“As with many interventions intended to prevent ill health, the effectiveness of parachutes has not been subjected to rigorous evaluation by using randomised controlled trials. Advocates of evidence based medicine have criticised the adoption of interventions evaluated by using only observational data. We think that everyone might benefit if the most radical protagonists of evidence based medicine organised and participated in a double blind, randomised, placebo controlled, crossover trial of the parachute.”

Love this – although disappointing that none were found…
ABSTRACT: Time travel has captured the public imagination for much of the past century, but little has been done to actually search for time travelers. Here, three implementations of Internet searches for time travelers are described, all seeking a prescient mention of information not previously available. The first search covered prescient content placed on the Internet, highlighted by a comprehensive search for specific terms in tweets on Twitter. The second search examined prescient inquiries submitted to a search engine, highlighted by a comprehensive search for specific search terms submitted to a popular astronomy web site. The third search involved a request for a direct Internet communication, either by email or tweet, pre-dating to the time of the inquiry. Given practical verifiability concerns, only time travelers from the future were investigated. No time travelers were discovered. Although these negative results do not disprove time travel, given the great reach of the Internet, this search is perhaps the most comprehensive to date.

The folks over at Urbana-based Electroninks Incorporated just launched a Kickstarter project for a new kind of pen that draws fuctional electronic circuits instantly. Called the Circuit Scribe, the handy little device works like a regular ballpoint pen and releases a non-toxic conductive silver ink that dries instantly.
And I quote:
“If, by some simple and possible means, such as the lessening of the Earth’s magnetic field, which now deflects most of the cosmic rays, they came through in great strength, evolution would go mad.”

Superposition 2013 (entitled Covariance) is a really intriguing looking installation by Lyndall Phelps and Ben Stills and is also now open for visiting (if you’re in London).
“And that’s the hope for our new project Superposition, enabling people to access and engage with physics through art and getting people to think (perhaps just for a minute) about the role physics plays in their lives and the world at large.
This pilot project pairs a physicist (Ben Still) with an artist (Lyndall Phelps) and challenges them to explore physics through the visual arts. The conversations that they have, the ideas that are sparked, and the experiences that they have, will be documented on this blog while the artwork that is conceived between them will be exhibited during the summer of 2013.”
Great humour piece by Sarah Rosenshine. Below is the first paragraph, and I’ve posted it here for archival purposes, but definitely, definitely go read it over at McSweeney’s.
“All right, you found me. Like a subatomic Carmen Sandiego, here I am. Oh, that joke is dated? I’m sorry, everything past the Stone Age is current when you were here at the beginning of time. So please, spare me your inability to comprehend temporal relativity.
Look, I didn’t call you all to the Garden Inn, Geneva so I could trade barbs with CNN’s lone Science and Technology Correspondent. No, I called this press conference for one reason: to ask that you please stop calling me the God Particle.”
