Skin Monitoring Apps Fail to Detect Melanomas

Artificial intelligence-based health technologies are rapidly moving from the lab—where AI has routinely out-performed doctors—into the hands of consumers. Publicly available skin cancer detection apps, such as SkinVision, use AI-based analysis to determine if a new or changing mole is a source of concern or nothing to worry about. Yet according to a new analysis … Continue reading Skin Monitoring Apps Fail to Detect Melanomas

Researchers Can Now Interrogate Body-on-Chip

Scientists have just announced the completion of a lofty DARPA challenge to integrate 10 human organs-on-chips in an automated system to study how drugs work in the body. The technology provides an alternative to testing drugs on humans or other animals. Referred to as the “Interrogator” by its developers, the system links up to ten different human … Continue reading Researchers Can Now Interrogate Body-on-Chip

AI-Designed 'Living Robots' Crawl, Heal Themselves

Biological organisms have certain useful attributes that synthetic robots do not, such as the abilities to heal, adapt to new situations, and reproduce. Yet molding biological tissues into robots or tools has been exceptionally difficult to do: Experimental techniques, such as altering a genome to make a microbe perform a specific task, are hard to control and not … Continue reading AI-Designed 'Living Robots' Crawl, Heal Themselves

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

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
