The bulky pacemakers of the present could be replaced by tiny mechanisms as small as a grain of rice. The secret to shrinking the devices is in how to power them wirelessly.
It's for our health: The Virtual Physiological Human project seeks to create an accurate computer-simulated replica of a patient so that doctors can better predict how certain procedures and medications will work.
Scientists are testing a combined smart pill and skin patch system that will track whether medication was taken, when it was taken, and how the body is responding to it.
The Drinkable Book's pages are made of filters treated with silver nanoparticles. When a filter is placed inside a special case and water poured through, it removes almost all the bacteria, making it safe to drink.
In more creative mobile tech news: Kinsa consists of the thermometer -- which attaches to the headphone jack -- and an app that tells a user the local "health weather" as well as their temperature.
Until now, it was hard for geneticists to tell which parent or family line was the source of a particular genetic variant. The technique will enable improved risk assessment for diseases and refine organ matches for donors and recipients.
Researchers have designed a type of laser technique that is able to distinguish the bad -- specifically, the proteins responsible for Alzheimer's and similar diseases -- from the good. Simply locating them could make removing them much easier.
Oxford University researchers are currently testing the device, which captures images and puts them on transparent LED displays, on people who retain some ability to perceive light and motion.
Newly published in PLoS Computational Biology is a study describing new technology that safely delivers controlled anesthesia without requiring consistent human monitoring.
In research done on mice, a compound inside the venom of Chinese red-headed centipedes performed as well as, and in some cases even better than, morphine.
Diabetics may someday be able to test their blood sugar levels using a simple, painless laser device that registers glucose in skin cells.
A study claims that, compared to the current donation system, offering donors $10,000 for their kidney would improve health outcomes and, consequently, lower costs.
A protein used by the liver to metabolize belly fat is also used by the brain's memory center. More belly fat increases the chances that the liver will steal some protein from the brain in order to do its job.
Unlike a traditional pacemaker, which requires surgical insertion and involves hooking up lead wires, the Nanostim device is installed via a catheter and attaches directly to the heart muscle.
Philadelphia Children's Hospital is the first in the nation to remove supplements such as echinacea and coenzyme Q10 from its list of approved medications. One reason given is that they may cause harmful interactions with other drugs.
