Charlotte Heacock - Week Two



This week was very busy. I started out each day watches two or three fin print videos. I have been seeing a lot of brown-banded bamboo sharks and lemon sharks and I even saw a couple of green sea turtles. I spent three afternoons in the wet lab processing my vertebrae and so far I have managed to get through about half of the samples. After I finish all of them, my next step will be to bleach and bake them.  The other two afternoons I spent collecting data for a spreadsheet on the life history of guitarfish. I have about fifty-five species to get through, many of which are data deficient.

After the spreadsheet is as complete as it can get with the data that is already available, I will finish aging the vertebra and getting the DNA samples back so it will hopefully fill in some of the blanks and provide data about this fish that has not yet been provided. I also got to help another student feed the epaulette sharks this week. She is working on determining the temperature preference for these sharks.  This was extremely exciting for me because they are one of my favorite species, they can survive out of water for about three hours and have the ability to use their fins to walk back into the water. One of the PI’s has also got me setting up a community science database project for sightings of porcupine stingrays because they are also fairly data different so the more information about their location or presence, the better chance we have of learning more about them. On Friday we also had a dead juvenile scalloped hammerhead and a whip ray brought in most likely left on the beach from bi-catch by a fisherman. We were able to take a fin clip for DNA analysis and freeze the specimens for further research. I’m looking forward to my weekend so that I can explore the city some more. I am going to a waterfall and swimming hole with some of the students at my lab on Saturday and we are going to have an authentic Aussie BBQ!

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...

Alan - First Week at UCSF

Hi Everyone! After arriving in San Francisco last Sunday, I spent this past week settling into the downtown Berkeley apartment that I’ll be sharing with Rohit for the next couple of months, as well as learning my way around the Roy lab at UCSF. First day at the lab was really exciting. Here are a couple pictures of the Mission Bay campus, which was completed just a few years ago. Everything is super new and modern, and there’s still construction for other buildings going on around the campus. Most of the people who work at the Mission Bay campus are either professional researchers or doctors/nurses for the nearby hospital. The graduate students take most of their classes at the original Parnassus campus (where Maya is). I work in Byers Hall, which is connected to Genentech Hall and a short walk down the block from the shuttle stop. There are three other volunteers working for the Roy lab this summer – Kimmai, David, and Pujita, who are all undergrad college students...

Wendy Li, Week 1

It is now early July and I have finally started my lab work. I arrived there at about 9 am on the very first day of my lab and found out that there were only two people in the office—Alex, a graduate student in engineering school, and me. “There should be more people in the office, but most of them went to a vacuum workshop today.” Alex told me. My work officially started at 10:30 am when my post doctor Subarna came to the lab. Familiarizing me with all the facilities in lab, Subarna first gave me a lab tour. Meanwhile, he showed me all the basic operations with vacuum chamber, ellipsometer, as well as the spin coater. During the rest of this past week, I was in the process of making my own films. I learned to cut Si wafer into 1*1 cm pieces and clean the surface of these Si wafer with duster and plasma which can effectively clean up all the extra organic particles from the wafer. Further, I prepared 10 percent polystyrene (PS 8000) toluene solution as the material for spin coating. ...
