Expression of Empathy

Your Pain, My Brain
Feeling another person's pain. Why we react to the suffering of others.


When something hurts you, I feel it too. So suggests research by Sean Mackey, Ph.D., and his colleagues at Stanford University, who discovered that when people see others in pain, they show patterns of brain activation similar to patterns observed when they themselves are suffering.


Researchers scanned the brains of 14 subjects while they watched videos of people being injured in situations such as car crashes and sport events. The same subjects' brains were studied as researchers placed a painfully hot instrument on their arms. A comparison of the scans revealed that areas of the brain responsible for processing sensory and emotional aspects of pain were activated.


Mackey suggests this overlap represents a neurological expression of empathy, which may serve to bind people socially.

The Lost Fleet

In one night of thunder, fire and blood, the course of history was altered at the Bay of Aboukir.

In the famous Battle of the Nile, the British, under Vice Admiral Horatio Nelson, would utterly destroy Napoleon Bonaparte's fleet as it lay moored at the Bay of Aboukir, stranding the French general in Egypt and laying low his Pharaonic ambitions of ruling the Nile and wresting India from England.

Wormholes on Earth?

According to a group of mathematicians, it may be possible to create devices with internal tunnels that are invisible to detection by electromagnetic waves—wormholes, in a sense.


The scientists say that by custom designing the values of two parameters that describe electromagnetic (EM) materials, the electrical permittivity and magnetic permeability, around and inside a cylinder, a novel optical device could be produced.
