Douglas Adams was the best-selling British author and satirist who created The Hitchhiker's Guide to the Galaxy [DVD]. In this talk at UCSB recorded shortly before his tragic and untimely death, Adams shares hilarious accounts of some of the apparently absurd lifestyles of the world's creatures, and gleans from them extraordinary perceptions about the future of humanity.
oracknows | April 23, 2010If there's one thing that has irritated me (one might even say, irritated me enough to start this blog), it's ideology or religion trumping science. Perhaps the most annoying form of this disease is the tendency of the right wing whackosphere to do everything and anything it can to distort and twist science to agree with its ideology, in particular its religion. One area that I used to write about a lot but don't so much anymore (we bloggers have to subspecialize, I guess, and these days my subspecialty is science-based medicine with only the occasional forays against forms of unreason other…
bioephemera | April 23, 2010The Anachronism (Full Film) from Anachronism Pictures on Vimeo.
The full length version of The Anachronism, a short film by Matthew Gordon Long, has been released online. The only thing wrong with it is that it isn't longer. Give yourself a treat this weekend, enjoy the steampunk, and, if you're like me, reminisce about taking a textbook out into the forest to name things in Latin! I'll just give you one warning: this is a filmmaker who, unlike many others, knows how to let a mystery rest undisturbed. Yes, the film leaves you curious as heck, but in the end, I think that's a much better…

Some 80 to 90 percent of undersea creatures make light -- and we know very little about how or why. Bioluminescence expert Edith Widder explores this glowing, sparkling, luminous world, sharing glorious images and insight into the unseen depths (and brights) of the ocean.

oracknows | April 20, 2010The following is a rather curious promotional video that was shown at the plenary sessions of the AACR 2010 meeting. I first saw it yesterday, and thought my readers might be interested in it while I'm winding my way home:
It's basically a compendium of various facts about cancer and cancer research with a rather obnoxious techno soundtrack to make it "hip" in the way that middle-aged white guys think is "hip." (Believe it or not, the AACR actually played this loud enough to feel the bass.) Annoying music aside, though, the graphics in the video compellingly boil down a large amount of…

Yes, they can! At least Tim Knowles thinks so: he attaches pens to the ends of branches and lets them doodle in the wind, like botanical spirographs.
Knowles says, "Like signatures each drawing reveals the different qualities and characteristics of each tree." It sounds cheesy, but it's true - the drawings really are distinct, and do capture something of the fluidity of a tree in the breeze.
Knowles' body of work is all about distinctive vectors and paths: he also did a series of "Vehicle Motion Drawings", and his "Postal Project" traces, seismograph-like, the movements of a package in…

bioephemera | April 20, 2010That's what I said - you can print skin. Not print on skin, print the skin itself, cell layer by layer. Bioprinting custom skin grafts means you can customize a graft's depth to treat severe burns - using the patient's own cells to avoid rejection.
Kudos to whomever came up with this idea. Seriously: this is bio-DIY to the max. Wow!
Via Armed With Science.
Update: Jason at the Thoughtful Animal just sent me a 2008 minireview on this process by Henmi et al, "New approaches for tissue engineering: three dimensional cell patterning using inkjet technology." It appears to have been sponsored…

Pollen goes unnoticed by most of us, except when hay fever strikes. But microscopes reveal it comes in stunning colors and shapes -- and travels remarkably well. Jonathan Drori gives an up-close glimpse of these fascinating flecks of plant courtship.

bioephemera | April 15, 2010For the past two months, conceptual artist Jonathon Keats has been showing films . . . to potted plants.
Specifically, the flora will be seeing travel documentaries showing off glorious European skies. Will the green cinematic scheme backfire when the plants are too entertained to foresee their possible extinction?"Our destruction of the environment is bad news for plants," the brain-teasing Keats, who also pens Wired's Jargon Watch feature, said in an e-mail interview with Wired.com "I think it's only fair that shrubs and trees know what's happening, that they realize that the cataclysm…

Alan Bur Johnson makes delicate clustered sculptures that consist of transparencies in silver frames mounted on dissection pins: "The installations resemble haiku in their enchanting, simple grammar - and, like precise syllables come to luminous life as each framed, wing-like component flickers independently in the wake of an exhalation or current of air passing through the room." (source).
Much of the fragmented imagery Bur Johnson uses in his transparencies (honeycomb, dragonfly wing venation, segmented legs) is insectoid, and the pieces are correspondingly loose,…

Anthropologie's new From the Deep collection features cobalt blue tentacles reaching over the edge of a dinner plate while an octopus broods on the salad plate.
There are even suckers on the teacup handles!
You can Life Aquatic it up quirky-collage-style with the coordinating dishes featuring collaged fish, stripes, and disproportionately tiny ships, but I'm a purist: I WANT a set of those three tentacular pieces. If I were only getting married so this could be my pattern. . . sigh.

bioephemera | April 11, 2010Something I ran across by accident, while perusing our latest copy of Issues in Science and Technology: currently, the National Academies are sponsoring a Visual Culture and Evolution Online Symposium. It runs through Wednesday. What that means, apparently, is their panelists discuss the intersection of design, art, and culture with evolutionary biology concepts (sexual selection, genetics, adaptation, etc.) at a blog set up for the purpose.
The blog is basic (generic template), and a bit confusing. What seems to be happening is that panelists' ongoing contributions are folded into the posts…

There's a great article at the NYT on the Cocoon, a collection of natural specimens in London's Natural History Museum's Darwin Center. Check out the slideshow to appreciate the juxtaposition of Romanesque architecture with the space-age, egg-shaped exhibition space. Very quirky.
bioephemera | April 10, 2010Skeptvet has created a pithy, albeit cynical, table summarizing what scientists write, what it really means, and what the public thinks it means. I've clipped a little bit of it here, but go to Skeptvet for the whole thing. Nice work!
