The brain is equipped with barriers designed to keep out dangerous pathogens. Researchers have now found a novel way to circumvent the brain’s natural defenses when they’re counterproductive.

Biologists have explained for the first time why having a good night’s sleep really could prepare us for the rigors of the day ahead.
Despite reports that global emissions of the potent greenhouse gas were almost eliminated in 2017, an international team of scientists has found atmospheric levels growing at record values.
For as many as one in three people, life events or situations that pose no real danger can spark a disabling fear, a hallmark of anxiety and stress-related disorders. Researchers at Yale University and Weill Cornell Medicine report on a novel way that could help combat such anxiety. In humans and in mice, a ‘safety signal’ — a symbol or a sound that is never associated with adverse events — can relieve anxiety through an entirely different brain network than that activated by existing behavioral therapy.
