    Title: Disabling one protein might one day lead to a cure for the common cold
    Author(s): Sofie Bates
    Published by: Science News
    Date: September 24, 2019

    Story Summary: Most humans tend to catch 3 to 4 colds every single year. Scientists are finding a gateway to take a bigger step to be able to find a cure for the common cold. They have found a route protein in humans that a few viruses can use to duplicate inside human cells. Scientists found this key protein using a gene-editing tool CRISPR. They used a hook to take out human proteins that were connected to a viral protein. They found a protein called SETD3 that was scattered and taking over the cell. They used mice to experiment with this protein, they inserted a virus that will control the SETD3 gene to see how it would affect the mice. The mice did not get sick, but the babies had trouble coming out during birth. Scientists don’t have any idea how this virus will affect humans as of right now so they are going to try to find a drug that will either simply blocks this protein or one day completely destroy it.

    Personal Reaction: My personal reaction to this is I am happy they are trying to find a cure to the common cold but I am also very concerned about how this could affect humans. First off I am happy they are trying to work towards finding a cure because colds affect almost everyone, every new season begins with a cold. There is barely any medicine you can take for it also, so with a cure we wouldn’t have stuffy noses and itchy throats. Although I am very concerned about the virus they injected into the mice, I understand they did not get sick but they had trouble getting their children out of the womb. That could be terrible for humans to go through, and there could be many other side effects that we can’t even think of. I support their decision on holding off with the virus until we 100% know what can happen.

    Title: Drinking More Sugary Beverages of Any Type May Increase Type 2 Diabetes Risk
    Author(s): Science Daily

    Date: October 3, 2019

    Article summary:
    Humans who raise their intake of surgery drinks have an increased chance of suffering from type 2 diabetes. Even if these drinks include artificial sugars people still have a chance of getting type 2 diabetes, as stated in a new study at Harvard T.H. Chan School of Public Health. For their study, they looked at over 192,000 men and women to see how consuming 4 ounces of artificial and regular sugary drinks every day, affected them in 4 years. After 4 years went on they found that people higher their chance of type 2 diabetes of 16% if they consumer sugar-sweetened drinks, while people who consumed artificial- sweetened drinks higher their chance of 18% of type 2 diabetes. The study also found that replacing one serving of sugary drinks each day with water or other healthy drinks can lessen your chance of type 2 diabetes by 2%-10%. In conclusion, people need to moderate their intake of sugary beverages if they want to lessen their chance of type 2 diabetes.
    Personal reaction:
    This article really took me by shock when I first read this. I grew up thinking artificial sugars were good for you, like diet coke, and other diet sodas. I had no idea that drinking 4 ounces a day could increase by 18% of type 2 diabetes. We did not fully talk about this is class but we did talk about sugar and glucose. I think this information could definitely impact people’s choices of sugar intake because many people just drink not thinking of how it can affect them in the long run.

    Title: Fruit flies live longer with combination drug treatment
    Author(s): Science Daily
    Published by: Science Daily
    Date: September 20, 2019
    Article Summary: A new drug combination has been used to keep fruit flies living longer. This combination has been founded by UCL and the Max Planck Institute for Biology of Ageing. It consists of 3 dugs that have been used in the medical field for a while now, “lithium as a mood stabilizer, trametinib as a cancer treatment and rapamycin as an immune system regulator” (Science Daily). Researchers had a hypothesis that this could help people with age-related illnesses and simply slowing down the aging rate of humans. The three drugs all move in opposite cellular communication routes that combine to construct the nutrient-sensing network. “This network adjusts what the body is doing in response to changes in nutrient levels” (Science Daily). They texted an experiment on the fruit flies to see what would happen if there were only one of the individual drugs compared to if there were 2 or 3 of the drugs that make up this combination. They found that with only 1 drug the fruit flies lived 11% more lifetime, with 2 drugs combine they found that it increases their lifetime of about 30% and with the entire 3 drugs combined make their life 48% more. Researchers are very impressed with these results and they are going to go more in-depth and try different experiments with different animals. Once the experiments move to an animal that is very complex, they will eventually possibly use this combination on humans.
    Personal Reaction:
    This article really stuck out to me once I read that it could possibly help people with age-related illnesses. I have had many relatives that have gone through cancer and other diseases because of their health and their age. I think this combination of drugs could really help people if tested well on other complex animals.

    Title: New defensive mechanism against bacterial wound infections
    Author(s): Science Daily
    Published by: Science Daily
    Article Summary:
    Skin wounds caused by bacteria can lead to intense inflammation. Researchers from Charité and the university of Universitätsmedizin Berlin have found a new attacking mechanism that can help kill bacteria and other pathogens in our skin to prevent inflammation without using antibiotics. Researchers investigated their hypothesis that mast cells could help fend off pathogens in our body. “Mast cells are responsible for the body’s response to otherwise harmless substances, producing symptoms such as runny nose or itching” (Science Daily). Researchers tested their hypothesis on an animal with a wound to see what would happen if there was an absence of mast cells in the wound. After 5 days the researchers concluded that the wound had 20 times the number of bacteria if the mast cells were absent from the wound. The researchers found that the reason for the mast cells killing the bacteria is a product of a messenger molecule called interleukin 6. Interleukin 6 is a molecule that causes skin cells to release antimicrobial peptides which are short protein chains that eliminate bacteria and additional viruses.
    Personal Reaction: My reaction to this is that I think this research could help doctors and nurses when it comes to wounds. Medical service providers have limited resources when it comes to treating wounds, so understanding what cells and molecules can help eliminate bacteria will be very beneficial. This relates to what we learned in class because in our first unit we talked about peptides and protein chains, and this article talks about the interleukin molecule that releases antimicrobial peptides that can exterminate bacteria in wounds.

    Title: Genome-edited Bull Passes on Hornless Trait to Calves
    Author(s): Science Daily
    Published by: Science Daily
    Date: October 7, 2019
    Article Summary:
    For the past 2 year researchers have been experimenting with six dairy-bull offspring that have been genome-edited to see if they can stop these bulls from having horns. These researchers are from the University of California. Genome-editing will be a great alternative to dehorning and other possibilities that can cause injuries to bulls. After the 2 years, none of the offspring have been born with horns as they expected. They also identified that there were no other different qualities of the bulls than of their parents. Four of the offspring did inherit a piece of DNA which was a plasmid. It can be directed by screening and choosing. The plasmid did not hurt the animals but it made the bull considered as a GMO because it held remote DNA which in the end considered it to be a bacterial plasmid. The researchers feel that genome-editing would be a great way to keep out dairy-bulls safe and healthy.
    Personal Reaction
    My reaction to this is very happy that we finally have a solution to dehorning bulls. Dehorning bulls is only one of the terrible things that happen if the bulls have horns. Humans also practice on the bulls to protect other cattle. This is similar to what we talked about in unit one about DNA, it says in the article that 4 of the 6 offspring inherited new DNA after Genome-editing. I think that Genome-editing will be a great way to stop the crucial hurtings of bulls.
