Ultrasound-activated hydrogel gives implants a charge
An energy harvesting solution converts ultrasound power into electric energy to wirelessly power implants through the skin.
These contact lenses are designed to correct color blindness
Plasmonic metasurfaces embedded into commercially available rigid gas permeable contact lenses manipulate light and shift incorrectly perceived pigments closer to the original colors.
Startup puts the brain back into the audio experience
One key distinction is that the brain is actively engaged when listening live but passive when listening to a recording.
A fast, portable assay for coronavirus screening
The nucleic acid test has been tested in hospitals and laboratories in China, demonstrating 97% accuracy with 99% specificity.
New vaccine delivery method negates the need for refrigeration
Suspending vaccines in a lightweight film eliminates refrigeration requirements and could cost-effectively expand global access to these medicines.
3D printing method creates in vitro environment for studying glioblastoma treatment
Researchers from RPI, Northeastern University and the Icahn School of Medicine at Mount Sinai created a new method that combines bioprinting and imaging of glioblastoma cells in a cost-effective way.
Nanodrills target drug-resistant bacteria disease-causing cells
Light-activated molecular drills effectively kill targeted cells and may find potential use in treating human skin diseases.
Video: Blastoff to the ISS for heart cell study
The cosmic cardiac mission will examine the effects of microgravity environments on heart health and translate findings into improved treatments for heart muscle diseases.
Study: Formulating new antibiotics with metals
Previously unexplored compounds containing silver, manganese, zinc and other metals exert antibacterial and antifungal activity.
Sequencing platform speeds coronavirus characterization
While not designed for diagnostic use, the method provides insight into the properties of the isolated virus by application of next-generation sequencing.
Watch magnetized microbots automate microfluidic assays
Tiny ferrobots about 2 mm in diameter can coordinate and expedite the manipulation of fluid droplets as required in medical diagnostic assays, drug development and other uses.
A pediatric heart valve with room to grow
An artificial valve can be expanded via a minimally invasive transcatheter procedure to accommodate the growing heart and associated increases in blood flow volume.
AI tool diagnoses coronavirus in patient CT scans in just 20 seconds
The research arm of Chinese tech company Alibaba has developed an algorithm capable of diagnosing the coronavirus in seconds based on a patient's computerized tomography (CT) scans.
As climate warms, groundwater depletion will increase, study says
The estimated groundwater loss on the low side could be about 119 million cubic meters, or roughly enough to fill Lake Powell in Arizona four times or one quarter of Lake Erie's volume.
Pill-sized device heats up point-of-care diagnostics
A miniaturized chemical heater devised at the University of Toronto can offer a low-cost, field-portable solution for diagnostic testing in resource-limited areas.
Watch: Soft robot gently handles jellyfish to keep them calm
Researchers from the American Museum of National History found that soft robotic fingers can be used to conduct undersea research without stressing out delicate deep-sea animals.
A smart contact lens of many colors
The lens changes color to signal that the wearer suffers from glaucoma or xerophthalmia, an abnormally dry eye condition.
Watch: Better microneedle barbs are 4D-printed
Microneedles with improved tissue adhesion performance have been 4D printed to facilitate minimally invasive drug administration.
A conductive cardiac patch for damaged hearts
The patch was demonstrated to withstand repeated stretching and to incorporate electroconductive properties that mimic those of human heart tissue.
Bioengineers get into the 3D-printing groove
Researchers at Rice University have developed a 3D-printing method that yields solid plastic implants incorporating different types of living cells.
