Science Is Her True Love

I have loved science since I was a child watching the Magic School Bus and Bill Nye The Science Guy. As I grew and started learning more complex sciences I found that Biology and Chemistry were among the most fascinating things I had ever encountered. I decided when I was about 13 that I wanted to be a scientist. I wanted to work with some of the best scientists in the world. I wanted to accomplish something great. I am now working on my associate's degree in Biotechnology at Athens Technical College, in Athens, Georgia. As soon as I finish that I plan on transferring to the University of Georgia (also here in Athens, Georgia) to eventually obtain my doctorate in Biotechnology. I started this blog not only because I love science and everything about it, but because I wanted to chronicle my path to my dream. Starting with my most basic learnings (like my Biology 1111 and BTEC 2000 classes that I am taking right now) to the day I obtain my doctorate, you guys will be following me. Please, tell your friends to follow. After all, it is not an easy task I am setting out on and could use the support! I hope you enjoy this blog as much as I am going to enjoy writing it.
A Note To My Followers

"As the polar ice caps melt, ocean levels rise. It is expected that ocean levels can rise as much as 250 to 300 ft. ” This is wrong: 1. As sea ice melts, sea level does not rise. (Put ice cubes in a cup and add water. Because the ice was already there, it’s change of phase does not cause the water level in the cup to rise.) It is the melting of glaciers (ice on land) that adds to the sea level. The largest contributor to sea level rise is likely thermal expansion (as the water warms it takes up more space, increasing sea level)  In addition it is VERY unlikely that we will observe sea level rises that high.  There were several other errors in your post as well. If you are using this for class or planning to make further public posts, I can give you my email and I will help you make sure you’re not just posting sensationalized science- but actual science. It is just as important not to exaggerate as it is to not deny global climate change in general. -submission from thesaratea

All of the information in that post came from my Biology (BIOL 1111) teacher. I may have misunderstood some of the things he said, but as this is for a test that I have Tuesday, could you kindly tell me everything that I have wrong?

unravelingtheuniverse is my science blog :)

Cool I will check it out!

hey, that plasma membrane link isnt workin... would u be able to send me the article or whatever it is. pretty please

I am so sorry that link is no longer available. I did however find this link and I hope it helps. If you need something more or need a little help, feel free to ask me! I have no problem trying to clear some things up! And thanks for following

Mouth of Giant Black Hole Measured for First Time

For the first time, scientists have peered to the edge of a colossal black hole and measured the point of no return for matter.

The black hole is spinning at half the maximum rate, and its mass is that of the black hole at the center of the M87 elliptical galaxy.

A black hole has a boundary called an event horizon. Anything that falls within a black hole’s event horizon — be it stars, gas, or even light — can never escape.

“Once objects fall through the event horizon, they’re lost forever,” Shep Doeleman, assistant director of the MIT Haystack Observatory and research associate at the Smithsonian Astrophysical Observatory, said in a statement Thursday (Sept. 27). “It’s an exit door from our universe. You walk through that door, you’re not coming back.”

Although the event horizon is an imaginary line that’s impossible to observe, astronomers have imaged the region around a giant black hole at the center of a distant galaxy, and measured, for the first time, the closest stable orbit in which matter can circle the black hole. The findings were reported today in the journal Science.

The supermassive black hole in question lies at the center of the galaxy M87, which is about 50 million light-years from our own Milky Way. This behemoth black hole contains the mass of 6 billion suns.

Artificial Uterus Sheds Light on EmbryosPioneering work by a leading Univ. of Nottingham scientist has helped reveal for the first time a vital process in the development of the early mammalian embryo. A team led by professor of tissue engineering, Kevin Shakesheff, has created a new device in the form of a soft polymer bowl which mimics the soft tissue of the mammalian uterus in which the embryo implants.

Prosthetic Breakthrough Might Fuse Nerves With Prosthetic Limbs

A replacement limb that moves, feels and responds just like flesh and blood. It’s the holy grail of prosthetics research. The Pentagon’s invested millions to make it happen. But it’s been elusive — until, quite possibly, now. The body’s own nerves are arguably the biggest barrier towards turning the dream of lifelike replacements into a reality. Peripheral nerves, severed by amputation, can no longer transmit or receive any of the myriad sensory signals we rely on every day. Trying to fuse them with robot limbs, to create a direct neural-prosthetic interface, is no easy task.

I believe connectomes are the meeting ground for nature and nurture. The gene controls how the brain wires up, but experiences also modify the connections of the brain.”- MIT Neuroscientist, Sabastian Seung [via]

Most of you have heard of the Human Connectome Project. If not, have a look.

Using “state-of-the-art diffusion-imaging scanner” images of neural pathways are collected via a MRI looking machine, which allows scienctists to view connections of the brain “by tracking the passage of water molecules through nerve fibers, giving a more accurate picture of the brain’s structure and its neuronal pathways”. [via] Eventually, the idea is to identify connectopathies (abnormal circuits) then treat with appropriate pharmacology targeted for that area.
