Hyperpolarization also allows for cheaper MRI scanners. With hyperpolarization, you achieve polarization (needed for SNR) without the need of big magnets (=expensive). Even in rich…

Out of curiosity, investment = crypto? I can relate a tiny bit.

Great explanation. Indeed, the "rotation/tumbling" is nothing to worry about. One of our biggest challenges is relaxation. The moment we polarize, the clock ticks. Usually, the tim…

I'm finishing my PhD in hyperpolarization (hopefully) soon. In my opinion, hyperpolarization will significantly contribute to early-stage diagnosis. We're designing machines, proce…

As a scientist, I'm so glad that we're forced to publish all our primary/secondary data along with the publication itself. It's stored in a repository which is "locked" when the DO…

I don't see any problem here.

I think not. It keeps battery cycles low and is likely better than some other behavior. As far as I remember, batteries don't like to go way below 20% and don't like fast charging …

Or an SSD. Is easy and cheap these days.

It's not only a matter of aesthetics but bacteria etc. Your brush head collects a sh*tload of food waste (which you don't see with your eyes) and remains a bit wet after usage. Per…

The brushes have this sensor for a reason. Too much pressure may harm your gum. The article talks about a ultrasound brush, no pressure required.

Clearly, he possesses considerable expertise, but it's puzzling why such a skilled individual would falter towards the end, resulting in poor solder joints on the 2.54mm pin header…

I have this brush and would highly encourage you to swap the head when the brush asks you to do so, for the sake of your dental health.

We use Kanboard in our institute, but its UI/UX is among the worst I've experienced. It's reliable, but extremely unintuitive, causing people to avoid using it. However, it has pot…

It's kinda strange, I tried to sell my Flipper Zero and was wondering why people name them weirdly. As it turns out, ebay doesn't allow to sell it. If anyone has an idea where I ca…

in case the author is reading this: I would suggest to add an affiliate tag to the Amazon link. I once heard that authors make more from the affiliate program than from the book it…

trolling or are there actual documentaries? Maybe depends on definition of "uncontacted"?

A friend wanted to register at facebook and his last name is "couple" in our language. Facebook shows an error claiming, that couples are not allowed to share an account - they sho…

I think in the legend, 2021 should be 2027 and 2017 should be 2021. Otherwise I doesn't make sense to me. Maybe someone wrote by accident 2017 instead of 2027 and then swapped the …

It fascinates me, that volume and automation can make this profitable. Very nice article and I would love to see a cost breakdown of a PCB manufacturer. There is still labour invol…

"A Brief History of Children Sent Through the Mail" As a german, I like the use of the word "Brief" (=letter) here.
