Bomb suspect influenced by mysterious radical

WASHINGTON (AP) ? In the years before the Boston Marathon bombings, Tamerlan Tsarnaev fell under the influence of a new friend, a Muslim convert who steered the religiously apathetic young man toward a strict strain of Islam, family members said.

Under the tutelage of a friend known to the Tsarnaev family only as Misha, Tamerlan gave up boxing and stopped studying music, his family said. He began opposing the wars in Afghanistan and Iraq. He turned to websites and literature claiming that the CIA was behind the terrorist attacks of Sept. 11, 2001, and Jews controlled the world.

"Somehow, he just took his brain," said Tamerlan's uncle, Ruslan Tsarni, who recalled conversations with Tamerlan's worried father about Misha's influence. Efforts over several days by The Associated Press to identify and interview Misha have been unsuccessful.

Tamerlan's relationship with Misha could be a clue in understanding the motives behind his religious transformation and, ultimately, the attack itself. Two U.S. officials say he had no tie to terrorist groups.

Throughout his religious makeover, Tamerlan maintained a strong influence over his siblings, including Dzhokhar, who investigators say carried out the deadly attack by his older brother's side, killing three and injuring 264 people.

"They all loved Tamerlan. He was the eldest one and he, in many ways, was the role model for his sisters and his brother," said Elmirza Khozhugov, 26, the ex-husband of Tamerlan's sister, Ailina. "You could always hear his younger brother and sisters say, 'Tamerlan said this,' and 'Tamerlan said that.' Dzhokhar loved him. He would do whatever Tamerlan would say.

"Even my ex-wife loved him so much and respected him so much," Khozhugov said. "I'd have arguments with her and if Tamerlan took my side, she would agree: 'OK, if Tamerlan said it.'"

Khozhugov said he was close to Tamerlan when he was married and they kept in touch for a while but drifted apart in the past two years or so. He spoke to the AP from his home in Almaty, Kazakhstan. A family member in the United States provided the contact information.

Tamerlan Tsarnaev was killed in a police shootout Friday. Dzhokhar Tsarnaev was charged Monday with using a weapon of mass destruction to kill, and he could face the death penalty if convicted.

"Of course I was shocked and surprised that he was Suspect No. 1," Khozhugov said, recalling the days after the bombing when the FBI identified Tamerlan as the primary suspect. "But after a few hours of thinking about it, I thought it could be possible that he did it."

Based on preliminary written interviews with Dzhokar in his hospital bed, U.S. officials believe the brothers were motivated by their religious views. It has not been clear, however, what those views were.

As authorities try to piece together that information, they are touching on a question asked after so many terrorist plots: What turns someone into a terrorist?

The brothers emigrated in 2002 or 2003 from Dagestan, a Russian republic that has become an epicenter of the Islamic insurgency that spilled over from the region of Chechnya.

They were raised in a home that followed Sunni Islam, the religion's largest sect. They were not regulars at the mosque and rarely discussed religion, Khozhugov said.

Then, in 2008 or 2009, Tamerlan met Misha, a slightly older, heavyset bald man with a long reddish beard. Khozhugov didn't know where they'd met but believed they attended a Boston-area mosque together. Misha was an Armenian native and a convert to Islam and quickly began influencing his new friend, family members said.

Once, Khozhugov said, Misha came to the family home outside Boston and sat in the kitchen, chatting with Tamerlan for hours.

"Misha was telling him what is Islam, what is good in Islam, what is bad in Islam," said Khozhugov, who said he was present for the conversation. "This is the best religion and that's it. Mohammed said this and Mohammed said that."

The conversation continued until Tamerlan's father, Anzor, came home from work.

"It was late, like midnight," Khozhugov said. "His father comes in and says, 'Why is Misha here so late and still in our house?' He asked it politely. Tamerlan was so much into the conversation he didn't listen."

Khozhugov said Tamerlan's mother, Zubeidat, told him not to worry.

"'Don't interrupt them,'" Khozhugov recalled the mother saying. "'They're talking about religion and good things. Misha is teaching him to be good and nice.'"

As time went on, Tamerlan and his father argued about the young man's new beliefs.

"When Misha would start talking, Tamerlan would stop talking and listen. It upset his father because Tamerlan wouldn't listen to him as much," Khozhugov said. "He would listen to this guy from the mosque who was preaching to him."

Anzor became so concerned that he called his brother, worried about Misha's effects.

"I heard about nobody else but this convert," Tsarni said. "The seed for changing his views was planted right there in Cambridge."

It was not immediately clear whether the FBI has spoken to Misha or was attempting to.

Tsarnaev became an ardent reader of jihadist websites and extremist propaganda, two U.S. officials said. He read Inspire magazine, an English-language online publication produced by al-Qaida's Yemen affiliate.

Tamerlan loved music and, a few years ago, he sent Khozhugov a song he'd composed in English and Russian. He said he was about to start music school.

Six weeks later, the two men spoke on the phone. Khozhugov asked how school was going.

"I quit," Tamerlan said.

"Why did you quit?" Khozhugov asked. "You just started."

"Music is not really supported in Islam," he replied.

"Who told you that?"

"Misha said it's not really good to create music. It's not really good to listen to music," Tamerlan said, according to Khozhugov.

Tamerlan took an interest in Infowars, a conspiracy theory website. Khozhugov said Tamerlan was interested in finding a copy of the book "The Protocols of the Elders of Zion," the classic anti-Semitic hoax, first published in Russia in 1903, that claims a Jewish plot to take over the world.

"He never said he hated America or he hated the Jews," Khozhugov said. "But he was fairly aggressive toward the policies of the U.S. toward countries with Muslim populations. He disliked the wars."

One of the brothers' neighbors, Albrecht Ammon, recently recalled an encounter in which Tamerlan argued about U.S. foreign policy, the wars in Afghanistan and Iraq, and religion.

Ammon said Tamerlan described the Bible as a "cheap copy" of the Quran, used to justify wars with other countries.

"He had nothing against the American people," Ammon said. "He had something against the American government."

Khozhugov said Tamerlan did not know much about Islam beyond what he found online or what he heard from Misha.

"Misha was important," he said. "Tamerlan was searching for something. He was searching for something out there."

Scientists advance understanding of human brown adipose tissue and grow new cells

Apr. 22, 2013 ? oslin scientists report significant findings about the location, genetic expression and function of human brown adipose tissue (BAT) and the generation of new BAT cells. These findings, which appear in the April 2013 issue of Nature Medicine, may contribute to further study of BAT's role in human metabolism and developing treatments that use BAT to promote weight loss.

Two types of adipose (fat) tissue -- brown and white -- are found in mammals. Unlike the more predominant white adipose tissue (WAT) which stores fat, BAT burns fat to produce heat when the body is exposed to cold and also plays a role in energy metabolism. Human studies have shown that greater quantities of BAT are associated with lower body weight. BAT has been a major focus of study among scientists and pharmaceutical companies based on its potential as a treatment to combat obesity, a major risk factor for type 2 diabetes.

Studies in mice have identified two types of BAT: constitutive or "classical" BAT which is present at birth and persists throughout life and recruitable or "beige" BAT which can be produced from within white fat in response to metabolic conditions. These two types of BAT may also be present in humans.

Previous studies have identified the human neck as a primary location for BAT deposits. To determine the precise locations of these deposits, Joslin scientists obtained fat samples from five neck regions of patients undergoing neck surgery. Analysis of the samples showed that BAT was most abundant in deep regions of the neck, near the carotid sheath and longus colli muscles. These samples expressed the BAT marker gene, uncoupling protein 1 (UCP1), which is involved in heat generation. "BAT is most abundant in the deep locations of the neck, close to the sympathetic chain and the carotid arteries, where it likely helps to warm blood and raise body temperature. Now that we know where brown fat is, we can easily collect more cells for further study," says Aaron M. Cypess, M.D., Ph.D., senior author and Assistant Investigator in the Section of Integrative Physiology and Metabolism and Assistant Professor at Harvard Medical School.

In analyzing genetic expression in superficial and deep human neck fat tissue, the fat from deep locations was found to most closely resemble cells from constitutive mouse BAT, the kind already known to consume large quantities of glucose and fat.

The Joslin scientists compared the oxygen consumption rate (OCR), which demonstrates the capacity to burn calories, of human BAT cells to mouse constitutive BAT cells and human WAT. This is the first study to directly measure brown fat cells' OCR at baseline. The OCR of the human BAT cells from the deep location next to the longus colli was nearly 50 percent of the mouse BAT cells; in contrast, the OCR of human WAT was only one-hundredth of the OCR found in the most active human BAT from the longus colli depot. "We show that at baseline, brown fat cells have a great capacity to burn fat," says Dr. Cypess.

The scientists were able to grow new functional brown fat cells (adipocytes) by differentiating precursor cells (preadipocytes) derived from both superficial and deep human neck fat tissue. When stimulated, the cells expressed the same genes as naturally occurring brown fat cells. This is the first report of the production of brown fat cells (adipogenesis) that can respond to pharmacological stimulation.

The Joslin scientists are following up on this study to learn more about the functions of BAT, including how it affects energy balance and uses glucose. Having the ability to produce brown fat cells outside the body will make it possible to develop drugs and other potential treatments that increase BAT activity to combat obesity. "Our research has significant practical applications. If we stimulate the growth of brown fat in people, it may burn their white fat and help them lose weight, which lessens insulin resistance and improves diabetes," says Dr. Cypess.

This study was funded by grants from the National Institute of Diabetes and Digestive and Kidney Diseases of the National Institutes of Health, Harvard University and its affiliated academic health care centers, the Harvard Stem Cell Institute, and Eli Lilly Foundation.

Graphic profiles eight retiring U.S. senators

(AP) ? Senate Finance Committee Chairman Max Baucus of Montana announced plans Tuesday to retire at the end of his term after a career of enormous power and notable independence, producing both collaboration and conflict with fellow Democrats on major tax and health care legislation.

"I don't want to die here with my boots on. There is life beyond Congress," the 71-year-old Baucus said in a telephone interview with The Associated Press.

He became the eighth senator to announce retirement plans for 2014, and the sixth Democrat. One public poll recently suggested he would have faced a difficult challenge if he had sought a seventh term.

Republicans must gain six seats in 2014 to win a majority, and they said the retirement enhanced their prospects.

Yet Democrats were cheered when former Democratic Gov. Brian Schweitzer, who recently stepped down after two terms, swiftly expressed interest in the race.

In a brief statement, President Barack Obama said Baucus "has been a leader on a broad range of issues that touch the lives of Americans across the country."

Sen. Chuck Grassley, an Iowa Republican and Baucus' frequent legislative partner, was complimentary, too. "We ran the Finance Committee for 10 years together, and every bill except for three or four was bipartisan," he said in a statement. "The Senate will be worse off as a deliberative body when Senator Baucus leaves."

In a written statement, Baucus sketched an ambitious agenda for the rest of his term, topped by an overhaul of the tax code.

"Our country and our state face enormous challenges - rising debt, a dysfunctional tax code, threats to our outdoor heritage and the need for more good-paying jobs," he said, adding several Montana-specific priorities as well.

Baucus, a fifth-generation Montanan, was elected to the Senate in 1978 after two terms in the House. He became the top Democrat on the Finance Committee in early 2001. He has held the position ever since on the panel ? which has jurisdiction over taxes, Medicare, Medicaid, health care and trade ? as chairman when his party held a majority and as senior member of the minority when Republicans were in power.

The panel has a long tradition of bipartisanship, but Baucus ascended to power in an era of increasing partisanship in Congress.

Many Democrats were unhappy when he worked with Republicans to enact the tax cuts that President George W. Bush won in 2001. And then again in 2004 when Congress pushed through a GOP plan to create a new prescription drug benefit under Medicare, a measure that most Democrats opposed as a giveaway to the large drug companies.

Baucus stood with fellow Democrats in 2005 when Bush proposed legislation to partially privatize Social Security, an epic battle that ended in defeat for the president's effort.

He played a central role in the enactment of Obama's watershed health care legislation in 2010, although some inside his party complained that precious momentum was lost while he spent months on bipartisan negotiations that ultimately proved fruitless.

More recently, Baucus has expressed opposition to Democratic proposals to use an overhaul of the tax code as a means of raising additional revenue. He was one of four members of his party to oppose the budget the leadership brought to the floor with a requirement to that effect.

On other issues large and small, Baucus' voting record reflected his rural state.

Most recently, he voted against legislation that Obama backed to expand background checks for gun purchasers.

During the debate on the budget, he was the only Democrat to vote for a proposal to reopen White House tours. Most members of his party viewed the GOP measure as an attempt to embarrass Obama, but it would also have meant more money for clearing snow from the entrances to Yellowstone National Park, a portion of which is in Montana.

For more than a decade, Baucus has sought federal assistance for the residents of Libby, Mont., where asbestos contamination from a vermiculite mine has been linked to deaths and illnesses.

Sen. Jon Tester, D-Mont., said he learned of the retirement plans on Monday. He said Baucus told him he wanted to return to Montana, and noted that if he waited until the end of his next term he would be nearly 80.

Baucus, in the interview with the AP, said: "Been here 40 years. No regrets. It is time to do something different."

Maneuvering began almost instantly for the 2014 race.

"The opportunity to try and get the country moving again like we did in Montana, that's appealing," said Schweitzer, who outpolled Baucus in a hypothetical matchup in the recent poll. "I'm a fixer."

Possible Republican candidates include former Gov. Marc Racicot; former Rep. Denny Rehberg, who lost to Baucus in 1996 and to Tester last fall; former Rep. Rick Hill and Rep. Steve Daines. State Sen. Champ Edmunds of Missoula and former state Sen. Corey Stapleton, had already announced they would run against Baucus.

"Montana is a state where Republicans can and will do well," said Sen. Jerry Moran of Kansas, the GOP campaign committee chairman, pledging to provide the resources needed to turn the seat Republican.

The state twice voted against Obama in presidential races. Despite the president's presence on the ticket in 2012, Tester won a second term in a hotly contested challenge, and another Democrat, Steve Bullock, was elected governor.

Sen. Michael Bennet, D-Colo., who heads the Democratic Senatorial Campaign Committee, touted last year's re-election of Tester and said, "We will continue to invest all the resources necessary to hold this seat."

Democrats will be defending 21 seats next year, compared with 14 for Republicans.

Baucus joined Jay Rockefeller of West Virginia, Frank Lautenberg of New Jersey, Tim Johnson of South Dakota, Tom Harkin of Iowa and Carl Levin of Michigan in announcing his retirement plans.

Republicans Saxby Chambliss of Georgia and Mike Johanns of Nebraska also have decided not to seek re-election next year.

Apple's Pile Of Cash Is Still Growing, Up 6% To $145 Billion

Pile of cashApple now has $145 billion in cash on hand — a 5.8 percent increase over the past three months. The company last reported that they had $137.1 billion in cash back on December 30. To put this into perspective, with $140 million, you can produce the movie Spider-Man. Apple has enough money to produce a thousand blockbusters. Apple could use its cash to acquire some companies. But with more than $145,000,000,000, you can acquire a lot of companies. For example, Facebook’s market capitalization is only $61.89 billion. If Apple would use all of its cash to acquire Facebook, it would still pay a nice premium. With $9.5 billion in profit and little operating expenses, Apple’s cash will likely grow over the next three months. Yet, Apple doesn’t seem to be ready to use its cash on hand (short-term investments). Now that Apple is handing out dividends, its cash is one of the remaining issues with investors. Shareholders wants Apple to actually use this cash for something — acquisitions, big investments dividends or other financial activities (such as a share buyback). The company likes to tap into its deep pockets to secure deals with its production line in order to make sure its supply chain is efficient. But that still leaves a lot of cash. Apple is still sitting on over $145 billion without any plan in sight.

Experimental therapy saves child born 'without bones'

Apr. 22, 2013 ? Four years ago, Janelly Martinez-Amador was confined to a bed, unable to move even an arm or lift her head. At age 3, the fragile toddler had the gross motor skills of a newborn and a ventilator kept her alive.

She was born with thin, fragile bones, and by 3, she had no visible bones on X-rays. Initially, doctors weren't sure she would survive her first birthday. In May, Janelly will turn 7, and is developing bone with the help of an experimental drug therapy and her care team at the Monroe Carell Jr. Children's Hospital at Vanderbilt.

Janelly has a rare genetic disorder called hypophosphatasia (HPP), a metabolic disease that affects the development of bone and teeth. An enzyme deficiency causes the bones to become soft because they can't absorb important minerals such as calcium and phosphorus, increasing the risks for pain, broken bones and bone deterioration.

"Imagine your child laying all the time in bed, not being able to lift herself, not being able to move herself, making sure she is not falling or tripping on things," her father, Salvadore Martinez, said through a Spanish interpreter.

"The treatment has worked very well but it has been a compilation of doctors, nurses, assistants ? everyone that has been a part of her care that has helped her make a meaningful recovery."

HPP affects about one in 100,000 babies born in the United States. While there are varying degrees of severity, the most severe forms of HPP occur before birth and early infancy. More than half of babies born with the disease don't survive beyond their first birthday. Janelly has the more severe form of the disease, which was diagnosed when she was 3 months old after failing to grow and gain weight. Doctors initially thought she might have cancer. With a thorough blood analysis at Children's Hospital, they diagnosed her with HPP.

"If you saw her in 2009 and see her now, it's not the same Janelly," said her mother, Janet Amador. "She used a ventilator, an oxygen mask -- many machines to help her breathe."

Janelly is one of 11 children, age 3 years and younger, to participate in a clinical trial to receive an enzyme-replacement drug therapy, asfotase alfa, for the life-threatening form of HPP. She had the worst case of the group.

Michael Whyte, M.D., the lead investigator of the study, which published results in March, 2012, in the New England Journal of Medicine, visited Janelly and her family at Children's Hospital last week. It was the first time he had met the family and her physician, Jill Simmons, M.D., a pediatric endocrinologist at Vanderbilt.

"It's wonderful that you had the faith that a treatment might come along. For many years, it seemed there was nothing that was very helpful for this disorder," said Whyte, medical-science director of the Center for Metabolic Bone Disease and Molecular Research at Shriner Hospitals for Children in St. Louis.

"We were fearful that her bone disease was so terribly severe that it might not work. But by looking at the X-rays and hearing about her visits, we were thrilled to hear about her progress."

About eight months into the treatment, Janelly's parents felt her fingers -- which had been completely soft and boneless -- and they could feel traces of developing bone. Her head also began to develop bone. At 18 months into therapy, X-rays showed, for the first time, the visible development of her rib cage.

Janelly now sits in a wheelchair. Recently, dressed in her Easter best and bright pink bows, she was able to turn her head to gaze at a room of onlookers.

She smiled and waved her hand excitedly, a feat she never would have accomplished before the drug therapy. She is also able to attend school at Harris-Hillman Special Education School, not far from Children's Hospital.

This spring, doctors hope to be able to remove her tracheostomy tube, which has prevented her from speaking. Her developmental and cognitive abilities will be tested in July. Improvement continues each day, each week for Janelly.

"This is why we get into medicine in the first place: to truly make a difference in the life of a child," said Simmons, her physician. "My goodness, to go from no bones to bones. That's the most impressive thing I have seen as a physician. It's incredible."

Pentax WG-3


The Pentax WG-3 ($299.95 direct)?is the latest in the company's line of go-anywhere point-and-shoot?cameras. The 16-megapixel shooter offers numerous upgrades compared with last year's WG-2 GPS?including a faster, sharper lens, sensor shift image stabilization, and overall improved image quality. Its photos are a bit noisy, and they don't look quite as good as images captured by our current Editors' Choice rugged camera, the Olympus Tough TG-1 iHS. That model has been replaced by the Olympus TG-2, which we haven't tested? yet?the TG-2 features the same lens, image sensor, and imaging engine as the TG-1, so we expect it to perform similarly.

Editors' Note: This review is based on tests performed on the Pentax WG-3 GPS, a camera that adds a GPS radio, inductive charging, and a front information LCD, but is otherwise identical. While we didn't perform lab tests on this specific model, we expect similar performance.

Design and Features
The WG-3 is one of two version of this camera that are marketed by Pentax. The other, the WG-3 GPS for $50 more; it adds a GPS, support for Qi wireless charging, and a monochrome front information display. The WG-3 GPS is available in green or purple, while the WG-3 can be had in orange or black. Otherwise, the cameras are identical.

The WG-3 features a bold design that combines bright, metallic colors with a body style that's a bit wider than most compact cameras. It measures 2.5 by 4.9 by 1.3 inches and weighs 8.1 ounces. Compare this with the funky, rugged Canon PowerShot D20, despite having some curvy lines as part of its design, the D20 is more traditionally proportioned?it measures 2.8 by 4.4 by 1.1 inches and weighs 8 ounces. In addition to a standard flash, there are six LEDs that surround the lens to provide even illumination when shooting in macro mode. They can be activated via the menu, and automatically turn on when you set the shooting mode to Digital Microscope?a special setting that lets you focus on objects as close as 1 centimeter from the lens.

The lens is a 4x zoom design that is fairly wide when zoomed out. The 25-100mm f/2-4.9 (35mm equivalent) zoom is also quite bright at the wide end, which is helpful for underwater shooting. As a general rule of thumb, you'll want to get as close as possible to what you're photographing under the sea, as even the cleanest water will cloud your field of view when you're further away from the fish or coral reef that you're trying to capture. The lens doesn't capture as much light when zoomed in, but that shouldn't be an issue when using the camera outdoors in the daylight.

The shutter release and power button are located on the top of the WG-3, with other controls on the back to the right of the LCD. There's a zoom control button, a dedicated movie button, as well as controls to activate the self-timer, enable macro shooting, change the shooting mode, and control the flash. It's a Pentax camera, so you also have the company's trademark Green button, which brings up a software menu that has four customizable functions, each mapped to a different direction on the standard four-way control pad. By default these adjust ISO, EV Compensation, the focusing area, and enable automatic macro shooting, but you can customize them to best suit your shooting style.

The 3-inch 460k-dot LCD is wider than what you'll usually see on a point-and-shoot camera. It has a 16:9 aspect ratio, the same as HD video. The image sensor is actually a 4:3 design, but there's a crop mode that records 12-megapixel 16:9 images if you prefer to shoot wider. It's not as crisp as the 610k-dot OLED found on the Olympus TG-1 and TG-2, but it's much crisper than the 230k-dot display found on the budget-minded Panasonic Lumix DMC-TS20.

The camera is rated for use in water as deep as 45 feet, which is five feet deeper than the previous model. It's strong enough to withstand pressure of up to 220 foot-pounds and to survive drops from heights of 6.6 feet. And it can shoot in temperatures as low as 14?F, good news for those who live in or enjoy spending time in frigid environments. It can go a bit deeper than the Olympus TG-1, that's limited to 40 feet, but the newer TG-2 hits 50 feet.

Performance and ConclusionsPentax WG-3 : Benchmark Tests
The WG-3 starts and captures an in-focus shot in about 2.5 seconds, can fire off shots continuously with 0.7 second between each photo, and records a 0.2-second shutter lag. The Canon D20 is faster to operate?it starts and shoots in 1.4 seconds, fires off a photo every 0.5 second, and records a 0.2-second shutter lag.

The WG-3's startup speed is hindered by a bit of human reaction time that normally isn't a factor in our testing. Holding down the shutter release all the way after hitting the power button is our usual methodology, but doing so with the WG-3 activates a pan focus function that focuses on distant objects and doesn't engage the autofocus system. The camera is able to start up and grab a shot in this mode in about 1.8 seconds, which is still not the speediest result. If you don't take care when shooting a photo while you're out and about you can fall into the trap of accidentally triggering pan focus when you'd rather focus on something closer. You can disable it by engaging the macro shooting function?it will always confirm focus when capturing a photo if that is on. Unfortunately, the camera does not remember to leave macro on after powering down.

I used?Imatest?to check the sharpness of photos captured by the WG-3's lens. At its widest angle and aperture it scored 1,948 lines per picture height. This is better than the 1,800 lines we require for a photo to be sharp, and it's an exceptional score for a rugged camera with such a fast lens.? This is one area in which the Olympus TG-1 struggles; it only scored 1,656 lines, mainly due to softness at the edges and corners of photos.

As you increase a camera's ISO it becomes more sensitive to light, but with that extra sensitivity comes noise in the form of graininess and loss of detail. The WG-3 doesn't do a great job in this regard; it can only keep noise below 1.5 percent through ISO 200. Detail is pretty decent at ISO 400, even with 1.7 percent noise, but once you've set the camera to ISO 800 or above, image quality deteriorates quickly. Images are a huge step up from the WG-2, but can't keep up with competitors in this class at higher ISO settings. The Canon D20 controls noise through ISO 800 and its images at ISO 1600 and ISO 3200 are much better than those from the WG-3.

Video quality is a mixed bag. The WG-3 does capture footage at 1080p30, 720p60, or 720p30 in QuickTime format. Footage is sharp and colors are accurate, but the sound of the lens refocusing is audible on the soundtrack. In fact, if you zoom in or out, the sound of the lens moving is overwhelming.

There's a micro HDMI port, housed in the battery compartment, as well as a proprietary USB port. The latter doubles as the connector for in-camera charging. There's no dedicated battery charger included. Standard SD, SDHC, and SDXC memory cards are supported.

The WG-3 is one of the more interestingly designed tough cameras on the market. Its lens is fast and sharp, it can go deep underwater, and the LED lights around the lens are a great tool for macro photography. Its image quality is noticeably better than the WG-2, but it still lags behind the Olympus TG-1 at medium to high ISO settings. It lacks the inductive charging and GPS that are available on the WG-3 GPS, but is priced at $50 less. If you generally shoot in brighter light, you'll be quite happy with the images you'll get from the WG-3, but if you find yourself in situations where you need to shoot at a higher ISO the Canon PowerShot D20 is a better choice, but it is a little bit more expensive.

Facebook building $1.5 billion data center in Altoona, Iowa

DNP  Facebook building $15 billion data center in Altoona, Iowa

Facebook has already set up shop in North Carolina and Oregon, but it's heading to Iowa for its next -- and biggest -- data center. According to the Des Moines Register, the town of Altoona will be home to a 1.4-million-square-foot facility (code-named Catapult), and it will reportedly be the "most technologically advanced center in the world." Why Altoona, you ask? The city is already home to several data hubs, as its fiber-optic cable system, access to power and water utilities and affordable land are big draws for companies. Facebook will complete project Catapult in two $500 million phases, though the entire cost will reportedly ring in at $1.5 billion. The social network is also seeking wind energy production tax credits, which is no doubt connected to its Open Compute Project for promoting energy efficiency. That's all we know so far; suffice to say a center this big won't be built overnight.
