3D-printed tissue featuring fluid channels mimics real organs for surgical training
Researchers have developed a new 3D-printing method for creating realistic human tissue structures that could one day be used in the making of human models to train surgeons and doctors.
Smart glasses monitor health through blinking
The team believes that the device could potentially pave the way for assessing fatigue, mental workload and eye-related health issues in real-world settings, such as long-haul trucking or in the office.
Rethinking reach: Designing assistive exoskeletons for the upper limbs
Aging populations face rising rates of stroke and degenerative conditions requiring long-term rehabilitation, while industrial and service workers contend with fatigue and repetitive strain from overhead tasks. These demands highlight the need for technologies that extend physical capacity while preserving user autonomy.
Smart microfibers turn ordinary objects into health monitors and energy sources
The team sought to develop fibers thinner than a human hair that can be tuned on-demand to add sensing, energy conversion and electronic connectivity capabilities to assorted objects of various shapes and surface textures — like glass, plastic and leather.
New drug-delivery cartilage material shows promise for arthritis treatment
The team suggests that this development could pave the way for longer-lasting, targeted arthritis treatments that automatically respond to flare-ups, sensing when something within the body is wrong and delivering treatment precisely where it is needed.
Oyster-inspired adhesive bonds broken bones, potentially replacing metal implants
The medical adhesive, dubbed “Bone-02,” is designed to repair broken bones quickly and without the need for metal plates, screws or major surgeries.
Scientists created bone substitute from 3D-printed glass
During trials conducted in rabbits, the material sustained bone cell growth outperforming both regular glass and a commercially available bone substitute.
UV light neutralizes airborne allergens in 30 minutes
Researchers from the University of Colorado Boulder suggest that ultraviolet (UV) light can neutralize airborne allergens in just 30 minutes.
New biosensor tracks airborne viruses in real-time
The developers of the biosensor suggest that there is a host of possible applications for the technology such as detecting bacteria in hospitals, schools and on public transportation.
New bubble-driven bots could replace traditional needle injections
The idea behind the new technique is cavitation, which is the sudden collapse of bubbles in liquid. The energy produced from this process enabled the team to build tiny robots — dubbed “jumpers” — that move significant distances relative to their size.
New wearable patch performs diagnostics using sweat, not blood
The smart patch can precisely observe internal changes through sweat when attached to the body where it can simultaneously and in real-time analyze multiple metabolites.
"Bone-gun" can generate bone grafts directly onto fractures in animals
The so-called bone gun has already been trialed in rabbits, quickly creating complex bone implants without having to prefabricate in advance.
New study finds natural maple polyphenol inhibits bacteria that cause tooth decay
Researchers from the University of Wyoming suggest that a natural compound from maple could potentially combat Streptococcus mutans, which is the bacteria associated with tooth decay.
Study: Chemical fingerprints can trace origins of stolen and counterfeit drugs
The potential new weapon against pharmaceutical counterfeiting may be on the way, promising to distinguish seemingly identical medicines at the molecular level.
Paving the way for suture-free tissue repair and improved healing
Tissium features flexible, biocompatible polymers that conform to and subsequently attach to surrounding tissues to repair torn tissue after being activated using blue light.
Bacterial cellulose dressing stops bleeding fast, boosts burn wound treatment
Researchers turned to BC for use as a wound dressing material because of its microporous structure, mechanical strength, breathability and biocompatibility.
3D-printed heart patch boosts tissue repair using living-cell hydrogel, structural mesh
The team developed a 3D-printed heart patch for intraventricular implantation to serve as an alternative to the bovine pericardial patches (BPPs) currently in use but that have significant disadvantages.
New hydrogel adheres underwater, strong enough to hold 139 pounds
The hydrogel material is capable of instant, strong and repeatable adhesion across diverse surfaces and underwater.
Toothpaste with human hair protein promises to repair enamel and prevent decay
According to the toothpaste's developers, keratin, a protein found in hair, skin and wool, can reportedly restore enamel and prevent early tooth decay.
From powder to prototype: Laser sintering accelerates medical device innovation
SLS enables the creation of durable prototypes that can withstand mechanical testing and real-world handling, making it particularly useful for surgical tools, orthotic components and patient-specific models.
