Amputees’ hopes to experience the feeling of human touch using their prosthetics are becoming closer to reality. Now, new technology is allowing them to feel temperature—even in limbs that are no longer part of their bodies.
For the first time, a functional artificial limb has been fitted with fingertip sensors that allow an ordinary prosthetic hand to sense and respond to temperature just as a living hand does. The device provides a realistic sense of hot and cold in the missing “phantom” hand by delivering thermal information to nerve areas on the amputee’s residual limb that the brain believes are still connected to the missing hand. The MiniTouch, described in a study published Friday in Med, was created with affordable off-the-shelf electronics, requires no surgery and can be fitted to existing commercial prosthetic hands in a matter of hours.
Little time lapse of me catching up to my immuno class, and drafting a sociology response. I’ve been wildly unmotivated so I have soooo much to catch up on. Hopefully tomorrow is a more productive day.
one thing i was hoping to learn during my post-bac but never really got around to was spike sorting. in my neural engineering class, i'm finally learning how to do that!
although i don't plan on collecting neural data at this level, i do hope to collect LFPs as part of my research so learning this signal processing in general is going to be extremely helpful. so far, i've determined my threshold and plotted the threshold line within the data. the hard part is everything that comes next of template matching, principal component analysis (PCA), and all the like. after not really using MATLAB in yeeears, this has been an adventure but i'm surprised at how much i've been able to recall and proud of myself for having no shame in googling MATLAB functions lol. i know i can figure this out, i'm smart(ish).
this hw is due feb 7th (with possibility of an extension if other people in the class take a while) so time to get her done. ft my pupper knocked out on the floor
people who work/study in quantitative bio-adjacent fields, rise up. computational neuroscience where you get to see someone's thoughts in feelings in graph form??? so cool. biophysics where you can pass blood plasma through an electric field to determine whether a patient has cancer or not?? unbelievable. biomedical engineering where you can literally build a device to pump someone's heart and be the difference between their life and death??? oh my god. disease modelling, being able to predict AND prevent communities being affected by disease on a large scale through your analysis of data??? i love science
3D Bioprinting Takes Eye Tissue Engineering to New Heights at NIH
Scientists at the National Eye Institute (NEI), part of the National Institutes of Health, have made a significant advancement in the field of 3D bioprinting by successfully creating functional eye tissue using this innovative technique. The potential for this development to revolutionize the treatment of eye conditions and diseases is vast, and further research will undoubtedly continue to build upon these groundbreaking findings.
The research team used 3D bioprinting and patient stem cells to create eye tissue that will help researchers better understand blinding diseases. The team printed a combination of cells that make up the outer blood-retina barrier, a type of eye tissue that supports the retina’s photoreceptors. This technique could potentially provide an unlimited supply of patient-derived tissue for studying degenerative retinal diseases like age-related macular degeneration (AMD).
Hello, I am a university student that is part of a group looking to improve certain aspects of manual wheelchairs. We have created a survey for both manual and electric wheelchair users to learn about some of their likes and dislikes, wants and needs, and more about their experiences. Due to all the red tape around this project, I can only reveal so much but rest assured this survey is intended for educational purposes to better understand user experiences and to identify areas of improvement for manual and power-assisted wheelchairs. The survey is composed of 15 questions, many of them being multiple choice with a few short response questions. The estimated time of completion is 6-8 minutes. If you are a current or past wheelchair user and have a few minutes to spare, our team would greatly appreciate your input on your experience with a manual or electric wheelchair! Thank you in advance!

i'm still studying human physiology online and i just completed a practice quiz on the endocrine system. i scored 100 percent! i'm happy with it because i genuinely enjoyed learning the topics taught in this module and took the quiz without any extra revisions. i still have one graded paper left for the 'week one' modules. i'll go through the lecture notes sometime later today.
i still need to complete 'ct scan' in my biomedical imaging course. i just happen to enjoy physiology a bit more than all the technical nuances involved in imaging. i might start with ct scans after lunch today.
i was watching 'my neighbour totoro' last night and accidentally fell asleep because i was so tired. i'll have to watch it again. its really cute and enjoyable. i'm thoroughly enjoying my studio ghibli movie marathon experience. the picture i've used above is a still in 'from up on poppy hill'. its another ghibli film i watched recently and liked.
i finished reading 'ikigai' yesterday and i actually found some interesting quotes and passages. i am especially intrigued by the concept of 'wabi-sabi' and i want to learn more about it. i'm still reading plath's journals. i have to finish my shakespeare collection before i'm off to uni.
there's a lot of packing left so i'll have to get to all of that soon. fun fact, i started working on my notion and i've customized it all to my preferences. its pretty helpful to organize my notes and thoughts. i recommend using it for school, college, work or for personal uses.
Of course the first day of finals is also the first day of spring in Chicago. It took me so much to actually go into the library, but golden hour inside the stacks always hits.
its my birth month! hello august! my birthday is tomorrow and i’m .. probably just going to get ice cream to celebrate. not exactly what i want but a happy medium :)
i got copies of the 2 major textbooks in my lab so i can do some of my readings at home and its been beneficial for me. in the coming weeks, i’ll be presenting a paper in my lab for our lil journal club, finishing animal trainings, and starting to perform surgeries! ahhhh such a busy month. so exciteddd. i also might find my way to chicago again but that’s veryyy up in the air.
oh! and i just moved into my very first apartment that’s my ownnnn, i live on my oWN. ah. so much is happening. enjoy this photo of me reading about the cytology of neurons.
