The eSkeletons Project

Merlot chemistry - 1 hour 37 min ago
This interactive site allows participants to learn about skeletal anatomy by viewing the bones of a human, chimpanzee, and baboon. Users select a bone from the list of four bone types on the skeletal image, and launch the bone viewer. A detailed look at each bone from six viewing angle options is provided along with the option to select another bone or make a comparison with another species (chimpanzee or baboon). The Comparative Anatomy section enables users to make direct comparisons of bones. The material is appropriate for science teacher education as it illustrates how careful observation leads one to wonder about the dizzying beauty of a planet that works by bringing us one different creature after another.

VR Molecules

Merlot chemistry - 1 hour 37 min ago
VR Molecules presents dynamically and interactively the vibration and rotation modes for 24 molecules (out of a more extensive list) containing up to twelve atoms. It allows the user to create and save on his or her hard disk documents containing, much in the same way as Power Point presentations, up to 10 "pages", each featuring one or two molecules with specific parameters (viewpoint, active modes, etc.). These presentations can be made available through the Internet, with optional sound and text explanations associated with each page.The latest, augmented version of VR Molecules, called VR Molecules Pro 1.1, is available online as well as in a stand-alone version (Mac and Windows).To view a video of the award winning author, go to View VR Molecules - Chemistry Award Winner 2007 video VR Molécules est un logiciel de simulation (en ligne et en mode local) permettant de visualiser et d'explorer les modes de vibration et de rotation des molécules (24 molécules sont disponibles).Il peut tout aussi bien être utilisé par le professeur pour préparer des démonstrations en classe, intégrer des animations (interactives ou non) dans ses documents HTML, que par les étudiants pour revoir les démonstrations présentées en classe et explorer par eux-mêmes la vibration et la rotation des molécules.La plus récente version (1.12) de VR Molécules, est accessible en deux versions : en ligne et en mode local (à télécharger, pour Mac et Windows).

The Auscultation Assistant

Merlot chemistry - 1 hour 37 min ago
This provides text description and audio examples of various heart and breath sounds. The sounds are broken up into certain catagories. The heart sounds are divided into systolic, where you can hear aortic stenosis, mitral regurgitation, etc.., and diastolic, where you can hear mitral stenosis, aortic regurgitation, etc.. The lung sounds provide examples of cackles and wheezes.

ScienceOnline2010 - introducing the participants [A Blog Around The Clock]

Science Blogs Physcial Sciences - 6 hours 25 min ago

scienceonline2010logoMedium.jpg

As you know you can see everyone who's registered for the conference, but I highlight 4-6 participants every day as this may be an easier way for you to digest the list. You can also look at the Program so see who is doing what.

Hope Leman is a Research Information Technologist at Samaritan Health Services. She runs ScanGrants (a free, subscribable (via email or RSS) online listing of grant opportunities, prizes and scholarships in the health and life sciences and community service fields), tweets and blogs on Significant Science. At the conference, Hope will do a demo of ScanGrants.

Ernie Hood is a freelance science writer and he hosts a weekly science radio show - Radio In Vivo - at the local radio station WCOM-FM in Carrboro, NC. Ernie is currently presiding over SCONC - the organization of Science Communicators of North Carolina.

Elle Cayabyab Gitlin writes for Ars Technica, blogs and tweets. And she is always a great help to us at the conference, every year volunteering to help.

Peter Janiszewski is an Obesity Researcher (PhD Candidate) in the Exercise Physiology Lab at Queen's University, Ontario, Canada, a Science/Health Blogger at Obesity Panacea, a freelance writer, a musician, and a Twitterer.

Jayme Corbell, another veteran of our conferences, got her PhD in chemistry at Duke and now works at Catalent.

Jonathan Lifland is the Media and Communications Manager at PNAS (Proceedings of the National Academy of Sciences) and is on Twitter

Seeing Laser Beams [Built on Facts]

Science Blogs Physcial Sciences - 19 November 2009 - 9:15pm

Ok, see counselor Troi firing her phaser?

You see this kind of thing all the time on film in scifi. Whether it's Star Trek, Star Wars, or pretty much anything else, energy beams fired from future weapons are visible. Usually someone will point out that in fact laser beams are not visible in this manner. To see light, it has to reach your eyes. This is clearly not possible when all the light is actually traveling down the beam path. You can see this in action with laser pointers - only the spot where the light hits and diffusely reflects is visible. The path is not.

Writers of TV shows usually explain this by saying that the beam is not strictly light, but some stream of particles that slightly emits to the sides along its main path. While this has its own problems, at least it acknowledges the issue.

But what's even more interesting is that in fact there are already automatically particles present along the beam path in the atmosphere. Some of them are sizable particles like dust, others are individual atoms and molecules. Generally they don't scatter much light, but if the light is intense enough then the small amount they do scatter is enough to see. And so you have a visible laser beam. Here's one in my lab:

laserbeam.png

The beam scatters off the air and you can actually see it as a straight line. Apologies for the terrible camera phone picture, I really need to get a classy camera that can take nice pictures. This is not actually a laser I'm working on, so honestly I'm not sure which variant of frequency-doubled Nd:something laser this is. Probably Nd:YLF.

This is used to pump an infrared ultrashort-pulse laser with a repetition rate of 1 kHz. This can itself be focused to a point in the air, which becomes visible as a little stationary spark as the intense beam ionizes the air. This produces a 1 kHz buzz which can easily be heard by the unassisted ear.

I have to say it's a nice job perk that I can see old science fiction tropes come to life pretty much every day. :)

I Can Haz Books! [Uncertain Principles]

Science Blogs Physcial Sciences - 19 November 2009 - 8:52pm

It's not often that I regret having a cell phone that is just a phone, but this is one of those occasions-- I stopped by my publisher today to talk about marketing and publicity, and record a video for the web, and got a stack of finished copies of the book, hot off the presses. If I had a cell phone camera, I'd post a picture, but I don't, so you'll have to settle for a plain-text "Woo-hoo!"

On an only vaguely related note, our cultural activities in NYC will include some college hoops, as there's a preseason "tournament" taking place at Madison Square garden tonight. Syracuse vs. Cal, and UNC vs. Ohio State. Not a bad double bill for November basketball.
