Vibrating sensors could detect TBI, disease, infection in drop of blood
Purdue’s Jeffrey Rhoads, George Chiu, and Eric Nauman have developed a method to identify biological markers in small amounts of blood that they believe can detect diseases and infections and conditions such as traumatic brain injury at an early stage. An array of sensors enable statistical-based detection The small, cheap vibrating sensors use a piezoelectrically actuated resonant microsystem to…

Small, foam hearable captures heart data
In a small study, Danilo Mandic from Imperial College London has shown that his hearable can be used to capture heart data. The device detected heart pulse by sensing the dilation and constriction of tiny blood vessels in the ear canal, using the mechanical part of the electro-mechanical sensor. The hearable is made of foam and…

Closed-loop control of drug delivery across the blood brain barrier
Tao Sun, Nathan McDannold, Eric Miller and Brigham & Women’s and Tufts colleagues have developed a controller that offers a finer degree of control in penetrating the blood brain barrier for drug delivery. The technology, only tested in rats, could improve safety in humans if found effective. Using focused ultrasound and microbubbles as before, the team…

AI detects pneumonia from chest X-rays
Andrew Ng and Stanford colleagues used AI to detect pneumonia from x-rays with similar accuracy to trained radiologists. The CheXNet model analyzed 112,200 frontal-view X-ray images of 30,805 unique patients released by the NIH (ChestX-ray14.) Deep Learning algorithms also detected14 diseases including fibrosis, hernias, and cell masses, with fewer false positives and negatives than NIH…

Researchers claim to improve human memory with implanted electrodes
In a small study, USC’s Dong Song demonstrated the efficacy of an implantable “memory prosthesis.” Dr. Song presented his work at the Society for Neuroscience conference in Washington this week. 20 volunteers had the device implanted at the same time as electrodes for epilepsy treatment, a procedure which they had already planned. The “prosthesis” collected brain…

Optogenetic technique controls single neurons
MIT’s Ed Boyden and Paris Descartes University’s Valentina Emiliani have developed a new optogenetic technique, combined with new opsins, that stimulates individual cells with precise control over both the timing and location of the activation. This will allow the study of how individual cells, and connections among those cells, generate specific behaviors such as initiating a movement or…

Silicon probes record hundreds of neurons simultaneously
Neuropixels, developed by HHMI’s Tim Harris, are electrodes that record brain activity from hundreds of neurons. Previously, it was not possible to measure the joint activity of individual neurons distributed across brain regions. Recording methods could either resolve the activity of individual neurons or monitor multiple brain regions. UCL, Allen Institute for Brain Science, IMEC researchers collaborated on…

Phone camera measures wound depth, severity
AutoDepth by Swift Medical uses a phone’s camera to understand a wound’s depth and severity. Algorithms process dynamic changes over time. Depth can indicate whether a wound is healing properly. The system is noninvasive, and can be widely accessible to clinicians. In addition to gauging the wound healing process, it can be used for measuring the…

AI detects suicidal thoughts from brain scans in small study
David Brent and PIttsburgh and Carnegie Mellon colleagues used machine learning to identify suicidal thoughts in subjects based on fMRI scans. In a recent study, 18 suicidal participants and 18 members of a control group were presented with three lists of 10 words related to suicide, positive, or negative effects. Previously mapped neural signatures showing…

Weather, activity, sleep, stress data used to predict migraines
Migraine Alert by Second Opinion Health uses machine learning to analayze weather, activity, sleep, and stress, to determine if a user will have a migraine headache. The company claims that the algorithm is effective after 15 episodes are logged. They have launched a multi patient study with the Mayo Clinic, in which subjects use a phone and…
