BIG ANNOUNCEMENT!

This blog has been quite quiet the past few months, since between taking my comprehensive exams, two short tours, and starting thesis work I've been super busy. But there is another reason I have been quiet.

I'm beyond honored to say that this blog, Science with Moxie, has a new home on the brand-new Scientific American blogging Network.

Please check me out there, update your RSS feeds, and check out all the other fantastic people with whom I share a new home.

Touring the East Coast and #nycscitweetup

Tomorrow starts my band's second East Coast tour. As luck would have it, we're going to be playing very close to the #nycscitweetup, which is March 7th at 7 pm at Ninth Ward.

Our show is a short L-train ride away in Brooklyn, at Public Assembly. We go on at 10:30 pm, which means I will be able to hang out with science people for a bit in Manhattan, then jump over to Brooklyn to play a show, hopefully with some other sci people in attendance! It's probably the SciMuse dream if there ever was one (P.S. I heard BoraZ is gonna be there)!

So if you want to talk music or nerdery or even both with me in person, here's your chance! We're also hitting other places up and down the East Coast. Check out the tour schedule here.

You can also check out an interview with me about my band and our tour posted over at Star Beat Music.

Hope to see some of you out at both!

The power of rock n roll.

Can rock music boil an egg?

This is what is proposed by this quote, found on various internet locations of less than scientific repute:

"Bob Larson, a Christian minister and former rock musician, remembers that in the 70's teens would bring raw eggs to a rock concert and put them on the front of the stage. The eggs would be hard boiled by the music before the end of the concert and could be eaten. Dr. Earl W. Flosdorf and Dr. Leslie A. Chambers showed that proteins in a liquid medium were coagulated when subjected to piercing high-pitched sounds."

There is also this clip taken from the 1989 documentary Hells Bells: The Dangers of Rock N' Roll by Reel to Real Ministries:

Pour some egg whites on me.

So...is there any truth to this?

 Let's do what any good investigator would do: go straight to the source. I looked up the research paper mentioned in the quote above by Dr. Earl W. Flosdorf and Dr. Leslie A. Chambers. It's titled "The Denaturation of Proteins by Sound Waves of Audible Frequencies." And it's from...1936. Hardly the pinnacle of cutting edge research, even back in the 70s.

In the paper, sound at the frequency of 1200 Hz and wattage of 175 (click here to hear what that frequency sounds like) was found to be effective in denaturing egg whites, via the power of cavitation. Cavitation refers to the use of sound waves to vibrate the gas bubbles in a liquid. It's the same thing that happens during sonication, and you can even use it to clean things.

Bearings being cleaned in a sonicator.

So this process of cavitation was able to denature the egg proteins in a similar way that heat does and "cook" the egg whites in the paper. But this was in a highly controlled laboratory setting that used pure egg whites and special equipment to produce high frequency and energy waves of sound. Could sound waves from rock music cook an egg in real life?

I wasn't able to find any scientific research articles on this claim, but The Straight Dope did their own experiment that resulted in a no. My friend Katie Herzog's brother also performed an earlier experiment in 1990 for a science fair.  Katie was gracious enough to allow me to present a few pieces of exclusive family pictorial evidence.

Given these two independent experiments, I think it is safe to say that while egg whites can be cooked by high wattage, high frequency sound in a lab setting, it is highly unlikely that rock and roll music will produce a completely cooked hard boiled egg in the middle of a concert.

ScienceOnline2011!

This post is so long overdue, but I really wanted to blog about my second year attending the ScienceOnline (un)conference held in Research Triangle Park, NC. Even though I attended the conference last year as well, this year managed to top even my glowing review of 2010's event.

The main difference between this year and last year for me was that I was able to participate in some of the pre-conference festivities this time around. Thursday night was a presentation by the organizers of the conference, Bora and Anton, using the awesome Prezi software. I always feel like ScienceOnline is one of the most high tech and fun conferences, and discovering Prezi as an alternative to Powerpoint slides was a great example of this. I want to use Prezi when I give my thesis defense to show up everybody else! You can check out the presentation here, which included the embedded video featured at the end of my interview with David Kroll. The Prezi presentation was followed by the keynote speaker, Robert Krulwich of Radiolab fame. It was so incredibly strange to hear what is usually a disembodied radio voice coming from an actual...well, body. I was in nerdgirl heaven because I. LOVE. RADIOLAB. After Krulwich's speech I got on stage with David Kroll and did a live performance of "Minister of the Ether" at the open mike. It was so much fun to play bass on a song with someone I'd just interviewed for SwM, and who has been so helpful and kind to everyone around him. David Kroll actually got a community service award Thursday night too.

Of course, at such a tech-savvy conference, this moment was immortalized on Twitter.

Friday morning brought lab tours and a beer and book reception. The lab tour I chose was a guided tour of the Record exhibit in the Nasher Museum, but I'm just going to gloss over that in favor of gushing about the book and beer reception. Get this: you walk into the door. You are handed a square package wrapped in brown paper. You open it. It's a book. Free. For you. You are overcome with joy. You walk to the bar to get a beer. You order. You try to pay. The bartender tells you, no, it is free. Authors are getting up on stage and reading from their books. You wonder what you did to deserve such merriment. And then, you are mingling, holding your free book and your free beer, and you run into your nerdgirl idol, the keynote speaker from last night, Mr. Robert Krulwich. And you have a five minute conversation with him. And then you go home and die happy. That was totally what happened, minus the dying part. But I was still super happy and even more impressed with the planning of it all.

Saturday and Sunday were the days of the actual conference. I really liked the format of the pre-conference events because by the time the actual conference rolled around I had already met lots of interesting people and felt a little more connected with everybody there. I attended panels on mostly on blogging to a general audience and blog networks. I met people whose writing I'd admired but had previously only known on the internet. Bonds were forged and learning was aquired. There is already tons of great blog coverage of the conference, so I won't get into specifics here, but suffice it to say I learned and gained a lot from interacting with all the people around me. I learned things about how to communicate science more effectively in my posts, and I felt a sense of unity that inspired me to get more involved in connecting with others in the science blogosphere. Getting some invaluable face time with others who believe in the same causes that I do was endlessly rewarding.


At the end of the conference I had met some amazing people, gained several new twitter followers and blogs to read, and had many new ideas to think about and incorporate.

Joseph Hewitt's amazing rendering of yours truly.

Oh, and I gained a comic book with my likeness drawn onto it.

I'll definitely be back next year!

SciMuse: Dr. David Kroll: scientist, musician, mensch

(this post is crossposted at the Science in the Triangle Blog)

Dr. David Kroll is a man who wears many hats: researcher, professor, science blogger, and musician. His life seems to tie together all these separate parts into one cohesive theme of giving back to the community and enriching the lives of others.
Kroll grew up on a neighborhood perched on a hill that afforded a direct view of the Roche tower in Nutley, New Jersey. Growing up looking at the Roche tower every day lead him to take an interest in pharmacology and the drug industry. He went to college as a first generation student and majored in Toxicology at Philadelphia College of Pharmacy and Science, following his dream of someday being able to help others by working in that same tower.
Throughout his career, Kroll kept in mind that knowledge can be used inclusively or exclusively. He wanted to use his knowledge of pharmacology to help regular people navigate the drugs that they were taking, but wasn’t very prepared for the discovery that science could be a profession so isolated from the public at large. He starting blogging as an outlet for his desire to educate the wider public on drugs, supplements, and pharmacology in general. Kroll recently celebrated his fifth year of blogging in December 2010, blogging for ScienceBlogs, the American Chemical Society’s CENtral Science, and for PLoS Blogs over the years.

The path of Kroll’s educational and musical career intersect at many points in his life. He started playing guitar at the age of fourteen as a way to escape being labeled as a “real dork in high school.” However, the release of The Police’s Outlandos D’Amour and Joe Jackson’s Look Sharp lead him to an appreciation of the bass, which he switched to a year after picking up the guitar. This step proved to be successful as he went on to play bass in his first band with his high school girlfriend, his high school friend, his guidance counselor, and his high school history teacher. Kroll cites his history teacher as being a huge influence on getting him interested in the history of social injustice and specifically the history of science. His first band played bars and clubs around town throughout Kroll’s high school years.

In college, he played mostly solo but would occasionally play with his old high school band while visiting home. Around the time he was finishing college, Tom Petty and the Heartbreaker’s “Southern Accents” was released and proved to be yet another pivotal album in his life. This Tom Petty album release was right around the time of his acceptance into a pharmacology doctorate program at the University of Florida in Gainesville, the hometown of the Heartbreakers. Tom Rowe, his advisor at UF, was supportive of a work/life balance, and this freedom allowed him to play in a U2 tribute band for two years in graduate school.

After finishing his Ph.D., he landed an offer for a postdoc position at Roche, the original setting of his dream of working in pharmacology. He was literally within days of accepting when he got offered a position at the University of Colorado in Denver. He ended up taking the position in Denver instead, where he worked on the transcriptional regulation of the CREB protein and a shortly afterward went on to land an Assistant Professor position in the School of Pharmacology at the University of Colorado Health Sciences Center.

The move to Denver proved to be fortuitous to his musical life as well. One day he was typing up an abstract in the main office of the Division of Endocrinology, Metabolism, and Diabetes at the Univ of Colorado Health Sciences Center when a endocrinology fellow walked in to answer a page for a gig he was playing later that evening. Kroll struck up a conversation, mentioning that he was a bass player, and got invited to jam with Dan Bessesen, and his bandmate, Jay Reusch, a cardiologist whose wife was also an endocrinology fellow. These jam sessions evolved into Dogs in the Yard, an adult alternative band that lasted for eleven years, from 1990 – 2001. They played gigs at the medical center, fundraisers, and even the endocrine department Christmas party. They released two CDs, one in 1997 entitled “Sunday Afternoon” and one in 2001, “Til the Summer Fades Away.” About eight years into the band, EMI called and offered them a move to LA to pursue the possibility of a record deal. But as all of the people in the band had work and family obligations, they decided to turn it down.


Eleven years is an ancient time in band years, but all good things must come to an end. Kroll left Dogs in the Yard after he met his now-wife at a cancer research conference in Colorado. She was a Duke oncology physician-scientist who lead him to doing a sabbatical at Duke that eventually lead to a job offer in the North Carolina Research Triangle at RTI International. Despite the loss of the band, he continued his musical career with other scientists, playing with Nick Oberlies, a chemistry postdoc, scientific collaborator at RTI, and DJ at Duke University station WXDU. He also played with Cole Guerra, a psychology graduate student at Duke who Kroll contacted after reading an article featuring him in the local Triangle Independent Weekly. Kroll joined his band on bass for shows at Cafe Driade and Local 506 in Chapel Hill. However, at RTI he missed the joy of teaching students and moved to take a professorship at North Carolina Central University in Durham.


Kroll has continued to keep in touch with music at NCCU, playing the annual Faculty Talent Show and working on solo projects. Lately, he’s been writing songs under his own name in preparation to record a solo album called “From Denver to Durham.” The namesake of his album comes from the fact that both cities have an interstate exit numbered 284 that leads to the international airport, a testament to the myriad levels of interconnectivity in both his scientific and musical career.

At the BlogTogether bash in Durham in October, he debuted a song called “Minister of the Ether” that pays tribute to Anton Zuiker in celebration of his 10th year of blogging and to all his work in the blogging community. Check out an exclusive video below of Kroll giving an acoustic performance of the song under the bull statue in Durham’s city center.
