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."

This 5-minute neck scan can spot dementia 10 years before it emerges

The results come from a 15-year study that used ultrasound scans to track blood vessels in middle-aged adults starting in 2002.

Mind & Brain
  • The study measured the stiffness of blood vessels in middle-aged patients over time.
  • Stiff blood vessels can lead to the destruction of delicate blood vessels in the brain, which can contribute to cognitive decline.
  • The scans could someday become a widely used tool to identify people at high risk of developing dementia and Alzheimer's.

How 'dark horses' flip the script of success and happiness

What defines a dark horse? The all-important decision to pursue fulfillment and excellence.

Big Think Books

When we first set the Dark Horse Project in motion, fulfillment was the last thing on our minds. We were hoping to uncover specific and possibly idiosyncratic study methods, learning techniques, and rehearsal regimes that dark horses used to attain excellence. Our training made us resistant to ambiguous variables that were difficult to quantify, and personal fulfillment seemed downright foggy. But our training also taught us never to ignore the evidence, no matter how much it violated our expectations.
