Forgotten Experiment May Explain Origins of Life

Volcano3
Volcano2_2Originally considered a dud, an old volcano-in-a-bottle experiment designed to mimic conditions that may have brewed the components of life might have been right on target.

After reanalyzing the results of unpublished research conducted by Stanley Miller in 1953, chemists realized that his experiment had actually produced a wealth of amino acids — the protein foundation of life.

Miller is famed for the results of experiments on amino acid formation in a jar filled with methane, hydrogen and ammonia — his version of the primordial soup. However, his estimates of atmospheric composition were eventually considered inaccurate. The experiment became regarded as a general rather than useful example of how the first organic molecules may have assembled.

But the latest results, derived from samples found in an old box by one of Miller's former graduate students, come from a device that mimicked volcanic conditions now believed to have existed three billion years ago. The findings suggest that amino acids could have formed when lightning struck pools of gas on the flanks of volcanoes, and are a fitting coda for the late father of prebiotic chemistry.

"What's amazing is that he did it," said study co-author Jeffrey Bada, a Scripps Institute of Oceanography biochemist and Miller's former student. "All I did is have access to his extracts." 

Bada stumbled across the original experiment by accident when a colleague of Miller's mentioned having seen a box of experimental samples in Miller's office. Bada, who inherited Miller's scientific possessions after his death in 2007, found the box — literally labeled "1953-1954 experiments" — in his own office.

Inside it were samples taken by Miller from a device that spewed a concentrated stream of primordial gases over an electrical spark. It was a high-powered variation on the steady-steam apparatus that earned him fame — but unlike that device, it appeared to have produced few amino acids, and was unmentioned in his landmark 1953 Science study, "A Production of Amino Acids Under Possible Primitive Earth Conditions."

But Miller didn't have access to high-performance liquid chromatography, which lets chemists break down and classify samples with once-unthinkable levels of precision. And when Bada's team reanalyzed the disregarded samples, they found no fewer than 22 amino acids, several of which were never seen by Miller in a lifetime of primordial modeling.

Perhaps amino acids first formed when the gases in Miller's device accumulated around active volcanoes, said Bada. "Instead of having global synthesis of organic molecules, you had a lot of little localized factories in the form of these volcanic islands," he said.

"The amino acid precursors formed in a plume and concentrated along tidal shores. They settled in the water, underwent further reactions there, and as they washed along the shore, became concentrated and underwent further polymerization events," explained Indiana University biochemist Adam Johnson, a co-author of the study. "And lightning" — the final catalyst in the equation — "tends to be extremely common with volcanic eruptions."

Luke Leman, a Scripps Institute biochemist who was not involved in the study, published today in Science, agreed.

"These findings add to a growing body of literature suggesting that areas near volcanoes could have been hotspots of organic chemistry on early Earth," he said.

Leman continued, "These findings will likely inspire a next generation of prebiotic chemists, much as Miller's original experimental results have inspired the field for more than fifty years."

Added Bada, "There's a lesson here: don't throw anything away."

Video Podcast #7: Building a Coral Reef from Scratch



Coral reefs in oceans across the world are in trouble. Polluted waters, human encroachment, and ocean acidification are threatening to kill off these ecosystem-creating creatures. Worse, once they're gone, some scientists say it could take millions of years for them to flourish again.

To learn more about how coral reefs -- and the strange animals that build them -- work, we headed out to the California Academy of Sciences' Steinhart Aquarium, where they have built the world's deepest manmade coral reef.

You don't create one of the world's awesomest fish tanks by just dropping some rocks into a pool. The corals require very specific conditions to thrive, so they are hand-placed by divers and their water is kept moving by a complex, underwater engineering system.

In this video, the aquarium's director leads you on a guided tour of his 25-foot deep tank of beautiful fish and surprisingly competitive corals.

Every week, Wired Science will bring you videos on the latest in science, medicine, energy, and space. You can subscribe to the podcast through iTunes, too, so check us out there.

Space Station Renovation: 6 bedrooms/2 baths

3_bedroom_1_bath_2For much of the International Space Station's ten-year life it has been a cramped 3 bedroom/1 bath apartment. But by the end of this year's renovations it will be a substantial 6 bedroom/2 bath house with three lab spaces, a walk in closet and a back porch.

Although the crew reported some trouble with the one on board toilet earlier this week a NASA spokesperson at Moscow mission control said they were able to get it back up and running within a day. Earlier this year when the crew had a problem with the space toilet Russia had to send a replacement pump to the United States in a diplomatic pouch to be carried up on the next Shuttle flight to get it repaired. Although other equipment had to be removed to make room for it, Shuttle payloads manager Scott Higginbotham said, "clearly having a working toilet is a priority for us."

Now the next Shuttle mission to the International Space Station is manifested for November 14th and it will bring sleeping quarters for an three additional crew members, new kitchen equipment, a second toilet, new exercise equipment as well as a new waste water processor that will create more potable water for the station.

All this is currently being packed into 'Leonardo,' the Italian supplied mini-pressurized logistics module that fits into the Space Shuttle's cargo bay. When all the 'movers' are done the first crew of six will be ready to take over the station in May 2009. Until then the current crew may just have to try out all the new bunks to see which one they like best.

Engineers Fix Hubble's Busted Data System

486hubble

NASA engineers will bring the Hubble Space Telescope online tomorrow after two weeks of trouble for the landmark scientific instrument.

A backup system, lying dormant since launch, has successfully been switched on. Using the backup scientific data formatter allowed the team to put the Hubble's old-school 486 computer back in control of the mission's data, an important step in restoring normal operations. 

"If all goes well, the full schedule science observations will start tomorrow morning," said Susan Hendrix, a spokesperson with NASA's Goddard Space Flight Center in Maryland. "We'll be back in normal science mode."

Final tests and calibrations will continue throughout the night, but engineers expect a fully-functioning Hubble to be up-and-running by Friday morning. If that happens, astronomers around the world will breathe a sigh of relief. Two weeks ago, the Hubble encountered an unforeseen error and went into "safe mode," but there were initial fears that the world's favorite space telescope could be bricked. NASA has said they hope to get another decade of observations out of the orbiting craft.

Luckily, the Scientific Data Formatter came with two backup systems. The first was the backup system, called "Side B," that the engineers switched on last night. The second is an entirely new scientific data formatter that NASA has had mothballed on the ground.

Engineers are putting the unit through the paces, and if it checks out, they'll install it during the long-awaited fourth servicing mission for the Hubble. That shuttle mission, initially scheduled for this month, has been pushed back to next year so that the new data formatter can be included in the last shuttle mission to service the HST.

With a Little Help, Near-Extinct Fish Makes Comeback

Pupfish

Tab1brief2grayscalesquared Amidst seemingly endless reports of soon-endangered animals, a bit of good news: the Devil's Hole pupfish is being pulled back from the edge of extinction.

Remants of a species common in an ancient, wetter southwestern United States, the pupfish are now found in a single deep pool near Death Valley, where an isolated colony has survived for 10,000 years. Only 36 were found when scientists counted them in 2006, down from 500 a decade ago.

But thanks to a U.S. Fish and Wildlife Service feeding program, those numbers are up to 126 [.pdf] -- still a fragile population, but headed in the right direction. And none of this would be possible without a landmark 1976 Supreme Court ruling that nearby ranch owners were not entitled to pump water from Devil's Hole if it destroyed the species.

Darn those activist judges!
