"Modernist Cuisine at Home" Brings a Slightly-More-Affordable Version to the Masses

Modernist Cuisine at Home Pictured is "our fake home kitchen that we built in our photography studio, just down the hall from our research kitchen at The Cooking Lab," says Scott of Modernist Cuisine Modernist Cuisine

The groundbreaking Modernist Cuisine isn't exclusively for expert chefs, but the price and heft (~$450, extremely hefty) take it out of reach for most regular people. Enter Modernist Cuisine at Home, a newly announced new book that takes much of the goodness of the original six-volume set and adapts it for the home cook--along with over 400 new recipes.

The new 456-page Modernist Cuisine at Home has "all the essential information that any cook needs to stock a modern kitchen, to master Modernist techniques, and to make hundreds of stunning recipes." It also comes with a waterproof 230-page "Kitchen Manual" that has every recipe reprinted for easy, safe use.

The new recipes are definitely geared more towards home cooks, which means Myhrvold, Chris Young, Maxime Bilet and the rest of the ModCuis team have included a lot more comfort food than in the original book. There's a chapter on mac and cheese, a recipe for boneless chicken wings, one for a lobster roll, a whole section on microwave cookery, and more. Oddly, there's still no hint of a possible tablet version--I've been wanting an iPad Modernist Cuisine since we heard of the project, and continued wanting it while reading Paul's exploration of pea butter, his tour of Modernist Cuisine's lab equipment, and his home centrifuge experiment. Looks like I'm still waiting--and might be for awhile, since Myhrvold has spoken in the past about not being satisfied with tablets and wanting to completely rethink the book before releasing a tablet version, but in the meantime, you can pre-order the new book now (it'll cost around $140, though Barnes & Noble has it for $112--still pricey for a cookbook, but at least a little more affordable) to receive it when it's released on October 8th.

Tomato Genome Decoded, Will Seed Development of Tastier, Fleshier Fruits

A relatively small cluster of genetic information, some of it dating to 60 million years ago, endows the staple fruit of summer with its taste and texture. The secrets of the tomato, star of summer gardens, salads and gazpacho, is now laid out for plant breeders and horticulturists in exacting detail.

Adding to a growing list of plant gene maps, the Tomato Genome Consortium today published genome sequences for two tomatoes: The "Heinz 1706" varietal, an inbred cultivar that serves as a model for the domesticated tomato, and its closest wild counterpart, Solanum pimpinellifolium. The nine-year effort provides the closest glimpse yet of the 35,000 genes and 12 chromosomes of tomatoes, and by extension the rest of their extended plant family. The two sequences also tell the story of tomato domestication, notably its initial cultivation in the Americas and the introduction of "pomo d'oro" to the Old World in the 16th century.

The sequences provide new insight into the genes responsible for tomatoes' characteristic color, flavor and texture, and could give plant biologists a wealth of new genetic information to manipulate, either through breeding or otherwise. Tomatoes represent a $2 billion market in the United States, according to Cornell.

"Tomato genetics underlies the potential for improved taste every home gardener knows and every supermarket shopper desires," says James Giovannoni, a scientist at the Boyce Thompson Institute for Plant Research, located on the campus of Cornell University, who led the U.S. sequencing team. "The genome sequence will help solve this and many other issues in tomato production and quality."

Just last week, plant biotechnologists cracked the code of tomato taste, using statistical analysis of taste tests to isolate two dozen flavor compounds controlling sweetness and intensity. "We now know exactly what we need to do to fix the broken tomato," said Harry Klee of the University of Florida.

Today, that's truer than ever. The two tomato gene sequences suggest there's not much difference between delicious, sumptuously sweet garden varieties and the sandy-fleshed red blobs found at the supermarket. The varieties have just 0.6% nucleotide divergence, or 5.4 million single nucleotide polymorphisms, differentiating them - so breeding desirable qualities back into domesticated cultivars may not require many revisions.

As an example, around 50 genes are involved in the construction of tomato cell walls during fruit development, a trait which has a major impact on the fruit's texture. The several million SNPs could have boundless potential, serving as a new reservoir of tomato traits.

Beyond just improving the tomato, the new genome sequences provide scientists with a new system for studying its closest relatives in the night-shade family. So many of our food crops are direct tomato relatives, including the potato, pepper, petunia, tobacco and even coffee. The Tomato Consortium obtained some data from the Potato Genome Sequencing Consortium and compared the two plants, which are genetically only 8 percent different. And other fleshy fruits could benefit, too - melons, apples, strawberries and many more share characteristics with tomatoes. A tomato gene framework will allow for easier comparison of common and divergent plant gene sequences.

It will also be much easier for other scientists - and seed companies and plant breeders - to sequence different tomato varietals, by building on this genome scaffold.

"Now we can start asking a lot more interesting questions about fruit biology, disease resistance, root development and nutritional qualities," Giovannoni said in a statement.

The paper appears in the May 31 edition of Nature.

Quadrotor The transformed quadrotor uses a magnetic field to remotely charge receivers. NIMBUS Lab

Even though we've been able to keep in touch for long stretches of time since the advent of cellphones, there's still heaps of trouble with keeping them alive long enough to be any good. But wireless everywhere is the way of the future, and roboticists from the NIMBUS Lab at the University of Nebraska-Lincoln have a very futuristic solution: a flying, wireless quadrotor inductive charger.

It works like this: Two coils go on; one for the quadrotor and one for whatever you need charged. The quadrotor drives a current, which forms an oscillating magnetic field. The quadrotor can hover nearby enough to cause the receiver's coil to resonate with the field, which induces a voltage the charging object can use. If it can keep close enough to the object, the quadrotor can send 5.5 watts of power with 35 percent efficiency - enough to power a lightbulb and still have some charge left over as change.

Not that the engineers only have lightbulbs or cellphones in mind for the project: An underwater robot sent down for data could return and recharge with help from the quadrotor, or an outdoor sensor could get electronic aid when there aren't options for solar or grid power.

Nike+ Training System Sam Kaplan

Personal fitness monitors are great at collecting data but fail at providing useful interpretations. Users often have no way to translate speed, distance and calories into metrics that can help guide them to improve over time. The Nike+ Training system is the only monitor that records data, processes it, and delivers real-time coaching.

The system comprises a pair of sneakers with Bluetooth-enabled sensors and an iPhone app with preprogrammed workouts. During a training session, the app issues motivating cues ("Move faster!" "Jump higher!") to the user. After the session, the app breaks down the user's stats to help him spot weak points.

The Sneaker: Designers made the midsole of the Lunar TR1+ trainers from Nike's own lightweight shock-absorbent foam. They also reinforced the mesh upper with rigid Kevlar threads to make the shoe more supportive.

Pressure Sensors: A printed circuit with four pressure sensors sits on the midsole and underneath the removable sock liner. The sensors correspond to the user's big toe, ball, outstep and heel and gather data on every step.

Sports Sensor: The Sports Sensor adds distance and speed data from its onboard accelerometer to data from the pressure sensors and sends it over Bluetooth 4.0 to the Nike+ app. Users can remove the Sensor to charge the system via USB.

Nike+ App: To analyze workout results, the app uses algorithms that recognize movements. For instance, it could combine readings from the toe and accelerometer to calculate the height of a jump. At the end of a workout, the user can look over stats drill by drill and compare them with past results. If he took few steps in a shuffle drill, for example, he might focus on exercises to boost speed next time.

Chemical Circuit A chemical chip can deliver a neurotransmitter like acetylcholine, which enables chemical control of muscles. Linköping University, Sweden

The human body isn't a metal machine, but it's still plenty complicated, and regulating it like a machine is tough to pull off. That's why a new discovery by Klas Tybrandt, a doctoral student in Organic Electronics at Linköping University, Sweden, is exciting: he's developed the first integrated chemical chip, similar to silicon-based electronics, but for biologic material.

A chemical circuit made from it lets chemical substances-different types with different purposes-travel through the body, but still keeps them under control. Send a certain chemical to muscle synapses that aren't signaling, for example, and guide it via the circuit. (The big chemical contender in this seems to be the neurotransmitter acetylcholine, which enables control of muscles.) Before this, the Organic Electronics research group at Linköping University had already developed transistors for transporting molecules, but this circuit offers a lot more flexibility-what was once delivery to single cells is now entire pathways.

Researchers are hoping this opens the gate for a whole new field of circuit technology based on ions and molecules instead of electrons and holes.

Guess What's Cooking in the Garage

The next big breakthrough in synthetic biology just might come from an amateur scientist

What follows is a modified excerpt from Bunch of Amateurs: A Search for the American Character, out now.

On Fillmore Street in San Francisco, in that stretch that's still mostly boho coffee joints with a head shop and an art gallery or two, I met Meredith Patterson. She didn't exactly stand out among the denizens of the Lower Haight. In her 30s and pushing 5ʼ10ʼʼ in her combat boots, she had on a tough-looking leather jacket and cat's-eye glasses that finished off her look with a nice hint of 1950s girl nerd. Patterson is classic self-invented obsessive. A computer programmer and language theorist by day, she's somebody who's loved anything do-it-yourself since she was a little girl, working beside her dad fixing the family car or rewiring the house. Not long ago, she found herself in the grip of a new enthusiasm: homebrew bioengineering.

America has always been a place of ambitious amateurs. And the latest in the long line of them are self-taught biologists like Patterson. These synthetic biologists, so called because they try to engineer new forms of life, are trying to do for the chromosome what Steve Jobs did for the computer. In the bigger cities, they have started to form "synbio" clubs, the same way radio enthusiasts did in the early 1900s or computer programmers did in the 1970s or robotics amateurs did in the '00s. A few of those clubs have even opened brick-and-mortar labs where members can practice tweaking various genomes as a group.

Ask most people about the amateur spirit, and they'll say, well, that was then. It's almost common wisdom that the golden age of the self-invented upstart ended sometime about a generation ago. But the fact is, we've been hearing this line for at least a century, and it's always wrong. The time of outsiders and amateurs and cranks is not a bygone era, but rather a cycle that comes around just when you think it's over. This cycle is an essential part of America's history-arguably the country's genesis story.

Ever since Ben Franklin left Boston for Philadelphia, and continuing right up through when Mark Zuckerberg abandoned Harvard Square for Palo Alto, there has been this sense that a certain kind of creativity happens on the fly, often on the lam, after beginning in one of those proving grounds of American ingenuity: the dorm room, the weekend hobby club, the garage. For Patterson, that proving ground happens to be a tabletop lab situated in the breakfast nook just outside the kitchen of her apartment. She had invited me out to check out her rig-a collection of mostly repurposed and (fairly) common household devices that she uses to fiddle around with the building blocks of life-and to help her with the next step of her latest project. She wanted to insert a plasmid of jellyfish DNA into a bacterium so that later she might cultivate a modified form of yogurt, one that tasted great but also glowed in the dark.

* * *

Before we got to any serious bioengineering, Patterson said we'd have to visit one of her go-to synbio supply stores: Trader Joe's, which sold plain yogurt containing the bacteria we'd need, Lactobacillus acidophilus. During our walk, I noticed a tattoo on her ankle. She pulled her pants up above her boot. "This one's not done yet," she said. It was a steampunk biomechanical x-ray of her lower tibia and fibula, a series of mechanical cogs, robotic pistons and bicycle chains. "It's kind of a joke, because I have these weird mutant ankles," she explained. "I have this thing called an accessory navicular bone." Patterson has a number of tattoos, all of which relate in some way to her sense of herself as an off-the-grid scientist. On one arm she has a rose window and sword from her favorite anime serial, "Revolutionary Girl Utena." Down the bicep is the iconic image of Atlas holding up the heavens, most familiar as the paperback cover art of Ayn Rand's novel Atlas Shrugged. And keeping the burdened Titan company is the Page of Pentacles, the tarot-card figure who, she says, signifies the "eternal student."

The crucial ingredient for Patterson's "Glo-gurt" is a gene known as green fluorescent protein, or GFP. Originally found in jellyfish and a species of polyp called the sea pansy, GFP allows these creatures to bioluminesce when disturbed. In 2000, an artist named Eduardo Kac created "GFP Bunny," a genetically altered albino hare that glowed bright green in the presence of ultraviolet light. Since then, the gene and its colorful relatives have been domesticated-very domesticated. Pet stores now sell GFP-altered zebra fish as GloFish ($7.99 a piece, $6.99 if you buy three-now available in Starfire Red, Electric Green, Sunburst Orange, Cosmic Blue and Galactic Purple). Three scientists who studied the gene won a Nobel Prize in 2008, and GFP is more seriously used as a marker to track all kinds of changes and effects at the genetic level. Patterson's aim with Glo-gurt is not quite so high. She thought it would be cool, she told me, to go to a rave with glow sticks she could eat.

When we arrived back at her apartment, Patterson showed me a sample of the glow-in-the-dark plasmid that she had obtained; she kept it sealed in a bag in her freezer next to some frozen chicken wings and a box of Eggos. She had ordered it from the Carolina Biological Supply Company in North Carolina the same way someone else might order a sweater. Her basic plan was to grow a batch of the yogurt bacteria, introduce the GFP gene into the cells, and then use that modified bacteria to make yogurt again. To do so, we would need to improvise an electroporation device that could help usher the glow-in-the-dark gene into the Lactobacillus.

Electroporation is a common genetic procedure that involves exposing cells to a 2,500-volt, pulsed electrical field. In bacteria, the charge changes the permeability of the cell membrane, making it possible to pass the GFP plasmid through it. "Essentially," Patterson said, "we're going to taser them."

Synthetic biologists hope to do for the chromosome what Steve Jobs did for the computer.Patterson does all of her work, high-voltage and otherwise, in her apartment, a place shared by a changing cast of roommates. It's all very familiar-a friendly wreck of used furniture, piles of books and boxes, coats, beanbag chairs, and a potted glade of houseplants clustered desperately at the windows. Scattered on the table that serves as her lab is her improvised genetic gear. Patterson long ago solved the problem of obtaining lab-quality pipettes (because they can run around $200) by purchasing, from an online pharmacy, cheap disposable insulin needles that can measure down to the microliter. She reengineered a nine-inch floppy-drive motor from a computer she bought used for $5 to serve as a centrifuge for spinning vials of liquid containing bacteria. Her autoclave is a pressure cooker, and her incubator is a tailgater's fridge from Sharper Image that can cool or warm. "Someone was getting rid of one of these for $30," she said. "Mine now."

There's a playful quality to all this. Whether it's bale-wiring some junk she bought at a street sale or working out ingenious substitutes from the local pharmacy, Patterson talks about creating her lab with as much glee as she does the genetic engineering she's attempting. And that same joy, call it subversive freedom, is what drew her into synbio in the first place. When the programmers conference CodeCon was being scheduled a few years ago, she volunteered to put on a little DNA show, and the organizers agreed. She wanted to illuminate the seemingly complex world that most of us imagine when we hear words like "recombinant DNA" and show that it was quite accessible. For instance, the process of extracting DNA from the classic green pea, the subject of Gregor Mendel's famous experiments, can be made to sound very complicated. A professional in a lab might discuss cell disruption to penetrate the membrane, followed by removal of lipids, followed by an isopropanol bath and a protease wash, followed by some turns in a centrifuge to yield a bit of stringy DNA in the bottom of a test tube. But Patterson showed up to the conference with a box of stuff found in most kitchens or bathrooms./>

"I started with dried ground-up peas," she said, "and I put those in a saline buffer." She quickly translates for me: "regular old saltwater." Then, she continued, "you shake it up a little bit and add some shampoo, which contains a detergent, which breaks apart the fatty cell wall. To that you add meat tenderizer, which contains papain, which is a protease that breaks down the nucleus." So the shampoo gets us inside the cell, and the meat tenderizer gets us inside the nucleus where the DNA resides and releases it from the proteins that accompany it. Then you let it sit for a while until it turns into what Patterson calls a "slurry" of "digested goo." This gunk is put into a salad spinner to separate the solids from the liquids. After pouring off the liquid, you add rubbing alcohol. DNA likes alcohol about as much as oil likes water, so it tends to bunch together to separate itself from the rest of the liquid. Sticky strings begin to form. This is pure, extracted DNA, ready for bioengineering.

* * *

Part of the freedom and pleasure that amateurs feel while doing their research derives from the fact that their workspaces usually contain no black boxes. Among Patterson's lab equipment, there's nothing store-bought whose processes she doesn't understand. She's built and rebuilt everything. When I asked, for instance, about the broth in the tubes-that is, the food that would feed our bacteria as they grew overnight-she said, "Normally when you are growing lacto, you use MRS broth. MRS stands for a couple of guys [three scientists: J.D. DeMan, M. Rogosa and M.E. Sharpe]. But that stuff is expensive," so she made her own. "What I did was manage to track down an article Paul Elliker wrote in the Journal of Dairy Science." The article was written in 1956. Talk about going back to basics. "I could have solved the problem by throwing money at it," she said, "but what I've generally found is that old articles tend to have the cheapest but still effective way of going about anything."

This kind of improvisational approach to research and experimentation lends a certain levity of purpose to any amateur endeavor. When things went perfectly, Patterson's work gave way to moments of intense and obscure beauty. To add distilled water to our vials of bacteria, she cleaned her hands and carefully removed a single sterilized corked tube. With one elegant motion, she drew up some water with a syringe; with the other she one-handedly popped the cork. She looked sideways at the open tube so that her slight breathing wouldn't contaminate her work. Then she pipetted just enough in, recorking the tube once the process was finished. Twenty times, perfectly, like a tiny private ballet.

In less-than-perfect moments, when something went wrong, Patterson just stepped back, thought about things for a while, and dove back in. She doesn't get frustrated easily, a trait she ascribes to her parents' constant encouragement when she was a kid. But it's also the case that amateurs simply have a different relationship to frustration, and even failure. At an office, failure and success are binary modes, down and up (and often linked directly to pay). Public failure, too, can be discouraging and embarrassing. In the worst cases, it can get you marginalized or fired.

But if the entire rig on your kitchen table is your creation, hatched from street cast-offs and dairy farmers' lessons dating from the Eisenhower administration, then failure is just a glitch in the system you've built. Putting one's hands in there, e-mailing other kindred scientists for advice, checking out colleagues on a common wiki, fixing what's wrong, and moving one's investigations forward are simply short-term variations of success.

On one of the many long nights that Patterson and I would spend together piecing together her system, we had a brief discussion of flow, the notion developed by Mihaly Csikszentmihalyi (pronounced "me-high chick-sent-me-high"-perhaps the most fun name to say, ever). This Hungarian-American psychologist holds that there is a very satisfying state of mind that occurs when one is totally absorbed by an action. It may sound as if this is some rare state of being, like a kind of secular nirvana, but it's not. We all experience flow. It doesn't require special meditative skills, only the love of doing something so much so that one gets lost in the labor. One might experience flow while painting a complex landscape or painting the front porch. Or chaperoning growing bacteria.

Its commonness is why we have so many phrases for this pleasant state of existence: being in the zone, losing ourselves in our work, being on the ball, in the groove. "Oh," Patterson said, suddenly recognizing what I was talking about. "You mean codespace," as programmers call it, "where the world just sort of disappears." She knew it well. "That's a good head space to try new things, especially if there's something I think should work. So I try it and see if it does: ‘That didn't quite work the way it was supposed to. Let's check a few settings and see if this works.' Sweet."

* * *

The word "amateur" comes from the Latin word for "love," which, when encouraged with money, becomes a profession. An amateur's love is typically free of direct pay, such that while money might ultimately be involved, it's not the day-to-day incentive. It's a kind of love that hasn't very well spoken its name. It's neither eros nor agape, nothing involving filial bonding or generous charity. It may, in fact, be the least described love-a peculiar version of self-love, charged with the hope of finding that new thing just over the horizon.

In the months before my visit, Patterson had already been working to coax the glow-in-the-dark gene into her yogurt bacterium. She had tried to use the heat-shock method to drive it into the cells. "When bacteria get to a certain temperature, they start producing these heat-shock proteins, which also open up some holes," she explained. And in that brief moment, the new genes sloshing around nearby can slip in. "In my head, it's like: Holy shit, it's hot in here, let's open some windows."

Patterson's autoclave is a pressure cooker, and her incubator is a tailgater's fridge from Sharper Image.But heat shock hadn't worked, so she had moved on to electroporation. When she first described it to me, I pictured the bacterium ballooning like a cartoon character with its finger in a socket-its flagella sticking out like hair and its microscopic pores bulging open like wide eye sockets-such that the GFP plasmid could rush in. For us, the question was how to administer these shocks to our bacteria. Patterson had configured the timing mechanism on an Arduino, an easily customized computer board. It would handle the literally split-second timing. All we needed now was 2,500 volts (the precise amount, I recently learned, once used to carry out the missions of famous 20th-century electric chairs, the insanely powerful ones with nicknames like Gruesome Gertie, Yellow Mama, Old Smokey and Sizzlin' Sally).

To accomplish this, Patterson got hold of a transformer from an old neon sign. It takes in 12 volts and ramps it up to 3,000 volts, so it would seem to make sense that if we fed the transformer 10 volts, it would kick out 2,500. But Patterson's voltmeter kept telling us something was slightly off here. We tried different connections and different transistors, and then we needed another part, and then there was a road trip to Fry's, a kind of Home Depot for everything electronic, and then, was that the sun setting already?

We must have tested the input and outputs of the Arduino board 50 times. These tests amounted to us sitting on the wooden floor and carefully holding the (insulated) lines in place as we blasted away with potentially lethal streams of electricity. One day we spent 10 hours trying to configure one wiring setup after another. Hours of this fiddling passed, but it was as if no time had passed at all.

Meanwhile, the tiny amount of yogurt Lactobacillus we had placed in the incubator was growing away. But there was a flaw in that system, too. The incubator's two-bit thermostat had busted. There was no longer a way to automatically regulate the heat inside, so Patterson would carefully monitor the temperature herself. She would turn the incubator off after a while and wait for it to cool down a few degrees before turning it back on. This way, she kept it from overcooking our bugs. We were now several days into constant experimentation, and we spent a lot of time together, staring at transistors, tending the incubator as if it were an old wood stove, sterilizing equipment, waiting for very slow things to happen. Patterson is a smoker, and in moments precisely like these, I allow myself a temporary relapse into a habit I enjoyed ages ago. So we'd take cigarette breaks, standing by her window.

Well into one evening, as we sat in our own groove, occupied by long stretches of work, suddenly there appeared a solution to the thermostat problem, like a bubble slowly popping at the surface of our flow. "What about one of those light timers you can get to fool burglars?" I asked. Patterson instantly got it. Yes. A light timer. We could program it to turn the incubator off and on. Then we could leave the apartment building for more than an hour. We raced downstairs and drove south to a late-night Home Depot in San Jose. The new models were perfect for what we were doing, and only a few bucks. Controls allowed you to customize the on/off cycle however you wanted-on for five minutes, off for 30, for instance.

Problem solved. By the time we got the timer set up, dawn was on the way. We would eventually have to return to our transistor flow, but for now, there was this intense pleasure. We both stepped back, looking at a light timer plugged into a surge protector with, absurdly, an exhilarating amount of self-satisfaction. Time to light up.

Patterson and homebrew biologists like her may form the body of a nascent synbio movement, but the architects of that movement still come almost entirely from academe. The most visible booster of synthetic biology is probably Drew Endy, a professor of bioengineering at Stanford University. Young-looking, with slightly mussed sandy hair, Endy could easily be mistaken for a perpetual grad student. He coins hackerish jargon that sounds super-hip. If you listen carefully on the Stanford campus, maybe you'll hear someone referring to the shifting of a gene from one life-form to another as "DNA bashing."/>

Endy predicts a time (soon) when someone will rewrite the DNA of an acorn to include George Jetson-like instructions that direct the future oak to assemble into a bookshelf. He also says that the leading synthetic biologists need to aid and abet amateurs like Patterson if this emerging science is going to rapidly advance. In 2003, he helped found iGem, the International Genetic Engineered Machine competition. Held at the Massachusetts Institute of Technology every year, iGem invites teams of college and high-school students and amateurs from all over the world to strut their bioengineering stuff and compete for a Lego-shaped BioBrick Trophy that comes complete with its own suitcase.

Endy is also working to standardize the parts that synbio researchers use, which could help to jump-start the amateur cycle. He loves to tell the story of William Sellers, an engineer who wrote an important paper around the time the Civil War was winding up. Sellers suggested that American engineers adopt a standard for all nuts and bolts. He proposed a formula that would create a standard pitch of screw thread conformed to the bolt's diameter. In case you're interested:

P = 0.24 √D + 0.625 - 0.175

Today Americans still screw, more or less, thanks to the Sellers system. The key feature of standardization, Endy says, was that every Sellers nut, when screwed into a Sellers bolt, behaved the same way. "When you pull on the nut," Endy says, "it stays put. It doesn't come flying off the bolt." In other words, it does what it is supposed to do, a feature that Endy and other engineers call "reliable, functional composition."

Endy predicts a time when someone will rewrite the DNA of an acorn to direct the future oak to assemble into a bookshelf.This reliability is one of those structural changes to early American manufacturing that drove its rapid progress in the 19th century. Endy thinks a similar reliability is possible for DNA research. For instance, MIT maintains a Registry of Standard Biological Parts, a one-stop shop for DNA standards. Geneticists anywhere can order various plasmids or other strings of DNA known to cause a catalog's worth of biological features. And it works the other way, too. You can register a new DNA strand with a novel functionality-for example, a "biosynthetic device" that changes the nasty manure-like odor of growing lab bacteria into the pleasant aroma of a banana. This bio-widget, or "banana odor biosynthetic system," has been standardized and registered, available in the catalog as part BBa_J45900. The idea is that the registry will become a kind of RadioShack for DNA parts, so that DIY folks and academics alike will start playing and creating, advancing the science quickly. The number of standard biological parts doubles every year, and, Endy has said, "the same thing is happening with the number of teenagers who would like to do genetic engineering; it's doubling every year." Five teams competed at iGem in 2004; 165 competed last year.

If you listen to Endy-with his talk of iGem and the parts-registry and his "gene bashing" lingo-you'd begin to think he could single-handedly guide synbio into the mainstream. But he is just one of a kind of secular trinity of academic leaders birthing this new field. The others are Jay Keasling of the University of California at Berkeley and George Church of Harvard University.

A biochemical engineer, Keasling does not talk about making synbio cool or bashing genes. Instead he focuses on making synthetic biology do very specific things. For instance, he'd like to cure malaria. The treatment for that disease involves a substance called artemisinin, which derives from the slow-growing sweet wormwood plant. Keasling developed a bacteria that quickly pumps out artemisinin, and in 2010, he announced that he was beginning production of the drug. If all goes well, he'll commercialize it this year.

Perhaps the most practical of the synbio leaders is George Church. He is a towering 6ʼ5ʼʼ, with a lumberjack's beard, a commanding presence, and a seductively hyperactive and chatty mind, not to mention a brilliant scientific eccentricity: He suffers from narcolepsy. So the great man can be speaking to you and, boom, he blinks out for five seconds and then boots right back up. It's the equivalent of Einstein's hair, notice given that you are in the presence of wild and ranging genius.

As Patterson and her peers start testing out their new ideas, a public debate will eventually arise: Just what are we permitting here?Church talks up synbio's economic potential, specifically fuels. He wants to engineer something that makes a lot of money and gets positive attention. The obstacle to turning piles of organic material such as switchgrass into easy biofuels is that the sugars in the plant are bound up by cellulose. To get it out, the cellulose has to be extracted. What if you could design a bacterium that transforms cellulose into usable sugars? That would have a worldwide market almost immediately. "Biofuels are the low-hanging fruit of synthetic biology," Church told me in his office one afternoon. Pharmaceutical cures might earn good press, but the demand for them is small relative to the demand for fuels, "where the markets are huge."

Everyone involved in synthetic biology recognizes that if robotics, say, is a weekend amateur pursuit whose clubs are in their mature phase, then synbio is in utero. So they worry constantly about public relations and imagery. They know that some story will break the field into the pop culture-a brilliant discovery, a cool movie, but also, possibly, a tabloid freak-out that calls down Homeland Security.

"NASA had the moon shot," Church said, as he pondered how the public comes to understand the complexities of any new scientific discipline. "There was the homebrew computer club. Even robotics had a cinematic push." He recognizes that Hollywood prefers to deal in a "dystopic version of biology." He considered the ill effects of Jurassic Park, Gattaca or I Am Legend. "There is one isolated nondystopic movie," Church said: Lorenzo's Oil, the story of parents who will stop at nothing to find a cure for their child's rare affliction. The movie was not exactly a hit. "You can see how hard it is for Hollywood to make a blockbuster out of lipid chemistry," he said.

Around midnight in San Francisco, Patterson and I are on the floor with our 40th or 50th attempt at configuring the 2,500-volt transformer. Even here, in this most isolated lab, the synbio community is all around us. Patterson regularly checks old e-mails for advice, downloads one more schematic from another site, consults with a wiki or two. Late in the evening, she calls a guy named Brian who's a whiz at electrical things, and they confer for 20 minutes. "Brian's advice was to turn these around," she says, pointing at two connectors with wires, "and put the load between the power supply and the collector." So we make our adjustments and continue to find problems with the connections. Work like this is mostly just the tedium of getting things right or attempting to, and for long stretches the only sound is Patterson cheerfully muttering to herself:/>

"Something lights up-well, hello."

"That's a 15k resistor. Again, didn't work."

"I'm wondering if I've misunderstood which pin is which. If I did, that would be stupid."

"Things that do not make sense include . . ."

"Where the hell are you coming from?"

"Plug us in."

"Again, we're not getting squat."

We both stare at the tiny board one more time.

"We want red to go here and black to go here, and somebody needs to touch this wire to the base. So if you want to just hold these, I can plug it in. First, make sure you are not touching the lead. Good."

A vicious snapping sound shatters the concentrated silence of the room. Some lights go out, throughout the building. Patterson pulls the plug. "Time for a cigarette break," she says.

With electroporation out, Patterson explains, we'll have to resort to the next best way to get a plasmid into a bacterium: an ultrasound bath. This involves the same technology that allows us to peer inside a womb and look at a fetus. "Ultrasound is used in labs normally for lysing cells, for ripping them open and getting out the DNA," she explains. "And it is also used for sterilization. A really high amplitude of ultrasound can be used to kill off bacteria. When the frequency is in the 40-kilohertz range, you can actually use it for transsection, one of the terms for introducing plasmids into things." (Having failed at frying the bacteria and then shocking them, we now hoped to yell at them.) The question is, how do you get an ultrasound machine? "This thing ran 40 bucks," she says-this thing being a "jewelry cleaner operating at 40 kilohertz." The machine is small and compact, easy to handle. Dozens of them are offered for sale on eBay on any given day.

Even as she presses forward in search of Glo-gurt, though, Patterson tells me her interests have recently shifted to something more functional. She's started a conversation with an Internet pal on the DIYbio listserve about synthesizing a bacterium that would react in the presence of melamine. Recall that in 2008, this substance began showing up in Chinese imports of milk products, eggs, baby food and pet food and led to numerous deaths of people and animals. Melamine-contaminated milk alone sickened some 50,000 people. The reports caused a food scare and focused attention on the fact that American agencies were not testing for the presence of these lethal chemicals. Patterson and her online research partner call their creation the Melaminometer.

One approach they are considering is to create bacteria that, in the presence of melamine, would break down the substance into ammonia and water. Not all that tasty, but it beats getting sick. Maybe they can make the chemical taste like bananas when they get around to Melaminometer 2.0. Like so many amateurs, Patterson sees in the possibilities of all these plasmids what William Sellers saw in a dependable, well-threaded screw-a better future.

As Patterson and her peers start trying out their ideas and experiments, a public debate will eventually arise: Just what are we permitting here? And the usual anxieties will erupt. Are we unleashing a generation of Dr. Frankensteins? How soon before we hear about the possibility of weaponized flu in some kid's suburban den? All the more reason, the DIY supporters say, to encourage the local synbio clubs. Members are struggling right now to define the appropriate standards, general ethics and good lab protocol. Of course, if history is any teacher, then an ambitious prosecutor might well swoop into these clubs. On the other hand, if Endy, Keasling and Church can stage-manage synbio's image well enough, the clubs could flourish and foster novel approaches to genomics. There are always natural concerns when any new set of tools is handed to the next generation. But the way this anxiety gets addressed-as the next 4H club or as the next national security threat-will reveal a lot about how we currently view American innovation.

The elder statesman of theoretical physics and a big synbio fan, Freeman Dyson, wrote an influential essay in the New York Review of Books in 2007 in which he called for precisely the kind of synthetic biology research we are now beginning to see. "Every orchid or rose or lizard or snake is the work of a dedicated and skilled breeder," Dyson wrote. "There are thousands of people, amateurs and professionals, who devote their lives to this business. Now imagine what will happen when the tools of genetic engineering become accessible to these people.

"There will be do-it-yourself kits for gardeners," Dyson continued, "who will use genetic engineering to breed new varieties of roses and orchids. Also kits for lovers of pigeons and parrots and lizards and snakes to breed new varieties of pets. Breeders of dogs and cats will have their kits too. Domesticated biotechnology, once it gets into the hands of housewives and children, will give us an explosion of diversity of new living creatures, rather than the monoculture crops that the big corporations prefer. New lineages will proliferate to replace those that monoculture farming and deforestation have destroyed. Designing genomes will be a personal thing, a new art form as creative as painting or sculpture."

It's not a brave new world that Dyson envisions, but rather the same old mundane one, just gussied up with the middlebrow creations of housewives and teens. And the exquisite dreams of a Meredith Patterson. Maybe that is where we're headed, but make no mistake about how we will get there. Dyson and his co-enthusiasts want to put the toolbox for life itself into the hands of an amateur designer. Presumably, an intelligent one.

Dragon Capsule SpaceX

Updated: One last major milestone achieved for SpaceX's Dragon capsule today: A successful splashdown and recovery. The privately built spacecraft unlatched from the International Space Station earlier this morning and returned to Earth, parachuting to an ocean landing.

Dragon careened back to the surface "like a burning comet," according to NASA, albeit a controlled one. Thrusters on its exterior guide it to the proper landing spot, which was about 490 nautical miles southwest of Los Angeles.

"Dragon is in the water," said Josh Byerly of NASA's Johnson Space Center in Houston, according to wire reports.

Reminiscent of the Apollo and Mercury splashdown days, three ships served as recovery boats, according to the AFP. Only this time, it wasn't the U.S. Navy who retrieved them.

Dragon is carrying cargo from the ISS, so its next destination is Texas, so the cargo can be returned to NASA.

This will be a real feat, because other cargo ships never return home after docking with the ISS. Dragon is different because it can be used again and again, for cargo or eventually crew. Dragon connected with the ISS over the weekend after a successful launch May 22.

Centaurus A's Clouds of Gas This new image of Centaurus A combines ALMA and near-infrared observations of the massive elliptical radio galaxy. The new ALMA observations, shown in a range of green, yellow and orange colors, reveal the position and motion of the clouds of gas in the galaxy. They are the sharpest and most sensitive such observations ever made. ALMA (ESO/NAOJ/NRAO); ESO/Y. Beletsky

Along with hosting a supermassive black hole at its heart, the center of the radio-loud galaxy Centaurus A is home to a stellar nursery that tells a tale of the galaxy's past. The presence of a dark band of dust, as well as the galaxy's powerful emissions in the radio end of the spectrum, suggest it formed in a collision between a giant elliptical galaxy and a smaller spiral galaxy.

But that dark dust band blocks out the galaxy's bright center, and to see past it, astronomers have to look in longer wavelengths of light. Today's pretty space pic reveals the position and motion of the gas clouds at Centaurus A's center, the sharpest and most sensitive images ever made. The colors are the result of the Doppler effect as the gas clouds swirl around.

ALMA can detect signatures with a wavelength around 1.3 millimeters, which corresponds to carbon monoxide. As the gas moves around, it causes changes to this wavelength as seen from here. Greener features correspond to gas coming toward us, while orange areas represent gas moving away. So the gas is obviously swirling around the galactic center in this image.

This image is a combination of ALMA observations and near-infrared observations from the European Southern Observatory's New Technology Telescope. The Atacama Large Millimeter/sub-millimeter Array is set to be completed last year, but already observations with a partial array are yielding beautiful and bountiful results.

Finnish Scientists Announce a Possible Universal Allergy Vaccine

Scientists at the University of Eastern Finland say they hope to have an allergy vaccine on the market in five to seven years.

For everything, from pollen to cat hair.

The antibody immunoglobulin E (IgE) works as the sneezy gatekeeper for allergies: it causes your white blood cells to release histamine, which in turn causes all of your favorite allergic responses, from a watery eyes to hay fever. Now, a team of scientists led by Professor Juhu Rouvinen have found a means of genetically modifying allergens so they won't bind with IgE, while still allowing them to interact with immunoglobulin G. IgG is the friendly cousin of IgE; it keeps allergies out by stopping the IgE-allergen complex from forming. That could block histamine from coming out of white blood cells, and thus block that runny nose. After that, it's simple, at least in theory: Just load a modified version in a shot and let the immune system take care of the rest.

Five to seven years might be a few too many springs away for allergy sufferers, but the team has formed a bio-tech company, Desentum, to help in production.

When he's not busy with his full-time gig, NASA Astronaut Don Pettit takes the time to run some of his own personal science experiments. His latest? A zero-gravity didgeridoo performance - for science.

Actually, it's not really a didgeridoo: Pettit takes a space station vacuum cleaner and cleaves off half of it, attaching two different end pieces and measuring their resonance against a couple drops of water, which throb excitingly and shed mini-droplets. Even if you're not interested in tribal music or liquid surface tension in space, the video is worth watching if only for the wacky costume change.

Video: After Robot-Assisted Rehab and a Dose of Chemicals, Paralyzed Rats Walk Again

Walking Again After neurorehabilitation with a combination of a robotic harness and electrical-chemical stimulation, a paralyzed rat takes its first steps up the stairs. EPFL/Grégoire Courtine

With careful training using a robotic harness, and a special chemical cocktail designed to stimulate brain cells, rats with spinal cord injuries were able to re-learn how to walk. Scientists in Switzerland say the tests suggest humans with paralysis due to spinal cord injuries may regain some nerve activity.

The therapy takes advantage of the nervous system's inherent plasticity, in which neural networks can be rewired to take on different tasks. Areas of the motor cortex were able to establish new connections to the rats' hind limbs, which had been paralyzed due to spinal cord injuries in a manner similar to spinal cord paralysis in people.

Despite the nervous system's ability to reroute itself, half of human spinal cord injuries lead to paralysis, according to researchers led by Grégoire Courtine at the Swiss Federal Institute of Technology. But with a neural prosthesis, in this case an electrochemical treatment, and a robotic assistance device, even the most debilitating injury can be re-routed. The trick was rousing the dormant spinal column, the researchers say.

This is different from other robotically mediated paralysis therapy we saw recently involving brain-derived motor control. In that study, human patients wore a cranial device that tapped into their thoughts to control a robotic arm. In this case, the treatment is physiological, inducing dormant neurons to forge new connections and move limbs directly.

First, Courtine and colleagues injected the rats with a chemical cocktail that binds to dopamine, adrenaline and serotonin receptors on the spinal cord's neurons. This replaced the neurotransmitters that would normally be released in healthy spinal pathways. A few minutes after priming the neurons, the team stimulated the rats' spinal cords through electrodes implanted into the spinal canal. This sent electrical signals to the roused neurons. Then the rats needed to be trained to use their limbs again. Within a week of their injuries, the rats were on treadmills, forging new neural connections.


Courtine and colleagues built a little rat vest that supported the animals as they stood on the treadmill. The vest stood them up on their hind legs, basically forcing them to use their paralyzed hind legs to walk upright. The rats tried to move toward a piece of chocolate on the other end, and gradually this "willpower-based training" built up new nerve fibers, the researchers say.

After two weeks of training, the rats took their first voluntary steps on their paralyzed legs. Within five or six weeks, all the rats in the study were able to walk bipedally, on their hind legs, for extended periods, Courtine et al. say.

"This is the world-cup of neurorehabilitation," Courtine said in an EPFL news release. "Our rats have become athletes when just weeks before they were completely paralyzed. I am talking about 100 percent recuperation of voluntary movement."

This is still a long way from working in humans, however. But human clinical trials are already on the horizon, set to start within two years in Zurich, according to EPFL.


The paper will be published in this week's issue of Science.

Meet Gibbot

Robot locomotion can take many forms, from crawling like snakes to rolling like tanks. This one swings like an android ape, using brachiating arm motion to grab onto a surface and forward momentum to keep going.

"Gibbot" is being developed at Northwestern University, where researchers are studying robot horizontal movement, according to IEEE Spectrum. It mimics the brachiating movement of gibbons, which swing through trees with ease. Like gibbons, it's designed to keep moving by conserving energy - a fast grab-and-go ensures forward momentum is not lost.

It contains two electromagnets at the ends of both arms, which grab onto a steel wall in the demonstration below. Finding the right gait and grabby motion is a key challenge, but with the right movements, the researchers say it's theoretically possible to brachiate forever. The Northwestern team, led by Kevin M. Lynch, presented Gibbot at the e 2012 IEEE International Conference on Robotics and Automation this month.

No galaxies were harmed in the creation of this simulation

First, the bad news: In four billion years it's going to get a lot more crowded around here. The Milky Way and Andromeda galaxies are on a collision course. The good news is that a new video from NASA shows how it'll go down.

It's been suggested for some time that the two galaxies might have it in for each other, but today NASA says they can "predict with certainty" that Andromeda, which is still 2.5 million light years away but heading toward us at 250,000 miles per hour, will collide with the Milky Way because of the mutual pull of their gravity.


The two galaxies have enough space between them that any direct collision of heavenly bodies is unlikely. But the Sun won't be getting off so easy; it'll probably be flung into another part of the galaxy.

How 4K Resolution Will Bring Movie-Theater Quality Into the Living Room

The Bigger Picture Quick stats: A DVD has about 345,600 pixels per frame. Blu-ray? 2.1 million. 4K? A whopping 8.8 million. Alison Seiffer

Since the first high-definition televisions came out in 1998, consumers have heard the same tired sales pitch: "It's like having a movie theater in your living room!" Actually, no. An HD image does have nearly the same resolution as one projected in a theater. But when viewed on a large screen in a tight living room, the image's quality degrades markedly. 4K, a resolution standard just beginning to reach consumer markets, promises to make possible the dream of any serious film fan-vast, perfectly crisp movies at home.

A 4K image has at least four pixels for every one in an HD image, allowing for video that's 4,096 pixels wide versus only 1,920 pixels wide in HD. With more and smaller pixels, images will retain their quality both at large screen sizes and at close distances. For example, in the average living room, viewers sit as close as six feet from the screen. At that distance, a 100-inch 4K image will appear sharp and vibrant. At the same distance, a 100-inch HD image will appear grainy and pixelated.

The transition to 4K has already begun. In 2008, IFC Films debuted the first widely released full-length 4K film, Che, directed by Steven Soderbergh. Since then, Sony Pictures has released a handful of 4K movies, including The Green Hornet and Moneyball, and Warner Bros., 20th Century Fox and Paramount have also begun transitioning to dedicated 4K shooting. Meanwhile, the first consumer-grade 4K displays are just starting to come out. Sony and JVC introduced the first 4K home-theater projectors last September. LG says it will launch a 4K flat-panel LCD by next year, and Toshiba is likely to follow suit.

Just as with the transition to HD, mass adoption of 4K will be slow. Film companies must find easy and affordable ways to distribute it. In the short term, that will mean developing new file-compression standards. Next January, the Joint Collaborative Team on Video Coding will finalize a standard known as High Efficiency Video Coding. HEVC will compress files twice as efficiently as the current standard, MPEG-4 AVC, and will allow studios to fit a full-length 4K feature film onto existing media formats, such as Blu-ray discs.

Over the longer term, Internet service providers will need to improve their infrastructure to support 4K streaming. Today, broadband is fast and reliable enough-the average speed in the U.S. is now more than six megabits per second, and fiber connections can be even faster-for Netflix to deliver full-HD movies. Analysts estimate that 4K streaming will demand more than three times current speeds, at least 20 megabits per second on average. But that level of service is coming. South Korea already has a working one-gigabit-per-second fiber-optic network, and Google is currently testing a similar network in Kansas City. When that happens, viewers will not only have brilliant theater-quality screens; they'll have an entire, instant 4K library to go with them.

Researchers Test Space Equipment For Five Days in Austrian Alps

Space in the Alps Researchers used the Austrian Alps as a model for Mars. OEWF (Katja Zanella-Kux)

In the ongoing hunt for Martian life, there's one place astronauts haven't yet explored deeply: caves. But to delve into Martian caves calls for some heavy-duty gear, and where do you test Martian caving gear on Earth? The Austrian Alps.


See our gallery of the most space-like environments on Earth.

A team of volunteers spent five days at the end of April test-driving spacesuits and planetary rovers inside the ice caves of the awesomely/terrifyingly named Eisriesenwelt - German for "World of the Ice Giants." On Mars, explorers might run up against limestone caves or ice caverns, and Eisriesenwelt, a series of labyrinthian caves in central Austria cold enough to freeze all water inside, has both. The Martian incarnations are cold but temperatures are stable, there's less humidity than on the surface of the Red Planet, and they provide shelter against radiation from space - the ideal recipe for sustaining life.

Researchers from the Austrian Space Forum, NASA's Jet Propulsion Laboratory, and 11 other countries on three continents ran a series of tests 4,265 feet above sea level to see just how well the equipment could hold up under strenuous conditions.

For a spacesuit, volunteers donned the 100-pound Aouda.X suit, which insulates the wearer with an aluminum-coated Kevlar-Panox textile. The Aouda.X is packed with enough monitors - for body temperature, heart rate, and carbon dioxide and oxygen levels - to make sure the person inside is always out of harm's way. Researchers also stayed in touch over a radio, directing volunteers toward potential ice and other samples.

Some of the many rovers sent along for testing included a cliff reconnaissance vehicle and a quadrotor drone. At least one lesson was learned: a cliff-climbing bot and a more standard surface-dwelling bot make a good team, and might have some potential as a combined machine one day.

There was a slip-up during testing when one volunteer's headset fell off; researchers opened up the helmet to repair it, which isn't exactly what you want to do while on Mars. That and a few other things offered some lessons. Gernot Grömer, president of the Austrian Space Forum, told Astrobiology Magazine "yes, we can do subsurface exploration, but we need to adjust our way of conducting Mars exploration significantly." When the real deal happens, it'll take astronauts 20 minutes to get a message across to home, and there won't be anyone except other explorers there to help.

The researchers' next test run will be in the northern Sahara in Morocco in February 2013.
