The MucoJet, for Needle-Free, Painless Vaccinations…

Injections for vaccinations, while saving the lives of millions of people from common sicknesses and diseases, are still pretty painful; particularly for younger children who are most at risk of diseases. That might change within the next ten years, thanks to researchers in Dorian Liepmann’s lab at the University of California, Berkeley, who’ve developed the MucoJet. The creation is a needle-free, pill-sized, 3D-printed device that shoots a stream of vaccine into the tissue of the cheek, making vaccinations practically painless.

About two-and-a-half years ago, The PractitioNERD released a blog post about some free architecture courses offered by MIT, TU Delft, edX and the Open Online Academy. Basically, if you want to continue learning about the world of architecture without forking over the dough for a  master’s or a doctorate, this is a good way to go.  Essentially, taking short-term courses remotely have become popular worldwide as educational alternatives as they make it easier to dive into the varied topics these coursed cover, thanks to platforms like edX (offered by Harvard and MIT).  Continue reading Here’s MORE Free Online Architecture Courses from World-Class Universitites!

The Early Years of the Computer Mouse – Doc’D #42

In this technology-themed episode of PractitioNERD Documented, or “Doc’D”, host Montez McCrary will be discussing the early history of the computer mouse. Continue reading The Early Years of the Computer Mouse – Doc’D #42

Researchers Develop Paper Clip-Mized Mind Control Device Installed in your Brain…

Yes, you heard correct! This is the stentrode, described as a “bionic spinal cord”, and it records brain activity and converts those signals into electrical commands to control bionic limbs — according to results from clinical trials.  Doctors say it could also let a person pull a Professor Charles Xavier and move a wheelchair using only their thoughts.

Doctors Will Start Using 3D-Modeling Before Your Next Sinus Surgery

This story intrigues me as someone who has had allergies and sinus issues every year since the age of two, and surgury is something I’m strongly considering. Now, the sinus’ close proximity to the eyes and brain (including its super-sensitive nature) means that the single slip of the surgical scalpel can result in negative and permanent repercussions. Because of this, researchers at the Ohio State University’s Wexner Medical Center have developed a 3D-modelling technique that maps out the sinus cavity of each patient before their surgery, giving doctors the opportunity to practice the upcoming procedure and see exactly what effect (if any exist) the surgery could have on the patient. Continue reading Doctors Will Start Using 3D-Modeling Before Your Next Sinus Surgery

Behold this Mind-controlled Robot That Gives the Disabled a Taste of Travel

Wow you guys; we already have brain-controlled robot limbs assisting the disabled regain some mobility, but what about a free-roaming operating FULL-FLEDGED robots controlled by our thoughts?!? Seems far-fetched and elusive, right?  WRONG! Swiss researchers have developed a mind-controlled telepresence robot that allows anyone with motor disabilities to travel when it would otherwise prove to be impractical.  Continue reading Behold this Mind-controlled Robot That Gives the Disabled a Taste of Travel

ASU Scientists Created a White Laser that Could Potentially Light-up our Homes!

“Lasers” have been advancing the world of science and threatening good-guy movie characters ever since the 1960s, but we’re used to seeing them with a certain distinct color (SPOILERS; it’s red). However, it seems that a team of research scientists from Arizona State University have developed the world’s first white semiconductor laser that can emit light across the entire visible spectrum and provide the full range of different colors that are required to make white laser light.

I can only assume as someone who doesn’t have to perform this task often (practically NEVER), but I’m almost certain that pricking your finger for a blood glucose test will never, ever be a fun thing to do. And because science is a thing, scientists (that’s Latin for “people who science’) have been working on a bloodless and needleless alternative. Essentially, it’s a rub-on temporary tattoo that gently sucks glucose through the surface of the skin like a vampire. An inked-up, sci-fi, gadgety vampire… Continue reading A Rub-On Tattoo for Diabetics Could Mean the End of Finger Pricking
