98% Blackfish
All Critics (82) | Top Critics (26) | Fresh (80) | Rotten (2)
"Blackfish" is a disturbing movie, one that will make you rethink parks like SeaWorld and their value.
Blackfish is intended to rattle and provoke in the hopes of bringing about change.
"Blackfish" is grim. But then again, so is the plight of these magnificent, intelligent whales.
Informative, earnest, but less than briskly paced.
"Blackfish" makes a compelling case that the cruelty of life in captivity is the cause for a rash of fatal attacks by orcas on their trainers, aggressive behavior that no so-called killer whale ever has exhibited in the wild.
Its ultimate message is clear: Killer whales belong with their families in their natural habitat, not performing for audiences. After listening to this film's many impassioned voices, it's hard to argue.
You don't have to be anything close to a PETA loyalist or an anthropomorphist to appreciate the genuine sorrow and eventual psychosis on display in footage of these whales.
Whatever its flaws, 'Blackfish' seems likely to be the rare film that inspires real reform and that helps awaken viewers to their kinship and responsibility to the animal kingdom.
The question that "Blackfish" provokes, viscerally, is whether the education and entertainment for visitors, and profits for the company, are worth it if the animals are mistreated and unhappy. After watching "Blackfish," the answer is crystal clear.
Depressingly unsurprising.
While Blackfish isn't exactly riveting, it is thought-provoking and leaves you with the urge to admire nature in its natural habitat rather than in a contained environment.
A repetitive but still compelling piece of activist filmmaking.
An engrossing look at animal behavior.
It is gripping and thought-provoking.
As enlightening and passionate as the picture is, Cowperthwaite fails to summon the type of comprehensive journalism this type of story deserves.
The one save-the-whales movie to see when you only have time for one.
There aren't too many animal-rights documentaries that could be described as "metal," but Blackfish, one part horror movie and one part nature film, fits the bill and then some.
Cowperthwaite juxtaposes to devastating effect official PR spin with news reports and eye-witness accounts of marine park tragedies.
[An] impressive, often gripping documentary ...
Engrossing when offers alarming CSI-type forensic analysis into the death of a whale trainer [but] the narrow focus on SeaWorld raises more questions that aren't considered.

Apple iPhone 5S launch event expected to be scheduled on September 10
The iPhone 5S is said to have an improved camera and processor as usual while rumors also point towards a fingerprint scanner embedded in the home button. The iPhone 5C, in the meanwhile, is expected to come in a variety of colors with a plastic casing. Typically Apple has lowered the prices of its older iPhones rather than launching a low-cost variant, which could change this year. The iPhone 5C is speculated to be priced around $300 unsubsidized and would target non-carrier subsidy markets like India.
As is tradition, Apple will also unveil the final version of iOS 7, which it had first showcased at its annual WWDC event for developers in June that sports completely refreshed icons and numerous UI tweaks. Apple also unveiled a new version of OS X caller Mavericks but it would host another event aimed at Macs as typically this event is exclusively dedicated for the iPhone.
This will be the first major launch event for Apple this year as it has not hosted any iPad event in March-April timeframe as it has done since the first iPad was launched in 2010. Apple is also said to be working on the iWatch, a smartwatch accessory, but chances are slim that Apple would launch it at this event. However, we won?t rule it out completely as Apple is known to have a few surprises hidden up its sleeve and it could be CEO Tim Cook?s ?one more thing? moment.
Apple is yet to officially announce the launch date for the next iPhone.

Magnetization controlled at picosecond intervals
[unable to retrieve full-text content]A terahertz laser makes it possible to control a material's magnetization at a timescale of picoseconds (0.000,000,000,001 seconds). In their experiment, the researchers shone extremely short light pulses from the laser onto a magnetic material, where the magnetic moments - "elementary magnets" - were all aligned in parallel. The light pulse's magnetic field was able to deflect the magnetic moments from their idle state in such a way that they exactly followed the change of the laser's magnetic field with only a minor delay.

Book Review : The Attacking Ocean: The Past, Present, and Future of Rising Sea Levels by Brian Fagan
Review by Erin Wayman
By Brian Fagan
Web edition: August 9, 2013
Print edition: August 24, 2013; Vol.184 #4 (p. 30)
The threat of rising seas is not new. Since the last Ice Age began windingdown 15,000 years ago, the ocean has ascended 120 meters in a series of pulses. But when the world was thinly populated, small bands of hunter-gatherers could pick up and go when the sea surged. Now that hundreds of millions of people are settled in crowded coastal cities, the rising seas predicted for a warming world are more dangerous than ever, argues Fagan, an archaeologist.
Fagan chronicles the history of the climbing oceans and their influence on the development of early civilizations such as those of ancient Egypt and Mesopotamia. He also shows how modern societies from New Orleans to Shanghai continue to feel these effects. Without hyping the risks, Fagan provides solid geological, archaeological and historical evidence to support his arguments about what the future may hold.
Submerged land is but one hazard humanity faces as polar ice melts and oceans expand. Sea level rise will also exacerbate flooding from tsunamis and hurricanes. Wetlands, marshes and mangroves provide a natural barrier against these disasters by, for example, staving off erosion, Fagan notes. But humans are increasingly bulldozing this protection to make way for cities and industry. Of course, people have developed their own ways to fight back the seas, with levees, seawalls and the like. But these barriers aren?t foolproof, and sometimes they create their own environmental problems.
Fagan offers no simple solutions for impending sea level rise over the next century ? because there aren?t any. But he warns that society has to start tackling the problem now.

Military aircraft catches fire at Mogadishu airport
MOGADISHU |
MOGADISHU (Reuters) - An Ethiopian military aircraft carrying ammunition crash-landed at Mogadishu's international airport on Friday, bursting into flames and killing at least one crew member, airport staff and security officials said.
The plane got into trouble in the air and then missed the runway, crashing into the ground nearby.
Ethiopian troops are supporting Somalia's fight against al Qaeda-linked militants in the Horn of Africa country, although they are not part of an African Union (AU) peacekeeping force.
"We can hear explosions as it burns. It is burning like hell," said one security source at the airport shortly after the accident.
Yusuf Nur, an airport worker, said rounds of ammunition exploded in the fire.
A convoy of empty Somali military trucks had earlier been seen at the airport.
The fire, which was initially too intense for firefighting crews to tackle, was put out about two hours after the plane crashed. Witnesses said only a blackened shell remained.
Military aircraft regularly land at the city's airport, which also serves as the headquarters for the AU peacekeepers.
Authorities closed the airport, which has received a growing number of passenger flights over the past two years after African troops and Somali government forces flushed Islamist al Shabaab rebels from their bases in the capital.
Somalia's aviation record is among the worst on a continent which has a history of plane disasters. Until recently, the carcass of a Russian-made cargo plane lay tilted on its belly between the runway and passenger terminal of Mogadishu's airport.
Somalia is emerging from more than two decades of civil conflict. Security has improved in Mogadishu, which until mid-2011 was the frontline in the battle between government forces and militants, though the capital is still vulnerable to insurgent attacks.

Texas Man: I Was A Transgender NFL Cheerleader Before Detransitioning
Texas native Philip Porter spoke to HuffPost Live about his apparent decision to transition back to his birth sex (male) after living for 32 years as a transgender woman.
"I was born male, and always felt more female than male as a child growing up, to the point of before I could talk, [I thought] 'I should be over there with the girls in dresses. I'm over here wearing pants -- I don't understand it,'" he explained to host Alex Berg.
Growing up in the 1970s, Porter faced skepticism and disdain from doctors and psychologists. "Back then -- this was the '70s, we did not have Google, we did not have Internet -- it was very difficult to find, you know, a professional doctor or psychologist who could hear my story."
Finally, he met a doctor in Dallas, Tex. who helped him. "I was in his office the next day, an endocrinologist office the day after that, and just began my life living as a female. And did that very successfully and very happily for 32 years -- I was an NFL cheerleader and I was a topless dancer for many years."
But 32 years into his life as a woman, Porter began to consider living as a male. "I think part of it might be the mid-life crisis, where like you're starting to have the hot flashes and be very uncomfortable and it's like the hormones were having different effects on me. I just said 'Ok, I'll stop taking these for awhile but it's not going to change back after 34 years of taking them.'"
"And after that, it just started happening," he continued. "After about 6 months to 9 months being off of them, 'you know, you never gave yourself a chance to sort of live as a male. What would that be like?' And it kind of was something in my mind that started as just a little thought that kind of like snowballed. And you know, I mean that's just kind of how it happened."

This Hilarious Secret Behind Jony Ive's Inspiration for iOS 7
iOS 7 is just so colorful! It's so light! It's so fun! But not only that, the colors all blend together in a beautiful watercolor effect. It's like a pastel psychedelic trip. It's like seeing the palette of an artist obsessed with Easter. I wonder where Jony Ive got the idea for that color scheme. I wonder what his inspiration was. Wonder no more.

Verve energy drink drives Vemma Nutrition sales
DBR Staff Writer
Published 08 August 2013
Published 08 August 2013
Vemma Nutrition, a US-based liquid nutrition company, has reported sales of $20m per month in July 2013, driven by its Verve healthy energy drink brand.
The company took seven years to reach the $10m monthly sales mark in July 2012.
Vemma Nutrition has also reached 30,000 monthly customer and Brand Partner enrollments in July 2013.
Verve healthy energy drink brand, including the release of Verve Bold in January 2013, has given a boost to the sales selling over four million cans in the first five months.
Vemma marketing and brand development executive vice president Mark Patterson that the company will enter into coffee and tea markets in 2014.
"And there's the upcoming launch in January of Vemma's new Chris Powell Bod-e? Shake in a ready-to-drink (RTD) can. Verve has taught Vemma an important lesson -- RTD is critical for massive acceptance and consumption," Patterson added.
Vemma founder and CEO BK Boreyko said: "We expect sales will continue to increase as school gets back into session, and with the new Verve ParTea?, a flavored iced tea energy drink which will be released this fall, followed by Verve MoJoe?, a vanilla latte flavored iced coffee, in January 2014."

Omari Hardwick ?Fixes? Gabrielle Union In ?Being Mary Jane? Sneak Peek [VIDEO]
In this seductive sneak peek at the next season of BET?s ?Being Mary Jane,? Andre (played by Omari Hardwick) is having a conversation with Mary Jane (Gabrielle Union) when she calls him out on a promise to fix her pool that he hasn?t made good on.
RELATED: Omari Hardwick On Keeping His Cool Around Hot Women
In the pilot Mary Jane kicks Andre to the curb after finding out that he?s married and confesses their affair to his wife. So we?re assuming this is one of their first conversations after the cat is let out of the bag.
While the whole double entendre of being the fix it man,?diving in? to ??screw in a light bulb? and asking if she ?needs anything else done? is a tad cliche, the dialogue sets up a rather steamy love scene that may or may not make it past the censors.

Genome of HeLa cell line first published by G3: Genes|Genomes|Genetics now released to scientists
BETHESDA, MD -- The first study to sequence and analyze the entire genome of a HeLa cell line, along with access to its sequence data, has been published today (Wednesday, August 7) in its final version, by G3: Genes|Genomes|Genetics, an open-access, scientific journal of the Genetics Society of America.
The article, "The Genomic and Transcriptomic Landscape of a HeLa Cell Line," by Landry et al., was authored by scientists at the European Molecular Biology Laboratory (EMBL) in Heidelberg, Germany, and was published in an early online version March 11, 2013.
Genomic data from the HeLa cell line are also being released with the final version of the paper as a result of discussions between leaders of the National Institutes of Health (NIH) and relatives of Henrietta Lacks, from whose cervical tumor the original HeLa cell line was derived prior to her death in 1951. The genomic data will now be available to scientists via the NCBI's Database of Genotypes and Phenotypes (dbGaP).
In direct response to the concerns of the Lacks family that the privacy of their genetic information might be affected by the availability of the HeLa genome sequence data published in G3, the EMBL scientists voluntarily removed the HeLa cell line sequence data from public access, and offered to work with the family towards a mutually acceptable solution. NIH Director Francis S. Collins, M.D., Ph.D., and NIH Deputy Director for Science, Outreach, and Policy Kathy L. Hudson, Ph.D., met several times with representatives of the Lacks family, and came to a mutual understanding to allow biomedical researchers controlled access to the data. Dr. Collins and Dr. Hudson describe their discussions with the Lacks family in a Comment published in this week's edition of the journal Nature.
Since their isolation in 1951, HeLa cells have been the most widely used human cell line in research. They have become a valuable resource for biologists, enabling momentous scientific breakthroughs including the development of the polio vaccine the Nobel Prize winning studies defining the role of telomerase in aging, and research on the causative role of human papillomavirus (HPV) in some types of cervical cancer. The latter discovery spurred the development of an HPV vaccine to prevent certain types of cervical cancer from occurring. In fact, Ms. Lacks' death was caused by cervical cancer.
The advent of genomics and rapid sequencing techniques has seen HeLa cells used in numerous large-scale studies of gene function and expression. Yet, "these studies using HeLa cells had to rely on information from the 'reference' sequence produced by the Human Genome Project, even though there was evidence that the genomes of HeLa cell lines were probably quite different," said Lars Steinmetz, Ph.D., who led the G3 study.
Dr. Steinmetz and his team found the genome of the HeLa cell line that they sequenced differs dramatically from a normal human genome sequence. These differences include widespread sequence variation, extra copies of genes, and massive, complex rearrangements.
Because the dataset now will be available to the scientific community, researchers will be able to account for these differences when designing and interpreting experiments using this HeLa cell line. The genomic particularities of HeLa cells relate to their origin from an aggressive cancer and subsequent cultivation in laboratories for decades, both of which cause considerable genomic alterations.
"Understanding the unique nature of the HeLa genome is important for guiding future studies with these cells," explained Brenda Andrews, Ph.D., editor-in-chief of G3. "This paper and the genomic data it includes provide an important resource for the scientific community, especially with the increasing number of studies that require genome sequence information for accurate design and interpretation."
"We are very happy that G3 is able to publish these findings, and to make this dataset available to the scientific community," says Adam Fagen, Ph.D., executive director of the Genetics Society of America. "The Lacks family has taken an important step towards ensuring HeLa cells continue to catalyze important advances in biomedical research."
Genomics studies like those commonly conducted with HeLa cells play an instrumental role in revealing how variation in genome sequence and function can lead to disease. "Progress in genomic research has already begun to transform modern medicine," said Tracey DePellegrin, executive editor of G3, which, like its sister journal GENETICS also published by Genetics Society of America, promotes full data sharing and dissemination for scientific reseachers, "and this progress is contingent on scientists being able to access the genomic sequences, now available through dbGaP.
"As soon as they learned about the Lacks family's concerns, the authors of the G3 paper voluntarily removed the sequence data from public access. We supported our authors' response, in particular as a resolution to the issues became actively discussed by NIH officials and the Lacks family," she added.
The early publication of the G3 study sparked dialogue among scientists, bioethicists and the public concerning the handling of genomic data. Such conversations become critical as technological advances make personal genome sequencing increasingly affordable and commonplace. Indeed, GSA is initiating discussions with other scientists, ethicists and members of the public to refine strategies to manage genomic data in socially conscious ways that foster progress in scientific research.
"Although NIH played an essential role in the discussions with the Lacks family about the use of HeLa cells, we all need to think about how we approach issues that arise as science moves forward, balancing privacy concerns with advances in research, and the ways policy can be updated to reflect these complexities," added Dr. Fagen. "Everyone including scientists, the public, policymakers, our health care system, and research funders has a stake in the outcome.

Canadians can't risk meagre promise of Energy East pipeline
Imagine that you step out your door for the morning commute, but your street is flooded. Not with water, but with bitumen from the tar sands.
This is precisely what happened with Exxon's Pegasus pipeline when it spilled over one million litres of tar sands crude into the Arkansas suburb of Mayflower earlier this year. And it's the potential future facing communities along the route of TransCanada's recently announced Energy East pipeline, if the plan moves ahead. The project would see oil, including diluted bitumen, transported from Alberta's tar sands to Quebec and Atlantic Canada.
Pipeline safety in question
"What I have documented from the pipeline industry is that the mix of politics and commercial interests has resulted in false public claims of exceptional industry practice when the reality is that industry struggles to comply with code and regulation." This recent testimony at Senate committee from a former TransCanada engineer who made headlines last year raises serious questions about TransCanada's promises.
Tar sands crude (diluted bitumen) is unlike conventional oil. It is thick, requiring dilution with toxic chemicals. The devastating spill of over 3.8 million litres of tar sands crude in the Kalamazoo River in Michigan underscores how tar sands spills are far more devastating. Conventional cleanup methods haven't been able to address the heavy crude which sunk to the bottom of the river bed. Three years and over $800 million later, the river is still polluted.
The impacts of a spill in the Bay of Fundy could be even worse, given the strong tides.?
The Energy East project would see the conversion of an existing gas pipeline, the Mainline, from Saskatchewan to Qu?bec, to carry crude oil. The Pegasus pipeline that flooded the streets of Mayflower was also designed to carry a lighter substance.
According to a study by the National Petroleum Council for the U.S. Department of Energy, "pipelines operating outside of their design parameters such as those carrying commodities for which they were not initially designed, or high flow pipelines, are at the greatest risk of integrity issues in the future due to the nature of their operation."
These are the risks communities along Energy East are being asked to bear.
Energy and job security claims dubious?
While there has been a lot of talk about Atlantic energy security, this crude will actually go to the highest bidder and the U.S., China, India and Europe are in line. This would threaten the Gulf of St. Lawrence and the Bay of Fundy with supertanker traffic carrying diluted bitumen. Additionally, just because crude may be refined in Qu?bec and New Brunswick does not mean that it will be consumed there. The majority of oil produced in Atlantic Canada is exported -- how can we trust that this will be different?
We need to look critically at job promises for this project. Studies have shown that TransCanada's Keystone XL job promises have basically been a smokescreen to win approval of an unwanted pipeline. TransCanada claimed Keystone "would create 20,000 jobs". However, President Obama says construction of Keystone XL would create 2,000 short-term jobs and only 50-100 long term jobs.
Generating jobs that support families in the Atlantic region and across the country is absolutely crucial, but this doesn't mean we shouldn't question the quality and types of jobs being presented and the environmental and social toll these jobs will have. The adverse long-term effects a spill would have on peoples' livelihoods need to be considered too, particularly related to fisheries jobs in the Bay of Fundy and Passamaquoddy Bay.
Energy East would facilitate Tar Sands expansion
With members, supporters and allies along the pipeline route, the Council of Canadians intends to build awareness and work with those who would be directly impacted by the project. We will be present at upcoming TransCanada project open houses along the pipeline route, intend on participating in the forthcoming National Energy Board proceedings and support local opposition that has already emerged.
Energy East and other pipelines are being pushed through to lock in expansion of the tar sands. Since people are increasingly aware of the dangers tar sands bring to their communities, it is no surprise that people are raising their voices to stop it.?
We keep hearing that this pipeline is about energy security, but real energy security means prioritizing a transition off of fossil fuels, particularly carbon intensive crude like the tar sands. There is an abundance of potential for generating decent, green jobs in provinces like New Brunswick. These jobs, such as work improving building's energy efficiency, can provide for families while reducing emissions. TransCanada's Energy East pipeline however, is part of the problem, not the solution.

Injuries after California power plant razed
By Kevin Murphy
(Reuters) - One man lost part of his leg and four other people were injured by flying debris as they watched the planned implosion of an abandoned power plant in Bakersfield, California, early on Saturday morning, officials said.
The 43-year-old "suffered a traumatic partial amputation of one leg and major injuries to the other," the Bakersfield Police Department said in a statement.
Shrapnel from the blast also hit four other spectators, causing minor injuries, said Kern County Fire Department fire engineer Leland Davis, adding there were at least 1,000 onlookers.
Police said only two other spectators were injured and had not revised their tally.
One officer along the east perimeter heard screams for help at the 6 a.m. implosion, said police, who were on scene helping to control traffic and crowds.
The boiler facility, which belonged to Pacific Gas and Electric Company and was decommissioned in 1986, had two towers 140 feet tall and four 200,000-gallon (757?,082-liter) empty water tanks, company spokesman Denny Boyles said.
It was being removed so the property could be cleared for sale under an agreement with the city of Bakersfield, he said.
Demolition subcontractors worked with police to establish a 1,000-foot (305-meter) perimeter beyond which a crowd had gathered to observe the demolition, Boyles said. He said the injured people were apparently outside the perimeter.
"Our thoughts and prayers are with those who were injured during the demolition," Boyles said, adding that the company and subcontractors are cooperating with local authorities investigating what went wrong.
The man with the leg injuries was taken to a local hospital and then to Fresno, California, for further treatment, police said. The four others who were injured received treatment at the scene, Davis said.

Big night for Lochte, Magnussen, US golden girls
BARCELONA, Spain (AP) ? Ryan Lochte and James Magnussen are back on top at the world swimming championships.
Missy Franklin and Katie Ledecky just keep on winning.
After a disappointing start to the meet, Lochte looked more like himself Thursday night, pulling away to capture gold in the 200-meter individual medley.
Magnussen, who was viewed as a flop despite a silver medal at the London Olympics, rallied to win the 100 freestyle with a furious finishing kick, edging Americans Jimmy Feigen and Nathan Adrian.
But the Americans came through in the final event of the night.
No surprise there. Not with Franklin and Ledecky leading the U.S. team in the 4x200 free relay.
Ledecky put the Americans ahead at the start, and Franklin zipped away with a dominant anchor leg to win in 7 minutes, 45.14 seconds.
The 18-year-old Franklin is now 4 for 4 in Barcelona, with three events to go. Ledecky, only 16 and getting ready for her junior year of high school, is 3 for 3 with one race left.
No matter what, they will go down as two of the biggest stars of this meet.
Lochte barely celebrated after his race, letting out a deep breath as he squinted to see his winning time ? 1:54.98. Japan's Kosuke Hagino claimed the silver, more than a second behind, and Brazil's Thiago Pereira took bronze.
"The first two days I wasn't myself," Lochte said. "I was too worried about the outcome of each race, about finishing first, about my times, and that's not me. I am a swimmer who is really relaxed and goes out there to have fun."
Magnussen was certainly having fun after winning the sport's glamour event ? a victory he was denied last summer. The Australian swimmer known as "The Missile" hopped on the lane rope, flexing his muscles for the crowd while the fans from Down Under shouted "Oi! Oi! Oi!"
"It was really emotional," Magnussen said. "That last sort of 15 meters I really used the last 12 months of experiences that I've gone through, and I was really aggressive toward the wall at the end. I'm just stoked that I got there."
Russia's Vladimir Morozov, who does much of his training in Southern California, was the leader at the turn, just ahead of Adrian, the Olympic champion.
Magnussen was nearly a second off the pace, but he powered through the water on the return lap to win in 47.71. Feigen also relied on a strong finish to get the silver in 47.82, leaving Adrian to settle for the bronze at 47.84. Morozov faded to fifth.
At the Olympics, Magnussen was a big favorite in the 100 free, but Adrian edged him for the gold medal by a hundredth of a second ? the smallest margin possible in swimming. The Missile also failed to make the final of the 50 free, becoming one of the symbols of an underachieving Australian men's team that didn't win even one gold medal.
The Aussie men already have two in Barcelona: Magnussen and Christian Sprenger in the 100 breaststroke.
Magnussen was asked if beating Adrian was especially sweet after what happened in London.
"No," he said. "You know, if Adrian wasn't such a nice guy, it might be. You just can't hate him because he's so nice. I was just doing it for myself tonight."
The Americans were happy with their showing, especially Feigen. While Magnussen celebrated, a smiling Adrian put his arm around his teammate, who took the bulk of the blame for the U.S. settling for silver in the 4x100 freestyle relay. Despite a lack of international experience, Feigen was put on the anchor leg ? and couldn't hold on as France rallied for the victory.
Feigen was second again in the 100 free, but this time it felt more like a win.
"I started off a little shaky this whole worlds thing," he said. "I think it's coming together in the end."
Adrian knew it would be hard to hold off Magnussen.
"He's just an incredible competitor, and he's actually brought an entire new level to the 100 freestyle," Adrian said. "So it's a bummer, because without him we would be 1-2, but it's a good thing for the sport. It's exciting moving forward."
Lochte, who took a long break after London and cut back his training to work on a reality TV show, hardly looked in peak form while swimming the second leg of that 4x100 relay and laboring to a fourth-place finish in the 200 freestyle.
Then, he had a bit of an epiphany. Lochte said he had spent too much time worrying about results instead of just having fun. Sure, he wasn't in the best of condition, but he figured his racing skill would come through if he just relaxed a bit.
Well, he had every reason to scream "Jeah!" ? his nonsensical catchphrase ? after a dominating win in the 200 IM, a race he lost to Michael Phelps at last summer's Olympics.
Lochte trailed Pereira at the midway point, but he turned it on during the breaststroke leg and pulled away on the freestyle finish, gliding across the water to win by about a body length, 1.31 ahead of Hagino.
It was the 13th world championship gold of Lochte's career, his 21st medal overall.
He returned about 80 minutes later for the semifinals of the 200 backstroke. Lochte advanced to the final with the second-fastest time, trailing only teammate and reigning Olympic champion Tyler Clary.
In the relay, Ledecky led France's Camille Muffat at the first exchange, but the U.S. slipped back to second ? first behind the French, then Australia ? as Shannon Vreeland and Karlee Bispo took over for the middle legs.
But the U.S. was close enough when Franklin dove in for the final 200. She zipped by Australia's Alicia Coutts and won the gold easily. Australia settled for silver in 7:47.08, while France took the bronze in 7:48.43.
In the biggest surprise of the night, Denmark's Rikke Pedersen set a world record in the semifinals of the women's 200 breaststroke. She touched in 2:19.11, breaking the mark of 2:19.59 set by American Rebecca Soni at the London Games.
Soni is taking the year off but traveled to Barcelona for the championships.
China added to its medal haul with a pair of golds and a silver. Liu Zige won the women's 200 butterfly, edging the crowd favorite, Spain's Mireia Belmonte. Hungary's Katinka Hosszu took the bronze. Cammile Adams of the U.S. was seventh.
The Chinese went 1-2 in the 50 back, an event dropped by Franklin to focus on her other events. Zhao Jing won gold, with teammate Fu Yuanhui claiming the silver. The bronze went to Japan's Aya Terakawa. American Rachel Bootsma finished seventh.

Japanese vehicle delivers new hardware for NASA's Robotic Refueling Mission
Public release date: 2-Aug-2013[ | E-mail |
Share ] Contact: Rob Gutro
Robert.j.gutro@nasa.gov
301-286-4044
NASA/Goddard Space Flight Center
It may be called the Robotic Refueling Mission (RRM), but NASA's RRM was built to demonstrate much more than the clever ways space robots can fill up satellites.
With the launch of new hardware to the International Space Station on Aug. 3, RRM recently named a "Top Exploration Technology Application From the International Space Station in 2012" will be outfitted to practice a new set of satellite-servicing activities.
New Hardware for a New Era of Satellite-Servicing Demonstrations
Earlier in 2013, RRM demonstrated remotely controlled robots using today's technology could refuel satellites not designed to be serviced. RRM tests from January 14 to 25 culminated in a first-of-its-kind robotic fluid transfer.
Following the success of completing this namesake task, in 2014 RRM will demonstrate how space robots can replenish cryogen (a type of refrigerant) in the instruments of legacy satellitesexisting, orbiting spacecraft not originally designed to be serviced.
"Just like robotic refueling, there were a lot of folks who said that this simply couldn't be done," says Benjamin Reed, deputy project manager of the Satellite Servicing Capabilities Office (SSCO) at NASA's Goddard Space Flight Center in Greenbelt, Md.
"But that's the whole point of the RRM demonstrations and the beauty of being able to execute them on such an extraordinary test bed as the space station. RRM is allowing us to show that the robotic satellite-servicing tools, technologies and techniques are mature and ready, because we've proven them on orbit."
Delivery to Space Station and Installation
New hardware deliveries to the space station will outfit the RRM module for this upcoming set of operations.
The Japanese HTV cargo vehicle, currently scheduled to launch on Aug. 3, will deliver a new task board and the RRM On-orbit Transfer Cage (ROTC), an original device designed to transfer hardware outside of the space station. Astronauts will mount the ROTC on the sliding table within the Japanese airlock and then install the task board onto the ROTC, giving the Canadian Dextre robot an easy platform from which to retrieve and subsequently install the new hardware.
A second shipment in 2014 will bring a second task board and a new device called the Visual Inspection Poseable Invertebrate Robot (VIPIR). This SSCO-built borescope inspection tool provides a set of eyes for internal satellite repair jobs. Both also will be transferred and installed on RRM via the Japanese airlock, ROTC and Dextre.
With the help of the twin-armed Dextre robot, the newly installed RRM task boards, and the RRM tools, the RRM team will then work its way through intermediate steps leading up to cryogen replenishment. After retrofitting valves with new hardware, peering into dark places with the aid of VIPIR and creating a pressure-tight seal, the RRM and Dextre duo will stop short of actual cryogen transfer for this round of tasks.
RRM Phase 2 operations are scheduled to begin in 2014. Initial activities to demonstrate this in-orbit capability cutting wires and removing caps were completed in 2012 with the aid of the original RRM tools and activity boards.
Expanding Capabilities and Fleet Flexibility in Space
Cryogenic fluids are used on the ground and in space to make very sensitive cameras work better. However, in time this extremely cold substance leaks out, and the camera no longer performs well. Robotically replenishing these reserves, explains Reed, would allow spacecraft instruments to last past their expiration date and ultimately permit satellites to perform longer.
"It's all about expanding options for fleet operators, in both the government and the commercial sectors," Reed said. "Instead of retiring an aging observatory or spacecraft and perhaps launching a new, costly, one [operators] could choose to extend their lives by calling on a future cryogen-toting space tow truck. The RRM demonstrations are an important step to eventually enabling this capability."
Preparing for a Servicing-Enabled Future
"Since its launch to the ISS in 2011 on the last shuttle mission, RRM has been steadily practicing robotic satellite-servicing activities on orbit," says Jill McGuire, RRM project manager at SSCO. "A joint effort with the Canadian Space Agency, RRM uses the space station as a test bed for technology research and development."
On July 17, RRM was named a "Top Exploration Technology Application from the International Space Station in 2012" at the second international ISS Research and Development Conference in Denver. McGuire accepted on behalf of the team.
NASA developed RRM to demonstrate how remotely-operated robot mechanics could extend the lives of the hundreds of satellites residing in geosynchronous-Earth orbit (GEO). Costly assets traveling about 22,000 miles above Earth, GEO spacecraft deliver such essential services as weather reports, cell phone communications, television broadcasts, government communications and air traffic management. Servicing capabilities could greatly expand the options for government and commercial fleet operators in the future. They could potentially deliver satellite owners significant savings in spacecraft replacement and launch costs.
NASA continues to test capabilities for a new robotic servicing frontier. In conjunction with RRM, the SSCO team has been studying a conceptual servicing mission while building the necessary technologies, including an autonomous rendezvous and capture system, a propellant transfer system and specialized algorithms to orchestrate and synchronize satellite-servicing operations.
