Chocolate, not only a sweet tooth!!

Now you have an excuse to eat chocolate to your heart's pleasure. Did you know that DARK chocolate helps the heart from inflammation and heart disease? Remember, DARK chocolate, not milk chocolate! :) According to health studies in europe, that one dark hershey kiss could help the heart. Chronic inflammation could a risk factor for some diseases so maybe one or two DARK chocolate kisses could help. The first hypothesis from a group of researchers was that the high amount of antioxidants contained in the cocoa seeds might have beneficial effects on people. The results gave backup information by helping people have lower C-reactive blood cells which cause inflammation. Or in another way, they have less heart bun or inflammatory. Chocolate may be good for you, however if you care about your diet, be careful not to overdo it!

From Electric Cars to Electric Planes...

Electric planes can be the new style to how modern people fly. Electric motors are 3x or 4x faster than an airplane propeller. Plus, it could be much more reliable than the current modern plane. What this means? Less accidents, more business. Plus, if an electric airplane would be able to be efficient 95% of the time. This means that they waste much less! What makes me even happier is that there would be quieter planes. I always hate that noisy sound at night. It makes me wake up sometimes... However, the negative thing about this soaring plane is that the battery. The battery would need mass amount of electricity to pull off a flight. This would make the plane much huger and heavier causing unsafety to the passengers and the plane itself. Nanosolar, a company tries to solve this problem by adding solar panels under the wings to recharge the batteries. Not all planes are destined to be run on electricty yet this plane still has some advantages still. If more electricty planes are made, this means more airports so no one can complain about the noise. This idea can lead to success but we'll have to wait and see in the future.

Tuna-Fish is Lower Mercury level?

Usually when you at a restuarant, you expect you sushi to be safe and poison-free? Wrong! After reading Livescience.com's article, you will end up watching what your eating now. A new static says that it is safter to eat tuna from a grocery shop than from a restuarant. However, that doesn't mean a thing compared to other fishes. In fact, tuna is probably one of the highest edible mercury fish. Listen up as you read my blog!

SUSHI DNA:

Previous studies shown before say that there is a few diffrent mercury levels for each fish. These studies isn't reliable because they didn't have a good method for seperating the tunas. As you can see, there is a new way to determine a type of salmon. It's called DNA barcoding. In this method, scientists use a "species's fingerprint" and compare it to an unknown species. This comes in handy since some of the markets or restuarants don't even know what type of tuna they're selling! This show that some markets or restuarants could be giving you some bad fish...

However, which one gives you the better fish more?

THE EXPERIMENT:

The reseachers for this experiment took 69 samples of tuna from restuarants and markets. 54 from restuarants and 15 from supemarkets... The mercury levels were much higher than your average fish. In fact, the tuna, bluefin akami broke had a higher mercury level allowed by the USA Food and Drug Administration:

THE HEALTH RISKS:

The mercury level rises in the food chain. For example, a fish that is a predator, has a higher

mercury level. If you eat mercurary, the risk are disabilities and other serious problems that can't be fixed.

3-D TV = A Trip to the Hospital?!

After reading an article on livescience.com, there could be a risk of hurting your child from 3-D. If you feel dizzy, have altered vision, or anything else, you should take off those 3-D glasses and go to you doctor. Samsung, the company that stated why this is happening, wants to help awareness of 3-D TV since they didn't want to repeat what had happened in Japan before. There was seizures from pokemon due to the flashing graphics. 12,000 children had illnesses from seizues to nauseua. The nintendo company had no choice but to cancel this episode in case any damage happens. The author of this article at Livescience, Benjamin Radford's interesting theory was every 1 in a 5000 people are at risk of photosensetive elpilespy. This could result in a bad vision, fatigue, or nauseua. However, america shouldn't be worried about seizures.Bad excersises like video games are a much more important health topic. Beware of the 3-D action still...

Collapsing Can LAB!

While my group was at the collapsing can lab, it was  a fun and cool experience I had seeing all the cans popping and so forth. The materials we need were a heater, a empty can filled with water, and a bucket full of ice and water. First, we let the water on the heater evaporate for a little bit causing steam. The steam was caused since the metal of the can sealed the pressure just like your average kettle.  After that, the steam in the can came from the water evaporating the water. Before you knew it, steam was forced to come out. Quickly, we put the can into the bucket of  ice cold water. As a result, it made a huge clang. This had happened since when the can began to evaporate, the cold water made the can's water also condensed. The two diffrent reactions couldn't break through at each other. As a result, it collapsed from the pressure. This was a fun lab to do and I hope I can try it again!

The Popcorn's Radiation Reason

You'll pop when you realize about why popcorn pops. The answer is all hidden in here :). So you're wondering, what causes the popcorn pop? Well actually the secret ingredient for making it pop is something called water! Each kernel contains a hard outer shell and a little water inside. When you finally microwave it, the kernels are evaporated and from the pressure, it causes the popcorn to blow up. As more steam comes, the popcorn soon lets out a pop from the shell not being able to hold in the pressure. At least, you hear the classic POP! This turns the kernel inside out and showing it's bright yellow starch.

The atmosphere Activity

Website I learned about Atmosphere: Http://forces.si.edu/atmosphere/interactive/atmosphere/html

From this website, I learned about many things about the atmosphere. I figured what Carbon dioxide does, how oxygen helps, and what the ozone layer does. I'm going to write about my experience here.

Carbon Dioxide:

Carbon dioxide is a gas that retrieves heat from the sun and makes less than one percent of the environment. It comes from volcanoes, automobile exhausts, factories, power plants, and decaying plants and animals. I didn't know that the oils we use come from dead decayed animals that were buried in swamps 350 million years ago. This is why global warming started since we used those fuels too much from cars and so forth. That explains why they call it fossil fuels!! What had also surprised me that other planets had carbon dioxide! For example, venus had it yet it is too thin, that there wasn't enough carbon dioxide to keep the planet above -81F. On Mars, it's so dense that the temperature, that the temperature is 873 F!!

Oxygen:

Oxygen which is air that helps us breath formed 4.6 billion years ago. It started as a cyanobacteria which made oxygen through photosynthesis. I didn't know that! Today, oxygen levels rose and now they fill up 1/5 of the earth's atmosphere. Oxygen first formed on earth by the sun's ultraviolet radiation that broke the molecules of water. Today, our oxygen comes photosynthesis which comes from plants that use the sun's energy to convert carbon dioxide and water into oxygen.

Ozone:

Ozone is a gas that has three oxygen atoms. It shields the earth from sun's ultra violet lights. What surprised me was that aerosol sprays and refrigerants caused the ozone layer to thin i n 1980. When these got banned, the ozone layer stopped growing, however, it's expected not to close in 40-50 years. Another about ozone is that is called photo chemical smog at ground level. It's so reactive that it causes people to burn their lungs. Kids breathe more than adults so we kids get more affected. I'm amazed by ozone.
