For years this phenomenon remained a mystery. Reporting in the June 10 issue of Science, neuroscientists at the Johns Hopkins University School of Medicine have discovered that a light-capturing pigment molecule in photoreceptors can be triggered by heat, as well, giving rise to these false alarms.

"For 20 years, researchers have reported a potential link between gum disease and atherosclerotic heart disease from hardening of the arteries or stroke. "The message sent out by some in health-care professions, that heart attack and stroke are directly linked to gum disease, can distort the facts, alarm patients and perhaps shift the focus on prevention away from well-known risk factors for these diseases," said Dr. Peter Lockhart, a professor and chair of oral medicine at the Carolinas Medical Center in Charlotte, N.C. Lockhart wrote the heart group's new position statement in the journal Circulation. The statement was prepared after a three-year analysis of about 600 studies by an expert panel led by a dentist and a cardiologist."

"Dr Zbinden said that while the discovery of the bacterium is no cause for alarm, it is important that it is recognised and the risk is quantified. "This bacterium seems to have a natural potential to cause severe disease and so it's important that clinicians and microbiologists are aware of it"
