Quantum Dots Encode Vaccine History in the Skin

I remember a faded yellow booklet, about the size of a wallet, that my mother used to pull out once a year at the doctor’s office to record my vaccines. Today, nurses document my children’s vaccination history in electronic health records that will likely follow them to adulthood. To eradicate a disease—such as polio or … Continue reading Quantum Dots Encode Vaccine History in the Skin

Cyberattacks on Medical Devices Are on the Rise—and Manufacturers Must Respond

This is a guest post. The views expressed here are solely those of the author and do not represent positions of IEEE Spectrum or the IEEE. Cyberattacks are increasingly common in the health care industry. As the number of networked medical devices increases, so does the urgency for makers of these devices to understand and mitigate threats to … Continue reading Cyberattacks on Medical Devices Are on the Rise—and Manufacturers Must Respond

With DNA Data Storage, 3D-Printed Bunnies Carry Their Own Blueprints

Every living thing contains DNA that provides the codes for its existence, and now inanimate objects can have that, too. In a paper published today in Nature Biotechnology, researchers described how they 3D printed a bunny-shaped trinket that contained DNA encoding the digital instructions for its fabrication. That means that tomorrow, or a thousand years from now, someone could, with merely a piece of … Continue reading With DNA Data Storage, 3D-Printed Bunnies Carry Their Own Blueprints

Liquid Electrodes Morph Into Flexible Wires for Neural Stimulation

Our nervous system is specialized to produce and conduct electrical currents, so it’s no surprise that gentle electric stimulation has healing powers. Neural stimulation—also known as neuromodulation, bioelectronic medicine, or electroceuticals—is currently used to treat pain, epilepsy, and migraines, and is being explored as a way to combat paralysis, inflammation, and even hair loss. Muscle stimulation can … Continue reading Liquid Electrodes Morph Into Flexible Wires for Neural Stimulation
