This AI powered prosthetic arm understands what you think. Muscle-controlled prosthetic limbs that patients with amputations across the globe currently use have various limitations and challenges. Good quality prosthetics parts are cumbersome, come with a complex setup, and require patients to undergo training for several months to learn their use. Interestingly, a new technology proposed by a team of researchers at the University of Minnesota (UMN) can overcome all such challenges.
It may sound like science-fiction, but the researchers claim that the new technology would allow patients to control robotic body parts using their thoughts. By employing artificial intelligence and machine learning, the researchers at UMN have developed a portable neuroprosthetic hand. The robotic hand comes equipped with a nerve implant linked to the peripheral nerve in a patient’s arm.
Explaining the significance of their neuroprosthetic innovation, project collaborator and UMN neuroscientist Edward Keefer said, “We are well along the way toward allowing upper limb amputees at least, and other people in the future, to have totally natural and intuitive control of their prosthetic devices.” ## THE NEUROPROSTHETIC HAND IS DIFFERENT FROM YOUR REGULAR PROSTHETIC LIMBS
The prosthetic body parts currently available on the market detect shoulder, chest, or muscle movement. They have sensors to recognize signals in specific regions of the human body. Therefore, every time a patient wants to move his hand, he is required to trigger his body muscles. Adapting to such muscle-driven limb movement is not easy for patients, and many such devices are not suitable for physically weak individuals.
Second time’s the charm.

Progress on reducing carbon emissions has been slow making achieving interim 2030 targets elusive, let alone hitting net-zero by 2050.
Preparedness For Emerging Diseases & Zoonoses — Dr. Maria Van Kerkhove, Ph.D., Emerging Diseases and Zoonoses Unit Head, World Health Organization, (WHO)
Dr. Maria Van Kerkhove, Ph.D., (https://www.imperial.ac.uk/people/m.vankerkhove) is an infectious disease epidemiologist who serves as the technical lead for the COVID-19 response at the World Health Organization (https://www.who.int/en/), where she develops guidance, training programs, and information products for the continuously evolving state of the pandemic, as well serving as the Emerging Diseases and Zoonoses Unit Head.
Dr. Van Kerkhove began her journey in global health given her interest in viruses and how they infect and impact both humans and animals. She received her undergraduate degree in biological sciences from Cornell University, her master’s degree in epidemiology from Stanford University, and a PhD in infectious disease epidemiology from the London School of Tropical Hygiene and Medicine where she authored her PhD on pathogenic avian influenza H5N1 in Cambodia.

Just as electromagnetic energy is quantized into propagating photons, acoustic energy propagates in quanta called phonons. The science of photon behaviour – called quantum electrodynamics – is an important branch of modern physics because it provides a relativistic description of the interaction of light with matter. Scientists have used the theory in a variety of applications such as atomic clocks and quantum computation. In recent years, scientists have begun applying some of the same concepts to phonons in a field called quantum acoustodynamics. Last year, for example, two groups independently used laser-based measurements to entangle the oscillations of membranes in cavities.
