Panasonic sees $5.5 billion annual loss, worst in a decade (Reuters)

TOKYO (Reuters) ? Japanese electronics maker Panasonic Corp (6752.T) forecast an annual net loss of 420 billion yen ($5.5 billion), its biggest in a decade, as it cut unprofitable businesses deeper and faster than first planned, while battling a soaring yen and weak demand in the United States and Europe.

Panasonic accelerated the pace of restructuring as it races to shake off losses at its TV unit -- a problem it shares with rival Sony (6758.T) -- and strips out overlapping businesses after its buyout of subsidiary Sanyo.

In April, Panasonic said it would cut 17,000 jobs by March 2013, but the maker of Viera televisions and Lumix cameras announced on Monday it now expects to reach its goal of slimming its work force to 350,000 or fewer a year ahead of schedule.

Panasonic said it will stop liquid-crystal panel production at its Mobara plant near Tokyo and is canceling its plans to ship plasma-panel manufacturing equipment from another mothballed plant to Shanghai to start production there, as it aims to turn a profit on TVs in its next fiscal year.

One analyst said the dramatic slide in profits might not lead to a sell-off of Panasonic's stock.

"The net loss of 420 billion yen includes an increase in the cost of restructuring. It has lowered the assumed exchange rates to 76 yen, which gives the company some buffer even if the dollar slips from the current level after today's intervention," said Hiroyuki Fukunaga, CEO of Investrust.

"So even though it is reporting a loss, the market may think all the negative factors have been priced in, especially given that its share price has fallen about a third from around 1,200 yen at the beginning of this year."

Panasonic said it would incur 514 billion yen in restructuring costs, about half of it in the TV business, for the year to March, compared with an earlier forecast of 110 billion yen.

The Japanese government intervened in the currency market for the second time in less than three months after the yen hit another record high against the dollar on Monday, selling yen to counter speculative trading that officials say is hurting the world's No.3 economy.

Panasonic's annual loss, which will be its second biggest ever, compares with the company's previous forecast for a net profit of 30 billion yen in the year to March 2012 and last year's net profit of 74 billion yen.

Shares of the company closed 2.1 percent lower before the results. They have fallen 31 percent so far this year, compared with a 13 percent decline in the broader market (.N225).

'BIRTH PANGS OF NEW STRATEGY'

"What we need to tackle is the television and related semiconductor businesses," Chief Financial Officer Makoto Uenoyama told reporters.

"If we downsize these, our profits will be completely different," he added, calling the forecast losses "the birth pangs of switching to a new strategy." Panasonic is trying to switch emphasis from consumer technology to energy and environmental technology, such as rechargeable batteries.

The company cut its full-year operating profit forecast to 130 billion yen from 270 billion yen.

That is far below market expectations of a 225 billion yen profit, based on the average estimate of 21 analysts polled by Thomson Reuters I/B/E/S.

It also slashed its estimate for annual TV sales to 19 million sets from 25 million.

Sony said on Monday it will split its television business into three divisions to make operations more accountable as part of efforts to turn around the loss-making business.

For July-September, Panasonic reported an operating profit of 42 billion yen, beating its own forecast of 4.4 billion yen profit, but falling short of analysts' average estimate of 50 billion yen. It had reported an operating profit of 85.2 billion yen a year earlier.

For the remainder of the business year, Panasonic estimates a dollar-yen rate of 76 yen and a rate of 105 yen against the euro.

($1 = 75.760 Japanese yen)

How to unbalance nothingness

Friday, October 28, 2011

Nothingness ? this is the research subject-matter of a team of theoretical physicists from the Universities Jena (Germany) and Graz (Austria). "The ground state of our world can't be described by the absence of all matter," Professor Dr. Holger Gies from the Institute of Theoretical Physics of the Friedrich-Schiller-University Jena and the Helmholtz-Institute Jena explains. "This so-called quantum vacuum rather turns out to be a complex state of constantly fluctuating quantum fields with physical properties."

The world-wide community of physicists is hoping to be able to witness a particularly spectacular characteristic in a few years' time: the spontaneous decay of the vacuum into pairs of particles of matter and antimatter in super strong electric fields. Due to the new research results of the Austro-German team of physicists, this goal came a few steps closer.

Although first theoretical consideration concerning the spontaneous decay of the vacuum dates back to the year 1931, its comprehensive understanding is still in its infancy. ?A great challenge in modern theoretical physics is the description of quantum fields out of equilibrium," Professor Gies explains. "We are facing this problem in phase transitions in the early Universe as well as in many experiments in solid state physics." Therefore experimental proof of the vacuum decay ? as it might be delivered by high intensity lasers in the near future ? will provide knowledge exceeding this particular field.

The scientists from Graz and Jena now succeeded calculating the time evolution of the vacuum decay in detail. "Even we were surprised by the results," Professor Gies confesses. According to the results particles of matter and antimatter behave in a novel self-focusing way and therefore the possibility of discovering them is higher than expected. "The quantum vacuum has already had some surprises in store," says the Heisenberg-Professor for Theoretical Physics. "To unbalance this nothingness could develop into a new prolific field of research."

Brazil's ex-president Lula has throat cancer (Reuters)

SAO PAULO (Reuters) ? Brazil's popular former president Luiz Inacio Lula da Silva was diagnosed with throat cancer on Saturday, casting doubt on his political future in Latin America's largest economy.

Lula, as he is universally known, is a former metalworker and union leader who rose from poverty to become Brazil's first working-class president. He led the country between 2003 and 2010, a period of robust economic growth in which more than 20 million Brazilians were lifted out of poverty and joined the middle class.

Speculation has swirled that Lula -- who remains immensely popular in Brazil -- could run for the presidency again in 2014 if President Dilma Rousseff, his political protegee, were to decide not to seek re-election.

Lula, who turned 66 this week, was diagnosed with a malignant tumor in the larynx and will start chemotherapy in the coming days, according to Sao Paulo's Sirio Libanes Hospital. Rousseff herself was treated for cancer at the same medical center before taking office in January.

Dr. Artur Katz, an oncologist on Lula's medical team, told Brazilian newspaper Folha de S.Paulo that the tumor was "not very big" and that "the odds of a cure are excellent."

Chemotherapy was chosen over surgery to preserve the functions of Lula's larynx, or voice box, he said.

Dr. Paulo Hoff, another oncologist on the team treating Lula, told local news Web site ig.com.br that the tumor was localized and had not spread through the neck or to his lymph nodes. He said Lula would also undergo radiation therapy.

"He's a fighter," Finance Minister Guido Mantega said after visiting Lula in hospital. "There's no metastasis. Nothing has spread to other organs and everything was detected.

Lula left the hospital in the early evening and is expected to return for outpatient treatment starting on Monday.

POLITICAL ROLE

Lula, who left office with a sky-high approval rating of 87 percent, could play a vital role in next year's municipal elections, helping stump for candidates from his left-leaning Workers' Party, known as the PT.

But it is in the next presidential election in 2014 that Lula's role could be key -- whatever that role ultimately is.

"The presence of Lula is an extremely important ace in the hole for the Workers' Party," said Latin America analyst Christopher Garman of the Eurasia consultancy in Washington.

Whether Lula campaigns for Rousseff or, should she falter, runs himself, Garman said, his participation "guarantees the opposition have a hard time reaching office in 2014."

More recently, Lula's presence has been a boost for Rousseff because it "means that allies were never going to abandon ship," Garman said. "He's an extremely important political hedge for this administration."

Since leaving office Lula has done little to lower his profile, founding a public policy institute and traveling the world speaking on democracy.

He's also kept a hand in domestic politics, privately advising Rousseff on a series of corruption scandals that have rocked her government. Six ministers have so far left her administration this year, five of them over ethics breaches.

Brazilians flooded the social media site Twitter with well-wishes, prayers and more. "We'll keep an eye out for you in 2018," one tweeter said.

CIGAR SMOKER

A folksy leader who has suffered occasional health problems over the years, Lula is a smoker with a weakness for cigarillos, or baby cigars. He was also known as a drinker, which contributed to his image as a man of the people.

Both drinking and smoking boost the chances of throat cancer, according to the U.S. National Cancer Institute.

Dozens of reporters and TV crews gathered outside the hospital to try to get a glimpse of Lula. The news dominated Brazil's television and radio programs, with one commentator calling the diagnosis a "bombshell."

Rousseff issued a statement wishing her predecessor a speedy recovery, calling him a "symbol and an example" for all Brazilians. An aide said Rousseff, who was plucked from relative obscurity by Lula and groomed to succeed him, planned to visit the former president on Monday.

Lula is particularly known for his trademark beard and gruff voice, whose roughness seemed to mirror his own unpolished edges. But he recently had noticed more gruffness in his voice as well as some discomfort, according to local radio and television reports.

A politician with a Midas touch among voters -- particularly among the lower-income classes that make up the PT's base -- Lula helped bolster Brazil's influence on the world stage during his eight years in office.

Young people lead the way in communities working together

As police and politicians seek fast-track solutions to the recent violence on the streets of England's cities, student volunteers and teachers from the University of Central Lancashire (UCLan) have started a new project, 'Global Youth Leaders', which is part of a long-term programme using young people as mentors in deprived communities in Britain and abroad.

The project, which focuses on West Cumbria, will feature Culture Shock! workshops as part of the Economic and Social Research Council's (ESRC) Festival of Social Science in October 2011. Martial arts classes, Asian dance, sari fittings, turban tying, curry cooking, stir-fries, baking naan bread - such events will enable a hundred young people from Whitehaven and Cleator Moor to connect with communities and cultures outside of their own.

The workshops will be run by student volunteers from UCLan's Centre for Volunteering and Community Leadership, who have Pakistani, Indian, Bengali, Chinese and Caribbean backgrounds. They will be working with the young people while they discuss their cultures and identities while cooking, making crafts and playing sports.

"The value of this approach is the opportunities it provides for young people to mix with their equals and teachers from a diverse range of cultures and backgrounds. We have found it really effective in breaking down pre-conceived views and broadening knowledge and understanding." says Dr Alethea Melling who heads the project.

Whitehaven and Cleator Moor are among the ten per cent of most deprived areas in England. They are also among the most divided. Teenage alcohol and drug misuse leads to problems of anti-social behaviour; there is also deep-rooted racism in these communities, which is increased by their isolation; and young people have little opportunity to explore other cultures or to interact with people from different social and ethnic backgrounds.

However, Dr Melling is confident that this project, which promotes intercultural connection through peer education, can offer a way forward. The Centre has a proven track record of working with people in deprived communities all over Britain, including with residents of Burnley after the disturbances in 2001.

"We have been increasingly aware that main sources of development for community champions are around 'training' or events whereby policy and practice is discussed in an uncritical manner," concludes, Dr Melling. "Given the right support, young people have the genius and the dynamism to direct and effect positive change within their communities."

Dr Melling and her colleagues are working with the North West Community Activist Network and other partners to set up an International Institute for Community Leadership. The IICL will provide an independent forum where community activists can work with academics to explore issues affecting them and to gain a critical knowledge of the theory that underpins governmental policy and practice.

The Most Effective Habit For Entrepreneurs

7 Habits coverThere was a girl at a party, Ona, who then started telling me how she met her current boyfriend. She just simply told him she liked him. I was insanely jealous right then of this guy. Here was this beautiful, hysterically funny girl who told a guy she liked him and now he was having regular sex with her. That doesn?t happen, right? It never happened to me. I sat there nodding, not being able to say anything but thinking, what if she said, ?I like you? to me right then. I would?ve been happy. Instead, I got depressed and went to sit on the stairs. There was another girl there. She was crying.I tried to comfort her by telling her I was an artist.

UFC 137 video: Diaz says Penn is the much tougher fight over GSP

Nick Diaz knows he has a big challenge in front of him on Saturday night at UFC 137. In fact, he believes it's a tougher fight than the one he's was originally scheduled for against Georges St-Pierre.

"I wouldn't have picked this fight for sure," Penn told HDNet's Inside MMA. "I think he'll probably try to slip the jab and throw the overhand right (then) make a body lock or (go for a) single leg takedown. Maybe push me against the fence."

Diaz knows he could ward off the Penn attack with a safety-first mentality, but that's not in his DNA.

"I'm going to have to deal with a lot of that stuff. It's B.J. Penn so it's a real difficult fight especially for somebody like me who's going to go and try to fight, and not try to hold him and win rounds," said Diaz.

Diaz truly believes Penn is a tougher fight than the UFC welterweight champ would've presented, but you can hear he's still wants thate on an eventual GSP tilt.

"If I lose to B.J. Penn, he's either going to take me out with a right hand or he's going to go on top in some way and end in some position. He'll probably want to put a mount, take the back and put a choke. You know, finish the fight," Diaz said.

"Georges would look to just do enough to win the fight. Every fight that he does (is like that). I doubt that would've worked out with me the same way it does with a lot of the other fighters. I have the tool and what it takes to make something other than that happen in there."

Even though it's a three-rounder on Saturday, Diaz believes his big advantage may be in the cardio department. Penn has had stamina issues int he past at 170 pounds.

Report: Facebook user jailed for inciting UK riots

A U.K. court has jailed a 22-year-old Facebook user who urged youths to "put Manchester on the map" by rioting during the summer?s unrest in cities across Britain, a newspaper reported.

    7. Breast cancer causes foot-in-mouth disease in others

The judge in the case of Philip Scott Burgess ruled that the organizers of the riots shared guilt with the participants, London?s Telegraph newspaper reported Friday.

Burgess was jailed for three years after pleading guilty to publishing written material to stir up racial hatred and encouraging or assisting the commission of a riot, the paper said.

As civil disturbances engulfed Birmingham, Liverpool and London in August, Burgess exhorted others to "start riot'n" and "put Manchester on the map," the newspaper reported.

Within hours, looting began in a popular shopping area in Salford, Greater Manchester, the Telegraph said. Shortly afterward, the rioting spread to the center of Manchester.

Burgess also posted racist messages about the ethnicity of the rioters, the newspaper said.

'Public pledge'
"At the time of the disorder, we made a public pledge to our communities that we would pursue not just those involved in looting, violence or arson, but those who used social networking sites to stir up trouble and encourage others to get involved,? the Telegraph quoted Assistant Chief Constable Ian Hopkins as saying.

"The disorder brought shameful scenes to our cities and those who used social networking sites to organize what happened are just as responsible as those who physically took part,? Hopkins said, according to the newspaper.

The four days of rioting, triggered by a fatal police shooting Aug. 4 in north London?s Tottenham neighborhood, were the worst civil disturbances to hit Britain since the 1980s. Five people were killed and scores of stores were looted and buildings burned in several cities. More than 2,500 shops and businesses were targeted by the looters and vandals, with more than 230 homes being hit by burglars or vandals.

Reuters contributed to this report.

Dwarf planet sized up accurately as it blocks light of faint star

In November 2010, the distant dwarf planet Eris passed in front of a faint background star, an event called an occultation. These occurrences are very rare and difficult to observe as the dwarf planet is very distant and small. The next such event involving Eris will not happen until 2013. Occultations provide the most accurate, and often the only, way to measure the shape and size of a distant Solar System body.

The candidate star for the occultation was identified by studying pictures from the MPG/ESO 2.2-metre telescope at ESO's La Silla Observatory. The observations were carefully planned and carried out by a team of astronomers from a number of (mainly French, Belgian, Spanish and Brazilian) universities using among others the TRAPPIST [1] (TRAnsiting Planets and PlanetesImals Small Telescope, eso1023 - http://www.eso.org/public/news/eso1023/) telescope, also at La Silla.

"Observing occultations by the tiny bodies beyond Neptune in the Solar System requires great precision and very careful planning. This is the best way to measure Eris's size, short of actually going there," explains Bruno Sicardy, the lead author.

Observations of the occultation were attempted from 26 locations around the globe on the predicted path of the dwarf planet's shadow including several telescopes at amateur observatories, but only two sites were able to observe the event directly, both of them located in Chile. One was at ESO's La Silla Observatory using the TRAPPIST telescope, and the other was located in San Pedro de Atacama and used two telescopes [2]. All three telescopes recorded a sudden drop in brightness as Eris blocked the light of the distant star.

The combined observations from the two Chilean sites indicate that Eris is close to spherical. These measurements should accurately measure its shape and size as long as they are not distorted by the presence of large mountains. Such features are, however, unlikely on such a large icy body.

Eris was identified as a large object in the outer Solar System in 2005. Its discovery was one of the factors that led to the creation of a new class of objects called dwarf planets and the reclassification of Pluto from planet to dwarf planet in 2006. Eris is currently three times further from the Sun than Pluto.

While earlier observations using other methods suggested that Eris was probably about 25% larger than Pluto with an estimated diameter of 3000 kilometres, the new study proves that the two objects are essentially the same size. Eris's newly determined diameter stands at 2326 kilometres, with an accuracy of 12 kilometres. This makes its size better known than that of its closer counterpart Pluto, which has a diameter estimated to be between 2300 and 2400 kilometres. Pluto's diameter is harder to measure because the presence of an atmosphere makes its edge impossible to detect directly by occultations. The motion of Eris's satellite Dysnomia [3] was used to estimate the mass of Eris. It was found to be 27% heavier than Pluto [4]. Combined with its diameter, this provided Eris's density, estimated at 2.52 grams per cm^3 [5].

"This density means that Eris is probably a large rocky body covered in a relatively thin mantle of ice," comments Emmanuel Jehin, who contributed to the study [6].

The surface of Eris was found to be extremely reflective, reflecting 96% of the light that falls on it (a visible albedo of 0.96 [7]). This is even brighter than fresh snow on Earth, making Eris one of the most reflective objects in the Solar System, along with Saturn's icy moon Enceladus. The bright surface of Eris is most likely composed of a nitrogen-rich ice mixed with frozen methane as indicated by the object's spectrum coating the dwarf planet's surface in a thin and very reflective icy layer less than one millimetre thick.

"This layer of ice could result from the dwarf planet's nitrogen or methane atmosphere condensing as frost onto its surface as it moves away from the Sun in its elongated orbit and into an increasingly cold environment," Jehin adds. The ice could then turn back to gas as Eris approaches its closest point to the Sun, at a distance of about 5.7 billion kilometres.

The new results also allow the team to make a new measurement for the surface temperature of the dwarf planet. The estimates suggest a temperature for the surface facing the Sun of -238 Celsius at most, and an even lower value for the night side of Eris.

"It is extraordinary how much we can find out about a small and distant object such as Eris by watching it pass in front of a faint star, using relatively small telescopes. Five years after the creation of the new class of dwarf planets, we are finally really getting to know one of its founding members," concludes Bruno Sicardy.

[4] Eris's mass is 1.66 x 10^22 kg, corresponding to 22% of the mass of the Moon.

[5] For comparison, the Moon's density is 3.3 grams per cm^3, and water's is 1.00 gram per cm^3.

[6] The value of the density suggests that Eris is mainly composed of rock (85%), with a small ice content (15%). The latter is likely to be a layer, about 100 kilometre thick, that surrounds the large rocky core. This very thick layer of mostly water ice is not to be confused with the very thin layer of frozen atmosphere on Eris's surface that makes it so reflective.

[7] The albedo of an object represents the fraction of the light that falls on it that is scattered back into space rather than absorbed. An albedo of 1 corresponds to perfect reflecting white, while 0 is totally absorbing black. For comparison, the Moon's albedo is only 0.136, similar to that of coal.

ESO, the European Southern Observatory, is the foremost intergovernmental astronomy organisation in Europe and the world's most productive astronomical observatory. It is supported by 15 countries: Austria, Belgium, Brazil, the Czech Republic, Denmark, France, Finland, Germany, Italy, the Netherlands, Portugal, Spain, Sweden, Switzerland and the United Kingdom. ESO carries out an ambitious programme focused on the design, construction and operation of powerful ground-based observing facilities enabling astronomers to make important scientific discoveries. ESO also plays a leading role in promoting and organising cooperation in astronomical research. ESO operates three unique world-class observing sites in Chile: La Silla, Paranal and Chajnantor. At Paranal, ESO operates the Very Large Telescope, the world's most advanced visible-light astronomical observatory and two survey telescopes. VISTA works in the infrared and is the world's largest survey telescope and the VLT Survey Telescope is the largest telescope designed to exclusively survey the skies in visible light. ESO is the European partner of a revolutionary astronomical telescope ALMA, the largest astronomical project in existence. ESO is currently planning a 40-metre-class European Extremely Large optical/near-infrared Telescope, the E-ELT, which will become "the world's biggest eye on the sky".

Super-social gene may hold clues to autism, other disorders

Scientists may soon understand the link between genes and human behavior, including autism, thanks to a major effort to study Williams syndrome, a rare genetic disorder that causes people to be so excessively friendly, there's no such thing as a stranger.

Slice Is a Brilliant Companion to Your Online Shopping [Shopping]

Slice Is a Brilliant Companion to Your Online ShoppingWith access to your email inbox, webapp Slice automatically analyzes emails containing order information from your online shopping and organizes all your purchases in one place, giving you quick access to tracking packages, purchase history, and price-drop tracking for everything you buy online. It's a brilliant idea.

Here's how it works:

  1. Sign up at Slice using your Gmail or Yahoo account.
  2. Give Slice permission to scour your Gmail inbox for purchases. (Slice uses OAuth to access your account, so you never give them your password; if you're a Gmail user, you can revoke Slice's permission to use your inbox at any time here.)
  3. Slice will run an initial scan of your recent purchases and import them into the Slice homepage.

That's all there is to it. Once you've got Slice set up, it will automatically add new purchases to your purchase history on Slice. Aside from giving you a fairly comprehensive view of your online purchase history (no matter where you bought something), here are the three great things Slice does for you:

  • Tracks your shipments from one interface: The homepage displays your most recent purchases, but you can click on the map icon to track your shipment across the country. Alternately, just visit the Track Shipments page to click through all your most recent shipments to see where your new gizmo is.
  • Notifies you of price drops: As Slice puts it:

    Don't you hate it when you buy something awesome and then the next week, you see the same item on sale for 20% less? So do we. So we're going to help you do something about it.

    When Slice detects a price drop from select merchants that honor price adjustments, we'll send you a notification.

  • Search and backup your purchase history: The site lets you search your purchase history, find your order number, display return by dates, view the original email purchase confirmation, and so on. It also shows you how much you spend online, which depending on your habits, may be uncomfortable but helpful.

If Slice misses any purchases (that is, it doesn't automatically identify an email as a purchase notification from an online vendor), you can just forward the purchase email to orders@goslice.com and they'll automatically add it to your account. In that way, Slice is a whole lot like our favorite travel companion, TripIt, down to the automatic itinerary import.

The only downside to Slice on first glance is that it could use a little more polish to its web site to make the whole experience friendlier. But it's a helluva start, and it's certainly going to be where I track my purchases for the foreseeable future.
