Editor’s note:Life’s Work” features innovators and pioneers who are making a difference in the world of medicine.The names of some fistula patients have been changed to protect their privacy.

(CNN) — It’s a condition practically unheard of in the United States and most Western countries. But in a culture where a woman’s status and dignity is decided by her ability to provide a husband with multiple children, it can be a fate worse than death.

“Obstetric fistula” is a mouthful. But to these women, it’s much more than just a physical injury. They see themselves as the walking dead, says Dr. Justin Paluku Lussy, head of the department of obstetrics and gynecology at HEAL Africa Hospital in Goma, Democratic Republic of the Congo.

An obstetric fistula occurs when a woman withstands days of obstructed labor, when a baby’s head is constantly pushing against her pelvic bone during contractions — preventing blood flow and causing tissue to die.

This creates a hole, or a “fistula,” between a woman’s vagina and her bladder or rectum. Her baby is unlikely to survive. If the mother lives, she is unable to hold her urine and, in some cases, bowel content, Paluku Lussy says.

A woman with a fistula, who is perpetually leaking urine and sometimes feces, is often rejected by her husband and shunned by her village because of her foul smell and inability to bear more children.

“These women have so much shame and so much fear. They spend so much money on perfume trying to cover up the smell,” says Alison Heller, a doctorate student at Washington University in St. Louis who is leading a research study of 50 women in Niger awaiting fistula surgery. The women range in age from 15 to 70.

Tanzanian women find hope in corrective surgery

An estimated 20% of Paluku Lussy’s fistula patients report feeling ostracized by their communities, and divorce is common, says the doctor, who started his residency in 2001 at HEAL Africa, a 155-bed tertiary hospital with a fistula repair unit.

“People think fistula patients are witches and just have bad luck,” he says.

Although an estimated 2 million women in Asia and sub-Saharan Africa live with untreated obstetric fistula, according to the Fistula Foundation, it’s unlikely for these women to meet or hear of anyone else suffering from the same injuries, because of the lack of modern forms of communication and also the women’s reluctance to discuss the condition, Heller says.

In most cases, a woman with a fistula doesn’t know what a fistula is or that it’s treatable with surgery. And if she does, she is far from any hospital and doesn’t have money for — or access to — transportation, let alone the average $450 cost for repair surgery plus postoperative care.

One of the youngest in Heller’s study, a 15-year-old girl who was married off to her uncle at age 8, spent eight months selling bags of candied peanuts in order to raise enough money to pay for a taxi so she could get to a fistula center.

Such concerns are foreign concepts to most Westerners, says Dr. Lewis Wall, a professor of obstetrics and anthropology at Washington University in St. Louis. That’s because obstetric fistulas were largely eradicated from the United States by the 20th century, with strides in prenatal care and the use of cesarean section.

But pregnancy complications and childbirth are among the leading causes of death and disability for African women, Wall says.

Mom’s death inspires doctor’s life work

Typical West African hospitals do not have the trained staff or resources to identify and treat fistulas, Heller says.

“Habsu,” one 32-year-old woman in Heller’s study, contracted a fistula in her ninth pregnancy and has had three previous surgeries, all of which have failed. During the latest pregnancy, she was in labor for several days at home in a rural village before receiving medical care. Like many African women, she was malnourished and her pelvic bones were too small for a natural birth.

After hours of unsuccessful labor and not knowing how to perform a cesarean, the doctors used a scalpel to sever the baby inside the woman’s birth passage. Over the next few days, the mother delivered her baby, piece by piece, Heller says.

Another West African woman in Heller’s study, “Amina,” also has a severe fistula but only leaks when she sits down. After the seated interview with Heller, Amina apologized, saying she would leak urine once she stood up.

“It was as if a gallon of water was thrown to the ground,” Heller says. “She was so ashamed.”

Many Africans — both educated and uneducated — believe there is no cure for fistulas, Paluku Lussy says. When he was in medical school at the University of Goma, he says, “they used to tell us not to even try to fix them.”

But, he says, that’s not the case. Fistulas can be repaired with delicate surgery, which has a fairly good success rate. However, surgeons must be well-trained in the principles of the operation, and good follow-up care is essential so the surgery won’t fail. Patients with more severe fistulas may need multiple surgeries.

Too many mothers still dying

Although he is a full-time professor, Wall last year opened the Danja Fistula Center in Niger, a 42-bed hospital specializing in fistula repair surgeries with an operating room, outpatient clinic and hostel facilities for about 100 women.

Since opening the fistula center, Wall estimates the facility has taken on 50 fistula cases per month.

But it’s very difficult to get trained staff to run a fistula hospital, because of the lack of available education in Africa, he says. Fistula centers rely on donations and cannot afford to hire American gynecologic surgeons.

But even they aren’t ideal candidates for the job — since they never see fistula in their own country, they have no experience with it, he says. It’s best to have the institution run by locals trained specifically in fistula repair surgery and care.

Those who want to help should focus on spreading the word — awareness is key, he says. Thursday is the first International Day to End Obstetric Fistula; the United Nations Population Fund will host a variety of events to raise awareness.

That’s true for Washington resident Olivia Bowen. She had never heard of obstetric fistula until she read a book featuring a detailed story of an African woman with the condition. Bowen was shocked at how affordable fistula repair surgery is, by Western standards.

Bowen started a fundraiser called “One Week to End Fistulas,” which raises money for repair surgeries for underprivileged women who otherwise lack access. She asks that participants practice yoga daily for a week and raise enough money for one woman to have fistula repair surgery.

“I’m not a runner. I do yoga. So it’s something that just came naturally to me,” Bowen says.

So far, participants have raised about $2,250, or enough to fund five surgeries.

Bowen, who is in the process of making the fundraiser a nonprofit organization, says she hopes to help women who have already developed fistula, while the bigger organizations tackle other issues such as poverty, maternal health and human rights. Ultimately, she says, fistula is not just a women’s issue; it’s a human issue.

Microsoft to launch Kinect for Windows sensor in 2014

Microsoft will finally deliver a Kinect sensor for Windows sometime next year.

The company announced Thursday that the Kinect for Windows sensor will use the same set of technologies key to the new Kinect sensor for the
Xbox One, both of which will allow people to issue commands using voice and gestures.

The sensor will include a high-definition color camera and a noise-isolating multi-microphone array. Also part of the system will be a technology called Time-of-Flight, which measures how long it takes for photons to bounce off a person or object. Combined, these features promise greater accuracy and precision in detecting your movements and voice commands.

Like its Xbox One counterpart, the Kinect for Windows sensor will be able to pinpoint more parts of the body, opening up more accurate skeletal tracking. The sensor will also use a greater field of view to handle a variety of room sizes. A new infrared feature will help the sensor “see” better, especially in darker conditions.

The launch of the Kinect for Windows sensor and the corresponding software development kit means that developers will be able to create apps that take advantage of the features.

“We’re continuing our commitment to equipping businesses and organizations with the latest natural technology from Microsoft so that they, in turn, can develop and deploy innovative touch-free applications for their businesses and customers,” Microsoft said in a blog post Thursday. “A new Kinect for Windows sensor and software development kit (SDK) are core to that commitment.”

The Last Of Us Preview

The Last Of Us Preview

Platform: PS3
Developer: Naughty Dog
Publisher: Sony Computer Entertainment

The Last Of Us is about scarcity. It’s about making do. That’s not just key to the way combat’s designed, it’s true of the entire development process. Seemingly The Last Of Us is about discovering what else you can provide in a game besides shooting another human. Figuring that out makes the moments where killing is inevitable stick out that much more prominently.

The Last Of Us Preview

It’s probably not a coincidence that this echoes the setting. It’s a Cormac McCarthy-esque post apocalypse where only remnants of the current world still stand, ravaged by time. The majority of the population have been wiped out by a plant-borne infection that turns them rabid, but they’re only a portion of the threat to those that are left. Bandits roam the world trying to survive in less than admirable ways. There’s little to find in the world but danger.

Our preview build showed two brief slices early into the game’s narrative. The first contains an extended walk without seeing a single human that isn’t your character Joel or companion Ellie. They intend to meet with a friend holed up further into an abandoned town, in an attempt to barter for a car. The player is totally denied any sense of threat along the way, making it incredibly disturbing as the tension ratchets up in anticipation of what will inevitably come.

The Last Of Us Preview

Along this walk there are a few puzzles. You have to get over a fence but it’s covered in barbed wire. You’ll notice a long plank of wood leaning against a wall which sure enough you can pick up. By climbing atop other nearby structures you can use the plank to create a bridge. Easy.

However, dropping the plank just slightly out of range of the correct position means that Joel will lay it down on the ground next to him. It’s a peculiar break in the sense of immersion; one minute the world feels real and malleable, the next you realise you’ve encountered something akin to a quicktime event. For a game that presents itself as so cinematic to suddenly remind you of the medium’s flaws makes them all the more notable. Hopefully in the full game these moments will be the exception rather than the rule.

The Last Of Us Preview

While on your travels you can scavenge for supplies along the way. Everything you find is a consumable and mostly they’ll be converted into more useful materials. There’s a crafting system that you can access at any time, but terrifyingly it doesn’t pause the game. As such you’ll want to make preparations when you think you’re safe, especially as the equipment you’re crafting is important during combat.

On top of the risks of creating in real time, you’ll also have to choose carefully what you craft. Many items can serve multiple perhaps and be combined in a number of different ways, such that you could create a health pack or a molotov cocktail, say. For example, you can duct tape a pair of scissors to your melee weapon for two instant kills with it before they snap off, or you could fashion a shiv that can either be used for a single silent kill or break open the lock on a door. Even the weapon you’ve selected needs to be considered before a fight breaks out. You’ve a variety in your pack, but you’ll need to lay it down and root around for the one you’ll grab when necessary. That’s your choice and you don’t have the luxury of knowing what you’ll need for the situation, nor the time to decide once you’re up against it.

We do take umbrage with some of these decisions as it’s just as “unrealistic” that you wouldn’t think to fashion useful holsters for key weapons, or keep items in pockets, rather than have them all tucked away in a bag. Likewise it’s nonsense that a shiv should be single-use. Again, it’ll be interesting to see how these slight irritations feel in the full game.

The Last Of Us Preview

When, in this preview, you’re finally attacked you’re vastly outnumbered and your only option is to run, briefly thinning out attackers who get too close to you or Ellie. Here she runs the risk of being too dependant, in stark contrast with the way that Bioshock Infinite handled the secondary protagonist of Elizabeth. Whenever she’s attacked she’ll require your help. This does of course make sense as Ellie is a young girl without the ability to rip holes in spacetime, but still. At best this’ll force you to be more bold in your combat to save her and make for better gameplay, but if it follows most other games the entire game runs the risk of feeling like an escort quest. It’d be a shame, because through dialogue Ellie is made about as great a character as only Naughty Dog appears to be able to provide. She’ll win you over the first time she calls someone a Motherf*cker, trust me.

The Last Of Us Preview

The second glimpse of combat, a little later in the story, focused specifically on an attack by a manageable but still massive number of bandits. The combat is brutal and meaningful. It’s not something that you’re going to want to get involved in and you’re going to have to think carefully about how to handle yourself. Breaking line of sight and catching an attacker unawares is the only upper hand you have. You’ll run out of bullets if they aren’t used sparingly and you’ll be beaten bloody in any melee encounter if there’s more than one person around. You don’t want to get in fights, but you will. You’ll have to deal with the consequences when it happens.

Overall we’re so far impressed with what The Last Of Us has to offer and if the full game lives up to the preview build it’ll be well worth picking up. As one of the last major new titles for the PS3, before the PS4 arrives, it could make for a superb swansong for the console.

Survey: Teens Facebook weary


A new survey suggests some U.S. teens may be losing interest in Facebook, although they remain active on the site.

(CNN) — There’s fresh evidence that American teenagers may be growing weary of Facebook.

They don’t like the fact that their parents, grandparents and other adults are also there, diluting Facebook’s “cool” factor. They complain about their friends’ oversharing, and about too much “drama” on the site. And they’re increasingly flocking to other social platforms, such as Twitter.

These are some of the findings of a new Pew Research Center survey of U.S. teens’ social media use. Released Tuesday, the survey finds that teens are sharing more personal information on social media, but are also taking a variety of steps to manage their privacy online.

But it was the Facebook stuff that generated the most headlines. According to Pew, focus-group discussions with teens revealed “waning enthusiasm” for Facebook for the reasons cited, including feeling “drained by the ‘drama’ that they described as happening frequently” on the site.

“The stress of needing to manage their reputation on Facebook also contributes to the lack of enthusiasm,” the survey said.

The Pew survey found that 24% of online teens now use Twitter, up from 16% in 2011. Other social platforms such as Tumblr, Instagram (which is owned by Facebook), YouTube and Snapchat also have seen big growth among young users in the past year.

“Those teens who used sites like Twitter and Instagram reported feeling like they could better express themselves on these platforms, where they felt freed from the social expectations and constraints of Facebook,” the Pew survey said. “Nevertheless, the site is still where a large amount of socializing takes place, and teens feel they need to stay on Facebook in order to not miss out.”

Facebook has 1.1 billion users worldwide and remains the most popular social network among U.S. teens.

A Facebook spokesperson declined to comment specifically Wednesday on the Pew report but pointed to statements by CFO David Ebersman in a recent conference call about quarterly earnings, in which he emphasized Facebook’s popularity among users under 25.

“We continue to have really high penetration rates among that age group, both in the U.S. and globally, and … younger users remain among the most active and engaged users,” Ebersman said. “Younger users are extremely active users of Instagram as well.”

Facebook executives maintain that teen use of their social network has remained steady. They argue that Facebook is not losing users to other platforms — instead, they say, more users are visiting other social media sites in addition to Facebook.

“The urban legend (that Facebook is losing younger users) flows more often than not from surveys people have done of younger users that indicate that they’re using other social services … much of the concern stems from the assumption that this is a zero-sum game, and that’s not how we see it,” Ebersman said. “We think the overall amount of time spent on services that enable you to connect and share is growing and will continue to grow.”

Jeff Hancock, a professor of communication at Cornell University and a frequent social media analyst, mostly agrees.

“Facebook’s attraction to youth is based in part on being connected, but also on being an ‘ingroup’ and ‘cool’ thing. To the degree that the cool of Facebook wears off, we should see some migration of teens to other platforms,” he said.

“People are unlikely to fully leave Facebook but simply to diversify their tools for accomplishing social interaction. Instead of Facebook being the Walmart of social media, it will become just one platform in a big ecology, including photo sharing with Instragram, broadcasting with Twitter, etc.”

Pew’s findings are based on a nationally representative phone survey, run by its Internet American Life Project, of 802 teens ages 12-17. It was conducted between July 26 and September 30, 2012. Pew also conducted two online focus groups of teenagers ages 12-17 in June 2012.

Pew found that the typical (median) teen Facebook user has 300 friends, while the typical teen Twitter user has 79 followers.

OtterBox acquires rival LifeProof


The popular LifeProof case joins the OtterBox family.

If you can’t beat ‘em, buy ‘em.

OtterBox, which struggled for months to bring a waterproof iPhone case to market, has acquired rival LifeProof, which makes one of the best — and best-selling — tough iPhone cases.

Colorado-based OtterBox has been a leading case manufacturer for a variety of smartphones and
tablets and has quickly grown to employ 650 people worldwide. LifeProof, based in San Diego and founded in 2009 by Australian Gary Rayner, employees 250 people.

OtterBox says those 250 employees are now “members of the OtterBox family and will remain in their San Diego location for the foreseeable future.” Over the next 30 days, OtterBox will begin incorporating the LifeProof brand into that OtterBox family.

LifeProof just unveiled a waterproof
iPad Mini case at the CTIA trade show in Las Vegas (it’s expected to ship in June for $99.99), and a LifeProof case for the
Samsung Galaxy S4 is expected to ship by mid summer.

Terms of the deal weren’t disclosed, but it was likely in the tens of millions of dollars and perhaps even more. In 2012, OtterBox had approximately $600 million in revenues. That was up from $10.8 million in 2008.

Yes, the iPhone-case game is big business.

Amazon proposes a colossal biospherelike Seattle campus

Amazon’s proposed design for its new Seattle campus.


(Credit:
NBBJ)

The latest fad for tech companies’ new office buildings seems to involve making them as far-out and avant-garde as possible. And Amazon is the newest firm to jump on that train.

The e-commerce giant and gadget maker unveiled a slew of new drawings (PDF) on Tuesday that reveal a series of colossal, mirrored, biospherelike domes alongside a taller rectangular building that could be its new campus. The designs were created by architecture firm NBBJ and also include a copious amount of green space and landscaping.

The intent behind the design, according to the project proposal (PDF), is to “create an alternative environment” where “employees can work and socialize in a more natural, parklike setting.”

“The generative idea is that a plant-rich environment has many positive qualities that are not often found in a typical office setting,” the proposal says. “While the form of the building will be visually reminiscent of a greenhouse or conservatory, plant material will be selected for its ability to co-exist in a microclimate that also suits people.”

According to the proposal, the offices will have in-house dining, meeting, and lounge spaces, as well as a “a variety of botanical zones modeled on…ecologies found around the globe.” In all, the designs for the campus include 3.3 million square feet of office space, with three 37-story office towers. The three massive spheres will range from 80 to 95 feet high.

Amazon has been planning to expand its offices for a while. The company plunked down $1.16 billion for 1.8 million square feet of new office space in Seattle last October. The design proposal for its new campus is to be discussed Tuesday evening at a Design Review Board meeting at Seattle’s City Hall.

While Amazon’s design is unconventional, to say the least, the company is one of several tech firms to have proposed such futuristic and nature-friendly office buildings as of late. Apple is working on getting designs for a low-level, circular, spaceshiplike headquarters approved in Cupertino, Calif.; and Facebook is in the process of breaking ground on its swanky second campus in Menlo Park, Calif., which is a long, narrow, rooftop-gardened building designed by renowned architect Frank Gehry.

Here are some more images of the proposed design for Amazon’s campus:

NASA funds attempt at 3D food printer for pizza

3D food printer schematic

This schematic shows how the 3D food printer would function.

Systems and Materials Research)

“Star Trek” food replicators will always be the holy grail of space-snack technology, but we could be edging a step closer to the dream thanks to the work of mechanical engineer Anjan Contractor with Systems and Materials Research in Austin, Texas.

Systems and Materials Research recently received a $125,000 grant from NASA to make a pizza. OK, it’s a little more complicated than that. Contractor already created a proof-of-concept printer that can print chocolate onto a cookie. His next goal is to print out dough and cook it while printing out sauce and toppings.

Contractor isn’t just planning to use cartridges full of red sauce, but rather the building blocks of food products. Cartridges full of powders and oils could be combined to make different foods. These cartridges would have extremely long shelf lives, making them appropriate for feeding astronauts during long-distance space travel.

“The way we are working on it is, all the carbs, proteins and macro and micro nutrients are in powder form. We take moisture out, and in that form it will last maybe 30 years,” Contractor told news site Quartz in an article posted Tuesday.

This doesn’t sound like a sublime foodie experience, but it could be a practical way to keep people fed all the way to Mars. It could also offer a lot more variety than the usual freeze-dried fare. Five months into your trip to Mars, I bet a hot 3D-printed pizza with a mystery protein layer would taste pretty dang good.

Contractor is starting work on building the prototype pizza printer. In case you’re hungry right now, you can check out his chocolate printer below.

Injustice: Gods Among Us Review

Injustice: Gods Among Us Review

Publisher: Warner Bros
Developer: NetherRealm Studios
UK Price: £33
US Price: $50

Superman is a boring character to root for in his own stories because he’s the epitome of limitless ability. You can’t feel scared he might not succeed or believe he’s an underdog against anyone as he’s near-enough perfect. You’ll pick up a book with him in it and everything will go great and maybe there’ll be some kryptonite thrown around as a minor obstacle but it’s more than obvious things will come up aces; that doesn’t make for a compelling romp and it sure means that most of his narratives are just ways of reframing older versions of tales that have already occurred.

Injustice: Gods Among Us Review

The best Superman stories are about the ramifications of him existing rather than his personal actions. Injustice: Gods Among Us, DC’s newest entry into fighting games developed by Mortal Kombat designers NetherRealm, takes cues from a variety of stories that paint Superman as the villain. Here Superman is distraught over The Joker tricking him into destroying his home city of Metropolis, housing his wife and unborn child at the time. He mercilessly kills the Clown Prince in revenge and begins setting up a despotic rule in order to keep everyone safe from any further harm. Many other superheroes join in with this attempt at total domination through either believing that Superman is correct or under threat of death. Those that refuse and are still alive band together to create a resistance faction that solicits the aid of alternate universe heroes from a world where The Joker’s plot wasn’t successful.

NetherRealm excel at story modes above those of other fighting game developers. Their work does more than make vague justifications as to why two characters are fighting as has become the standard. Injustice is carrying over what they’ve learned from the previous Mortal Kombat, about cutscenes transitioning into action and picking right back up when the fight resolves. This achieves a great many things like answering why characters can possibly be fighting alternately costumed versions of themselves and even clearing away how those with limited powers could stand up against those with far greater abilities and win.

The story is a little hokey in areas, but no more so than the properties it’s based on. We’re lead to believe that Alternate Superman is an awful tyrant ostensibly enslaving the world’s population without really any depictions of this actually happening, but small holes like that are forgiveable in a narrative that manages to believably give villain mainstays motivation to work with heroes on the side of good, rotates the playable cast enough – and at the right times to prevent boredom – and makes Aquaman actually seem like a badass.

(CNN) — On Wednesday, NASA officials announced a serious problem with the Kepler satellite, the world’s most successful planet-finding machine.

Since its launch four years ago, Kepler has found more than 2,700 possible planets orbiting stars other than our Sun, of which more than 100 have been confirmed. A few of these exoplanets resemble the Earth in size or mass.

Recently, three Earth-like planets were even reported to be in the habitable zone: close enough to the star they orbit that water is liquid, yet not so close that it is boiling. Planets with liquid water may well harbor life.

Now, the second of four of the Kepler spacecraft’s reaction wheels, which aim the vessel’s instruments, appears to have failed. It remains to be seen whether full repairs are possible.

For the spacecraft to point accurately, at least three reaction wheels are needed, corresponding to the three dimensions (up-down, north-south, east-west). The fourth wheel serves as a backup and provides cross-comparisons of data among the wheels. The first wheel failed last summer; now Kepler has too few reaction wheels to keep pointing with sufficient stability.

When a major component like a thruster fails on any spacecraft, operations software points the craft’s solar panels toward the sun to ensure a continuous power supply.

Power is a satellite’s lifeblood: Lose it and you lose communications, so the satellite can’t be oriented properly or take data. Backup batteries allow the solar panels to be misdirected for a few hours or so, before all power is lost. But batteries drain quickly, so engineers design software to make sure that when something goes wrong, the spacecraft points in a direction that preserves power.

Urry: Three more homes for life in the universe?

Reaction wheels are spinning flywheels that carry “angular momentum,” a term roughly analogous to the force that keeps a car coasting even when the driver’s foot is off the gas.

Spinning objects keep spinning unless they transfer angular momentum to another object. For example, if a flywheel is commanded to spin more slowly (through an electric motor), the spacecraft will pick up spin to compensate. If the flywheel spins faster, the spacecraft will spin in the opposite direction. Increasing or decreasing the spin of a reaction wheel is therefore a way of pointing the spacecraft.

This may sound like a complicated way to make a telescope move, but the problem is, there is nothing in empty space to push on. To close a door, you push on it. This works because gravity holds you firmly on the ground, and your feet stay put because of friction with the floor.

If you pushed on an open door in space, it would push you in the opposite direction. In space, there is no standing still. So Kepler’s reaction wheels are essential for pointing the spacecraft accurately and steadily.

Unfortunately, less stable pointing means less accurate photometry (the measurement of light from the star). Since Kepler finds planets by measuring the tiny dips in a star’s brightness when a dark planet moves across the face of that star, less accurate photometry means Earth-like planets will be too hard to find.

Urry: A meteor and asteroid — 1 in 100 million odds

NASA is trying to figure how to fix or work around the broken reaction wheels. It has done amazing things before; you don’t have to be an optimist to think there is still a chance to turn Kepler around.

But the loss of a fully functional Kepler would be terrible. It has found more potential planets than any other facility or method. Kepler data have yielded an estimate of the total number of Earth-like planets in the Milky Way galaxy: at least 17 billion. That’s an Earth-like planet around one in every six stars.

Fortunately, there are other ways to find planets than by detecting transits (the passage of a planetary body across a sun), as Kepler does. In fact, the first few hundred exoplanets were found by the “radial velocity” technique, which detects tiny motions of a star as it and its planets orbit one another.

A Yale astronomy professor, Debra Fischer, has pioneered clever improvements to this technique so that she can find 100 Earth-size planets, perhaps 10% of which might harbor life. (Hear the full story in Fischer’s TEDx talk, “Why We Need to Find 100 Earths.”)

Fischer is going after Earth-like planets in the habitable zone. After all, the discovery of life on another planet would cause a profound shift in our world view, akin to the Copernican shift from an Earth-centric to a Sun-centric world.

So when Fischer says we should be “the alien civilizations that explore other worlds,” I say: With Kepler or without, it’s only a matter of time until we find signs of life on other worlds.
