Dorsal Grasper provides an intuitive, collaborative grasping approach February 10, 2025 by Marni Ellery More than 15 million people worldwide are living with spinal cord injury (SCI), which can affect their sensory and motor functions below the injury level. For individuals with SCI between C5 and C7 cervical levels, this can mean paralysis affecting their limbs and limited voluntary finger and wrist flexion, making it difficult to grasp large, heavy objects. c The Dorsal Grasper, with its supernumerary robotic fingers, can expand the range of graspable objects and workspace. (Photo by Adam Lau/Berkeley Engineering) Another unique feature is the device’s use of robotic fingers to grasp with the back of the hand. Today, robotic wearables often fit around the person’s fingers, which creates a tension between what the person and the robot each want to do. With supernumerary grasping, both the person and robot are free to act as they see fit. And while grasping with the back of the hand may look a little silly, we believe it has great advantages that could one day allow the Dorsal Grasper to be an accessible and effective device. Drew: This population also generally uses wheelchairs to get around. So it can be hard to approach certain surfaces head-on, like counters or the refrigerator, to grab something, given that the legs are in the way. And with limited trunk control and overall body mobility, that kind of graspable workspace, or being able to reach things off a counter, is really restricted. This device stands out in that you can grasp with one hand pretty much anywhere you can reach that arm, which greatly expands your workspace. And you can grasp larger objects by using the supernumerary robotic fingers. What did you learn from your latest in-lab tests of the Dorsal Grasper? Jungpyo: Based on our in-lab testing with the Dorsal Grasper, we found that subjects could reach their hand out and rotate their hand a lot. So they could simply rotate their head to see the location and then easily grasp the object. This was possible because the robotic finger could be controlled with just wrist extension, something they use all the time. In follow-up interviews, many subjects mentioned that this control method made operating the device feel really intuitive. Hannah: And we achieved such intuitive operation without relying on any fancy components, like EMG [electromyography] sensors or neural interfaces. Jungpyo: The person is a partner, controlling the robotic finger and wrist extension. For example, sometimes the force of the robotic finger is not enough to grasp a heavy object. In that case, a person can extend their wrist more and increase grasping force, so they can successfully achieve this grasping. And if we want to drop an object of any size, we can simply release our wrist and grasping force and drop the object immediately, without waiting for a robotic response. Compared to a fully robotic system, the Dorsal Grasper allows for a faster response. How does the Dorsal Grasper help advance the field of assistive technology? Drew: A lot of devices seek to replace or do the same type of grasping that people are doing already, and the Dorsal Grasper isn’t trying to do that at all. I haven’t seen a lot of devices that adequately support intent detection, which is a significant challenge within the field. With Dorsal Grasper, we’re able to use people’s residual strength and their ability to move their wrist. That partial body power allows the device to read their intention to grab things, which allows for fewer false positives, or fewer accidental grasps. And this then makes it a little bit easier to use the device. And it’s not about just the device, but how we’re assessing the device. We’re not simply creating tasks that highlight the benefits of the robot, but rather we’re looking at ways that this device might be able to help someone in real life. Often this process involves applying my own lived experience as a person with SCI. Drew, you’re about to wrap up your Ph.D. and have been working on this project for many years. What’s changed since you first started this research? Drew: What’s changed the most is how I think about usability and design. I’ve become more critical of how devices can be used and how they can also get in the way. I think a lot of these devices are looked at in a very narrow scope of, “here’s a couple sets of tasks that we’re going to demonstrate in a lab.” But that doesn’t necessarily translate. That said, I truly did not have an appreciation for how difficult of a design challenge this would be: To build something that a user would not only want to wear because it’s comfortable, but also looks okay and isn’t going to stand out in the grocery store or look weird unless they want it to look futuristic — and some users do. Again, it’s going to need to be easy enough to take on and off. Otherwise, it’s going to just get discarded and stuffed in a closet and never get used. What have you learned from working with subjects while testing the Dorsal Grasper? Hannah: We’ve realized that even though someone has tetraplegia, they might still retain a lot of dexterity and ability. And we’ve grown an appreciation for the abilities that a person has in the absence of the device that we’re introducing. Our testing allows us to then see if the introduction of the device might negatively impact them or add new abilities. Drew McPherson and Hannah Stuart demonstrate the newest version of the Dorsal Grasper in the Embodied Dexterity Group’s lab at UC Berkeley. (Photo by Adam Lau/Berkeley Engineering) So we specifically included evaluation of people wearing the device but not using it. This comes back to that idea that Drew was talking about: Do you have to take it on and off? Is it practical? Is it useful? The first thing a device needs to do is not get … Read more

Scientists at the University of Birmingham have analysed Akkermansia muciniphila, a gut bacterium that feeds on mucus sugars, revealing its role in gut health and disease prevention. c A new study has provided the first complete analysis of how Akkermansia muciniphila (AM), a beneficial gut bacterium, breaks down sugars in mucus. The research, published in Nature Microbiology on 31 January, sheds light on the molecular mechanisms behind this process, offering potential implications for gut health and disease management. Led by Dr Lucy Crouch from the University of Birmingham, the study identified 66 enzymes that AM uses to break down mucin, a key component of the mucus lining in the human gastrointestinal tract. The team used mucus from a pig model to observe how these enzymes function together to completely degrade mucin, marking the first systematic understanding of microbial digestion of O-linked sugars. “This is the first time that we have comprehensively seen how microbes break down the food source O-linked sugars in the gut. These newly characterised enzymes may help us understand the different glycans that humans produce, which can be indicative of disease. “These glycans, and others like them, are receptors for various pathogens and their toxins, such as Shiga toxin. If we can modify them, we may be able to influence disease severity. “We know that AM is a hugely important microbe. Its levels can be a strong indicator of overall health, with lower levels being linked to inflammatory diseases and diabetes. AM is also highly sensitive to dietary fibre intake.” Previous research has shown that AM proteins and membrane extracts have beneficial effects on metabolism and immune regulation. This latest study enhances understanding of how AM interacts with its human host and may open new avenues for microbiome-based therapies.

Imagine a future where the birth of a child could transcend the boundaries of natural biology, offering options beyond what nature dictates. This isn’t the plot of a new science fiction film; it’s a reality that could soon be upon us through the advancements in a groundbreaking technology known as in-vitro gametogenesis (IVG). This innovative approach has the potential to redefine the concepts of fertility and parental choice, promising profound changes in how we conceive new life. c

What if the final moments of life were not marked by silence but by a surge of unseen activity? Imagine a symphony reaching its crescendo—not fading into nothingness, but intensifying in a final burst of energy. This is what scientists have observed in the human brain at the moment of death: a sudden spike in high-frequency brain waves, particularly gamma waves, which are linked to memory, awareness, and consciousness itself. c

Thousands of women will participate in a study to see if AI could be used for early breast cancer detection. Around 700,000 women in the UK will take part in the AI breast cancer trial, according to the DHSC. Thirty testing sites will be involved in the study, each fitted with groundbreaking AI digital screening technology. Any woman who has already booked a routine breast cancer screening with NHS will be invited to participate in the study. c The AI system will work together with radiologists to analyze changes in breast tissue that may indicate the early development of cancer. It will then subsequently refer them for further examination if necessary. If this technology works, it could potentially free up hundreds of specialist practitioners and reduce waiting list times. This new AI breast cancer system is called EDITH (Early Detection using Information Technology in Health). The NIHR has so far provided the study with £11 million in government funding. It’s just one aspect of the current effort to change cancer care in the UK. There, scientists are currently focusing on the exciting potential of using innovative technologies to address one of the nation’s leading killers× The Importance of AI Breast Cancer Research Credit: Pexels The most common type of cancer in women is breast cancer. According to WHO, 2.3 million women were diagnosed with breast cancer in 2022 alone, and there were 670,000 deaths worldwide. At the moment, the National Health Service screens around 2.1 million women for breast cancer every year. This has helped prevent around 1,300 deaths annually – a number that would rise significantly if women were diagnosed earlier. An independent investigation of the NHS revealed that survival rates in the UK were worse than in several similar nations regarding certain cancers.

In fact, it has outperformed doctors in accurate diagnosis on many occasions. For example, a system called MIA was employed to analyze over 10,000 mammograms in an NHS study. MIA managed to flag every case and even identified 11 cancers missed by the doctors. According to the president of the Royal College of Radiologists, Dr. Katherin Halliday, “These results are encouraging and help to highlight the exciting potential AI presents for diagnostics.” She went on to say that there is no doubt that clinical radiologists are indispensable. However, she feels that a clinical radiologist who uses the insights provided by proven AI technologies will become an enormous asset in cancer patient care. Another Norwegian study found that breast cancer risk could be predicted up to six years before a diagnosis using AI screening technologies. Other AI Medical Applications Credit: Pexels AI assists doctors in a number of medical fields, in addition to cancer detection. It can help detect diabetic eye disease in its early stages thus preventing blindness. In general, AI enables doctors to make better decisions and detect illnesses quickly. Mental health professionals employ AI chatbots to help clients deal with their feelings of depression and anxiety. AI also improves scans such as MRIs and CTs, increasing the accuracy of disease identification. These advances demonstrate how artificial intelligence is transforming healthcare and improving outcomes for patients. The Bottom Line on AI Breast Cancer Detection Credit: Pexels Many people think of AI as something that just rewords other people’s ideas and creates funny images. However, AI has been effectively employed in a range of different applications, from military to medical. AI breast cancer technology can potentially revolutionize the way we currently detect and treat this disease. The future of medicine is constantly evolving and AI is playing an important role in shaping it.
