Robotic exoskeletons are an increasingly popular method for assisting human labor in the workplace. Those that specifically support the back, however, can result in bad lifting form by the wearer. To combat this, researchers at the University of Michigan have built a pair of robot knee exoskeletons, using commercially available drone motors and knee braces.

“Rather than directly bracing the back and giving up on proper lifting form,” U-M professor Robert Gregg notes, “we strengthen the legs to maintain it.”

Test subjects were required to move a 30-pound kettlebell up and down a flight of stairs. Researchers note that the tech helped them maintain good lifting form, while lifting more quickly.

A research team led by Prof. Ye Hong from the University of Science and Technology of China has developed an alumina ceramic bionic wick with finger-like pores inspired by the stomatal array of natural leaves. Their research is published in Langmuir.

As the performance of electronic chips continues to improve, their also increases, posing new challenges for cooling strategies. Loop heat pipes (LHPs) are a compelling cooling solution due to their high heat transfer capability, antigravity heat transfer, and absence of moving parts.

However, the differing requirements for flow resistance and capillary force make designing the structure of the capillary wick within an LHP challenging. Specifically, larger pores are needed for gaseous working fluids to reduce flow resistance, while smaller pores are necessary to provide sufficient capillary force for liquid suction.

Scientists at the Max-Planck-Institute for Intelligent Systems (MPI-IS) have developed hexagon-shaped robotic components, called modules, that can be snapped together LEGO-style into high-speed robots that can be rearranged for different capabilities.

The team of researchers from the Robotic Materials Department at MPI-IS, led by Christoph Keplinger, integrated artificial muscles into hexagonal exoskeletons that are embedded with magnets, allowing for quick mechanical and electrical connections.

The team’s work, “Hexagonal electrohydraulic modules for rapidly reconfigurable high-speed robots” was published in Science Robotics on September 18, 2024.

A team of roboticists at the German Aerospace Center’s Institute of Robotics and Mechatronics finds that combining traditional internal force-torque sensors with machine-learning algorithms can give robots a new way to sense touch.

In their study published in the journal Science Robotics, the group took an entirely new approach to give robots a that does not involve artificial skin.

For living creatures, touch is a two-way street; when you touch something, you feel its texture, temperature and other features. But you can also be touched, as when someone or something else comes in contact with a part of your body. In this new study, the research team found a way to emulate the latter type of touch in a robot by combining internal force-torque sensors with a machine-learning algorithm.

Will artificial intelligence save us or kill us all? In Japan, AI-driven technology promises better lives for an aging population. But researchers in Silicon Valley are warning of untamable forces being unleashed– and even human extinction.

Will artificial intelligence make life better for humans or lead to our downfall? As developers race toward implementing AI in every aspect of our lives, it is already showing promise in areas like medicine. But what if it is used for nefarious purposes?

In Japan, the inventor and scientist behind the firm Cyberdyne is working to make life better for the sick and elderly. Professor Yoshiyuki Sankai’s robot suits are AI-driven exoskeletons used in rehabilitative medicine to help stroke victims and others learn to walk again. But he doesn’t see the benefits of AI ending there; he predicts a future world where AIs will live in harmony with humans as a new, benevolent species.

Yet in Silicon Valley, the cradle of AI development, there is an unsettling contradiction: a deep uncertainty among many developers about the untamable forces they are unleashing. Gabriel Mukobi is a computer science graduate student at Stanford who is sounding the alarm that AI could push us toward disaster– and even human extinction. He’s at the forefront of a tiny field of researchers swimming against the current to make sure AI is safe and beneficial for everyone.

Astronaut John McFall hopes to see an ISS astronaut with a disability fly by 2030 — video.


A European Space Agency (ESA) reserve astronaut, McFall was selected for the program in 2022 based on his experience as a trauma and orthopedic specialist, surgeon and exercise scientist. McFall also has lived experience with a disability as he has used prosthetics regularly since the amputation of his right leg at age 19, following a motorcycle accident. (He even won a bronze medal in the 2008 Paralympics in the 100-meter sprint, class T42.)

A recent study dubbed “Fly!” — in which McFall played a key role — found there would be no major issues to International Space Station missions should an astronaut use a prosthesis on board. There is more work to be done, but the goal is for it all to culminate in flying “someone with a physical disability” to the ISS, McFall told Space.com in an exclusive interview on Aug. 8. “By the end of this decade, hopefully that would have happened.”

Noninvasive braincomputer interfaces could vastly improve brain computer control.


Over the past two decades, the international biomedical research community has demonstrated increasingly sophisticated ways to allow a person’s brain to communicate with a device, allowing breakthroughs aimed at improving quality of life, such as access to computers and the internet, and more recently control of a prosthetic limb. DARPA has been at the forefront of this research.

The state of the art in brain-system communications has employed invasive techniques that allow precise, high-quality connections to specific neurons or groups of neurons. These techniques have helped patients with brain injury and other illnesses. However, these techniques are not appropriate for able-bodied people. DARPA now seeks to achieve high levels of brain-system communications without surgery, in its new program, Next-Generation Nonsurgical Neurotechnology (N3).

“DARPA created N3 to pursue a path to a safe, portable neural interface system capable of reading from and writing to multiple points in the brain at once,” said Dr. Al Emondi, program manager in DARPA’s Biological Technologies Office (BTO). “High-resolution, nonsurgical neurotechnology has been elusive, but thanks to recent advances in biomedical engineering, neuroscience, synthetic biology, and nanotechnology, we now believe the goal is attainable.”
