The Fly on the Wall

It is easy to dismiss their presence and want to overlook the pesky circling of fruit flies, but these little organisms are actually more complex than they might look. In fact, researchers have recently been studying these bugs to come to a better understanding of their thought process. A team of neuroscientists have observed fluctuations in the time they take to process information before acting on a decision to hypothesize that they actually take a longer amount of time to make what scientists have determined as more difficult decisions.

Are these tiny pests of a heightened intelligence than we might have initially thought? That is exactly the question that researchers are hoping to answer as they delve further into their studies. So how exactly are they testing the flies’ decision making skills? Like with any experiment they create a controlled environment testing certain variable options. More specifically they encase the flies in a narrow compartment, pitting two concentrated scents on both ends of a spectrum to see where the flies end up.

As for measuring the difficulty of the decision, scientists varied the distance between the concentrated scents. The closer the concentrations were, the longer the flies took to differentiate and identify to which area they preferred to fly. The consistency of the results, allowed them to conclude that there are links in the system which humans use to make decisions and that of these flies, which is all connected to the FoxP gene. Needless to say, there is more to these flies than meets the eye!

Impressive Strength: The Peacock Mantis Shrimp

The ocean dwelling Peacock Mantis Shrimp is tougher than its name implies. Do not let this pretty little guy fool you—this creature’s front appendages can strike with an underwater acceleration that equates to the same velocity of a speeding bullet from 22-calibur rifle! So why are researchers willing to go face to face with such a menacing little crustacean? Researchers have designed a structure for composite materials that can resist impacts tougher than airplane standard materials. All of this is inspired by the stomatopod’s impressive strength that seems out of this world!

With raptorial appendages that fold under its body, similar to that of a Praying Mantis, the Peacock Mantis Shrimp can deliver a hard hitting blow. They can wield their fist-like clubs to strike prey with great force at speeds up to 50 miles per hour in milliseconds—we can blink and miss this shrimp’s punch! Their appendages move so fast that the water that surrounds these limbs start to boil and create cavitation bubbles. When these bubbles collapse, they produce an underwater shock wave that is strong enough to affect their prey even if the Mantis Shrimp misses its target.

What is most impressive about this species is that is can punch up to 50,000 times with out damaging its clubs before molting. This unbelievable strength of such a tiny animal is what makes them one of the more interesting species to scientists in the animal kingdom. Studying the Mantis Shrimp’s fist-like clubs, will allow researchers to identify the key components to its structure and applying that knowledge to creating improvements with everyday objects, including advanced body armor for combat troops.
