- Endogenous steroids and financial risk taking on a London trading floor (PNAS) — We found that a trader’s morning testosterone level predicts his day’s profitability. We also found that a trader’s cortisol rises with both the variance of his trading results and the volatility of the market. Our results suggest that higher testosterone may contribute to economic return, whereas cortisol is increased by risk. Our results point to a further possibility: testosterone and cortisol are known to have cognitive and behavioral effects, so if the acutely elevated steroids we observed were to persist or increase as volatility rises, they may shift risk preferences and even affect a trader’s ability to engage in rational choice.
- The Origin of Universal Scaling Laws in Biology — eye-opening paper that blew my mind. Highlight of Sci Foo was meeting the author and shaking his hand. Relates metabolic rate, size, heart rate, and lifespan by applying physics to biology.
- Ushahidi — open source software for managing disasters. The Ushahidi Engine is a platform that allows anyone to gather distributed data via SMS, email or web and visualize it on a map or timeline. Our goal is to create the simplest way of aggregating information from the public for use in crisis response.

Dissecting the Canon: Visual Subject Co-Popularity Networks in Art Research — In this paper we analyze a classic da-
taset of art research, which collects ancient art and architecture and their Western
Renaissance documentation since 1947. [T]here is clearly a long tail of monument
popularity.

A great free book, dead newspaper dig, movie Torrent wakeup, and money from free:
- Digital Foundations with Adobe Illustrator — CC-licensed book that gets you started using Adobe Illustrator. I’m loving it, and I have the artistic ability of a particularly philistine rock. See also their advice to authors on how to negotiate a Creative Commons license. (via bjepson’s delicious stream)
- How to Become a Death Of Newspapers Blogger — tongue-in-cheek dig at the recent imminent deaths of newspapers being predicted. Point taken about how unproductive these are: The point’s not to fix anything. It’s to describe the problem more dramatically than the next guy. If Steve Outing says newspapers have a “death spiral” and Clay Shirky predicts “a bloodbath,” the point goes to Shirky. Basically, imagine a group of people watching a building burn down and bickering amongst themselves about whether it’s a conflagration or an inferno. It’s like that, but with consulting fees. (via migurski’s delicious stream)
- BarTor, Android BitTorrent with a Twist — take a picture of a DVD’s barcode, it looks up the movie, and sends the torrent file to your desktop to be automatically downloaded. NetFlix should have a legit form of this. If iTunes Movie Store had it, you could have racks of “DVDs” in stores that you could browse and snap to “buy” (giving a cut to the store). This feels monumental.
- Survey of Free Business Models Online — an interesting breakdown of ways to make money from “free” on the web. (via glynn moody)
Marc Bohlen: Finding the Intersection of Art and Technology
Artist-Engineer Marc Bohlen uses some fairly advanced technology to express his artistic visions. It's not often you find an artist with a degree from CMU in robotics, or an engineer with an Masters in Art History. Bohlen's projects explore how people and technology interact, ranging from the bickering robots Amy and Klara, to his latest project, the Glass Bottom Float. In advance of his appearance at the E-Tech conference in March, Bohlen talked to us about how he approaches art, and just what art is.

Art, astronomy and more fun for you in today’s four short links:
- Found in Space — there’s an astronomy bot on Flickr that identifies stars in the night sky, and from the unique positions of the stars figures out what bit of the night sky is looked at and then adds notes for interesting parts of the sky visible in the shot. A brilliant use of computer vision techniques to add value to existing data. (via Stinky).
- 99 Secrets Twittered — Matt Webb is posting a secret a day from Carl Steadman’s 99 Secrets, an early piece of art on the web. Matt’s explanation is worth reading. Ze Frank really made me realize that every web app is a medium for art, for provoking human responses, and now I keenly watch for signs of art breaking out.
- Internet Ephemera — a brief muse on “if we start with the assumption that everything we put online is ephemeral, how does that change what we put online?”
- Pockets of Potential (PDF) — a 52-page PDF talking about opportunities for supporting learning with the mobile devices already in kids’ lives (via Derek Wenmoth).

Hello from Whakapapa, a ski resort in New Zealand. These four links come to you via the wifi at the “highest hotel in New Zealand“, which serves as a useful reminder that no matter how unremarkable one might seem, anyone can have a claim to fame if only they work at it.
- Apple Show Us DRM’s True Colors – the EFF checks out where Apple has DRM in its products and discovers that in most cases it has little to do with piracy and more about eliminating legitimate competition. DRM is “bundling” for the 2000s. (via stinky)
- Rules of Database Aging – this is so true. I think everyone who read this said, “this is so true”. Cue Santayana quote.
- Blog Converters Released – apparently Google has Data Liberation Front that has released a converter to let you switch between Blogger, LiveJournal, MovableType, and WordPress formats for blog archives. When they add Twitter, they might make Tim Bray feel better about Twitter. (via waxy)
- Hana – an absolutely beautiful screensaver for OS X (other platforms soon, I hope) that simulates every flower it shows. I could try to justify this as tied into the growing trend of simulations as the skills of simulation drive more fields of life, but really it’s just pretty. And who doesn’t need a drop more pretty in their life?
