This so myopic. The covid mRNA vaccine that Pfizer made billions from was done by BionTech a company in Germany led by immigrant turks.

Sure some American's recently got the Nobel prize for the pseudouridine modification - and whiles that's enabling it's not sufficient - you also need LNPs and a whole bunch of other stuff to make it all work - some of which was invented in America and some of which wasn't.

The nature of international science is collaboration.

The danger the for the US right now is it's cutting itself off from one of the biggest sources of innovation right now - China.

I’m sorry, but you are completely missing the point.

Nobody disputed that mRNA, like all science, has many inventors. And that many people in the west as a whole has worked on the technology. Everything you said about the contributions to mRNA is correct, and doesn’t diminish US’s critical part in it.

The point was, and remains, that saying that the US has stopped becoming innovative, is just nonsense.

> Can you clarify what are you talking about? The US has been developing 6th-gen fighter since the mid mid-2010s - not that I'd consider it as an important new original invention.

So you think that, as an advanced military project that should have been kept under the strictest secrecy, the Chinese somehow obtained it and, based on that, developed their own sixth-generation fighter—and even managed a successful test flight while the U.S. is still at the PowerPoint stage? I don’t know which scenario would be worse for the United States.

Well, if we compare what we know about China's NGAD, which is almost nothing, with what we know about US NGAD, which is also almost nothing, we can safely conclude almost nothing.

You’re not wrong to think that way. But now there’s less and less left for China to “copy,” and it’s hard to argue that many things aren’t being invented by China itself.

Perhaps the real question is this: why is it that places that used to be technologically advanced no longer produce new, original inventions? Is it fear of China copying them? Did the U.S. decide not to develop a sixth-generation fighter jet because it was afraid China would copy it? Did it stop working on battery technology because it feared China would copy that too?

I'm actually liking 5.2 in Codex. It's able to take my instructions, do a good job at planning out the implementation, and will ask me relevant questions around interactions and functionality. It also gives me more tokens than Claude for the same price. Now, I'm trying to white label something that I made in Figma so my use case is a lot different from the average person on this site, but so far it's my go to and I don't see any reason at this time to switch.

I've noticed when it comes to evaluating AI models, most people simply don't ask difficult enough questions. So everything is good enough, and the preference comes down to speed and style.

It's when it becomes difficult, like in the coding case that you mentioned, that we can see the OpenAI still has the lead. The same is true for the image model, prompt adherence is significantly better than Nano Banana. Especially at more complex queries.

"Using newly-assembled data from 1980 through 2024, we show that 25% of scientifically-active, US-trained STEM PhD graduates leave the US within 15 years of graduating."

I believe there will be a significant "discontinuity" in the data beginning in 2025. Likely along the lines of (1) US-born science majors going abroad for their PhD's (and likely staying there afterwards), and (2) a major decline in foreign students coming to the US. Blocking disbursement of ongoing grants, immediate and dramatic slashing funding for the sciences, holding up universities under pain of blocking federal funding, eliminating fellowships, firing government scientists, stuffing agencies and commissions with politically appointed yes men, having oaths of fealty in all but name, deporting and blocking return of foreign students, and many more actions of similar character tend to fo that.

One of the greatest national scientific establishments was irreparably damaged in a matter of months. No discussion, no process -- just pulling the rug out. The US will coast for a few years on the technologies that just popped out of the university pipeline of development, but that pipeline is now essentially broken.

You'd very likely be wrong. People said the same thing in Trump's first cycle.

We tend to overestimate the short term effects due to polarization and the constant media cycle.

This is an area where hacker news shows its weakness. We have:

1. A chart showing a very low increase (1-2 percent)

2. Nothing to control scores rising in every school in America in the last school year (due to reduction of COVID effects).

3. Scores not moving immediately after the ban, but only after the start of a new school year, which means a new cohort of students muddying the data.

Yet the data fits people's biases here (regardless whether it's right or wrong), so the celebrate it and add anecdotes and explanations why it's true.

Too granular, there are 4 levels of wealth: the destitute, those who have to work, those who have enough assets to not work, and finally the elite who influence the rules of society.

gpt5 · a month ago

Those who have to work capture almost all of society.

It’s a little odd to clump everyone into the same bucket of wealth.

I can speak to this. I recently joined a community first responder association (I've always wanted to know what to do in case of a medical emergency) and was shocked to hear the members' horror stories of how long it can take an ambulance to arrive. Like the author, I grew up with the narrative "in trouble, call the ambulance, they'll scream through the streets to get to you in moments".

That might still be true where I grew up, in the US, but that's certainly not a guarantee in Melbourne, where I now live. On joining the local volunteer organization, I went from thinking "oh this will be a useful bonus for the community" to "wow, we can literally be essential". Since our org is composed of people living within the community, average response time to ANY call is <5 minutes (lower for cardiac arrest, when people really move). Sometimes one of us is right next door.

We can't do everything an ambulance paramedic can, but we can give aspirin, GTN, oxygen, CPR, and defibrillation. We can also usually navigate/bypass the usual triage system to get the ambulance priority upgraded to Code 1 (highest priority, lights + sirens, etc.) If for some reason the ambulance is far away (it backs up all the time), we can go in the patient's car with them to the hospital, with our gear, in case of further issues in transit.

I tell everyone now to always call us first (since our dispatcher will also call the ambulance) but while I feel more confident in how I'd handle an emergency, I feel less safe overall, with the system's faults and failings more exposed, and the illusion of security stripped away.

My condolences to the author.

In terms of updating - consider whether The System is really working. If not, what can you do yourself (or within your larger network) to better prepare...

Melbourne has an excellent ambulance response time (defined from the moment 000 call is received to when the first ambulance resource arrives on scene):

* Average Code 1 response time: 12 minutes 47 seconds

* Code 1 responses within 15 minutes: 77.2%

* Number of Code 1 first responses: 12,375

This places Melbourne among the faster councils in the state, and well ahead of the statewide average response time.

How does NovaMin / calcium sodium phosphosilicate compare to toothpaste with nanohydroxyapatite in it?

gpt5 · a month ago

It occludes dentinal tubules, helping reduce dentin hypersensitivity. It's a tooth-desensitizing agent helping people who are for example, very sensitive to very cold/hot temperature in their mouth.

There is evidence that it can foster enamel/dentin mineral gain, but head to head studies shows that it's comparable to regular fluoride toothpaste and not superior. E.g. In a randomized in-situ trial (Caries Research, 2017), adding 5% NovaMin to a 927-ppm SMFP toothpaste did not improve remineralization outcomes vs the same fluoride formula without NovaMin.

Also, you can find NovaMin in the US (e.g., NUPRO Sensodyne Prophylaxis Paste with NovaMin).
