With the discovery in the late 1980s that bacteria were involved in causing peptic ulcers, many doctors dropped the notion that stress causes ulcers and declared them merely an infectious disease. Not so, says an expert panel convened this month by the Academ...... plants remain a vast, untappedresource for future discovery of new natural compounds, which have potentialutility in multiple industries.
