Human Aggressive Behavior Could Be Chemically Induced

You may not be responsible for aggressive behavior. New research shows that it could be caused by a chemical that strongly influences what you do, a chemical that you are not aware of.

The Longfin squid lays its eggs each year in warm shallow water. Eggs are coated with a protein pheromone. When a male squid gets close to the eggs the chemical is absorbed and the sea creature attacks any other male squid in close proximity.

It was thought that the cause of human aggression was in the brain which interacts with the body's physiological structure. This is now brought into question. Squid are complex, like humans. A similar protein pheromone is found in human seminal fluid.

A New Discovery on Immunity by Australian Scientists

Acclaim is given to two Australian scientists, Walter and Eliza Hall, who have changed ideas about the memory of the immune system. B cells make antibodies to fight infection. These cells do not die after doing their job and this is not the normal run of things.

A pro-survival proteins is responsible for the cells' continuing existence. It has been proven that the Mcl-1 protein does this, not the Bcl-xL protein as was accepted in the past. Earlier this year tests blocked the activity of Bcl-xL which showed that Mcl-1 stopped apoptosis - death.

Cancer cells survive due to Mcl-1, so there are new possibilities for cancer research. It could also have repercussion for future treatment of the resistance response in organ transplant patients.
