GM recalls 221,558 sedans for fire risk

Written By Unknown on Senin, 22 September 2014 | 00.52

DETROIT — General Motors is recalling 221,558 Cadillac XTS and Chevrolet Impala sedans because the brake pads can stay partially engaged even when they're not needed, increasing the risk of a fire.

The recall involves Cadillacs from the 2013-2015 model years and Impalas from the 2014 and 2015 model years. There are 205,309 vehicles affected in the U.S.; the rest of the vehicles are in Canada and elsewhere.

GM says the electronic parking brake arm that applies pressure to the back of the brake pads may not fully retract after use. If the brake pads stay partially engaged with the rotor, excessive brake heat may result in a fire.

GM says it knows of no accidents or injuries related to the defect.

GM will notify owners and repair the vehicles for free.

Pet care comes to Walgreens

A Florida veterinary company is partnering with Walgreens to offer lower-cost, walk-up clinics for dogs and cats in the parking lots of about 50 of the drugstore chain's Massachusetts stores.

Starting this weekend, ShotVet is offering preventative care services — including rabies and other vaccines, heartworm and Lyme disease tests, and micro-chipping — by state-licensed veterinarians.

"The price is probably about a 70 percent savings (from traditional vet offices)," said Jen Borgman, CEO of ShotVet, which has been offering its services in conjunction with Walgreens in Florida and Georgia for several years. "It's challenging for people to afford veterinary care, and many, many pets are going without. That's not good for the communities, and that's not good for the animals."

ShotVet will visit each participating Walgreens for an hour each month with a vet, technician and "client educator" who explains its packages. No appointments are required.

"There's usually a long line … so we advise people to get there early," Borgman said. "It's no exam fees. What customers say over and over again is this was fast, convenient, easy. And the experience is much less stressful for the pet as well as the owner."

The service is aligned with Walgreens' mission "to help people get, stay and live well," said Phil Caruso, spokesman for the Deerfield, Ill.-based company. "Pets are valued members of many families, and an opportunity to provide a service like this in our parking lots just helps us reiterate our mission," he said.

But the Massachusetts Veterinary Medical Association finds ShotVet's services "very problematic," according to executive director Susan Curtis. "We want what's in the best interest of the animals and public health, and we want to see all animals properly vaccinated, but this issue is very concerning," she said.

State law requires a "veterinary-client patient relationship" be established before any vaccination is given, Curtis notes. That requires sufficient knowledge of an animal by a vet to "initiate at least a general or preliminary diagnosis" of its medical condition. This means the vet has recently seen and is personally acquainted with the keeping and care of the animals by virtue of an examination and/or by medically appropriate and timely visits to where the animal is kept, the law states.

"In this type of environment, there isn't that relationship," Curtis said. "There should be a physical exam, there should be an assessment, there should be a knowledge of the animal and the animal's living situation, and there should be a relationship."

But ShotVet founder Dr. Wesley Borgman counters that ShotVet vets examine every animal before preventative action is taken.

"Many animals are going unvaccinated," he said. "We go out and service clients that many times aren't going to see a veterinarian. We don't replace the (animal hospital) services. In fact, we refer cases to our colleagues at the animal hospitals … to take care of things we can't handle."

SpaceX launches 3-D printer, other station gear

CAPE CANAVERAL — A SpaceX cargo ship rocketed toward the International Space Station on Sunday, carrying the first 3-D printer for astronauts in orbit.

In all, the unmanned Dragon capsule is delivering more than 5,000 pounds of space station supplies for NASA.

Dragon should reach the space station Tuesday. It's the fifth station shipment for the California-based SpaceX, one of two new commercial winners in the race to start launching Americans again from home soil.

The space station was soaring over the South Pacific when the SpaceX Falcon 9 thundered into Florida's pre-dawn sky. Sunday's weather was ideal for flying, unlike Saturday, when rain forced a delay. The rocket was visible for nearly three minutes as it sped out over the Atlantic, with the Orion constellation as a backdrop.

"What a beautiful morning it was," said Sam Scimemi, NASA's space station division director.

Sunday was a red-letter day for NASA in more ways than one.

Besides the flawless launch, the space agency's Maven spacecraft was on the verge of reaching Mars. The robotic explorer was scheduled to go into orbit around Mars late Sunday night.

The space station-bound 3-D printer was developed by Made in Space, another California company. It's sturdier than Earthly models to withstand the stresses of launch, and meets NASA's strict safety standards. The space agency envisions astronauts one day cranking out spare parts as needed. For now, it's a technology demonstrator, with a bigger and better model to follow next year.

A $30 million device for measuring ocean winds is also flying up on Dragon, along with 20 mice and 30 fruit flies for biological research and metal samples for a golf club manufacturer looking to improve its products.

Much-needed spacesuit batteries are on board as well, along with the usual stash of food, clothes and electronic gear. Routine U.S. spacewalks were put on hold following last year's close call with an astronaut's flooded helmet. That problem was solved, then the battery fuses were called into question. NASA hopes to resume spacewalks next month.

NASA is paying SpaceX and Virginia-based Orbital Sciences Corp. to make regular station deliveries. The SpaceX service began two years ago.

Just this past week, SpaceX — led by billionaire Elon Musk — won an even bigger and more prestigious contract to transport U.S. astronauts to the orbiting outpost, along with Boeing. Dragon rides could begin as early as 2016 or 2017.

NASA's ability to launch its own crews ended with the shuttle program in 2011. Russia has been providing rides on its Soyuz spacecraft for a hefty price.

Another American astronaut is scheduled to blast off from Kazakhstan aboard a Russian Soyuz later this week, along with two Russians, one of them a woman, a rarity for Russia. They will join the one American, one Russian and one German already in orbit.

SpaceX was delighted with Sunday's success and the road ahead, and could hardly wait for the party to begin.

"Nothing like a good launch," observed Hans Koenigsmann, vice president of mission assurance for SpaceX. "It's just fantastic."

EdTrip’s a field day for teachers

For most students, field trips are something to look forward to as a day away from the classroom and, every so often, as a chance to see for themselves something truly transformative, something they've only heard about in school or read about in books.

But for teachers, coordinating these trips can be a logistical nightmare of finding the right destination, drawing up an itinerary and collecting dozens of parental-consent forms — all things that take time away from teaching.

So a MassChallenge finalist offers to do all of that for them, all the while drumming up business for Bay State venues.

"Coordinating field trips is a massive investment of time if you're a teacher," said EdTrips CEO Jakob Garrow, who used to work for an educational travel company with his co-founder, Laura Wallendal. "We realized if there were a way to make it easier for teachers, more of them would take trips."

The two teamed up with Jillian Kando, their chief technology officer, to create a website that, in addition to collecting payments and parents' permission, allows teachers to search for a destination by name, subject or the grade they teach. Or they can use EdTrips' concierge service, which passes along a 20 percent discount off the cost of tickets to their destinations if they choose from a curated list of field-trip matches based on criteria such as their grade, their budget and the distance they want to travel.

Teachers pay nothing to use the website, while venues pay EdTrips a percentage of overall ticket sales for each trip organized through the site.

Since April, the company has partnered with 247 Massachusetts destinations, including Boston PhotoWalks Tours and Scavenger Hunts, Peabody Essex Museum and Woods Hole Science Aquarium, with plans to expand to venues in other states.

Peter McGovern, who teaches Spanish and Mandarin Chinese at Catholic Memorial School in West Roxbury, hopes to use the website to organize trips that would incorporate cultural opportunities such as a show or a tour of Chinatown, where his students could practice their Mandarin.

"Students could see the real-world value of being able to communicate with people in their language," he said. "And having the permission slip collection and payment online would save a lot of time."

Since Labor Day, at least four teachers have used EdTrips to pay by credit card for field trips to the Paul Revere House, which otherwise takes only cash or checks the day of the trip, said Emily Holmes, education director of the Paul Revere Memorial Association, which runs the historic North End site.

"Definitely we're hoping we'll have exposure to a new audience," Holmes said.

NASA's Maven explorer arriving at Mars after year

CAPE CANAVERAL, Fla. — It's showtime at Mars.

NASA's Maven spacecraft is on track to reach the red planet late Sunday night following a journey spanning 10 months and 442 million miles.

If all goes well, the robotic explorer will slip into Martian orbit for a year or more of atmospheric study. It's designed to circle the planet, not land.

Maven will be the first spacecraft to focus on the upper atmosphere of Mars. Scientists believe the Martian atmosphere holds clues as to how Earth's neighbor went from being warm and wet billions of years ago to cold and dry. That early wet world may have harbored microbial life, a tantalizing question yet to be answered.

The $671 million mission began with a launch from Cape Canaveral last November.

Arab states lag in media war against extremists

DUBAI, United Arab Emirates — As the Islamic State group battles across Syria and Iraq, pushing back larger armies and ruling over entire cities, it is also waging an increasingly sophisticated media campaign that has rallied disenfranchised youth and outpaced the sluggish efforts of Arab governments to stem its appeal.

Long gone are the days when militant leaders like Osama bin Laden smuggled grainy videos to Al-Jazeera. Nowadays Islamic State backers use Twitter, Facebook and other online platforms to entice recruits with professionally made videos showing fighters waging holy war and building an Islamic utopia.

The extremist group's opponents say it is dragging the region back into the Middle Ages with its grisly beheadings and massacres, but its tech-savvy media strategy has exposed the ways in which Arab governments and mainstream religious authorities seem to be living in the past.

Most Arab governments see social media as a threat to their stability and have largely failed to harness its power, experts say. Instead, they have tried to monitor and censor the Internet while churning out stale public statements and state-approved sermons on stuffy government-run media.

Last week, Saudi Arabia's top council of religious scholars issued a lengthy Arabic statement via the state-run news agency denouncing terrorism and calling on citizens to back efforts to fight extremist groups like the Islamic State and al-Qaida. Leading Sunni Muslim authorities in Egypt have issued similar government-backed statements.

Compare that to the Islamic State group. Its Furqan media arm produces slick videos complete with interviews, graphics and jihadist hymns echoing in the background, with Arabic and English subtitles. It promotes the videos and its glossy monthly magazines on an array of social media, reaching out to people in the Arab world and beyond. Islamic State fighters even tweet live from the battlefield, giving real-time updates and waging theological debates with online detractors.

"They definitely have an electronic army behind them," said Ray Kafity, vice president of FireEye for the Middle East, Turkey and Africa. The company manufactures IT solutions for defending against cyber threats.

The Islamic State boasts thousands of foreign fighters, some of whom were first drawn to it in the privacy and security of cyberspace. It also uses social media for fundraising.

Fadi Salem, a Dubai-based researcher on Internet governance in the Arab World, said the immediate response of Middle Eastern governments to the power of social media has been to "control, block and censor as much as possible."

"Very few governments viewed this as an opportunity rather than a risk," Salem said.

Egypt shut down access to the Internet during the bloodiest day of the 2011 uprising that toppled President Hosni Mubarak, and Syria cut off access in rebellious provinces shortly after the start of the revolt against Bashar Assad later that spring.

Iraq's government followed suit in June of this year, when the Islamic State group swept across much of the country's north and west. The government cut off Internet access to several areas overrun by militants, including Mosul, Iraq's second largest city.

A study by The Citizen Lab at the University of Toronto showed that despite blocking mobile messaging apps and social media platforms, Iraq's authorities failed to block seven websites affiliated with or supportive of the Islamic State group. New accounts appear almost as quickly as old accounts are reported and taken down.

"It's hard to wage a war with ideas online," said Abdulaziz Al-Mulhem, the spokesman for the Saudi Ministry of Information and Culture. "When we talk about monitoring or controlling social media it is like trying to control air, and this of course is hard."

Facebook says it has 71 million active monthly users in the Middle East, and youth between the ages of 15 and 29 make up around 70 percent of Facebook users in the Arab region, according to a report by the Dubai School of Government.

Facebook's Elizabeth Linder says Middle Eastern governments are still in the early stages of realizing the full potential of social media. She advises governments on how they can better use Facebook for diplomacy.

"The most important thing is to be there," she told The Associated Press on the sidelines of a social media conference in Dubai. "And that's something that I really do encourage governments to do, not to leave the space but to enter the space."

The United States, which has long struggled to craft an effective public diplomacy in the region, has taken note. The U.S. State Department launched a "Think Again Turn Away" campaign on YouTube, Facebook and Twitter, with Arabic and English videos similar in style to those of al-Qaida and the Islamic State group. One video is titled "Airing al-Qaida's dirty laundry" and another shows images of children allegedly killed by these groups.

But none have gained the traction of the Islamic State's videos, which pair brutal images of mass shootings and beheadings — aimed at striking fear in the hearts of its enemies — with heroic portrayals of its fighters as models of bravery and piety.

A slick 55-minute video entitled "Flames of War" came with its own trailer, and features images of exploding tanks and wounded U.S. soldiers. The video, which came out this month, was allegedly released by the Islamic State group's Al-Hayat media center. It idealizes militants as "warriors" and "truthful men."

The message to alienated young men in the region and abroad is that they too can wage holy war, exact revenge on those seen as oppressing Muslims and help build a just society based on divine law.

The videos that have gained the most attention in the West are those that show a masked man beheading two American journalists and a British aid worker in the desert. But others document life in militant-held Raqqa in eastern Syria, and cheerfully invite potential recruits to move there.

"We want to be your brothers and for you to be our brothers," an Islamic State fighter tells Syrian men and children in a video entitled "The best ummah" — or Muslim society.

The Arabic video with English subtitles depicts a community where pious men police the streets, eliminating drugs and alcohol and making sure everyone prays together at the mosque. The militants distribute food to those in need and ensure fair prices in the local markets.

For many it's a compelling vision of a better world, one that stands in stark contrast with most states in the region, in which aging autocrats preside over governments seen as irredeemably corrupt and stagnant. Combatting that vision will require more than simply silencing its advocates, experts say.

"Pure censorship and blocking is not really working. It will continue to be a cat-and-mouse game," Salem said. "Another way is to use these tools to attract people away from these ideas. A combination of both is required."

Astronauts getting 3-D printer at space station

CAPE CANAVERAL, Fla. — The 3-D printing boom is about to invade space.

NASA is sending a 3-D printer to the International Space Station in hopes that astronauts will be able to one day fix their spacecraft by cranking out spare parts on the spot.

The printer, made by a Northern California company called Made in Space, is among more than 5,000 pounds of space station cargo that's stuffed into a SpaceX Dragon capsule that was supposed to lift off before dawn Saturday. Rainy weather forced SpaceX to delay the launch until Sunday.

Besides real-time replacement parts at the station, NASA envisions astronauts, in the decades ahead, making entire habitats at faraway destinations like Mars.

"If we're really going to set up shop on Mars," we have to do this, Jeff Sheehy, NASA's senior technologist, said Friday. "We really can't afford to bring everything we need for an indefinite amount of time. We'll need to get to the point where we can make things that we need as we go."

At Kennedy Space Center, the company showed off a number of objects made by its 3-D printers. On display was a scaled-down model of an air filter that the Apollo 13 astronauts devised to survive their aborted moon mission in 1970. It took five hours to print the model in a lab.

SpaceX is making the supply run for NASA, the same California company that just won a huge contract to deliver U.S. astronauts to the space station. Its Falcon 9 rocket with an unmanned Dragon is scheduled to blast off at 1:52 a.m. Sunday; slightly better weather is expected.

Other Dragon payloads high on the cool or curious factor: a mouse X-ray machine and 20 mice; 30 fruit flies expected to have a population explosion in orbit, metal plating samples for a private research effort to build stronger golf clubs, and a $30 million instrument to measure the surface wind over Earth's oceans and improve hurricane forecasting.

The small 3-D printer on board is a demo unit meant to churn out sample items made from the same type of plastic used for Lego bricks.

It was designed to operate safely in weightlessness inside a sealed chamber. The printing process is the same as on Earth, creating an object with layer upon layer of plastic.

Once returned to Earth, the little 3-D creations will be "pulled and twisted and peeled and subjected to a lot of tests to determine the quality of the parts," said Sheehy.

Combined with efforts on the ground to make 3-D rocket parts out of metal — even entire engines — the space demonstrations "will give us confidence that the stuff we make by this method, even though it's new and innovative" does, indeed, have the durability of traditional parts, he said.

The space 3-D printer is barely a foot tall, 9½ inches wide and 14½ inches deep, counting the knobs on the front. A commercial 3-D printer — twice the size and dubbed "big brother" — will fly up next year, followed by a grinding machine for recycling discarded 3-D pieces.

"This is a huge, huge time for us," said Brad Kohlenberg, business development engineer for Made in Space.

The Mountain View, California, company has a staff of fewer than 25; most of them traveled to Cape Canaveral for the launch attempt.

This will be the fifth space station shipment for SpaceX, counting the 2012 test flight. The space agency also is paying Orbital Sciences Corp. of Virginia to make periodic deliveries.

SpaceX, along with Boeing, won huge contracts Tuesday for delivering U.S. astronauts to the space station beginning in 2017. That will enable NASA to stop relying so heavily on Russia, currently the only space station partner able to send crews up and down.

The Hawthorne, California, company founded by billionaire Elon Musk is shooting for its first crewed launch in 2016. The flight test crew will be a mix of NASA and SpaceX employees, confirmed Hans Koenigsmann, vice president of mission assurance for SpaceX. He said the company is still working out the details on whom to send up.

Oculus unveils new prototype VR headset

LOS ANGELES — Oculus has unveiled a new prototype of its virtual reality headset. However, the VR company still isn't ready to release a consumer edition.

The hew headset intended for creators of VR experiences is nicknamed Crescent Bay and features a higher resolution and refresh rate, integrated headphones and 360-degree head tracking.

"That was not easy," Oculus CEO Brendan Iribe told the audience Saturday at the company's first-ever developers conference. "It's still not perfect. None of this is perfect yet, but it's much, much better."

Oculus' headset covers a user's eyes and can create immersive worlds that react to head movement.

The original prototype of the Oculus Rift headset was unveiled in 2012 and has received considerable attention from film and video game makers. Oculus released a second prototype headset to developers earlier this year. Iribe said 100,000 development kits have been shipped to 130 countries.

"I never expected it go this quickly," Iribe said. "None of us did."

The Irvine, California-based Oculus VR Inc. was acquired by Facebook earlier this year for $2 billion. Iribe said Oculus' staff has doubled in the six months since the acquisition.

"We're really spiriting toward the consumer version," he said.

Oculus recently teamed up with Samsung to introduce Gear VR, a $200 headset with a slot for using the Galaxy Note 4 smartphone as a VR display.

Over the past two years, Oculus' technology has been demonstrated at events like San Diego Comic-Con and the Electronic Entertainment Expo with interactive experiences that recreate scenes from the "X-Men" and "Pacific Rim" films and thrust users into an intergalactic dogfight in the game "EVE: Valkyrie."

Iribe reiterated several times during his talk at the Oculus Connect conference that creating a sense of presence would be integral for the widespread adoption of VR technology, which continues to leave some users feeling queasy despite Oculus' strides in creating lower latency and more realistic imagery inside the goggles.

"You should believe you're there and feel great, even if you're super-sensitive like me," Iribe said.

Hyundai Santa Fe’s onetime brake lockup is puzzling

Last week I parallel-parked my 2003 Hyundai Sante Fe. I came out to drive away and went about 3 feet before the car stopped like the brakes had locked up. I went back and forth about 3 feet at least three more times with the same results. I left the car and came back the next morning and drove to a garage with no problems. The garage scanned all vehicle control modules for codes — none found. They also found no service bulletins from Hyundai pertaining to this symptom. They inspected all brake components — all are in good condition. Any suggestion?

I'm not often completely stumped by an automotive question, but this one has me really intrigued. Looking at the issue logically, my first thought is something physically stopping the vehicle from moving more than 3 feet.

Do you have any friends — or enemies — who might play a trick on you like a strategically placed pair of cinder blocks? I remember an unnamed friend who, for the fun of it, chained the rear axle of an old Chevy wagon to the adjacent fire hydrant and watched as his friend tried to pull away. I'll leave the results to your imagination!

What kind of mechanical or electronic issue could have caused this and then suddenly disappeared without a trace? I'm open to suggestions, but the only normal "action" that might have somehow compounded into this is initialization of the antilock braking system (ABS). Each time the vehicle is started, in the first few miles per hour of driving, the ABS tests itself by actuating the pump, dump valves and solenoids to make sure they're working. This may be felt as a slight vibration in the brake pedal.

With that said, this initialization only occurs once per key cycle, so it doesn't seem particularly likely to be the culprit. In fact, no brake lockup would seem likely because the vehicle rolls roughly one tire revolution before the lockup.

Anyone else want to take a shot at this?

Oh, almost forgot — was there a parking ticket on the windshield? And did you check for a wheel lock to disable the car?

I have a 2014 Acura RDX that is a very nice vehicle except for the fact that the passenger seat cannot be raised vertically. My wife is fairly short and sits too low compared with the driver's side, which has an electric lift. The dealer said that there is no fix for this. It seems like a simple problem. Have you heard of any electric, or manual lifts for this ? Or, simply some wedges installed under the seat mounts?

You could try a mobility store to find a booster for her seat, or perhaps an auto upholstery shop could build up the seat with thicker or firmer foam.

The reason it seems simple yet there's no solution from the dealer is that any change that alters a motor vehicle creates a liability issue for the dealer and carmaker.

Personally, I have installed spacers under the seat mounts on a couple of my personal vehicles, but like I said, I'd suggest a visit to a mobility store.

When I was topping off the oil in my car I accidentally put in half a quart of DEX/MERC automatic transmission fluid. Can I drive it? If yes, how far before changing the oil? Or do I need to change it now?

Automatic transmission fluid is primarily a high-quality lubricating oil with special additives for the transmission, so you probably don't have an immediate problem. But the fact that you were topping up the oil means it's been in the crankcase for a while, so why not get the oil changed now and put the worry aside?

Paul Brand, author of "How to Repair Your Car," is an automotive troubleshooter, driving instructor and former race -car driver. Readers may write to him at: Star Tribune, 425 Portland Ave. S., Minneapolis, Minn., 55488 or via email at paul brand@startribune.com. Please explain the problem in detail and include a daytime phone number.

China, US, India push world carbon emissions up

WASHINGTON — Spurred chiefly by China, the United States and India, the world spewed far more carbon pollution into the air last year than ever before, scientists announced Sunday as world leaders gather to discuss how to reduce heat-trapping gases.

The world pumped an estimated 39.8 billion tons (36.1 billion metric tons) of carbon dioxide into the air last year by burning coal, oil and gas. That is 778 million tons (706 metric tons) or 2.3 percent more than the previous year.

"It's in the wrong direction," said Glen Peters, a Norwegian scientist who was part of the Global Carbon Project international team that tracks and calculates global emissions every year.

Their results were published Sunday in three articles in the peer-reviewed journals Nature Geoscience and Nature Climate Change.

The team projects that emissions of carbon dioxide, the main heat-trapping gas from human activity, are increasing by 2.5 percent this year.

The scientists forecast that emissions will continue to increase, adding that the world in about 30 years will warm by about 2 degrees Fahrenheit (1.1 degrees Celsius) from now. In 2009, world leaders called that level dangerous and pledged not to reach it.

"Time is running short," said Pierre Friedlingstein of the University of Exeter in England, one of the studies' lead authors. "The more we do nothing, the more likely we are to be hitting this wall in 2040-something."

Chris Field, a Carnegie Institution ecologist who heads a U.N. panel on global warming, called the studies "a stark and sobering picture of the steps we need to take to address the challenge of climate change."

More than 100 world leaders will meet Tuesday at the U.N. Climate Summit to discuss how to reverse the emissions trend.

The world's three biggest carbon polluting nations — China, the U.S. and India — all saw their emissions jump. No other country came close in additional emissions.

Indian emissions grew by 5.1 percent, Chinese emissions by 4.2 percent and the U.S. emissions by 2.9 percent, when the extra leap day in 2012 is accounted for.

China, the No. 1 carbon polluter, also had more than half the world's increases over 2012. China's increases are slowing because the Chinese economy isn't growing as fast as it had been, Peters said.

The U.S. had reduced its carbon emissions in four of the five previous years. Peters said it rose last year because of a recovering economy and more coal power.

Only two dozen of the about 200 countries cut their carbon emissions last year, led by mostly European countries. Spain had the biggest decrease.

The world emissions averaged to 6.3 million pounds (2.9 million kilograms) of carbon dioxide put in the air every second.
