New carbon dioxide molecule found to heat Venus more

The green planet may tell us more about how the greenhouse effect worksA big team of astronomers studying Venus’ atmosphere have found a new type of heavier carbon dioxide molecule that absorbs more heat than the one more commonly found on Mars or Earth. The molecule, which is believed to have two additional neutrons in one of its oxygen atoms, allows it to absorb an additional infrared wavelength of 3.3 microns, which is what tipped the teams off to the discovery. They believe this is part of the reason Venus has such a hot atmosphere – the bigger percentage of these molecules creates an even bigger Greenhouse Gas effect than normal CO2.

As soon as I read this article comparing Mars’ cold atmosphere to Venus’ hot one in relation to the quantities of this new molecule, I immediately thought of Kim Stanley Robinson’s ‘Red Mars’. If this gas contributes more global warming than normal CO2, in the future it may be a very valuable tool if we ever came to terraform our red neighbour.

Friday Free Fiction for October 12th

There may be late arrivals that I’ve missed this week, as my writing duties elsewhere mean I’ll probably be at an album launch party at a dingy music-venue bar somewhere in London when this post goes live … I know, it’s a dirty job, but someone has to do it! 🙂 Any fiction that appeared too late for me to compile will be rolled into next week’s post.

Any which way, it’s a thin week – so remind writer friends and editors of webzines to send me an email about new material, or just do so on their behalf. So, here we go:

***

Project Gutenberg adds stories from Stanley G. Weinbaum: "The Ideal", "The Point of View", "Pygmalion’s Spectacles" and "The Worlds of If".

***

If you’ve any sense, you’re probably checking back regularly or subscribed via RSS, but for those who aren’t in the know, Subterranean Online has added stories by David Prill and Chris Roberson to its latest ongoing edition.

***

Not quite fiction in the traditional sense, but worth a look anyway – Steampunk Magazine‘s Guide to the Apocalypse is available as a free PDF download.

***

Paul McAuley has posted the first three chapters of his latest novel, Cowboy Angels, for you to try out.

An email arrived from Fred Himebaugh:

"I’m writing a series of SF fiction openers as an exercise, and blogging them.  Although the posts are nominally openers, the effect is quite similar to flash fiction, so I think your readers will enjoy them as stand-alone stories.  I’m adding new stories at the rate of two or so per day, and I intend to keep at it for at least a week.

My blog’s topics are science fiction, choral music, choral music in science fiction, and science fiction in choral music.  And zeppelins."

An interesting blend of topics, for certain. Cheers, Fred!

***

Martin McGrath makes the only confirmed appearance from the Friday Flash Fictioneers by having posted "Another Funny Thing Happened in Hyperspace" a few days early. But I’m confident that the usual suspects will provide in their usual reliable manner, so go and check for some fictional nuggets from Gareth L Powell, Gareth D Jones, Neil Beynon, and Shaun C Green. If all has gone according to plan, my piece called "Harvest for the Gods" should be available too.

Have a good weekend!

Allen Telescope Array (ATA) Is Now Online

ata_small.jpgOn Thursday, October 11, in a remote northeast corner of California, technology innovator and Microsoft co-founder Paul Allen officially “turned on” the Allen Telescope Array (ATA).” The telescope array is the first one ever designed from the ground up to efficiently scan targeted stars for alien signals. Within two decades, it will increase the number of stellar systems examined for artificial emissions by a thousand-fold.

CIA director investigates his own investigator, may start using doublethink

In a bizarre case of Orwellian doublespeak, the CIA director today announced that he was going to investigate… the man in charge of investigating the CIA director. Inspector General John L. Helgerson and his office are responsible for oversight and internal investigation of the intelligence agency. Over the last few years a series of intelligence blunders has led the office to take a higher profile than usual, including work on extraordinary rendition, unauthorised wiretapping, torture methods at Abu Graib and Guantanamo Bay as well as the calamity of the Plame Affair and criticism of the agency in the lead up to 9/11.

This story is so bizarre it leads my head in circles, making me feel like I’m in a Phillip K. Dick novel. So the director is investigating the inspector general who is investigating the director… Now we just need the news tomorrow that the inspector is mounting a counter investigation into the investigation of his investigating and besides, what is Ubik?

Thought-controlled avatars for Second Life

Second Life avatars While it may obviously be some time before this technology becomes widely available to the average consumer, I’m fascinated to see a Japanese team of scientists developing a thought-control interface device that can direct the movement of a Second Life avatar. Something like that could really revolutionize the platform … although given the slightly hysterical media reports of, er, dubious pastimes in the virtual world, I’m sure people will leap to conclusions about why users would want their hands free … [Image by Pathfinder Linden]
