New Health Monitor Swims the Bloodstream
Stanford medical scientists have created a small wireless computer chip powered by magnetic currents that can navigate the body's veins while monitoring health and releasing drugs.
What's the Latest Development?
Medical scientists at Stanford have created a tiny computer chip capable of navigating the body's blood vessels while monitoring patient health and delivering drugs. While the device holds medical promise, it was a breakthrough in mathematics that allowed researchers to overcome previous barriers to powering the chip. Traditional batteries take up too much space, not to mention the problem of corrosion. By recalculating old equations and accounting for the body as an electricity insulator, magnetism became a suitable power source.
What's the Big Idea?
Minute wireless devices of this kind could usher in an era of telemedicine, completely transforming health care by enabling novel, and non-invasive, ways to monitor patient health and administer treatments. In the future, the chips could even "zap blood clots or remove plaque from sclerotic arteries." By using direct current, the device can zip through the bloodstream at a half-centimeter per second. Other devices, like heart probes, chemical sensors, cochlear implants and pacemakers, would remain stationary in the body.

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.
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.
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?
- A huge segment of America's population — the Baby Boom generation — is aging and will live longer than any American generation in history.
- The story we read about in the news? Their drain on social services like Social Security and Medicare.
- But increased longevity is a cause for celebration, says Ashton Applewhite, not doom and gloom.
