GMU students make 3D printed prosthetic arm for violinist | khou.com – KHOU

Students from George Mason University design prosthetic arm for violist

Peggy Fox, WUSA 9:46 PM. CDT April 20, 2017

FAIRFAX, VA (WUSA9) - A new beginning for a Fairfax County girl who has just received a new prosthetic arm that was designed and 3-D printed by George Mason University college students.

Isabella Nicola, 10, has been raised by her mother, Andrea Cabrera, to never say never.

"My mom's phrase is, when you say 'I can't do it', it's 'I can't do it yet,'" said Nicola.

The fifth grader signed up to play violin in the strings program at Island Creek Elementary in Franconia last year, even though she knew it'd be a little difficult.

She was born with an incomplete left arm. Her music teacher fashioned a makeshift prosthetic arm out of PVC to hold her bow. Then he a called his alma mater and got the engineering department on board.

But now, Isabella has a bright pink, custom-made, brand new prosthetic arm that allows her to hold and move the bow properly.

"I have to say thank you to them because without them I couldn't really be able to play," said Nicola.

The five students have been working as a team for more than a year on their capstone senior project. It was designed, 3D printed, and pieced together by five George Mason University bioengineering students, Yasser Alhindi, the lead, Abdul Gouda, Mona Elkholy, Ella Novoselsky and Racha Salha.

Dr. Elizabeth Adams, a GMU music teacher, explained that a player's arm movement affects the violin's sound. Adams worked with the students and Isabella, providing advice.

The faculty mentors are Wilsaan Joiner and Vasiliki Ikonomidou. Laurence Bray is head of the bioengineering department.

"We were brainstorming ideas right away. We were aiming to take the strain off her shoulder to make her as comfortable as possible," said Ella Novoselsky.

"It's amazing. They didn't have any background when they started, of the mechanical engineering aspect. I'm amazed. When they came to me with all those designs, and they told me, this is going to go there and this will go like that. 'Ok, sure,'" saidVasiliki Ikonomidou, one of the mentors said about the student designers.

For Thursday's hand-off, the students had a surprise for Isabella. They also made a grip so that she can ride bike with both arms. Isabella beamed as she held it like she was holding the handlebars.

"Very cool and nice...They thought about other things. They went above and beyond," said Isabella.

She and the college students hit if off from the start. At their first meeting, Racha Salha said Isabella was "making jokes and laughing. We were actually the ones who were nervous....She's amazing."

"I want her to play the violin and love playing the violin and be excited. And I want her to believe she can do anything she wants," said Ella Novoselsky.

The bioengineering department has already received more inquiries from other people, so another group of students could soon have a new project on their hands.

First trimester brain ventricle fluid and embryonic volumes measured by three-dimensional ultrasound with the use of I-Space virtual reality

STUDY QUESTION

Is it possible to evaluate first trimester brain ventricle development in human pregnancies using an innovative virtual reality (VR) application and to analyze the relation of the embryonic volume (EV) and brain ventricle fluid volume (BVFV) with gestational age (GA), crown-rump length (CRL) and the Carnegie stage?

SUMMARY ANSWER

Volumetry and staging of the human embryo using a VR application make it possible to obtain unique information about in-vivo embryonic normal and abnormal development and about the sizes of the ventricles and body.

WHAT IS KNOWN ALREADY

Human brain development is complex and has a rapidly changing anatomy during the first trimester of pregnancy. New insights will enable early detection of cerebral pathology.

STUDY DESIGN, SIZE, DURATION

In a prospective cohort study, we weekly performed three-dimensional (3D) ultrasound examinations in 112 uncomplicated pregnancies between 6 + 0 and 12 + 6 weeks GA.

MATERIALS, SETTING, METHODS

The examinations resulted in 696 3D ultrasound scans that were transferred to the I-Space VR system and analyzed using V-Scope volume rendering software. V-Scope is used to create a ‘hologram’ of the ultrasound image and allows depth perception and interaction with the rendered objects. The CRL measurements were performed with a tracing tool, and the volume measurements were automatically performed with a segmentation algorithm. The embryos were staged according to the internal and external characteristics of the Carnegie staging system. All longitudinal outcomes were analyzed using repeated measures ANOVA.

MAIN RESULTS AND THE ROLE OF CHANCE

CRL could be measured in 91% of the datasets and ranged from 2.5 to 79.0 mm. EV could be measured in 66% of the datasets and ranged from 2.4 to 23 812.0 mm³, whereas the BVFV could be measured in 38% of the datasets and ranged from 10.4 to 226.3 mm³. Finally, in 74% of the datasets, the embryos were staged according to the Carnegie criteria, starting as early as stage 12. Reference charts of volumes versus GA, CRL and stage were constructed. There was no significant relationship between the CRL or EV and the birthweight.

LIMITATIONS, REASONS FOR CAUTIONS

The low success rate is a limitation of this study that can be explained mainly by non-targeted scanning of the embryonic head.

WIDER IMPLICATIONS OF THE FINDINGS

The I-Space VR system and the V-Scope software enable automatic EV and BVFV measurements and 3D observations of embryonic development in the first trimester. This allows in-vivo staging of human embryos based on both internal and external morphological characteristics.

STUDY FUNDING, COMPETING INTERESTS

None.

How 3D Printers Are Reshaping Medicine

Printing off a kidney or another human organ may sound like something out of a science fiction novel, but with the advancements in 3D printing technology, the idea may not be so far-fetched.

BioprintingWhile 3D printing has been successfully used in the health care sector to make prosthetic limbs, custom hearing aids and dental fixtures, the technology is now being used to create more complex structures - particularly human tissue.

Organovo (onvo), a San Diego-based company that focuses on regenerative medicine, is one company using 3D printers, called bioprinters, to print functional human tissue for medical research and regenerative therapies.

"This is disruptive technology," said Mike Renard, Organovo's vice president of commercial operations. "It's always interesting and fun, but never easy."

(More From CNBC: 15 Surprising Global Technology Cities)

Traditional 3D printing, also known as additive manufacturing, is a process of making three dimensional solid objects from a digital model. 3D printing is achieved using additive processes, in which an object is created by laying down successive layers of material such as plastic, ceramics, glass or metal to print an object. Companies including Boeing (ba), General Electric (ge) and Honeywell (hon) use this type of 3D printing to manufacture parts.

Bioprinters, though, use a "bio-ink" made of living cell mixtures to form human tissue. Basically, the bio-ink is used to build a 3D structure of cells, layer by layer, to form tissue.

Eventually, medical researchers hope to be able to use the printed tissue to make organs for organ replacement.

However, growing functional organs is still at least 10 years away, said Shaochen Chen, a professor of nano-engineering at the University of California, San Diego, who uses bioprinting in researching regenerative medicine.

But even though developing functional organs may still be a decade off, medical researchers and others are using bioprinting technology to make advancements in other ways.

After a year like this one, venturing into the recesses of the mind with the help of an entheogen could be one way to bring some clarity to 2020so long as youve put some planning and intention into your experience and youve prepared a safe and comfortable setting. Many of the gifts on this list are also complementary to meditation, yoga, and other wellness or spiritual practices.

While safety is priority number one when taking a mind-altering substance, enhancing the sensory effects of a psychedelic journey comes in at a close second. When the trip is over, integration is also key. This list was built with these things in mind.

A private online sound bath with Dynasty Electrik

Dynasty Electrik is Jenny Electrik (vocals, theremin, singing bowls) and Seth Misterka (production, ... [+] DJ, sax, guitar, vocals, singing bowls, gong).

Any experienced psychonaut knows the synesthesia that comes with a psychedelic experience begs for some sort of sound, whether its your favourite Tame Impala record or the sounds of nature. Now imagine floating along the vibrational waves of a private sound bath complete with gongs, singing bowls, flute, vocals, electronic tones, and more while your turned on, tuned in, and dropping out.

The Immortality Key by Brian C. Muraresku, foreword by Graham Hancock

The Immortality Key by Brian C. Muraresku explores the role psychedelics have played in the origins ... [+] of Western Civilization.

Some theologians have said there is reason to believe Moses was tripping on a hallucinogen when he saw the burning bush. This is just one of several instances in the bible believed by some to be associated with psychedelic plant medicines. While there has been much speculation on the role psychedelics may have played in early Christianity and the origins of Western civilization, Brian C. Muraresku seeks to bring some clarity to the conversation in his debut book. In The Immortality Key: The Secret History of The Religion With No Name, Muraresku puts 10 years of research to paper, offering readers a deep dive into the connections between Ancient Greece, Christianity, and the ancient use of visionary drugs. Using scientific research, classical literature, biblical scholarship and art, Muraresku offers the real story behind Jesus and the biggest religion in the world.

Glow CBD Bath Bomb by Kush Queen

Kush Queen's Glow CBD bath bomb is a great enhancement to your post-trip soak.

After a psychedelic trip, taking time to reflect and integrate is important. Olivia Alexander is the founder of cannabis brand Kush Queen, and is an advocate for cannabis and psychedelics for health and wellness. She began her line of bath bombs for people to experience cannabis in a more approachable way. After an experience with psilocybin, one of her favourite ways to ponder it is with a bath. When I trip, I think having a bath the next morning can really take the experience deeper, like putting a period on the end of the sentence of a trip by bringing you more into your body, she says. The Glow bath bomb features 200 milligrams of hemp-derived CBD, a combination of essential oils, and a special non-toxic ingredient, mica, to make it glow in the dark. A little charge under a light before your soak and this handmade bath bomb will bring some groovy vibes to the tub. Use a black light for a more intense glow.

Chocolate molds

Psilocybin-infused chocolates make ingestion of magic mushrooms much, much more pleasant.

While some might be content to chew magic mushrooms whole, eating what tastes like a mouthful of dirt might not be the most ideal method of ingestion for some. Its easy enough to toss a couple of stems and caps onto a pizza, but the shared history of mushrooms and chocolate (well, cacao) makes them a great combinationand one thats much more delicious than eating the dried fungus on its own. The Aztecs sometimes combined cacao, the food of the gods, and mushrooms, the flesh of the gods, in a beverage to be consumed in religious ceremonies as the two ingredients are thought to have a synergistic effect. Making mushroom-infused chocolates is one way to capitalize on this connection. Combined with this DoubleBlind recipe for infused chocolates, a fun set of chocolate molds make a great stocking stuffer for the DIY-type on your list. Try Etsy for mushroom-shaped molds and Amazon for, well, anything else.

Pressed on 180-gram colored vinyl, all titles but one were cut from the original analog tapes. According to VMP, the quality is so good, it sounds like the Dead is playing in your living room.

A subscription to Synctuition, a meditation app that uses 3D sound

The Synctuition app stands out from the crowd of existing mindfulness tools for its rich layers of ... [+] sound, personalization, and friendly user interface.

Meditation apps are nothing new, but for the psychonauts out there, one stands out from the crowd of existing tools for its rich layers of sound, personalization, and friendly user interface. Developed over the course of 10 years, Synctuition combines 3D sound, binaural beats, rhythmic sounds, and your own personalized frequency (determined with a voice recording when you set up the app) to provide a series of 25-minute soundscapes for meditation that promote better sleep, relaxation, clarity, lower stress, and reduced anxiety.

New NFT/Bitcoin Handheld Will Likely Cost $500 – Kotaku

Ordz Games has revealed a new retro-inspired handheld gaming console that will allegedly let players earn Bitcoins while playing games that are connected to the larger blockchain network. The console isnt out yet, but will likely cost around $500, according to the company behind the device.

I Hate This FF7 Rebirth Characters Whole Vibe

Sure, in 2024 the new hot thing among most large tech companies and Silicon Valley investors is AI. But there are still some folks out there dedicated to NFTs, cryptocurrency, and the blockchain. Despite the rollercoaster stability of all this crapBitcoin prices dropped $5,000 last weekthere still seems to be a market for this stuff. So, say hello to the BitBoy One.

Revealed on April 5, the BitBoy One is an upcoming handheld gaming console that is designed to also be a crypto wallet. It will also be able to play classic gamesassuming you provide the romsand will let you earn Bitcoin cryptocurrency by playing specific blockchain play-to-earn games. If the device looks very familiar, thats because it seems to be heavily based on similar retro devices like the Miyoo Mini and Anbernic RG35XX. In fact, the BitBoy One shares a lot of the same internal specs as those popular mini-retro handhelds. However, those devices cost between $60 to $100. Meanwhile, Ordz Games tells GamesBeat that the BitBoy One will likely cost around $500.

This device is very deeply rooted inside of Bitcoin, said the person behind the device, entrepreneur z3th. So the whole design language, the naming, is Bitcoin. Its all going to come with a 3D rendering of the physical device, which will be in an ordinal.

Whats an ordinal? Well, heres how GamesBeat describes them:

Ordinals are a way to create Bitcoin NFTs by attaching data such as images, videos, and more to an individual satoshi (the smallest form of Bitcoin currency) on the base Bitcoin blockchain.

Apparently, these Bitcoin/NFT hybrids have been around since January 2023 and will be a key part of the BitBoy One. The creator also claims youll be able to mine Bitcoin using the device, but admits that the weak, tiny BitBoy One wont be able to actually earn much.

The mining power of the physical device is very, very weak. It will take years to mine, said z3th. Youre not going to make real money from it. But its for fun.

If a lot of this sounds a bit wishy-washy and not really specific, thats becauseas with most blockchain products and plansits all very vague. Z3th is making lots of promises about earning money and Bitcoins and ordinals using the device. They say it will also mine coins and be a wallet for you. And there will be multiplayer support and the ability to play old games against friends to earn cryptocurrency, too. But nothing concrete on when to expect the BitBoy One, the actual price, or why most people would pay $500 for this device when similar retro handhelds can be bought for less than $100.

Perhaps Ill be proven wrong and this device will be incredible and make me a believer in NFTs and crypto. But uh, I wont be pre-ordering it anytime soon.
