more than 125,000 control points. A delivery station inside a building takes 5 to 7 times less space than a standalone cooling installation and avoids the roof and façade clutter that turns cities into compressor farms.

That matters because conventional air conditioning solves heat by moving it somewhere nearby. In a dense city, thousands of private machines mean thousands of outdoor units rejecting heat into streets, courtyards and roofs, plus refrigerants, noise, vibration and maintenance spread across every building.

Paris’s public cooling network has a stated coefficient of performance of 4, against 3 for a wet standalone system and 2 for a dry standalone system. Against an equivalent set of autonomous installations, Fraîcheur de Paris says the network gives 100% higher energy efficiency, 35% less electricity use, 90% fewer refrigerant-fluid emissions and 50% lower CO2 emissions.

The climate backdrop is the real reason this exists.

Paris ran a full crisis exercise called “Paris at 50°C” in 2023. Météo-France’s 2050 reference trajectory for France points to heatwave days becoming five times more frequent, hot nights rising sharply in urban centres, and some local extremes around 48°C becoming possible.

The city signed a 20-year concession in 2022 with Fraîcheur de Paris, owned 85% by ENGIE and 15% by RATP. The contract is worth a projected €2.4 billion. The plan is to extend the network by 158 km by 2042, add 20 production plants and 10 storage sites, and reach more than 3,000 subscribers, including hospitals, nurseries, schools and care homes.

This is basically the infrastructure version of admitting that summer is becoming a public systems problem...

“The war in Gaza” is actually “the Genocide in Gaza”

“The war in Lebanon” is actually “the Genocide in Lebanon”

“Collateral damage and human shields” is actually “murder children and innocent civilians”

The media uses euphemisms to control the narrative. The media is complicit

[Parwiz Hamidi _🇵🇸 @Palestine001_]

This is extremely shameful when the whole world is silent and toothless on this.

🇦🇺 filmmaker Juliet said: I was raped by an Israeli soldier inside a darkened shipping container while handcuffed and shackled on a Gaza aid flotilla.

They also used water torture and beatings.

Hitler no empezó con campos.
Empezó con:
• Hacer Alemania grande de nuevo
• Prohibir libros
• Atacando a la prensa
• Culpando a los inmigrantes
• Creando enemigos de los vecinos
• Desfinanciando las artes
• Avivando el miedo a los
extranjeros
• Demonizando a los educadores

¿Suena familiar?

[Palestina En Español 🎒 @PalestinaVence]

🇵🇸 Susan Sarandon, ganadora del Oscar, rompió su silencio.

“Llamé a un alto al fuego en Gaza y me despidieron. Me borraron de las pantallas y me cerraron las puertas de grandes producciones.”

No es solo el caso de una actriz. Es la demostración clara de cómo funciona el sistema actual en Hollywood: quien habla por Palestina es castigado, mientras que quien guarda silencio o apoya la narrativa dominante es recompensado con contratos y visibilidad.

Esto revela un mecanismo de censura y presión económica muy efectivo: no necesitas prohibir la libertad de expresión, simplemente haces que tenga un costo altísimo.

Así se controla lo que se dice (y lo que no se dice) en la industria cultural más influyente del mundo.

Susan Sarandon se ha convertido en otro ejemplo de cómo se intenta silenciar las voces críticas, pero su testimonio sigue resonando.

¿Por qué pedir un alto al fuego en Gaza cuesta la carrera a una actriz de la talla de Susan Sarandon?

I interviewed Palestinian researcher Hala Hanina last year who introduced me to the term reprocide. Israel’s sexual torture is intended to destroy reproductive capacity and the ability for intimacy. Its deliberate nature makes it diabolical

[Cuban Embassy in US @EmbaCubaUS]

🇨🇺 Cuba has done it again.

Meet VAXIRA® — a therapeutic cancer vaccine developed by Cuban and Argentine scientists that helps the immune system recognise and destroy lung cancer cells. Approved in both Cuba and Argentina for advanced non-small cell lung cancer.

🔬 It works by mimicking a molecule found on cancer cells but almost entirely absent in healthy human tissue — meaning it targets tumours with remarkable precision and very few side effects.

📊 Clinical trials showed a significant improvement in survival for advanced lung cancer patients, with 1-year survival nearly doubling compared to the control group. Real-world data shows median survival of up to 24.5 months in maintenance therapy.

💉 Minimal side effects. Suitable for long-term use. Affordable and accessible — unlike many Western immunotherapies that price patients out of treatment.

And in 2025, VAXIRA® received Cuba's National Technological Innovation Award. All of this achieved by a country under decades of US economic blockade.

The United States spends billions on cancer research. Cuba, under sanctions, develops vaccines the world hasn't seen before. 🇨🇺🔬

You can crash your yard's mosquito population without spraying a single chemical with a Mosquito Bucket of Doom.

Fill a 5-gallon bucket about two-thirds with water. Drop in a handful of grass clippings, leaves, or hay. Let it sit for a day, then drop in a Bti dunk (also called Bacillus thuringiensis israelensis, sold at any hardware store as "mosquito dunks," about $10 for six).

Mosquitoes are powerfully attracted to fermenting water and will lay their eggs in your bucket. Bti is a naturally occurring soil bacterium that produces a toxin that kills mosquito, blackfly, and fungus gnat larvae only.

This method doesn't harm bees, butterflies, fireflies, fish, frogs, birds, pets, or people. BTI dunks are EPA-approved for organic use and safe in animal water troughs and birdbaths.

One dunk lasts about 30 days. Top off the water as it evaporates. Cover with 1/2-in Mesh Hardware Cloth to prevent animals from getting trapped and put the bucket somewhere shady where pets and kids won't get into it.

The bucket becomes a mosquito magnet and a dead end. Compare that to fogging the entire yard with pyrethroids, which kills every insect in it, including the predators that eat mosquitoes.

Doug Tallamy's Homegrown National Park has been running the "Mosquito Bucket Challenge" since 2021. The more buckets in a neighborhood, the bigger the dent. One bucket per yard is a great start.
