Liveblogging from the Hi-Tec conference
I'm currently at the Hi-Tec conference in Scottsdale, Arizona. (If you follow me on Twitter - www.twitter.com/@digitalbio - you may have seen me complaining about the temperature). It's an interesting conference, so I'm going to share some of the things that I'm learning.
Dr. Travis Benanti and Dr. Steve Fonash from Penn State University are presenting an interesting session this morning on nanotechnology.
Luckily, you don't have to know anything about nanotechnology to find the session fascinating.
If you're interested in learning about nanotechnology…
This is a video that a friend made that shows, very clearly, how to pour an agarose gel, load the samples and run it. I especially like the way he used a bit of time lapse photography to show the dyes separating as the gel ran.
"Yo, you regulate it's genes"
The English makes me cringe, but I love the idea. Tom McFadden, an associate instructor at Stanford, has made a series of Biology rap videos and posted them on YouTube.
Yo, check it out.
If you haven't seen these, check out Jake Young's collection of videos showing T cells getting infected by HIV. The best one is at the bottom of the post.
Have you ever wondered how to find things in the NCBI databases? Maybe you tried to find something but didn't know how it was spelled. Or maybe you tried to use a common name like "pig" or "deer" to find information in a database, not knowing that all the organism names are in Latin. Or perhaps you're wondering just what kind of information is stored for different kinds of records and if you could search for this information.
I wrote a book that covered this topic quite thoroughly, a couple of years ago, for the NCBI structure database. Now, I've decided to make some movies, too.

Teachertube looks and works much like YouTube, but you're much less likely to run across videos that Not Safe For the Classroom.
All of these videos are made by students and teachers. According to the Dallas News, there are 54,000 videos on the site already and 800,00 visitors every day.
I especially enjoyed watching Abbot and Costello doing math problems.
I made this video last night with a Flip Cam Mino. There are some kind of wild trippy effects. Sometimes it even looks like there's popcorn shooting out the top of the space needle. It was sure fun!
Happy New Year everyone!

Before mammals, before dinosaurs, before bacteria, or plants, there was something else; a protocell containing RNA.
The Exploring Origins Project has excellent animations of protocells, a timeline of life's evolution, and best of all- fantastic animations of the RNA world.
You can see how RNA folds, ribozymes (RNA that catalyzes chemical reactions), and learn about the role of RNA when the Earth was young.
BTW- I made this ribozyme image with Cn3D. The RNA is synthetic - made by humans with machines, that is, and this molecule can cut chemical bonds.
This video from WDSU shows Mr. Green Genes, the transgenic kitty, in the dark and in the light.
There's also an interview with Dr. Betsy Dresser, who very briefly talks about the work at the Audubon Center for Research on Endangered Species.
Other than clips of the cat, and Dr. Dresser, the video mostly shows people taking frozen samples out of liquid nitrogen, but there's an interesting bit towards the end where they show a pipette transferring material into the nucleus of an egg cell. Mr. Green Genes is certainly a cute cat.
You can see more pictures from the Times Picayune: here and…
What happens when a group of streptococci stick to cells in your throat and start to make toxins?
Your body fights back by making clones.
The animated video, Fighting Infection by Clonal Selection, from Etsuko Uno and Drew Berry is so good that if I didn't know better, I would almost think it's really capturing clonal selection on film.
What is clonal selection?
We call this process "clonal selection" because only some lucky cells get selected for cloning. These cells have proteins on their surface that are able bind to bits of stuff from bacteria or viruses. We call that stuff "antigens…
Sometimes words fail me. Luckily, we have videos.
Many of you have probably read about Roger Tsien receiving the Nobel Prize this work for his work with the green fluorescent protein (GFP), but I bet some of you are wondering, why a jellyfish protein is worth a Noble Prize.
I think one of the best places to see why GFP is important, and also to see what some scientists do during the day, is JOVE, the Journal of Visualized Experiments.
The wonderful video, that's shown in this image, describes a new method for investigating Parkinson's disease. This is the kind of biological work that we…
Okay, watching some of the other movies makes me realize that I've been very negligent in not uploading ours.
Without further ado, here it is.
Can you guess the age of the person who made the movie? I'll give you a hint. It wasn't me.
David Ng from The World's Fair has made this wonderful video on public speaking. Or shall we say the funnier side of public speaking? I really enjoyed it!
I'd say Dave's video ranks right up there with one of my other favories, the classic: "Chicken chicken chicken"
The Periodic Table of Videos from the University of Nottingham has 118 short YouTube clips about the elements. Wired Campus recommended the Sodium clip (below). I liked it, too. It's not quite as funny as Mentos in Diet Coke, and but it's still cute and the narrator has a haircut like Gene Wilder in Young Frankenstein.

Pfizer has pledged to donate up to $10,000 to the cause of science education, through Donorschoose.org, but only if enough of you, dear readers go to Big Think: Think Science Now and vote for your favorite video.
If you're not familiar with Pfizer, they're a pretty well-known drug company. You probably read about one of their products every time you delete messages from your e-mail in-box.
You don't even have to watch the videos, just vote.
I strongly recommend watching the videos, though. They are all profiles of scientists who work at Pfizer or other research organizations. It's…
Students, teachers and scientists converge tommorrow morning from all around the Puget Sound region and elsewhere in Washington to share their experiences and talk about science. The students will present posters, science-themed music, art, drama, and many different types of projects that involved first-hand research and investigation. Scientists from the local biotech companies and research institutions talk with the students and judge the projects.
The public viewing time is tomorrow, May 28th, between 9 am-12 noon at the Meydenbauer Center. More information can be found here.

Over 2600 genetic diseases have been found where a change in a single gene is linked to the disease. One of the questions we might ask is how those mutations change the shape and possibly the function of a protein?
If the structures of the mutant and wild type (normal) proteins have been solved, NCBI has a program called VAST that can be used to align those structures. I have an example here where you can see how a single amino acid change makes influenza resistant to Tamiflu®.
This 4 minute movie below shows how we can obtain those aligned structures from VAST and view them with Cn3D.…
In the class that I'm teaching, we found that several PCR products, amplified from the 16S ribosomal RNA genes from bacterial isolates, contain a mixed base in one or more positions.
We picked samples where the mixed bases were located in high quality regions of the sequence (Q >40), and determined that the mixed bases mostly likely come from different ribosomal RNA genes. Many species of bacteria have multiple copies of 16S ribosomal RNA genes and the copies can differ from each other within a single genome and between genomes.
Now, in one of our last projects we are determining where…
Ribosomes 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,…
