Shelly Wu, Week 1

I started work this past Monday, June 11th. On the first day, I arrived at Hayden Hall, where the lab is located, a little bit earlier than Dr. Plante (My PI) did. I got into the building when he arrived, and we started working right away. He told me about a change in my project. My project is a based on the research of Liz Coward, one of Dr. Plante’s former PhD students. We planned to extract mineralized-carbon in soil samples, and then conduct thermal analysis on the residues to figure out the soil composition. However, as Dr. Plante was emailing Liz to settle on my project, Liz told him that she kept the residue samples of her extractions in the lab so that I did not have to conduct the extractions again. Dr. Plante decided that I could conduct a different kind of extraction, hot water extraction (HWE), and yield a new set of data. After everyone arrived, he introduced me to other people in the lab. Gabe is an undergrad from the University of Minnesota, and he works with Liz (not Liz Coward), a postdoc, on biochar. Kyle is an undergrad from UPenn working on black soils. I will be collaborating with Kyle for the first part of my project because we both need to conduct HWE. After that, Dr. Plante gave me some more papers to read. He encouraged me to read every day in order to have a good understanding of the field and my own project. In the afternoon, we spent some time going through the questions I had for the readings, and I wrapped up my day at around 4:30 p.m.

On Tuesday, I started going through the soil residue samples that Liz left behind. My job was to record the amount of residue left in each sample so that I could pick some samples for my project. It was tedious work. My head hurt after going through the 160 vials when I finished work that day. From this, I learned that science is fun, but there are tedious processes, too. The key to getting good results is to do every step meticulously, even the tedious ones.

On Wednesday, I attended the lunch meeting for undergrads doing research in Hayden over the summer. We introduced what we did in the past week, and talked about ways to approach readings and access to the databases in UPenn libraries. In the afternoon, Kyle and I went to the Biochemistry Library to find articles on HWE. Our task was to figure out the ratios of soil and water that other people used in their projects and create a protocol for our own HWE.

We spent Thursday reading papers and working on our protocol. On Friday, we started preparing the trash soil samples for HWE.

Next week, Kyle and I will each conduct HWE twice on the trash soil samples to make sure that the protocol we made is feasible. Then we will conduct HWE on our own soil samples.

My first week in the lab is fun. I learned so many things about doing research, not only weighing samples and pipetting solutions. I look forward to the following weeks.

    Sounds like an awesome first week! And yes, as you are learning, research can be monotonous and repetitive at times but it pays to be meticulous! Very cool that you are helping develop the protocol for the HWE - can't wait to hear about it tomorrow!

Evan Bradley, Week 3 at the Missouri Orthopaedic Institute

As mentioned in my previous blog, I have been awaiting ligament, menisci, and cartilage tissue from a canine or human knee joint for (interleukin) IL-1B tissue culture. IL-1B is an inflammatory cytokine that has been proven to increase rates of tissue degeneration and osteoarthritis development in the Thompson Lab. Dr. Stoker wants me to experiment with different types of knee tissues in a co-culture with varying levels of this cytokine to determine its effects on the entire knee joint. This co-culture uses an insert permeable to the media to separate the two tissue samples from physical contact, while allowing them to share the same media. This creates an extremely accurate model for knee tissues in their native environment due to their exposure to the same synovial fluid in the joint. This model would then be treated with the IL-1B and cultured for 21 days. During these 21 days, the media would be collected every three days for biomarker evaluation at the end of the stu...

Kylie Heering, Week 2 at the Goldstein Lab

We started off our week with a congratulatory acai bowl trip to celebrate Preston’s acceptance into a training grant program. Acai bowls in California top Playa Bowls (no question about it). From what I can tell, its a pretty huge honor to be recognized by this grant, but he’s really humble about it. On Monday, Preston and I decided that testing antibodies that have never been tested on prostate epithelial cells before would be a good objective for my first Western blot on my own. We needed to probe for ASCT2, a glutamine transporter, and GLS in order to determine if their corresponding antibodies are functional. Antibodies are crucial for Western blots because they bind to the protein of interest (POI), allowing for us to qualify its expression after imaging. As such, Preston wanted to make sure they worked by probing for ASCT2 and GLS on three different cell lines. Cell lines are commercially purchased human cells that have been immortalized (modified to grow indefinitely) by telome...

Daniel Cheng, In My Own Room

I had no idea that Pennsylvania is this wide. Within the first hour, my train had reached Philly. But to Pittsburgh, it took another seven. Even before I stepped foot into the Search-Based Planning Lab, I was waylaid by some anxious news. The PhD student assigned to be my mentor, Dhruv, texted me that he, Dr. Likhachev, and most of the lab would be out of town for the entire week. So that was that. Fortunately, it was my first week, the week to be spent learning new material, and Dhruv provided me with plenty to digest. I already had ROS (Robot Operating System) installed, so I looked towards the tutorials that ROS provided. I copied commands into my Linux laptop's terminal to run ROS features. I learned the basic structure of ROS: packages, services and clients, publishers and subscribers, messages, nodes, and topics (which nodes communicate messages over). There was one simple yet interesting program I came across in the tutorials called turtlesim, for which using only 2 comm...
