I use ultrasound many times every single day in the ICU, but there’s a lot of unreasonable hype about this “whole body imaging” ultrasound. I’m very skeptical of the claims being made and I’ll explain why:
First some fundamental limitations of US:
Ultrasound doesn’t penetrate bone and doesn’t pass through air very well. This makes imaging the brain and lung parenchyma essentially impossible with US. Bowel gas also frequently makes it difficult to visualize abdominal structures like stomach, small bowel, colon. It can’t see into bone either which can limit its utility for musculoskeletal imaging. For this reason ultrasound isn’t really amenable to a “whole body scan.” It’s hard to see how this could replace other modalities (MRI, CT) if it can’t visualize so much of the body.
Ultrasound exams are often dynamic. If you’ve had one you may have been asked to roll or move to visualize certain structures. This requires a skilled operator. Immersing the patient in a tank for a 1 minute scan is a cute shortcut. It’s technically easier but it probably won’t be able get optimal images, further limiting interpretation. Also are they exchanging the water in the bath each time? Much of the time spend on imaging is actually cleaning the scanner between patients. Unclear how you can quickly disinfect a liquid scanner.
The theoretical resolution of ultrasound is very high, but that isn’t quite the same thing as being able to identify structures. There are lots of artifacts and limitations to ultrasound. For some organs (thyroid, kidney, liver) it’s great. For others it may be less so (pancreas, colon, stomach, etc). Hard to see this replacing existing methods, especially if the concern is cancer screening.
Ultrasound isn’t really one modality. There are a lot of different techniques (B mode, M mode, 3d modes, different types of Doppler, etc). Unclear how many of these this gizmo can do. Adding these capabilities may make the scan more capable but will also add to the scan time if it has to switch modes. There’s no free lunch. There’s always a tradeoff between scan quality and time.
AI is great at *certain* narrow medical image interpretation tasks. But there isn’t a massive training set of data for this “new” modality. I wouldn’t expect AI to be very good at reading these scans until they’ve accumulated millions. That means they are still paying human radiologists to interpret for the foreseeable future.
Everything in medicine is based on evidence. Proving that lung cancer screening saves lives took a decade. Where are the studies for this? So far just hype. More concretely, without evidence insurance won’t pay.
Finally, Who is this technique for? Yes it avoids ionizing radiation but so does MRI. Yes it’s quick, but so is a CT scan. The scan may be quick but the interpretation may be slow (It’s still dependent on human radiologists) and the machine may require time to clean. It can’t image lots of body parts so it’s hard to see how it replaces “whole body MRI scanners.” I’m sure there are tech/wellness bros who are excited but pay out of pocket for low quality wuick partial body scans but wider adoption depends on more than hype.
Novo Nordisk hackers got in through a GitHub token left in a repo
stayed for two months
took 1.3TB of data including unreleased drug formulas and internal AI models
then asked for $25 million
Novo Nordisk said no
so now they're selling Ozempic's secrets on the dark web
a GitHub token did this
@Andercot@bscholl Sigh.
Whatever happened to the good old crackpot ideas like capturing hurricanes with hundreds of thousands of gigascale wind turbines? Or lassoing asteroids into orbit to convert their relative motion into kinetic energy parcels which smash together to generate heat?

Риелтор из Японии не разобралась, как убрать её напарника в хромакее из видео, и выставила его как есть. В результате ролик набрал 810 000 просмотров за сутки, хотя предыдущие видео собирали максимум несколько тысяч.
This is the coolest thing ever. We’re at NASA getting a tour from astronaut Anne McClain. This is us entering the Orion capsule that flew around the Moon in April.
Set II is ready @ElonMusk
"First rule in government spending: Why build something once when you can build it twice for 3x the cost???"
We built Set I in a studio near downtown Austin but the space was only available for a week so we had to tear it down last Friday.
Like SpaceX, it would be completely unreasonable to expect the first rocket to make it to orbit so on Wednesday I rented an aircraft hanger 15 minutes from Giga Texas and we started construction on Set II.
We finished it on Saturday night and can now record anytime in the next 30 days.
The most entertaining outcome is the most likely.
Let's make this happen. 🏴☠️
It is humbling to consider that if we harness just 1 millionth of the Sun’s power for AI, that will be much more than a million times the intelligence of all of humanity
@2col6@ehak1@CupoJoeBlow@ryankatzrosene Depends on how you count em. First one was 2002, and we’ve had half a dozen big ones and another half dozen minor ones since that.
Speak for yourself. I want Mars fully terraformed. I want grad schools and government research on the Moon and in solar orbit. I want bigger data centers, better AI. I have a robot chauffeur and maid. Butler next.
I want all of these things and many others not yet mentioned.
Nobody wants a city on Mars. Nobody wants AI in every app. Nobody wants a robot butler. Nobody wants data centers everywhere. Nobody wants flying cars or humanoid robots. We want clean water, we want bees to survive, and we want a habitable planet.
Liberals are saying Trump’s Iranian Peace Deal is a thousand times worse than Obama’s deal.
Do the math. The 300 billion Trump is giving them is only 175 times more than the 1.7 billion Obama gave them. Adjusted for inflation, that makes this deal only 100 times worse.
Liberals love to exaggerate.
