Are Dogs 'Kids?': Owner-dog relationships share striking similarities to parent-child relationships
June 21, 2013 ? People have an innate need to establish close relationships with other people. But this natural bonding behaviour is not confined to humans: many animals also seem to need relationships with others of their kind. For domesticated animals the situation is even more complex and pets may enter deep relationships not only with conspecifics but also with their owners. Scientists at the University of Veterinary Medicine, Vienna (Vetmeduni Vienna) have investigated the bond between dogs and their owners and have found striking similarities to the parent-child relationship in humans.
Their findings are published in the journal PLOS ONE.
Domestic dogs have been closely associated with humans for about 15,000 years. The animals are so well adapted to living with human beings that in many cases the owner replaces conspecifics and assumes the role of the dog's main social partner. The relationship between pet owners and dogs turns out to be highly similar to the deep connection between young children and their parents.
The importance of the owner to the dog
One aspect of the bond between humans and dogs is the so-called "secure base effect." This effect is also found in parent-child bonding: human infants use their caregivers as a secure base when it comes to interacting with the environment. Until recently the "secure base effect" had not been well examined in dogs. Lisa Horn from the Vetmeduni's Messerli Research Institute therefore decided to take a closer look at the behaviour of dogs and their owners. She examined the dogs' reactions under three different conditions: "absent owner," "silent owner" and "encouraging owner." The dogs could earn a food reward, by manipulating interactive dog toys. Surprisingly, they seemed much less keen on working for food, when their caregivers were not there than when they were. Whether an owner additionally encouraged the dog during the task or remained silent, had little influence on the animal's level of motivation.
When the owner is replaced by a stranger
In a follow-up experiment, Horn and her colleagues replaced the owner with an unfamiliar person. The scientists observed that dogs hardly interacted with the strangers and were not much more interested in trying to get the food reward than when this person was not there. The dogs were much more motivated only when their owner was present. The researchers concluded that the owner's presence is important for the animal to behave in a confident manner.
Why do adult dogs behave like human children?
The study provides the first evidence for the similarity between the "secure base effect" found in dog-owner and child-caregiver relationships. This striking parallel will be further investigated in direct comparative studies on dogs and children. As Horn says, "One of the things that really surprised us is, that adult dogs behave towards their caregivers like human children do. It will be really interesting to try to find out how this behaviour evolved in the dogs with direct comparisons."

Obama to unveil climate plan in Tuesday speech
WASHINGTON (AP) ? President Barack Obama says he'll unveil a national plan to combat climate change in a speech Tuesday.
Obama says in an online video the White House released Saturday that he'll lay out his vision for reducing carbon pollution, preparing the U.S. for the effects of climate change and leading other nations in the global effort.
Obama's speech Tuesday afternoon at Georgetown University will come the day before he leaves for a weeklong trip to three African nations.
"There's no single step that can reverse the effects of climate change," Obama says in the video. "But when it comes to the world we leave our children, we owe it to them to do what we can."
He says scientists must design new fuels and energy sources, and workers must prepare for a clean energy economy.
Obama isn't saying what specifics he'll lay out. But White House aides have suggested the steps will include renewable energy and energy-efficient appliances and buildings. The plan is also expected to involve the Environmental Protection Agency using its authority under the Clean Air Act to regulate heat-trapping pollution from coal-fired power plants.

G-rated films are a tough sell in superhero era
Movies 
20 hours ago
Two family-aimed films are hitting theaters in the next two weeks. "Monsters University" is an animated 3-D movie about zany, friendly monsters -- one with just one eyeball -- and how they interact with humans. (Spoiler: They scare them.) "Despicable Me 2" is also an animated 3-D movie about zany, friendly monsters -- some with just one eyeball -- and how they interact with humans. (Spoiler: They work for them.)
Disney, Universal
That's Mike from "Monsters University" on the left, and a minion from "Despicable Me 2" on the right. Can you tell which movie is rated G and which PG?
From that description, is it immediately clear which film is rated G, for General Audiences, and which one PG, meaning Parental Guidance suggested?
If it's not clear to you ("Monsters University" gets the G), you're not alone.
"I do think there is less of a clear line between G and PG than there is between PG-13 and R," said Vincent Bruzzese, chief executive officer of the Worldwide Motion Picture Group, a consultancy serving the entertainment industry. "It's very clear what makes something an R. If you say the F-word X number of times, it's an R. But why are 'Cars 2' and 'Rio' G, and yet 'Madagascar' or 'The Lorax' PG? What is the difference there? I'm not sure."
The Motion Picture Association of America, which determines movie ratings, did not respond to a request for comment for this story.
Bruzzese's company's research shows that not only do many parents not understand what makes a movie a G, to some of them, that family-friendly rating might even be a deterrent, especially if they have older children.
"We actually see that parents have no problem taking (5- or 6-year-olds) to a PG movie," Bruzzese said. "But they'll have trouble getting their 10- or 12-year-old to go to a G movie."
And if parents do want to seek out a G movie, good luck. Many movies that sound like they should be rated G tend to get the older rating. May's animated "Epic," about a girl who's shrunk to the size of a bug and helps a race known as the Leaf Men, was rated PG for "mild action, some scary images and brief rude language." July release "Turbo," about a garden snail who dreams of winning the Indy 500, is rated PG. (Does the snail swear?) August sequel "The Smurfs 2" isn't yet rated, but it'll almost certainly be PG like the 2011 original.
"The G rating has all but disappeared from theatrical releases other than one or two animated films each year," said Nell Minow, who advises parents about movies as The Movie Mom. "It's all about money. School-age kids think that G-rated movies are 'babyish,' so only Disney can get away with it."
With so much movie information available online, today's parents today don't need to rely only on the MPAA ratings. "(Parents) do their own investigation of films," Bruzzese said. "They're able to go online and look up -- whether it's user comments or more about the plot, more scenes -- they're able to find enough information to give them that (knowledge)."
Ben Boychuk of Rialto, Calif., is one of those parents. "I don't have a hard-and-fast rule about MPAA ratings," said Boychuk, who has an 11-year-old son and 5-year-old daughter. "I'll make a judgment based on whether I've seen the movie or barring that, by researching reviews and audience comments. IMDb is an invaluable resource -- what the Internet was meant for."
Wondering what has shifted since the days when kids saw only G-rated films? Experts point to many changes, including the addition of the PG-13 rating in 1984, the availability of movies of all ratings on home video and cable television, and the emergence of a generation of parents who grew up with such kid-tempting action films as 1977's "Star Wars." But a web-slinging, wall-crawling hero in tights might have something to do with it too.
"The family audience clearly has evolved in that it really, really started way back with the original 'Spider-Man' with Tobey Maguire," said Bruzzese. The 2002 PG-13-rated blockbuster "brought in a family audience to what would traditionally have been an older-skewing movie," he said.
Now, he said, "Today's 10-year-old is seeing what a 15-year-old would have seen 10 or 15 years ago."
Boychuk's family is a perfect example. Son Benjamin saw Maguire's "Spider-Man" on DVD at age 4 or 5. "He watched it at least a dozen times," Boychuk said. "The Green Goblin frightened him at first, but he wanted to see the movie again as soon as it was over."
But Boychuk notes that parents need to know their own children, who may be ready for different films at different ages. "My son was always great in movie theaters," he said. "My daughter (Isabella) is a different story. She can't handle most scary stuff, though she loves the classic Disney movies. ... I tend to be more vigilant with what we let her watch."
And the MPAA rating might not be the ultimate determining factor in how frightening a movie really is. In 2011, when TODAY.com asked readers to name the scariest scene in children's films, a scene from G-rated "Toy Story 3" repeatedly popped up. In it, Woody, Buzz Lightyear and the other toys are on what seems like an unstoppable moving ramp pushing them into a giant incinerator, with flames leaping high.
"As I think about it now, Bella was freaked out by the incinerator scene -- and so was I!" Boychuk said. "But Benjamin wasn't bothered too much."
The G rating will almost certainly continue to shift in meaning and usage, Bruzzese believes.
"If you look at the last 10 G-rated movies, half are either concerts or documentaries," he said. "More and more, as that becomes prevalent, the G rating will stand for not just the 'Winnie the Poohs' of the world, but will stand for things like (Disneynature 2012 documentary) 'Chimpanzee' or IMAX or a concert show. The G might start standing for non-traditional movie entertainment that's not offensive to any age group, whereas PG becomes the new G."

Clot-buster trial reveals long-term benefits for stroke patients
June 20, 2013 ? Patients given a clot-busting drug within six hours of a stroke are more likely to have a long-lasting recovery than those who do not receive the treatment, new research has found.
A study of more than 3000 patients reviewed the effects of the drug rt-PA, which is given intravenously to patients who have suffered an ischaemic stroke.
The international trial, led by the University of Edinburgh, found that 18 months after being treated with the drug, more stroke survivors were able to look after themselves.
Patients who received rt-PA had fewer long-term problems with self-care and mobility, and experienced less pain and discomfort than those who did not.
Treatment also reduced the number of patients who needed help from other people from 51 per cent to 43 per cent.
An ischaemic stroke happens when the brain's blood supply is interrupted by a blood clot. The damage caused can be permanent or fatal. Stroke symptoms include paralysis down one side and speech problems.
The study, published in The Lancet Neurology, builds on the world's largest ever trial of the drug, which was published last year. It found that treatment with rt-PA improved health for stroke survivors up to six months following an ischaemic stroke.
This latest results from the trial show the quality of life of stroke patients 18 months after receiving rt-PA. It involved stroke patients in 12 countries between 2000 and 2011 -- half of whom were treated with intravenous rt-PA and half of whom were not.
Researchers found that for every 1000 patients given rt-PA within six hours of stroke, by 18 months, 36 more will not need help from others than if they had not been given the drug.
The benefits of using rt-PA do come at a price, say researchers. Patients are at risk of death within seven days of treatment because the drug can cause a secondary bleed in the brain.
Stroke experts stress that these mortality figures need to be taken in context of deaths from stroke. Without treatment, one third of people who suffer a stroke die, with another third left permanently dependent and disabled.
Researchers say that because of the threat of death and disability, many stroke patients are prepared to take the early risks of being treated with rt-PA to avoid being disabled.
About half of those who took part in the trial were aged over 80.
Chief investigator Professor Peter Sandercock of the University of Edinburgh's Centre for Clinical Brain Sciences said: "The trial team is delighted that, even for the elderly, rt-PA significantly improves life after stroke in the longer-term. Our results underline the benefits of treating patients with the drug as soon as possible and justify extending treatment to those aged 80 and over. We hope that these new data will encourage wider use."

Light and nanoprobes detect early signs of infection
June 20, 2013 ? Duke University biomedical engineers and genome researchers have developed a proof-of-principle approach using light to detect infections before patients show symptoms.
The approach was demonstrated in human samples, and researchers are now developing the technique for placement on a chip, which could provide fast, simple and reliable information about a patient. A diagnostic device based on this chip also could be made portable.
The researchers developed a silver-based nanoparticle that homes in on a specific molecular marker that spills into the bloodstream at the first stages of an infection. When light is aimed at the sample, the nanoparticle attached to a molecular marker will reflect a distinct optical fingerprint.
"We have demonstrated for the first time that the use of these nanoprobes can detect specific genetic materials taken from human samples," said Tuan Vo-Dinh, the R. Eugene and Susie E. Goodson Distinguished Professor of Biomedical Engineering at Duke' Pratt School of Engineering and director of The Fitzpatrick Institute for Photonics at Duke. He is also a professor of chemistry.
The results of the Duke experiments appear online in the journal Analytica Chimica Acta. Hsin-Neng Wang, a post-doctoral fellow in Vo-Dinh's laboratory, was the first author of the paper.
In this interdisciplinary project, the Vo-Dinh team collaborated closely with scientists at Duke's Institute for Genome Sciences & Policy (IGSP) who have developed a method of measuring the host's response to infection through RNA profiling.
The research is supported by the National Institutes of Health, the Defense Advanced Projects Agency, the Department of Defense and the Wallace H. Coulter Foundation.
In the Duke experiments, the nanoprobes are used in conjunction with a phenomenon first described in the 1970s known as surface-enhanced Raman scattering (SERS). When light, usually from a laser, is shined on a sample, the target molecule vibrates and scatters back in its own unique light, often referred to as the Raman scatter. However, this Raman response is extremely weak.
"When the target molecule is coupled with a metal nanoparticle or nanostructure, the Raman response is greatly enhanced by the SERS effect -- often by more than a million times," said Vo-Dinh, who has been studying the potential applications of SERS for decades.
"This important proof-of-concept study now paves the way for the development of devices that measure multiple genome-derived markers that will assist with more accurate and rapid diagnosis of infectious disease at the point of care," said Geoffrey Ginsburg, director of genomic medicine at the IGSP, executive director of the Center for Personalized Medicine at Duke Medicine, and a professor of medicine and pathology.
"This would guide care decisions that will lead to more effective treatment and improved outcomes of antimicrobial therapy," Ginsburg said. "Point-of-care diagnostics holds great promise to accelerate precision medicine and, more importantly, help patients in limited-resource settings gain access to molecular testing."

Alcon Planning 'Dolphin Tale' sequel with original cast
By Greg Gilman
LOS ANGELES (TheWrap.com) - Alcon Entertainment is developing a sequel to the 2011 family film, "Dolphin Tale," co-founders and co-CEOs Andrew Kosove and Broderick Johnson announced on Tuesday.
The entire original cast, including Harry Connick Jr., Ashley Judd, Morgan Freeman and Kris Kristofferson, is in negotiations to reunite with director Charles Martin Smith for the sequel. It has not yet officially greenlit, but Warner Bros. has set aside a September 19 release date in 2014.
"Dolphin Tale 2" which will tell another true story inspired by the life of Winter - the dolphin who is rescued from a crab trap by a young boy in the first film.
This time, however, a new baby dolphin named Hope, who was rescued by the Clearwater Marine Aquarium in 2010, will join Winter. Both animals will play themselves.
Alcon is producing and financing the film.

Dell XPS 10 with Windows RT gets major price cut: base model now $300
We don't know for sure that Dell's been experiencing the weak demand for Windows RT Samsung's been so vocal about, but significant price cuts to its XPS 10 tablet hybrid suggest it hasn't exactly been flying off the shelves. Not only has the $500 tag for the tablet with 32GB of storage dropped to $300, but adding another 32GB now only costs $50 more, instead of $100. Savings have extended to the keyboard dock, too -- opting for the bundle used to increase the overall cost by $180, but now that peripheral is only a $50 extra. (Make sure to lead with the bundle though, as it's $100 if added from the tablet-only customization options). The cost of optional LTE hasn't changed, however, so that 4G radio still costs an additional $100. While we haven't reached fire sale territory just yet, the cuts are still a welcome discount for consumers. In the interest of preserving profit margins, perhaps Dell should ask Acer's president to consult next time it's cooking up new hardware.
