Owner arrested as Bangladesh building toll reaches 372

By Serajul Quadir and Ruma Paul

DHAKA (Reuters) - Hope for survivors under the rubble of a building that collapsed outside the capital of Bangladesh faded on Sunday, and with more than 900 people still counted as missing fears grew that the death toll could rise far beyond the latest figure of 363.

Four people were pulled alive from the wreckage of the Rana Plaza, which housed several factories making low-cost garments for Western retailers, four days after the country's worst-ever industrial accident.

Rescuers worked frantically through the morning to release several others who fire service Deputy Director Mizanur Rahman said were trapped under the mound of broken concrete and metal.

"The chances of finding people alive are dimming, so we have to step up our rescue operation to save any valuable life we can," said Major General Chowdhury Hassan Sohrawardi, coordinator of the operation at the site.

About 2,500 people have been rescued from the remains of the building in the commercial suburb of Savar, about 30 km (20 miles) from the capital, Dhaka.

Officials said the eight-storey tower had been built on spongy ground without the correct permits, and more than 3,000 workers - mainly young women - had been sent in on Wednesday morning despite warnings that it was structurally unsafe.

Police said one factory owner gave himself up following the detention of two plant bosses and two engineers the day before.

The owner of the building, identified by police as Mohammed Sohel Rana, a leader of the ruling Awami League's youth front, was still on the run. Airport and border authorities have been alerted to prevent Rana from fleeing the country.

Police have also detained several of his relatives to compel him to surrender and to find out where he might be. Local news reports said his mother, who was not being held, died of a heart attack on Saturday evening.

Anger at the negligence sparked days of protests and clashes, with police using tear gas, water cannons and rubber bullets to quell demonstrators who set cars ablaze. On Sunday, however, the roads were quiet.

The main opposition, joining forces with an alliance of leftist parties which is part of the ruling coalition, called for a national strike on May 2 in protest over the incident.

BUILT ON A FILLED-IN POND

Wednesday's collapse was the third major industrial incident in five months in Bangladesh, the second-largest exporter of garments in the world behind China. In November, a fire at the Tazreen Fashion factory in a suburb of Dhaka killed 112 people.

Such incidents have raised serious questions about worker safety and low wages, and could taint the reputation of the poor South Asian country, which relies on garments for 80 percent of its exports. The industry employs about 3.6 million people, most of them women, some of whom earn as little as $38 a month.

Emdadul Islam, chief engineer of the state-run Capital Development Authority (CDA), said on Saturday that the owner of the building had not received the proper construction consent, obtaining a permit for a five-storey building from the local municipality, which did not have the authority to grant it.

"Only CDA can give such approval," he said. "We are trying to get the original design from the municipality, but since the concerned official is in hiding we cannot get it readily."

Furthermore, another three storeys had been added illegally, he said. "Savar is not an industrial zone, and for that reason no factory can be housed in Rana Plaza," Islam told Reuters.

Islam said the building had been erected on the site of a pond filled in with sand and earth, weakening the foundations.

Since the disaster, the Bangladesh Garment Manufacturers and Exporters Association (BGMEA) has asked factory owners to produce building designs by July in a bid to improve safety.

Success in observation of swelling of single-particle of silicon electrode for lithium ion batteries during charging reaction

Apr. 26, 2013 ? The NIMS Global Research Center for Environment and Energy based on Nanomaterials Science (GREEN) and Tokyo Metropolitan University have measured the volumetric expansion of single particles of silicon accompanying the charging reaction. This finding demonstrated the importance of electrode design from the viewpoint of volumetric energy density.

The NIMS Global Research Center for Environment and Energy based on Nanomaterials Science (GREEN) and a research group at Tokyo Metropolitan University succeeded in measuring the volumetric expansion of single particles of silicon, which is a negative electrode material for lithium ion batteries, accompanying the charging reaction, and demonstrated the importance of electrode design from the viewpoint of volumetric energy density based on this finding.

A research group headed by Dr. Kiyoshi Kanamura (NIMS Special Researcher) and Dr. Kei Nishikawa (Postdoctoral Researcher) at the Global Research Center for Environment and Energy based on Nanomaterials Science (GREEN) of the National Institute for Materials Science (President: Sukekatsu Ushioda), in joint research with Tokyo Metropolitan University (President: Fumio Harashima), succeeded in measuring the volumetric expansion of single particles of silicon, which is a negative electrode material for lithium (Li) ion batteries, accompanying the charging reaction, and demonstrated the importance of electrode design from the viewpoint of volumetric energy density.

Li-ion batteries are a type of secondary cell in which a Li-containing transition metal oxide is used as the positive electrode and graphite is used as the negative electrode. Because Li-ion batteries have high energy density in comparison with other secondary cells, such as nickel-metal hydride (NIMH) batteries, etc., they are widely used as a power source for mobile electronics, and are also considered promising for electric vehicle (EV) and stationary power storage applications. At present, graphite is used as the negative electrode material, but in order to achieve higher energy density, materials which utilize the alloying reaction with lithium, represented by silicon, have attracted attention as next-generation negative electrode materials. The most important issues for practical application are elucidation of the mechanism of the large volume change which occur in the charging and discharging reactions, and control of those changes.

Researchers at Tokyo Metropolitan University established the technology of a single-particle measurement system to investigate the intrinsic electrochemical properties of single particles of electrode materials for Li-ion batteries. In the present research, this system was introduced in the ultra-dry room at the NIMS Global Research Center for Environment and Energy based on Nanomaterials Science (GREEN), and was used to perform electrochemical measurements of single particles (10-20?m) of silicon, which is seen as a next-generation negative electrode material. To date, the expansion ratio, etc. of single particles of silicon had been estimated from the theoretical crystal size, and volumetric changes accompanying the charging and discharging reactions had not been evaluated quantitatively. This research result was the world's first example of successful measurement of volumetric expansion of a single particle of silicon accompanying the charging reaction.

The results of this experiment clarified the fact that the volumetric expansion of silicon in the charging reaction is larger than the value estimated theoretically. Although this is thought to be due to the formation of an amorphous phase, etc. as the alloying reaction between the lithium and silicon proceeds, further study will be necessary in order to elucidate the detailed mechanism. Standards have now been established for Li-ion batteries for electric vehicle (EV) and cellphone applications. Conventionally, evaluations of material performance had centered on energy density per unit of mass. However, volumetric energy density is increasingly considered more important than mass energy density. As the present research showed, silicon displays larger volumetric expansion than the predicted value, which results in a decrease in real energy density. Thus, this research demonstrated the importance of actual measurement of volumetric expansion in the search for candidates for next-generation battery materials.

As described above, this research showed the importance of measuring the actual volumetric energy density when adopting a material that displays volumetric changes during charging/discharging in the electrodes of Li-ion batteries. Based on this result, electrode design guidelines which also consider volumetric changes are necessary in research and development in the search for next-generation materials for Li-ion batteries.

These research results was presented at the 80th Spring Meeting of the Electrochemical Society of Japan, which was held at Tohoku University on March 29.

The iTunes Store Is A Decade Old Today

For better or worse, Apple has been peddling digital wares for ten years through its iTunes store. What started as a 99 cent, iPod-centric music seller has evolved into the billion dollar behemoth we know today.

iTunes sells 35 million songs in 119 countries, movies in 109 countries and 850,000 iOS apps in 155 countries. After launching iTunes in 2003, Apple added podcasts in 2005, movies in 2006, and the App Store in 2008, along with iTunes U. It's not the most navigable or inexpensive place to shop for media, but the iTunes store is deeply embedded in the Apple ecosystem.

Tomorrow will be just another day of downloads and syncing, but today you can reminisce about the top albums and songs from every year that iTunes has been around, and continue to be nonplussed by the fact that the iTunes store eventually got to sell Beatles music. [MacRumors, AppAdvice]

Obama pokes fun at critics, media at annual press dinner

By Jeff Mason

WASHINGTON (Reuters) - President Barack Obama poked fun at the media, his critics and himself on Saturday at the annual White House Correspondents' Association dinner, a star-filled event where journalists and celebrities mixed with the Washington elite.

Joined at the dinner by his wife, first lady Michelle Obama, the president gently knocked Republicans for not working with him on policy priorities and made a rare reference to his race when urging the opposition party to be cooperative.

"I know Republicans are still sorting out what happened in 2012, but one thing they all agree on is they need to do a better job reaching out to minorities," Obama said.

"And look, call me self-centered, but I can think of one minority they could start with. Hello? Think of me as a trial run, you know?" he said.

Obama, a Democrat and the first black U.S. president, won re-election in November with overwhelming support from minority voters including blacks and Hispanics.

He took a swipe at people who have doubted his religion and accused him of being a radical leftist, while he made light of his graying hair.

"These days, I look in the mirror and I have to admit, I'm not the strapping young Muslim socialist that I used to be," Obama said. "Time passes. You get a little gray."

The president is a Christian who was born in Hawaii, but he included some material for so-called "birthers" who falsely assert he was born abroad.

"I'm also hard at work on plans for the Obama Library, and some have suggested that we put it in my birthplace, but I'd rather keep it in the United States," he said.

Obama made light of his own rapid rise to power by comparing himself to Republican Senator Marco Rubio, a Hispanic from Florida who is touted as a potential presidential candidate in 2016.

"One senator who has reached across the aisle recently is Marco Rubio, but I don't know about 2016. I mean, the guy has not even finished a single term in the Senate and he thinks he's ready to be president," Obama joked. "Kids these days."

Obama began running for president during his first term as a U.S. senator from Illinois.

In a room filled with journalists, the president saved some of his most biting jokes for the press.

"I know CNN has taken some knocks lately, but the fact is I admire their commitment to cover all sides of a story, just in case one of them happens to be accurate," he said, drawing applause.

"Some of my former advisors have switched over to the dark side. For example, David Axelrod now works for MSNBC, which is a nice change of pace since MSNBC used to work for David Axelrod."

Axelrod was the chief strategist for Obama's re-election campaign and a former White House adviser. MSNBC is considered to be a liberal-leaning television network.

Obama also made light of his wife's new bangs, drawing laughter from her when he showed mock pictures of himself with the same hairdo.

NATO crash kills 4; Taliban begin spring offensive

KABUL, Afghanistan (AP) ? A NATO plane crash in southern Afghanistan killed four international troops on Saturday, the same day the Taliban announced its spring offensive and said it will target military and diplomatic sites with suicide bombers and infiltrate enemy forces to conduct deadly insider attacks.

April already has been the deadliest month so far this year across the country where Afghan security forces are increasingly taking the lead on the battlefield of the more than 11-year-old war.

The Afghan Defense Ministry said its security forces were prepared for the Taliban's new campaign, which was to start on Sunday. "The Afghan National Army is ready to neutralize the offensive," the ministry said.

Insurgents have escalated attacks to gain power and influence ahead of next year's presidential election and the planned withdrawal of most U.S. and other foreign combat troops by the end of 2014. And U.S.-backed efforts to try to reconcile the Islamic militant movement with the Afghan government are gaining little traction.

The Taliban did not immediately claim responsibility for the plane crash. NATO said initial reports indicated no enemy activity in the area where the plane went down. Coalition personnel secured the site and were investigating the cause of the crash.

The brief NATO statement did not identify the victims, or say exactly where the crash occurred in Afghanistan. However, Mohammad Jan Rasoulyar, deputy governor of the southern province of Zabul, said an aircraft belonging to foreign forces crashed Saturday afternoon in Shah Joy district.

In their announcement on Saturday, the Taliban vowed to step up violent attacks now that winter was over and warmer weather has made travel and fighting easier. The militant group said it would use every possible tactic to "detain or inflict heavy casualties on the foreign transgressors."

Taliban fighters, who seek to replace the elected Afghan government with one promoting a stricter interpretation of Islamic law, named their offensive after a legendary Muslim military commander, Khalid ibn al-Walid. Also known as the "Drawn Sword of God," he was a companion of Islam's Prophet Muhammad.

The Taliban threatened to infiltrate the Afghan security forces and conduct more attacks on Afghan policemen and soldiers as well as foreign troops.

Such attacks threaten the strength of the Afghan forces as they work to take over responsibility from coalition forces. The latest one occurred in March, when a member of a government-backed village defense unit shot and killed five of his colleagues in Badghis province in northwest Afghanistan.

April has already been the worst month for combat deaths so far this year. According to an Associated Press tally, 261 people ? including civilians, Afghan security forces and foreign troops ? have been killed in violence around the nation. During that time 217 insurgents have died.

Last year during the month of April, 179 civilians, foreign troops and Afghan security forces were killed and 268 insurgents.

Still, U.S. Marine Gen. Joseph Dunford, the top commander of U.S. and NATO forces in Afghanistan, said Wednesday that the security situation had improved across the country, with Afghan forces now leading 80 percent of all conventional operations.

As the traditional fighting season begins, the insurgents will face a combined Afghan force of 350,000 soldiers and police, he said.

"The insurgency can no longer use the justification that it is fighting foreign occupiers ? that message rings hollow," Dunford said in a statement.

Taliban spokesman Zabiullah Mujahid disagreed with that assessment.

"The foreign forces will be our primary targets. The second target will be the government of Kabul. The third one will be the other foreign countries who are acting against our mujahedeen," or holy warriors, he said in an interview with AP Television News.

Conversion from 'bad' fat to good fat

Apr. 28, 2013 ? Scientists from ETH Zurich have shown for the first time that brown and white fat cells in a living organism can be converted from one cell type to the other. Their work, using mice as a model organism, provides important new insights into the origin of brown fat cells, which is a prerequisite for the development of successful anti-obesity therapies.

Two types of fat cells can be found in mammals and hence in humans: White fat cells function mainly as highly flexible energy stores which are filled in times of calorie abundance. The fat is stored in the form of lipid droplets, which are mobilized when energy is needed. Diametrically opposed in function are the so-called brown adipocytes: These cells specialize in burning energy in the form of fat and sugar to produce heat. New-born babies possess substantial amounts of brown fat and utilize it to maintain body temperature. Since it was recently shown that brown adipocytes also exist in adult humans, research has focused on understanding how brown adipocytes are formed. The ultimate goal of these efforts is to increase brown adipocyte number and activity in obese humans, allowing them to burn excess calories and thus reduce weight.

Against the current belief

It is known that both humans and mice can adapt to cold temperatures by forming brown fat cells within their white fat depots. These cells are called "brite" fat cells (brown-in-white) and are less common at warmer versus colder temperatures. However, the origin of these special brown adipocytes has remained a matter of debate. The prevalent hypothesis was that brite cells are formed from special precursor cells and are removed when no longer needed. The alternate idea of a direct interconversion between white and brown fat cells gained less attention. By demonstrating that this interconversion does occur and is one of the main contributors to brite fat cell formation, the current belief has been challenged.

Genetically labelled fat cells

To demonstrate how brite fat cells are formed the researchers in the laboratory of Christian Wolfrum, a professor at the Institute of Food, Nutrition and Health, generated mice that allowed them to genetically label specific fat cells. These animals were kept in a changing environment: starting at 8?C for a week and for several weeks afterwards at normal room temperature. During the cold exposure, the mice formed brown adipocytes in their white fat depots -- a process called "britening." After warm adaptation the fat tissue turned white again. Using the genetic markers the scientists concluded from these experiments that white fat cells can convert into brown fat cells and vice versa. As humans have the same type of cells as mice it is likely that the same process occurs in humans upon cold stimulation.

Treatments against obesity

"To develop new treatment strategies we need to find ways to convert white into brown adipocytes," says Wolfrum. Most of the research has focused on identifying the precursor cells for brown fat cells, an approach that may be insufficient. Future work will address the question of how to manipulate this interconversion process either by pharmacological or by nutritional means.

This approach would represent a novel strategy. "Current anti-obesity therapies target the energy intake side of the equation by controlling appetite and the uptake of nutrients," says Wolfrum. The pharmacological treatments that are available are not very efficient and usually are associated with side effects. In contrast, this novel approach to treat obesity would target the energy expenditure side of the equation by promoting brown fat formation.

Insurance Cards Could Go Digital Under Missouri Bill ? CBS St. Louis

JEFFERSON CITY, Mo. (AP) ? The smartphone era could spare Missouri motorists from digging through their glove boxes for their insurance cards when they?re stopped by law enforcement.

State senators passed legislation (SB317) Thursday that would authorize drivers to show digital images of their proof-of-insurance cards to law enforcement officers or state licensing clerks instead of having to present a piece of paper. The bill now goes to the House.

The legislation is sponsored by Republican Sen. Gary Romine, of Farmington. He says paper insurance cards easily get lost in vehicle glove boxes. But he says many people now have a smartphone readily available at their side.

The bill says police and licensing clerks cannot be held liable if they accidentally drop a person?s smartphone while verifying vehicle insurance.

'One Life to Live' divas will duke it out

By Michael Maloney, TODAY contributor

Just like a phoenix -- and Victor Lord, more than once -- "One Life to Live" is rising from the ashes. The axed ABC serial returns Monday, April 29 as a Web soap on The Online Network -- and on Hulu and iTunes, too. The show's revival came as a pleasant surprise not only to fans but also the actors on the show.

David M. Russell

Erica Slezak and Corbin Bleu on "One Life to Life."

Fan favorite Erika Slezak, who's re-creating her role as Victoria Lord Buchanan on the Internet venture, told TODAY.com, "I always kind of hoped we'd be back, but we had our doubts."

It took Prospect Park, the company that's relaunching both "OLTL" and "All My Children," a while to iron out deals with the unions and get the shows up and running, but their efforts are now paying off. "When they called again last November, I said yes without any hesitation," Slezak said.

While fans will meet new characters and see teens Matthew and Destiny grow up, "OLTL" devotees are most looking forward to their daily dose of core characters like Viki, Clint, Bo, Nora and Dorian.

"I've always said that the dynamic between Viki and (her former stepmother) Dorian is the strongest relationship on the show," Slezak affirmed.

The show's new creative team concurs, which is why the two divas will be squaring off in the premiere episode.

"Dorian's gotten herself into a whole heap of trouble in Washington, D.C.," Slezak said. "Being Dorian, she thought she could just take care of it. Unfortunately, she can't. It comes to Viki's attention at [Llanview's newspaper] The Banner. We have to take care of it and, boy is Dorian unhappy! Day one starts with Dorian yelling at Viki."

The Viki-Dorian feud is an "OLTL" staple -- as is Viki's formal diction.

"That started when I played Miss Ginny in the Old West (storyline)," Slezak explained about Viki's refusal to use contractions. "People didn't say 'can't,' 'won't,' and 'didn't' back then. They'd say 'cannot,' would not,' and 'did not.' Somehow that carried over to Viki."

Viewers will have to tune in to see whether Slezak will also revive any of Viki's alters, including trashy Nikki Smith and calculating Jean Randolph.

"Nobody ever leaves Llanview permanently," Slezak said with a laugh. "If Victor Lord can keep coming back, you learn never to say never!"

See Saturn at Its Best In the Weekend Night Sky

In the early hours of Sunday morning (April 28), the planet Saturn reaches opposition. This places it exactly opposite the sun in our sky.

Opposition has several effects on Saturn. Most important, it marks its arrival in the evening sky. It is now visible all night long, a treat for the many people who consider this the most beautiful object in the sky. On Saturday and Sunday night, Saturn can be found in the southeastern sky, weather permitting.

Saturn's opposition also marks the planet's maximum brightness for the year, and the brightest it has been for a number of years. At magnitude 0.2, the ringed planet now outshines the first magnitude star Spica in the constellation Virgo. Astronomers measure the brightness of night sky in terms of magnitude, with lower numbers denoting exceptional brightness. [Photos of Saturn's Dazzling Rings]

You can easily spot Saturn and Spica by following the old rule: "Arc to Arcturus, then speed on to Spica." Start by following the arc formed by the handle of the Big Dipper away from the Dipper's bowl in a broad arc across the sky, first reaching Arcturus in kite-shaped Bo?tes, and then on to Spica and Saturn in Virgo. Sparkling Spica is on the right, steady Saturn on the left. Starlight, coming from a distant point, is deflected by the Earth's atmosphere and twinkles. A planet like Saturn is larger than a star in apparent size, and so is less affected by atmospheric turbulence, so shines with a steady light.

Saturn is most famous for its magnificent set of rings. All the outer planets have rings, but Saturn's are the brightest and most easily seen. Composed of small pieces of rock and ice, these rings are thin and transparent. When the rings pass in front of a star, the star's light shines through undiminished.

How much magnification do you need to see Saturn's rings? Although some people claim to have seen them with their unaided eyes, most people need a magnification of about 25 power to see that Saturn is an oval rather than a disk. For a really good view, 100 power is much better. Even so, Saturn appears much smaller in a telescope than most people expect. Although tiny, Saturn's perfection astounds all first-time viewers.

Besides its rings, Saturn has an amazing collection of moons, 62 in all. Its brightest moons are mostly in orbits in the same plane as the rings, as you can see in the chart. Its largest moon, Titan, is one of the two largest moons in the solar system; Jupiter's Ganymede is the other. These are the only two moons large enough to have extensive atmospheres. Titan is also the farthest object from Earth on which a spacecraft has landed, the unmanned Huygens probe in 2005.

Titan can be seen easily in almost any telescope. Rhea, Tethys, and Dione can be seen with a 90mm telescope. The innermost moons, Mimas and Enceladus, are more challenging because the lie so close to the bright rings.

Iapetus is Saturn's most interesting moon. Its orbit is not in the plane of the rings, but is tilted at a steep angle. Like all large moons in the solar system, it always keeps one face turned towards its planet, but one side of Iapetus is coated with a dark sooty material. This results in Iapetus being much brighter when west of the planet that when it is to the east.

Because Saturn's moons can appear at any angle from the planet, you will need to use a planetarium software program to identify the individual moons and to distinguish them from background stars. Watching them change positions from night to night is fascinating.

Saturn holds something for every skywatcher. Everyone can enjoy spotting it in the sky, and those with telescopes can admire its rings and track the dance of its many moons.

Forced exercise may still protect against anxiety and stress

Apr. 25, 2013 ? Being forced to exercise may still help reduce anxiety and depression just as exercising voluntarily does, according to a new study by researchers at the University of Colorado Boulder.

Past studies have shown that people who exercise are more protected against stress-related disorders. And scientists know that the perception of control can benefit a person's mental health. But it has been an open question whether a person who feels forced to exercise, eliminating the perception of control, would still reap the anxiety-fighting benefits of the exercise.

People who may feel forced to exercise could include high school, college and professional athletes, members of the military or those who have been prescribed an exercise regimen by their doctors, said Benjamin Greenwood, an assistant research professor in CU-Boulder's Department of Integrative Physiology.

"If exercise is forced, will it still produce mental health benefits?" Greenwood asked. "It's obvious that forced exercise will still produce peripheral physiological benefits. But will it produce benefits to anxiety and depression?"

To seek an answer to the question Greenwood and his colleagues, including Monika Fleshner, a professor in the same department, designed a lab experiment using rats. During a six-week period, some rats remained sedentary, while others exercised by running on a wheel.

The rats that exercised were divided into two groups that ran a roughly equal amount of time. One group ran whenever it chose to, while the other group ran on mechanized wheels that rotated according to a predetermined schedule. For the study, the motorized wheels turned on at speeds and for periods of time that mimicked the average pattern of exercise chosen by the rats that voluntarily exercised.

After six weeks, the rats were exposed to a laboratory stressor before testing their anxiety levels the following day. The anxiety was quantified by measuring how long the rats froze, a phenomenon similar to a deer in the headlights, when they were put in an environment they had been conditioned to fear. The longer the freezing time, the greater the residual anxiety from being stressed the previous day. For comparison, some rats were also tested for anxiety without being stressed the day before.

"Regardless of whether the rats chose to run or were forced to run they were protected against stress and anxiety," said Greenwood, lead author of the study appearing in the European Journal of Neuroscience in February. The sedentary rats froze for longer periods of time than any of the active rats.

"The implications are that humans who perceive exercise as being forced -- perhaps including those who feel like they have to exercise for health reasons -- are maybe still going to get the benefits in terms of reducing anxiety and depression," he said.

Other CU-Boulder authors include Katie Spence, Danielle Crevling, Peter Clark and Wendy Craig. All the authors are members of Monika Fleshner's Stress Physiology Laboratory in the Department of Integrative Physiology.

The research was funded by the National Institutes of Mental Health and the Defense Advanced Research Projects Agency.

First Blackmagic Pocket Cinema Camera footage flaunted (video)

Noted Blackmagic Design shooter John Brawley has released the first footage from the company's upcoming $995 Pocket Cinema Camera that might leave your DSLR green with envy. Though it's always tough to judge compressed web footage, to our eyes it looks completely untouched by the moire, aliasing and compression artifacts that tends to plague other digital cameras. While not specifying whether he used the compressed RAW setting or not, Brawley said he shot it using a Panasonic 12-35mm f/2.8 Micro Four Thirds lens with image stabilization turned on, meaning that feature's likely to be enabled on the camera when it arrives in late July. He also said he was "literally grabbing shots whilst I was shopping," which bodes well for serious filmmakers with a bit more time to spare. Head past the break to admire the video.
