A Freaky Fly Experiment Offers a Clue"},"content":{"rendered":"

Pests are, well, pesky because they simply won\u2019t go away. And in a terrifying turn of events, scientists found that the fruit fly\u2014a super common kitchen pest\u2014adapts and survives under crushing hypergravity.<\/p>\n

According to a study on the findings, published recently in the Journal of Experimental Biology<\/a>, fruit flies initially show some bolstered activity under hypergravity<\/a>, or gravitational force several degrees stronger than what we\u2019re subjected to on Earth. At significantly higher levels, the flies did grow subdued. However, in both cases, the flies eventually returned to normal. In one experiment, they even mated and reproduced for 10 consecutive generations\u2014a biological feat that\u2019s somehow both impressive and horrifying.<\/p>\n

\u201cWe believe what we\u2019re seeing is that gravity feeds directly into the brain\u2019s decision-making around energy use and movement,\u201d Sushmita Arumugam Amogh, the study\u2019s first author and a neuroscience doctoral student at the University of California (UC), Riverside, said in a statement<\/a>. \u201cIt helps determine whether to act or conserve energy.\u201d<\/p>\n

One way or another <\/p>\n

When considering how gravity affects biology, researchers tend to investigate microgravity<\/a>\u2014the near-weightless conditions astronauts experience in space. That\u2019s also perhaps the most logical course of action, given the rich scientific literature on how microgravity influences astronaut health, such as significant shifts in their movement and balance systems before, during, and after extraterrestrial missions.<\/p>\n<\/p>\n

The team decided to investigate the other extreme, hypergravity, which hasn\u2019t been investigated nearly as much. The study wouldn\u2019t replicate what astronauts commonly experience under today\u2019s spaceflight capabilities. Still, the researchers believed that this approach could better illuminate how gravity\u2014an \u201cactive signal that influences how organisms move, how they use energy, and how they recover from stress\u201d\u2014governs energy and movement, they explained in the statement.<\/p>\n

Fruit fly merry-go-round <\/p>\n

For the experiment, the team released common fruit flies in a custom-built centrifuge to simulate hypergravity at 4G, 7G, 10G, and 13G (a single G is the amount of gravity we experience on Earth, so 4G equates to 4 times Earth gravity). Using infrared sensors, the researchers tracked changes in the flies\u2019 movements and tested their climbing behavior\u2014a measure of their tendency to move upward against gravity, the study found.<\/p>\n

\u201cThe centrifuge is like a merry-go-round,\u201d Arumugam Amogh said. \u201cThe faster you go, the more you feel pulled outward. That\u2019s hypergravity.\u201d<\/p>\n

The researchers ran several versions of the experiment.\u00a0In some tests, the team exposed fruit flies to each level of hypergravity for 24 hours and monitored how this affected their behavior for the rest of their lifespans (fruit flies typically live between 45 and 60 days<\/a>). Other tests had fruit flies consistently exposed to hypergravity for their entire lives.<\/p>\n

Under heavy gravity <\/p>\n

The results, as the team puts it, \u201cseemed counterintuitive.\u201d As the statement noted, the expectation is that crushing gravitational force would \u201cbreak down\u201d whatever biological system keeps a living organism functioning. Insofar as \u201cfunctional\u201d meant surviving and reproducing, the fruit flies didn\u2019t appear to be so bothered by hypergravity.<\/p>\n

At 4G, the flies became hyperactive. At increased levels of 7G, 10G, and 13G, the flies became less active. In both cases, the flies experienced hypergravity for 24 hours, explained Ysabel Giraldo, the study\u2019s co-author and an entomologist at UC Riverside. But as time passed, both groups returned to their normal states. In one intergenerational experiment, the flies thrived under hypergravity for 10 consecutive generations.<\/p>\n

To be clear, hypergravity most definitely affected fruit flies\u2019 biology. Hypergravity caused a brief spike in fat storage in flies, falling again as they became hyperactive. According to the study, it appears that smaller increases in gravity drive greater activity in animals, whereas the cost of moving increases as gravity grows stronger, leading to reduced activity.<\/p>\n

Flies will fly <\/p>\n

The results \u201ccomplicate a simple assumption: that extreme environments only cause damage,\u201d the researchers noted in the statement. Admittedly, fruit flies are not the best representatives of human behavior. Still, the research demonstrates the remarkable capacity of natural systems in bouncing back to normalcy after being pushed far from their original state.<\/p>\n

Likewise, the researchers noted in the paper that the adaptability of fruit flies\u2019 neuroendocrine system provides fascinating insight into how biology responds to different levels of gravity. Any information helps\u2014especially as humanity strives to expand its presence in space.<\/p>\n

\u201cI think our study is really timely,\u201d Giraldo said. \u201cThe link between gravity, physiology, and energy use will only become increasingly important to understand as space travel is poised to become more common in the future.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"Pests are, well, pesky because they simply won\u2019t go away.
