  • Received confirmation that RNA is in line for QAQC

  • Read manual for Nikon compound scope, setup for making embryology preservation slides & taking photos

02-SEP-2024

  • Submitted Sample Form to Azenta

  • Writing & editing chapter 1 methods

28-AUG-2024

  • Received email confirmation of receipt of RNA at Azenta!

27-AUG-2024

  • Shipped Total RNA to Azenta in 96 well plate on ~16lbs of dry ice, FedEx Priority Overnight from SeaTac FedEx Office Ship Center

  • Tracking #: 278809181237

15-AUG-2024

  • Met with Jefferey Kim of Azenta GeneWiz

    • Got a quote for 60 TotalRNA-seq with PolyA selection, 20M reads per sample

    • For Total RNA in nuclease-free water on dry ice, need 100ng of Total RNA… so if I have 10ng/uL in 30 uL… that means there is 300 ng of Total RNA in that sample. Jeff said 10ng/uL is usually the cutoff. I can send Total eluted RNA in 30uL without normalizing or Nanodropping… they will run RIN scores when they receive the samples. I just have to extract and Qubit!

    • 23-28 business days turnaround time

    • With discount, price per sample is $98.50! Total cost is $5,910.00 in quote :D

  • met with Kip and made calendar of assignments due

  • changed out filters on seawater filter rack in PBB

    To measure impacts of microplastic exposure on anemone size, oral disk diameters were calculated using the average of two perpendicular measurements across the oral surface intersecting at the mouth. Measurements were made using Image J software (Rasband 19972018) with digital photographs of each anemone …. - Beck, 2022 WWU Dissertation

  • How do we get scaled images of the oral disc?

21-MAR-2024

  • spent nearly all day drying an edge of each petri dish, and gluing bee-tags to them with superglue, then letting it dry by floating the petri dish on a floating rack in the seatable. Took all day..

  • swapped anemones from upper seatable to lower, changed water in upper, and letting it come down to temp (when doing water changes, cannot do it directly, as header water is at room temp and seatables are at 10C…. How will I deal with this during the experiment when each anemone is in a 200mL jar and I’ll be doing water changes every other day

    # 72 anemones each in 200mL volume... how much volume I will need to change every other day
ml <- 72*200
print(ml)
    [1] 14400
    # how much of each treatment (seawater vs. leachate)
ml/2
    [1] 7200

    The amount of microplastic may be our limiting factor for how long the exposure is.

We have 3 grams of each microplastic type

To make a batch of leachate according to the Saliu Lab protocol, we have 250 mg of microplastic.

# 3 grams is 3000 mg, how many batches of leachate will each microplastic type make?
3000/250
[1] 12

12 batches… that’s a lot, and should be plenty since it is a highly concentrated amount that will be diluted.

How will it be diluted?

20-MAR-2024

  • cleaned anemones by picking rocks and debris from them, and squirting with chilled seawater from a lab squeezie bottle. Two were ‘escapees’, one was fully out of the petri dish! I popped it back in. The ones that are nudging around the edge/lip of the petri dish I use my finger to just push their pedal disc back inside the dish… not sure what I can use to deter them from escape that won’t expose them to more chemicals (i.e. tape ahdesive, etc.)

22-FEB-2024

  • Roberts Lab meeting, received feedback on anemone research proposal: suggested I do initial response curves to find at what temp A. elegantissima experience stress, at what microplastic leachate concentration do they experience stress? Measure response variables ‘quickly’ by respirometry and PAM. Can I make the single stress, multiple response variable, the first chapter of the Master’s thesis? Then, two stressors together with `omics response variables (once we find the inflection points of stress) can be the second chapter…. Ariana pointed out that the paper reviewers are going to want to know why I chose certain concentrations of microplastic leachate. I have to justify that by doing a response curve first. Learned about Roberts Lab pubathon.

  • Took FireSting O2 to IT to try and get correct drivers on mariscos ruggedized laptop to run the program…

  • pyroscience FireStingO2 deemed ‘dead’ by IT specialist Michael Shriver… the unit won’t connect. I sent the following to the Walz product support team Todd Kana (kana@bayinstruments.com) & Erich Keim (ekeim@walz.com):

    Good afternoon  Erich and Todd, 

    I’m a graduate student researcher in the Padilla-Gamino Lab at the University of Washington, and I’m working with a Walz Mini PAM-II and FireStingO2 oxygen meter that our lab purchased from you as a set. The instrument was previously used by Miranda Roethler, who passed your contact information on to me. 

    The FireStingO2 oxygen meter is not powering up, and won’t connect to any computer that we’ve tried it on. It was just with our IT specialist for the last few hours (he was attempting to get it to connect by downloading old drivers), and he shared that the laser-cut `FiresStingO2` light on the instrument would ‘pulse’ red and then remain off. He deemed the instrument ‘dead’… 

    This instrument has only been used a handful of times, and it has been kept in good condition (not dropped, or been exposed/submerged in water etc.). 

    Have you had this issue before? If so, are there any solutions you can help provide?

    Kindy, 

    - Sarah Tanja

  • pyroscience FireStingO2 only works on Windows 10!?

  • Ammonia levels in PBB header tank are at 1ppm, something green is growing in there. When was the last time we checked that the UV sterilizer was working? I should change out all the filters on that seawater purification rig, and the reverse osmosis deionized water filter cascade.

  • There is algae growing in the PBB header/holding tank

  • Met with Kip, Added Kip to WDFW scientific collection permit

  • 9 permit locations!

  • Messed around with mapping the collection sites, from R Graph Gallery, https://r-graph-gallery.com/180-change-background-in-leaflet-map.html

  • Writing your resume for federal job webinar

    • schedule A: disability accommodation

    • Federal hiring resume, there is no page limit

    • The resume gets you to the hiring manager, show in the resume that you qualify before it goes to a hiring manager

    • hiring managers in Federal hiring do not click on links (github, linkedIn, etc.) they won’t be viewed…

    • ‘Your resume is the movie trailer…’ Highlight the level of complexity of your work

    • Itemize how how manage something, on top of listing your role… you have to explain what you did in that role. The role ‘president of xx’ doesn’t translate to the person reviewing the resume knowing what you can do… leave nothing to the imagination. Be explicit.

    • Spoken presentations: how many presentations you have given, what & when

    • The first person that looks at your resume is a human resources specialist, not a scientist!

    • show that you are an ‘innovator’ and that when you see a problem, you take initiative to fix it.

    • where you go, people are impacted positively, there is recognition, things change or improve, things get better, you save money, you meet deadlines, you bring about conflict resolution.

    • the cover letter is not used to qualify you, ONLY THE RESUME!

    • Vet team to assist navigating federal hiring process: fedshirevets@opm.gov

    • You get shuttled into qualified, well-qualified, best-qualified. Qualifying doesn’t mean that you get referred to the hiring manager… you can qualify but not get referred to the hiring manager. You can be referred, but not get an interview.

“Total RNA was extracted using the Duet DNA/RNA Miniprep Plus Kit (Zymo Research, Irvine, CA, USA, Cat #D7003) with modifications to the manufacturer’s sample preparation steps, as described here. Sterile clippers were used to remove an approximately 1-cm diameter region from the coral tissue. The tissue clipping was placed in 500 μL of DNA/RNA shield (Zymo Cat #R1100-50) with 0.5 mm glass beads (Fisher Scientific Cat #15-340-152) and homogenized by vortexing for 1 minute. The supernatant (450 μl) was transferred to a new tube and centrifuged at 9000 rcf for 3 min to remove any debris. The supernatant (300 μl) was mixed with 30 μl of Proteinase K (Zymo Cat #D3001-2-20) digestion buffer and 15 μl of Proteinase K in a new tube using a brief vortex step. Equal volume of Zymo lysis buffer (Zymo Cat #D7001-1-200) was added (345 μl) and extraction was completed as outlined in the manufacturer’s protocol. RNA concentration was quantified using the Qubit RNA Broad Range kit (Invitrogen Cat #Q10211) and integrity was assayed with an Agilent TapeStation 4200 system and the RNA Integrity Number (RIN) values ranged from 7.0–8.9. RNA libraries were prepared using the Zymo-Seq RiboFree Total RNA Library Kit (Zymo Cat #R3000) according to the manufacturer’s instructions, starting with 125 ng of RNA as input. Prepared libraries were sent to Zymo Research Corporation for sequencing using the Illumina HiSeq for paired end sequencing (2 × 100 base pairs [bp]).” - Wong & Putnam 2022 (Wong and Putnam 2022)

24-AUG-2023

  • Trial with 2 ambient samples of modified extraction protocol and RNA Clean & Concentrator. I did 2 samples because I had a kit that had 2 preps left over. Most of the time spent is in lab bench sterilizing, prepping, labelling, getting ice! Which takes literally a 30 minute hike across campus… But I started at 930AM and finished with Qubit in the FTR Roberts Lab by 4PM. With 2 samples! Extractions take ALL DAY.

17-AUG-2023

  • Are we sure we want to try TriZol for RNA? It isn’t a phenol-free kit like the Quick DNA/RNA Miniprep, and we have RNA, we just need to purify it. Tomorrow lets run all eluted RNA through RNA Clean & Concentrator, and check it on Nanodrop! LFG.

    How will attending the WSN meeting help you advance your career as a naturalist and/or scientist (75 words max)?

    Attending WSN would be my first opportunity to share my Masters thesis with the scientific community. As an undergrad, I had a bad first conference experience where I was ridiculed for not having results in a methods poster. I hope to attend WSN because its reputation as a welcoming environment for early-career scientists is the kind of scientific community I wish to be a part of and perpetuate in my own career.

    What are you working on to improve diversity, equity and inclusion in your community (75 words max)? (Examples may relate to personal identify, interest, experience, etc.)

    I recently took part of the Identity, Belonging, and Inquiry in Science Program, and received special training to mentor students from diverse backgrounds. My mentee worked hard to complete research that she will present at the upcoming SACNAS conference, and I couldn’t be more proud. The training gave me confidence to take on another mentee, this time a Capstone student. Mentorship is a key part of DEI efforts that I find extremely rewarding.

16-AUG-2023

  • asked JPG to buy benchtop UV Sterilizer for me & Callum, got approval! Purchased by Kat same day :D

  • NMDS (non-metric multidimensional scaling) ordination plots

  • walked with Callum, plan to ask JPG to buy Qubit too!

  • Made some taxonomy bar plots and heatmap dendrograms… still working to understand what they mean but they don’t look like there is separation between treatments. Haven’t gotten any pvalues yet from the composition analyses…

  • Wondering if I should break up the Notebook into diversity & composition? It’s getting really long and overwhelming with all the analyses moshed together

  • Still can’t quarto render in Jupyter Lab on raven server, need to figure out how to get those interactive jupyter plots in my notebook!

15-AUG-2023

  • met with Dr. Amy VanCise about microbiome analysis:

    • Look into work by WHOI Amy Apprill, Laura Weber, Cynthia Becker

    • Focus analysis on community composition over diversity statistics

      different sampling depths across different samples … subsample the counts without replacement so that each sample has the same number of features

    • Differential abundance analysis on microbial community is similar to differential gene expression analysis!

    • Sampling depth is normalizing between samples

    • Look into getting a UV Sterilizer

    • Do the analysis without blank, mock, & env samples included… get a clean look at only treatments

    • Look into R Vegan package

    • Phred score: spatial, 30 (or 25) is good to keep

03-AUG-2023

  • Received RNA samples back from UT GSAF

  • Used PCR Inhibitor Removal Kit on five of the samples (see RNA Woes post here) :

    • 1-CA2a

    • 1-CH2a

    • 1-Ea

    • 1-PA2a

    • 1-PH1a

  • PCR Inhibitor Removal Kit said to add 50-200uL of RNA, but I only could add 30uL. I took the 5 samples from the 96-well plate and augmented them with all the leftover diluted normalized RNA.

  • Nanodrop note: blank should result in a spectrum that varies no more than 0.050A in the 1mm path. For this batch I used the Roberts Lab Nanodrop and the blank was -0.009/-0.008 10mm path.

  • Shipped DNA to Mr. DNA and RNA to UT GSAF!

06-JUN-2023

  • Normalized all 20 RNA samples

05-JUN-2023

  • Re-normalized 2-CA2a DNA and successfully got it to 19.5, 19.2 :D

  • Worked all day to normalize RNA with mixed results. In the first batch, 7 out of 20 samples were ‘off’ of the target concentration of 25ng/uL by enough to make me want to redo them (one was way high at 230ng/uL, others were too low at ~10ng/uL)

  • I first re-ran the qubit (2nd qubit run) and got really poor results, with all the rerun samples too-low, (even the one that was previously 230ng/uL!?)

  • I then re-normalized the samples and ran them on qubit again (3rd qubit run). In this run 4-PH1b hit the target, the rest were still too low

  • I re-normalized the samples for a third time (with some increasing concentration modifications) and ran them on qubit for a 4th time. In this run 4-PA2a hit the target, the rest were still too low, and 2-PH2a even got worse despite increasing concentration.

  • Ended the day unsatisfied with the following samples too low for normalization despite 4 attempts:

    • 2-PH2a - too low

    • 2-CA2a - 15.0, 15.4

    • 1-PA2a - 10.2, 10.0

    • 1-PH1a - 17.6, 17.6

    • 3-CH2a - 15.0, 14.6

    • 4-CA1a - 14.0, 13.0

02-JUN-2023

  • Normalized DNA (still have RNA left to do)
  • Tested normalized DNA on Qubit BR DNA assay, results overall were good but a smidge lower than my goal

  • read up on NanoDrop vs. Qubit

  • reached out to Sam White about Ubuntu/Windows dual-boot computer in lab 236, which is connected to the Thermo NanoDrop 2000c Sam shared:

    FYI, if you’re solely using the NanoDrop for quantification (i.e. not worried about 260/280), then I’d highly recommend just relying on the Qubit, with both DNA and RNA. The reason for this is that the NanoDrop will almost always over-“calculate” your sample concentrations (both RNA and DNA). The reason for this is that the NanoDrop is a spectrophotometer and measures light absorbance. With almost all DNA/RNA isolations, there will be residual DNA or RNA in your sample. The NanoDrop cannot distinguish between the two molecules, because they’re both made up of the same material; nucleotides. Nucleotides, regardless of their of their origin will absorb light at an average wavelength of 260nm.Since the Qubit assays use molecule-specific dyes, the dye will only bind to DNA or only to RNA. The dyes will not bind to any carryover of other types of molecules in the sample, so the accuracy (and sensitivity) is much, much higher than the NanoDrop.

      • no purchases in June!

        The University of Washington is transitioning from their old DOS-based system to Workday Finance, with a Go Live date of July 5th, 2023. During the transition period, there will be some disruptions to normal operations, and the continuity of research and teaching and minimizing the impact on faculty, staff, and students is the priority. There will be Restrictive Periods during which no one will be able to process purchase orders or obtain reimbursements in ARIBA. Exceptions may be made for urgent or emergency purchases. Travel reimbursements and non-travel-related reimbursements should be submitted before June 9th, and processing will resume on July 5th. Blanket Purchase Orders that are expected to be active past June 30th, 2023, will not be automatically transferred to Workday, and all continuing BPOs must be manually reentered by the College of the Environment. Navigating the transition will require patience and close partnerships between research and administrative groups

  • Today I setup my GitHub ‘notebook’! This is the beginning of my exploration of using GitHub to jot down thoughts, record ‘daily bits’, and organize the procedures and methods I’ll use in my thesis research

  • zbengt introduced me to ‘elicit’, a lit review search AI. I searched “What is the role of endocrine signaling in cnidarian development” and found an exciting paper titled “Sea Anemones Responding to Sex Hormones, Oxybenzone, and Benzyl Butyl Phthalate: Transcriptional Profiling and in Silico Modelling Provide Clues to Decipher Endocrine Disruption in Cnidarians” authored by Morgan et al. in 2022

  • I explored another AI, ChatGPT, and gave it the prompt “write me a poem about corals and oysters and mothers” and it returned:

    • Coral reefs, a vibrant sea of life, A home for countless creatures, rife. Oysters, clams, and mussels too, All nestled safe, their shells in view.

      But danger lurks, the waters warm, The coral bleaches, it’s colors torn. Mother Nature’s wrath, a sight to see, But we can help, if only we believe.

      For mothers, fierce and loving beasts, Will do what it takes, to protect at least. Their young and home, with all their might, They’ll fight and strive, through day and night.

      So let us join, in their noble quest, To save the reefs, and all the rest. For oysters, corals, and mothers too, Deserve a chance, to make it through.

  • I followed up with a ChatGPT prompt “what are examples of endocrine signaling in cnidarians?” and it returned:

    • Endocrine signaling is the process of communicating information from one cell to another by releasing hormones into the circulatory system or through direct contact. In cnidarians, endocrine signaling can be used for a variety of functions, including the regulation of growth, development, and behavior.

      One example of endocrine signaling in cnidarians is the release of growth hormones, which stimulate the growth and development of cells and tissues. For example, in some species of cnidarians, the release of growth hormones is regulated by the action of a hormone called insulin-like growth factor (IGF).

      Another example of endocrine signaling in cnidarians is the regulation of reproductive function. In some species of cnidarians, hormones called gonadotropins are released by the endocrine cells of the gonads (sex organs) to stimulate the production and release of gametes (sex cells).

      Endocrine signaling is also involved in the regulation of behavior in cnidarians. For example, some species of cnidarians release hormones called neuropeptides that act on the nervous system to regulate behaviors such as feeding, movement, and response to stimuli.

      Overall, endocrine signaling plays a vital role in the regulation of various functions in cnidarians, including growth, development, and behavior.

​**Is this is all true!? I’ll have to follow-up with my own dive into primary literature…

  • Another ChatGPT AI response, when asked the same questions, but prompted to provide references:

    • Examples of endocrine signaling in cnidarians include the release of hormones in response to stimuli such as touch, temperature changes, and changes in light intensity.

      For example, the hormone adenylate cyclase-activating polypeptide (ACAP) is released from cnidocytes in response to a variety of stimuli and activates adenylate cyclase, leading to the production of cyclic adenosine monophosphate (cAMP) and the regulation of various physiological processes.

      Other signaling molecules that have been identified in cnidarians include cyclic guanosine monophosphate (cGMP), inositol triphosphate (IP3), and Ca2+-dependent signaling pathways.
