The hagfisk returns at least 300 million years. The secret of surviving to these ubiquitous seabirds can be found in the rate and ability of pike making the product to perform birds. Internationally, the oldest fossils of these ubiquitous seabirds, found in Illinois, and contemporary researchers at the University of Illinois in Urbana-Champaign, are beginning to understand the secret of using the hagfisk this substance to taste his predatory animals.
"Hagfish are both wonderful and wonderful," Randy Ewoldt, a lecturer of medical science and engineers in Illinois, ran around, studying the hagfish for about a decade. "The reason they are wrong explains how they've survived this time."
Ewoldt, first author Gaurav Chaudhary, a PhD student at Ewoldt's laboratory, and Jean-Luc Thiffeault, a mathematician from the University of Wisconsin, have shared their findings on "Unraveling Hagfish Slime" in published a paper by Journal of the Royal Society Interface.
The fact that they are known for a number of years is known, but it was not until these decades that there was evidence of any economy with their sleep. To expire the evenings of some predator successes, confirm the suspicions as why the economy makes the pruning product.
"If the economists sleep this, they are doing a tremendously effective way of growing the amount of material they put into the water in a capacity of up to 10,000 to make the final cure," explained Ewoldt. "The voluminous rise is surprising and as much as I know something else in the nature or everything we as engineers have done."
Likewise, although there are a number of real world applications that are likely to be developed in the future with the hagfish's method, explain how much the economy has this material product, more curiosity investigation.
"We wanted to investigate the pike after the amazing research, how clear and interesting that thing is," Ewold said. "The interesting physics and the fact that there is no clear analogy became our motivation for trying to explain it."
The Royal Society Interface publishes research results that are at the interface of various sciences. In this case, the explanation of & # 39; s mysterious economy is & # 39; e crossing of physics, mathematics and biology present.
"The hagfish does not keep the same topology during expansion in the meantime, it really changes fundamentally when it turns and its ability increases," Ewoldt said. "The focus of this study was on this unique mechanism."
What the team discovered was that the hagfish guns, 100 times more than a human hair and initially as a string of yarn, can penetrate into a block of an eye through fluid. As a result, it can be from a size of 0.1 millimeter to 10 centimeters in length, or a water retention in a dimension of 10,000: 1.
The papers built on papers published last year from 10 to 10 years in conjunction with experimental biologists, including Doug Fudge, a teacher professor in Chapman's university and the keeper of some economists.
The team of Chaudhary, Ewoldt, and Thiffeault hypothesized that the liquor makes it the real consequence than it is a chemical explosion. The content of a file in & # 39; A fudge care created a model that used both math and physics to test the hypothesis and discover that the time and ability of the sleep enhancement were correlated to the viscosity and flow of & # 39; a surrounding velocity. In other words, if the sleep was put in still water, it would not be able to, but in the middle of a few attacks there would be enough flow for the sleep to develop.
By the way, assaulted at some economical conditions under different circumstances, his team could be improved with a model scenario. Another driving factor is probably that this process still has to be measured – that is, the colors in the cut, which can give you some resistance.
"In order to avoid the physiotherapy sum in the case of economics, we had to simplify our mathematical model and use some of the sensible values to do this," says Ewoldt. "One really powerful way to do this is to use regulation and use dimensional analysis to take and find complicated complications of all-matched relationships. The robustness is that it's not just one value of ownership, instead of a variety of things we could do by harming this math in a powerful way. "
In the end, under various circumstances, it concludes that this development is about 0.1 millimeters to about 10 centimeters in less than a few hundred milliseconds.
While the result of sludge is a solid, it is sufficient enough to take the form of its contour, so that it almost makes it into the eye in a goat of water. It is also strong enough and not sufficient enough to hold the stream of water.
In the future, Ewoldt wants to, a leading expert in & # 39; The study of rheology, and his team, further investigates hydraulic permeability and ultimately plays a part in the same-owned development materials.
"I would like to think more about the material design aspect," said Ewoldt. "We still haven't delayed how & # 39; t make you a material that swells it in water and puts things in a marine environment."
You can say that when it comes to economics, a creature that has survived for at least 300 million years, there are still more secrets to develop.
