Think on this the next time you accidentally swallow a gulp of sea water.
We are witness to a scientific first. There have been many stars shot out of super-giant galaxies, but this is the first time we have seen a cluster of stars ejected from one. The reasons are still unknown, but never fear. Scientists are full of theories.
Researchers have developed a microbial fuel cell that can generate small but usable amounts of power from human saliva.
So, many in the scientific community believed that sharks have pretty much been an evolutionary static for millions of years, stalking our oceans practically unchanged by time. They seemed to be the pinnacle of apex predators, perfectly suited for their task at hand. But a new shark fossil was found in Arkansas earlier this week, that is looking to turn that theory on its head. This new find is already making waves in the paleontology community. Have a read for yourself. Here is the NPR link for the article for a layman’s terms story, If you prefer a more in depth read, here is the original link as published in the well-respected scientific journal Nature.
I wanted to write to you guys today and get your opinions on something a little contraversial - GMO’s or Genetically Modified Organisms.
First I suppose a definition is in order, as many people either don’t know or are confused about what a GMO actually is. According to Dictionary.com a GMO is simply a “genetically modified organism: an organism or microorganism whose genetic material has been altered by means of genetic engineering.” Now, to some that may seem like rocket science, and to some that may seem like a scary idea. The definition of “genetic engineering” is the key here, and is hotly debated. One side reserves the term for organisms whose genes have been altered by humans on the level of DNA, gene splicing and the such. Others are a little broader in the scope they assign to the term, allowing it to mean any organism that has been hybridized from its naturally found form. An example of this would be the domestic dog, or the cow.
This division is part of the problem for labeling GMO products for human consumption - what gets labeled? For instance, many people do not know that today’s version of corn (a simple staple food for many) has been hybridized for centuries. Obviously we did not have gene splicing back them, so that leaves selective breeding, and hybridization. Many believe that corn started off looking nothing like today’s version - the yellow juicy kernels in a nice neat package wrapped up on a cob. instead it more closely resembled a grass, a stalk or blade with pods of dull colored seeds at the end like the picture below.
The corn we see today is found nowhere on the planet in nature, it is strictly farmed. A similar story is that of bananas. They started off at a fraction of the size they are today, and through selective breeding, the banana we have today emerged. It is said that the original banana, the ancestor to our modern one, is now extinct.
This is all fine and great and many of you may be wondering what the big stink is today about GMO’s and their labeling. Well, if this is where GMO stopped, I suppose many would see there to be no reason to label them. However, some agricultural seed companies did not see fit to leave it at this selective breeding. Some companies have reworked the genetic material of a lot of today’s cash crops, to many different ends. Some varieties boast a greater harvest by yielding more fruit. Some offer a longer yield period. This means more money for the farmers, and thus more for the seed companies. Some take it a step further. Organic food is a huge hit in today’s world, and people are becoming more and more educated about where their food is coming from. This comes for good reason. Some farmers use chemicals to protect their crops from insects and other weeds that would smother them or lower their yield. Some of these chemicals are harmful or potentially harmful to us. Therein lies the dilemma. In the U.S., these products are not required to be labelled. To some, myself included, this is inappropriate at very least. Now, this ties into GMO in that some of these same companies are altering the genes so that some pesticides and other treatment chemicals are “baked in” to their DNA. The plants themselves start producing chemicals that are potentially harmful.
I am not against GMO as a whole. I think it is amazing that we have the knowledge and skill to be able to alter things on such a basic level. The scientist in me wonders what level it could go to. But, as with all sicentific discoveries and practices, where does it stop? Where do we draw the line? And does the company producing these bear a responsibility to the consumer to inform us of what products that we consume are or are not GMO’s and if so what modifications were made? I think so. What are your thoughts? Should we even allow GMO’s? Should we allow but regulate? Or just label? Or do nothing at all and let the companies regulate the products themselves? Chime in on the comments below!
Diabetes has become one of the fastest growing health issue around the world. In the United States alone 25.8 million people have been diagnosed with diabetes, which is 8.3% of the population.
There are many functions of the pancreas, but the lack of insulin production is the main reason for developing diabetes.
Biomedical Engineers have been so successful in developing many artificial organs, like the AbioCoe Artificial Heart, which was implanted in a man who suffered from heart failure. Also, Bio-Artificial Liver, which was names the invention of the year in 2001, but there has been many failed attempts at developing an artificial pancreas. There has been complication, but mainly rejection by the immune system. I would like to be able to help develop such a device that would impact many lives.
One of the companies that I would like to work for after graduation is the International Biomedical Engineering Technologies (IBE Tech). It is a company founding in 1998, in Cairo, Egypt. Growing up in Egypt, I understand the importance of a company that develops cutting edge technology in the region. One of their main goals is to make high-tech medical equipment available, in the Middle East region and in similar less fortunate countries around the world, at low cost.
The DIGISON-Q is the company’s newest product and one of it’s kind in the region.
If I could make any inventions, I would make environment suits! For example:
A suit that could keep a human safe in the depths of the ocean while still maintaining all mobility. I found this really cool illustration on google images of what I might want it to look like
In real life, atmospheric dive suits look like this:
And this suit can only reach 700m below the surface.
The average ocean depth is 4264m.
A suit with big wings and pressure control so that people could fly places.
This is a jet suit! Apparently it already exists but I’m not sure how well it works since it hasn’t been commercialized.
Looks like a low-budget 80s super hero costume! But pretty cool!
The closest commercialized thing we have are wingsuits:
These suits were modeled after flying squirrels and neither actually fly, but the wingsuit can glide up to 22 miles!
I think making an anti-gravity device would be cool, too! So we could fly around like Kat in Gravity Rush~
Unfortunately, there is nothing I know of that can affect gravity on earth in isolated locations. It would be pretty cool if there was, though!
These things seem unrealistic, but when you think about how far technology has advanced, maybe these things aren’t as far off as you would think. It’s also fun to brainstorm designs like this because while the concept is unrealistic, you still have to think about real world physics that might make it so.
A heavy, clunky dive suit is necessary to protect humans from pressure at deep sea levels.
When thinking about flight or gliding suits, you have to take into account TONS of physics principles like air resistance, force of gravity, strain on the human, etc.
Brainstorming and curiosity are key to progression, so no matter how crazy the idea, there is always something to work for!
How I balance my hectic, crazy, and challenging engineering major coursework and socializing is by cloning myself. One would do the homework and one would hang out with my friends, and I, myself would rest for 16 hours.
And that guys is how I balance my social life and school life. (And Yes, I have the power to clone).
I separate my engineering life and social life by doing study groups with my friends from my classes. Also, I ask for help from them. That is a very good way to socialize in college. Me and my friends, we would go somewhere to eat and talk about class or any other subject. Don’t be afraid to ask for help. There is nothing wrong with getting help.
See you next time
These are some cool places to hang around at the University of Memphis.
One of these places is the UC.
The University Center is basically just cool place to hang out, socialize, meet new people, eat, organize events, attend events, and things of that nature.
These are places within the UC to hang out:
Those were near the entrance.
These pictures are from the Commuter Student Association, which is an organization celebrating and focusing on students who do not live on-campus.
Its also a good place to hang out.
These pictures are from the Tech Hub, which is a big computer lab, where you can chill out, study individually or with a group, or just hang out.
Next is the Alumni Lounge, a place where students come and hang out. And for those of you who are anime watchers or video game players. This is the place for you! This is like the hangout spot for them. You will find students who are always seen playing card games, discussing or watching anime, or talking about video games.
This is from one of the restaurants in the UC, Tiger Dining.
And these are just around the UC.
These pictures are from Jones Hall. It includes the Tiger Den, which is a buffet restaurant and a very good place to eat, hang out, and socialize. And it also includes Chick-fil-A and subway.
Here are pictures from Dunn Hall. These are pictures from the lounge room, where you can eat and hang out or study. BTW, Dunn Hall is where the Department of Computer Science and the Math Department is stationed in.
These pictures are from the FIT(FedEx Institute of Technology, where I used to work) also a good place to hang out and study.
These pictures are from the library (I know that sounds boring, but it is actually all right). A good place to chill out and have study groups. The library has numerous study rooms so you and your group or you yourself wants to study or review over material.
This is from South Hall, the boy’s dorm. Me and my friend played video games here once.
These pictures are from the Student Recreation and Fitness Center.
Yes, they have a spa and sauna.
So those are the cool places to hang around at the University of Memphis.
