Everyone loves pandas, right? In fact, these lovable bears are the most recognizable icons worldwide for endangered species, even while remaining endangered themselves. But recently, China has made an effort to protect the giant pandas' native habitat and to establish several in situ captive breeding programs to bolster the dwindling numbers of wild giant pandas, as revealed in a charming new video, Ultimate Pandas, by nature photographer, Gerry Ellis…
zooillogix | June 4, 2008A fascinating article in Livescience reveals the answer to a century-old zoological mystery: what do y-larvae grow up to become? Discovered in 1899, y-larvae are clearly young crustaceans but their adult stage could not be determined. While this in itself was perplexing, the newly discovered answer is even more startling: y-larvae metamorphosize into "simple, pulsing, slug-like masses of cells... far simpler than their larval stage." In a sense, the creatures revert backwards to forms more commonly seen further down the evolutionary ladder as they mature.
Watch the process

esiegel | April 17, 2008What is the future of this website? I'm going to be creating videos for the web about the Universe. I'll be answering questions ranging from what the Universe is like today to how it got to be that way. I'm going to address every step that we know of, from the Big Bang up to the present day.
And I'm going to do it naturally, by telling the story as the Universe tells it directly to us. I call this project Genesis. Check out the teaser trailer below, and tell your friends, because this is coming in January.
sporte | April 16, 2008Ribosomes are molecular machines that build new proteins. This process of synthesizing a protein is also known as translation.
Many antibiotics prevent translation by binding to ribosomal RNA. In the class that I'm teaching, we're going to be looking at ribosome structures to see if the polymorphisms that we find in the sequences of 16S ribosomal RNA are related antibiotic resistance.
This is related to our metagenomics project where we investigate the polymorphisms we find in 16S ribosomal RNAs.
This 6 minute video introduces ribosomes, discusses where they're found, what they're made of,…
esiegel | March 28, 2008I remember being a kid and taking karate lessons. How cool was it to go somewhere for the purpose of learning how to kick ass? It was fun, of course, and one of the things you learned how to do was to attack (strike, kick, and punch) with your entire body, not just with your limbs.
Maybe the coolest parlor trick we learned was how to break a wooden board with our bare hands. (I remember surprising the hell out of Leon Hodge years later in High School by doing it in a history class one day; Hi Leon!) We also heard the story that the way this worked was that you compressed air molecules so much…
omnibrain | March 28, 2008Someone emailed me this week asking for the location of this video so I figured I'd post this from my old blog Omni Brain.
From Sandra:
I Am the Very Model of a Psychopharmacologist is set to Gilbert and Sullivan's classic song with animation.

omnibrain | March 27, 2008 Growing up it seemed like the only science on television was Mr. Wizard, Nova, and Star Trek (ok ok ... it's fiction but most scientists love star trek). Now there are a number of channels that regularly feature science shows. National Geographic, the Discovery Channel, the Science Channel, Discovery Health, the Learning Channel, and even the History Channel. There are probably even a few more I don't even know about. It's great!
However, It seems like 90% of these 'science' shows are actually engineering shows or something else sciency but not quite science. Usually they build stuff and…
sporte | March 19, 2008Have you ever wondered how to view and annotate molecular structures? At least digital versions?
It's surprisingly easy and lots of fun.
Here's a movie I made that demonstrates how you can use Cn3D, a free structure-viewing program from the NCBI. Luckily, Cn3D behaves almost the same way on both Windows and Mac OS X.

omnibrain | March 14, 2008Here's a pretty cool African Grey doing crazy sound effects.
Another video after the fold.
Here's one of the most pointless - poorly drawn - boring you tube videos I've ever seen! I love it!
It's a girl drawing a neuron and all its parts :)
esiegel | March 11, 2008So I gave a public lecture last (Monday) night called, "Afraid of the Dark: How We Know What We Can't See" and videotaped it. Now, I'm pretty good at what I'm doing right now (research in theoretical cosmology), but I'm really good at public speaking and teaching, and here is me telling a public audience all about dark matter, how we know it exists, what makes it different from normal matter, and what I'm trying to do to find it/discover its nature for a good 40 minutes. (The intro and question/answers are cut out).
It was a lot of fun; the audience was wonderful, and actually kept me for…
esiegel | March 7, 2008Sometimes I wonder if I'm going to need to learn video editing to make this outreach thing work. I might do well to follow the lead of this guy, who's a Norwegian named Lasse Gjertsen, and who's posted a video of him "playing drums and piano."
Well, playing drums and piano kinda. But damn, I would love to have those editing skills...

I swear I'm not being paid... but it does follow the theme of our blog.
Check out their merchandise as well :)
Ok.. who is going to buy me one of these shirts?
HT: Sandra!
omnibrain | March 5, 2008Ok... for reals... this is what Therapists actually do.
Recognize the young Gregory House? It's always a little weird hearing a British accent coming out of his mouth.

esiegel | February 29, 2008The Milky Way galaxy is a relatively big spiral galaxy. So is Andromeda. There are about 20 dwarf galaxies that are gravitationally bound to us; combined with us, all of this makes up the local group. But Andromeda is moving towards us, and eventually, it's going to merge with us. I'll once again show you a video of what this merger might look like:
But what would we see, here in the Milky Way, as Andromeda got closer and closer to us? Right now, Andromeda looks like this:
But Andromeda is also very far away: about 2.3 million light years (770 kpc). The center of it is tiny on the sky, but…
sporte | February 26, 2008Do different kinds of biomes (forest vs. creek) support different kinds of bacteria?
Or do we find the same amounts of each genus wherever we look?
Those are the questions that we'll answer in this last video. We're going to use pivot tables and count all the genera that live in each biome. Then, we'll make pie graphs so that we can have a visual picture of which bacteria live in each environment.
The parts of this series are:
I. Downloading the data from iFinch and preparing it for analysis. (this is the video below) (We split the data from one column into three).
II. Cleaning up the data…
sporte | February 26, 2008This is third video in our series on analyzing the DNA sequences that came from bacteria on the JHU campus.
In this video, we use a pivot table to count all the different types of bacteria that students found in 2004 and we make a pie graph to visualize the different numbers of each genus.
The parts of this series are:
I. Downloading the data from iFinch and preparing it for analysis. (this is the video below) (We split the data from one column into three).
II. Cleaning up the data
III. Counting all the bacteria
IV. Counting the bacteria by biome
Part III. Pivot tables from Sandra Porter on…
sporte | February 26, 2008What do you do after you've used DNA sequencing to identify the bacteria, viruses, or other organisms in the environment?
What's the next step?
This four part video series covers those next steps. In this part, we learn that a surprisingly large portion of bioinformatics, or any type of informatics is concerned with fixing data entry errors and spelling mistakes.
The parts of this series are:
I. Downloading the data from iFinch and preparing it for analysis. (this is the video below) (We split the data from one column into three).
II. Cleaning up the data

sporte | February 26, 2008For the past few years, I've been collaborating with a friend, Dr. Rebecca Pearlman, who teaches introductory biology at the Johns Hopkins University. Her students isolate bacteria from different environments on campus, use PCR to amplify the 16S ribosomal RNA genes, send the samples to the JHU core lab for sequencing, and use blastn to identify what they found.
Every year, I collect the data from her students' experiments. Then, in the bioinformatics classes I teach, we work with the chromatograms and other data to see what we can find.
This is the first part of a four part video series…
