A 3D-printed soft robotic hand that can play Nintendo

Posted by in categories: 3D printing, biotech/medical, cyborgs, robotics/AI

A team of researchers from the University of Maryland has 3D printed a soft robotic hand that is agile enough to play Nintendo’s Super Mario Bros. — and win!

The feat, highlighted on the front cover of the latest issue of Science Advances, demonstrates a promising innovation in the field of soft robotics, which centers on creating new types of flexible, that are powered using water or air rather than electricity. The inherent safety and adaptability of soft robots has sparked interest in their use for applications like prosthetics and biomedical devices. Unfortunately, controlling the fluids that make these soft robots bend and move has been especially difficult—until now.

The key breakthrough by the team, led by University of Maryland assistant professor of mechanical engineering Ryan D. Sochol, was the ability to 3D print fully assembled soft robots with integrated fluidic circuits in a single step.

I’m 11, I have a physics degree and want to make humans immortal

Posted by in categories: 3D printing, existential risks, finance, food, government, law enforcement, nanotechnology, quantum physics, robotics/AI, transhumanism

As someone with a passionate interest in longevity, transhumanism and biological immortality — I am naturally both excited and optimistic that medical technology will continue to advance in my lifetime — hopefully to the point where humanity has cured or at least greatly mitigated the signs & symptoms of most diseases as well as disabilities, radically expanded human biological lifespan regardless of age, and created a more dignified existence for all as a result of rapid breakthroughs in robotics, AI, automation, nanotechnology, 3D printing and biotechnology — which I hope in turn will largely eradicate poverty, disease, food & shelter insecurity, natural resource scarcity, environmental degradation and income inequality. I know that some of my likeminded friends are far more skeptical that we will ever see outright cures or significant mitigations for major diseases and disabilities — much less radical life extension or perhaps biological immortality in human beings — which are widely available on a commercial basis. They cite their belief that pharmaceutical giants, a plethora of not for profit organizations (i.e., American Cancer Society), and many other allegedly “self-interested parties” supposedly allied with government regulatory bodies — apparently do not want to see diseases or disabilities cured or lifespan significantly extended — EVER — as this would prevent them from earning untold sums selling treatments and supports for such things on a regular ongoing basis (i.e., chemo drugs for cancer, statins for cardiovascular disease, inhaled/oral steroids for lung disease, renal replacement therapy for kidney disease, mobile supports for spinal cord injuries, ect.) They believe that too much money would be at stake, too many jobs on the line and the entire “pharma-medical-academic industrial complex” supposedly at great risk, if actual cures or significant mitigations ever saw the light of day. Some of these friends even cite their belief that fully autonomous, accident proof, self-driving cars will most likely never occur — as it would supposed put the entire auto insurance industry at existential risk as well as deprive law enforcement agencies of a key source of reliable revenue (issuing speeding tickets) This one makes me giggle! 🤭 My friends also believe that radical life extension in human beings — much less biological immortality — would apparently upset the proverbial apple cart — where the “powers that be” are concerned — in terms of everything from the highly lucrative profits which are derived from pharmaceutical sales, old age homes, life and health insurance plans, personal financial services and all of the sales of key products and services associated with the aging process — to macroeconomic considerations such as the long term viability of government entitlement programmes. They believe that government regulatory authorities allegedly working at the behest of the aforementioned self-interested parties will always seek to delay, disrupt or even derail ANY and ALL significant progress into cures/mitigations for disease/disabilities, radical human life extension and/or human biological immortality. Apparently, new biotech start ups which do advance the aforementioned things are allegedly “always aggressively bought out by monopoly capital — with their cures and advances indefinitely suppressed” I personally tend to be more on the positive and optimistic side where these things are concerned — but perhaps these rather pessimistic arguments do have some validity — minus the implied conspiracy theory aspect. Do you think human beings will ever be “allowed” to truly be free from illnesses and disabilities? Will we ever be “permitted” to radically expand our lifespans or even become biologically immortal at some point? Please discuss.


I have already taken a few courses for a master’s in physics at the University of Antwerp and I want to complete it there. In a bachelor’s degree you get a basis of knowledge in physics and quantum physics, but it gets more detailed in a master’s.

The main reason I chose to study physics is because my end goal is to achieve immortality. One of the areas that is important in the study of immortality is physics, but as of yet, there is no mapped out path to achieve it.

NASA inches closer to printing artificial organs in space

Posted by in categories: 3D printing, bioengineering, biotech/medical, life extension

In America, at least 17 people a day die waiting for an organ transplant. But instead of waiting for a donor to die, what if we could someday grow our own organs?

Last week, six years after NASA announced its Vascular Tissue Challenge, a competition designed to accelerate research that could someday lead to artificial organs, the agency named two winning teams. The challenge required teams to create thick, vascularized human organ tissue that could survive for 30 days.

The two teams, named Winston and WFIRM, both from the Wake Forest Institute for Regenerative Medicine, used different 3D-printing techniques to create lab-grown liver tissue that would satisfy all of NASA’s requirements and maintain their function.

3D bioprinted heart provides new tool for surgeons

Posted by in categories: 3D printing, bioprinting, biotech/medical, engineering

Circa 2020


The FRESH technique of 3D bioprinting was invented in Feinberg’s lab to fill an unfilled demand for 3D printed soft polymers, which lack the rigidity to stand unsupported as in a normal print. FRESH 3D printing uses a needle to inject bioink into a bath of soft hydrogel, which supports the object as it prints. Once finished, a simple application of heat causes the hydrogel to melt away, leaving only the 3D bioprinted object.

Scientists 3D-print human liver tissue in a lab, win top prizes in NASA challenge

Posted by in categories: 3D printing, biotech/medical

Scientists have successfully grown liver tissue capable of functioning for 30 days in the lab as part of NASA’s Vascular Tissue Challenge.

In 2016, NASA put forth this competition to find teams that could “create thick, vascularized human organ tissue in an in-vitro environment to advance research and benefit medicine on long-duration missions and on Earth,” according to an agency challenge description. Today (June 9), the agency announced not one, but two winners of the challenge.

How Going to Mars Could Save Earth

Posted by in categories: 3D printing, nuclear energy, space travel

Article I just wrote about how going to Mars is actually good for protecting life on Earth, too.


People often lump going to Mars or the Moon into a this/that fight when it comes to bettering the life of the Earth and its inhabitants. But, it’s not that simple.

The technology we master in the pursuit of space colonization (starti n g at the Moon and Mars / space stations) will serve to advance that on Earth. The things we learn will help provide a guide for what to do on this future planet, and not just life beyond it. Sure, in-situ resource utilization/production will generate rocket fuel on extraterrestrial bodies. But, things like the NASA Kilopower nuclear reactor can lay the groundwork for alternative energies deployed on Earth at scale. I imagine thorium reactors will follow suit while we still try to deploy fusion at a consumer scale and not just a research basis.

What’s the Deal with 3D Printed Food?

Posted by in categories: 3D printing, food

3D printed food is no longer the domain of sci-fi fantasy. It’s here and it’s real: but is it really a big deal, or is it just a passing fad?


In science fiction television shows and movies such as those in the Star Trek universe, the food synthesizers or replicators were electronic devices that took base elements and transformed them into any type of food that was desired. This seemingly miraculous device could only exist in the world of science fiction — at least for now. However, thanks to the advances in 3D printing, it is now possible to create food that mimics the taste, shape, and color of familiar dishes.

Over the past few years, 3D printers have become more commonplace in commercial industries and are used to create all types of items that range from small models and jewelry up to large construction items used to create buildings. But what about 3D printed foods? Is it the future of gastronomy, or just a quirky fad?

3D printing stem cells to transform neuroscience

Posted by in categories: 3D printing, biotech/medical, health, neuroscience, robotics/AI

3D printing, also called additive manufacturing, has become widespread in recent years. By building successive layers of raw material such as metals, plastics, and ceramics, it has the key advantage of being able to produce very complex shapes or geometries that would be nearly impossible to construct through more traditional methods such as carving, grinding, or molding.

The technology offers huge potential in the health care sector. For example, doctors can use it to make products to match a patient’s anatomy: a radiologist could create an exact replica of a patient’s spine to help plan surgery; a dentist could scan a patient’s broken tooth to make a perfectly fitting crown reproduction. But what if we took a step further and apply 3D printing techniques to neuroscience?

Stems cells are essentially the body’s raw materials; they are pluripotent elements from which all other cells with specialized functions are generated. The development of methods to isolate and generate human stem cells, has excited many with the promise of improved human cell function understanding, ultimately utilizing them for regeneration in disease and trauma. However, the traditional two-dimensional growth of derived neurones–using flat petri dishes–presents itself as a major confounding factor as it does not adequately mimic in vivo three-dimensional interactions, nor the myriad developmental cues present in real living organisms.
