Take my taxi to the moon






















Susmita Mohanty, the founder of India’s first private space company, Earth2Orbit, wants India to claim bigger piece of the space-launch pie






















How active is India's space programme?
The Indian Space Research Organization (ISRO), which was founded in 1969, launches rockets, builds and uses satellites extensively for earthly applications and has recently started planetary exploration. It tested its first astronaut capsule for atmospheric re-entry in 2007, and is planning to build a residential astronaut training facility. ISRO is also planning a lunar lander mission for 2014 and will launch a mission to Mars this year.












How does your company, Earth2Orbit, fit in with this programme?
We want to commercialise India's space capabilities, in particular the Polar Satellite Launch Vehicle. It is one of the world's most reliable in its class. I want to make it the rocket of choice for international satellite-makers looking to get to low Earth or sun-synchronous orbits. India could build and launch up to six each year, but currently launches only two. We need to step up to full throttle. The same goes for satellites and ground equipment. Over the next decade or two, I think India should be aiming for at least a quarter of the multibillion-dollar global space market, if not more.












What do you think of the way spacecraft for carrying humans are currently designed?
The way the world aerospace industry is set up, it is closely linked to the defence sector – they share the technology, the tooling and the cumbersome contractual processes. Unlike commercial automobile or consumer-product companies, where the end user is the primary design driver, aerospace companies tend to please government customers. As a result, we often end up with over-engineered, under-designed crew craft with an exorbitant price tag.












How can we improve on these designs?
I want us to push the boundaries of technology and design and build intelligent spaceships – spaceships that think. Imagine if an international consortium of companies such as Apple, Samsung, Pininfarina, Space X and MIT Media Lab got together to design and build a spaceship! What would it look like? Could it think? Could it self-repair or self-clean? Would it challenge the crew?












The private sector is changing how we get into space. How has the X Prize contributed?
It created a tectonic shift in mindsets and showed how we can accelerate innovation in space exploration without having to spend taxpayer money. The first X Prize led to the first privately funded and designed spaceplane built by Burt Rutan. Then Richard Branson seized the opportunity: if all goes well, Virgin Galactic could fly more people to space in a year than the Russians or Americans have over the past 50 years!












What is next for space travel?
It barely takes 10 minutes to reach low Earth orbit. It probably takes longer for most urbanites to commute to work. I want to be able to "cab it" to low Earth orbit. I am dreaming of private astronaut taxis. The first generation will take paying passengers into orbit. The second generation will ferry us to the moon and Mars.

Revisit issue of investigation into police brutality after proceedings end: Indranee






SINGAPORE: Issues relating to the investigation of claims of police brutality by former SMRT bus drivers will be dealt with once relevant proceedings are over.

Senior Minister of State for Law, Indranee Rajah, said this in Parliament on Monday.

She was responding to a question by Non-Constituency Member of Parliament, Yee Jenn Jong.

Mr Yee asked whether the attempted retention and confiscation of a laptop, desktop computer and mobile phone belonging to a film maker was in accordance with requirements set out in the Criminal Procedure Code.

He also questioned what the legal basis is for the attempted confiscation.

Ms Indranee said the allegations of police brutality against the former SMRT drivers, which were posted on the website "Lianain Films" on 28 January, are serious allegations.

They are currently being investigated by the Police Internal Affairs Office.

She said notwithstanding these allegations, the drivers have indicated through their counsel that they intend to plead guilty to the criminal charges preferred against them.

Ms Indranee added that it is best that the issue is dealt with after all the relevant proceedings are over.

STORY HIGHLIGHTS


  • NEW: Flights in and out of Amarillo International Airport have been canceled

  • NEW: Portions of I-40 and U.S. Highways 87 and 187 in Texas are closed

  • Kansas Gov. Sam Brownback is calling on drivers to stay off the road

  • "This storm has the potential to be more dangerous than last week's storm," he says




(CNN) -- Call it winter weather, part two.


Just days after a storm walloped the Great Plains, a second one, bringing with it heavy snow and strong winds, was slamming the region early Monday, forcing airline cancellations and school closures from Colorado to Texas.


National Weather Service forecasters warned the storm was bringing potentially "life threatening" and "crippling" blizzard conditions with freezing temperatures to portions of southeast Kansas, northwest Oklahoma and the Texas panhandle overnight.


All flights in and out of Rick Husband Amarillo International Airport in Texas were canceled until noon on Monday.


"Nothing coming in or out until then at the earliest," airport spokesman Daryl Ware said.


A number of schools districts, senior centers and churches were closed in Oklahoma and the Texas Panhandle until at least Tuesday, while some state and local offices were also being temporarily shuttered.


Fearing a repeat of last week's storm that brought more than 22 inches of snow to some places in Kansas, forcing the closure of airports and schools, the governor on Sunday extended a state of emergency declaration to include the new storm.


Kansas City is expecting 9 to 15 inches of snow Monday night into Tuesday, according to the National Weather Service, and officials are calling for residents to stay off the roads.


"This storm has the potential to be more dangerous than last week's storm," Kansas Gov. Sam Brownback said late Sunday. "So, we ask you to stay off the road unless it's absolutely critical. If you have to be out, be prepared with a charged cell phone, an emergency kit with food, water, blankets, flares and a shovel."


'Call it a win'


Such forecasts raised alarms throughout the Plains, leading to crowded stores as residents prepared for the storm.


Amanda Roberts, an entrepreneur and blogger in Warrensburg, Missouri, hit the stores ahead of the storm that is expected to start hitting the state by late Monday.


"The snow has everyone stocking up on groceries," she said in a Twitter post. "Fresh produce is basically gone but I got the last gallon of chocolate milk. I call it a win."


Forecasters have upped their predictions for the amount of snow expected in northwest Oklahoma to 8 to 10 inches, with 15 inches in spots. This may be a shock to some, given that temperatures in places reached the mid-60s on Sunday.


"May see 4-6 foot drifts!" wrote National Weather Service meteorologist Rick Smith on Twitter. "Traveling is beyond discouraged!"


In Texas, the Department of Transportation closed portions of westbound I-40 from outside from Amarillo to Albuquerque, New Mexico, because of blizzard conditions.


The Texas Department of Public Safety, meanwhile, closed portions of U.S. Highways 87 and 187 due to overnight white out conditions expected to continue through Monday afternoon.


Salt truck drivers were on standby overnight in Oklahoma City.


"Well, we're pretty well prepared right now. We have 28 trucks loaded, plows on," Oklahoma City Emergency Management's Mike Love told CNN affiliate KWTV.


"We run our emergency snow route. We'll run that until it's free and clear. And if this stuff comes in like they're saying tomorrow, with these high winds, look forward to some drifting."


By early Monday, with more than 9 inches of snow reported in some areas of Denver, airline operations in the Colorado capital were working to return to normal a day after more than 200 of 1,500 flights had been canceled and hundreds more flights were delayed because of the weather, according to the Federal Aviation Administration.


Up to 19 inches of snow was reported in Jefferson, about 70 miles southwest of Denver.


Rain, flooding the issue in Southeast


While millions will see snow -- including Chicago, where 3 to 5 inches of snow and sleet are expected Tuesday -- rain may rule for the next few days in parts of the Southeast.


In Mobile, Alabama, on the Gulf Coast, residents prepared for the possibility of heavy rains and wind gusts as strong as 30 mph by Monday night.


The rain is part of a band affecting five Southeastern states where flash flood watches are in effect from Monday afternoon through Tuesday morning.


Some areas from Louisiana to South Carolina could see up to 4 inches of rain.


Record-setting February


Kansas City International Airport set a February 21 record of 9 inches of snow, 4 more inches than the amount that fell the same date in 2010. Monday might bring 6 to 10 more inches, forecasters said.


Kansas City is approaching its February snowfall record of 20.7 inches, set in 1960.


The state of Kansas is also still digging out in many places.


Wichita saw its second-highest storm snowfall total on record last week with 14.2 inches over two days, the National Weather Service said.


The town of Russell in the state's middle lay under a 22-inch layer of white by the time the storm roared by.


CNN's AnneClaire Stapleton and Judson Jones contributed to this report.

Oscars 2013: 'Argo' Wins Best Picture












"Argo" took home the top prize as best picture at the Oscars Sunday night, with first lady Michelle Obama announcing the winner from the White House.


"You directed a hell of a film," co-producer Grant Heslov told director and fellow producer Ben Affleck. "I couldn't be more proud of the film and more proud of our director."


Affleck was snubbed in the directing category but humbly accepted the best picture Oscar as one of the three producers on the film. George Clooney was the third.


Affleck thanked Steven Spielberg and the other best picture nominees and his wife Jennifer Garner for "working on our marriage."


"It's good, it's work," he said, adding, "but there's no one I'd rather work with."


For Full List of Winners


Acknowledging his last Oscar win, as a screenwriter for "Good Will Hunting," Affleck said, "I was really just a kid. I never thought I would be back here."


In the acting categories, Daniel Day-Lewis won the Oscar for best actor, being the first actor to three-peat in that category. As he accepted the award from Hollywood's greatest actress, Meryl Streep, he joked, "I had actually been committed to play Margaret Thatcher. ... Meryl was Stephen's first choice for Lincoln."


He also thanked his wife, Rebecca Miller, for "living with some very strange men," with each new role that he takes on.


"She's the versatile one in the family and she's been the perfect companion to all of them," he said.

Jennifer Lawrence won the award for best actress. She tripped on the stairs on her way to accepting her award but picked herself up and made her way to the stage, earning a standing ovation.


"You're just standing up because you feel bad that I fell and that's embarrassing," she said, before rattling off a list of thank-yous and leaving the stage looking slightly stunned.

"Life of Pi," which had a total of 11 nominations, was another big winner of the night. Director Ang Lee took home the Oscar for best director over Steven Spielberg and David O. Russell.


"Thank you, movie god," Lee said, accepting his award.


As expected, the film took home the first technical awards of the night for cinematography and visual effects. "Life of Pi" also won for best original score.


The first big acting awards of the night went to Christoph Waltz and Anne Hathaway in the supporting actor categories.


In one of the biggest tossups, Waltz claimed the award for supporting actor for his role in "Django Unchained." It was his second Oscar for a Quentin Tarantino film; his first was for Tarantino's "Inglourious Basterds."

As expected, Hathaway took home the award for best supporting actress for her role as Fantine in "Les Miserables."


"It came true," she said, launching into a breathy speech, in which she thanked the cast and crew, her team and her husband. "The greatest moment of my life was when you walked into it," she said.


Tarantino won the Oscar for best original screenplay for his slave revenge western "Django Unchained." He thanked his cast.


"I have to cast the right people," he said. "And boy this time did I do it."


Chris Terrio won the award for best adapted screenplay for "Argo," which also won for film editing.


For only the sixth time in Academy history, there was a tie at the Oscars. "Zero Dark Thirty" and "Skyfall" tied for sound editing.

Several dead in Vietnam house explosions






HANOI: Several people were killed when twin blasts tore through a residential street and destroyed three houses in south Vietnam early Sunday, police said, with reports putting the death toll at around 10.

"We have been informed of two explosions this morning that killed about ten people... but we need to check the exact number of the victims," a local policeman told AFP following the blasts, which left many more victims trapped in rubble, according to reports.

The policeman said authorities were investigating the cause of the explosions in a district of the southern metropolis of Ho Chi Minh City, adding that they were believed to have been accidental.

State mouthpiece Tuoi Tre newspaper reported on its website that a family of seven was among those killed and many people remained trapped in the rubble.

It said local people heard two large explosions within five minutes of each other -- causing shockwaves that rattled homes up to several hundred metres away. They discovered three homes ablaze and partially destroyed.

Hundreds of firefighters on more than a dozen fire trucks rushed to the scene and were leading rescue efforts, the newspaper said.

STORY HIGHLIGHTS


  • NEW: Texas man had surgery after suffering leg gash but is "doing fine," brother says

  • The multicar crash happens at the end of a Nationwide Series race in Daytona speedway

  • Debris, including an engine, ends up airborne -- some reaching the stands' second level

  • 12 patients are at one hospital, two of them in critical but stable condition, official says




Were you at the speedway during the crash? If you were recording video of the crash or took photos, upload them to CNN iReport.


(CNN) -- Debris flew into the stands, injuring a number of spectators -- at least two of them critically -- during a jaw-dropping crash Saturday in the final turn of a NASCAR race at Daytona International Speedway.


The multicar crash occurred near the end of the Nationwide Series Drive4COPD 300 race at the same Florida track where Sunday's Daytona 500 will be held.


The race had recently restarted after another wreck, after which driver Michael Annett was hospitalized for bruising to his chest, according to Richard Petty Motorsports.


Several closely-packed cars were jostling for position at top speed when they got tangled up, setting off a dangerous chain reaction that ensnared a number of vehicles.


Reigning Sprint Cup champ Brad Keselowski -- who later told CNN he and others were simply "going for the win" -- was among those involved, while Tony Stewart somehow emerged unscathed and finished by winning the race.


Driver Kyle Larson's vehicle ended up flying into a fence that separates the track from spectators. It broke into pieces -- including tires and a fiery engine.


Larson walked away from the crash, even after the front part of his No. 32 car was completely gone. He and the other nine drivers involved told reporters that they were checked at a medical tent on the Daytona infield and released.


Some of the shredded debris flew into the barrier, while others got into the stands -- some of it reaching the second level about 20 feet up.


A video posted on YouTube shows a cloud of debris flying into stands and one man gasping, "Oh, my God." A tire rests on one seat, as a man frantically waves and yells to get the attention of paramedics.


Afterward, several spectators could be seen lying down after apparently suffering injuries. A line of about 10 ambulances lined up on the track, with some first responders carrying stretchers.


Fourteen fans were treated at an on-site medical facility, while 14 others were transported to area hospitals, speedway president Joie Chitwood told reporters.


"I'm just hoping everyone is OK," said Keselowski. "As drivers, we assume the risk. But fans do not."


NASCAR president Mike Helton earlier told ESPN, which was broadcasting the race, some people were taken to Halifax Health Medical Center. He said the protective fence did its job in preventing potentially more injuries and possibly deaths.


Byron Cogdell, a spokesman for the hospital, told CNN that his facility was treating 12 patients. Two of those -- one of them a child -- are in critical but stable condition.


"Everybody appears to be in stable condition," Cogdell said.


Staff at Florida Hospital Memorial Medical Center were treating one person and expecting three more, spokeswoman Lindsay Rew said Saturday evening.


The injured include Eddie Huckaby, a 53-year-old Krum, Texas, resident who suffered a leg gash when a large piece of metal hit him as he was watching the race, his brother Terry Huckaby told CNN affiliate WKMG. He described the motor landing in the stands, as well as a wheel "and everything flying over your head and debris everywhere."


"He's doing fine," Terry Huckaby said of his brother, who underwent surgery at Halifax Health Medical Center. "The first thing he said, 'I don't want to miss that (Daytona 500) race, but I have to watch on TV.'"


Accidents are nothing new to NASCAR, where cars often cruise at speeds topping 190 mph, nor to the Daytona track. One of the sport's most horrific, and well-known, wrecks happened in the 2001 Daytona 500, when famed driver Dale Earnhardt Sr. was killed -- also, on that race's final lap.


Still, injuries and fatalities to spectators are much rarer.


With the stands having been quickly evacuated, crews worked to repair the damaged fence. Chitwood expressed confidence the 55th edition of the Daytona 500 would go on as planned, with spectators even sitting in the same seats struck by debris Saturday.


"With the fence being prepared tonight to our safety protocols, we expect to go racing tomorrow with no changes," Chitwood said.


CNN's John Newsome and Joe Carter reported from Daytona Beach, while Greg Botelho wrote this story from Atlanta. CNN's Phil Gast, Dan Moriarty, Scott Thompson and Janet DiGiacomo contributed to this report.

Daytona crash sends car parts flying, injuring fans

Updated at 9:35 p.m. ET


DAYTONA BEACH, Fla. At least 33 fans were injured Saturday during a NASCAR race when a car flew into the fence at Daytona International Speedway, hurling a tire and large pieces of debris into the stands.

The accident happened on the last lap of the second-tier Nationwide Series race on the eve of Sunday's Daytona 500, which officials said would go on as scheduled.

The crash began as the field approached the checkered flag and leader Regan Smith attempted to block Brad Keselowski to preserve the win. That triggered a chain reaction, and rookie Kyle Larson hit the cars in front of him and went airborne into the fence.

The entire front end was sheared off Larson's car, and his burning engine wedged through a gaping hole in the fence. Chunks of debris from the car were thrown into the stands, including a tire that cleared the top of the fence and landed midway up the spectator section closest to the track.

The 20-year-old Larson stood in shock several yards away from his car as fans in the stands waived frantically for help. Smoke from the burning engine briefly clouded the area, and emergency vehicles descended on the scene.

Ambulance sirens could be heard wailing behind the grandstands at a time the race winner would typically be doing celebratory burnouts.

"It was freaky. When I looked to my right, the accident happened," said Rick Harpster of Orange Park, Fla., who had a bird's-eye view of the wreck. "I looked over and I saw a tire fly straight over the fence into the stands, but after that I didn't see anything else That was the worst thing I have seen, seeing that tire fly into the stands. I knew it was going to be severe."

Daytona International Speedway released a statement from speedway President Joie Chitwood Saturday evening saying 28 people were injured in the accident in the race held the day before the season-opening Daytona 500.

Daytona racecar loses control




According to the statement, emergency medical personnel transported 14 people off the property and 14 others were treated at the on-track care center.

"We are in the process of repairing the facility, and we will be ready to go racing tomorrow," Chitwood said.

Nathan Kimpel, 24, who works at a concession stand near where the crash happened, told CBS News correspondent Adriana Diaz that he saw 10 to 15 fans being carried out on stretchers.

"As soon as I saw the accident I just turned my head because I didn't want to get injured or anything," Kimpel told Diaz. "I saw the fence separate and more pieces of car parts flying up."

Meghan Willams, 20, who also works at a concession stand, told Diaz the crash sounded like an "earthquake." She saw people running and crying and a girl completely covered in engine oil.

Byron Cogdell, a spokesman for Halifax Health Medical Center, told CBS News that one of the 11 patents taken to the hospital was in critical condition and five more were listed as "trauma" patients.

Lindsay Rew, a spokeswoman for Florida Hospital Memorial Medical Center, said its Daytona Beach hospital had one fan there who was in good condition. She said they were expecting three more people who were coming by ambulance, but she didn't yet know their conditions.

"There obviously was some intrusion into the fence and fortunately with the way the event's equipped up, there were plenty of emergency workers ready to go and they all jumped in on it pretty quickly," NASCAR President Mike Helton said. "Right now, it's just a function of determining what all damage is done. They're moving folks, as we've seen, to care centers and take some folks over to Halifax Medical."

As emergency workers tended to injured fans and ambulance sirens wailed in the background, a somber Tony Stewart skipped the traditional post-race victory celebration.

Stewart, who won for the 19th time at Daytona and seventh time in the last nine season-opening Nationwide races, was in no mood to celebrate.

"The important thing is what going on on the frontstretch right now," said Stewart, the three-time NASCAR champion. "We've always known, and since racing started, this is a dangerous sport. But it's hard. We assume that risk, but it's hard when the fans get caught up in it.

"So as much as we want to celebrate right now and as much as this is a big deal to us, I'm more worried about the drivers and the fans that are in the stands right now because that was ... I could see it all in my mirror, and it didn't look good from where I was at."

The accident spread into the upper deck and emergency crews treated fans on both levels. There were five stretchers that appeared to be carrying fans out, and a helicopter flew overhead. A forklift was used to pluck Larson's engine out of the fence.

"It's a violent wreck. Just seeing the carnage on the racetrack, it's truly unbelievable," driver Justin Allgaier said.

It was a chaotic finish to a race that was stopped for nearly 20 minutes five laps from the finish by a 13-car accident that sent driver Michael Annett to a hospital, where his Richard Petty Motorsports team said he would be held overnight with bruising to his chest.

The race resumed with three laps to go, and the final accident occurred with Smith trying to hold off Keselowski through the final turn.

"I tried to throw a block. It's Daytona, you want to go for the win here," Smith said. "I don't know how you can play it any different other than concede second place, and I wasn't willing to do that today. Our job is to put them in position to win, and it was, and it didn't work out."

As the cars began wrecking all around Smith and Keselowski, Stewart slid through for the win, but Larson plowed into Keselowski and his car was sent airborne into the stands. When Larson's car came to a stop, it was missing its entire front end. The 20-year-old, who made his Daytona debut this week, stood apparently stunned, hands on his hips, several feet away from his car, before finally making the mandatory trip to the care center.

He said his first thought was with the fans.

"I hope all the fans are OK and all the drivers are all right," Larson said. "I took a couple big hits there and saw my engine was gone. Just hope everybody's all right."

"Honestly, the race itself pales in comparison to the injuries sustained by the fans," said Chip Ganassi, the team owner who has Larson in his driver development program. "Our thoughts and prayers go out to all the fans that were injured as a result of the crash. As for Kyle, I am very happy that he is OK."

Keselowski watched a replay of the final accident, and said his first thoughts were with the fans. As for the accident, he agreed he tried to make a winning move and Smith tried to block.

"He felt like that's what he had to do, and that's his right. The chaos comes with it," Keselowski said. "I made the move and he blocked it, and the two of us got together and started the chain events that caused that wreck. First and foremost, just want to make sure everyone in the stands is OK and we're thinking about them."

Keselowski said the incident could cast a pall on the Daytona 500.

"I think until we know exactly the statuses of everyone involved, it's hard to lock yourself into the 500," Keselowski said. "Hopefully, we'll know soon and hopefully everyone's OK. And if that's the case, we'll staring focusing on Sunday."

Las Vegas Strip Shooting Suspect ID'd












Las Vegas police identified a suspect today in a shooting on the strip that caused a Maserati to hit a taxi and burst into flames, killing three people.


Ammar Harris, 26, has been named a suspect in the Thursday skirmish that killed three people, including rapper Kenny Clutch.


The altercation between Harris and Clutch, 27, whose legal name was Kenneth Cherry Jr., is believed to have originated in the valet area of a Las Vegas hotel, police said.


Police said Harris fired several rounds into a Maserati that was being driven by Cherry as both vehicles continued northbound on glitzy Las Vegas Boulevard.


The rapper's expensive sports car careened out of control after he was shot, slamming into several cars, including a taxi. The impact caused the cab to burst into flames, killing the driver, Michael Boldon and a female passenger. Witnesses said it looked like the car exploded.


"He was a number one guy," Carolyn Jean Trimble, Boldon's sister, told ABC News.

"I looked out my window and I could see one vehicle down here on the corner of the intersection totally engulfed in flames," witness John Lamb told ABC News.


Boldon, 62, and his passenger, who has not yet been identified, were both killed, as was Clutch.


Timble said her brother loved driving his taxi around Vegas.


"He came to live with me in Las Vegas last year to help take care of our mother, and the first day he got here he said, 'I have to get a job.' The second day, I came home from work, and he said he got a job," she recalled.


"He says, 'You'll never guess what it is,' and I said, 'what,' and he said, 'taxi cab driver,' and we both fell out laughing," Trimble said. "He loved that job. He never complained. He'd come home and tell me stories about what happened, who he picked up."


Boldon was a single father who raised a 36-year-old son and was a new grandfather. His grandson was named after him, Trimble said.


"Of all the people to take from this earth," she said. "But I guess the Lord needed him."


A passenger in the Maserati was hit and sustained only a minor injury to his arm. Clutch died at University Medical Center.


His father, Kenneth Cherry Sr., expressed his grief for the loss of his son while speaking with ABC News.


"This is something you never really, really ever want to experience as a parent, to lose a child before you go," he said.


Harris is described as 5-foot-11 and 180 pounds. Anyone with information is asked to contact the Las Vegas Metro Police Department's homicide division.

Rusty rocks reveal ancient origin of photosynthesis



































SUN-WORSHIP began even earlier than we thought. The world's oldest sedimentary rocks suggest an early form of photosynthesis may have evolved almost 3.8 billion years ago, not long after life appeared on Earth.











A hallmark of photosynthesis in plants is that the process splits water and produces oxygen gas. But some groups of bacteria oxidise substances like iron instead – a form of photosynthesis that doesn't generate oxygen. Evolutionary biologists think these non-oxygen-generating forms of photosynthesis evolved first, giving rise to oxygen-generating photosynthesis sometime before the Earth's atmosphere gained oxygen 2.4 billion years ago (New Scientist, 8 December 2012, p 12).













But when did non-oxygen-generating photosynthesis evolve? Fossilised microbial mats that formed in shallow water 3.4 billion years ago in what is now South Africa show the chemical fingerprints of the process. However, geologists have long wondered whether even earlier evidence exists.












The world's oldest sedimentary rocks – a class of rock that can preserve evidence of life – are a logical place to look, says Andrew Czaja of the University of Cincinnati in Ohio. These rocks, which are found in Greenland and date back almost 3.8 billion years, contain vast deposits of iron oxide that are a puzzle. "What could have formed these giant masses of oxidised iron?" asks Czaja.


















To investigate, he analysed the isotopic composition of samples taken from the oxidised iron. He found that some isotopes of iron were more common than they would be if oxygen gas was indiscriminately oxidising the metal. Moreover, the exact isotopic balance varied subtly from point to point in the rock.












Both findings make sense if photosynthetic bacteria were responsible for the iron oxide, says Czaja. That's because these microbes preferentially oxidise only a small fraction of the dissolved iron, and the iron isotopes they prefer vary slightly as environmental conditions change (Earth and Planetary Science Letters, doi.org/kh5). His findings suggest that this form of photosynthesis appeared about 370 million years earlier than we thought.












It is "the best current working hypothesis for the origin of these deposits", says Mike Tice of Texas A&M University in College Station – one of the team who analysed the 3.4-billion-year-old microbial mats from South Africa.












William Martin at the University of Düsseldorf, Germany, agrees. "Anoxygenic photosynthesis is a good candidate for the isotope evidence they see," he says. "Had these fascinating results been collected on Mars, the verdict of the jury would surely remain open," says Martin Brasier at the University of Oxford. "But [on Earth] opinion seems to be swinging in the direction of non-oxygen-generating photosynthesis during the interval from 3.8 to 2.9 billion years ago."
