I like the lies-to-children motif, because it underlies the way we run our society and resonates nicely with Discworld. Like the reason for Unseen being a storehouse of knowledge - you arrive knowing everything and leave realising that you know practically nothing, therefore all the knowledge you had must be stored in the university. But it's like that in "real Science", too. You arrive with your sparkling A-levels all agleam, and the first job of the tutors is to reveal that what you thought was true is only true for a given value of "truth".
Most of us need just "enough" knowledge of the sciences, and it's delivered to us in metaphors and analogies that bite us in the bum if we think they're the same as the truth.
The only difference between screwing around and science is writing it down

Most researchers don’t share their data. If you’ve ever read the words “data is available upon request" in an academic paper, and emailed the authors to request it, the chances that you'll actually receive the data are just 7 percent. The rest of the time, the authors have lost access to their data, changed emails, or are too busy or unwilling.

Scientific results today are as often as not found with the help of computers. That’s because the ideas are complex, dynamic, hard to grab ahold of in your mind’s eye. And yet by far the most popular tool we have for communicating these results is the PDF—literally a simulation of a piece of paper. Maybe we can do better.
6M observations total! Where has iNaturalist grown in 80 days with 1 million new observations? Citizen science app iNaturalist is seeing explosive growth at the moment—they’ve been around for nearly a decade but 1/6 of the observations posted to the site were added in just the past few months. Having tried the latest version of their iPhone app it’s easy to see why: snap a photo of some nature and upload it to the app and it will use surprisingly effective machine learning to suggest the genus or even the individual species. Submit the observation and within a few minutes other iNaturalist community members will confirm the identification or suggest a correction. It’s brilliantly well executed and an utter delight to use.

arxiv-vanity (via) Beautiful new project from Ben Firshman and Andreas Jansson: “Arxiv Vanity renders academic papers from Arxiv as responsive web pages so you don’t have to squint at a PDF”. It works by pulling the raw LaTeX source code from Arxiv and rendering it to HTML using a heavily customized Pandoc workflow. The real fun is in the architecture: it’s a Django app running on Heroku which fires up on-demand Hyper.sh Docker containers for each individual rendering job.

Color Survey Results. XKCD asked anonymous netizens to provide names for random colours. The results (collated from 222,500 user sessions that named over 5 million colours) are fascinating.
Scott and Scurvy. Did you know that Scott’s 1911 expedition to the south pole was plagued by scurvy, despite the British navy having discovered an effective cure way back in the 18th century? A fascinating tale of how scientific advances can lead to surprising regressions.
The magic of sub-editors. A neat illustration of how sub-editors work their magic, using the original article with strikes through the parts that were edited out.
Locations of Ancient Woolworths Stores follow Precise Geometrical Pattern. Excellent send-up of shoddy science reporting.

The Worst Ideas of the Decade: Vaccine scares. “The movement blaming vaccines for causing autism emerged in the early 2000s, and it was one of the most catastrophically horrible ideas of the decade.”
Algae and Light Help Injured Mice Walk Again. Optogenetics is a rapidly growing field which uses viruses to implant genes from plants in to neurons and enable them to be controlled by blue and yellow light. In the lab it’s made mice run in circles without causing any apparent long-term damage, and the technology has the potential to provide a read/write interface to the human brain itself.
How Grandmas May Give Kids an Evolutionary Edge. Absolutely fascinating: XY v.s. XX chromosomes mean that paternal grandmothers have a 50% chance of sharing an X with their son’s daughters, but a 0% chance of sharing an X with their son’s sons. A study on survival rates of 43,000 children found a corresponding correlation with the proximity to a paternal or maternal grandmother. Men: Dad’s Mum is out to get you!
10 Uses for Blocks in C/Objective-C. Part of the Cocoa for Scientists series, which is by far the best free Objective-C / Cocoa tutorial I’ve seen anywhere.
Python in the Scientific World. Python continues to make strides in the scientific world—and the Hubble Space Telescope team have been using it for 10 years!
Quack Remedies Spread Faster *Because* They Don’t Work. “... because (a) most people eventually get better on their own (and then blame it on the treatment), but (b) people adopt treatments based primarily on what they see other people doing, rather than by looking at scientific evidence. Basically, the longer you stay sick, the more time other people have to imitate you.”

Imaginary numbers. “We would like to back up our survey with an equation from an expert to work out which celebrity has the sexiest walk, with theory behind it”—Ben Goldacre provides inside information on how PR firms invent science to back up their campaigns.
A study of the Galaxy Song by Eric Idle. More than twenty years later, the science of the Galaxy Song from Monty Python’s Meaning of Life mostly still holds.
Encyclopedia of Life. Ambitious, well funded project to create a professionally maintained Wikipedia for species. I really hope they get their URL design right.
United Nuclear (via) Gotta love an online store that stocks both “Misc Radioactive Items” and “Anti-Radiation Pills”.
