Back in February, I went to the American Association for the Advancement of Science conference in Chicago. The whole thing was pretty much a geeked-out blast, but one of my favorite sessions was this four-hour long symposium, the crux of which can basically be summed up as, "Evolution: It Works, Bitches." This particular tidbit, which I originally heard there in a lecture given by Brown University biology professor Kenneth Miller, is just totally nifty and must be shared.
So here's the thing: We have 46 chromosomes. Our nearest great ape relatives have 48. On the surface, it looks like we must have lost two. But that's actually a huge problem. Made up of organized packs of DNA and proteins, chromosomes don't just up and vanish. In fact, it's doubtful any primate could survive a mutation that simply deleted a pair of chromosomes. That's because chromosomes are to the human body what instruction sheets are to inexpensive, Swedish flat-pack furniture. If you're missing one screw, you can still put that bookcase together pretty easily. But if the how-to guide suddenly jumps from page 1 (take plywood panels out of box--uff da) to page 5 (enjoy bookcäse!), you're likely to end up missing something pretty vital. All this left scientists with a thorny dilemma: How could we have a common ancestor with great apes, but fewer chromosomes?
Turns out: The chromosomes aren't missing at all.
Genetic investigators caught the first whiff of the prodigal chromosomes' scent in 1982. That year, a paper published in the journal Science described a very funny phenomenon. Researchers knew all chromosomes had distinctive signatures; patterns of DNA sequences that can be reliably found in specific spots, including in the center and on the ends. These end-cap sequences are called telomeres. Molecular biologist Elizabeth Blackburn says telomeres are like the little plastic tips that keep your shoelaces from unravelling. They protect the ends of chromosomes and hold things together. Given that important function, you wouldn't expect to find telomeres hanging out on other parts of the chromosome. But that's exactly what the 1982 study reported. Looking at human chromosome 2, the scientists found telomeres snuggled up against the centromere--the central sequence. What's more, these out-of-place human telomeres were strikingly similar to telomeres that can be found, in their proper location, on two great ape chromosomes.
This evidence laid the groundwork for a brilliant discovery. Rather than falling apart, the two missing chromosomes had fused together. Their format changed, but they didn't lose any information, so the mutation wasn't deadly. Instead, scientists now think, the fusion made it difficult for our ancestors to mate with the ancestors of chimpanzees, leading our two species to strike out alone. In the two decades since the original study, more evidence has surfaced backing this up, which leads us to 2005, when the chimpanzee genome was sequenced around the same time that the National Human Genome Research Institute published a detailed survey of human chromosome 2. According to Kenneth Miller, we can now see extra centromeres in chromosome 2 and trace how its genes neatly line up with those on chimpanzee chromosomes 12 and 13. It's a great example of evidence supporting the common descent of man and ape.
I'm currently in the process of putting together a mental_floss story looking at this, and several other awesome experiments revolving around the origins of life. I'm not sure yet when it will be published, but, obviously, I'm really excited about it.

The Arduino Mega in the Maker Shed is the latest micro-controller from the Arduino team. The Mega is built around the ATmega1280. It's perfect for anyone looking for more room for code or to be able to control a lot more LEDs, sensors, servos, or motors. It has 54 digital input/output pins (of which 14 can be used as PWM outputs), 16 analog inputs, 4 UARTs. Another great feature is the Arduino Mega is compatible with most shields designed for the Arduino Duemilanove or Diecimila.

The doctrine of unclean hands and basic principles of equity prohibit The AP from contending that Counterclaim Defendants' Obama Works infringe The AP's copyrights when The AP itself exploits the copyrighted work of Fairey and other artists without permission and in a manner that is far less transformative than the Obama Works, as illustrated but not limited to, the photographs listed above.It seems this battle is getting nasty. Of course, while making these claims may feel good, it's hard to believe that they'll be all that compelling. The AP will clearly claim that its photos of these pieces of artwork were fair use, as part of news commentary. But, that's probably part of the point being raised by Fairey's legal team. It's unlikely to believe that the AP really abused Fairey's copyright or the copyrights of these other artists, but if it can get the AP defending its acts on fair use principles, then they can easily use the AP's words against it, in explaining why Fairey's image is also covered by fair use.

When the developed world gets over its bias for "printing press–era cash technology" then complementary currencies will be commonplace here too, Rushkoff predicts. He sees a future that has people literally reprogramming their economic systems, using computer networks and handheld devices to administer new forms of grassroots cash. Those currencies could be almost anything: Cash we can use only at one local restaurant, cash cards for Wal-Mart or other chain stores, babysitting dollars we can trade in our neighborhoods."The Future of Money: DIY Currencies"
There are some small examples of people of this future here now. In Japan, people trade “elder-care units,” which are measured in time spent caring for elders in the community, and they've become quite valuable as the population in that country ages. In the United States, hours of service are exchanged via the online Time Bank or locally in Ithaca, New York. Then there are the “Life Dollars,” an electronic currency used in the Pacific Northwest. The experiments have been successful, albeit quite small. The total amount of Ithaca hours in circulation is $100,000, while Life Dollars are used for perhaps $2,000 worth of transactions per month.
Newmark isn't sold on the "craigbucks" idea, but that isn't stopping Rushkoff. "If he doesn't want to do it, I can do it myself," he says with a laugh.

Video: Bill O'Reilly gets wise to Super Mario Discuss this on Boing Boing Offworld![]()
Bill O'Reilly and his
PeabodyPolk award winning crew at Inside Edition report on the emerging world of Nintendo, at a time when the Mario name meant Puzo more than plumber.As a bonus, a look behind the scenes at Game Counselor HQ, and another teasing glance at that gold-covered 'Zelda Tips and Tactics' booklet that used to sing its (too expensive for a pre-teen) siren song to me from every. single. issue. of Nintendo Power.
Today on Offworld, Ragdoll Metaphysics columnist Jim Rossignol takes a deeper look at the recently much-hyped promises of "cloud gaming" services like OnLive and Gaikai -- who suggest that the days of buying powerful home processing hardware are numbered if our games were processed on the cloud and delivered via video streaming -- and a look at what questions and concerns remain when the fantastic claims seem more reasonable in a few years time.
We also took a technical look into the five year development of Maxis' Spore via an exhaustive set of "liner notes" written by technology lead Chris Hecker (seen left, his very first created Spore creature) as well as art director Ocean Quigley's own blog, and played Don't Save The Princess, today's best indie PC game.
Elsewhere we saw Bill O'Reilly discover the new world of Nintendo via a 1988 broadcast, imagined how Bioshock should have ended, saw a fantastic new LUA hack for Super Mario Bros 3 where all control of the game is given to painted-on rainbow stripes, and ordered a set of ruggish Pac-Man half-sized knuckle dusters.
Finally, we played a game where Daft Punk seek their samples stolen by rival electro-duo Justice, pre-ordered adorable official Bubble Bobble shirts and ordered more wearables via the new Edge magazine shop, and, best of all, watched the latest video from pop duo Boy in Static created entirely with TextEdit and ancient .gif clipart -- and then played a game based on the same.
Police delete London tourists' photos 'to prevent terrorism' (Thanks, Matt!)But the tourists have said they had to return home to Vienna without their holiday pictures after two policemen forced them to delete the photographs from their cameras in the name of preventing terrorism.
Matkza, a 69-year-old retired television cameraman with a taste for modern architecture, was told that photographing anything to do with transport was "strictly forbidden". The policemen also recorded the pair's details, including passport numbers and hotel addresses.
In a letter in today's Guardian, Matzka wrote: "I understand the need for some sensitivity in an era of terrorism, but isn't it naive to think terrorism can be prevented by terrorising tourists?"
The Metropolitan police said it was investigating the allegations.
In a telephone interview from his home in Vienna, Matka said: "I've never had these experiences anywhere, never in the world, not even in Communist countries."

The source close to Fairey's legal affairs who passed these directs our attention to a section which, in their words, "illustrates the hypocrisy of the AP." This section documents a number of instances in which Shepard's defense argues the AP has published -- and profited from -- Fairey's work, and that of other artists, without obtaining a license.
# On January 7, 2009 The AP distributed a story entitled "Iconic Obama portrait headed to Smithsonian museum" by Brett Zongker. The AP's article included a photograph attributed to The AP, which depicted Fairey's Obama Hope Stencil Collage that now hangs in the National Portrait Gallery of the Smithsonian Institution. (A copy of the full article is attached as Exhibit A and available at [link].) The AP did not obtain a license to use Fairey's work in this photograph. As shown below, the photograph attributed to The AP consists of nothing more than a literal reproduction of Fairey's work.
# The AP's image database contains the following photograph of Jeff Koons' sculpture entitled Ushering In Banality. On information and belief, The AP did not obtain a license to use Koons' work in this photograph.
# The AP's image database contains the following photograph of George Segal's The Diner. On information and belief, The AP did not obtain a license to use Segal's work in this photograph.
# The AP's image database contains the following photograph of Banksy's Di-Faced Notes. On information and belief, The AP did not obtain a license to use Banksy's work in this photograph.
# The AP's image database contains the following photograph of Keith Haring's Hope. On information and belief, The AP did not obtain a license to use Haring's work in this photograph.

Update: A statement from the Associated Press follows, after the jump.
Paul Colford, Director of Media Relations for The Associated Press, emailed this statement to Boing Boing:
Statement from The Associated Press:The Associated Press is still in the process of reviewing Mr. Fairey's response to its Counterclaims, but it is very revealing that rather than present any evidence to justify his own obvious misappropriation of the AP's copyrighted work, he instead focuses on making collateral attacks on the AP, one of the oldest and largest news organizations in the world, regarding standard newsgathering activities. Even more disappointing is the fact that Mr. Fairey appears to have deliberately omitted from his filing information regarding the newsgathering context in which the various images were generated and in which they are used. We note that Mr. Fairey admits that he engaged in the hypocritical conduct discussed in the AP's Counterclaims, including using the work of others without obtaining a license while at the same time threatening others for using his own works.

This catapult-style tennis ball launcher is my first attempt. I'm sure there's an engineering principle that covers this kind of machine, but I am uninformed, so bear with me. The shredder motor winds the elastic band until it gains enough potential energy to start the arm moving. Once the arm starts, it accelerates quickly and slams into the forward stop, throwing the ball. I have fitted the arm with a second, weaker elastic band which tensions as the arm reaches the forward stop. When the direction of the motor is reversed, the tension is released from the main elastic band, allowing the second band to return the arm to its resting position.Except for the wood frame, the launcher is made of scavenged parts from:
- dead paper shredder
- old SCSI scanner
- Theraband that my Physical Therapist gave me (yep, shoulder)
- slingshot-style tennis ball launcher
- Chuckit tennis ball thrower
- 55 gallon plastic barrel
- cardboard box
I threw the whole thing together in about 2 hours and was surprised when it worked on the first try. The ball currently travels about 30 feet, which is far from ideal as my goal is 200 feet. Relays are on the way for the motor control and I have a Make Controller sitting here waiting for firmware.

Take Part in one of the Summer's Most Innovative Creative Writing Programs for Teens. (Thanks, Matt!)
Shared Worlds, an innovative two week workshop in fantasy and science fiction worldbuilding is currently seeking applications for attendance from students grade eight to twelve who have an interest in creative writing and fantasy worldbuilding.The program is held from July 19 through August 1 on the campus of Wofford College in Spartanburg, SC, and offers an intensely creative atmosphere in which students learn all aspects of building their own fictional world through instruction in creative writing, history, art, philosophy and physics and then apply that knowledge by creating fiction, games and more.
This year's instructors include assistant director and two time World Fantasy Award winning author Jeff VanderMeer, Weird Tales fiction editor Ann VanderMeer, role playing game designer Will Hindmarch, Spiderwick Chronicles creator Holly Black and New York Times bestselling author Tobias Buckell, plus Wofford College's own Dr. Christine Dinkins, philosophy professor, and Jeremy Jones, lecturer and camp director.
Although the emphasis of this think tank for teens is on fantasy, according to Jeff VanderMeer the things that the participants learn will be very useful in real life.

Yes: nuclear waste. As soon as the government was gone, mysterious European ships started appearing off the coast of Somalia, dumping vast barrels into the ocean. The coastal population began to sicken. At first they suffered strange rashes, nausea and malformed babies. Then, after the 2005 tsunami, hundreds of the dumped and leaking barrels washed up on shore. People began to suffer from radiation sickness, and more than 300 died.Johann Hari: You are being lied to about pirates (via Isen)Ahmedou Ould-Abdallah, the UN envoy to Somalia, tells me: "Somebody is dumping nuclear material here. There is also lead, and heavy metals such as cadmium and mercury - you name it." Much of it can be traced back to European hospitals and factories, who seem to be passing it on to the Italian mafia to "dispose" of cheaply. When I asked Mr Ould-Abdallah what European governments were doing about it, he said with a sigh: "Nothing. There has been no clean-up, no compensation, and no prevention."
At the same time, other European ships have been looting Somalia's seas of their greatest resource: seafood. We have destroyed our own fish stocks by overexploitation - and now we have moved on to theirs. More than $300m-worth of tuna, shrimp, and lobster are being stolen every year by illegal trawlers. The local fishermen are now starving. Mohammed Hussein, a fisherman in the town of Marka 100km south of Mogadishu, told Reuters: "If nothing is done, there soon won't be much fish left in our coastal waters."
This is the context in which the "pirates" have emerged. Somalian fishermen took speedboats to try to dissuade the dumpers and trawlers, or at least levy a "tax" on them. They call themselves the Volunteer Coastguard of Somalia - and ordinary Somalis agree. The independent Somalian news site WardheerNews found 70 per cent "strongly supported the piracy as a form of national defence".
No, this doesn't make hostage-taking justifiable, and yes, some are clearly just gangsters - especially those who have held up World Food Programme supplies. But in a telephone interview, one of the pirate leaders, Sugule Ali: "We don't consider ourselves sea bandits. We consider sea bandits [to be] those who illegally fish and dump in our seas."
"The greatest success of PATExpert has been to initiate the change of the paradigm currently followed in patent processing services from textual to semantic."It would be great if someone could explain that in plain English, because it sounds like gibberish trying to sound intelligent. But, back on point, it's hard to see how any "automated" system would actually help in the process of approving patents. Considering how many mistakes are made and bad patents allowed through, I'd worry that automating the process is only likely to create significantly more problems.
Here's a talk I gave earlier this year at the O'Reilly Tools of Change for Publishing conference in NYC, about the way that DRM gives distributors control over publishers and writers. This talk went down very well, and is the source of "Doctorow's Law," which a lot of people have asked me about: "Any time someone puts a lock on something you own, against your wishes, and doesn't give you the key, it's not being done to your benefit."
There's some errata here, though: the Overdrive debacle was due to a licensing dispute, not a bankruptcy; and there's now a "DRM-free" option for the Kindle, but I can't find out if the file comes with legal encumbrances that would prevent people who buy one of these from moving it to a competing device (no one at Amazon will answer my queries about this). And I've also been told by Amazon that supposedly Audible will do DRM-free audiobooks, but they haven't answered repeated queries about the details of this.

So one of the chapters in Be Amazing is dedicated to teaching you how to be a better mooch. Naturally, the focus is on parasites.
Just focus on that cute little, panhandling filarial worm, while I tell you about something far less adorable.
Sacculina are one of those creatures that are both absolutely fascinating and also relatively decent evidence against the existence of a loving deity. Think of them as nature's equivalent of Dracula, on the hunt for a Renfield.
Actually more of a barnacle with a parasitic bent, the sacculina starts out life as a weensy, free-floating organism, swimming about the seas. Although she spends her early life footloose and fancy-free, what the female sacculina really wants is to meet a nice crab and settle down. What the crab wants never really factors into the equation.
Once she finds a suitable crab, the sacculina swims around to the belly of the shellfish and, using a sharp hollow point on her exoskeleton, injects herself into the crab's flesh, leaving behind an empty husk. Inside the crab, the sacculina begins to take over, burrowing long, nutrient-sucking tendrils into every part of the crab's anatomy, from the eyestalks to the claws. As she does this, the sacculina changes the crab's behavior; effectively neutering it, preventing it from growing and winnowing down its once-vast list of interests to a single hobby: Eating. After the sacculina picks up a mate or two, the crab will even spend what little energy resources it has helping to tend her baby parasites and giving them a good start in the world. Now entirely under her control, the crab ends up living only to serve the sacculina and help her and her family infect other crabs.

For the record, I am not advocating running out and killing you off a species. No, not even S. coleoptrata. I see these as sort-of cautionary tales of how human plans can go horribly, horribly wrong for the denizens of the animal kingdom. Yes, this is an excerpt from Be Amazing, but one can learn the art of fabulosity from the mistakes of others, as well as from their triumphs.
That disclaimer accomplished, let's get on to the good stuff.
Method 1: Through Gluttony
There used to be hundreds of thousands of giant tortoises roaming (slowly) about South America's Galapagos Islands. Today, there are roughly 15,000. What can we say? Turtles are tasty. In the 16th and 17th centuries, the Galapagos were the swashbuckler's equivalent of a 7-Eleven--the last chance to stock up on food before hitting the vast emptiness of the Pacific. Besides being sluggish and docile (i.e., easy to catch) the tortoises could also survive for up to a year without food or water. Sailors often captured hundreds at a time, stacked them on their backs and, thus, had fresh meat all the way to India.
Method 2: Out of Sheer Hatred
Passenger pigeons once traveled around the United States in flocks so large, they could reportedly block out the sun over a town for eight hours. In the process, they gobbled down all the fruits and grains they could get their beaks on and left the "remains" for farmers to step in. All this made them rather ... unpopular. Throughout the 19th century, killing passenger pigeons was basically the national pastime. Baited with alcohol-soaked grain, gassed with sulfur fires and loaded live into trapshooting launchers (they were later replaced with clay "pigeons"), the passenger pigeon population quickly petered out. The last one died in the Cincinnati Zoo on Sept. 1, 1914.
Method 3: Via Tragicomic Irony
Collector and proto-environmentalist Rollo Beck visited the island of Guadalupe, off Baja California, on December 1, 1900. During the trip, he sighted a flock of nine Caracaras, a rare bird he wished to study (apparently in taxidermied form), and so he shot down all but two of them. Those two turned out to be the last Caracaras ever seen alive.
It's really sad about the Caracaras, but the passenger pigeons kind of had it coming.

Today's been a hectic day, so I'm behind in getting up this Maker Birthday tribute to probably the maker of all makers. To me, Leonardo is the ultimate example of what you might call the Bucky Fuller Challenge. In 1927, Fuller at 32, was suicidal. Instead of leaping from the bridge on which he stood, ready to take his life, he decided to give the rest of that life to the world, to challenge himself to see what "a single intelligence unit" could accomplish in a lifetime.
In my William Blake piece in the latest MAKE, I relate Blake's view that the human imagination is infinite, divine, and that we tragically hobble our access to that imagination and from all that we're capable of. When you look at giants like Da Vinci, William Blake, and Buckminster Fuller, it does give you pause to consider what we all might be able to accomplish if we could find full-on access to that current of imagination and innovation.
If you want to get a glimpse of what "Human Intelligence Unit Leonardo" was able to accomplish, check out the official Leonardo website (where all the pictures below came from). It is absolutely mind-boggling, page after page after page of jaw-dropping ideas, inventions, and staggeringly beautiful works of art. There's so much material here and good use of virtual walkthroughs, 3D models, hi-res photos, you could spend days on it. A fittingly-dense and attractive tribute to the man.
Here's the beginnings of the Wikipedia entry on Leonardo:
Leonardo di ser Piero da Vinci (Leonardo di ser Piero da Vinci, April 15, 1452 - May 2, 1519) was an Italian polymath, being a scientist, mathematician, engineer, inventor, anatomist, painter, sculptor, architect, botanist, musician and writer. Leonardo has often been described as the archetype of the renaissance man, a man whose unquenchable curiosity was equaled only by his powers of invention. He is widely considered to be one of the greatest painters of all time and perhaps the most diversely talented person ever to have lived. Helen Gardner says "The scope and depth of his interests were without precedent...His mind and personality seem to us superhuman, the man himself mysterious and remote".
Born as the illegitimate son of a notary, Piero da Vinci, and a peasant woman, Caterina, at Vinci in the region of Florence, Leonardo was educated in the studio of the renowned Florentine painter, Verrocchio. Much of his earlier working life was spent in the service of Ludovico il Moro in Milan. He later worked in Rome, Bologna and Venice and spent his last years in France, at the home awarded him by Francis I.
Leonardo was and is renowned primarily as a painter. Two of his works, the Mona Lisa and The Last Supper, are the most famous, most reproduced and most parodied portrait and religious painting of all time, respectively, their fame approached only by Michelangelo's Creation of Adam. Leonardo's drawing of the Vitruvian Man is also regarded as a cultural icon, being reproduced on everything from the Euro to text books to t-shirts. Perhaps fifteen of his paintings survive, the small number due to his constant, and frequently disastrous, experimentation with new techniques, and his chronic procrastination. Nevertheless, these few works, together with his notebooks, which contain drawings, scientific diagrams, and his thoughts on the nature of painting, comprise a contribution to later generations of artists only rivalled by that of his contemporary, Michelangelo.
Leonardo is revered for his technological ingenuity. He conceptualised a helicopter, a tank, concentrated solar power, a calculator, the double hull and outlined a rudimentary theory of plate tectonics. Relatively few of his designs were constructed or were even feasible during his lifetime, but some of his smaller inventions, such as an automated bobbin winder and a machine for testing the tensile strength of wire, entered the world of manufacturing unheralded. As a scientist, he greatly advanced the state of knowledge in the fields of anatomy, civil engineering, optics, and hydrodynamics.







And, our very own John Park points us to a site he did a few years back on Da Vinci's Kinematic Mechanisms:
I've been interested in creating reproductions of Leonardo da Vinci's machines and automata using 3D software for some time. I'll document the process here as a sort of loose tutorial in rigging mechanical devices.

Sixteen teams gathered today to determine whose autonomously-navigating vehicle would be the fastest around the Sparkfun headquarters in Boulder, CO.
Four-wheeled rovers (typically built on RC car platforms) dominated the entries, but there were three flying UAVs, and one spheroid ("labrat", pictured at right). One team was designing a tethered model rocket to fly the course, but, unfortunately, their entry didn't compete.
The race was structured as 3 heats. Each vehicle got 5 minutes to attempt a run; best time overall won.
The first heat got off to a rough start. About half of the robots made it to the first corner of the building, but only "Mookie Mobile Death Pod 3000" made it around the whole course.
A slight wind from the West seemed to be affecting the UAVs. They also had to deal with the multiple trees. The Boulder Fire Department was kind enough to help out with one, and others were low enough to get by hand. The DIY Drones plane found itself in multiple trees:

The ground-based vehicles had other obstacles to deal with, including curbs, and people who foolishly think that curbs are a safe place to stand.
After nearly hitting its creator, Mookie Mobile Death Pod 3000 goes after innocent bystanders:
Between rounds, people learned from the mistakes from previous runs, and tweaked their robots accordingly. Death Pod 3000, the only robot to complete the course in the first heat, solidified its lead in the second by lowering its time to 1:28. The UAV was incredibly fast, but winds pushed it so that it flew over one corner of the building, disqualifying that run.

In the end, though, the DIY Drones team scored a stunning success with their final try, with Chris Anderson's UAV completing the course in 36 seconds to win the tile!
The competition is over! Diy drones is 1st, with deathpod3000 taking the Engineers Choice award. Thanks for following!!! See you next year!

Minneapolis maker Frank E. Yost shared this beauty of a project with us back in MAKE Volume 11, and it was a definite favorite in the MAKE Labs from the get-go. I mean, who doesn't love sheet metal and pop rivets?
Frank loves R/C toys but doesn't love plastic. He was on the quest for a metal toy racer 10 inches or longer to make into an R/C car, but the best ones he found were all collectibles. In true maker spirit, he decided to build a custom metal body and based his design on tether cars of the 1930s.
This illustration (by the talented Nik Shultz) shows a closer look at the suspension and body from below:

The project is not only sweet because you end up with a beautiful custom Retro R/C Racer, but you even get a built-in mini primer on sheet metal modeling. Check out a bigger view of the illo above and a peek at the whole project in our Digital Edition. Make sure to pick up your copy of MAKE Volume 11 from the Maker Shed if you don't have one already. Volume 11 also includes a special "DIY Wheels" section, with plans for making a mobile drive-in movie theater, a cool chopper out of an old bicycle, and a pedal powered iPod charger, as well as how to make a remote control bird feeder to take amazing photos of birds and a vacuum-former that lets you create molded 3D parts out of plastic.

The fabulous Kasey McMahon of yourpsychogirlfriend.com, whose Compubeaver and Text-o-Possum we featured in early Boing Boing TV episodes, has sent along this amazing photograph of a newly completed work: a fully functional birdcage dress. By "fully functional," I mean that it has birdies in it. There's an Instructables for it, too! Roll your own.
(thanks, Christy Canida and Kasey McMahon)

Annathered has a wonderful, step-by-step HOWTO for creating delicious cream puffs in the shape of Totoro. The photoset is here, and the recipe and assembly instructions are here. (Thanks, Souris!)
Below, the trailer for the '80s Miyazaki anime classic on which the aforementioned dessert is based.

Here it is. And, wouldn't you know it, they have an opinion on the murder conviction delivered to Phil Spector, whom they reveal as one of their own.
[L]et us say this to you now, American dogs: your snipers may take us out with headshots, or your lawyers may frame us for murder. We care not about the methods, and we care less about the results. Because we are not all as easy to find as our fallen comrade who lived in a castle in Los Angeles. Most of our castles are in Somalia, and they are underground, and they are guarded by wild boars who haven't been fed this week.Official Statement on the Phil Spector verdict (somalipirate.livejournal.com, thanks Sean Bonner)
The weekly Lost Knowledge column explores the possible technology of the future in the forgotten ideas of the past (and those slightly off to the side). Each Tuesday, we look at retro-tech, "lost" technology, and the make-do, improvised "street tech" of village artisans and tradespeople from around the globe. "Lost Knowledge" is also the theme of the current issue of MAKE, Volume 17 (on newsstands now)
In this installment of Lost Knowledge, we look at the arcane arts of homebrewing your own electronic components. This column was inspired by Collin's experiments with light-emitting diodes in his Make presents the LED video (see below). I thought it might be fun to collect some of the other homebrew component projects we've covered here on MAKE and that I could find elsewhere.
This is far from comprehensive. If you know of other cool projects of this nature, please add links in the Comments.
Diodes:

Collin's experiments with light-emitting properties in silicon carbide for his LED episode of Make presents.


This is a follow up experiment from the report that I wrote previously about home evacuation of a vacuum tube. The next step is to make my own vacuum tube from scratch. This is my first attempt, a diode. The diode seems to work surprisingly well and makes the thought of putting a grid between the filament and the plate very encouraging.
Triodes
The undisputed king of homebrewed retro componentry is France's Claude Paillard and his made-from-scratch triodes. This guy is like some Franco-geek national treasure. His site is in French, but there's a link to Google Translation (for what that's worth). We've posted this video several times already, but it's worth posting again for anyone who missed it.
