  • Digital health predictions for 2022: Looking to a brighter future

    Health is in the throes of some of the most significant changes as systems reel from a variety of rapidly changing environments. Dr Charles Alessi, Chief Clinical Officer at HIMSS, explores lessons learned, as we look cautiously to a better 2022.

  • New Hydrogel Material for Vocal Cord Repair

    Researchers at McGill University developed a tough hydrogel that can resist mechanical forces found in the body. However, the material still provides a friendly environment for encapsulated cells to grow and enables the deep perfusion of blood and other tissue fluids. The injectable biomaterial may be useful in repairing tissues that experience constant mechanical stress,

  • Progesterone Test Wands to Maximize the Chances of Conception: Interview with Sylvia Kang, CEO of Mira

    Mira is a medical device company based in California specializing in technology that helps women maximize their chances of conception and monitor their reproductive health. Fertility problems are on the rise, with sperm counts dropping and many couples having difficulties conceiving. Technology can assist in maximizing the potential of conception by allowing women to track

  • Health Gadgets to Help Beat Sitting All Day

    Whether in front of the computer or TV, driving on long commutes, or attending a sporting event, the average person spends more than 12 hours a day sitting. This can take a serious toll on your body in a variety of ways, but muscle and joint pain can be the most immediately apparent. Sitting all

  • Catheter-Deliverable Biomaterial Sealants: Interview with Natalie Artzi, Co-founder of BioDevek

    BioDevek, a medtech company based in Cambridge, Massachusetts, has developed a biomaterial adhesive that acts to seal internal wounds and incisions. The material is designed to be sprayed through a catheter, and the primary application for the technology so far is to act as a sealant following colonic polyp resection. At present, following polyp resection,

  • Airway Chip as Benchtop Model of Cystic Fibrosis

    Researchers at Harvard’s Wyss Institute created a microfluidic chip that mimics the airway of patients with cystic fibrosis. By including lung airway cells from cystic fibrosis patients within the device, the team was able to reproduce many of the hallmarks of the disease, including a thick mucus layer, inflammation, and bacterial growth. The chip could

  • Laser Kills Multidrug-Resistant Bacteria for Wound and Blood Decontamination

    Scientists at Washington University School of Medicine in St. Louis have developed an ultrashort-pulse laser that can kill multidrug-resistant bacteria and their spores, and without damaging human cells. The laser works by vibrating and breaking protein structures within the bacterial cell, resulting in biochemical disruption and eventual death. The researchers hope that the technique could

  • Wireless Electronic Sensor to Monitor Bone Health

    Engineers and orthopedic specialists at the University of Arizona built an ultra-thin wireless sensor that is designed to monitor bone health over long periods of time. The battery-free device is intended to measure a variety of physiological parameters, such as temperature and bone strain, and could be useful for patients with osteoporosis or to monitor

  • 3D Blood Vessel Map Reveals Location of Stem Cells

    Scientists at Johns Hopkins used a combination of molecular labeling and imaging techniques to create a three-dimensional map of the blood vessels in the mouse skull. Their approach also reveals niches where stem cell populations lurk, which could help researchers to understand how blood vessels and cells behave in various states of disease or injury.

  • Voxel-Based Technique to Streamline Bioprinting

    At the University of Virginia researchers developed a new bioprinting technique based on voxels. Voxels are 3D cubes that form basic building blocks in computer graphics, similar to what pixels are for 2D, and have been popularized by games such as Minecraft. The new technique involves printing discrete spherical blobs of bioink (as the voxels)

  • Fish-Shaped Microrobots to Deliver Chemotherapy to Tumors

    Researchers from the University of Science and Technology of China, working with outside collaborators, have developed shape-shifting microrobots that are designed to be guided to a target area in the body using magnets, and then release a drug cargo in response to the local environment. The application that the researchers have pursued involves guiding the

  • New Technique Generates 3D Images of Bacteria for Antibiotic Susceptibility Testing

    Researchers at the University of Connecticut have developed a highly sensitive imaging sensor that can rapidly and accurately monitor bacterial growth. The technique involves shining laser light through a bacterial sample and taking images at multiple orientations, before reconstructing the diffracted light patterns, to produce a 3D image of the bacterial colony. These 3D images

  • Broadband is the Achilles' heel of telehealth

    The fate of virtual care adoption is tied to the fate of broadband expansion.
