This week we are moving away from the more abstract, conceptual areas of chemistry and getting into the computations. Our studies will begin with developing a familiarity of the measuring units we typically use in science and then proceed into some analytical techniques. Below are handouts for the work in this unit.

This article is about 3D printers and how there are endless possibilities to what they could do. In this article it talks about all the food that people have experimented with printing and the shapes they created with food.

When I think of printers, I think of black ink letters on paper. I never imagined that this would even be an idea. You made a very valid point in the sense of places being put out of business due to lack of income if this were to happen though; which is a scary thought. This sounds so futuristic and movie-like to me and probably also to many others. Maybe our world is finally advancing at the pace we would've assumed years ago. I can't wait to see these results.

This article is called the "Monkeys born with edited genes". This caught my eye as genetic modifications has always been a strange & weird, but fascinating topic. In this article, it talks about how scientists edited 2 of these monkey's genes by using molecular scissors first discovered in bacteria. What was interesting is that the purpose of the experiment was to find ways to cure humans who would be born with defects. They could go snipping out & replacing the mutated dna that you would be born with. This seems a bit like a precursor to the day when we may have genetic modification made to us - like enhancing vision, sounds we hear, or making our immune systems stronger.

I came across this article while navigating through the Reddit science section, duh. I was skimming through subsections and found this in Neuroscience; an article titled, "Your memory rewrites the past and edits it with new experiences, study finds."

I think that it's a good thing that we are able to evolve with our thoughts. It's not real scary because it happens naturally and it helps us process new information.

I knew that not remembering your memories properly was possible. There is a quote from John Green that says, "You don't remember what happened, what you remembered becomes what happened." (or something like that). But the fact that your memories can be altered by current experiences is definitely weirder. I would like to learn more about this.

I found this article on a website called Chemistry Times. It is about researchers in India who came up with a way to convert plastic material into fuel using low-temperature conversion. This is interesting to me because it solves two problems at once: fuel shortage and the large amounts of plastic waste taking up space in landfills. They are able to create engines that run on common types of plastics such as polymer. At first, I thought that this was kind of a bad idea considering burning plastic leads to huge amounts of pollution, however after further reading I realized that the low-temperature method results in a low amount of hazardous emissions. I think that it is an interesting step into the future of fuel and an overall cool idea.

I found this article by going on the Science Daily website and looking through the articles categorized as insomnia.

This article instantly intrigued me because I find archaeology really interesting to begin with. This article is about how recently archaeologists have discovered the oldest human foot prints ever discovered. They were found in Happisburgh, Norfolk after rough sea waves washed away sediment to revile a very old layer of hardened mud that gave way to foot prints of early humans.

I found this article under the Biology subsection of Reddit Science.

This article is about the fact that we might not even have 6 basic emotions—surprise, anger, happy, afraid, disgusted, and sad. After doing multiple tests of comparing the facial expressions for those emotions, they noticed that anger and disgust had similar facial expressions, along with surprise and fear as well. Researchers say that earlier on in life the emotions are very similar, but as we grow older the emotions become more distinct. Meaning, the difference between surprise and fear and anger and disgust are less biologically affected and more socially affected.

I found this article on redit in the psychology section.

This is a psychological article talking about how a mother's stress can affect their baby when the baby is in the womb. The article was saying there are two ways a baby can react to something new and how they react can determine the baby's mental issues and problems they may have when they get older. One way they could react is in joy and excitement, even curiosity. The other way they might react is with fear and confusion. The baby's who reacted with fear came from stressed out mothers. The main stressed out women are women who live in poverty and had their child very young.

This article is about NASA trying to find water vapors from other planets. They found one and its leading to another chapter about alien life. I was wondering if they were looking for water vapors because they are trying to find another planet where we can live or because they are trying to find another form of life(aliens). If its aliens then I believe that there are aliens by I don't understand why they want to find them so bad. But if its to find another plant we can live one I want to know why? is it because something is wrong with our plant? Is it because we cant live here anymore? Why is it they are looking for another plant like ours? This article brings up lots of questions

This article is saying that usain bolts superhuman speed could alow him to fly like a bird in a wing suit on one of saturns moons. ''The world-record holding sprinter has reached top speeds of 12.27 meters per second, which would be fast enough for him to take off on Titan while wearing a regular wingsuit. Theoretically, the Olympic athlete would then be able to soar above the planet – without any need for propulsion.'' I found this hard to belive but still interesting

In this article I read about how in Europe the water quality is getting worse and worse due to agriculture pesticides getting into the water when it rains. This reminds me of something similar that happened in the San Diego desert. 20 years ago there was many farms around the salton sea. One year it rained so hard that it washed all the pesticides down into the lake. To this day the lake is still nasty will a bunch of dead rotting fish around the bank. I hope this same thing doesn't happen to the Europe waters because I think it could affect the US if the water gets over to north America.

This article from Newscientist is about a star called the Eye of Sauron located in the southern constellation of Centaurus which is 4.4 light-years from Earth. From it explaining the picture that glowing ring is a dust ring, but one thing I'm wondering is why is it glowing that bright, shouldn't it be radio active? Could it be a star exploding?
