新闻来源:admin 发布时间:2018-09-17

Ever found yourself in a hazardous relationship in which your spouse makes your hair go white? Well, if the answer大发快三开奖结果’;s yes then you’;re not alone。 A new study provides new evidence that key aspects of the social environment of some animals significantly influence life span after researchers found that sexually frustrated fruit flies and “;haunted”; hermaphrodite nematodes died earlier than expected。

Environmental cues play pivotal rules in an organisms’; development *** health。 It’;s not only about the space and objects around an animal that influence it however, interactions with other members of the species also have an effect on longevity。  For instance, female fruit flies face a dramatic cut in life expectancy after mating since the male fruit fly’;s seminal fluid contains toxins。 Now, a group of researchers led by Scott Pletcher, a geneticist at the University of Michigan, Ann Arbor, fo*** that sexually frustrated fruit flies live a shorter life。

An unshared love

Pletcher and colleagues played a most cruel prank on male fruit flies。 The researchers genetically modified some male fruit flies to expel female pheromones that typically invite male for mating。 To normal flies’; surprise they found they couldn’;t mate  with these strange “;females”;。  This sexual frustration caused the males flies to lose fat, become stressed, and decrease in life span by 10%。

After dwelling deeper into the physiological processes sparked by the psychological sexual frustration, the researchers found that some neurons that signal the production of a certain protein which enable the flies to respond to rewards or mating were destroyed。 So, basically living in a delusional world was too much for the fruit life as it never got to have a piece (reward) of what it was***pecting (anticipation)。 Similar results were measured after female flies were modified to release male pheromones; this trickery caused female flies to also live shorter lives。
