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.

It's up to us humans to re-humanize our world. An economy that prioritizes growth and profits over humanity has led to digital platforms that "strip the topsoil" of human behavior, whole industries, and the planet, giving less and less back. And only we can save us.
- It's an all-hands-on-deck moment in the arc of civilization.
- Everyone has a choice: Do you want to try to earn enough money to insulate yourself from the world you're creating— or do you want to make the world a place you don't have to insulate yourself from?
A growing body of research shows promising signs that the keto diet might be able to improve mental health.
- The keto diet is known to be an effective tool for weight loss, however its effects on mental health remain largely unclear.
- Recent studies suggests that the keto diet might be an effective tool for treating depression, and clearing up so-called "brain fog," though scientists caution more research is necessary before it can be recommended as a treatment.
- Any experiments with the keto diet are best done in conjunction with a doctor, considering some people face problems when transitioning to the low-carb diet.
Upload your mind? Here's a reality check on the Singularity.
- Though computer engineers claim to know what human consciousness is, many neuroscientists say that we're nowhere close to understanding what it is, or its source.
- Scientists are currently trying to upload human minds to silicon chips, or re-create consciousness with algorithms, but this may be hubristic because we still know so little about what it means to be human.
- Is transhumanism a journey forward or an escape from reality?
