Compelling new research led by scientists from the University of Pennsylvania has used a novel machine learning method to analyze hundreds of brain scans from patients with schizophrenia. The results reveal significant differences in gray matter volume… Continue reading Brain scan study discovers a new type of schizophrenia
The medical device giant has issued fixes for bugs first disclosed in 2018 and 2019. Continue reading Medtronic Patches Implanted Device, CareLink Programmer Bugs
Magnetic resonance imaging (MRI) is a great tool for diagnosing disease in different organs and tissues, but it can be costly and cumbersome. Now, engineers at the Boston University Photonics Center have developed a new device, small enough f… Continue reading Magnetic metamaterial amplifies MRI for clearer images in less time
I was the final volunteer in the world’s first brain imaging study on salvia divinorum. Continue reading What It’s Like to Smoke Salvia for Science
Hackers love to make music with things that aren’t normally considered musical instruments. We’ve all seen floppy drive orchestras, and the musical abilities of a Tesla coil can be ear-shatteringly impressive. Those are all just for fun, though. It would be nice if there were practical applications for making music from normally non-musical devices.
Thanks to a group of engineers at Case Western Reserve University in Cleveland, there is now: a magnetic resonance imaging machine that plays soothing music. And we don’t mean music piped into the MRI suite to distract patients from the notoriously noisy exam. The music is …read more

Why in the world does helium kill iPhones and other members of the Apple ecosystem? Enquiring minds want to know, and [Ben Krasnow] has obliged with an investigation of the culprit: the MEMS oscillator. (YouTube, embedded below.)
When we first heard about this, courtesy in part via a Hackaday post on MRI-killed iPhones, we couldn’t imagine how poisoning a micro-electromechanical system (MEMS) part could kill a phone. We’d always associated MEMS with accelerometers and gyros, important sensors in the smartphone suite, but hardly essential. It turns out there’s another MEMS component in many Apple products: an SiT 1532 oscillator, a …read more

Apple devices haunted by helium. Continue reading Spooky miasmic gas bricks hospital iPhones (mwah ha ha ha)
The bizarre incident happened during the installation of an MRI machine and was a surprise to everyone except Apple. Continue reading Why a Helium Leak Disabled Every iPhone in a Medical Facility
The brain is quicker to judge something as negative, because it’s easier than reframing to positive thinking. Continue reading Neuroscientists Find That It’s Easier to Be a Pessimist
We live in a world where anyone can build a CT machine. Yes, anyone. It’s made of laser-cut plywood and it looks like a Stargate. Anyone can build an MRI machine. Of course, these machines aren’t really good enough for medical diagnosis, or good enough to image anything that’s alive for that matter. This project for the Hackaday Prize is something else, though. It’s biomedical imaging put into a package that is just good enough to image your lungs while they’re still in your body.
The idea behind Spectra is to attach two electrodes to the body (a chest cavity, …read more
