  • Ultrasound Tornado Rapidly Disrupts Blood Clots

    A team of researchers at North Carolina State University have developed an ultrasound transducer that can disrupt blood clots in the brain quickly by creating an ultrasound vortex or ‘tornado’. The transducer is designed to be housed in a catheter that can be advanced through the vasculature until it reaches the site of a blood

  • Nanopore Sensor to Study Protein Aggregation in Neurodegeneration

    Researchers at the University of Arkansas have developed a nanopore sensor to study the aggregation of tau and tubulin protein molecules. These proteins, and specifically their aggregation in the brain, are implicated in neurodegenerative diseases such as Parkinson’s and Alzheimer’s. This nanopore technology aims to allow researchers to study the effects of different environmental conditions,

  • Smart Walking Stick for Visually Impaired People

    Researchers at the University of Colorado at Boulder have developed a smart walking stick that can assist blind or visually impaired people to navigate their environment, from grocery shopping to finding a seat in a busy café. The system employs cameras to visualize the environment and items within it, such as products in a supermarket,

  • Balance Boards to Stay Active in the Offfice: Interview with Joel Heath, CEO of FluidStance 

    Fun and durable, the FluidStance balance board deck can be found at many offices these days as working professionals with desk jobs look for ways to stay active and healthy. Long hours slumped over at a desk means that your muscles remain inactive for long periods of time – a running hypothesis is that long

  • Biobots Use Optogenetic Muscle Actuators for Movement

    Researchers at the University of Illinois at Urbana-Champaign have developed centimeter-scale biobots that combine soft materials, mouse muscle tissue, and wireless electronic components. The tiny devices can be controlled remotely through optogenetics. The muscle within the devices forms an optogenetic actuator and creates movement when exposed to light. The researchers can control this movement remotely

  • Perspective: Physicians should be sole decision-makers

    Predictive analytics in EHRs aren't yet effective enough for clinical decision support at the point of care.

  • Artificial Neuron Uses Ions Like the Real Thing

    Researchers at Linköping University in Sweden have developed artificial neurons that demonstrate 15 of the 20 characteristics of biological neural cells and can communicate with natural neurons in the body. The researchers call their device the “conductance-based organic electrochemical neuron,” or c-OECN, and it is based on materials that can conduct a negative charge, including

  • Hydrogel Scaffold Makes a Living Electrode

    A team of researchers at the Harvard Wyss Institute have developed a soft, hydrogel scaffold that can function as a living electrode for brain-computer interface applications. The researchers used electrically conductive materials and created a porous and flexible scaffold using a freeze-drying process. They then seeded the scaffold with human neural progenitor cells (NPCs) and

  • Bioprinted Eye Tissue to Study Retinal Diseases

    Researchers at the National Eye Institute, which is part of the National Institutes of Health, have created a method to 3D bioprint eye tissue that forms the outer blood-retina barrier. This tissue supports the photoreceptors in the retina and is implicated in the initiation of age-related macular degeneration. The researchers combined different cell types, which

  • Point-Of-Care Biosensor to Detect Oral Cancer

    Researchers at the University of Florida have created a point-of-care biosensor that can rapidly detect a biomarker for oral cancer. The device uses test strips, such as those used in blood glucose tests, to spot cell proliferation regulating inhibitor of protein phosphatase 2A (CIP2A), a protein biomarker that can reveal the presence of oral cancer.

  • Optogenetics Tech for Long-Term Changes in Neuronal Excitability

    Scientists at MIT have developed an optogenetics technique that can lead to long-term changes in neuronal excitability by altering neuronal membrane capacitance. Unlike conventional optogenetics, which involves using light to rapidly activate ion channels on engineered neurons, the new technique relies on a light-sensitive reaction to increase the presence of conductive or insulating polymers in

  • Microbial Fuel Cell Powers Ingestible Devices

    Researchers at Binghamton University have developed a microbial fuel cell that can power ingestible devices, such as cameras, that can detect health issues in the gastrointestinal tract, and specifically within the small intestine. The fuel cell contains dormant Bacillus subtilis endospores that only germinate and become active when they encounter nutrient-rich intestinal fluid. Another check
