A research team at the University of California San Diego have developed a smartphone attachment that can provide information on changes in pupil size, which can be used to assess neurological phenomena, such as traumatic brain injury and Alzheimer’s disease. Such changes in pupil size have been difficult to characterize in the past in those […]

CRISPR-Equipped Bacteria Detect Tumors
Researchers at the University of California San Diego have created a bacterial sentinel system that can alert clinicians to the presence of tumors. The technology takes advantage of the specificity of the CRISPR system and the tendency of bacteria to uptake fragments of DNA from their environment. Termed “Cellular Assay for Targeted CRISPR-discrimi (Read more...)
Tiny Patch for Cardiac Ultrasound Imaging
Engineers at the University of California San Diego have developed a wearable ultrasound system for cardiac imaging. The postage stamp-sized patch can be worn on the skin of the chest and uses AI and ultrasound waves to perform advanced imaging of the heart. The technology can even be worn to perform cardiac ultrasound imaging during […]
Algae-Based Microrobots Deliver Antibiotics within Lungs
Researchers at the University of California San Diego have developed a microrobot system to treat bacterial pneumonia. The microrobots consist of living algal cells that can swim very effectively in biological fluids, allowing them to navigate throughout the lungs and deliver drugs to difficult-to-reach areas. The algal cells are studded with antib (Read more...)
Wearable Uses Microneedles to Track Metabolism
A team of researchers at the University of California San Diego created a wearable device that uses a disposable microneedle patch to continuously sample and analyze interstitial fluid. The wearable can measure glucose, alcohol, and lactate levels, all of which could be useful information for patients with diabetes. The disposable patch is attached (Read more...)
Device Makes Diffuse Ultrasound Waves for Intracranial Applications
Researchers at the University of California San Diego created an ultrasound transducer that is intended to provide safer ultrasound treatment when working inside the brain. Ultrasound has significant therapeutic potential for various ailments that originate in the brain, including epilepsy, and next-level sonogenetics involves targeting various cel (Read more...)
Flu Virus-Inspired Nanoparticles for mRNA Delivery
Researchers at the University of California San Diego developed a new delivery technique for mRNA. The method involves flu virus-inspired nanoparticles that can escape endosomes, the acidic vesicles that engulf and destroy materials that attempt to enter cells. The nanoparticles contain a protein receptor that allows them to unlock the endosomes an (Read more...)
