How Would You Like Your Assistant -- Human or Robotic?

Apr. 29, 2013 ? Roboticists are currently developing machines that have the potential to help patients with caregiving tasks, such as housework, feeding and walking. But before they reach the care recipients, assistive robots will first have to be accepted by healthcare providers such as nurses and nursing assistants. Based on a Georgia Institute of Technology study, it appears that they may be welcomed with open arms depending on the tasks at hand.

More than half of healthcare providers interviewed said that if they were offered an assistant, they preferred it to be a robotic helper rather than a human. However, they don't want robots to help with everything. They were very particular about what they wanted a robot to do, and not do. Instrumental activities of daily living (IDALs), such as helping with housework and reminding patients when to take medication, were acceptable. But activities daily living (ADL) tasks, especially those involving direct, physical interactions such as bathing, getting dressed and feeding people, were considered better for human assistants.

The findings will be presented April 27- May 2 at the ACM SIGCHI Conference on Human Factors in Computing Systems in Paris, France.

"One open question was whether healthcare providers would reject the idea of robotic assistants out of fear that the robots would replace them in the workplace," said Tracy Mitzner, one of the study's leaders and the associate director of Georgia Tech's Human Factors and Aging Laboratory. "This doesn't appear to be a significant concern. In fact, the professional caregivers we interviewed viewed robots as a way to improve their jobs and the care they're able to give patients."

For instance, nurses preferred a robot assistant that could help them lift patients from a bed to a chair. They also indicated that robotic assistants could be helpful with some medical tasks such as checking vitals.

"Robots aren't being designed to eliminate people. Instead, they can help reduce physical demands and workloads," Mitzner said. "Hopefully, our study helps create guidelines for developers and facilitates deployment into the healthcare industry. It doesn't make sense to build robots that won't be accepted by the end user."

This study complements the lab's prior research that found older people are generally willing to accept help from robots. Much like the current research, their preferences depended on the task. Participants said they preferred robotic help over human help for chores such as cleaning the kitchen and doing laundry. Getting dressed and suggesting medication were tasks viewed as better suited for human assistants.

Patterned hearts: Bioengineers create rubber-like material bearing micropatterns for stronger, more elastic hearts

Apr. 29, 2013 ? A team of bioengineers at Brigham and Women's Hospital (BWH) is the first to report creating artificial heart tissue that closely mimics the functions of natural heart tissue through the use of human-based materials. Their work will advance how clinicians treat the damaging effects caused by heart disease, the leading cause of death in the United States.

"Scientists and clinicians alike are eager for new approaches to creating artificial heart tissues that resemble the native tissues as much as possible, in terms of physical properties and function," said Nasim Annabi, PhD, BWH Renal Division, first study author. "Current biomaterials used to repair hearts after a heart attack and other cardiovascular events lack suitable functionality and strength. We are introducing an alternative that has the mechanical properties and functions of native heart tissue."

The study was published online on April 26, 2013 in Advanced Functional Materials.

The researchers created MeTro gel-an advanced rubber-like material made from tropoelastin, the protein in human tissues that makes them elastic. The gel was then combined with microfabrication techniques to generate gels containing well-defined micropatterns for high elasticity.

The researchers then used these highly elastic micropatterned gels to create heart tissue that contained beating heart muscle cells.

"The micropatterned gel provides elastic mechanical support of natural heart muscle tissue as demonstrated by its ability to promote attachment, spreading, alignment, function and communication of heart muscle cells," said Annabi.

The researchers state that MeTro gel will provide a model for future studies on how heart cells behave. Moreover, the work lays the foundation for creating more elaborate 3D versions of heart tissue that will contain vascular networks.

"This can be achieved by assembling tandem layers of micropatterned MeTro gels seeded with heart muscles cells in different layers," said Ali Khademhosseini, PhD, BWH Division of Biomedical Engineering, co-senior study author. "As we continue to move forward with finding better ways to mend a broken heart, we hope the biomaterials we engineer will allow us to successfully address the limitations of current artificial tissues."

This research was supported by the National Institutes of Health (HL092836, DE019024, EB012597, AR057837, DE021468, HL099073, EB008392); National Health and Medical Research Council; CRC for Polymers; BHP-Billiton Fulbright Scholarship; National Science Foundation; Office of Naval Research Young National Investigator Award; Presidential Early Career Award for Scientists and Engineers; Australian Research Council; and Australian Defense Health Foundation and National Health and Medical Research Council.

Yen tumbles on aggressive BOJ; U.S. jobs weigh on stocks

By Wayne Cole

SYDNEY (Reuters) - The yen resumed its precipitous slide early Monday to hit fresh lows against a host of major currencies as reports the Bank of Japan would begin buying longer-dated bonds immediately underlined its determination to beat deflation.

Asia-Pacific stock markets were set to open slightly lower, weighed on by a weaker-than-expected U.S. employment reading which fuelled concerns that the recovery in the world's largest economy may be losing steam.

The U.S. dollar jumped a full yen in early Asian trading to hit 98.78 yen, the highest since June 2009. The euro climbed as far as 128.32 yen, its highest since January 2010.

Dealers were impressed by a Nikkei report the central bank would this week buy 1.2 trillion yen of government bonds with a maturity of over five years, showing a sense of urgency alien to the BOJ of old.

Yields on benchmark 10-year Japanese government bonds sank to a record low of 0.315 percent on Friday.

Analysts assume the flood of new money will be partly used by Japanese investors to buy higher yielding assets abroad, so putting downward pressure on the yen.

"We have re-established a broad basket of JPY shorts in light of last week's BOJ aggressive actions," wrote analysts from JPMorgan in a client report. "Radical monetary measures were needed to re-invigorate the downtrend in the yen, and on this front the BOJ has over delivered."

JPMorgan had re-established long positions in USD/JPY and also favored the Australian dollar and Brazilian real as carry trades against the yen.

The Aussie dollar soared to 102.32 yen, the highest since July 2008.

Australian stocks were set to open marginally lower, while New Zealand's market <.nz50> fell 0.1 percent in early trade, out-performing global stock market losses following Friday's U.S. non-farm payrolls report.

U.S. employers hired at the slowest pace in nine months in March, adding just 88,000 nonfarm jobs, the Labor Department said, below an expected 200,000. The jobless rate ticked a tenth of a point lower to 7.6 percent, but the drop was largely due to people dropping out of the work force.

The soft jobs report also weighed on energy and industrial metals, with Brent crude futures hovering near an eight-month low hit on Friday and copper also in sight of its lowest since August 2012.

U.S. evangelical pastor's son commits suicide

(Reuters) - The son of popular American evangelical pastor Rick Warren has committed suicide after a life-long struggle with depression and mental illness, according to a letter sent by Warren and his wife, Kay, to the staff of his Saddleback Valley Community Church.

Matthew Warren, 27, took his own life in "a momentary wave of despair at his home" after a "fun evening" with his parents, Warren said in a statement on Saturday.

"Kay and I are overwhelmed by your love, prayers, and kind words," Warren wrote on his Facebook page on Sunday.

Along with leading the Saddleback Church based in Lake Forest, California, Warren is author of the best-selling book "The Purpose Driven Life."

He delivered an invocation at President Barack Obama's first inauguration in January 2009.

Warren described his son as an "incredibly kind, gentle, and compassionate man. He had a brilliant intellect and a gift for sensing who was most in pain or most uncomfortable in a room."

Warren said in his statement that all his life, his son had struggled with mental illness, depression and suicidal thoughts.

"In spite of America's best doctors, meds, counselors, and prayers for healing, the torture of mental illness never subsided," he said.

The Orange County, California, Coroner's office responded to Warren's home in Mission Viejo at 10 a.m. on Friday, according to the agency's records. The City News Service in Los Angeles said Warren was found dead of a self-inflicted gun-shot wound.

Saddleback, one of the largest evangelical churches in the United States, is affiliated with the Southern Baptist Convention. About 20,000 people attend weekly services at the main campus in Lake Forest, California, and at seven other churches located throughout southern California.

Cuban ballet defectors make moves in Miami

By David Adams

MIAMI (Reuters) - Six dancers who defected last month from the National Ballet of Cuba, one of the country's proudest and most prestigious institutions, auditioned at a Miami ballet group on Thursday.

"They are so talented and we are thrilled to see them," said Pedro Pablo Pena, founder of the Cuban Classical Ballet of Miami, a nonprofit dance organization.

After an intense two-hour workout, the dancers explained that they were looking to advance their careers outside communist-led Cuba, where dancers enjoy privileged lives but earn modest salaries of $10 to $30 a month plus bonuses for foreign tours.

"Our goal is to train hard to achieve our dream of dancing and helping our families economically in Cuba," said Annie Ruiz Diaz, 24, who began dancing in Cuba at age 6 and had been with the National Ballet for almost seven years.

The defectors are staying with friends and relatives in Miami until they can find work.

"We expect to put on some events with them for the community here, but I don't have the budget to employ them full-time, unfortunately," said Pena, the host of the audition.

"But they are talented and I imagine they will find spaces in companies here in the United States," said Pena, a former dancer who came to Miami from Cuba in 1980.

The National Ballet of Cuba confirmed on Wednesday that seven members of the group had abandoned the company while touring in Mexico last month.

The dancers said they made their way to the U.S. border, where they were allowed entry under the Cuban Adjustment Act, which grants special immigration privileges to Cuban exiles as well as financial benefits to help them get on their feet.

One of the dancers stayed behind in Mexico with friends, they said.

CUBA CRITICIZES U.S. LAW

There was no mention of the defections in the state-run media in Cuba, which has seen periodic defections of artists and athletes since Fidel Castro's revolution in 1959.

Speaking at an event in Washington, the chief of the Cuba Interests Section, Jose Cabanas, blamed the defections on the Cuban Adjustment Act because he said it makes it easy for any Cuban to enter the United States.

"The press is going after the defections - but the real questions are related to those pieces of legislation that create those situations that are nice for the cameras and the microphones," he said.

The dancers - five men and two women between the ages of 20 and 24 - quit the company at the end of a nine-day tour performing "Giselle" in Mexico's Yucatan Peninsula.

After a night of emotional farewells with fellow dancers, they said they left their hotel before dawn on March 25 and headed by bus and car to the U.S. border.

"There were a lot of tears. We loved dancing for the company and we have a lot of friends," said Arianni Martin, a 20-year-old soloist who had been with the company for two years and was earning $10 a month.

She said she was paid $225 for the Yucatan tour.

The Cuban national ballet, known for its classical style and for producing world-class dancers, regularly makes international tours.

Over the years, many of its dancers have defected and joined other companies abroad, often saying they want to explore contemporary dance forms and build more lucrative careers outside Cuba.

Others have been allowed to leave Cuba on contract to foreign ballet companies. They include Carlos Acosta with the Royal Ballet in London and Jose Manuel Carreno, who retired in 2011 as a principal dancer at the American Ballet Theatre in New York.

"Artistically I felt stagnant and economically I couldn't help my family," said Martin.

Her parents have government jobs - her father drives a delivery truck and her mother looks after the elderly. But Martin said she was not worried about reprisals against her family.

"So many dancers leave, and I think the company understands that's part of the risk of our touring abroad," she said.

ALICIA ALONSO'S BALLET

Cuban ballet legend Alicia Alonso founded the National Ballet of Cuba in 1948 and, at the age of 91, despite being nearly blind, continues as its artistic director.

Cuba provides free training to thousands of young dancers around the country from the age of 9, with the elite graduating to the National Ballet.

The company has struggled financially in recent years and now accepts fee-paying dance students from abroad.

The school's Havana headquarters, located in a colonial-era former palace, is also undergoing expensive repairs after parts of the ceiling collapsed.

The 120-strong company is likely to overcome the loss of seven members, said Octavio Roca, a Cuban-American philosophy teacher and author of the book, "Cuban Ballet."

"It hurts them of course, but they have a great farm system, so much young talent coming up. It's an incredible program," he said.

Apple Brazil makes substantial price cuts on iPhone 4 and iPhone 4S

Apple Brazil cuts prices on iPhone 4 and iPhone 4S

It might not have the trademark, but that hasn't stopped Apple shaving the cost of its entry-level iPhone 4 and 4S' to something closer to its price tag in North America. The 16GB iPhone 4S is now R$1,699 ($840), down from R$1,999, while the 8GB flavor of the iPhone 4 now rings in at R$1,099 ($544), reduced from R$1,499. According to O Globo, if you're willing to pay upfront in full (and by phone) you can even snatch an extra 10 percent off both. Otherwise, Brazilians will need to visit the online store to lay claim to the heavily-discounted handsets.

After Being Acquired By Google, Shipping Service Bufferbox Is Preparing A Bay Area Launch

2200969789_0a86950c8d_zBufferbox, the Y Combinator company based in Canada that aimed to fix all of the issues that we have with receiving packages, has started to tease out a San Francisco Bay Area launch. Google acquired the company for a rumored $17 million to $25 million back in November?with little or no discussion about the future plans for the product. It’s clear that this could be a huge part of Google’s recently announced ‘Shopping Express’ same-day delivery service. Want to pick something up from a Bufferbox instead of having it brought directly to you? No problem. Middle men are completely cut out. The service has been operating without interruption in the greater Toronto area, but this area of California would be more than just a test. We know that the current package delivery system here in the United States is broken, and the government-funded postal service is pulling back on things like…delivering on the weekend. Google is clearly getting into the space in a big way, and the tease on Bufferbox’s homepage, which probably picked up my browsing location, says it all: Right now, all you can do is give them your email address to “pre-register,” which gives Google a pretty good idea of the demand for the service. We’ve reached out to Google for more details, and will update if we do hear something more. This is definitely a space that we’re tracking closely, as another Y Combinator company doing something similar, Swapbox, recently launched in the Bay Area. Instead of shipping something to your address, it goes to your Bufferbox, so that you can pick it up whenever you like. Right now, when you have something shipped to you and miss the delivery person, you’re pretty much screwed and have to wait for them to come back, or worse, go pick up the item yourself at a factory. If your package does get delivered, it just sits on your doorstep, being gawked at by your neighbors. This is a bit similar to the notion of having a P.O. box, but it isn’t a box or address that is static. You can get deliveries to any of the locations that you want. Additionally, these things should be available in the open, so you can get your packages at any time of the day or night, rather than before the post office closes. As we know, testing things out in the

Putting larval cobia to the acid test

Wednesday, April 3, 2013

Ocean acidification, which occurs as CO2 is absorbed by the world's oceans, is a source of concern for marine scientists worldwide. Studies on coral, mollusks, and other ocean denizens are helping to paint a picture of what the future might entail for specific species, should carbon emissions continue to increase.

In a new study published in Global Change Biology, University of Miami (UM) Rosenstiel School of Marine & Atmospheric Science researchers Sean Bignami, Su Sponaugle, and Robert Cowen are the first to study the effects of acidification on the larvae of cobia (Rachycentron canandum). Cobia are large tropical fish that spawn in pelagic waters, highly mobile as they mature, and a popular species among recreational anglers.

The team reared cobia in tanks with different levels of CO2 saturation looking for effects on growth, development, otolith (ear stone) formation, swimming ability, and activity level during the vulnerable larval stage of these fish. They found that cobia showed remarkable resistance to end-of-century acidification scenarios in terms of growth, development, and activity. However, more extreme acidification scenarios caused reduced larval size and a 2-3 day delay in their development. The study also reports a significant increase in otolith size at the most mild acidification conditions reported to date.

"The larval period is a critical stage in the marine fish lifecycle and the ability of cobia larvae to withstand 'business-as-usual' scenarios of ocean acidification provides an optimistic outlook for this species. However, research on this topic is still limited and if our findings on otolith formation are any indicator, then these fish are not entirely resistant to acidification," said Bignami, a Marine Biology and Fisheries PhD candidate at UM.

The study is the first to report impacts of ocean acidification on a large, pelagic tropical fish species. "We need additional studies on study how fish, especially those that are ecologically and economically important, react to these environmental changes if we want to find ways to potentially mitigate the effects," Bignami added.

Cobia larvae used in this study were produced from broodstock raised at the UM Experimental Hatchery.
