'Living' Micro-Robot Will Detect Human Disease
A robot designed to mimic the biology of a lamprey may soon be swimming through your body, with the capacity to detect the presence of diseases better than your immune system.
What's the Latest Development?
British and American scientists are working to build a tiny robot that mimics the biology of a sea lamprey, found mainly in the Atlantic Ocean. Dubbed 'Cyberplasm', scientist want the machine to "have an electronic nervous system and 'eye' and 'nose' sensors derived from mammalian cells, as well as artificial muscles that use glucose as an energy source to propel it." Initially, the size of the robot will be less than 1cm in length but scientists want to reduce the size to less than 1mm, perhaps making it nano-sized as technology advances.
What's the Big Idea?
Biomimicry, though complex, would produce machines as well suited to their environment as animals—no small achievement when it comes to understanding our world. "Nothing matches a living creature’s natural ability to see and smell its environment and therefore to collect data on what’s going on around it," said bioengineer Dr. Daniel Frankel of Newcastle University, who is leading the UK-based work. Applications for the technology include swimming through the body to detect disease or advancing prostheses by developing artificial muscle tissue which responds realistically to its environment.

What can 3D printing do for medicine? The "sky is the limit," says Northwell Health researcher Dr. Todd Goldstein.
- Medical professionals are currently using 3D printers to create prosthetics and patient-specific organ models that doctors can use to prepare for surgery.
- Eventually, scientists hope to print patient-specific organs that can be transplanted safely into the human body.
- Northwell Health, New York State's largest health care provider, is pioneering 3D printing in medicine in three key ways.
Neuroscience is working to conquer some of the human body's cruelest conditions: Paralysis, brain disease, and schizophrenia.
- Neuroscience and engineering are uniting in mind-blowing ways that will drastically improve the quality of life for people with conditions like epilepsy, paralysis or schizophrenia.
- Researchers have developed a brain-computer interface the size of a baby aspirin that can restore mobility to people with paralysis or amputated limbs. It rewires neural messages from the brain's motor cortex to a robotic arm, or reroutes it to the person's own muscles.
- Deep brain stimulation is another wonder of neuroscience that can effectively manage brain conditions like epilepsy, Parkinson's, and may one day mitigate schizophrenia so people can live normal, independent lives.
As Game of Thrones ends, a revealing resolution to its perplexing geography.
- The fantasy world of Game of Thrones was inspired by real places and events.
- But the map of Westeros is a good example of the perplexing relation between fantasy and reality.
- Like Britain, it has a Wall in the North, but the map only really clicks into place if you add Ireland.
A recent study gives new meaning to the saying "fake it 'til you make it."
- The study involves four experiments that measured individuals' socioeconomic status, overconfidence and actual performance.
- Results consistently showed that high-class people tend to overestimate their abilities.
- However, this overconfidence was misinterpreted as genuine competence in one study, suggesting overestimating your abilities can have social advantages.
