Robots with sticky feet
Jet engines can have up to 25,000 individual parts, making regular maintenance a tedious task that can take over a month per engine. Many components are located deep inside the engine and cannot be inspected without taking the machine apart, adding time and costs to maintenance. This problem is not only confined to jet engines, either; many complicated, expensive machines.
Predicting leaky heart valves with 3D printing
Researchers have created a novel 3D printing workflow that allows cardiologists to evaluate how different valve sizes will interact with each patient's unique anatomy, before the medical procedure is actually performed.
Electrical stimulation in the nose induces sense of smell
Physicians have, for the first time, induced a sense of smell in humans by using electrodes in the nose to stimulate nerves in the olfactory bulb, a structure in the brain where smell information from the nose is processed and sent to deeper regions of brain.
Gentle robotic hand for sea life
The open ocean is the largest and least explored environment on Earth, estimated to hold up to a million species that have yet to be described. However, many of those organisms are soft-bodied - like jellyfish, squid, and octopuses - and are difficult to capture for study with existing underwater tools, which all too frequently damage or destroy them. Now, a new device safely traps delicate sea creatures inside a folding polyhedral enclosure and lets them go without harm using a novel, origami-inspired design.
Personalized bio-inks boost healing potential of printable body tissue
Researchers have incorporated platelet-rich plasma into a bio-ink: a 3-D-printed mixture of cells and gel that could eventually become the stuff of skin grafts and regenerative tissue implants.
Molecular Robotics capitalizes on recent explosion of technologies
Collaborations between nanotechnologists, synthetic biologists, and computer scientists create nanoscale tools that could revolutionize fields from cancer diagnostics to materials science.
Colour changing tattoos monitor health
Researchers have developed smart tattoo ink capable of monitoring health by changing color to tell an athlete if they are dehydrated or diabetic.
Robotic system monitors specific neurons
Recording electrical signals from inside a neuron in the living brain can reveal a great deal of information about that neuron's function and how it coordinates with other cells in the brain.
Harvesting the microbiome of athletes
Scientists have now tapped into the microbiome of exceptional runners and rowers, and have identified particular bacteria that may aid athletic performance.
Using ultrasound to trigger on-demand, site-specific pain relief
A novel system uses ultrasound to trigger the release of nerve-blocking agents — injected into specific sites of the body ahead of time — when and where pain relief is needed most.
Building the safe genes toolkit
DARPA created the Safe Genes program to gain a fundamental understanding of how gene editing technologies function; devise means to safely, responsibly, and predictably harness them for beneficial ends; and address potential health and security concerns related to their accidental or intentional misuse.
Soft and stretchy fabric-based sensors for wearable robots
A team of researchers has created a highly sensitive soft capacitive sensor made of silicone and fabric that moves and flexes with the human body to unobtrusively and accurately detect movement.
Personalized cancer vaccine
A personal cancer treatment vaccine that targets distinctive "neoantigens" on tumor cells has been shown to stimulate a potent, safe, and highly specific immune anti-tumor response in melanoma patients.
Tethered soft exosuit reduces metabolic cost of running
Researchers have demonstrated that a tethered soft exosuit can reduce the metabolic cost of running on a treadmill by 5.4%.
Shedding light on how humans walk...with robots
With the recent boom of the robotic exoskeleton industry, more and more patients are being strapped into machines that apply forces to their legs as they walk, gently prodding them to modify their movements by lengthening their strides, straightening their hips, and bending their knees. But, are all patients benefiting from this kind of treatment?
Bionic Eye Technologies
In this profile, Alexis Karandrea reports on correspondence with Richard Birney, the CEO of Bionic Eye Technologies, Inc., and the retinal implant technology they are developing.
Stretchy optical fibers for implanting in the body
Researchers have developed a biocompatible and highly stretchable optical fiber made from hydrogel — an elastic, rubbery material composed mostly of water. The fiber, which is as bendable as a rope of licorice, may one day be implanted in the body to deliver therapeutic pulses of light or light up at the first sign of disease.
Drug-dispensing contact lens
A contact lens designed to deliver medication gradually to the eye could improve outcomes for patients with conditions requiring treatment with eye drops, which are often imprecise and difficult to self-administer.
Tough new hydrogel hybrid doesn't dry out
Engineers have found a way to prevent hydrogels from dehydrating, with a technique that could lead to longer-lasting contact lenses, stretchy microfluidic devices, flexible bioelectronics, and even artificial skin.
Bionic leaf turns sunlight into liquid fuel
The days of drilling into the ground in the search for fuel may be numbered, because if Daniel Nocera has his way, it'll just be a matter of looking for sunny skies.
