    Summary of the Article
    The change from a teen to an adult brain is unclear and does not happen overnight. Brain development can take place until your 20s. New research predicts that the U.S. justice system has major impacts on brain development. The case of Kalief Browder supports these new predictions. Brower was 16 when accused of stealing, unable to pay his bail, he was thrown into a violent jail for three years. He spent most of his time in solitary confinement, a toxic place for children to grow up. After his case was dropped and he was released, a few years later he committed suicide. This case is now used as a key for showing the negative effects of jail. The violence, stress, and isolation of jail all interfere with brain development. The brain being fully developed is measured by so many different things it is hard to tell when it is complete. Teen brains still developing come with many problems when they are involved with law enforcement. People suggest that teen criminals should still have consequences for their actions, but should focus more on rehabilitation.

    This article was a real eye-opener. Learning about how the government might be harmful to adolescents is a big problem. This article has good evidence that can be really useful to future court cases. The science behind jail affecting the brain is very educational. Without people realizing this, we could continue to have dangerous impacts on children. Hearing about a personal story that the research came from made the topic seem more real. The descriptions of how jail is for teens are terrible and the article makes sense that it is not healthy for young adults. I felt very curious after reading to know about more research collected. The article is not something I would generally choose, but I’m glad that I’m staying aware of various topics.

    Author: Aimee Cunningham

    Publish Date: September 6, 2019
    Summary of the Article:
    Five deaths and possible 450 cases of lung illness and injuries reported in the U.S. This is more than double the 215 cases that were reported a week ago. All of these problems are tied to the cause of vaping. The type of substance or vaping device behind these cases is unclear. Vaping and E-cigarettes are harmful to everyone, but particularly to youth, young adults, and women that are pregnant. A possible substance suspect could be vitamin E acetate, found in vaping products with cannabis. Specifically, vitamin E acetate is used in dietary supplements related to skincare but can be very harmful to inhale. Products like Chronic Cart (sour patch and Runtz) and Dank Vapes (diamond og) have been sourced with vitamin E acetate. Most samples that are used to find a source product are a mix of many different things leading to no stable conclusions. Chemicals found in vapes could include nicotine, THC, additives, pesticides, or opioids. Most patients are claimed healthy before falling to illness. A new study tells how 61% of patients used nicotine products, 80% used products with THC, and nearly half used both. Human lungs are not meant to handle such chemicals and toxins that can be inhaled using vape products. Even if substances in vape products are considered safe to eat, they are still harmful inhaling in our lungs.

    The main reason I chose this article was to stay aware of the great hazard of vaping. I had also read about one of the deaths caused by vaping on social media and I wanted to know more about the research. Vaping is such a huge epidemic, especially targeting youth and I am glad to see that research is being conducted to find a source of the problem. Even though they have not found a particular target it is interesting to see what they have developed so far. Including the vitamin E acetate research, and what products are connected to that chemical. I would be interested in more about the chemical and test leading up to the finding. Another thing interesting in the article was the data from a recent study. It gives a real perspective on the things happening around us, and how sad the impact is. The whole article is a really good education tool if you don’t know a lot about vaping I would consider this a great eye-opener. Knowing that vaping is bad and knowing why vaping is bad is a huge difference. Learning the science behind it and what it actually does to your body has a greater impact. Overall the article was packed with knowledge and was very detailed, I’m glad I read it.

    Title: “Climate change may cut soil’s ability to absorb water”
    URL: https://www.sciencedaily.com/releases/2019/09/190911151204.htm
    Author: Science Advances
    Website: Science Daily
    Publish Date: September 11, 2019
    Summary of the Article
    Climate change can affect the world with many harmful factors involving our coasts, ecosystems, weather, and human health. Climate change is impacting the way soil absorbs water. Reduction of soil absorption can affect groundwater supplies, food, storm drain runoff, biodiversity, or ecosystems. The change in soil could happen globally and even rapidly. The direction, rate, and magnitude of changes should be involved for future predictions of the response to climate change from the ecosystem. The water that takes place in soil is responsible for carbon, changing absorption can also throw off the levels of carbon dioxide in the air. Climate changing also increases the levels of precipitation. Higher precipitation levels could lead to less infiltration to the soil, more erosion, and risk of greater flash flooding. These factors will influence the amount of water for plants and evaporation in the air. A test in Kansas involving sprinklers found that an increase in rainfall lead to a 21-33% reduction of infiltration and only minimal increase in the reduction of water in the soil. The next studies will involve testing other regions of the world and use them to make more predictions of climate change.

    Overall I thought this article was great and related to some topics we are learning in class. For instance, how we learned about water. Climate change is a serious and unknown thing, learning more about it is a good tool for education. I did not even know that climate change could change the way soil absorbs water. This was my main interest for choosing the article because it sparked my curiosity. Because the climate could change this one thing in soil, it leads to so many other questioned problems. Learning about how exactly the water could change so many things makes me question all the things we still don’t know about climate change. An interesting topic that I found in the article was the talk about how the infiltration would vary with the change in absorption. I enjoyed the learning experience the article gave.

    Title: “Pancreatic cancer tumors attack the blood vessels that deliver chemo drugs”

    Publish Date: September 4, 2019
    Summary of the Article
    New research on how pancreatic tumors harm blood vessels with chemo drugs in them has sparked. The tumors get to the blood vessels before they can deliver the drugs to the pancreas. Scientist are now zooming in to see how the tumor attacks the blood vessels. A drug that could allow the chemo drugs to proceed through could do an impossible task. Pancreatic cancer is one of the deadliest cancers and understanding how it works is not easy. This is because it is embedded far in the skin and has potential problems trying to monitor it. There is a mock experiment of how a pancreatic tumor and blood vessels would react, it showed that the tumor overtook the blood cells and killed most of it. This research could explain how tumors spread so quickly. This experiment potentially also found how the tumors actually kill the blood cells. All of this research could be answers to desperate questions. Further research will involve how this drug interacts or works in other experiments and variables.

    This article was absolutely excellent. The whole article kept me interested and fascinated. Because cancer is such a scary thing for many people and leaves them with no answers, it is awesome to see advancement in research. Finding answers to things that were thought to be impossible is a great thing to learn about. I enjoyed the part of the article where they took their research to the next step and set up an experiment. Reading about how they got potential answers to their observations was very interesting. The whole article makes me want to educate myself more on other research happening with cancer.

    Title: Decades of dumping acid suggest acid rain may make trees thirstier

    Author: Carolyn Wilke

    Publish Date: August 5, 2019
    Summary of the Article
    With a long experiment in the Appalachian Mountains, evidence points out that trees are becoming thirstier. The experiment involved a mock acid rain and a plot of trees, compared to a plot of trees with no acid. The acid that could be causing this change comes from industrial activities, agriculture, and the burning of fossil fuels. The study showed that the treses with acid, soaked up a lot more water compared to the others. Acid can also dissolve minerals in the soil and deplete its calcium. Without the right amount of calcium, plants cannot control water loss. Thirstier plants lead to great concern. Trees taking more water can leave less water available to animals and plants. The water these trees are taking is not a small amount but is actually a large quantity. Ecosystems are unpredictable and every decision we make for our environment always leaves us with an outcome.
    Personal Reaction
    This article was very shocking. I love staying updated with changes in our environment. Reading about the different ways we are impacting the environment brings me great curiosity. A part of the article that I enjoyed was the experiment. The experiment made the whole article seem supportive and gave it a stable point of reference. The article involved input from many different scientists, which was also very intriguing. I wish the article had more information on the acid rain itself because this was the big cause of this new research. Some opinions on what we could do or what other research we need would also be great to include. The article really makes me want to read more on trees and how they affect the ecosystems with their water intake. Overall I thought the article could be very helpful for future advancements and is a start to more environment changing education.
