[EX Q]: (CNN) -- Could search crews be just a few hundred feet from solving a mystery that has riveted millions for 76 years? That's the question raised by tantalizing evidence published this week by teams trying to find out what happened to famed aviator Amelia Earhart, who vanished along with navigator Fred Noonan during a doomed attempt to fly around the world in 1937. Yet that evidence has been met with skepticism in some quarters. Debate about the mystery gained new currency this week after researchers publicized images recorded by search teams scanning the ocean floor nearly a year ago near Nikumaroro Island in the South Pacific. The International Group for Historic Aircraft Recovery raised the prospect of a big break in the case by publishing an image online. It showed something -- hard for the layman to size up -- on the ocean floor. The group said, "It's the right size, it's the right shape and it's in the right place." Could it really be a piece of Earhart's Lockheed Electra plane? Louise Foudray, caretaker and historian of the Amelia Earhart Birthplace Museum in Atchison, Kansas, chose her words carefully on Friday afternoon. "We don't want to shrug off the hard work anyone is doing. We do like the idea that people are still interested," she said. "But we're skeptical." Opinion: Will mystery of Earhart be solved? She said there have been other theories that have emerged. One is that Earhart's plane was forced down by the Japanese around the Marshall Islands. Another is that Earhart secretly returned to the United States and the government gave her a new identity. There are people out there who buy those theories. But in reality, Foudray said, "no one has yet to come up with anything conclusive." It wasn't until March that one analyst made a possible connection to Earhart in an online forum for the International Group for Historic Aircraft Recovery. The group said experts have offered various interpretations. Some think the sonar image could be a man-made object, and others say it could be a geologic feature. Earhart: The evidence we almost lost . "So did (last summer's) expedition actually succeed in locating the wreckage of the world's most famous missing airplane? Or is this sonar target just a coral rock or ridge?" the organization says on its website. "Of course we're not going to know until we can get back out there, but until then the anomaly is worth close study." Richard Fredricks, executive director of the American Salvage Association, a trade group, said that "almost anything is possible" these days with advanced technology. And that includes locating a lost airplane. He cited technology such as side-scan sonar and magnetometers but said finding a lost plane such as the Earhart craft is "more a function of funding than technology." Money is needed to invest in expeditions, he said. The International Group for Historic Aircraft Recovery on its website is asking for contributions to continue its work. Foudray said she's heard all of the evidence and nothing solid has risen to the surface. And that includes the latest foray into the South Pacific deep. "We don't expect anything," she said.

[EX Q]: Los Angeles (CNN) -- A medical doctor in Vancouver, British Columbia, said Thursday that California arson suspect Harry Burkhart suffered from severe mental illness in 2010, when she examined him as part of a team of doctors. Dr. Blaga Stancheva, a family physician and specialist in obstetrics, said both Burkhart and his mother, Dorothee, were her patients in Vancouver while both were applying for refugee status in Canada. "I was asked to diagnose and treat Harry to support a claim explaining why he was unable to show up in a small-claims court case," Stancheva told CNN in a phone interview. She declined to cite the case or Burkhart's role in it. Stancheva said she and other doctors including a psychiatrist diagnosed Burkhart with "autism, severe anxiety, post-traumatic stress disorder and depression." The diagnosis was spelled out in a letter she wrote for the small-claims court case, Stancheva said. Stancheva, citing doctor-patient confidentiality, would not elaborate further, nor would she identify the psychiatrist involved in the diagnosis. Burkhart, a 24-year-old German national, has been charged with 37 counts of arson following a string of 52 fires in Los Angeles. The charges are in connection with arson fires at 12 locations scattered through Hollywood, West Hollywood and Sherman Oaks, according to authorities. Stancheva said the refugee applications by Burkhart and his mother were denied by the Canadian government, and she has not seen Burkhart since early March of 2010. "I was shocked and dismayed at what happened in Los Angeles, and it appears he was not being treated for his depression," she said. Burkhart was in court on Wednesday for a preliminary hearing. Prosecutors said his "rage against Americans," triggered by his mother's arrest last week, motivated his "campaign of terror" with dozens of fires in Hollywood and nearby communities. Burkhart kept his eyes closed and remained limp during most of his hearing, requiring sheriff's deputies to hold him up. The district attorney called his courtroom behavior "very bizarre." "This defendant has engaged in a protracted campaign in which he has set, the people believe, upwards of 52 arson fires in what essentially amounts to a campaign of terror against this community," Los Angeles County Deputy District Attorney Sean Carney said. "The people believe he has engaged in this conduct because he has a hatred for Americans." Carney told the court Burkhart would flee the country if he was allowed out of jail on bond, but Los Angeles Superior Court Judge Upinder Kalra said he had no choice but to set bail. To go free while awaiting trial, Burkhart must post a $2.85 million bond and surrender his German passport. It was revealed that Burkhart is also under investigation for arson and fraud in relation to a fire in Neukirchen, near Frankfurt, Germany. The worst arson sprees in the city's history began last Friday morning with a car fire in Hollywood that spread to apartments above a garage, but no new fires have happened since Burkhart was arrested Monday, Los Angeles District Attorney Steve Cooley said. No one was hurt in the fires, but property damage costs are likely to reach $3 million, authorities said. Cooley called it "almost attempted murder," because people were sleeping in apartments above where Burkhart allegedly set cars on fire with incendiary devices placed under their engines. The criminal complaint filed Wednesday also alleged that the fires were "caused by use of a device designed to accelerate the fire," Cooley said. "If found true, the allegation could mean additional custody time for the defendant." "In numerous instances, the cars were parked in carports, resulting in the fires spreading to the adjacent occupied apartment buildings," a sworn affidavit from a Los Angeles arson investigator said. "The vast majority of these fires occurred late at night when the occupants of the apartment buildings were asleep." Investigator Edward Nordskog's affidavit detailed Burkhart's behavior a day before the fires began, when he was in a federal courtroom during extradition proceedings for his mother. "While in the audience, the defendant (Burkhart) began yelling in an angry manner, 'F--k all Americans.' The defendant also attempted to communicate with his mother who was in custody. Shortly thereafter, the defendant was ejected from the courtroom by Deputy U.S. Marshals," Nordskog wrote. Dorothee Burkhart was arrested a day before on an international arrest warrant issued by a district court in Frankfurt, Germany, said federal court spokesman Gunther Meilinger. The 53-year-old German woman is wanted on 16 counts of fraud and three counts of embezzlement, he said. The charges include an allegation that she failed to pay for a breast enhancement operation performed on her in 2004, Meilinger said. Most of the German charges, however, stem from phony real estate deals that Dorothee Burkhart allegedly conducted between 2000 and 2006. "It is my opinion that the defendant's criminal spree was motivated by his rage against Americans and that by setting these fires the defendant intended to harm and terrorize as many residents of the city and county of Los Angeles as possible," Nordskog wrote. A search of Burkhart's Hollywood apartment found newspaper clippings about the Los Angeles fires and articles from Germany reporting similar car fires in Frankfurt, Germany in September, 2011, the investigator said. "It is my opinion based on my experience that it is highly likely the defendant has a history of setting arson fires in Germany before he came to the United States," Nordskog wrote. Burkhart's mother is scheduled for another extradition hearing Friday, while he is due back in court for arraignment on January 24. Meanwhile, both Burkharts are housed in a Los Angeles jail.

[EX Q]: LONDON, England (CNN) -- In the developing world millions of people struggle to operate machinery, read from a blackboard, or just see the world around them, because they don't have access to the eyeglasses they need. Self-refraction glasses let the wearer adjust the lenses to suit their vision, without the need for an optometrist. But a pair of glasses developed by Joshua Silver, a physics professor at the University of Oxford, offers an affordable solution. The glasses can be adjusted to the right strength by the wearer without the need to visit an optometrist. A major reason for that is a chronic shortage of optometrists -- in Ghana, for example, there is just one for every eight million people. That makes it incredibly difficult for ordinary people to visit an optometrist, without which it's impossible for them to get glasses. But Silver thinks he may have come up with a solution to the problem. His self-refraction glasses mean people can correct their vision without needing an optometrist (see Fact Box). "Take a Sub-Saharan country where there is one optometrist for every million people; those people will never see an optometrist, so how will they get eyewear?," he told CNN. "Any model of delivery of vision correction in the developing world that depends on eye care professionals won't work. If you find a model that doesn't rely on them, then you potentially have a solution." Silver has been developing the glasses for over 20 years and continues to research the technology at the Center for Vision in the Developing World (CVDW) at the University of Oxford. He told CNN that about 80 percent of those who try the glasses are able to correct their vision, but there are limitations. They can't be used to correct astigmatism and it's not known if they are suitable for children, although the CVDW is currently running a study to determine if schoolchildren can correct their own vision with their teachers' help. So far, 30,000 pairs of self-refraction glasses have been distributed around the world, through an adult literacy program in Ghana and the U.S. Military Humanitarian and Civic Assistance (HCA) Program. The man behind the HCA program was Kevin White. He has now retired from the military and has set up Global Vision 2020 to distribute self-adjustable glasses. White has just returned from Liberia, where he trained 40 people from local NGOs to dispense the glasses. White sees charity organizations already working in developing countries as the key to distribution. "If I can train people from existing networks to dispense glasses, and they can spare one day each week or month to dispense the glasses, then they can see 50 to 100 people in a day -- and that's a way to reach a lot of people," White told CNN. But for the program to be sustainable, White says the next step is to train his dispensers to become trainers themselves, so that he builds a growing network of people in developing countries who can distribute the glasses. Silver estimates that one billion people in the developing world don't have access to the glasses they need, and he has said that he would like to see all of them wearing glasses by 2020. But he is under no illusions that he can do it alone. "No one person or company can possibly deliver that many glasses by 2020. There's a big infrastructure that needs to be set up to do that, and I'd like to see it happen," he told CNN. Distribution is one problem, cost is another. Currently, it cost $19 to manufacture a pair of self-refraction glasses, and Silver acknowledges that the price needs to come down to a few dollars a pair to make them affordable. Another issue is style. The glasses are currently functional, rather than fashionable, and that may limit their uptake, but more cosmetic versions are being developed. Silver says far more research is needed before those one billion people get their glasses, but he sees his self-refraction technology as a step toward that goal. He told CNN, "It's one of the world's largest problems. There's an immense amount of interest in solving it and self-refraction is one route that can assist with that."
