Yes, there was a time when meditation and yoga were scorned upon as "hippie" or "new age" fads. But over and over again scientific studies have shown that meditation improves everything from heart health to study habits to forgiveness! Why wouldn't everyone want to learn meditation as a life skill? It would cut down the cost of medications, hospitalizations, surgeries, therapy needs, medical costs... Heck, everyone would be healthy! And maybe even nicer to each other.
.... TIAs aren't called mini strokes for nothing. The most common cause of TIA is the very same as the most common cause of stroke: blood clots blocking blood flow to the brain. The difference is that TIAs usually resolve within minutes or a few hours. The classification of the incident is all a matter of how long the blockage lasts; if the disturbance doesn't clear up within 24 hours, you've had a stroke, not a TIA.
The large helmet is the ExAblate 4000, a magnetic resonance guided high-intensity focused ultrasound (HIFU) device, by Israel's Insightec. ExAblate 4000 has been tested successfully to isolate and destroy the smallest of tumors in the brain, without affecting the surrounding tissues or bones. Now, researchers are looking at the technology to do the same with blood clots that can lead to stroke.
