Mood-sensing smartphone tells your shrink how you feel

PEOPLE with anxiety, depression or stress are often asked to record their mood changes throughout the day, helping psychologists fine-tune their treatment. But they often forget, recording only sparse information at best. Now an emotion-sensing smartphone app that automatically generates someone's "mood diary" could give psychologists all the data they need.

It's the brainchild of Matt Dobson and Duncan Barclay, founders of speech recognition firm EI Technologies, based in Saffron Walden, UK. Instead of relying on people writing diaries, the app, called Xpression, listens for telltale changes in a person's voice that indicate whether they are in one of five emotional states: calm, happy, sad, angry or anxious/frightened. It then lists a person's moods against the times they change, and automatically emails the list to their psychologist at the end of the day.

To work, the app has to be always on, listening out for the user's voice once every second, whether they are talking to family, friends, colleagues or even pets. It also listens in on phone calls. If the user is silent, the app does nothing. Crucially for the users' privacy, it doesn't record their words, instead seeking out telltale acoustic features – like pitch – that are indicative of emotional state.

This kind of emotion recognition via voice pattern already works well and is a "hot area" of research, says Stephen Cox, head of the speech processing lab at the University of East Anglia in Norwich, UK, who is scientific adviser for the firm.

Initially, Xpression will send 200-millisecond-long acoustic snapshots to a remote server where a machine-learning system will work out a person's emotional state before sending it back to the app for storage. Factors like voice loudness, intensity, changes in pitch and speaking pace allow the system to accurately estimate somebody's emotional state. "We extract acoustic features and let the machine-learning system work it out," says Cox. This ability will be built into the app itself eventually, says Dobson.

There's a strong need for this kind of technology, says Adrian Skinner, a clinical psychologist with the UK's National Health Service in Harrogate, North Yorkshire. "With conditions like depression, people tend to stop doing things like filling in mood diaries. If this app gives us more complete diaries it could help us better find the day-to-day triggers that raise or lower a patient's mood," he says.

The firm is a finalist in a UK government competition to identify the nation's top mobile tech company, to be judged on 26 February. An insurance company has already expressed an interest in using the app to ensure the workplace stress therapy it pays for is effective. Clinical trials are due to take place later this year.

Uncertainty hangs heavy as Italy braces for elections

ROME: Italy was poised to hold its most important elections in a generation starting on Sunday, as financial markets warned an unclear outcome could plunge the eurozone's third economy back into crisis.

Italians will cast their ballots as they grapple with the longest recession in two decades and several rounds of austerity cuts that have caused deep resentment and could favour a low turnout and a high number of protest votes.

The most likely outcome is a centre-left government led by Democratic Party leader Pier Luigi Bersani, a cigar-chomping former communist with a down-to-earth manner who now espouses broadly pro-market economic views.

But the result is by no means certain and whether Bersani will be able to form a stable coalition is in doubt. Some fear there may have to be another election within months after a reform of a maddeningly complex electoral law.

With everything at stake, the campaign has been remarkably underwhelming, with few rallies and a lot of back-and-forth in television interviews that have provided little or no detail on sometimes extravagant programme promises.

A case in point was Silvio Berlusconi's promise to refund Italians an unpopular property tax levied by Prime Minister Mario Monti's government in a letter that prompted some to queue up to claim their money back immediately.

European capitals and foreign investors will be watching closely as a return to Italy's free-wheeling public finances could spell disaster for the eurozone.

"We believe that a risk exists that after the February 24-25 elections there may be a loss of momentum on important reforms to improve Italian growth prospects," Standard & Poor's ratings agency said in a report this week.

London-based Capital Economics warned that even with a stable governing majority "huge underlying economic problems suggest that it may only be a matter of time before concerns about the public finances begin to build again."

"And a hung parliament might plunge Italy and the eurozone back into crisis rather sooner," the independent economic research company said this week.

Polls open at 0700 GMT on Sunday and close at 1900 GMT. A second day of voting on Monday begins at 0600 GMT and ends at 1400 GMT, after which preliminary results will begin to trickle through late Monday and into Tuesday.

Wild card

The wild card in the election will be Beppe Grillo, a tousle-haired former comedian whose mix of invective and idealism appeals to protest voters fed up with corrupt politicians. He has spoken to packed squares across Italy.

Bersani has said he will follow the course set by Monti, a former high-flying European commissioner roped in to replace the scandal-tainted Berlusconi who was forced to step down in November 2011.

But Bersani will come under immediate pressure to row back on austerity and do more to create jobs in an economy where an already record-high unemployment rate of 11.2 per cent masks far higher joblessness among women and young people.

A Bersani victory is far from a sure thing mainly because of the rapid rise in the polls of Berlusconi, the irrepressible 76-year-old billionaire tycoon who is still in the game even after 20 tumultuous years in Italian politics.

This is the sixth election campaign for Berlusconi, who has been prime minister three times, has survived multiple court cases, sex scandals and diplomatic gaffes.

One recent poll said he was within 2.5 points of catching up with Bersani.

Berlusconi has pursued a populist campaign, intimating that Italy's current social misery can be blamed on a "hegemonic" Germany imposing austerity.

The president of the European Parliament, who was once invited to play the role of a Nazi camp guard by Berlusconi during a speech when he was still prime minister, has warned Italians not to vote for the flamboyant tycoon.

"Berlusconi has already sent Italy into a tailspin with irresponsible government action and personal capers," Martin Schulz told German tabloid Bild, adding that Italy should not lose its new found confidence in Europe.

Several polls indicate that Bersani may score only a half-victory by managing to secure a stable majority in the lower house of parliament, the Chamber of Deputies, but failing to get one in the upper house, the Senate.

That would give Monti, a somewhat staid economics professor who is running as head of an eclectic centrist grouping, a crucial role as a coalition partner and could bring him back into a government with a ministerial posting.

An average of the most recent polls, which cannot be published in the two weeks leading up to the election, would give Bersani 34 per cent, Berlusconi 30 per cent, Grillo 17 per cent and Monti between 10 and 12 per cent of the vote.

Coming after the last polls were made public, Pope Benedict XVI's resignation could boost the church-going Monti and stop Berlusconi as it has drawn away the media attention that the showman tycoon has often relied on.

The run-up to the vote has also been marked by a succession of high-profile corruption inquiries against politicians and business leaders in a period similar to one in the early 1990s that brought down an entire political class.

Monti has said that the storm of scandals marks "the end of an era".

Social media aggregator Memolane to shut down

Memolane's timeline service.

(Credit:
Eddie Echo/CNET)

Memolane, a social media aggregator that promised trips down memory lane, announced today it is shutting down immediately and will delete users' account content tomorrow.

Launched in 2010, the Web app extracted each moment users shared on popular social-networking services such as Facebook, Last.fm, Twitter, Foursquare, and others and combined them into one visual timeline. Posts/comments/tweets/etc. were organized by their respective dates and posted as memos under each date.

The San Francisco-based company had raised $2.5 million in venture capital but announced today in a company blog post that it is joining another company that it did not identify that would "utilize the Memolane features in an expanded way, adding more value to all the great memories captured on social media."

Our goal was to make it exciting to relive great adventures with friends. We are proud that we could bring joy to people's lives by sending out daily emails with fun memories from the past. As well, it has been a thrill to share in the excitement when one of our fans rediscovers a precious moment that was once lost.

It wasn't immediately clear if Memolane had been acquired by another company, and if so, who that company might be. But Memolane said the "merger" means that all accounts and their contents would be deleted Friday but noted that the content would still be available at users' original social media sources.

The company also suggested users try formerly competing services offered by Timehop and Jolicloud.

CNET has contacted Memolane for more information and will update this report when we learn more.

Oldest Known Wild Bird Hatches Chick at 62

Wisdom, the oldest known wild bird, has yet another feather in her cap—a new chick.

The Laysan albatross (Phoebastria immutabilis)—62 years old at least—recently hatched a healthy baby in the U.S. Midway Atoll National Wildlife Refuge, her sixth in a row and possibly the 35th of her lifetime, according to the U.S. Geological Survey's (USGS) North American Bird Banding Program. (Related: "51-Year-Old Albatross Breaks N. American Age Record [2003].")

But Wisdom's longevity would be unknown if it weren't for a longtime bird-banding project founded by USGS research wildlife biologist Chandler Robbins.

Now 94, Robbins was the first scientist to band Wisdom in 1956, who at the time was "just another nesting bird," he said. Over the next ten years, Robbins banded tens of thousands of black-footed albatrosses (Phoebastria nigripes) and Laysan albatrosses as part of a project to study the behavior of the large seabirds, which at the time were colliding with U.S. Navy aircraft.

Robbins didn't return to the tiny Pacific island—now part of the U.S. Papahānaumokuākea Marine National Monument—until 2002, when he "recaptured as many birds as I could in hopes that some of them would be the old-timers."

Indeed, Robbins did recapture Wisdom—but he didn't know it until he got back to his office at the Patuxent Wildlife Research Center in Laurel, Maryland, and checked her band number in the database.

"That was real exciting, because we didn't think the chances of finding one that old would be that good," Robbins said Wednesday in an interview from his office at the Patuxent center, where he still works.

Albatrosses No Bird Brains

Bigger birds such as the albatross generally live longer than smaller ones: The oldest bird in the Guinness Book of Animal Records, a Siberian white crane (Leucogeranus leucogeranus), lived an unconfirmed 82 years. Captive parrots are known to live into their 80s. (See National Geographic's bird pictures.)

The Laysan albatross spends most of the year at sea, nesting on the Midway Atoll (map) in the colder months. Birds start nesting around five years of age, which is how scientists knew that Wisdom was at least five years old in 1956.

Because albatrosses defend their nests, banding them doesn't require a net or a trap as in the case of other bird species, Robbins said—but they're far from tame.

"They've got a long, sharp bill and long, sharp claws—they could do a job on you if you're not careful how to handle them," said Robbins, who estimates he's banded a hundred thousand birds.

For instance, "when you're not looking, the black-footed albatross will sneak up from behind and bite you in the seat of the pants."

But Robbins has a fondness for albatrosses, and Wisdom in particular, especially considering the new dangers that these birds face.

Navy planes are no longer a problem—albatross nesting dunes were moved farther from the runway—but the birds can ingest floating bits of plastic that now inundate parts of the Pacific, get hooked in longlines meant for fish, and be poisoned by lead paint that's still on some of Midway Atoll's buildings. (Also see "Birds in 'Big Trouble' Due to Drugs, Fishing, More.")

That Wisdom survived so many years avoiding all those hazards and is still raising young is quite extraordinary, Robbins said.

"Those birds have a tremendous amount of knowledge in their little skulls."

"Simply Incredible"

Wisdom's accomplishments have caught the attention of other scientists, in particular Sylvia Earle, an oceanographer and National Geographic Explorer in Residence, who said by email that Wisdom is a "symbol of hope for the ocean." (National Geographic News is part of the National Geographic Society.)

Earle visited Wisdom at her nest in January 2012, where she "appeared serenely indifferent to our presence," Earle wrote in the fall 2012 issue of the Virginia Quarterly Review.

"I marveled at the perils she had survived during six decades, including the first ten or so years before she found a lifetime mate. She learned to fly and navigate over thousands of miles to secure enough small fish and squid to sustain herself, and every other year or so, find her way back to the tiny island and small patch of grass where a voraciously hungry chick waited for special delivery meals."

Indeed, Wisdom has logged an estimated two to three million miles since 1956—or four to six trips from Earth to the moon and back, according to the USGS. (Related: "Albatross's Effortless Flight Decoded—May Influence Future Planes.")

Bruce Peterjohn, chief of the North American Bird Banding Program, called Wisdom's story "simply incredible."

"If she were human, she would be eligible for Medicare in a couple years—yet she is still regularly raising young and annually circumnavigating the Pacific Ocean," he said in a statement.

Bird's-Eye View

As for Robbins, he said he'd "love to get out to Midway again." But in the meantime, he's busy going through thousands of bird records in an effort to trace their life histories.

There's much more to learn: For instance, no one has ever succeeded in putting a radio transmitter on an albatross to follow it throughout its entire life-span, Robbins noted.

"It would be [an] exciting project for someone to undertake, but I'm 94 years old," he said, chuckling. "It wouldn't do much for me to start a project at my age."

Arias Challenged On Pedophilia Claim

Accused murderer Jodi Arias was challenged today by phone records, text message records, and her own diary entries that appeared to contradict her claim that she caught her ex-boyfriend, Travis Alexander, looking at pictures of naked boys.

Arias had said during her testimony that one afternoon in January 2008, she walked in on Alexander masturbating to pictures of naked boys. She said she fled from the home, threw up, drove around aimlessly, and ignored numerous phone calls from Alexander because she was so upset at what she had seen.

The claim was central to the defense's accusation that Alexander was a "sexual deviant" who grew angry and abusive toward Arias in the months after the incident, culminating in a violent confrontation in June that left Alexander dead.

Arias claimed she killed him in self-defense. She could face the death penalty if convicted of murder.

Catching Up on the Trial? Check Out ABC News' Jodi Arias Trial Coverage

Today, prosecutor Juan Martinez, who has been aggressive in questioning witnesses throughout the trial, volleyed questions at her about the claim of pedophilia, asking her to explain why her and Alexander's cell phone records showed five calls back and forth between the pair throughout the day she allegedly fled in horror. Some of the calls were often initiated Arias, according to phone records.

She and Alexander also exchanged text messages throughout the afternoon and evening at a time when Arias claims the pedophilia incident occurred. In those messages they discuss logistics of exchanging one another's cars that night. Alexander sends her text messages about the car from a church social event he attended that night that she never mentioned during her testimony.

Arias stuck by her claim that she saw Alexander masturbating to the pictures, and her voice remained steady under increasingly-loud questioning by Martinez.

But Martinez also sparred with Arias on the stand over minor issues, such as when he asked Arias detailed questions about the timing and order of events from that day and Arias said she could not remember them.

"It seems you have problems with your memory. Is this a longstanding thing? Since you started testifying?" Martinez asked.

"No it goes back farther than that. I don't know even know if I'd call it a problem," Arias said.

"How far back does it go? You don't want to call them problems, are they issues? Can we call them issues? When did you start having them?" he asked in rapid succession. "You say you have memory problems, that it depends on the circumstance. Give me the factors that influence that."

"Usually when men like you or Travis are screaming at me," Arias shot back from the stand. "It affects my brain, it makes my brain scramble."

"You're saying it's Mr. Martinez's fault?" Martinez asked, referring to himself in the third person.

"Objection your honor," Arias' attorney finally shouted. "This is a stunt!"

Timeline of the Jodi Arias Trial

Martinez dwelled at one point about a journal entry where Arias wrote that she missed the Mormon baptism of her friend Lonnie because she was having kinky sex with Alexander. He drew attention to prior testimony that she and Alexander used Tootsie Pops and Pop Rocks candy as sexual props.

"You're trying to get across (in the diary entry) that this involved a sexual liaison with Mr. Alexander right?" he asked. "And you're talking about Tootsie Pops and Pop Rocks?"

"That happened also that night," Arias said.

"You were there, enjoying it, the Tootsie Pops and Pop Rocks?" he asked again, prompting a smirk from Arias.

"I enjoyed his attention," Arias said.

Higgs may spell doom, unless supersymmetry saves us

Lisa Grossman, physical sciences reporter

(Image: CERN)

Is the Higgs boson a herald of the apocalypse? That's the suggestion behind a theory, developed more than 30 years ago, that is back in the headlines this week. According to physicists, the mass of the Higgs-like particle announced last summer supports the notion that our universe is teetering on the edge of stability, like a pencil balanced on its point.

"It may be that the universe we live in is inherently unstable," Joseph Lykken, of the Fermi National Accelerator Laboratory in Batavia, Illinois, said on Monday at a meeting of the American Association for the Advancement of Science. "At some point, billions of years from now, it's all going to be wiped out."

Physicists have been wringing their hands about this scenario since 1982, when theorists Michael Turner and Frank Wilczek published a paper about it in Nature, NBC News points out. The pair showed that the vacuum of space can be in different energy states, and it will be most stable at its lowest energy. Trouble arises if we're not there yet, and we're inhabiting a temporarily stable state that should ultimately collapse.

"The universe wants to be in a different state, so eventually to realize that, a little bubble of what you might think of as an alternate universe will appear somewhere, and it will spread out and destroy us," Lykken said at AAAS.

Enter the Higgs boson, the particle form of the field that gives mass to several fundamental particles. The Higgs field permeates the vacuum of space, which means the mass of the boson and the stability of the vacuum are closely intertwined. Theory predicted that if the Higgs boson is heavier than about 129 gigaelectronvolts (GeV), the universe should be on safe footing.

But in July 2012 physicists at CERN, near Geneva, Switzerland announced that a particle closely matching the Higgs had been found by experiments in the Large Hadron Collider (LHC). The much celebrated particle has a mass of about 126 GeV - light enough to raise fears of instability.

There is still hope for the universe as we know it. Some theorists pointed out that the relationship between the Higgs mass and the vacuum of space depends on the mass of a particle called the top quark. If the top quark's mass is different than we think it is, stability might reign.

There are also anomalies with the Higgs measurement, like the fact that it decays into photons more often than predicted. That hints we may yet find particles from the theory of supersymmetry, which says each ordinary particle has heavier "superpartners". If the Higgs has such a relative, it might save us from destruction. But some of these predicted particles, particularly the superpartners of the top quark, can push the universe back into instability.

The worries may remain unconfirmed for a while. The LHC is shutting down for a two-year break so engineers can prepare the machine to shoot higher-energy particle beams, which are needed to probe for superpartners.

Sony bills coming PS4 console as future of gaming

NEW YORK: Sony unveiled a new-generation PlayStation 4 (PS4) system on Wednesday and laid out its vision for the "future of gaming" in a world rich with mobile gadgets and play streamed from the Internet cloud.

At a press event in New York, computer entertainment unit chief Andrew House said PS4 "represents a significant shift from thinking of PlayStation as a box or console to thinking of the PlayStation 4 as a leading place for play."

PS4 was designed to get to know players, ideally to the point of being able to predict which games people will buy and have them pre-loaded and ready to go.

It also allows live streaming of gameplay in real-time, letting friends virtually peer over one another's shoulders and even letting game makers to act as "directors" guiding players along.

Sony has also given a "green light" to building "the most powerful network for gaming in the world", according to David Perry, chief of Gaikai cloud gaming company purchased last year by Sony.

Gaikai specialises in letting people play video games streamed from the Internet "cloud" instead of buying titles on disks popped into consoles or computers.

"By combining PlayStation 4, PlayStation Network and social platforms, our vision is to create the first social network with meaning dedicated to games," Perry said during the event.

A button on the PS4 controller will let players instantly stream in-game action to friends in real time, and even allow someone to transfer control to more capable allies when stuck, according to Perry.

He expressed a vision of letting people access and play video games old or new on the Internet using PS4, smartphones, tablets or PS Vita handheld devices.

"We are exploring opportunity enabled by cloud technology with a long-term vision of making PlayStation technology available on any device," Perry said.

"This would fundamentally change the concept of game longevity, making any game new or old available to get up and running on any device, anywhere."

Sony needs to adapt to changing lifestyles while not alienating video game lovers devoted to its hardware.

Low-cost or free games on smartphones or tablet computers are increasing the pressure on video game companies to deliver experiences worth players' time and money.

With the press event still in progress, Sony had yet to indicate availability or pricing for the PS4. New-generation consoles are typically priced in the $400 to $500 range, and blockbuster game titles hit the market at $60 each.

Sony mum on PlayStation Vita price drops for U.S., Europe

Sony breathed new life into its PlayStation Vita portable alongside the introduction of the PlayStation 4 today.

The gist of the news: The Vita can be used as a full screen and controller for your PS4, similar to what Nintendo's done with the
Wii U. The idea is that you can continue to play a game on the PS4 through your Vita, even if someone needs to use the TV for something else. The only catch for now is that the two devices need to be on the same Wi-Fi network.

That should make the handheld gaming device more attractive to would-be buyers who are looking for more utility from the $249 or $299 entry price, and who plan on buying Sony's upcoming console.

But smart buyers know a price drop is coming, something that could stall already tepid sales. Earlier this week Sony announced plans to cut the price of the Vita in Japan, bringing both the Wi-Fi and 3G models down to the same price in an effort to boost sales. In the past, those types of price cuts have trickled down to other markets, and such an announcement was anticipated by some today.

Since its launch in in early 2012, sales of the Vita have proven to be lackluster compared to Sony's predecessor, the PSP. In a recent interview with Famitsu magazine, Sony Computer Entertainment Japan president Hiroshi Kawano admitted that the portable gaming system still has "a ways to go," and that it was "a little behind the numbers we originally pictured," adding that the price cut was intended to make the device more accessible.

While much of the attention during today's press conference was on the PlayStation 4 -- which was not shown on stage, or given a price or release date beyond "Holiday 2013" -- the Vita got some attention. To show off the new remote play feature, the company demoed Knack, an upcoming title for the PS4 that uses streaming technology Sony acquired from Gaikai.

Sony Computer Entertainment president and group CEO Andrew House today also stressed the company's "unwavering commitment to phenomenal play experience," that would "continue to unlock the PlayStation Vita's potential." That would come in additional features arriving later this year, House teased, but he did not provide specifics.

NASA's Mars Rover Makes Successful First Drill

For the first time ever, people have drilled into a rock on Mars, collecting the powdered remains from the hole for analysis.

Images sent back from NASA's Mars rover Curiosity on Wednesday confirmed that the precious sample is being held by the rover's scoop, and will soon be delivered to two miniature chemical labs to undergo an unprecedented analysis. (Related: "Mars Rover Curiosity Completes First Full Drill.")

To the delight of the scientists, the rock powder has come up gray and not the ubiquitous red of the dust that covers the planet. The gray rock, they believe, holds a lot of potential to glean information about conditions on an early Mars. (See more Mars pictures.)

"We're drilling into rock that's a time capsule, rocks that are potentially ancient," said sampling-system scientist Joel Hurowitz during a teleconference from NASA's Jet Propulsion Laboratory in California.

A Place to Drill

The site features flat bedrock, often segmented into squares, with soil between the sections and many round gray nodules and white mineral veins.

Hurowitz said that the team did not attempt to drill into the minerals or the gray balls, but the nodules are so common that they likely hit some as they drilled down 2.5 inches (6.3 centimeters).

In keeping with the hypothesis that the area was once under water, Hurowitz said the sample "has the potential of telling us about multiple interactions of water and rock."

The drill, located at the end of a seven-foot (two-meter) arm, requires precision maneuvering in its placement and movement, and so its successful initial use was an exciting and welcome relief. The rover has been on Mars since August, and it took six months to find the right spot for that first drill. (Watch video of the Mars rover Curiosity.)

The flat drilling area is in the lower section of Yellowknife Bay, which Curiosity has been exploring for more than a month. What was previously identified by Curiosity scientists as the dry bed of a once-flowing river or stream appears to fan out into the Yellowknife area.

The bedrock of the site—named after deceased Curiosity deputy project manager John Klein—is believed to be siltstone or mudstone. Scientists said the veins of white minerals are probably calcium sulfate or gypsum, but the grey nodules remain something of a mystery.

Triumph

To the team that designed and operates the drill, the results were a triumph, as great as the much-heralded landing of Curiosity on the red planet. With more than a hundred maneuvers in its repertoire, the drill is unique in its capabilities and complexities. (Watch video of Curiosity's "Seven Minutes of Terror.")

Sample system chief engineer Louise Jandura, who has worked on the drill for eight years, said the Curosity team had made eight different drills before settling on the one now on the rover. The team tested each drill by boring 1,200 holes on 20 types of rock on Earth.

She called the successful drilling "historic" because it gives scientists unprecedented access to material that has not been exposed to the intense weathering and radiation processes that affect the Martian surface.

Mini-laboratories

The gray powder will be routed to the two most sophisticated instruments on Curiosity—the Sample Analysis at Mars (SAM) and Chemistry and Mineralogy (CheMin).

SAM, the largest and most complex instrument onboard, operates with two ovens that can heat the sample up to 1,800°F (982°C), turning the elements and compounds in the rock into gases that can then be identified. SAM can also determine whether any carbon-based organic material is present.

Organics are the chemical building blocks of life on Earth. They are known to regularly land on Mars via meteorites and finer material that rains down on all planets.

But researchers suspect the intense radiation on the Martian surface destroys any organics on the surface. Scientists hope that organics within Martian rocks are protected from that radiation.

CheMin shoots an X-ray beam at its sample and can analyze the mineral content of the rock. Minerals provide a durable record of environmental conditions over the eons, including information about possible ingredients and energy sources for life.

Both SAM and CheMin received samples of sandy soil scooped from the nearby Rocknest outcrop in October. SAM identified organic material, but scientists are still trying to determine whether any of it is Martian or the byproduct of organics inadvertently brought to Mars by the rover. (See "Mars Rover Detects Simple Organic Compounds.")

In the next few days, CheMin will be the first to receive samples of the powdered rock, and then SAM. Given the complexity of the analysis, and the track record seen with other samples, it will likely be weeks before results are announced.

The process of drilling and collecting the results was delayed by several glitches that required study and work-arounds. One involved drill software and the other involved a test-bed problem with a sieve that is part of the process of delivering samples to the instruments.

Lead systems engineer Daniel Limonadi said that while there was no indication the sieve on Mars was malfunctioning, they had become more conservative in its use because of the test bed results. (Related: "A 2020 Rover Return to Mars?")

Author of the National Geographic e-book Mars Landing 2012, Marc Kaufman has been a journalist for more than 35 years, including the past 12 as a science and space writer, foreign correspondent, and editor for the Washington Post. He is also author of First Contact: Scientific Breakthroughs in the Hunt for Life Beyond Earth, published in 2011, and has spoken extensively to crowds across the United States and abroad about astrobiology.

Newtown Shooter Had Sensory Processing Disorder

From the time he was little, Adam Lanza couldn't bear to be touched. By middle school, the chaos and noise of large, bustling classrooms began to upset him. At 20, just before the Newtown shootings, he was isolated and, the world would later learn, disturbed.

All this was revealed in "Raising Adam Lanza," an investigative report by the Hartford Courant in partnership with the PBS news program FRONTLINE, which aired Tuesday night.

Before the age of 6, Lanza had been diagnosed with a controversial condition, "sensory integration disorder" -- now known as sensory processing disorder, according to the report.

Those with sensory processing disorder or SPD may over-respond to stimuli and find clothing, physical contact, light, sound or food unbearable. They may also under-respond and feel little or no reaction to pain or extreme hot and cold. A third form involves sensory motor problems that can cause weakness and clumsiness or delay in developing motor skills.

In Photos: Sandy Hook Elementary School Shooting, Mourning

Whether SPD is a distinct disorder or a collection of symptoms pointing to other neurological deficits, most often anxiety or attention-deficit hyperactivity disorder (ADHD), has been debated by the medical community for more than two decades.

No one will know why the withdrawn Lanza shot his mother four times in her own bed, then went to Sandy Hook Elementary School to slaughter six women and 20 first-graders before taking his own life on Dec. 14, 2012.

But this report, the most detailed account to date on his troubled life, paints a picture of a child coping with special needs and a mother, "devoted but perhaps misguided," struggling unsuccessfully to help.

"The most surprising thing for me was this sort of inwardness of Adam, a world view of someone that was afraid of the world," said show producer Frank Koughan. "He just reacted badly to the whole world and didn't want to be part of it. He was not some violent monster, except on one particular day, when he was exceedingly monstrous."

The investigative team interviewed family and friends of the shooter's parents, Nancy and Peter Lanza, and reviewed a decade's worth of messages and emails from his mother to close friends, describing her son's socially awkward behavior.

"Adam was a quiet kid. He never said a word," Marvin LaFontaine, a friend of Nancy Lanza, told them. "There was a weirdness about him and Nancy warned me once at one of the Scout meetings … 'Don't touch Adam.' She said he just can't stand that. He'd become teary-eyed and I think he would run to his mother."

In 1998, the Lanzas left their home in New Hampshire for Connecticut with Adam, who had already been diagnosed with the sensory disorder and was "coded" with an individual education plan, according to a family member who did not want to be identified by FRONTLINE.
