For 70 years, we were told plastic was safe because it doesn't react with anything.
Nature just published proof that it does. And the trigger is water.
Researchers at Columbia University and UC Berkeley took six of the most common plastics on Earth.
Polyethylene. Polypropylene. Polystyrene. PVC. PET. Acrylic.
The stuff in your water bottles, food containers, pipes and packaging.
They ground them into microplastics and dropped them into plain water.
Nothing else. No sunlight. No chemicals. Just plastic and water.
And the water started changing.
At the surface of every single plastic, it began producing hydroxyl radicals. One of the most reactive and destructive molecules in chemistry.
All six plastics did it. Every one.
To prove it, they added a yellow dye to water with polystyrene. Over 10 days, nearly 90% of the dye was destroyed. The water turned almost clear.
In other liquids, the dye survived. Only water made the plastic active.
In plain English:
The plastic isn't leaking a toxic chemical.
It is turning the water around it into something that attacks.
Then they tested what that does to living things.
DNA and proteins got pulled onto the plastic surface like magnets.
Proteins started clumping together.
And red blood cells that touched the particles were torn into broken fragments.
But here is the twist.
The most dangerous plastics were the ones we trusted most.
Polyethylene and polypropylene, the "safe" plastics in bottles and food containers, were the most reactive of all.
The effect was weaker in blood serum. But it was still there.
And microplastics have already been found in human blood, brains, placentas and arteries.
The lead researcher said it plainly: "Water is a key active player here, rather than just a spectator."
We spent decades asking what chemicals leak out of plastic.
Nobody thought to ask what plastic does to the water inside us.
How many times have you sipped from a plastic bottle today?

you have a moral responsibility to educate your family & friends on what is going on in cyber rn.
it is only going to get worse/weirder from here.
here’s a great starter todo list to share:
PSA: in light of recent cyberattacks and vulnerabilities, I recommend everyone:
* use a good password manager (1Password) and do not duplicate passwords
* use two factor auth for everything important (not via sms!! Google Authenticator or better yet YubiKey)
* Auto-updates on, and restart weekly so they actually install
* Freeze your credit
* Get an IRS Identity Protection PIN
* Get your cell carrier to give you a port-out PIN or number lock that makes the carrier refuse to move your number without the PIN
You can ask your claude code to audit what on your laptop is out of date and needs updating.

Elon Musk: Neuralink's Blindsight vision implant is coming soon
"Even if somebody's completely blind, we can write directly to the visual cortex"
The first version will offer low-resolution vision, but the long-term goal goes much further:
"You would have very high resolution and be able to see multispectral wavelengths. You could see in infrared, ultraviolet, radar. It's like a superpower situation"

🤯 is what happened to my brain in my early 20s when I learned it runs on biases.
Distortions of reality I can’t see, touch, taste or smell.
I thought I was a rational thinker. 😬

To be demoralized is to have your sense of reality so inverted that you fail to recognize you are in a state of war, mistake those attacking you for victims, and willingly assist them in undermining your own society while believing you are doing something good.

a new paper published yesterday in Science Advances showed that just 10 minutes of ultrashort-wave stimulation significantly boosted the brain's waste-clearance system in mice
it amplified the brainwaves associated with deep sleep, even while the mice were awake
in mice with Alzheimer's pathology, just 7 days of treatment reduced amyloid buildup and improved memory
startup idea: a neuromodulation sleeping cap that supercharges your brain's nightly cleanup, improves sleep quality and potentially helps prevent Alzheimer's
i genuinely think we'll eventually figure out how to get a full night's restorative sleep in just 4 hours
imagine getting an extra 4 hours of life every single day without sacrificing your health
the implications are absolutely insane

The most dangerous myth in medicine is that aging is natural and therefore acceptable
Innovation in breast augmentation isn't as hard as you think.
Fat transfer is a safe and natural way without using implants.

Tesla's new Roadster hung almost upside down 65 feet off the ground, let go, and caught itself before it landed. The only thing it used to stop the fall was air.
Without the thrusters, that's a bad two seconds. From 65 feet, about six stories, a car hits the pavement doing roughly 44 mph. Nobody was inside. Elon said the car drove itself for the demo "to make sure we don't kill anyone."
Watch the readout in the bottom left as it drops. It jumps to 3.1 G at 31 feet as the thrusters fire, which is about how hard you get pressed into your seat at the bottom of a big roller coaster drop. While that's happening, attitude thrusters roll the car right side up and thrusters at the corners fire straight down to set it on its wheels.
The tanks hold about 250 kg of ordinary air, crammed into two carbon-wrapped pressure vessels totaling 600 liters, the same kind of tank SpaceX flies on its rockets. That works out to air roughly 340 times denser than what you're breathing, stored at several hundred atmospheres. Tesla says it leaves the nozzles faster than the speed of sound and the system puts out more than 80 kN, enough force to hold up over 8,000 kg.
The white cloud it lands in comes from the air too. Gas expanding that violently gets cold enough to turn the moisture in the night air into fog on the spot. Nothing on the car is burning.
And the tanks refill themselves. Elon says the Roadster can pump them back up on its own, which means the propellant for that six-story catch was the same air you're breathing right now.

When the editor of the world’s most prestigious medical journal concluded that much of the clinical research it published could no longer be trusted, the problem was no longer abstract.
Marcia Angell, a pathologist who joined the New England Journal of Medicine staff in 1979, rose to executive editor and then served as interim editor-in-chief from 1999 to June 2000. She stepped down after more than two decades at the journal, formally to write a book. The deeper context was her growing conviction, formed from years of editing manuscripts, that pharmaceutical industry influence had compromised the independence of clinical research. She and previous editors had enforced strict conflict-of-interest rules, yet industry-sponsored studies continued to arrive with designs, analyses, and selective reporting that favored the sponsor’s product. Negative results were often suppressed, side effects minimized, and “academic” authors frequently carried undisclosed financial ties.
In a widely cited 2009 New York Review of Books essay, Angell wrote the line that crystallized her position: “It is simply no longer possible to believe much of the clinical research that is published, or to rely on the judgment of trusted physicians or authoritative medical guidelines. I take no pleasure in this conclusion, which I reached slowly and reluctantly over my two decades as an editor of The New England Journal of Medicine.” She described an industry that had shifted from discovering useful drugs toward marketing, co-opting academic medical centers, researchers, and even the journals that were supposed to serve as independent arbiters. Her 2000 editorial “Is Academic Medicine for Sale?” and later book The Truth About the Drug Companies expanded the critique, arguing that commercial priorities systematically distorted what research was done, how it was conducted, and what reached publication.
Angell’s departure marked the end of an era of tighter editorial resistance to industry influence at the NEJM. Her public statements afterward made clear that she viewed the problem as systemic rather than isolated: once the bulk of clinical research depended on commercial funding, journals could no longer function as reliable filters of medical evidence.
A chance to reflect and prepare: How would you feel if the knowledge and skills you spent many years to master, was instantly available to everyone?
Progress is learning how to stand humbly on the shoulders of giants, even if those giants are robots
Reality check for mathematicians and doctors:
The purpose of 'math' is not to keep mathematicians employed, it's to solve problems and advance humankind's quality of life and understanding of reality.
The purpose of medicine is not to keep doctors employed. It's to prevent and relieve suffering caused by disease.
Yes, it's important that humans understand all the math and all the medicine.
But if AI can figure it out first, holding it back to protect the egos, prestige and income of the mathematicians and doctors is literally the opposite of the purpose of each field.
It doesn't matter who (or what) figured it out.
Just that it works.

THIS IS GENUINELY THE MOST TERRIFYING THING I'VE EVER WATCHED
they took the full wiring of a fruit fly, 166,700 neurons, and plugged it into an android hanging from the ceiling
the fly it came from has been dead for years
1,000 artificial muscles, a skeleton, no face
the fly brain was built for six legs and two wings
this body has two legs, two arms and nothing to fly with
nobody told it
> minute 1, a twitch in the fingers
> minute 4, the toes start curling like it's testing what it's attached to
> minute 9, the knees lift one after the other, it's trying to walk on air
> minute 20, someone walks underneath it and the kicking speeds up, you can hear the cables creak
> minute 31, the lights go off and every muscle locks at once
it found the rhythm a fly walks with and forced it onto human legs
and when the lights went off, it did exactly what a fly does when a shadow passes over it, it froze and got ready to launch
then came the part that made the room go quiet
> it brought both hands up to its chest
> started rubbing them together
> slowly, over and over
> the way a fly cleans itself
there is no code in that body that tells it to do that
it's 166,700 neurons doing what they've done for millions of years, inside a body they were never meant to have
right now the cables are the only thing holding it up
it learned to walk in one afternoon
nobody wants to find out what it learns in a month
and the next brain they're mapping is a mouse, 70 million neurons, about 400 times bigger than this one
Readers added context they thought people might want to know
This footage is Clone Robotics' Protoclone, which went viral in Feb 2025 twitching while suspended—before the fly connectome (MaleCNS) was released in Sept 2026. Protoclone has never been shown standing or walking unaided; it's suspended because it can't yet support itself. blog.robozaps.com/b/clone-protoc… livescience.com/technology/rob… ibm.com/think/news/fru…

Karl Deisseroth just won the Nobel Prize.
He showed that brain cells can be turned on/off by shining blue light on them, after inserting a light-sensitive protein from algae.
The method was named optogenetics and has been used worldwide to link specific neural circuits to behavior.
