Lifting a glass, making a fist, entering a phone number using the index finger: it is amazing the things cutting-edge robotic hands can already do thanks to biomedical technology. However, things that work in the laboratory often encounter stumbling blocks when put to practice in daily life. The problem is the vast diversity of the intentions of each individual person, their surroundings and the things that can be found there, making a one size fits all solution all but impossible. A team at FAU is investigating how intelligent prostheses can be improved and made more reliable. The idea is that interactive artificial intelligence will help the prostheses to recognize human intent better, to register their surroundings and to continue to develop and improve over time. The project is to receive 4.5 million euros in funding from the EU, with FAU receiving 467,000 euros.
“We are literally working at the interface between humans and machines,” explains Prof. Dr. Claudio Castellini, professor of medical robotics at FAU. “The technology behind prosthetics for upper limbs has come on in leaps and bounds over the past decades.” Using surface electromyography, for example, skin electrodes at the remaining stump of the arm can detect the slightest muscle movements. These biosignals can be converted and transferred to the prosthetic limb as electrical impulses. “The wearer controls their artificial hand themselves using the stump. Methods taken from pattern recognition and interactive machine learning also allow people to teach their prosthetic their own individual needs when making a gesture or a movement.”
The advantages of AI over purely cosmetic prosthetics
At present, advanced robotic prosthetics have not yet reached optimal standards in terms of comfort, function and control, which is why many people with missing limbs still often prefer purely cosmetic prosthetics with no additional functions. The new EU Horizon project “AI-Powered Manipulation System for Advanced Robotic Service, Manufacturing and Prosthetics (IntelliMan)” therefore focuses on how these can interact with their environment even more effectively and for a specific purpose.
Researchers at FAU concentrate in particular on how to improve control of both real and virtual prosthetic upper limbs. The focus is on what is known as intent detection. Prof. Castellini and his team are continuing work on recording and analyzing human biosignals, and are designing innovative algorithms for machine learning aimed at detecting the individual movement patterns of individuals. User studies conducted on test persons both with and without physical disabilities are used to validate their results. Furthermore, FAU is also leading the area “Shared autonomy between humans and robots” in the EU project, aimed at checking the safety of the results.
At the interface between humans and machines
Prof. Castellini heads the “Assistive Intelligent Robotics” lab (AIROB) at FAU that focuses on controlling assistive robotics for the upper and lower limbs as well as functional electrostimulation. “We are exploiting the potential offered by intent detection to control assistive and rehabilitative robotics,” explains the researcher. “This covers wearable robots worn on the body such as prosthetics and exoskeletons, but also robot arms and simulations using virtual reality.” The professorship focuses particularly on biosignal processing of various sensor modalities and methods of machine learning for intent detection, in other words research directly at the interface between humans and machines.
In his previous research at the German Aerospace Center (DLR), where he was based until 2021, Castellini investigated the question of how virtual hand prosthetics could help amputees cope with phantom pain. Alongside Castellini, doctoral candidate Fabio Egle, a research associate at the professorship, is also actively involved in the IntelliMan project. The FAU share of the EU project will receive funding of 467,000 euros over a period of three and a half years, while the overall budget amounts to 6 million euros. The IntelliMan project is coordinated by the University of Bologna and the DLR, the Polytechnic University of Catalonia, the University of Genoa, Luigi Vanvitelli University in Campania and the Bavarian Research Alliance (BayFOR) are also involved.
The SupraBioNano Lab (SBNLab) at the Politecnico di Milano’s Department of Chemistry, Materials and Chemical Engineering “Giulio Natta”, in partnership with the University of Bologna and the Aalto University of Helsinki (Finland) has, for the first time, synthesised a superfluorinated gold nanocluster, made up of a core of only 25 gold atoms, to which 18 branch-structured fluorinated molecules are linked.
The metal clusters are an innovative class of very complex nanomaterial, characterised by ultra-small dimensions (<2nm) and peculiar chemical-physical properties such as luminescence and catalytic activity, which encourage its application in various scientific fields of high importance in relation to modern global challenges. These include precision medicine, in which metal nanoclusters are used as innovative probes for diagnostic and therapeutic applications, and the energy transition, where they are applied as efficient catalysers for the production of green hydrogen.
The crystallisation of metal nanoclusters offers the possibility of obtaining high-purity samples, allowing their fine atomic structure to be determined; however, at present this remains a very difficult process to control. The methodologies developed in this study promoted the crystallisation of nanoclusters, allowing their atomic structure to be determined. The end result is the structural description of the most complex fluorinated nano-object ever reported.
The atomic structure has been determined by means of x-ray diffraction at the Sincrotrone Elettra in Trieste. It will soon be possible to study the structure of these advanced nanomaterials at the Politecnico di Milano, where – thanks also to the grant from the Region of Lombardy – Next-GAME (Next-Generation Advanced Materials), a laboratory dedicated to the use of state-of-the-art x-ray instruments to characterise crystals, nanoparticles and colloids, is being established.
Among the authors of the study were Prof. Pierangelo Metrangolo, Prof. Giancarlo Terraneo, Prof. Valentina Dichiarante, Prof. Francesca Baldelli Bombelli, Dr. Claudia Pigliacelli (SBNLab); professor Giulio Cerullo, from the Politecnico di Milano’s Department of Physics, also contributed to the study, looking at the nanocluster’s optical characteristics and demonstrating the fluorinated binders’ impact on the gold core’s optical activity.

Slate.com is dedicating a month (January 2017) to Frankenstein. This means there were will be one or more essays each week on one aspect or another of Frankenstein and science. These essays are one of a series of initiatives jointly supported by Slate, Arizona State University, and an organization known as New America. It gets confusing since these essays are listed as part of two initiatives: Futurography and Future Tense.
The really odd part, as far as I’m concerned, is that there is no mention of Arizona State University’s (ASU) The Frankenstein Bicentennial Project (mentioned in my Oct. 26, 2016 posting). Perhaps they’re concerned that people will think ASU is advertising the project?
Getting back to the essays, a Jan. 3, 2017 article by Jacob Brogan explains, by means of a ‘Question and Answer’ format article, why the book and the monster maintain popular interest after two centuries (Note: We never do find out who or how many people are supplying the answers),
OK, fine. I get that this book is important, but why are we talking about it in a series about emerging technology?
Though people still tend to weaponize it as a simple anti-scientific screed, Frankenstein, which was first published in 1818, is much richer when we read it as a complex dialogue about our relationship to innovation—both our desire for it and our fear of the changes it brings. Mary Shelley was just a teenager when she began to compose Frankenstein, but she was already grappling with our complex relationship to new forces. Almost two centuries on, the book is just as propulsive and compelling as it was when it was first published. That’s partly because it’s so thick with ambiguity—and so resistant to easy interpretation.
Is it really ambiguous? I mean, when someone calls something frankenfood, they aren’t calling it “ethically ambiguous food.”
It’s a fair point. For decades, Frankenstein has been central to discussions in and about bioethics. Perhaps most notably, it frequently crops up as a reference point in discussions of genetically modified organisms, where the prefix Franken- functions as a sort of convenient shorthand for human attempts to meddle with the natural order. Today, the most prominent flashpoint for those anxieties is probably the clustered regularly interspaced short palindromic repeats, or CRISPR, gene-editing technique [emphasis mine]. But it’s really oversimplifying to suggest Frankenstein is a cautionary tale about monkeying with life.
As we’ll see throughout this month on Futurography, it’s become a lens for looking at the unintended consequences of things like synthetic biology, animal experimentation, artificial intelligence, and maybe even social networking. Facebook, for example, has arguably taken on a life of its own, as its algorithms seem to influence the course of elections. Mark Zuckerberg, who’s sometimes been known to disavow the power of his own platform, might well be understood as a Frankensteinian figure, amplifying his creation’s monstrosity by neglecting its practical needs.
But this book is almost 200 years old! Surely the actual science in it is bad.
Shelley herself would probably be the first to admit that the science in the novel isn’t all that accurate. Early in the novel, Victor Frankenstein meets with a professor who castigates him for having read the wrong works of “natural philosophy.” Shelley’s protagonist has mostly been studying alchemical tomes and otherwise fantastical works, the sort of things that were recognized as pseudoscience, even by the standards of the day. Near the start of the novel, Frankenstein attends a lecture in which the professor declaims on the promise of modern science. He observes that where the old masters “promised impossibilities and performed nothing,” the new scientists achieve far more in part because they “promise very little; they know that metals cannot be transmuted and that the elixir of life is a chimera.”
Is it actually about bad science, though?
Not exactly, but it has been read as a story about bad scientists.
Ultimately, Frankenstein outstrips his own teachers, of course, and pulls off the very feats they derided as mere fantasy. But Shelley never seems to confuse fact and fiction, and, in fact, she largely elides any explanation of how Frankenstein pulls off the miraculous feat of animating dead tissue. We never actually get a scene of the doctor awakening his creature. The novel spends far more dwelling on the broader reverberations of that act, showing how his attempt to create one life destroys countless others. Read in this light, Frankenstein isn’t telling us that we shouldn’t try to accomplish new things, just that we should take care when we do.
This speaks to why the novel has stuck around for so long. It’s not about particular scientific accomplishments but the vagaries of scientific progress in general.
Does that make it into a warning against playing God?
It’s probably a mistake to suggest that the novel is just a critique of those who would usurp the divine mantle. Instead, you can read it as a warning about the ways that technologists fall short of their ambitions, even in their greatest moments of triumph.
Look at what happens in the novel: After bringing his creature to life, Frankenstein effectively abandons it. Later, when it entreats him to grant it the rights it thinks it deserves, he refuses. Only then—after he reneges on his responsibilities—does his creation really go bad. We all know that Frankenstein is the doctor and his creation is the monster, but to some extent it’s the doctor himself who’s made monstrous by his inability to take responsibility for what he’s wrought.
I encourage you to read Brogan’s piece in its entirety and perhaps supplement the reading. Mary Shelley has a pretty interesting history. She ran off with Percy Bysshe Shelley who was married to another woman, in 1814 at the age of seventeen years. Her parents were both well known and respected intellectuals and philosophers, William Godwin and Mary Wollstonecraft. By the time Mary Shelley wrote her book, her first baby had died and she had given birth to a second child, a boy. Percy Shelley was to die a few years later as was her son and a third child she’d given birth to. (Her fourth child born in 1819 did survive.) I mention the births because one analysis I read suggests the novel is also a commentary on childbirth. In fact, the Frankenstein narrative has been examined from many perspectives (other than science) including feminism and LGBTQ studies.
Getting back to the science fiction end of things, the next part of the Futurography series is titled “A Cheat-Sheet Guide to Frankenstein” and that too is written by Jacob Brogan with a publication date of Jan. 3, 2017,

‘Franken’ and CRISPR
The first essay is in a Jan. 6, 2016 article by Kay Waldman focusing on the ‘franken’ prefix (Note: links have been removed),
In a letter to the New York Times on June 2, 1992, an English professor named Paul Lewis lopped off the top of Victor Frankenstein’s surname and sewed it onto a tomato. Railing against genetically modified crops, Lewis put a new generation of natural philosophers on notice: “If they want to sell us Frankenfood, perhaps it’s time to gather the villagers, light some torches and head to the castle,” he wrote.
William Safire, in a 2000 New York Times column, tracked the creation of the franken- prefix to this moment: an academic channeling popular distrust of science by invoking the man who tried to improve upon creation and ended up disfiguring it. “There’s no telling where or how it will end,” he wrote wryly, referring to the spread of the construction. “It has enhanced the sales of the metaphysical novel that Ms. Shelley’s husband, the poet Percy Bysshe Shelley, encouraged her to write, and has not harmed sales at ‘Frank’n’Stein,’ the fast-food chain whose hot dogs and beer I find delectably inorganic.” Safire went on to quote the American Dialect Society’s Laurence Horn, who lamented that despite the ’90s flowering of frankenfruits and frankenpigs, people hadn’t used Frankensense to describe “the opposite of common sense,” as in “politicians’ motivations for a creatively stupid piece of legislation.”
A year later, however, Safire returned to franken- in dead earnest. In an op-ed for the Times avowing the ethical value of embryonic stem cell research, the columnist suggested that a White House conference on bioethics would salve the fears of Americans concerned about “the real dangers of the slippery slope to Frankenscience.”
All of this is to say that franken-, the prefix we use to talk about human efforts to interfere with nature, flips between “funny” and “scary” with ease. Like Shelley’s monster himself, an ungainly patchwork of salvaged parts, it can seem goofy until it doesn’t—until it taps into an abiding anxiety that technology raises in us, a fear of overstepping.
Waldman’s piece hints at how language can shape discussions while retaining a rather playful quality.
Since its publication nearly 200 years ago, Shelley’s gothic novel has been read as a cautionary tale of the dangers of creation and experimentation. James Whale’s 1931 film took the message further, assigning explicitly the hubris of playing God to the mad scientist. As his monster comes to life, Dr. Frankenstein, played by Colin Clive, triumphantly exclaims: “Now I know what it feels like to be God!”
The admonition against playing God has since been ceaselessly invoked as a rhetorical bogeyman. Secular and religious, critic and journalist alike have summoned the term to deride and outright dismiss entire areas of research and technology, including stem cells, genetically modified crops, recombinant DNA, geoengineering, and gene editing. As we near the two-century commemoration of Shelley’s captivating story, we would be wise to shed this shorthand lesson—and to put this part of the Frankenstein legacy to rest in its proverbial grave.
The trouble with the term arises first from its murkiness. What exactly does it mean to play God, and why should we find it objectionable on its face? All but zealots would likely agree that it’s fine to create new forms of life through selective breeding and grafting of fruit trees, or to use in-vitro fertilization to conceive life outside the womb to aid infertile couples. No one objects when people intervene in what some deem “acts of God,” such as earthquakes, to rescue victims and provide relief. People get fully behind treating patients dying of cancer with “unnatural” solutions like chemotherapy. Most people even find it morally justified for humans to mete out decisions as to who lives or dies in the form of organ transplant lists that prize certain people’s survival over others.
So what is it—if not the imitation of a deity or the creation of life—that inspires people to invoke the idea of “playing God” to warn against, or even stop, particular technologies? A presidential commission charged in the early 1980s with studying the ethics of genetic engineering of humans, in the wake of the recombinant DNA revolution, sheds some light on underlying motivations. The commission sought to understand the concerns expressed by leaders of three major religious groups in the United States—representing Protestants, Jews, and Catholics—who had used the phrase “playing God” in a 1980 letter to President Jimmy Carter urging government oversight. Scholars from the three faiths, the commission concluded, did not see a theological reason to flat-out prohibit genetic engineering. Their concerns, it turned out, weren’t exactly moral objections to scientists acting as God. Instead, they echoed those of the secular public; namely, they feared possible negative effects from creating new human traits or new species. In other words, the religious leaders who called recombinant DNA tools “playing God” wanted precautions taken against bad consequences but did not inherently oppose the use of the technology as an act of human hubris.
She presents an interesting argument and offers this as a solution,
The lesson for contemporary science, then, is not that we should cease creating and discovering at the boundaries of current human knowledge. It’s that scientists and technologists ought to steward their inventions into society, and to more rigorously participate in public debate about their work’s social and ethical consequences. Frankenstein’s proper legacy today would be to encourage researchers to address the unsavory implications of their technologies, whether it’s the cognitive and social effects of ubiquitous smartphone use or the long-term consequences of genetically engineered organisms on ecosystems and biodiversity.
Some will undoubtedly argue that this places an undue burden on innovators. Here, again, Shelley’s novel offers a lesson. Scientists who cloister themselves as Dr. Frankenstein did—those who do not fully contemplate the consequences of their work—risk later encounters with the horror of their own inventions.
At a guess, Venkataraman seems to be assuming that if scientists communicate and make their case that the public will cease to panic with reference moralistic and other concerns. My understanding is that social scientists have found this is not the case. Someone may understand the technology quite well and still oppose it.
Frankenstein and anti-vaxxers
The Jan. 16, 2017 essay by Charles Kenny is the weakest of the lot, so far (Note: Links have been removed),
In 1780, University of Bologna physician Luigi Galvani found something peculiar: When he applied an electric current to the legs of a dead frog, they twitched. Thirty-seven years later, Mary Shelley had Galvani’s experiments in mind as she wrote her fable of Faustian overreach, wherein Dr. Victor Frankenstein plays God by reanimating flesh.
And a little less than halfway between those two dates, English physician Edward Jenner demonstrated the efficacy of a vaccine against smallpox—one of the greatest killers of the age. Given the suspicion with which Romantic thinkers like Shelley regarded scientific progress, it is no surprise that many at the time damned the procedure as against the natural order. But what is surprising is how that suspicion continues to endure, even after two centuries of spectacular successes for vaccination. This anti-vaccination stance—which now infects even the White House—demonstrates the immense harm that can be done by excessive distrust of technological advance.
Kenny employs history as a framing device. Crudely, Galvani’s experiments led to Mary Shelley’s Frankenstein which is a fable about ‘playing God’. (Kenny seems unaware there are many other readings of and perspectives on the book.) As for his statement ” … the suspicion with which Romantic thinkers like Shelley regarded scientific progress … ,” I’m not sure how he arrived at his conclusion about Romantic thinkers. According to Richard Holmes (in his book, The Age of Wonder: How the Romantic Generation Discovered the Beauty and Terror of Science), their relationship to science was more complex. Percy Bysshe Shelley ran ballooning experiments and wrote poetry about science, which included footnotes for the literature and concepts he was referencing; John Keats was a medical student prior to his establishment as a poet; and Samuel Taylor Coleridge (The Rime of the Ancient Mariner, etc.) maintained a healthy correspondence with scientists of the day sometimes influencing their research. In fact, when you analyze the matter, you realize even scientists are, on occasion, suspicious of science.
As for the anti-vaccination wars, I wish this essay had been more thoughtful. Yes, Andrew Wakefield’s research showing a link between MMR (measles, mumps, and rubella) vaccinations and autism is a sham. However, having concerns and suspicions about technology does not render you a fool who hasn’t progressed from 18th/19th Century concerns and suspicions about science and technology. For example, vaccines are being touted for all kinds of things, the latest being a possible antidote to opiate addiction (see Susan Gados’ June 28, 2016 article for ScienceNews). Are we going to be vaccinated for everything? What happens when you keep piling vaccination on top of vaccination? Instead of a debate, the discussion has devolved to: “I’m right and you’re wrong.”
For the record, I’m grateful for the vaccinations I’ve had and the diminishment of diseases that were devastating and seem to be making a comeback with this current anti-vaccination fever. That said, I think there are some important questions about vaccines.
Kenny’s essay could have been a nuanced discussion of vaccines that have clearly raised the bar for public health and some of the concerns regarding the current pursuit of yet more vaccines. Instead, he’s been quite dismissive of anyone who questions vaccination orthodoxy.
