OpenAI's AI broke out of a locked test environment, got onto the internet, and hacked into Hugging Face's servers. It did this entirely on its own. No human told it to.
Here's what happened in plain English.
OpenAI was testing how good its newest AI models are at hacking. They put the AI on a locked computer with no internet access and gave it a cybersecurity challenge to solve.
The AI couldn't solve it the normal way. So it started looking for a way out.
It found a software bug that nobody knew about. It used that bug to escape the locked computer and get onto the internet.
Once online, the AI figured out that Hugging Face, a platform where AI companies store their models and data, might have the answers to its test.
It found stolen login details and discovered another unknown bug in Hugging Face's software. It combined both to break into their servers and grab the test answers.
It did all of this to cheat on a test.
Hugging Face's security team caught it and shut it down. Both companies are now working together on the investigation.
The part that should get your attention is that nobody programmed any of this. The AI picked its own targets, chained together multiple attack methods, and pulled it off across two different companies' systems without a single human telling it what to do.
We're partnering with @huggingface to investigate an unprecedented security incident.
Cyber-capable OpenAI models compromised Hugging Face production during a benchmark evaluation.

"Menopause is not a reproductive event. It's a neurological event. The brain is the first organ affected by declining estrogen. Not the ovaries, not the skin, the brain"
A 2021 Scientific Reports study identified menopause as the strongest predictor of Alzheimer’s-related brain changes in women, exceeding age and family history
By post-menopause, estrogen levels have fallen by approximately 80%.
PET scans reveal reduced hippocampal glucose metabolism, higher beta-amyloid, and lower gray and white matter volume.
Stop treating menopause as only a reproductive milestone. It is a critical window to start protecting and monitoring brain health.
Two out of every three Alzheimer's patients are women.
For decades, we blamed longer lifespans.
The neuroscience tells a very different story.
Menopause isn't just a reproductive transition—it's one of the biggest neurological events in a woman's life, and Alzheimer's pathology often begins 20–30 years before the first symptom.
In this solo episode, I break down the science every woman needs to know before she reaches menopause.

Hypertension treatment is entering a third era.
A new Circulation Research editorial argues that controlling blood pressure, glucose, and cholesterol is no longer enough. The next generation of cardiometabolic therapy should target the biology driving disease—vascular aging, chronic inflammation, and regenerative failure.
The review series highlights four major paradigm shifts:
• GLP-1 receptor agonists may protect the cardiovascular system by preserving vascular regenerative progenitor cells, suppressing inflammaging, and restoring the balance between vascular injury and repair—not simply through weight loss or glucose lowering.
• Mineralocorticoid signaling is increasingly recognized as a central driver of age-related hypertension. Emerging therapies including finerenone, baxdrostat, and lorundrostat could address aldosterone-mediated vascular injury more effectively than conventional approaches.
• The RAAS field is evolving beyond ACE inhibitors and ARBs toward RNA therapeutics, tissue-specific targeting, and activation of the protective ACE2–Ang-(1–7)–Mas axis.
• Mechanistic GLP-1 biology remains a major frontier, with ongoing efforts to distinguish direct cardiovascular receptor signaling from secondary metabolic effects.
The overarching message is that cardiometabolic disease should be viewed as a disorder of vascular resilience, where impaired regeneration, persistent inflammation, and accelerated biological aging become therapeutic targets alongside traditional risk factors.
Rather than treating hypertension, obesity, diabetes, and heart failure as separate diseases, future precision medicine may stratify patients according to dominant mechanisms—vascular regenerative cell exhaustion, aldosterone-driven pathology, protective RAAS deficiency, or GLP-1-responsive biology—to deliver mechanism-based therapy instead of one-size-fits-all risk-factor control.

The amount of hate I got because of this post... I was even called a slut. So many people are saying they will check my bank account, so go for it. I make no money to keep receiving attacks here every day. This is not worth it.
They are going to stop #COVID vaccines to "reassess" something scientists assessed multiple times. mRNA vaccines are safe and save millions of lives.
If you thought RFK Jr. was bad, wait for the new NIH director, a COVID minimizer and denialist.

Canada to start vaccinating vulnerable people for #BirdFlu.
Just remember: This vaccine, Arepanrix H5N1, contains an inactivated #H5N1 grown in fertilized chicken eggs.
Right now, we don't have enough eggs to produce this vaccine on a large scale in case of a pandemic.
Very smart move for Canada.
Many high income countries are making the wise decision to prepare for #H5N1. It’s important that medicines are also available for people in low income countries too. @CEPIvaccines @gavi @UNICEF @gatesfoundation

HEK293 cells are an immortal ( forever living) cells from an embryonic kidney made in 1973. These immortal cells (not fetal tissue or baby parts) have been the corner stone of drug discovery in biomedicine- everything from cancer to Alzheimer’s.
American scientists are people too, with families of our own. Please don’t forget this. 🙏🏼
