We will examine the positive and negative controls in the milestone article of the Nobel Laureates. The article shows us one of the best examples of how to use positive and negative controls in life-science experiments. We will compare a total of eight figure panels. And we will learn important lessons from them, for designing experiments and for reading figures. This episode will be Part 1 of a summary of control experiments.
Here are the links to the Milestone Article 1 (Immunity, 2005) by the Laureates, Dr. Katalin Karikó & Dr. Drew Weissman of the Nobel Prize in Physiology or Medicine 2023.

What does it take to prepare a single lecture? In this episode, I will talk about months-long process for crafting a lecture on how to read clinical papers. I am passionate about teaching this foundational skill. The preparation includes choosing a paper that is best fit for the interest of the student body. It also includes making presentation slides tailor-made for the specific paper. I hope this episode is helpful for both fellow instructors and students. This episode = mini-series: training-2. (My email is active. But my website is under construction. Please wait for a while. Thank you for the patience!)…
I have set up a training program for the postdoctoral researchers (postdocs) in my home department. Today, I would like to talk about: how and why I have done it, what we do in the program and what (positive!) feedback that I received. This episode might help you if you are a student looking for training opportunities or if you are a mentor who is already guiding your immediate trainees. This episode = mini-series: training-1.

1 58. Paragraph 1 of Introduction, written by Nobel Laureates: meaning of each sentence therein 16:51
Let’s read the first paragraph of the Introduction section in a paper written by the Nobel Laureates. Specifically, we will read each sentence in the paragraph, and think about the meaning and the role of each sentence. One key point is that the structural components of the Abstract will help us understand the paragraphs and sentences of the Introduction. We are reading the paper written by Dr. Katalin Karikó & Dr. Drew Weissman, that led to the Nobel Prize in Physiology or Medicine 2023. We call it the Milestone Article 1. Here are two sets of links related to the paper. Milestone Article 1: - “Suppression of RNA recognition by Toll-like receptors: the impact of nucleoside modification and the evolutionary origin of RNA” by Karikó, Buckstein, Ni & Weissman.

The Introduction section of a life-science paper tells the main story, sometimes even multiple related ones. But without helpful subheadings, understanding its core points can be challenging. Then, how do we effectively read Introduction paragraphs to understand the section? We will talk about it today, and we will keep reading one of the best papers as our example. We are reading the paper written by Dr. Katalin Karikó & Dr. Drew Weissman, that led to the Nobel Prize in Physiology or Medicine 2023. We call it the Milestone Article 1. Here are two sets of links related to the paper.

In combination with the last episode, we will talk about an introduction to how to read the Introduction section. With these two episodes, we will be ready to analyze the content details, from the next episode. We are reading the paper written by Dr. Katalin Karikó & Dr. Drew Weissman, that led to the Nobel Prize in Physiology or Medicine 2023. We call it the Milestone Article 1. Here are two sets of links related to the paper. Milestone Article 1: - “Suppression of RNA recognition by Toll-like receptors: the impact of nucleoside modification and the evolutionary origin of RNA” by Karikó, Buckstein, Ni & Weissman.

Sub-sections and subheadings will be helpful. The Methods and the Results sections of life-science papers are divided into sub-sections. And the sub-sections will have subheadings, i.e., the titles that serve as signposts of the sub-sections. How about the Introduction section? What would this finding mean to us, the readers? We will talk about them by scanning the Introduction of a paper written by Dr. Katalin Karikó & Dr. Drew Weissman, that led to the Nobel Prize in Physiology or Medicine 2023. We call it the Milestone Article 1. Here are two sets of links related to the paper. Milestone Article 1: - “Suppression of RNA recognition by Toll-like receptors: the impact of nucleoside modification and the evolutionary origin of RNA” by Karikó, Buckstein, Ni & Weissman.

The single-sentence rule for understanding research paper Introductions. Have you thought about what the Introduction section of a life-science paper really does? In this episode, we will address that question and discuss a simple rule. We will share a single sentence that encapsulates the entire role of the Introduction. It will make it easy to grasp the authors' intention and the paper’s core logic. Hint: it is related to the key trio in the Abstract: the "Background-Known-Unknown" trio from Episode #53. This episode = mini-series: reading-34. (My email is active. But my website is under construction. Please wait for a while. Thank you for the patience!)…
In today’s episode, we will learn which structural components will be minimally essential for an abstract, and which will be additionally necessary for a well-written abstract. These are the abstracts of primary research papers in life sciences, both in clinical- and basic-science fields. There are very many variations in the structures of published abstracts. Why do we want to discuss the above topic? This is because understanding the essential components of abstracts will help us anticipate key information and understand the content more effectively! This episode = mini-series: reading-33. (My email is active. But my website is under construction. Please wait for a while. Thank you for the patience!)…
Let’s talk about an excellent abstract that I read this week. It was so well written, and I was so excited to read it that I wanted to talk about it with you today. The beauty of it is that the first 3 structural components guide us through the authors’ intention and question very clearly. But there was also a little twist to the structure: we will talk about it, too. The abstract that we talked about today was from the following paper: “A meta-analysis of technology use and cognitive aging” Benge & Scullin, Nature Human Behaviour, 2025 “Online ahead of print” (thus, no volume number or page numbers) as of the date of this episode upload. PubMed link: https://pubmed.ncbi.nlm.nih.gov/40229575/ Journal link: https://doi.org/10.1038/s41562-025-02159-9 We can read its abstract on either of the above websites. Unfortunately, the other parts of the paper are subscription-based. So, they are accessible, if you or your institutions have a subscription to the journal. This episode = mini-series: reading-32. (My email is active. But my website is under construction. Please wait for a while. Thank you for the patience!)…
My students selected a paper to read in a journal club. The abstract (and the rest of the paper) was not written well. The abstract gave us two precious lessons. Lesson 1: Good structural organization will help the readers understand the content. Lesson 2: Abstracts of peer-reviewed papers can be disorganized. I hope you learn them in this episode, too! This episode = mini-series: reading-31. (My email is active. But my website is under construction. Please wait for a while. Thank you for the patience!)…
We have reached 50 episodes! Thank you for listening. Today, we will briefly talk about how I have kept sustainable podcasting so far. The most important thing may be that I have set my goal simple and single: It is to create high-quality content for you. That’s it. Here are links to two sources of podcast statistics that I mentioned in the episode. https://www.amplifimedia.com/blogstein-1/lyspqop3ylro9a2t7y2de820uwkgwx https://podcastindex.org/stats (My email is active.

1 49. Another well-crafted logic loop in Abstract by Nobel Laureates (mini-series: reading-30) 18:26
We will talk about the second of the two, well-crafted loops of logic, in the Abstract of a paper written by the Nobel Prize Laureates. Not all abstracts have this second loop. But when it is present, it gives a better overview of the impact of the presented work. We can find one of the best examples in our Abstract. We are reading the paper written by the Laureates, Dr. Katalin Karikó & Dr. Drew Weissman, that led to the Nobel Prize in Physiology or Medicine 2023. We call it the Milestone Article 1. Here are two sets of links related to the paper.

I can visualize two well-crafted loops of logic, in the Abstract of a paper written by the Nobel Prize Laureates. Can you? We will talk about one of them in today’s episode. Such a loop, together with a linear progression, highlights the authors’ clear and logical thought process. We are reading the paper written by the Laureates, Dr. Katalin Karikó & Dr. Drew Weissman, that led to the Nobel Prize in Physiology or Medicine 2023. We call it the Milestone Article 1.

Let's analyze a single sentence in the Abstract of an impressive paper. It is the paper that led to the 2023 Nobel Prize in Physiology or Medicine. This is the paper that we call the milestone article 1 (Please see below for details). We will analyze the second sentence. Why is this sentence important? We will discuss four of my approaches to see that this sentence is important, beautiful and helpful for readers outside the field. It is fun to spend one episode for just a single sentence, and think deep about how it reveals the authors' logic. Here are two sets of links related to the paper written by the Laureates, Dr. Katalin Karikó & Dr. Drew Weissman of the Nobel Prize in Physiology or Medicine 2023.

1 46. Let’s analyze the Abstract of a paper written by Nobel Laureates (mini-series: reading-27) 27:59
Today, we will analyze the Abstract of an impressive paper. It is the paper that led to the 2023 Nobel Prize in Physiology or Medicine. This is the paper that we call the milestone article 1. We will have two essential pre-analysis sub-steps, and then we will analyze each sentence. During this analysis, we will read each sentence of the Abstract, examine the role of each sentence, and assign each sentence to a structural component, so that we will be able to understand the authors’ intention for each sentence. Here are two sets of links mentioned in this episode. All are related to the Laureates, Dr. Katalin Karikó & Dr. Drew Weissman of the Nobel Prize in Physiology or Medicine 2023.

Today, we will take a significant step towards understanding the 2023 Nobel Prize in Physiology or Medicine. We will read the Abstract of the Laureates’ most important paper that led to the Nobel Prize. This is the paper that we call the milestone article 1. We will have two essential pre-reading sub-steps, and then we will conduct the initial readings. These sub-steps will set the stage for a more in-depth exploration in the next episode. Here are two sets of links mentioned in this episode. All are related to the Laureates, Dr. Katalin Karikó & Dr. Drew Weissman of the Nobel Prize in Physiology or Medicine 2023.

Today’s episode is part 1. We will discuss the first two phases of my experience. My overall goal of the two-part episodes is to highlight the unique roles that textbooks play, different from those of primary research papers. Knowing these different purposes will help us read textbooks more effectively. (My email is active. But my website is under construction. Please wait for a while. Thank you for the patience!)…

“Should I exclude irrelevant experiences from my academic CV?” This is a question that students often ask. In this episode, I would like to give you my thoughts about this question. In general, there is a way of creating a comprehensive CV: it will show that you have unique experiences, and you are a careful and a thoughtful writer. The key would be for you to be proud of what you did in the past. I hope that this discussion will be useful for you. (My email is active. But my website is under construction.

“Should my CV be short or long, when I apply for a research assistant position in a college/university lab?” This is a question that students often ask. In this episode, I would like to give you my thoughts about this question. The content in a CV depends on the person’s career stage. But I have one common viewpoint for CVs at all stages. I would like to view the descriptions in the CV, during and after the undergraduate education, as the defining statements of the person. My thoughts about today’s question will be related to this viewpoint. At the same time, I agree that different professors and different students may have opinions different from mine. Let’s discuss them and share diverse perspectives, so that our thoughts will become deeper. (My email is active. But my website is under construction. Please wait for a while.

How do top-tier scientific journals, like Nature, make sure their abstracts are clear and impactful? In today’s episode, we will identify the eight key components that make those abstracts effective, by naming the components in our own words, and clarifying their roles and order. Our system was inspired by the Nature document for the Abstract guidelines that we discussed in the Episode #38.

What is the best way to learn how to read the Abstract of a scientific paper? In my view, the best way is to learn how the Abstract is structured in any paper. Today, we will learn it, by reading a very short document. It is a one-page document that describes the Abstract guidelines, provided by the journal, Nature. Here is the URL that brings you directly to the Nature document: https://www.nature.com/documents/nature-summary-paragraph.pdf Here is the URL of the webpage for the Instructions for Authors by Nature.

We will keep analyzing the specific positive controls that the Nobel Laureates used in their milestone article 1 that led to the Nobel Prize. We will examine the four positive controls in the third figure of this paper, and in other figures as well. Those positive controls did not necessarily show positive responses in multiple figures. We will observe that positive controls can show variable behaviors in a paper. We will also discuss how a modified definition of positive controls will be helpful for understanding them.

1 20. Detective work of troubleshooting a puzzling experiment: negative control as a guide (mini-series: reading-13) 23:20
We will experience the fascinating world of scientific troubleshooting. In this episode, we will revisit a life-science experiment where researchers aimed to see if a specific chemical compound could enhance a particular function in cultured cells. Their plan seemed straightforward - a pilot experiment with a positive control (active compound) and a negative control (inactive compound). They wanted to confirm everything worked as expected. But the results were strange! Both the positive and negative controls showed unexpectedly high cell function, leaving the researchers scratching their heads. Join us as we explore the initial troubleshooting steps. Help us by showing your idea: where in the protocol the problem could be hiding. Stay tuned for the next episode where we continue this exciting discussion. This is Part 13 of the reading mini-series "Let’s read a paper written by Nobel Prize Laureates, 2023."

1 18. In-depth analysis of negative controls: using Nobel Laureates’ as example (mini-series: reading-11) 30:11
Today's focus: negative controls. In life-science experiments, negative controls play critical roles. In my view, they are more important than the positive controls! They form such a rich topic that we will spend at least a few episodes on discussing them. Today, we introduce basic aspects: 1) what the negative controls do in life-science experiments, 2) our practical definition by modifying the typical and ideal one, 3) how the negative control was used in our milestone graph (Fig. 3D of milestone article 1 by the Laureates of the Nobel Prize in Physiology or Medicine 2023), and 4) two critical assumptions for negative controls to work properly.
