Hackaday · High Frequency Food: Better Cutting With UltrasonicsYou’re cutting yourself a single slice of cake. You grab a butter knife out of the drawer, hack off a moist wedge, and munch away to your mouth’s delight. The next day, you’re cut…
Our communication on a new #ultrasound method for #bridgetesting won the prize for the best research #pressrelease of the year 2024 from @idw-online.de.
Congrats to our #pressoffice, including the author of the text, Moritz Müller: http://go.tum.de/388397

go.tum.deidw award for TUM: Best scientific press release of the yearThe press office of the Technical University of Munich (TUM) has received the award for the best research press release of the year 2024.
So I’ve been working on the tech behind the #Symbiophone over the last few weeks. I have a #DIY phase generator and now I’m preparing to test it in the #audible spectrum with regular #piezos while waiting for a delivery of an #ultrasound piezo.

My #MedicalInsurance just got switched from #UHC to #BlueShieldCA effective Jan 1, 2025.
Just got a medical bill from #UCSF for an #ultrasound for $425 out of $530 which was done in Dec 2024 when I was still covered by UHC.
This is the 1st supplemental #MedicalBill that I've ever received in the over 10 years that I was covered by UHC.
UHC previously fully covered all surgeries & other procedures, including another ultrasound, without any additional cost to me.
I can afford it. So that's not the issue.
But I just can't help but think that UHC deliberately understated the amount of coverage because they knew that my coverage with them was being terminated by my retirement board.
Can't prove it but that's what I think. 
Focused #ultrasound decreases Nucleus #Accumbens activity :

FrontiersNon-invasive suppression of the human nucleus accumbens (NAc) with transcranial focused ultrasound (tFUS) modulates the reward network: a pilot studyBackgroundThe nucleus accumbens (NAc) is a key node of the brain reward circuit driving reward-related behavior. Dysregulation of NAc has been demonstrated to contribute to pathological markers of addiction in substance use disorder (SUD) making it a potential therapeutic target for brain stimulation. Transcranial focused ultrasound (tFUS) is an emerging non-invasive brain stimulation approach that can modulate deep brain regions with a high spatial resolution. However, there is currently no evidence showing how the brain activity of NAc and brain functional connectivity within the reward network neuromodulated by tFUS on the NAc.MethodsIn this pilot study, we carried out a single-blind, sham-controlled clinical trial using functional magnetic resonance imaging (fMRI) to investigate the underlying mechanism of tFUS neuromodulating the reward network through NAc in ten healthy adults. Specifically, the experiment consists of a 20-min concurrent tFUS/fMRI scan and two 24-min resting-state fMRI before and after the tFUS session.ResultsFirstly, our results demonstrated the feasibility and safety of 20-min tFUS on NAc. Additionally, our findings demonstrated that bilateral NAc was inhibited during tFUS on the left NAc compared to sham. Lastly, increased functional connectivity between the NAc and medial prefrontal cortex (mPFC) was observed after tFUS on the left NAc, but no changes for the sham group.ConclusionDelivering tFUS to the NAc can modulate brain activations and funct...
