Ice storm on horizon for Sunday













Ice storm


As icicles hang from Cloud Gate, Jay Ing of Chicago walks through Millennium Park in Chicago last February.
(Scott Strazzante, Chicago Tribune / January 26, 2013)



























































The National Weather Service has issued a winter storm watch for northeast Illinois that warns of an ice storm that is expected to arrive Sunday morning and last into Sunday night.


According to the agency, the region will be hit with freezing rain, possibly mixed with slee,t that will turn to rain as the temperatures rise above freezing over the course of the day. The agency warns of "significant" ice accumulation, up to a quarter-inch, making travel hazardous and possibly leading to downed tree limbs and power lines.


Because the ground is below freezing, the precipitation will freeze on contact, the agency said, leaving sidewalks as well as streets with that potentially dangerous coating of ice.





The agency also said that the storm "is still in the developing stages" and that any changes in temperature could make a big difference in the nature of the precipitation and how much there is.

4 tips for creating a successful Twitter parody account






The guy behind @GowanusDolphin learned his lesson the hard way


A chorus of Twitter elite got really angry on Friday when an opportunistic user decided to register @GowanusDolphin, a horrible account that premised itself on a dolphin trapped in New York‘s murky Gowanus Canal. 







Not sure how I feel about parody account @gowanusdolphin. Poor guy. Don’t find funny at all.

I don’t think I’m exaggerating when I say that this @gowanusdolphin account is far worse than the Holocaust.



— Joel Johnson (@joeljohnson) January 25, 2013



It’s because we all laughed at the fake Rahm Emanuel guy that these fucking things exist. We brought @gowanusdolphin on ourselves.

The offender, who has since apologized for being a jerk, learned his lesson the hard way. Don’t let the same fate befall you. Here, four helpful tips for creating a successful* Twitter parody account should the opportunity ever arise again:


1. Don’t use animals
Remember @BronxZooCobra fondly? Neither do we. Predicating your shiny new Twitter handle on a headline-grabbing animal is difficult for two reasons: (a) Animals don’t talk. You’re creating its voice from scratch; and (b) People tend to like animals more than they like other people, so as a rule of thumb, you should probably be making fun of actual human beings.

2. Don’t base it on news
When a mild 5.9-magnitude earthquake rattled New York in 2010, Twitter exploded with parody accounts. (“Boom!” and “Whoa!” and that sort of nonsense.) None of them were funny. None of them were sustainable. Take a lesson from Bloomberg social media director (and the web’s leading voice in parody account hatred) Jared Keller:



If you create a parody account within fifteen minutes of a news event you are the worst person on the planet and I hate you.

— Jared Keller (@jaredbkeller) January 25, 2013


3. Be funny
Ha ha, you have to actually be funny, which is easier said than done. And “humor,” as we all know, is 100 percent subjective and varies from person to person, NOT TO MENTION it requires constant mental dexterity that 99.99 percent of the population simply isn’t cut out for. So make it easy for yourself. Self-impose some parameters and employ a weird spin like @NYTOnIt or @__MICHAELJ0RDAN. Maybe you’ll even get a book deal! (Probably not.)


4. You probably shouldn’t make a parody account
Ignore everything I just said. Don’t make one. Sorry.

Fox orders futuristic cop drama pilot from J.J. Abrams, J.H. Wyman






LOS ANGELES (TheWrap.com) – Fox has given the green light to a police drama pilot from “Fringeexecutive producers J.H. Wyman and J.J. Abrams, the network said Friday.


Described as an “action-packed buddy cop show,” the untitled project takes place “in the near future, when all LAPD officers are partnered with highly evolved human-like androids.”






Wyman is writing and executive-producing the one-hour drama project, along with Abrams.


Abrams’s Bad Robot Productions is producing in association with Warner Bros. Television. Bad Robot’s Bryan Burk is also executive-producing, with the company’s Kathy Lingg serving as co-executive producer.


Abrams, who’s been tapped to direct the maiden installment of the revived “Star Wars” movie franchise, sold a comedy pilot, “Adulting,” to Fox late last year. That project, a single-camera, half-hour comedy, is based on the Kelly Williams Brown book “Adulting: How to Become a Grown-up in 387 Easy(ish) Steps.”


“Fringe,” which was also on Fox, wrapped up its series run with a two-hour finale earlier this month.

Diner’s Journal Blog: PepsiCo Will Halt Use of Additive in Gatorade

PepsiCo announced on Friday that it would no longer use an ingredient in Gatorade after consumers complained.

The ingredient, brominated vegetable oil, which was used in citrus versions of the sports drink to prevent the flavorings from separating, was the object of a petition started on Change.org by Sarah Kavanagh, a 15-year-old from Hattiesburg, Miss., who became concerned about the ingredient after reading about it online. Studies have suggested there are possible side effects, including neurological disorders and altered thyroid hormones.

The petition attracted more than 200,000 signatures, and this week, Ms. Kavanagh was in New York City to tape a segment for “The Dr. Oz Show.” She visited The New York Times on Wednesday and while there said, “I just don’t understand why they can’t use something else instead of B.V.O.”

“I was in algebra class and one of my friends kicked me and said, ‘Have you seen this on Twitter?’ ” Ms. Kavanagh said in a phone interview on Friday evening. “I asked the teacher if I could slip out to the bathroom, and I called my mom and said, ‘Mom, we won.’ ”

Molly Carter, a spokeswoman for Gatorade, said the company had been testing alternatives to the chemical for roughly a year “due to customer feedback.” She said Gatorade initially was not going to make an announcement, “since we don’t find a health and safety risk with B.V.O.”

Because of the petition, though, Ms. Carter said the company had changed its mind, and an unidentified executive there gave Beverage Digest, a trade publication, the news for its Jan. 25 issue.

Previously, a spokesman for PepsiCo had said in an e-mail, “We appreciate Sarah as a fan of Gatorade, and her concern has been heard.”

Brominated vegetable oil will be replaced by sucrose acetate isobutyrate, an emulsifier that is “generally recognized as safe” as a food additive by the Food and Drug Administration. The new ingredient will be added to orange, citrus cooler and lemonade Gatorade, as well Gatorade X-Factor orange, Gatorade Xtremo citrus cooler and a powdered form of the drink called “glacier freeze.”

Ms. Carter said consumers would start seeing the new ingredient over the next few months as existing supplies of Gatorade sell out and are replaced.

Health advocates applauded the company’s move. “Kudos to PepsiCo for doing the responsible thing on its own and not waiting for the F.D.A. to force it to,” said Michael Jacobson, executive director of the Center for Science in the Public Interest.

Mr. Jacobson has championed the removal of brominated vegetable oil from foods and beverages for the last several decades, but the F.D.A. has left it in a sort of limbo, citing budgetary constraints that it says keep it from going through the process needed to formally ban the chemical or declare it safe once and for all.

Brominated vegetable oil is banned as a food ingredient in Japan and the European Union. About 10 percent of drinks sold in the United States contain it, including Mountain Dew, which is also made by PepsiCo; some flavors of Powerade and Fresca from Coca-Cola; and Squirt and Sunkist Peach Soda, made by the Dr Pepper Snapple Group.

PepsiCo said it had no plans to remove the ingredient from Mountain Dew and Diet Mountain Dew, both of which generate more than $1 billion in annual sales.

Heather White, executive director at the Environmental Working Group, said of PepsiCo’s decision, “We can only hope that other companies will follow suit.” She added, “We need to overhaul how F.D.A. keeps up with the latest science on food additives to better protect public health.”

Ms. Kavanagh agreed. “I’ve been thinking about ways to take this to the next level, and I’m thinking about taking it to the F.D.A. and asking them why they aren’t doing something about it,” she said. “I’m not sure yet, but I think that’s where I’d like to go with this.”


This post has been revised to reflect the following correction:

Correction: January 26, 2013

An earlier version of this article misspelled the surname of the 15-year-old who started a petition on Change.org to end the use of brominated vegetable oil in Gatorade. She is Sarah Kavanagh, not Kavanaugh.

A version of this article appeared in print on 01/26/2013, on page B1 of the NewYork edition with the headline: PepsiCo Will Halt Additive Use In Gatorade.

Shedd Aquarium looks to slice energy bill









Bob Wengel's job at Shedd Aquarium makes your typical thermostat war seem laughable.


For him, keeping everybody comfortable means manufacturing a 2 p.m. sunset for penguins attuned to the daylight rhythms of South America. It means maintaining 3 million gallons at a cool 58 degrees for blubber-laden whales while also satisfying tiny neon fish that won't tolerate less than 78 degrees.


"The first thing you've got to make sure is that your animals are happy," said Wengel, Shedd's vice president of facilities. "Then, your guests come next and, after that, the people who work here."





Until now it has also meant forking over $1.4 million for electricity and $154,000 for natural gas each year.


The Chicago cultural institution is in the early stages of a massive energy overhaul aimed at cutting energy consumption by half at the 83-year-old building. Under a plan developed pro bono by a public-private consortium, Shedd plans to swap out light bulbs, buy solar panels and sell "negawatts" (getting paid to power down) to the electrical grid to achieve its goal by 2020.


The idea: To create a road map other cultural institutions can follow.


"What we're talking about is bigger than the Shedd," said Mark Harris, president and CEO of the Illinois Science and Technology Coalition, which led the consortium that developed Shedd's energy saving plan.


The task won't be easy. Keeping 32,500 animals healthy, happy and well-lit takes a lot of, well, energy. Part zoo, part art space, the building is a life-support system for 1,500 species operating under the parameters of just about every time zone on the planet. Lighting clings to nearly every floor, ceiling and exhibit, mimicking sunlight, guiding visitors and attractively framing columns.


Most days a small ocean of water is chilled or run through heat exchangers, with excess heat released through cooling towers on the aquarium roof.


Staff members bike to work, diligently compost and exchange unwanted items instead of trashing them, and for years the aquarium has tracked its energy use and made changes where appropriate. Still, the energy consumed at Shedd has it claiming the carbon footprint of an endless 2,200-car traffic jam.


"If you ask me — 'What is sustainability?' — to someone like me who runs a facility, it's energy, waste, water," Wengel said.


In 2011, Shedd used so much energy that, if harnessed, it could power nearly 1,500 homes for a year.


If done right, Shedd's energy-shaving work will be mostly invisible.


Discerning visitors may notice a lighting change in Shedd's main entrance, where 600 light bulbs in the aquarium's octopuslike chandeliers were fitted this week with highly efficient LED bulbs, a change that will cut $7,000 a year off its electricity bills.


The sunlight that appears to grace the colorful, bustling exhibit of 450 reef dwellers just inside the main entrance is actually six LED lights that were first tested for their ability to mimic natural light.


"The solar on the rooftop will be visible," said Tom Hulsebosch, managing director for energy and utilities for West Monroe Partners in Chicago, the consulting firm that helped create Shedd's energy road map. "They might notice the subtlety of the LED lighting, but a lot of it is really behind the scenes."


Shedd's goal is to create an intelligent aquarium that is constantly communicating its energy needs to Wengel and his staff. That means letting them know in real time if a system is using more power than usual and where inefficiencies lie in everything from HVAC systems to life-support pumps.


According to the road map the coalition developed, the aquarium plans to participate in a program that pays big energy users to power down on days when the electric grid is strained by demand from air conditioners. But first that means finding out what in the aquarium can be safely powered down.


To start with, Shedd is installing individual meters on everything from lighting systems to chillers so it can track and analyze how and when energy is being used. From there it can determine which systems could safely be powered down without harming the animals or causing a disruption to patrons, and which could be used or timed differently to save money.


"They cannot compromise experience both on the visitor's side and on the animal side, and they cannot compromise performance because they have a life-support system they have to maintain. So just the fact that they can do this, with those huge barriers, is an incredible example," said Karen Weigert, chief sustainability officer for the city of Chicago, which worked with a coalition that developed the energy plan. Also part of the coalition were the Institute for Sustainable Energy Development and Citizens Utility Board.


The aquarium would simultaneously switch to a pricing scheme that rewards it for using the most energy at the times of day when demand is lowest and electricity prices are cheaper.


Also on the docket: solar panels with batteries for storing excess energy that could be sold back to the electric grid in the same way that power plants sell their power.


The plans are in line with that of Illinois, which in October 2011 approved a 10-year, $2.6 billion upgrade to the electrical grid that serves Shedd and the rest of the Chicago area. Half of that is being spent to create a smart grid that, according to ComEd, will bring 100-year-old electrical grid technology into the digital age, automatically reporting problems, rerouting power and eliminating the need for meter readers.


With a smart grid, Shedd could power up some systems while powering down others, and sell or buy electricity from the grid in real time according to the demands of the electrical grid.


To pay for these changes, Shedd plans to seek government grants and private donations. In time, say coalition members, those investments will reap dividends, financially, educationally and environmentally.


"The Shedd's in a unique position. It's been there for 100 years and it's going to be there for another 100 more; so, when you look at a 15-year return on investment, that's not too bad," Hulsebosch said.

Streak of days without inch of snow finally over




















A relatively meager snowfall created huge headaches for commuters on Friday. CBS's Courtney Gousman capture this video on the Kennedy Expy. around 7:30 a.m. (Source: CBS Chicago)




















































More than an inch of snow fell on Chicago today, finally ending a streak that began 335 days ago.

At 9:30 a.m., 1.1 inches of snow was recorded at O'Hare International Airport since midnight. That's the first day an inch or more of snow has fallen there since last February. The previous record was a stretch of 310 days set in 1940.






This morning's light snow also marks the latest it has gone during a winter before an inch of snow has fallen over a day.

Besides ending record streaks, the snow played havoc with the morning rush hour.

Snow started falling in the Chicago area around 4:45 a.m. Within half an hour, Illinois state police were reporting slick conditions on roads and had already responded to six minor accidents. Shortly after 6 a.m., a nine-car crash was reported near North Avenue on the Kennedy Expressway, but there were no reports of serious injuries.

By 7:15 a.m., state police said they had responded to about two dozen crashes on area expressways.

The snow was expected to end this morning.

“Something like this wouldn’t be newsworthy if it wasn’t for the fact it hasn’t snowed all year,” said Gino Izzi, another meteorologist for the weather service.

Still, the Chicago Department of Streets and Sanitation deployed almost 200 of its 284 plow trucks to clear streets of snow and apply salt to the roads.

"We’re going to be monitoring the weather but at this point we’re looking at snowfall at least through the rush hour," said Anne Sheahan, spokeswoman for Streets and Sanitation.

The next bout of snow is not expected until next week.

"We don’t have much of a chance of snow for the next five or six days," Izzi said.

Al Shabaab says enemies closed its Twitter account






MOGADISHU (Reuters) – Al Shabaab on Friday said its Christian enemies had closed its Twitter account, which the Somali militant group used to parade hostages, mock rivals and claim responsibility for bombings and assassinations.


The group’s official Twitter account, which has thousands of followers, was offline on Friday with a message saying “Sorry, that user is suspended”.






It was not immediately clear why the account, which was created in 2011 under the HSM PRESS Twitter handle, was suspended. The account was still unavailable as of 1233 GMT.


On Wednesday the al Qaeda-aligned rebels used the social media site to threaten to kill several Kenyan hostages and on January 17 announced the execution of a captive French agent after a French commando mission to rescue him failed.


“The enemies have shut down our Twitter account,” al Shabaab‘s most senior media officer, who refused to be named, told Reuters.


“They shut it down because our account overpowered all the Christians’ mass media and they could not tolerate the grief and the failure of the Christians we always displayed (online).”


Al Shabaab wants to impose their strict version of sharia, or Islamic law, across Somalia. However, it has lost significant territory in the southern and central parts of the country in the face of an offensive by African Union troops.


Twitter said it does not comment on individual accounts and the Kenyan government denied it had filed any request for the account to be taken down.


“It’s an emphatic no. We would not try to negotiate or have anything to do with the Al Shabaab. We didn’t even know the account was suspended,” said government spokesman Muthui Kariuki.


Al Shabaab posted on the account on Wednesday a link to a video of two Kenyan civil servants held hostage in Somalia, telling the Kenyan government their lives were in danger unless it released all Muslims held on “so-called terrorism charges” in the country.


“Kenyan government has three weeks, starting midnight 24/01/2013 to respond to the demands of HSM if the prisoners are to remain alive,” the group said.


Despite the closure of the Twitter account, al Shabaab said it would continue to “display the loss and grief of Christians no matter what means we use,” al Shabaab’s spokesman said.

‘Dallas’ returns with J.R. Ewing’s final schemes






NEW YORK (AP) — J.R. Ewing wouldn’t hesitate to cheat his fellow man. He also famously cheated death.


In the second-season finale of “Dallas” back in 1980, he was shot by an unknown assailant in his office and left for dead. But he recovered nicely, and the cliffhanger question that gripped the nation (Who shot J.R.?) was answered that November in an episode seen by 80 million viewers.






This time, J.R. won’t get off so easy. During the second season of TNT’s rebooted “Dallas,” J.R. cashes in his chips and goes to his reward … wherever that may be.


Meanwhile, viewers, however braced they are for J.R.’s demise, will have to reckon with the loss of arguably TV’s greatest villain, and bid farewell to the actor who portrayed him so indelibly and also cheated death for years. Larry Hagman, who died of cancer at 81 the day after Thanksgiving, was diagnosed in 1992 with cirrhosis of the liver from a life of heavy drinking and, three years later, when a malignant tumor was discovered on his liver, successfully underwent a transplant.


This double loss would be a burden for any show to bear. “Dallas,” returning at 9 p.m. EST Monday, comes fully loaded.


“I think viewers want closure,” said Linda Gray, who plays J.R.’s long-suffering ex-wife, Sue Ellen. “They want to mourn Larry Hagman and J.R. Ewing. They want to know they can grieve the fact he won’t be around.”


But all that comes later. With its two-hour season premiere, “Dallas” carries on in familiar fashion, with the expected two-timing, squabbles, a kidnapping revealed, a stolen identity and assorted other mischief.


And never fear: J.R., though visibly frail, continues his reign as a scheming oilman and rascally Ewing patriarch.


“I came over to deliver some muffins to the pretty little secretaries,” he announces on making an unannounced visit to Ewing Energies headquarters before he laments, “Who could have guessed so many would turn out to be MEN? Where’s the sport in THAT?”


In another scene, J.R. shares sly counsel with his son, John Ross, on double-crossing other members of the family: “Love, hate, jealousy: Mix ‘em up and they make a mean martini. And when we take over Ewing Energies, you’ll slake your thirst — with a twist!”


The new “Dallas,” which debuted last June, is stocked with a troupe of young regulars (including Josh Henderson, who plays John Ross), as well as veterans of the original CBS series, notably Gray and Patrick Duffy as J.R.’s ever-upright brother, Bobby. J.R. will appear in a minimum of five or as many as seven of the season’s episodes before he meets his fate.


After that, can “Dallas” survive the dual deaths of its central character and legendary star?


“Larry being gone doesn’t eliminate the influence of the character of J.R.,” Duffy pointed out. Who knows what land mines J.R. will have left behind? “We can find business deals he did or schemes he started that now are coming home to roost, and they can turn up for years to come.”


“Whatever will happen on the show, we will be talking about J.R. Ewing and he will have done things that have a ripple effect,” Gray agreed. “He will always be there.”


“There’s a lot of driving forces on the show — not just J.R.,” added “Dallas” executive producer Cynthia Cidre, who, interviewed by phone a couple of weeks ago, was parked outside a posh Dallas social club where the wake for J.R. was about to be filmed.


She said this season she tried to use Hagman sparingly.


“He was the most delightful man and a total professional,” she said, “but he wasn’t well and we didn’t want to overtax him.”


Now, with his passing, “we want to give J.R., and Larry, the proper send-off.”


But she insisted there had been no contingency plan for how to plot J.R.’s demise in the event Hagman died in mid-season.


“We didn’t have a Plan B, on purpose,” said Cidre. “We just knew that we had Larry, so let’s use him, let’s enjoy him, and if something happens, we’ll scramble and fix it. I had great faith in the writers’ room. We knew the day might come and what we would do then: Figure it out.”


That day came in late November when she got a call from Duffy. “He told me, ‘Larry’s in the hospital and it isn’t good. He’s saying goodbye.’ In 24 hours we had fixed one of the scripts. We had two more scripts that had to be adjusted, and then this episode we’re shooting now, the Goodbye Episode.”


Roughly 85 percent of the season’s story line remains intact, she said, supplemented by the death of J.R. and the mystery surrounding it: Who Killed J.R.?


“The mystery has all the machinations of a great J.R. business deal, as opposed to a whodunit,” said Duffy. “Cynthia constructed a really interesting plot, of which I know Bobby’s portion” — including whodunit — “but I don’t know other stuff.”


“We all know, up to a point,” Gray said. “But they’ve got secret pages that we’ve not seen.”


“I hope that we have come up with something really wonderful and enticing,” said Cidre, “and by the time you’re done watching episode 208, which I call the Funeral Episode, I hope you’re saying, ‘Omigod, I didn’t see that coming, and I can’t wait to watch the rest of the season.’”


The mystery, she said, will continue through episode 15, “with a giant, delightful, delicious climax in the season finale.”


To get there, shooting continues until April on the Dallas set, where, even two months after Hagman’s passing, “I’m lonely because my best friend isn’t there to play with,” Duffy said. “I was with him from 1978 until his final hours in the hospital. But I have no regrets. Every day I think of him and smile.”


“I keep expecting him to walk in the door,” Gray said. “He’s so missed. But his presence is everywhere!”

Well: Ask Well: Squats for Aging Knees

You are already doing many things right, in terms of taking care of your aging knees. In particular, it sounds as if you are keeping your weight under control. Carrying extra pounds undoubtedly strains knees and contributes to pain and eventually arthritis.

You mention weight training, too, which is also valuable. Sturdy leg muscles, particularly those at the front and back of the thighs, stabilize the knee, says Joseph Hart, an assistant professor of kinesiology and certified athletic trainer at the University of Virginia, who often works with patients with knee pain.

An easy exercise to target those muscles is the squat. Although many of us have heard that squats harm knees, the exercise is actually “quite good for the knees, if you do the squats correctly,” Dr. Hart says. Simply stand with your legs shoulder-width apart and bend your legs until your thighs are almost, but not completely, parallel to the ground. Keep your upper body straight. Don’t bend forward, he says, since that movement can strain the knees. Try to complete 20 squats, using no weight at first. When that becomes easy, Dr. Hart suggests, hold a barbell with weights attached. Or simply clutch a full milk carton, which is my cheapskate’s squats routine.

Straight leg lifts are also useful for knee health. Sit on the floor with your back straight and one leg extended and the other bent toward your chest. In this position, lift the straight leg slightly off the ground and hold for 10 seconds. Repeat 10 to 20 times and then switch legs.

You can also find other exercises that target the knees in this video, “Increasing Knee Stability.”

Of course, before starting any exercise program, consult a physician, especially, Dr. Hart says, if your knees often ache, feel stiff or emit a strange, clicking noise, which could be symptoms of arthritis.

Burnt circuit boards snag Japan's 787 probe

The chairman of the NTSB said the seriousness of two recent Boeing Dreamliner battery incidents "cannot be understated." (Source: CBS)









A device seen as key to explaining why a Boeing Co. 787 Dreamliner jet made an emergency landing in Japan last week is burnt and unlikely to provide safety inspectors with data they need, said a person with knowledge of the ongoing investigation.

Circuit boards that control and monitor the performance of the plane's lithium-ion battery unit were charred and may be of little use to the teams investigating why the battery effectively melted, forcing safety investigators to scramble for possible clues from other components in the plane's electronics, said the person, who didn't want to be named as the probe is ongoing.






Aviation authorities in Japan face a painstaking reconstruction that may take months before they can unravel what caused one of the batteries to overheat, triggering warnings in the plane's cockpit.

That relatively inexpensive circuit boards may be keeping $10 billion worth of futuristic aircraft idle underscores how dependent the Boeing jet is on advanced electronics rather than more traditional, but less fuel-efficient, parts, experts said.

"The circuit board (system) is badly damaged. We'll see how much we can learn from examining it, but we'll also have to look at other recording devices on the aircraft to try and find out what happened," the person with direct knowledge of the investigation told Reuters.

BATTERY "BRAIN"

The circuit boards, known as the battery monitoring unit, are the "brains" of the battery, experts said. About the size of a laptop computer, the boards monitor functions of the lithium-ion battery's eight cells and feed this information to the charger. That effectively makes the boards responsible for preventing a battery from overcharging.

One key question for safety investigators is how the battery's eight individual cells became volatile even though the overall voltage to the battery was steady and didn't exceed the 32-volt capacity, officials have said. That data is not recorded in the Dreamliner's "black box" flight-data recorder.

U.S, Japanese and Boeing representatives have this week been at the Kyoto headquarters of GS Yuasa Corp, which makes batteries for the 787, looking at everything from manufacturing quality to technical standards.

The main battery from the All Nippon Airways flight is still at the GS Yuasa plant, where it is being cleaned and disassembled for further checks. Once they are done, Japanese safety officials plan to take the damaged circuit boards to the manufacturer, Fujisawa-based Kanto Aircraft Instrument, for a detailed inspection.

All 50 of Boeing's Dreamliners in service were grounded last week after the ANA-operated flight's emergency landing on a domestic flight. That followed an auxiliary battery fire in a Japan Airlines Co. Ltd 787 parked at Boston Airport.

"There is a possibility that a fire destroyed the elements that caused the problem and if so, it will become difficult to investigate the cause," said Hideaki Horie, project professor at the Institute of Industrial Science at Tokyo University.

Horie said Boeing should re-think the design of the battery safety and data recovery system even while it investigates what caused the recent Dreamliner incidents.

The 787 uses two lithium-ion batteries, which are about twice as large as a car battery. The batteries weigh less than a conventional battery and provide more power. They are Boeing's first step toward hybrid power systems like those used by automakers General Motors Co. and Toyota Motor Corp .
