I am Pandacorn

“When we are born, the deoxyribonucleic acid (DNA) in our bodies contains the blueprints for who we are and instructions for who we will become.” I wish Dr. Blue was here now. His words of wisdom, his words about me made me feel calmer but now that I’ve proved him correct what happens? Being one of a kind is challenging enough but learning about myself? Who thought I was up to that. Being a Pandacorn has played me my entire existence. Yes I have super speed of unicorns and super poop from panda’s but is that enough to make me shine? To make me special? Ever since that night I’ve never known if I should be happy about my transformation or if I should be miserable. Whenever I go back to that day it makes me wish I’d never ran away from my mum. I wish that I’d been like my brother, who always obeyed the ruled and played it safe. But we can’t change who we are can we? So this is my story of how I came to be.
(FLASHBACK)
“Just around the corner! I’ll just take a quick peek!”
I ran towards the edge. I leaned my head down and gazed upon the beautiful scenery in front of me. Ice cold water spread all around me. It sparkled in the morning soon. The trees at the bottom where full of bright green leaves. The grass gently swayed in the soft wind. Birds softly murmured their melodies as they danced above us and welcomed us into a brand new day. The air was filled with the smell of lovely nature. It was breathtaking. My gaze stopped at the very left side of the beautiful land. There stood the biggest and greenest pile of bamboo I’ve ever seen. My mouth watered as I gazed upon the tasty stalks of heaven. I smiled to myself as I laid eyes on a short steep path that led down to the platform filled with mouth watering bamboo.  I turned around abruptly and jogged towards the trial. Mother had stopped calling me by then so I decided I could use my luck a little longer. My sparkly silver horn sparkled in the sun as I made my way down the path. I galloped slowly watching not to trip over anything. I reached the bottom in no time and adjusted my eyes. The bamboo stood tall and hard and made my eyes go all the way around. I stepped closer and inhaled that beautiful smell.
“Mhhmmm…”
I murmured to myself as I let my head down, opened my mouth and took the first bite. It melted in my mouth. The taste flooded my tongue and slid down my throat without hesitation. I closed my eyes and enjoyed the rich taste. I opened my mouth again and grazed on the bamboo again. Slowly I let my bottom touch the floor and rest. My eyes were closed, body exposed to the warm sun and my mouth full of the magnificent bamboo. Nothing could ruin this magical moment. Slowly I dozed off into the world of dreams…Bamboo captured my mind and my eye lids shattered before closing completely.

(END OF FLASHBACK)
Why in the world did I need to fall asleep? I knew that we unicorns shared very similar DNA. I learned in school that 99.9% of my DNA sequence is the same as any other unicorns. The other 0.1% of our DNA difference has to do with the number of nucleotides in our DNA. All this Mr. Blue said was why all unicorns have trouble staying awake once hypnotized by something they love. I was clearly hypnotized by the bamboo. Dr. Blue also stated that 50% of our genes are shared between us, our siblings and our parents. Which meant that my brother should have the same affect when eating bamboo right? But he was always in such control and never broke rules. How come we were so different?

(FLASHBACK)

My dreams were suddenly interrupted when something stung my neck. I could feel it getting deeper and deeper into my flesh. I was paralyzed. I felt droll roll down my furry neck. Pain spread through me and I was unable to move. It paralyzed me. I knew something had bit me but I didn’t know what. Warmth spread through me. I felt like I was burning. As if the sun had become more hot. That moment Andrew’s words replayed in my head; “An important property of DNA is that it can replicate, or make copies of itself. Each strand of DNA in the double helix can serve as a pattern for duplicating the sequence of bases. This is critical when cells divide because each new cell needs to have an exact copy of the DNA present in the old cell.” Did that mean that know that the poison in the creature that was biting me would duplicate inside of me?! Will that completely change my orgasms? My eyes were beginning to close again and the pain duplicated. I felt as if I was changing. Growing. Suddenly the grip loosened and my body collapsed on the ground. My eye lids shattered again and right before they closed I coughed a glimpse of a baby panda running towards the woods. My eyes collapsed.

(END OF FLASHBACK)

I still remember waking up and feeling different. I felt fatter and for some reason warmer. I glanced down at my body and froze. I was covered in black and white hair. Quickly I got onto my four feet and galloped towards the water. When I saw my reflection I froze. I was half panda and half unicorn. Many unicorns in our village have mistakenly believed that the DNA with which we are born is the sole determinant for who we are and will become. So did that mean that they always knew I would change into a Pandacorn? Did that mean I was meant to be like this? No. Blueprints can predict things like how tall we will be or the color of our eyes but it cannot tell whether we will transform into something that hasn’t been shown to the world yet. Well now, it’s my time. Pandacorns are about to get exposed.

Crimson Waters Cause Several Sydney Beaches To Close

Crimson Waters Cause Several Sydney Beaches To Close
By Meera Dolasia

On Tuesday November 26th, World famous Bondi beach in Sydney's blue ocean water has turned *crimson red! They are an algae called noctiluca scintillans. 

       This crimson red water was caused by recent hot weather and heavy rainfalls in Sydney. This natural phenomenon also happened in the oceans around California. Noctiluca scintillans causes skin rashes, eye irritations, and the thick algae kills micro organisms and cause low oxygen in the area, causing marine animals in the area to die. Except for the skin rashes and eye irritations, they are no harm to humans. Fortunately, this phenomenon won't last that long. 
      Even though during the day, it looks red and scary, but at night, it glows electrical blue which normally should be dark. In California, surfers uses this fascinating characteristic and surfs at night. But why does it glow? The organisms become *bioluminescent caused by a chemical reaction that happens when the organisms shove/push each other in the ocean waves.


*Crimson: deep red (when scarlet is bright red)
*Bioluminescence: production and the act of releasing the light by a living organism


ASIMO

The article "I, Robot- Are Real Androids Ready for Their Close-Up?" by National Geographic describes about future robots and the humanoid robot, ASIMO. ASIMO, created by Honda,  is a 4 foot-tall robot that looks like a fatter version of the stormtroopers from Star Wars. ASIMO stands for Advanced Step in Innovative Mobility. ASIMO can do all sorts of things like humans can. He can climb stairs and even balance on uneven surfaces. Sony claims that their humanoid robot (QRIO) is the world's first running humanoid robot, however, ASIMO is now doing tours all over the world.    Scientists think that in the future they could make robots that can help patients, serve them food and drinks and administer medicines. They could also do dangerous things for humans like moving chemicals and fighting fires.

I chose this article because it seemed really interesting and it is not too long ago. I mean, just think about it.  A long time ago people were dreaming about this and now we have it. Last year I did a Current Event project that was about an endangered rhino and I checked on National Geographic because it has great reputation and is a known and reliable source. I think it could be good  for society because we can program these robots to follow certain rules and soon they could be driving for us in a safer way.

Batteries Powered to Heal


Battery Capsles

Batteries have limits. When a battery is charged up and used, some parts of the battery break down. For example, small cracks can form up inside the battery, blocking the flow of an electric current. This shows why a laptop battery will start to last less, sometimes even stopping to charge at all. Batteries could survive longer if we could heal the cracks. And that’s the idea for the new type of battery. In February, at the biggest general science meeting in the United States, an engineer called Scott White had an idea for a new invention:  A battery that can heal itself. Scott White and his colleagues knew that the small cracks, which often come up in the anode, can block the electric current and soon kill a battery. To fight the cracks, they added something extra into the anode: small plastic bubbles, or spheres, filled up with something called gallium indium. When the anode develops the small cracks, some of these bubbles break open and spill out the gallium indium. This material can heal up the crack, so that the battery can work properly and conduct electricity again.

When is a Rock Like a Magnet?



When is a Rock Like a Magnet?

When it's a lodestone? New research by geologist Charles Aubourg and his colleagues at the University of Pau shows that, when heated, certain types of rocks can actually become natural magnets. The strongest and most common is the lodestone. This is because lodestone is made-up of a mineral called magnetite, which creates a persistent magnetic field. The rocks Aubourg and his team used when experimenting also contained small amounts of an iron-bearing mineral called pyrite. The experiment was a long process which included heating a rock inside a strong magnetic field for 25 days at 50 degrees Celsius, 25 days at 70 degrees, 25 days at 80 degrees, 10 days at 120 degrees, and another 10 days at 130 degrees.

A Light Delay




A Light Delay

 Researchers stored yellow light for more than a second, by means of an imprint left in some of the atoms (dark blue) in a cloud of ultracold sodium atoms (gray). The beam that emerges (bottom) has the same properties but is weaker than the original beam (
Scientists from Harvard University found out how someone can keep light. A women called Lene Hau, a physicist, knew how to keep light for 1.5 seconds. What she wants to find out is like the game when a person whispers something to another person's ear and the other person has to whisper the same thing to the last person and the last person has to say the thing that whispered the first person. So the light is like the first person whispering it to the BEC (The BEC-Bose-Einstein condensate- is the fifth type of Matter that you can only find in coldest place ever. When the strangest known materials are put in the temperate of 0 degrees all of the atoms collapse into one tiny blob, that's called the BEC).

A Squirt of Stem Cell Gel Heals Brain Injuries


 

Title: A Squirt of Stem Cell Gel Heals Brain Injuries
Author: Sandeep Ravindran

Brain injured have always been one of the hardest body parts to cure. That is because brain injuries are very hard to fix. Since injured tissues swell up and can cause additional damage to the cells. Dr. Ning Zhang at Clemson University in South Carolina has created some sort of gel that can help cure the damaged injured tissues. "It has the potential to treat head injuries suffered in combat, car accidents, falls, or gunshot wounds." (Sandeep Ravindran) Since we do not have many ways to treat such damage scientists have tried inputting donor cells into the brain to replace the damaged ones. This however has not been working so well because, "The donor cells often fail to grow or stimulate repair at the injury site, possibly because of the inflammation and scarring present there. The injury site also typically has very limited blood supply and connective tissue, which might prevent donor cells from getting the nutrients they require." (Sandeep Ravindran) However the gel can be filled with chemicals that will help the donor cells get planted in the brain properly and receive the nutrients and blood needed to sustain and heal the injury. They have tested the gel on many different rats with severe causes of brain injuries and it has shown huge results. "Dr. Zhang loaded the gel with immature stem cells, as well as the chemicals they needed to develop into full-fledged adult brain cells. When rats with severe brain injuries were treated with this mixture for eight weeks, they showed signs of significant recovery." (Sandeep Ravindran) This gel might be something that will help us save many lives and the new pathway ahead. With the results we are getting now the gel might be ready to be tested on humans in about three years.
