Chocolate Reduces Stress, Study Finds

By: Carla Moskowitz

There has been some new evidence that eating dark chocolate every day can reduces stress! People who have rated themselves highly stressed with lower levels of stress hormones after eating chocolate everyday for two weeks! The subjects of this study ate 1.4 ounces of dark chocolate a day. To prove this study doctors took urine and blood plasma samples of the participants in the beginning, middle, and end of the two week study. From these samples they found lower levels of the stress hormones cortisol and catecholamines in samples at the end. Written for everyone to see by the researchers; "The daily consumption of dark chocolate resulted in a significant modification of the metabolism of healthy and free living human volunteers with potential long-term consequences on human health with in only two weeks treatment." Also "This was observable through the reduction of levels of stress-associated hormones and normalization of the systemic stress metabolic signatures." This research shows that certain substances in chocolate such as antioxidants called polyphenols can be helpful health benefits. Previous studies have found chocolate does help fight heart disease and help prevent the chance of developing cancer. But since chocolate is not very healthy for the reason that it contains a lot of sugar and fat you have to watch how much of it you eat. My opinion is that a lot of people will like the fact that chocolate reduces stress because then they could eat more of it. Which will lead to more people being obese and a lot of people in this world are already obese so i don't believe saying to the world dark chocolate reduces stress because people will take advantage of it.

Extra Credit (tv show)

A show that I watched that connects to science is, Survivor. Survivor connects to science in a few ways. One being they have to deal with the weather and adjust to it, which involves science. Also in order to survive they have to think in scientific ways to keep them safe and covered, like building a shelter. As well in challenges they have to think outside of the box when they have challenges that include science. Lastly, and most important, they have to make fire. Making fire involves science. So science is connected to the TV show Survivor.

Another Choice Responce Quote

In Science the credit goes to the man who convinces the world, not to the man to whom the idea first occurred.

Sir William Osler (1849-1919) Canadian physician.

This quote means to me that even if you discovered something, you might not get credit for it. This might happen because someone else tells the world and teaches it to them and they understand it. So even if you discover something you have to take charge of it, and tell the world what you discovered.

Matter

Matter is anything that has mass and volume. Matter is also what the universe is made up of. Four general properties of matter are mass, weight, volume, and density. Matter stays the same no matter where you are. Also mass is the amount of matter in an object.

Matter is everything around you. Also anything made of atoms and molecules are matter. As well matter is related to light and electromagnetic radiation. States of matter are solid, liquid, gas, and plasma. Matter is made up of particles. The temperature of matter depends on how fast the particles move and how much they move.

Matter is very important. Matter controls many things. I believe matter is easy to understand because it is everything, and since it is everything it is easy to learn. Matter is also important to understand. Matter helps you understand why certain things are the way they are. That is my opinion about matter.

Wolves Beat Dogs on Logic Test

Wolves Beat Dogs on Logic Test
by: Carla Moskowitz


Wolves do better on some logic testes than dogs. This happened for multiple reasons. One reason is because dogs follow human cues. Since they follow human cues they act more like human than animal. Also dog responses are similar to human infants, and human infants follow adult humans. It makes sense to why they act like humans because they are with humans so much, and they are practically raised by humans. But wolves make choices based on there observations. So they do more on they're own then dogs do. A test scientist would have them take is...they would repeatedly place an object in box a, and they would allow them to look for the object. But when they switched the object to box b human babies and dogs got confused and continued looking in box a. Wolves easily followed evidence with there eyes and found the object in box b. Neither wolves or dogs are smarter than the other but they are smart in different ways. For example, without humans wolves are smarter, but dogs are smarter when they have to survive in human enviorments. So in all wolves do better on some logic tests, but a wolf or a dog is not smarter than the other.
