Adobe Illustrator Calendar from Warped Perspective
Some cells are visible to the unaided eye The smallest objects that the unaided human eye can see are about 0.1 mm long. That means that under the right conditions, you might be able to see an ameoba proteus, a human egg, and a paramecium without using magnification. A magnifying glass can help you to see them more clearly, but they will still look tiny.

Art That Illustrates the Danger of Antibacterial Everything
What you're looking at is the art of bacterial adaptation. It's beautiful. It should also make you a little uncomfortable, and a little hopeful. Part of a collaboration between Professor Eshel Ben-Jacob, of Tel-Aviv University , and Professor Herbert Levine of UCSDs National Science Foundation Frontier Center for Theoretical Biological Physics , these pictures are a visual representation of the way bacteria evolve to overcome life-threatening obstacles---like, say, hand gel.
Traveling Through Time and Stars
When the light captured in this image left the Pleiades, Nicolaus Copernicus had just published his 1543 treatise claiming that the Sun, not the Earth, was the center of the solar system. One of the nearest star clusters to Earth, the Seven Sisters are relatively young—only 115 million years old—and are in fact comprised of about a thousand stars, though only seven are visible to the naked eye. Light may epitomize swiftness, but even photons take millions of years to traverse the gulf of deep space. When our observatories finally pick up the light of distant galaxies, the galaxies themselves have long ago passed the stage recorded in their transmission to Earth. Because of this, the most distant, ancient galaxies seem to us to be still in their youth, while relatively local stars like the Pleiades, about 450 years away as the photon travels, give us more current information. In a cosmos 156 billion light-years wide, 450-year-old news is quite current indeed.Michael Mann and Gavin Schmidt The issues involved in science communication are complex and often seem intractable. We’ve seen many different approaches, but guessing which will work (An Inconvenient Truth, Field Notes from a Catastrophe) and which won’t (The Eleventh Hour) is a tricky call. Mostly this is because we aren’t the target audience and so tend to rate popularizations by different criteria than lay people. Often, we just don’t ‘get it’. Into this void has stepped Randy Olsen with his new book “Don’t be such a scientist” .
Communicating Science: Not Just Talking the Talk
The Preservation of Favoured Traces
We often think of scientific ideas, such as Darwin's theory of evolution, as fixed notions that are accepted as finished. In fact, Darwin's On the Origin of Species evolved over the course of several editions he wrote, edited, and updated during his lifetime. The first English edition was approximately 150,000 words and the sixth is a much larger 190,000 words. In the changes are refinements and shifts in ideas — whether increasing the weight of a statement, adding details, or even a change in the idea itself.
(Tele)Present at the Future

It was expired. There was no way out. I would miss four days at one of the world’s premier science communication gatherings.Higgs Boson - To download the full Higgs Boson animation for your classroom, outreach project or personal use, just visit this page: http://vimeo.com/41038445 and look for the download link in the lower left of the page.

Type 1 diabetes linked to immune response to wheat
Thursday, August 20, 2009 Scientists at the Ottawa Hospital Research Institute and the University of Ottawa have discovered what may be an important clue to the cause of type 1 diabetes. Dr. Fraser Scott and his team tested 42 people with type 1 diabetes and found that nearly half had an abnormal immune response to wheat proteins.
Some of the most impressive images in science are produced when researchers take numerical data and represent it visually through modeling and computer graphics. The Department of Energy honored 10 of this year’s best scientific visualizations with its annual SciDAC Vis Night awards, at the Scientific Discovery through Advanced Computing conference (SciDAC) in June. Researchers submitted visualizations to the contest, and program participants voted on the best of the best. From earthquakes to jet flames, this gallery of videos and images show how beautiful (and descriptive) visual data can be.
