3D Printed, Self-Propelled, Endlessly Programmable Artificial Cilia

For years, scientists have been attempting to engineer tiny, artificial cilia for miniature robotic systems that can perform complex motions, including bending, twisting, and reversing. Building these smaller-than-a-human-hair microstructures typically requires multi-step fabrication processes and varying stimuli to create the complex movements, limiting their wide-scale applications.

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.

A New Kind of 3D Printing

While 3D printing techniques have advanced significantly in the last decade, the technology continues to face a fundamental limitation: objects must be built up layer by layer. But what if they didn't have to be?

Robot Bees to Stimulate Pollination

Two scientists from the UK and the US have been jointly awarded £640,000 to build microrobots that simulate the buzzing of bees. Over three years the scientists will work to build tiny robots that can reproduce the buzzes of pollinating bees.

Towards Building an Artificial Heart

Researchers have developed the first fully autonomous biohybrid fish from human stem-cell derived cardiac muscle cells. The artificial fish swims by recreating the muscle contractions of a pumping heart, bringing researchers one step closer to developing a more complex artificial muscular pump and providing a platform to study heart disease like arrhythmia.

A Soft, Stretchable Thermometer

The next generation of soft robotics, smart clothing and biocompatible medical devices are going to need integrated soft sensors that can stretch and twist with the device or wearer. The challenge: most of the components used in traditional sensing are rigid.

Machine Learning for Morphable Materials

Flat materials that can morph into three-dimensional shapes have potential applications in architecture, medicine, robotics, space travel, and much more. But programming these shape changes requires complex and time-consuming computations.

3D Bioprinted Tissues Can Now be Stored in the Freezer Until Needed

A major obstacle to widespread study and clinical use of 3D tissues is their short shelf-life, which may be anywhere from a just few hours to a few days. As in the case of an organ transplant, a bioprinted tissue must be transported rapidly to the location where it is needed, or it will not be viable.

Deep Learning Dreams up New Protein Structures

Just as convincing images of cats can be created using artificial intelligence, new proteins can now be made using similar tools. In a report in Nature, researchers describe the development of a neural network that "hallucinates" proteins with new, stable structures.

A Persoanlised Exoskeleton for Real-World Walking

Researchers have developed a new approach in which robotic exosuit assistance can be calibrated to an individual and adapt to a variety of real-world walking tasks in a matter of seconds. The bioinspired system uses ultrasound measurements of muscle dynamics to develop a personalized and activity-specific assistance profile for users of the exosuit.

All About Eve: AI Model to Interpret Human Gene Variants

Researchers have designed an AI tool called EVE (Evolutionary model of Variant Effect), which uses a sophisticated type of machine learning to detect patterns of genetic variation across hundreds of thousands of nonhuman species and then use them to make predictions about the meaning of variations in human genes.

New Programmable Gene Editing Proteins Found Outside of CRISPR System

Within the last decade, scientists have adapted CRISPR systems from microbes into gene editing technology, a precise and programmable system for modifying DNA. Now, scientists have discovered a new class of programmable DNA modifying systems called OMEGAs (Obligate Mobile Element Guided Activity), which may naturally be involved in shuffling small bits of DNA throughout bacterial genomes.

Astronomers Create the First 3D Printed Stellar Nurseries

Astronomers can't touch the stars they study, but astrophysicists are using 3-dimensional models that fit in the palm of the hand to unravel the structural complexities of stellar nurseries, the vast clouds of gas and dust where star formation occurs.

Paving the Way for Small but Mighty Robots

An interdisciplinary team of roboticists, engineers and biologists have modeled the mechanics of the mantis shrimp's punch and built a robot that mimics the movement. The research sheds light on the biology of these pugnacious crustaceans and paves the way for small but mighty robotic devices.

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.
