A Lab Murder Mystery

Posted by on February 18th, 2011

“A researcher is found dead hunched over her lab bench, and seven suspects are in custody. Now it’s up to 30 high school students to determine who killed her.” To quote from the UBC Science newsletter.

Don’t be alarmed, this isn’t tabloid fodder.

It’s actually part of a high school out-reach program, organized by UBC’s grad student society in chilly Vancouver, Canada. Hosting grad students were inspired by CSI, the shows, to stir up interest in research for visiting high schoolers.

Oh CSI. It’s like trash tv for bench scientists and their students (Okay..maybe not that trashy). But it’s simply irresistible even though you know it’s bad. (PCR’s that take 60 seconds to do, I mean, c’mon. But it looks so sexy…).

Now it’s also a brilliant method of interacting with students and communicating science.

Caylib Durand and Santiago Ramón-García (2010). The Use of Popular Fiction to Present a Professional Scientific Career to High School Students JOURNAL OF MICROBIOLOGY & BIOLOGY EDUCATION, 166-167 :10.1128/jmbe.v11i2.19 (Should the DOI link not work, try this one)

On the side, CSI or criminology is an actual career option for analytical chemists and molecular biologists. I remember seeing forensic education programs actively trying to recruit fresh biology grads. (e.g. BCIT in Vancouver). But you don’t need to have a forensics degree necessarily, some grads went directly into the field after grad school (something I’d heard of through their proud supervisors). It’s easy to google the recruiting websites of local law enforcement agencies. Forensic researchers usually fall under civilian work programs. Interestingly enough, salaries usually double the second year on the job. I wonder if it’s indicative of some nefarious trend. Most people can’t stomach hanging around another year? or is it just because of a lack of experienced workers in the field? If it’s anything like the actual show, I would guess it’s because it’s a lot to handle psychologically.

At any rate, ending off the post with a music video put together by disgruntled climatologists at Australia’s Commonwealth Scientific and Industrial Research Organization (CSIRO), from 2009. Who needs Al Gore to be the spokesperson for Climate Change?



Self-expression is not just for the artist (and emo teenagers).

If Animals Could Speak

Posted by on February 17th, 2011

I’ve no doubt that this is what they’d say:



Or maybe this is what they really sound like and Sir David Attenborough refused to share this with us on the BBC.

Just for fun! I bet UK residents are very familiar with BBC One’s Walk on the Wild Side. Now to enlighten the rest of the world..

Double bill: Bringin’ Stickleback / Bad Project

Posted by on January 24th, 2011

Is this Monday not quite giving you the results you were hoping for? Cheer up with a few science music videos.

This one, “Bad Project”, is being emailed around rapidly among scientists worldwide, so there’s a good chance you’ve already seen it. If not, it’s worth a watch for the costumes (made of lab supplies!) and dance moves alone.



The next video is a bit older, but a lot more positive about research, and an ode to a famous evo devo model organism.



Both videos were products of departmental science variety shows or contests. “Bad Project” was a submission for a Molecular and Human Genetics Retreat 2011 at Baylor College of Medicine, and “Bringin’ Stickleback” was a submission for the 2009 “MCB Follies” at the Department of Molecular and Cell Biology at UC Berkeley).

Have any of you ever made a video (music or otherwise) with or in your labs? Would you like to? (Asking for a reason, so please do share your thoughts. I’m looking at you, students and postdocs. You there, with your eye on the lab timer, reading the Node while waiting for your experiments… Have you ever filmed something in your lab?)

HHMI Biointeractive

Posted by on December 30th, 2010

Each year in early December, the Howard Hughes Medical Institute hosts a series of educational seminars, called the Holiday Lectures, in which researchers explain the very basic concepts of their work. The lectures make a great introduction to a topic, and all past lectures are available on the HHMI Biointeractive site or as DVDs for teachers to use in the classroom. This year’s Holiday Lecture was on viral outbreaks, but a few past lectures have been on topics more closely related to developmental biology.

The Biointeractive site also features short videos and animations related to each year’s lectures, and the 2006 Holiday Lecture series on “Potent Biology: Stem Cells, Cloning, and Regeneration” offers many interesting clips for use in teaching developmental biology or stem cell science. For example, there’s an 11 minute mini documentary in which Alejandro Sanchez Alvarado explains planarian regeneration.



On the animation section of the Biointeractive site you can find, among other things, a short explanation about creating embryonic stem cell lines, also from the 2006 Holiday Lectures.



Have a look the lists of videos and animations on the site. There are too many to all watch, but it’s worth looking around just to see what’s there, especially if you’re teaching introductory courses. There’s even an interactive transgenic fly lab on the site, and a museum!

My Hox genes were messed up

Posted by on December 13th, 2010

In Spring 2010, the Biol 460 Developmental Biology class at Pepperdine University in Malibu, Calfornia, made this video about Hox genes:



Set to the tune of Ke$ha’s “Tik Tok”, but with far more intelligent lyrics and a funnier video, the song refers to the Ultrabithorax mutation that causes Drosophila to grow a second pair of wings. Janel Gonzalez, a student in the course, wrote the lyrics and sings the part of a fly who wakes up one day to find her Hox genes are “messed up”. The affected fly compares her fate to that of other mutant flies (“I look over at my friend with antenna for eyes”) and concludes that her situation isn’t so bad (“I still can feed; and I still can fly.”)

Donna Nofziger-Plank, who teaches the course, encourages the use of art to teach developmental biology. Aside from this video, the class also held Developmental Biology poetry jam sessions, created cartoons, and used stop-motion animation. The next Biol460 course at Pepperdine runs in early 2012, and we’re looking forward to seeing what the students will come up with that year.

Echinoderm development on film

Posted by on December 6th, 2010

“I also here salute the echinoderms as a noble group especially designed to puzzle the zoologist.”

Libbie Hyman, 1955



Echinoderms are fascinating creatures. They have extensive regenerative capabilities, a mutable connective tissue that dynamically (and deliberately) changes its stiffness, and a complex system of hydraulic canals involved in the circulation of internal fluids and locomotion.

However, the most notable feature of echinoderms is the pentamerous symmetry of their bodies, derived from a bilateral ancestor. These exclusively marine deuterostomes are mostly bottom dwellers with a biphasic life cycle, where the adult tissues develop inside a bilateral planktonic larva (swimming in the water column) and metamorphose into a benthic juvenile.

Pluteus larva

A planktonic pluteus larva of a sea biscuit.

During my master’s project at University of São Paulo, Brazil, I studied the development of a different kind of sea urchin, a sea biscuit. Sand dollars and sea biscuits belong to a lineage of urchins that developed a secondary bilateral symmetry. Also, during their evolution, around 55 million years ago, the adult morphology changed in association with the occupation of sand beds; more specifically, the body flattened, the spines got shorter, the number of tube feet increased, and their feeding apparatus (lantern of Aristotle), which was absent in other adult irregular urchins, was retained into adulthood.

Since I was interested in the developmental origins of such changes in morphology I documented the embryonic, larval, and juvenile development of a sea biscuit species, Clypeaster subdepressus. After gathering all data, I compiled it into a science outreach video showing a resumé of the life cycle of this species, from fertilization to the first steps of the juveniles. Hope you enjoy it:



We collected adults from sand beds of São Sebastião Channel (São Sebastião, SP, Brazil) and induced gamete release (eggs and sperm). We did the fertilization in vitro and followed the embryonic development in the laboratory, under light microscopy. Embryos become swimming larvae, approximately 0.2 mm wide, which we fed with microalgae until metamorphosis. A diminute sea biscuit grows inside the larva. When the minuscule podia and spines are formed the larva sinks and undergoes metamorphosis. The juvenile sea biscuit reabsorbs the larval tissue and begins to explore its new habitat, between sand grains. [Numbers on the upper right corner show how much the scene was accelerated.]

The video is available to download here, feel free to reuse it and share it around! If you want further details on sea biscuit development (including images and video footage) the official description was published earlier this year.

Cell death – the video

Posted by on November 12th, 2010

Cold Spring Harbor has just published a new book on cell death by Doug Green, a larger-than-life character who will be familiar to anyone who’s ever been to an apoptosis conference. In this video, Doug talks about the apoptosis machinery and explains why cell death is critical during development.
