UPDATE:  SOLVED by Amresh at 12:25 CDT

Cogitate!  It’s Saturday, and we get to play.  You’re getting very good at solving these riddles, so just to increase the confusion the subject is slightly more obscure than usual, but you have certainly heard about it.

You ready?  Okay… jumping right in:

Today’s riddle answer is a thing — which happened.

The year this happened was also the year a very special PET was introduced to the world.

This thing/happening is closely linked to the constellation Sagittarius.

Its properties have been heatedly debated.

To our knowledge, this thing has never been repeated.

Something about this is forbidden – and that’s extremely important to consider.

It is, in and of itself, a riddle.

One possible solution to the “real-life” aspect of today’s riddle would strongly impact every person on Earth.

Dr. Seth Shostak could solve today’s riddle in 60 seconds flat, and not just because he’s so smart!

Okay… have I puzzled you?  I’m sure a few people will find this riddle easy (I’m talking to you, Rob and Roger), but I had fun with its creation.  That’s the whole point of these little brain-busters; right?  I hope you have as much fun with its solution.

Enjoy.

I spoke at a Science Blogging Talkfest earlier this week – I had a great time and was honoured to feature on a lot of the attendees’ picks for favourite blog. There’s a transcript of the entire event here as told through Twitter, a nice write-up from Noodlemaz, and an audio recording at some point. In advance of the event, Alice Bell did a set of four great interviews with British bloggers Daniel Macarthur, Imran Khan, Mun-Keat Looi and Jenny Rohn.

I did a photoshoot with some other science journalists for Geekcalendar, a (non-nude) initiative looking to raise money for Libel Reform. Have a look at some outtake photos here.

“Apparently we have learned nothing…” Climate scientists were warned to keep a distance from the media by the IPCC, according to Andy Revkin. They were also sent a “media backgrounder” that’s absolutely fascinating. Chris Mooney illustrates what the letter could have said.

The Earth’s had some work done. She’s now 4.467 billion years old, compared to the previous estimate of 4.537 billion years old. Doesn’t look a shade over 4 billion, but getting a bit oilier of late…

Just 15 of the world’s biggest ships may now emit as much pollution as all the world’s 760m cars, says the Guardian.

Journalism/internet/blogging

The Pepsigate fallout continues with Obesity Panacea and the Primate Diaries leaving too. Check out OP’s new digs and follow Eric on his exile tour. Meanwhile, Abel Pharmboy asks two excellent questions about the farrago, I chip in with comments, and John Pavlus talks about the time he quit ScienceBlogs. And please follow and support some of the excellent writers who have struck out on their own – Skulls in the Stars has the full list but here are my personal picks:

• Brian Switek, Laelaps – tomorrow’s next big thing. Go read him now so you can say you were a fan from the beginning.
• SciCurious, Neurotopia – she loves neuroscience and after reading her talk about it, so will you.
• Alex Wild, Myrmecos – beautiful, beautiful photography
• Rebecca Skloot, Culture Dish – still author of my favourite non-fiction book of all time
• Chris Rowan and Anne Jefferson, Highly Allochthonous – science of rocks that rocks, now in their all-new, easier-to-spell domain
• David Dobbs – insightful musings on neuroscience, genetics, journalism and more
• Daniel Macarthur is still blogging at ScienceBlogs at Genetic Future, but has also formed his own collective called Genomes Unzipped. Definitely worth following.

I love Ben Goldacre’s idea of a unified news repository in which each news story gets a unique ID and anyone can add or upload a full press release or quote to that story’s page, add a link to a primary source, vote these up or down, or add a link to media coverage of that storuy.

A lovely piece by Andrew Marr about why it’s a great time to be a young journalist.

Writers have to read this interview with Rebecca Skloot, which reads like a masterclass in structure and narrative.

Stan Carey jumperates to my defensitation after some readers decide to debate the use of orientate vs orient. Stan’s blog Sentence First is my find of the week. Along similar lines, the Guardian discusses whether ‘data’ is singular or plural.

Oh dear – have scientists solved the chicken or egg problem? No. Thoughtomics and Why Evolution is True tell us why.

“Agreeableness [correlated] with ‘wonderful’ and negatively correlated with ‘porn’.” An analysis of blogger word use, covered in BPS Research Digest.

Should newspapers publish full interview transcripts online? Ezra Klein says, “It’s a no-brainer.” You get incoming links from other niche media sites, you make use of the web’s lack of space limitations and you prove transparency.

Blogging isn’t dead, says Cory Doctorow. I agree. Look, I’m doing it right now…

While I was at The Amaz!ng Meeting 8, attendee Scott Carnegie (from the Winnipeg Skeptics) grabbed a moment with me to ask me which of the ways the world might end would look coolest from the ground. Here’s what I said:

I sometimes wonder what it would be like to be able to actually see a comet in the sky, and know that in some amount of time, months say, it will 100% for sure and for real hit the Earth. What would happen? Riots? Panic? Or acceptance? Probably disbelief until the last minute, and then panic.

Yikes. Good thing there’s nothing out there so far that can hit us. But that day may yet come… and I hope by then we have a space program in place that can take care of it.
