Imagine a computer that can think as fast as the human brain while using very little energy. That's the goal of scientists seeking to discover or develop materials that can send and process signals as easily as the brain's neurons and synapses.
WARWICK — A Superior Court judge on Monday struck evidence in two cases after finding that state troopers violated the alleged suspects’ rights by unconstitutionally converting routine traffic stops into narcotics investigations and warrantless searches. Judge Daniel A, Procaccini suppressed evidence in two cases involving out-of-state drivers of color traveling along a section of Route 95 identified by law enforcement as a drug-trafficking corridor.
