Who Knows What Lurks In The Mouths Of Men?
The sensor knows: Taiwanese researchers have created a prototype of an implantable device that may one day give dentists and others insights on patients' oral habits and hygiene.
What's the Latest Development?
Researchers at National Taiwan University managed to pack sensors onto a tiny circuit board, which they then implanted into a pair of dentures. On tests done with denture wearers, and using special machine learning software, they were able to distinguish jaw motions associated with different activities -- chewing, speaking, smoking, and the like -- with 94 percent accuracy. They plan to present their work at the International Symposium on Wearable Computers in September.
What's the Big Idea?
The prototype represents a first step toward being able to determine patients' oral habits in real time. The team's next steps include making the device even smaller so that it can fit into a cavity or crown, adding a microbattery -- the prototype was connected to an external power source -- and, if possible, adding Bluetooth to enable data transmission to a smartphone app. If they're successful, says Trevor Johnson of the UK's Faculty of General Dental Practice, "[t]his could have a number of uses in dentistry, for example as a research tool, for monitoring patients who clench or grind their teeth, and for assessing the impact of various dental interventions."

Upstreamism advocate Rishi Manchanda calls us to understand health not as a "personal responsibility" but a "common good."
- Upstreamism tasks health care professionals to combat unhealthy social and cultural influences that exist outside — or upstream — of medical facilities.
- Patients from low-income neighborhoods are most at risk of negative health impacts.
- Thankfully, health care professionals are not alone. Upstreamism is increasingly part of our cultural consciousness.
The Bajau people's nomadic lifestyle has given them remarkable adaptions, enabling them to stay underwater for unbelievable periods of time. Their lifestyle, however, is quickly disappearing.
- The Bajau people travel in small flotillas throughout the Phillipines, Malaysia, and Indonesia, hunting fish underwater for food.
- Over the years, practicing this lifestyle has given the Bajau unique adaptations to swimming underwater. Many find it straightforward to dive up to 13 minutes 200 feet below the surface of the ocean.
- Unfortunately, many disparate factors are erasing the traditional Bajau way of life.
Some evidence attributes a certain neurological phenomenon to a near death experience.
Time of death is considered when a person has gone into cardiac arrest. This is the cessation of the electrical impulse that drive the heartbeat. As a result, the heart locks up. The moment the heart stops is considered time of death. But does death overtake our mind immediately afterward or does it slowly creep in?
An innovation may lead to lifelike self-reproducing and evolving machines.
- Scientists at Cornell University devise a material with 3 key traits of life.
- The goal for the researchers is not to create life but lifelike machines.
- The researchers were able to program metabolism into the material's DNA.
