You might expect a robot’s heartbeat to be a metallic ticking. But the pulsing in this video isn’t completely artificial: it’s powered by living material, New Scientist reports.
Created by Peter Walters from the University of the West of England in Bristol, UK, and colleagues, the pump uses the gas released by live yeast to generate pressure and distend a membrane, turning it into an… read more

Cornell bioengineers and Weill Cornell Medical College physicians have created an artificial ear that looks and acts like a natural ear, giving new hope to thousands of children born with a congenital deformity called microtia.
They used 3-D printing and injectable gels made of living cells to fashion ears that are practically identical to a human ear.
Over a three-month period, these flexible ears… read more

Scientists have designed an innovative structure containing an intricate microchannel network of simulated blood vessels that solves one of the biggest challenges in regenerative medicine: How to deliver oxygen and nutrients to all cells in an artificial organ or tissue implant that takes days or weeks to grow in the lab prior to surgery.
The new study was performed by a research team led by Jordan Miller, assistant professor… read more

By caging bacteria in microscopic houses, scientists at The University of Texas at Austin are studying how communities of bacteria, such as those found in the human gut and lungs, interact and develop infections.
In a recent experiment, they demonstrated that a community of Staphylococcus aureus, which can cause some skin infections, became more resistant to antibiotics when it was contained within a larger community of Pseudomonas… read more

NASA’s Marshall Space Flight Center is using ”selective laser melting” (SLM) to create intricate metal parts for America’s Space Launch System (SLS) heavy-lift rocket, saving millions in manufacturing costs.
SLM is similar to 3-D printing (additive printing) and is the future of manufacturing, says Ken Cooper, advanced manufacturing team lead at the Marshall Center.
“This machine takes metal powder and uses a high-energy laser to… read more
Engineers at Oregon State University have used additive manufacturing to create an improved type of glucose sensor for patients with Type 1 diabetes, part of a system that should work better, cost less, and be more comfortable for the patient.

A national team of researchers used a combination of 3-D imaging and 3-D printing techniques to create a custom silicone guide implanted with biochemical cues to help nerve regeneration after an injury.
Nerve regeneration is a complex process, which is why regrowth of nerves after injury or disease is very rare and often permanent, according to the Mayo Clinic.
As a test, the researchers used a 3-D scanner… read more

A new kind of fish-shaped microrobots called “microfish” can swim around efficiently in liquids, are chemically powered by hydrogen peroxide, and magnetically controlled. They will inspire a new generation of “smart” microrobots that have diverse capabilities such as detoxification, sensing, and directed drug delivery, said nanoengineers at the University of California, San Diego.
To manufacture the microfish, the researchers used an innovative 3D printing technology they developed,… read more

A group of researchers in China and the U.S. has created a 3D-printed model of a cancerous tumor to help discover new anti-cancer drugs and better understand how tumors develop, grow, and spread throughout the body.
The model consists of a scaffold of fibrous proteins (gelatin, alginate, and fibrin) corresponding to the extracellular matrix (support structure) of a tumor, in the form of a grid structure 10… read more
A kit of 3D-printed anatomical body parts could revolutionize medical education and training, according to its developers at Monash University.
Professor Paul McMenamin, Director of the University’s Centre for Human Anatomy Education, said the simple and cost-effective anatomical kit would dramatically improve trainee doctors’ and other health professionals’ knowledge and could even contribute to the development of new surgical treatments.
“Many medical… read more

University of California, San Diego researchers have 3D-printed a tissue that closely mimics the human liver’s sophisticated structure and function. The new model could be used for patient-specific drug screening and disease modeling and could help pharmaceutical companies save time and money when developing new drugs, according to the researchers.
The liver plays a critical role in how the body metabolizes drugs and produces key proteins, so liver… read more

Researchers at American University have demonstrated the first use of commercial 3D printers to create a structure with active chemistry — in this case, a structure that acts to mitigate pollution.
The researchers added titanium dioxide nanoparticles to standard ABS filament material (used in 3D printers) and extruded a filament that they then used to print a small, sponge-like plastic object on a low-cost Flashforge Creator… read more

UC Berkeley engineers, in collaboration with colleagues at Taiwan’s National Chiao Tung University, have developed a 3D printing process for creating basic electronic components, such as resistors, inductors, capacitors, and integrated wireless electrical sensing systems.
As a test, they printed a wireless “smart cap” for a milk carton that detected signs of spoilage using embedded sensors.
The findings were published Monday, July 20, in… read more
