Consistent inactivity was the third most important risk factor for COVID-19 death, behind only age older than 60 years and previous organ transplant. It was more important than even smoking, obesity, diabetes, high blood pressure, cardiovascular disease... https://t.co/iqOgVQDnFA

Trump is giving $300 billion to Iran. This could pay for:

— Student debt elimination for 7.6M Americans
— An end to homelessness in America
— Healthcare subsidies for 22M Americans for nearly a decade
— Medicaid coverage for 3.2M Americans for a decade
— Food assistance for 41M Americans for 3 years
— Federal cancer research for 40+ years
— Free school lunch for every kid in America for over 4 years
— Replacing every lead pipe in America
— Free pre-K for every child in America for over 7 years

Y’all, not to be a huge nerd but for the reflecting pool you would need a minimum of about 8,000 liters of 12% hydrogen peroxide to reach the 50 parts per million concentration to kill algae…

Is this what happens when you have 0 scientists in your administration?

What a useless host the USA is for the World Cup.

For those wondering the visa bond implemented by the Trump admin against Cape Verde is $15,000 per person. Many players in this tournament are here without family or personal support because they literally cannot afford the visa.

I am horrified by last night's act of terrorism against Chicago Alderman Byron Sigcho Lopez, who is running for Congress as an independent socialist.

The devices were exploded outside his residence when his three children were asleep indoors.

The political establishment and the right wing are threatened by independent socialist candidates like Byron, who is calling for an end to funding for the Israeli state's genocide in Gaza, to abolish ICE, for universal public healthcare, and for taxes on billionaires to fund green jobs.

Working people and socialists must stand in solidarity against such acts of terror.

You see these scenes from Belfast?

That's our future if Reform, Restore, the Tories, GB News, Elon Musk and the right-wing media get their way.

Except this will be on a much bigger scale.

We have to decide: do we want those inciting hatred to destroy our country?

This Greek restaurant has no AC. It stays cool all summer on sea breezes alone, via fabric panels that scatter sunlight and move air around. Ancient Persians took the same principle so far they produced ice in 45°C (113°F) desert heat, without electricity.

The Persian wind catcher, known as a badgir (literally "wind catcher" in Persian), is one of the oldest cooling systems on earth. Archaeologists found evidence at Tappeh Chackmaq, a site near Shahrood, Iran, dated to roughly 3,000 years ago. They work on simple physics: a tower rises above the roofline, catches prevailing winds through angled openings, and funnels cooled air down into rooms below. Yazd, Iran still has 700 of them. UNESCO added the city to its World Heritage list in 2017, calling it "a living testimony to intelligent use of limited available resources in the desert." The Egyptians had their own version, the malqaf, shown in 1300 BCE artwork near Luxor.

Persians combined wind catchers with underground chambers to create the yakhchal, an ancient refrigerator. During cold desert nights, shallow pools of water froze solid. Badgirs then kept the chambers cold enough to store that ice through summer, in a desert regularly hitting 45°C. Inside, temperatures ran 15-20°C below the outdoor air, held there by thick insulating walls, steady airflow from the wind towers, and the cool ground beneath. This is how Persians made faloodeh, a frozen dessert, in a climate with no business producing frozen anything.

Willis Carrier designed the first modern air conditioning system on July 17, 1902, at a printing plant in Brooklyn. AC spread fast. Passive cooling vanished from new construction. Air conditioning and fans now consume 20% of global building electricity.

K-Studio, an Athens-based architecture firm, designed the Barbouni beach restaurant at Costa Navarino, Messinia. The fabric ceiling does two things at once: it breaks up direct sunlight before it heats the floor below, and its wave motion keeps air moving on top of basic convection (warm air rises, cooler outdoor air rushes in). K-Studio principal Dimitris Karampatakis: "We didn't want to have a static structure right in front of this dynamic landscape." Afternoon sea breezes at the Navarino coast arrive reliably each day, generated by land heating faster than the sea and drawing cooler air in from the water. The ceiling was designed around that daily rhythm.

Wind towers drop indoor temperatures by up to 22°F (12°C) with zero electricity and no maintenance. Yazd's badgirs have been running continuously for 700+ years. A Greek restaurant just did a simpler version, and 324,000 people acted like it was a new idea.

Mayor Mamdani criticizes Trump admin for handling of the World Cup, travel restrictions & visa denials for teams & others.

“The World Cup is supposed to be a celebration of the world as a whole… this is anathema to what this tournament is supposed to be about.”

Mamdani on World Cup US visa restrictions: "This is anathema to what this tournament is supposed to be about. If we can't even allow players, teams, journalists covering them to come to this country, it begs a larger question about our commitment to the spirit of this tournament"

This AI generated post is crap writing but has good information about the study.

[Nav Toor @heynavtoor]

You have noticed it. ChatGPT feels dumber than it used to. Your prompts that worked six months ago produce worse results now. The writing sounds flatter. The ideas sound safer. The internet itself feels like it is shrinking. Every article reads the same. Every email sounds the same. Every answer sounds like it was written by the same voice.

You thought it was you. It is not you.

Researchers at Oxford and Cambridge published a paper in Nature proving what is happening. They call it Model Collapse.

Here is the mechanism in one sentence. AI trained on AI-generated data gets dumber every generation until it forgets what real human data looked like.

The internet is filling with AI-generated content. Blog posts. Articles. Reviews. Comments. Social media. AI companies scrape the internet to train the next generation of models. Which means the next generation of AI is being trained on the output of the current generation.

Each cycle loses information. Not randomly. It loses the rarest, most unusual, most creative parts first. The researchers call these the "tails of the distribution." The weird ideas. The unexpected perspectives. The things that made the internet feel human. Those disappear first.

What remains is the average. The safe. The expected. The bland.

Then the next generation trains on that. And loses more. And the next generation trains on that. And loses more. The researchers proved this is not a slow decline. Major degradation happens within just a few iterations. Even when some of the original human data is preserved.

They tested it on large language models. On image generators. On statistical models. The pattern was the same every time. The output converges toward a narrow, flattened version of reality that looks nothing like the original data.

The lead researcher put it plainly. "Large language models are like fire. A useful tool. But one that pollutes the environment."

The pollution is invisible. You cannot see which sentence on the internet was written by a human and which was written by AI. Neither can the AI that is about to train on it. And once the tails are gone, they do not come back. The damage is irreversible.

This is not a prediction anymore. It is a diagnosis.

The internet you grew up on was built by humans writing things no algorithm would have written. Strange, personal, imperfect, alive. That internet is being diluted. One generation of AI at a time. And the models trained on what remains are learning a smaller and smaller version of the world.

Model Collapse is not a technical problem. It is a cultural one. The thing that made the internet worth reading is the thing that disappears first.

[JPA 🌞🔬🏒 @JPAsunset]

@adamross @heynavtoor Nah the writing is weak AF. It lacks an authentic tone.

[Nav Toor @heynavtoor]

4/ Even saving some real data does not fix it.

The researchers tried preserving 10% of the original human data in every generation. The collapse still happened. It was slower. But it still happened.

"Major degradation happens within just a few iterations, even when some of the original data is preserved."

The only thing that fully prevents collapse is training exclusively on human-generated data. The thing AI companies are running out of.

Morocco is the first country in the world to recognize Americas independence in 1776. Due to that, every July 4th in the Moroccan embassy in the USA and in the USA embasssy in Morocco there is a special ceremony recognizing our centuries old relationship. Go look it up.
Morocco also joins the Abram’s Accords. This is the slap in their face they get for being our longest standing allied nation.
