This traditional portrait of Athanasius Kircher gives his age as 76. The engraver has emphasized the energy in Kircher’s inquiring eyes. A professor of eloquence in Rome added the flowery inscription: “The painter or poet would declare only in error: ‘This is the man.’ But the farthest Antipodes know his name and face.”

The discovery of the “pacemaker gene” could lead to new drug treatments to avoid heart attacks and disease, say experts.
A person’s heartbeat is controlled by electrical signals, which start in one central place – the heart’s pacemaker – and travel around the heart muscle.
And now, a team at Imperial College London have found the gene that controls those electrical signals and thus the rhythm of the heart.
The researchers claimed that the damage or mutations to the gene – known as SCN10A – increase the risk of heart disease.
The researchers believe that the finding could help them to understand how the body’s heartbeat is controlled and could ultimately help them come up with new treatments for heart rhythm disturbances.
