Alarm pheromones are substances that send danger signals to different parts of the brain. When these signals are perceived by other pheromones of the same class, they can act as cues that alert humans or animals about a potential ...
Food is essential for life—a daily source of calories and comfort. But for the more than 3 million adults in the United States that suffer from Inflammatory Bowel Disease, or IBD, it is also a daily source of pain and discomfort.
