How Fast Is America Sinking?
From hard data about China's economic prowess to cultural markers like Sesame Street's new impoverished puppet, it sure seems like the U.S. is losing ground, and fast.
What's the Latest Development?
While the American economy is mired in unemployment and its global goodwill stymied by two foreign wars, the superpower is feeling more humbled than ever. "Not a day goes by without a classic example, from the poverty-stricken new muppet on Sesame Street who doesn't have enough to eat to the supposed cocaine slump on Wall Street and the new government initiative to attract Chinese shoppers here." Still, the recent Republican debates have spared no praise when it comes to recognizing America's greatness.
What's the Big Idea?
If political leadership is any indication of where the U.S. may be going next, the signs are not encouraging. "There's much that ails America today, from schools that stink to collapsing infrastructure and a bloated financial system nowhere near finished dealing with the results of the burst housing bubble. But the bigger problem may be this: a political system that rewards bloviating over American greatness but not those whose hard work or big ideas might ensure Americans actually still have something to crow about."
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.
