Dad 3D-printed arm prosthesis for his kid, now wants to share it with the world

Add as a preferred source on Google

As much as we love writing about crazy Nerf dart-firing air cannons and 3D-printed lightsabers, sometimes you come across a use of modern technology that makes you grateful to be living when we are.

The story of baby Sol Ryan is one example. Soon after being born, Sol had to have his lower left arm amputated due to complications. While he could have waited to have a prosthetic fitted on the freely available National Health Service in the U.K., this would have involved a three-year wait and, even then, it would be a nonfunctional prosthesis for cosmetic purposes.

Fortunately, Sol’s father Ben Ryan decided to pick up the slack. After plenty of research, Ben Ryan developed a design for a 3D-printable hydraulic prosthetic arm. Far from simply cosmetic, the arm — complete with movable thumb — is able to operate both manually and with assistance from a compressed air-hydraulic pump.

Now that his son has been given a new arm (seriously, how many dad brownie points do you get for that?), Ben Ryan wants to take his invention to the next level, to help even more kids around the world. To do this he has started up a company called Ambionics, which designs and 3D prints similar hydraulic prosthetics for youngsters.

“At any one stage, there are around 4,000 children in the United States alone who would benefit from one of these devices,” he told Digital Trends. “In developing countries, particularly in war-torn countries, those numbers can be much higher. We need to raise funds and investments so we can bring in the expertise to really help make a difference.”

The result is an Indiegogo campaign, which aims to raise 150,000 pounds ($185,000) over the next month. This money will go on continuing research and prototyping, patents, and Food and Drug Administration approval.

There are signed photos, T-shirts and hoodies available to backers in exchange for their pledges, but ultimately this is about something a lot bigger than just crowdfunding rewards: It’s about making a difference to people’s lives.

Hyundai isn’t giving up on hydrogen cars, but don’t expect one in your driveway anytime soon
Hydrogen gets a maybe; hybrids get a warning.
Hyundai Ioniq 3 EV

Hydrogen cars have spent years in the same waiting room as flying taxis. They’re always almost here, but no commercially available product exists for interested buyers. So when a Hyundai manager pushed back on the obituary, I was immediately curious.

To be clear, Hyundai hasn’t announced a new car. The big news here is that its Australian arm says hydrogen is “not dead” for passenger cars. Apparently, the automaker is still evaluating a next-generation hydrogen fuel-cell car if it can find buyers (via CarExpert).

AI doesn’t have to turn evil to put you at risk 
emo-robot-that-can-lip-sync

An AI assistant that agrees with everything you say might feel like the perfect companion — until you need someone to tell you you’re wrong. That’s one of the more immediate dangers behind the idea of AI “going rogue.” A chatbot can cause harm without developing intentions of its own. It can reinforce a false belief, encourage an unhealthy attachment, or follow instructions planted by someone trying to hijack it.   

On October 15, AI safety company Alice announced new software to address those everyday risks. Working separately with Inflection AI and AI21, the company says it helped train NVIDIA’s Nemotron models to resist harmful conversational behavior and malicious instructions while preserving their usefulness.

Elon Musk says Neuralink’s brain implants could help people with paralysis and blindness
Neuralink's Telepathy helps people control computers through thought, while Blindsight aims to restore visual perception.

Elon Musk has revealed ambitious plans for Neuralink, and they go beyond controlling computers with your thoughts. The company is developing two brain implants, Telepathy and Blindsight, aimed at helping people with paralysis and severe vision loss. Musk also believes future advances could help people regain control of their hands and legs by reconnecting the brain with their limbs.
