New Miniature Heart Could Help Speed Heart Disease Cures
An interdisciplinary team of engineers, biologists, and geneticists has developed a new way of studying the heart: they've built a miniature replica of a heart chamber from a combination of nanoengineered parts and human heart tissue. There are no springs or external power sources—like the real thing, it just beats by itself, driven by the live heart tissue grown from stem cells.

Tiny Robot Earns World Record
The creator hopes his robots can someday be used to solve tricky engineering problems by emulating talented creatures like squid or mice that can seamlessly squeeze themselves like liquid into tight places. Biology, particularly insects, still surpass their robotic counterparts in almost every aspect, but he hopes to develop robots in the next decade that are significantly better at mimicking natural systems.

3D Printed, Biocompatible Graft Could Repair Damaged Ear Drum
The PhonoGraft device is a 3D-printed, biocompatible graft that could be implanted to repair a damaged eardrum. If its clinical development is successful, the PhonoGraft technology could mitigate the pain, drainage, and hearing loss associated with ear drum perforations that affect millions of individuals worldwide.

Low Cost Device For Consumers to Home Test Themselves for SARS-CoV-2
With the Delta variant wreaking havoc on unvaccinated populations and COVID-19 cases spiking around the world, the pandemic is far from over. Despite the impressively fast development of SARS-CoV-2 diagnostic tests over the last year and a half, the vast majority of patient samples must still be sent to a lab for processing, which slows down the pace of COVID-19 case tracking. If a sample is to be tested for a specific variant of the virus, it must be genetically sequenced, which takes even more time and resources.

Cutting Surgical Robots Down to Size
Recently, surgical robots have started to appear in operating rooms to further assist surgeons by allowing them to manipulate multiple tools at once with greater precision, flexibility, and control than is possible with traditional techniques. However, these robotic systems are extremely large, often taking up an entire room, and their tools can be much larger than the delicate tissues and structures on which they operate.

Soft Robotic Exosuit for Stroke Survivors
To allow stroke patients to recover, many rehabilitation centers have looked to robotic exoskeletons. But although there are now a range of exciting devices that are enabling people to walk again who initially were utterly unable to do so, there remains significant active research trying to understand how to best apply wearable robotics for rehabilitation after stroke.

Soft Robotic Fingers Gently Grasp Deep-Sea Jellyfish
Marine biologists have adopted "soft robotic linguine fingers" as tools to conduct their undersea research. Scientists found that jellyfish held by ultra-soft robotic fingers expressed significantly fewer stress-related genes than when braced by traditional submersible grippers. Shaped like the famous noodles, this new robotic technology allows for the collection of ecological data in a gentler, less invasive manner.

Printing Objects That Can Incorporate Living Organisms
A method for printing 3D objects that can control living organisms in predictable ways has been developed. The technique may lead to 3D printing of biomedical tools, such as customized braces, that incorporate living cells to produce therapeutic compunds such as painkillers or topical treatments, the researchers say.
