I’m taking a break from RNA to spend time with my new baby and work on my new online cooking show Building Blocks.  On our show you learn to make your own ingredients for more fun and flavorful cooking.  I have a blog for the show here.  Please come check us out and tell your foodie friends!

We have episodes Making Coulis and Making Beef Stock up which include some of my favorite recipes, like meat pie and strawberry lemonade.  We have already shot our next episode, a lesson on Italian red sauce “Sunday gravy” with guest cook Vinny Pasceri.  Look for that late next month.  

I’ll leave this site up but disable the comments.  You can contact me at kim[at]buildingblocksshow[dot]com or go to the new  blog location and leave a comment there.

Rare Piebald Deer on Orcas Island (Washington State) September 4, 2007

I had the good furtune to see a piebald deer while visiting the Spring Bay Inn on Orcas Island in Washington state a few weeks ago.  Isn’t it pretty?

My father-in-law, a geneticist, says it is not a result of inbreeding, as one fellow inn guest had told me, but simply a genetic difference.  I am having trouble finding reliable information on this variation.  Does anyone have a scientifically sound source of information about it?

The end is near September 3, 2007

No, I have not subscribed to a new apocalyptic cult, I have applied for graduation!  Assuming I can complete six more classes in the next nine months, I will graduate in June.  It’s been a long road, so it feels great to know I won’t be an undergrad all my life. 

The reason I haven’t been blogging here lately is not for lack of things to talk about, but because I’ve had way too much going on.  I went to North Carolina for a workshop at the Statistics and Applied Math Sciences Institute, received a scholarship to participate in the Summer Institute in Statistical Genetics in Seattle and received a grant from NASA to continue my microRNA research this summer.  These were all fantastic opportunities and I need to do some reflective blogging on them before I forget everything. 

Ignite Seattle! III April 6, 2007

Last night I went to my first meeting of Ignite Seattle, which was the third meeting ever of this “night for geeks, techies, and makers.”  Much thanks to Nancy for inviting me, because I had a great time.  The highlight of the night was a group airplane making contest, which I thought was a very cleaver ice breaker as well.  Much better than the usual geek meetings where before the talks start you have to roam around the room making small talk with strangers.  Other things I liked:

The format of the talks was cool.  Five minutes from each person (enforced), so the pace was quick.  I had assumed when I saw the list of speakers that we’d have to choose and go off in groups, but was pleasantly surprised that I’d get to hear from each speaker.

The venue was very old-school Seattle/Cap Hill, which, for a native, is nice to see.  CHAC has a bar, music, lights, stage – the whole shebang.  I mistakenly brought my laptop, assuming there’d be power and wireless and opportunity to use it (it was as geek meet-up after all).  But no, it was much more casual, people interactive and we spent a good deal of the night moving around, so it was really just a hassle to keep an eye on.

What I found interesting was the balance between education and marketing.  Since most of the speakers are from some company, many of which are the owners, sometimes I wondered if their intent was more to educate the audience or compel them to use their products.  Other bloggers I know are happy to sit there and be advertised to, because they enjoy keeping up on the latest gadgets, but I’m more interested in learning the technology and techniques behind the scenes.

I’m trying to choose a favorite speaker…  Although I don’t have much interest in beekeeping, Jordan Schwartz gave a great talk on beekeeping and the hive mind.  He is such an energetic speaker, I think I’d go hear any talk he gives.  I wonder how much public speaking experience he has.  As a side note, I would have liked to hear more about his theories on colony collapse disorder, as I’ve heard a lot about it on NPR lately.  The most interesting talk content wise for me was Alex Hopmann’s talk on maximizing performance in aircraft engines.  I always enjoy learning more about how engines work and I had no idea how much you could vary the fuel economy by controlling the gas/air mixture while having minimal effect on speed. 

All in all, fabulous time was had by me.  Looking forward to Ignite IV!    

 

  

A new quarter… already??? March 26, 2007

That was the shortest spring break yet!  It was just over a week and I barely made a dent in my to-do list.  Oh well, spring quarter has begun and I have my first genetics class!  It’s called “Genome Informatics,” so it’s right in my area of interest.  That is pretty exciting.  I’m a little bummed that the only math class I have this quarter is mathematical reasoning, beacause I’m not sure how much math will really be involved.  I was really starting to enjoy linear analysis by the end of last quarter and was wishing we were on semester classes so we could get a bit more indepth with the Laplace stuff.  I’ll have to see what else I can take in that area of study another quarter. 

I have a ton of updating to do on the journal articles side that I was hoping to do over the break.  I’ll see if I can get on top of it now.  I like to feel like I’m keeping up on all the latest research, but I have to prioritize classes and my own research.  Hopefully some interesting news on my own research to share in the next week, but I’ll have to keep my mouth shut for a few more days.

Conference Helps Women take on the Physics World February 22, 2007

Posted by Sacha in Science, Women.

I just read a fantastic article by Candace Partridge over at Inkling Magazine about the University of Southern California’s Undergraduate Women in Physics Conference.  She really gets to the heart of the issue.  Here’s a little excerpt, but she is a great writer, so I encourage you to go read the full piece.  She is relaying a conversation with her mom who asks, “Yes, but why just for women? Who cares?”

I paused, a bit puzzled, “Er, because there aren’t that many of us? We’re under-represented.” She oohhhed a bit knowingly, then started her spiel.

“Well, you know, men’s and women’s brains are just different. It’s just genetics, you know. Women are naturally better at things like English. You’re just a special one,” she laughed. 

I cringed. “Mom, this is exactly the sort of crap that we’re fighting against, and it’s even worse that women themselves buy into it. Thinking like that made me get an English degree, because I thought I wasn’t good enough to do math. And you can see that’s not true at all.”

She said nothing more. But I thought about that roomful of engaging and intelligent women. I’m glad to know I’m definitely not all that special and I’m certainly not the only one. That, in essence, was what the conference was all about.

I have close friends and family that believe this.  About half of them are women.  Why do we participate in our own oppression?  Does it make us feel better about not pursuing our dreams?  Would it drive us batty to realize we aren’t living up to our true potential?  Here’s a news flash:  There is no genetic proof.  As my statistics teachers tries to drill into our heads everyday, it is almost impossible to prove that something doesn’t exist.  This difference does not exist and that is difficult to prove, but I provide here as evidence an entire conference of female undergraduate physics students at the University of Southern California.   

Programs Help Women Advance in Academia February 22, 2007

Tonight I had the honour of attending my first Association of Women in Science (AWIS) meeting.  There was a panel discussion from Women in Academia, which focused on organizations that support female growth in academia.  The panelists were Dr. Claire Horner-Devine, Dr. Eve Riskin, Dr. Joyce W. Yen, and Dr. Sheila Edwards Lange.  I’m pretty sure all of the panelists worked in some way with ADVANCE, a NSF funded program that works to create institutional transformation that allows women to be successful in their education and careers at universities around the country.  Their idea is to change the institution to support faculty success for minorities instead of focusing on changing women and other minorities to fit preset roles.  Dr. Horner-Devine is also involved in Women Evolving Biological Sciences.  This is a symposium that specifically addresses women moving from early career stages to tenure track and leadership roles. 

The entire evening was very interesting and all of the panelists had a lot to contribute on the topic.  I learned a lot about ways in which the NSF tracks the success of the ADVANCE program.  One criteria they evaluate on is space allocation, in other words, lab size.  Why do women get allocated less space?  Well, you may guess that they aren’t pushy enough and while this is true, it is also true that they don’t realize they need to ask and negotiate for it.  Aspects of your job like lab space can greatly affect retention, so even if you hire 50% women, if they get shafted on the extras, they’ll leave for somewhere else eventually and you’ll still be left with less women.

Two other facts I learned is that the University of Washington is first in federal funding dollars for public institutions and second behind Hopkins out of public and private.  We also have the most post-doctoral researchers of any institution in the nation.  Incredible.     

Overall, it was a well-spent evening and I look forward to attending meetings in the future.   If you’re a scientifically minded woman in the Seattle area, feel free to stop in on a meeting.   Click here for more information.  There is also a Women in Science Happy Hour at the Allen Institute for Brain Science on March 7, 2007 at 6pm.  For more information or to RSVP, e-mail Theresa Zwingman at:

Are microRNA required for ovarian stem cells? February 20, 2007

Posted by Sacha in Genetics, microRNA, Science.

A report was published this weekend in the journal Current Biology titled “Dcr-1 Maintains Drosophila Ovarian Stem Cells.”  The authors were Zhigang Jin, Ph.D, and Ting Xie, Ph.D, from Stowers Institute for Medical Research (Missouri) and the Department of Anatomy and Cell Biology (U of Kansas), respectively. 

According to this paper, the ovaries of Drosophila (a type of small fly) contain three types of adult stem cells: 
Germline stem cells (GSCs)
Escort stem cells (ESCs) and
Somatic stem cells (SSCs)

The authors go into much detail about GSCs and SSCs and the role of Dicer-1(Dcr-1) ribonuclease to maintain them in the Drosophila ovary.

So what is this review doing on an miRNA blog?  In the last paragraph of the article, Xie and Jin state “Because Dcr-1 is an essential component of the miRNA pathway in Drosophila, we further propose that miRNAs processed by Dcr-1 are essential for controlling self-renewal of GSCs and SSCs.”  They go on to explain the problems associated with the absence of miRNA generated by Dcr-1, such as depletion of stem cells.

An article on Biology News Net quoted Dr. Xie on the importance of the role of miRNA:

“We are in the process of identifying the microRNAs that are important for stem cell self-renewal,” said Dr. Xie. “Understanding the mechanisms controlling stem cell self-renewal will be crucial to our developing the ability to expand stem cell populations for performing tissue repair.”

Straight from the Nucleus: miR-29b January 13, 2007

Another paper on microRNA.  This one is about miR-29 was published in Science‘s Jan. 5, 2007 edition.  It’s titled “A Hexanucleotide Element Directs MicroRNA Nuclear Import.” 

This is basically a note to myself to read it later.
