Final Reflection

When I first walked into this course, I did not know what to expect. I was not sure what I was going to learn and how deep we were going to delve into the science and technology aspects. After taking this course, I ultimately realized that there is so much to learn about the world of science and technology, how they are connected, and what future opportunities are waiting in these fields. Through all of the major and minor assignments and projects, including scientific presentations, hot topics, hands-on labs, BioBlitz, and 3-D printing through MakerHub, I learned so much more than I anticipated when first thinking about this course. Such are the reasons why I genuinely enjoyed this course and the amazing professors that took the time to really help us grow and mold our scientific thinking.

Putting the two major projects (the BioBlitz and 3-D printing model for healthcare innovations with MakerHub) aside, the smaller assignments were just as significant to the course. Working on the hot topic presentations, I gained an understanding of how much research, time, and effort went into putting everything into one final project. From this assignment, I realized that it is extremely important to know the sources you use when finding information, how to read and dissect primary scientific sources (articles and journals), as well as popular secondary sources. Working on the labs actually reminded me of the times I worked in my physics lab in high school and conducted many interesting experiments. But with these labs that I worked on, I got to experiment with real chemicals and products that are used by scientists, chemists, and physicists all the time. I definitely understood the importance of safety, structure, and organization when working not only in a lab, but in any other setting that requires these aspects. These assignments and projects were meaningful and impactful because it taught me different lessons that apply to a wider array of situations, other than a scientific setting.

But what I really took away from this course was everything I learned through the two big projects. Walking through Inwood Hill Park during the BioBlitz was an interesting experience (especially because I was carrying a full laptop bag and a suit in another large bag with me the whole time; I had an interview just before in case you were wondering), primarily due to the fact that there were so many different factors of a park that I never really delved into, including the specific features of plants, insects, birds, and marine life and how the surrounding environment connected to all of those. As for the 3-D printing model, I always knew that 3-D printers existed, but never got to actually see one or use one. This course gave me those opportunities and I was able to formulate a healthcare innovation with my group and have it printed out. Hopefully, our innovation becomes a reality one day and we can thank Dr. Greer and Jake for the motivation to do this project and turn it into something real that regular individuals can use to change their lives.

I couldn’t have been happier with the overall experience that I had in this course and cannot wait to take all the things I learned and utilize them in every future course and life endeavor possible.

 

Blog Post 2 – Lab Reflection

Working in the lab yesterday and essentially creating aspirin from scratch was a very interesting and eye-opening experience. It was a hands-on task that really had us utilize different topics we have covered in class, including experimental design, scientific uncertainty, and drug development. I’ve done a lot of experiments in labs, but not in this kind of setting, where we were working with real chemicals and intense safety precautions (the fume hood was especially new to me). Ultimately, it was a task that involved very meticulous concentration and incredible attention to detail, since there were a lot of precise measurements and timings that needed to be conducted. Being able to synthesize different ingredients to form aspirin was very satisfying, since it was a testament to the careful attention and effort that I displayed during the entire experiment.

The lab experience definitely connected to the major projects that we have been working on, the Bioblitz and 3D printing. Both emphasize the importance of following a procedure and using all the elements of the scientific method, as well as data analysis. Given all of the projects and experiments that I have worked on this semester really helped me understand the significance of using all of these things that we learned (scientific method, data analysis, media science literacy, experimental design, scientific uncertainty, drug development). Having the opportunity to conduct a very cool experiment in a real laboratory environment validated that.

https://link.springer.com/article/10.1007/s12038-007-0132-y

The authors of this article are scientists in the Department of Ecology and Evolution at Stony Brook University and the Department of Biotechnology and Genetic Engineering at the Jordan University of Science respectively. They describe how species that existed in the Old World through European transfer are still present today in the Americas. These plants have long contributed to the toxic environment that plants are surrounded by, which provides a historical perspective on why some plants are affected by a toxic natural environment. While the article does not go into detail about New York City specifically, it provides a historical outlook on particular species of plants and why the species of plants today still connect to those from centuries ago, in terms of toxicity.

https://www.sciencedirect.com/science/article/pii/S2221618914600226

The authors of this article are scientists at the Department of Biotechnology in Thiruvalluvar University in India. They describe how certain poisonous plants have beneficial medicinal values that can actually help the environment. By removing these poisonous plants from their surroundings, it helps decrease the toxicity levels and cause the surrounding natural environment to have less of an effect on the other plants. Since we are focusing on the toxicity of plants and the environment and how they affect the overall natural state of NYC parks, this article provides insight into how these poisonous plants can actually be a benefit. This leads into an interesting twist from the BioBlitz data and structure.

The authors of this article are scientists at the Department of Biochemistry at Ibrahim Badamasi Babangida University and the University of Nigeria. They discuss how certain poisonous plants that were harming the environment were tested on rats to see if the different plant features were indeed toxic. They tested the chloroform levels of different plants and found that the pants actually had at most a minimal effect on the health and behavior of rats. Being able to test out plants and their effect on the environment on animals provided insight on the extent of the harm that toxicity of plants causes. This article can be used to provide a unique perspective on how plants indeed affect certain aspects of the surrounding environment, more specifically animals. It is evident that animals are affected by the toxic plants, and although this was not tested for plants in NYC, it still does give a glimpse into the plants’ environmental impact.

HI Project Proposal

Thermal Compression Glove with Massaging Feature to Relieve Arthritis Pain

Group Members: Daniel Khaldarov, Felix Malamud, Mia Zaidi

The healthcare problem that we would like to address is rheumatoid arthritis pains in the hands. Due to the fact that rheumatoid arthritis is a serious issue affecting over 1.5 million people in the United States, we wanted to propose an idea for the most effective form of treatment possible. Very frequently, some kind of drugs or supplements are used in an attempt to deal with arthritis, but this can cause further health complications and some patients prefer a non-pharmaceutical alternative. Products have been made using heat therapy, compression, as well as massaging, to treat pains in the hands due to rheumatoid arthritis. There is an abundance of scientific literature that shows that heat and compression has a beneficial effect on people suffering from rheumatoid arthritis. According to an article in the PloS One Journal entitled, “Defining Immunological Impact and Therapeutic Benefit of Mild Heating in a Murine Model of Arthritis Evidence,” heat treatment significantly reduces inflammation in joints (Lee 2015). Although there was little improvement in hand function with the use of therapy gloves, pain was substantially reduced (Nasir 2014). Our healthcare innovation aims to increase the effectiveness in pain relief by combining these forms of therapy (which current available products fail to do) into one wearable product. Our idea is a thermal compression glove with a massage feature. The massage feature would use vibration and target specific pressure points that are associated with pain relief. This type of innovation is much more convenient as it is an all-in-one form of treatment that requires no prescription and can be worn without interfering with a person’s day-to-day activities. In terms of commercial success, such a thermal compression glove can be used by anyone that wants an easy and effective way to treat rheumatoid arthritis. Those that deal with rheumatoid arthritis often, or even people who have early stages of it, would definitely find this product incredibly beneficial. We feel that there has to be a better way to deal with this issue and our innovation would be the right tool for the job, due to its multi-functionality, convenience, and effectiveness.

Wei Sun, along with the other scientists, are based in Drexel University in Philadelphia. Sun, Ph.D. is a chair professor at the Department of Mechanical Engineering and Mechanics, as well as a distinguished professor at the Department of Mechanical Engineering in Tsinghua University, Beijing, China. In this article, the scientists discuss a study that they conducted about a method of 3D printing for Hela cells and gelatin/alginate/fibrinogen hydrogels to construct in vitro cervical tumor models. They compared the 3D and 2D results that Hela cells revealed. More aspects of tumor evolution and Hela cells were visible with the 3D model than those in 2D culture. These new biological characteristics from the printed 3D tumor models in vitro, as well as the novel 3D cell printing technology, may help the evolution of 3D cancer study. This article can be used to provide a specific type of cell tested for 3D models. Knowing how different types of cells are treated through 3D modeling gives a broader perspective on the impact of showing tumors through such a technique.

The research was led by Martin Nowak, who is the Director of the Program for Evolutionary Dynamics and Professor of Mathematics and Biology at Harvard University, and Bartlomej Waclaw, who is an RSE Research Fellow at the University of Edinburgh. The scientists describe a new model that was developed for tumor evolution that shows how short-range dispersal and cell turnover can account for rapid cell mixing inside the tumor. Their model not only provides insights into spatial and temporal aspects of tumor growth, but also suggests that targeting short-range cellular migratory activity could have marked effects on tumor growth rates. This article can be used for evidence as to why a new model is necessary to be able to fully detect key aspects of tumors that could not have been previously discovered.

BioBlitz Worksheet

Team Members: 

Felix Malamud

Daniel Khaldarov

1) What is the final version of the question you are interested in asking?

How does the population of toxic plants in Inwood Hill Park compare with that in other major parks (with a certain minimum square footage) in NYC?

2) List some keywords to use when searching for related scientific literature. Be specific!

Key words: Toxic plants population, NYC parks 

3) Where will your data come from? Do you need to collect new data? Please describe.

Data will primarily come from the Bioblitz INaturalist database. The Bioblitz database can provide information about where poison ivy has been spotted in the major parks of NYC in addition to Inwood Hill Park.

3) What will you be measuring or comparing? What are the dependent and independent variables?

We will be comparing the population of toxic plants in Inwood Hill Park to that of other major parks in NYC. The independent variable is the location of the toxic plants, and the dependent variable is the population of the toxic plants. 

4) Please make a list of your methods. If you are using existing BioBlitz data, you do not need to describe those data collection methods on this worksheet, but you do need to describe how you are extracting the relevant data from the entire BioBlitz data set.

With existing Bioblitz data collected through INaturalist, we will first identify what toxic plants inhabit Inwood Hill Park by looking through the data collected under the “Plants>Species” section of the database and researching the species to determine their toxicity. Then we will identify the population of these toxic plants identified in Inwood Hill Park and other major parks in NYC.

5) Why is this question interesting to you? Why should others care about this topic?

Knowing if Inwood Hill Park or other parks in NYC have an abnormally high or low population of toxic plants can indicate whether or not there is a need to regulate the growth of such toxic plants in certain areas to maintain a healthy environment.

3D Printed Models of Cancerous Tumors

One of the biggest issues when treating cancerous tumors is that these tumors can grow and spread in an unpredictable manner. There have been cases where patients that were treated for cancer through radiation and chemotherapy saw the tumors continue to spread without even knowing it. Being able to have 3d-printed models of these tumors will aid in the discovery of new anti–cancer drugs and better understanding of how tumors develop, grow, and spread. It’s an example of how 3D printing can also help in medical research and the outcome of complex operations and especially difficult cases. This is important to me because it is a topic that I briefly touched upon during my Hot Topic presentation, which focused on how artificial intelligence is able to detect evolution of tumors and repeating patterns within these tumors. Such an innovation that can be done through 3D printing will help in visualizing the way cancerous tumors can be detected and properly treated. It’s also a topic that I have a deep personal interest in, which is why I went in that direction.

Blog Entry 1

Reading through numerous popular reports about scientific and healthcare innovations, it is obvious that authors portray their writing differently, depending on the type of discovery, how the author wants to appeal to the audience, and knowledge of the topic.

If I had to author an article in the NY Times or a comparable periodical on a scientific paper, I would make sure that the content both caters to a broader audience and educates readers at an appropriate level. I would make sure to state the main points discussed in the scientific paper, but expand on them in a little more detail. This way, readers will clearly understand what the paper is about, while also gaining more insight on the paper’s synopsis, through graphs, data, and quotes from the scientists and researchers involved.

Other than simplifying scientific jargon, including data from the scientific paper and any vital details not in the abstract, introduction, or conclusion will make the popular media report a good representation of the scientific research.

When writing about science, the authors should definitely know what they are writing about. They need to thoroughly read the scientific research to be able to paraphrase and simplify the paper for a popular media report. From what I have noticed, a lot of authors do not include data or any other specific findings in their report. That is something the author should absolutely touch on to make the report more educational.

Looking at all of the presentations, it surprised me that the degree of detail and scientific jargon in the reports were mixed. I would have expected the authors to know the research and include that important information. However, based on the source of the popular reports, I could see why some authors write in the style that they do. Regardless of how much information the author includes, the ultimate goal is to appeal to as broad of an audience as possible.

Paraphrase Exercise

School nurses around the United States face a common dilemma, regarding treatment of certain allergic reactions. Health care providers are recommending strict guidelines of emergency action for their patients. These plans, however, conflict with those provided by the current school district and the American Academy of Asthma, Allergy, and Immunology. Such inconsistencies are likely to result in confusion between the health care providers, the school district, and the American Academy of Asthma, Allergy, and Immunology. But the bigger issue is that delaying proper treatment can potentially increase the risk of anaphylaxis. Several studies illustrate how safety concerns have arisen due to such delays or severe lack of treatment of epinephrine reactions (Boyce et al., 2010; Carlisle et al., 2010; Fleischer et al., 2012; Nowak-Wegrzyn, 2012b). To ensure the safety and best possible care of the students, school nurses should work together with the parents and health care providers to formulate the proper guidelines.
