The feminine locust digs deep into the bottom with a view to lay her eggs in a secure place. In doing this, she is ready to lengthen her stomach, together with the nervous system, to 2 to 3 instances its dimension – similar to a film superhero.

A brand new Tel Aviv College (TAU) research has discovered that the feminine locust’s central nervous system has elastic properties, permitting her to stretch as much as two or thrice her authentic size when laying her eggs within the floor with out inflicting any irreparable injury.

“We’re not conscious of the same skill in nearly any dwelling creature,” say the researchers. “Nerves within the human nervous system, for instance, can stretch solely as much as 30 p.c with out tearing or being completely broken. Sooner or later, these findings might contribute to new developments in regenerative medication as a foundation for nerve restoration and the event of artificial tissues.”

The research was carried out by a workforce of researchers led by Dr. Bat-El Pinchasik of the Faculty of Mechanical Engineering in TAU’s Fleischman School of Engineering and Professor Amir Ayali of the Faculty of Zoology in TAU’s George S. Smart School of Life Sciences.

Additionally taking part within the research had been Dr. Rakesh Das from the Faculty of Mechanical Engineering, Dr. Moshe Guershon from the Faculty of Zoology, and Professor Eran Perlson and Amjd Ibraheem from the Division of Physiology and Pharmacology of TAU’s Sackler School of Drugs. The analysis was revealed in Science.

“When the feminine locust is able to lay her eggs, she digs a gap within the floor that can provide them safety and optimum situations for hatching,” Dr. Pinchasik explains.

“For this goal, she is provided with a singular digging equipment, consisting of two pairs of digging valves that are positioned on the tip of the stomach, on both aspect of the ovipositor, a tube-like organ used for laying eggs. As she digs, the feminine extends her physique till sensors positioned alongside its size sign that she has reached an acceptable level for depositing her eggs.

“Thus, an grownup feminine, whose physique size is about 4 to 5 centimeters, might, for the aim of laying her eggs, stretch her physique to a size of 10-15 centimeters, then rapidly return to her regular size, after which lengthen once more for the following egg-laying.”

“The superpower of the locust is sort of one thing out of science fiction,” Professor Ayali provides. “There are solely two different recognized examples in nature of the same phenomenon: the tongue of the sperm whale, and a sure sort of sea snail whose nervous techniques are in a position to lengthen considerably resulting from an accordion-like mechanism they’ve. We sought to determine the biomechanical mechanism that offers the feminine locust its great skill.”

Within the research, the researchers eliminated the central nervous techniques from feminine locusts and positioned them in a liquid simulating their pure atmosphere beneath physiological situations much like these contained in the physique. Utilizing extremely delicate measuring devices, they measured the forces wanted to increase the nervous system.

“Opposite to earlier hypotheses and examples we’re accustomed to, we didn’t discover any accordion-like mechanism,” Dr. Pinchasik says. “We found that the nervous system of the feminine locust has elastic properties which allow it to elongate after which return by itself to its authentic state, prepared for reuse, with none injury induced to the tissue. This discovering is sort of incomprehensible from a biomechanical and morphological perspective.”

“In our research, we discovered that the central nervous system of the grownup feminine locust is elastic and is ready to stretch two to 3 instances its authentic size after which return to it, with none injury being induced,” Professor Ayali concludes. “That is an unimaginable skill that we don’t know of in every other animal. In additional research, we’ll examine the matter in depth, with the goal of figuring out the particular mechanism that allows this distinctive function. We hope that sooner or later our findings will assist to develop artificial tissues with a excessive degree of flexibility, and to revive nerves in regenerative medication therapies.”
