A team of researchers at the University of Michigan has found that worms change when exposed to their dead counterparts, their fertility and life change.
According to RCO News Agency, Many insects, such as bees and ants, instinctively remove the dead members from the hive, apparently to keep the nest clean from any potential pathogenic agent.
Group research at the University of Michigan describes a similar case among C. Elegans.
They have discovered that the presence of dead members among the worms has deep behavioral and physiological effects, causing creams to reproduce faster and shorten their lives.
“We felt that this is a completely unique opportunity to begin examining a mechanism that enables Elgan Carm to identify a dead counterpart and then guide what they respond,” says
Elegance worms, because of their relatively short life span, are an ideal model for studying life and extending life.
Their recent study came from a observation showing that creams in the wake of their deceased counterparts were as far as possible.
The group asked himself how creams that do not have eyes recognize that their fellow humans are dead and whether a global death signal may be published by the corpses.
To test this, they inserted cream or liquid bodies from the decomposed cells of the cream into different nutritional areas on a container.
They observed that Elegance worms showed a severe behavior for both.
In addition, they found that understanding of death results in a decrease in fitness in exposed worms and a short -term increase in their eggs.
They then systematically tested sensory neurons to determine which one is essential to understanding death.
They found two neurons responding to olfactory information and found that the worms could basically smell of death.
In particular, the group identified the two metabolites, commonly found inside the cells, which were signs of death for the Elgan Cream.
“The neurons we identified are involved in behavioral responses to a variety of environmental signs,” says Trotman.
We have now found that they also recognize a few intracellular metabolites that are not usually found in the environment. If those symptoms are around, it shows that a dead cell has been opened and a problem has happened.
He points to the recent finding in humans that cells that develop apoptosis (cell death) release metabolites that lead to transcription changes in adjacent tissues.
How to diagnose this signal ultimately leads to change of health and behavior requires further research.
