Southeast Asia Underwater by: Mikayla Flanz


      Global warming. A gradual increase in the overall temperature of the Earth's atmosphere. It's a term kids from the past few generations have grown up with, but has now evolved into "climate change". The same meaning as global warming, only including the monumental consequences that come with it.

Up until the past few years, as a global community we have yet to reap the effects of climate change, but now that we have; hurricanes, temperatures, sea levels, and many other events have sent us spiraling. But up until now, there has never been a real threat to our ways of life.

     According to science correspondent, Josh Gabbatiss's article from British newspaper, The Independent, as opposed to the inhabitants of Southeast Asian and Pacific Islands getting the next century to keep their native lands, new research published in the journal, Science Advances proclaims that the once promised one hundred years are now diminished to a few more decades. 

Since the Industrial Revolution, more and more of the green house gases such as, carbon dioxide and methane have been released, overall warming our planet. Although this "warming" has only come to about a two degree global increase, that change melted enough of the ice caps for there to already be devastating floods throughout these islands. The constant rising sea levels exert more water onto the low lying land, here the sea water is able to leach into the soil, spill into freshwater supplies, and decimate infrastructure and farm land. 

    Narrowing in on the Marshall Islands of the South Pacific, Science Advances illustrates the 70,000 natives of these chains of islands, where due to climate change and rising sea levels they will lose access to freshwater supplies, causing their farming industry to collapse, leaving a good portion of these inhabitants with little to no income or food. Along with the fact that, the rushing flood waters will sit in the dry walls of these houses for days at a time before clearing out and drying, therefore leaving mold in it's place. However, the authors also find that these issues will soon extend to neighboring islands such as the Maldives, Hawaii, and Seychelles, driving hundreds of thousands of people from their ancestral homes.

This is definitely the most selfish and least important reason to want the islands to stay right where they are, BUT... I have always wanted to travel to these places. These destinations are stunning, the landscape, the sites, the culture, to experience it all would be extraordinary. Stepping away from my traveling fantasies, there are more important matters...

Anyway, as someone who has always dreamed of traveling the globe all their life, to now see the world being picked apart and slowly demolished is devastating, but to the people living this out and losing the only home they have ever known must be like walking through their own never ending nightmare. 70,000 people. And that is just one chain of islands, what about the more densely populated Maldives or state of Hawaii. Where are all these people going to go? What are they going to do? Some of these people know nothing outside of their island chains, are they supposed to simply adapt from thousands of years of tradition overnight? 

Not to point fingers, but those who think climate change "doesn't exist" or is a "natural occurrence" are going to be very sorry some day, and that day may be coming soon. Even though this is happening thousands of miles away, across oceans, on a different continent, who is to say this can never happen to our coasts. Already, climate change is mauling our southern coasts, nothing permanent yet, but nothing is impossible, these people native to these Pacific islands probably thought that they would die in their home, as would their children, as had their parents, and relatives before them, all before their world was torn apart.


As a global superpower, we can not stand idly by while this is happening, sure it has not directly effected us yet, but eventually it will. So what if we have to give up certain things like oil and coal, and invest for a future in eco-friendly power systems, hundred of thousands of people will have to give up their land by the middle of the century. Maybe it might be too late to save some of the islands, but do we really want to see this underwater and abandoned? Gone?

Who really wants to see this gone?

New Implant for Rats Gives a Good Indicator for the Future of Electrical Therapy- Daniel Devine

Pulses of electrical stimulation help heal injured nerves, research is displayed that shows a possible method of healing for these peripheral nerve injuries. Scientists at Washington University School of Medicine in St. Louis and Northwestern University have created a biodegradable implant that delivers pulses of electrical energy to injured nerves in rats, allowing the rats to heal nerves in their legs. The device is approximately the size of a quarter and only stays in the body for two weeks before being completely dissolved. John Rogers, a PhD of Northwestern and some associates created a device that wraps around a damaged nerve and gives pulses of energy for a few days until the device dissolves into the body harmlessly. The device is powered by a wireless transmitter outside the body that is similar to a cell phone charging mat. The researchers used the device to give electrical stimulation for one hour a day to the rats for either one, three or six days, or even no stimulation at all. They then the rat’s recovery for the following 10 weeks. Any stimulation was better than no stimulation at all at helping the rats to regain muscle mass and strength. The researchers also found that the more days of stimulation they gave the rats, the faster they recovered muscle strength.


While this may be all of the available research that has been presented in this article, there is research still occurring with scientists attempting to unlock the full potential of electrical nerve repair and a great effort to make the transition from rats to humans. When this research is complete, millions of people with nerve injuries will be able to heal much faster than before. While this is incredible, there are even more benefits to this research, that being the boost in research funding that would come with this kind of treatment. There is a visible need for this device to be compatible with humans and if these researchers develop this treatment enough as to where it is able to work on a human in an effective and noticeable manner, then more funding will go into the research department which would allow more availability for these great minds to research other kinds of technology. This idea supports the purpose of the article in question as well, showing that there needs to be an effort to get the word out about this research and its need for funding, making an article about the progress of research a way to do this. Another thing that this research does is allow scientists to question whether or not this kind of treatment could have other applications, such as repairing neurons in the brain or spinal nerves.
