Linking Icequakes and Earthquakes

How much do you know about icequakes? The terminology is not nearly as common to hear as ‘earthquakes,’ but in fact the two have some undeniable links. In its most basic form, icequakes or frost quakes are the breaking up on large frozen masses like ice sheets, glaciers and the like. So what does this all mean and how are these things linked? Read on to learn more!

Recent studies have linked the high impact 2010 Chilean earthquakes to noticeable changes in Antarctica in the form of these ice quakes. What makes the link between this case of earthquakes and subsequent icequakes is the 3,000 mile between the two areas. Not Studies since the 8.8 earthquake in 2010 have revealed that the ice in Antarctica is vulnerable to seismic waves even originating from remote locations.

This ripple effect can be explained to young learners through basic cause and affect principles. Learning about links like these can help them understand how science and the environment work through interlocking systems. Ultimately when one major even like high magnitude earth quakes occur, they can still have repercussions thousands of miles away.

Understanding the Origin of Stars

Stars light up the night sky on a daily basis and are for both kids and adults tiny twinkling specimens that are full of mystery. After all how much do you little ones really know about where stars come from and how they illuminate the skies? Scientific study has revealed stars to be collections of atoms floating in space that form carbon, oxygen, and hydrogen. Under the right conditions stars and even small planets form as a result.

To dive deeper into the study of stars and their formation, NASA has just recently sent a flight into a star nursery to properly observe the inner workings of star formations. This will give researchers and scientists the opportunity to see the step by step process of how a star comes to be. The payload sent into space is known as the Colorado High-resolution Echelle Stellar Spectrograph, or CHESS.

This all new technology is allowing us to record details such as the timeline breakdown for the forming of the clouds in space. Sending the CHESS into space also allows NASA to test for sending future satellites into space.

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!

Avoiding a Sticky Situation

The tentacles of an octopus will stick to just about anything—well, almost anything. These suckers usually don’t suction onto to the octopus itself, allowing this brilliant and flexible creature to avoid getting tangled up in its own arms. Researchers are studying this undersea creature’s talent of escaping a twisted situation with hopes that what they find can be strategically used in bio-inspired robot design.

Scientists observed that the reason why the octopus doesn’t end up in a knotted mess, is because of the animal’s great intelligence that demonstrates “self-avoidance.” This ability is actually a reflex, that can be turned on and off as the cephalopod pleases. A sort of chemical signal in the skin is activated that controls the suckers from grabbing onto their skin.

Researchers aim to support the development of a new kind of “soft robot” in the shape of an octopus arm, perfect for using in human surgeries. These types of robots would be able to reshape their forms, making it easy to maneuver around unfamiliar obstacles inside the human body!

Science Fair Projects

  3. The cap from a milk jug
  4. A pie plate (9 to 12 inches in diameter)

Steps:

  • Fill your pie dish with water.
  • Place the cap from a milk jug onto the water to float. Center the float.
  • Straighten the steel paper clip and turn it into a magnet—Take your magnet and stroke it along the straightened paper clip around 15 times.
  • Place the magnetized paper clip onto the float and watch as your paperclip will slowly point North!

With hands-on experiments like these, kids will have a blast when discovering that they are fully capable of carrying out their own scientific experiment! For more inspiration on science fair projects, follow us on Pinterest and share with us some of your favorite discoveries!

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.

Flying Snakes

Snakes—scaly, slithering, hissing reptiles that fly? If you disagree, don’t let their lack of wings fool you into believing they can’t! There are some snakes that can glide through the air as far as 100 feet! How do they do it with out wings? Scientists are interested in their ability to glide as it may answer mechanical and aerospace questions.

There are five recognized species of flying snakes that are found in western India and Indonesia. These snakes are thought to be strictly tree dwellers and are rarely seen coming down from their comfy canopy homes. Scientists aren’t quite sure why or how often flying snakes fly, but it’s likely they do to move from tree to tree with out having to slither down just to climb back up another one or to escape predators and even hunt for food.

These flying snakes have the ability to rotate their ribs which allow them to flatten their bodies. The term “flying” isn’t necessarily what they do since they don’t gain altitude, but instead they are able to glide and they are very good at it. From high up on tree branches, flying snakes can fling themselves out of the tree then flattening their bodies into a concave C shape to trap air beneath them to seemingly slither through the air!

New research is investigating how the snake’s technique of gliding works and if their findings can be applied to mechanical problems with identifying the best air flow for smaller wind turbines.
