Winged Wednesday – Not A Fruit

The kiwi is a flightless, endangered bird that is native to New Zealand. It has tiny wings that are useless for flight. However, the kiwi has a keen sense of smell and the ability to run very fast. It has feathers that are almost hair-like, and its huge eggs can weigh up to half of its own body weight.

This fuzzy bird is not to be confused with the fuzzy fruit.

Death Is In Our Own Hands

Take a look around you. What do you see? Odds are, there is bacteria on it. Bacteria can live anywhere, including soil, the ocean, inside the human body, and many more places that you would not expect. Bacteria can survive in so many different kinds of environments, and there are more than 10 times as many cells of bacteria as there are human cells in the human body. It maybe essential to human life, but it comes with consequences- which could be sitting right in your hands.

Wolves in a Dire Situation

As with every warm-blooded American with cable TV and HBO, I love Game of Thrones and the fantasy world it occupies.  In the skies of Winterfell in northern Westeros, banners displaying the Sigil of House Stark wave gallantly. The Starks are symbolized by the dire wolf, the legendary beast with metal jaws, razor sharp claws and incomprehensible strength. In the show, each Stark child receives a rare Dire Wolf pup and raise them to be game changing weapons on the battlefield and loyal companions. All of this is fun but what happened to the real dire wolf, what factors lead to its extinction 9000 years ago?

To truly understand the dire wolf, it is necessary to learn more about their composition and social structure. Standing at three feet tall and 150 lbs., the dire wolf or Canis dirus was an apex predator in during the Pleistocene era, with its only true competitor in size and strength being the saber-toothed cat. In many ways the dire wolf is an extremely large grey wolf except for its larger, more muscular frame and head. Very similar to the grey wolf, dire wolves hunted in packs, preying on larger game such as moose where the former preferred smaller prey This observation is heavily supported by the number of dire wolf fossils found in concentrated areas; one said example is the La Brea Tar Pits where more than 2000 dire wolf skeletons have been unearthed Evansville. Dire wolves evolved in North America and lived in all environments found on the continent.

Polo Wars: Attack of the Clones

Clones: Many people when they hear the word think of Star Wars and the clones in the prequels. The clones in polo are a little different. As the clones in polo are fighting it is not a intergalactic war that is being fought to keep order in the republic, but instead these horses are just competing in the game of polo, however they still are clones.

Armadill-Dumbfounded: The History and Migration of The Nine-Banded Armadillo

Unfortunately, unless you go deliberately looking for one, odds are you will see one as roadkill, mostly on or by the highway. But what has caused these Armadillos to migrate to other states, and is what the history of these intriguing mammals?

Genes and Behavior: Is It In Our Nature?

A while ago, in Psychology class, our teacher’s daily lecture was on the classic psychological debate of Nature versus Nurture.  Do our genes impact our personality or are we an Aristotelian tabula rasa, or blank slate?  While a connection could be seen inherently through this psychological concept’s usage of biological premises, a connection was easily seen between Psychology and Biology after my teacher displayed a Punnett Square, a common sight in genetics as a way to explain the transfer of genotypes from parents to offspring.  As I recalled previous lessons from Freshman year on genetics, I couldn’t help but contemplate whether or not the theory had any validity.

Dr. Michael Kraus, assistant professor of Organizational Behavior at Yale, says it’s complicated.  Historically, he said, psychological studies would focus on twins, and compare self-reports from fraternal twins, those of which share around 50% of the genes, and identical twins, who share 100% of their genes.  In these studies, they found that the amount of variation in personality that is explained by genes, or heritability, was around 46% for identical twins, and around 23% for fraternal twins, showing a very clear suggestion that genetic influences had a noticeable impact on personality.  The problem is finding what genes specifically impact factors like personality, preferences, intelligence, or physical characteristics.

I’ve Lost My Contacts…Literally

One of the distinguishing characteristics between our Generation Z and the previous generations is the use of technology in our daily lives. It seems to be increasingly likely that teenagers are increasingly reliant on our cellular devices, to the point that it could be detrimental to our health. Multiple studies have shown that reliance on cellular devices can cause damage, but do we know exactly how harmful our iPhones and Androids, or iPads might be at night?
