Goodbye to Berlin



Business bosses are growing impatient with a drifting government













“I SUPPORT the euro, but not at any price,” said Wolfgang Reitzle, chief executive of Linde, an industrial-gas producer, in a recent interview. He is not alone. Many German business leaders are wondering if the apparently never-ending euro-zone bail-outs, to which Germany is the biggest contributor, are beginning to outweigh the (considerable) advantages of the single-currency area.
Their concerns are aggravated by what they see as political drift in Berlin. Many German bosses, say those close to them, have lost faith in the ability of Angela Merkel’s government to steer Europe out of trouble. Looking towards Berlin from their fastnesses in the Ruhr and southern Germany, they see only weak leadership, perverse decision-making and poor communication. These days many no longer bother making the trip to the capital.

Now differences over the euro are adding to the headache. In September Mrs Merkel must secure parliamentary ratification of a deal she agreed with other euro-zone leaders in July to expand the powers of the single currency’s bail-out fund. Dissent from some FDP deputies, and even from within the CDU itself, could force her to rely on support from the opposition.
Many business leaders complain that the government, which yokes together the conservative Christian Democrats (CDU) with the pro-business Free Democrats (FDP), is plagued by in-fighting. The CDU wants to keep taxes high to help reduce the budget deficit. But the FDP insists that reducing the burden on taxpayers was part of the deal they agreed when the parties formed their supposed “dream-team” after elections in September 2009.
Aside from the euro, bosses’ biggest beef is the government’s decision, in May, to close all of Germany’s nuclear-power stations by 2022. The move followed a moratorium initiated by the government in the wake of the nuclear disaster in Japan, just before an important regional election that the CDU feared losing. Many saw it as an unprincipled U-turn. Only last autumn the government had agreed to extend the lives of some nuclear-power stations by an average of 12 years. The new policy was thought up “without true awareness of the consequences,” said Dieter Zetsche, head of carmaker Daimler, in an outspoken interview with Bild, a tabloid. Most bosses think that they were not consulted properly, if at all.
Some consequences of the new nuclear policy became apparent on August 9th when RWE, a big energy firm, said the move had cost it €900m ($1.3 billion) in the first six months of 2011. A day later E.ON, another power firm, noted an “adverse effect” from the policy worth €1.7 billion in the second quarter alone; it said it might have to cut up to 11,000 jobs. Bayer, a chemical firm, said it was considering moving production to countries where electricity prices have a more certain future.
Some in the business world are starting to feel nostalgic for earlier governments they think were better at getting things done. Before joining forces with the FDP Mrs Merkel led a “grand coalition” with the Social Democrats (SPD). In December 2008, with the world’s economy sagging, she summoned senior German businessmen to discuss a set of stimulus measures, including subsidies for retaining staff on shorter hours rather than laying them off. The package worked.
Some even look back fondly to Gerhard Schröder’s “red-green” coalition, which ruled Germany between 1998 and 2005. Mr Schröder was nicknamed the Genosse der Bosse(bosses’ buddy) for seeing through unpopular labour and tax reforms. Many now credit those with ensuring that Germany got through the economic crisis relatively unscathed.
Today German bosses feel that they have few buddies in Berlin. Some of the biggest pro-business officials in the ministries have been assigned to new jobs. These include Markus Kerber, formerly Mrs Merkel’s chief economic adviser and now director of the Federation of German Industry, and Jens Weidmann, once Mrs Merkel’s chief financial adviser and now head of the Bundesbank.
Business leaders respect Wolfgang Schäuble, the finance minister. But he too is about to lose good staff: Jochen Sanio, head of BaFin, the financial watchdog, and Rolf Wenzel, who runs Mr Schäuble’s financial-markets department, are both on the way out. The glum mood is not helped by reservations about Philipp Rösler, the new FDP leader, as economy minister.
The business associations, most of them sitting in Berlin, feel that government is no longer listening. So do senior bankers. In May, sensing the breakdown in communication, Mr Reitzle suggested creating a platform for national discussion on the sorts of important topics that are otherwise left to television talk-shows.
Yet however disgruntled Germany’s business leaders may be, they are not the only cause for Mrs Merkel’s concern. During her recent walking holiday in the mountains of south Tyrol a number of CDU heavyweights, fearing drift and a loss of the party’s identity, called for an emergency party congress. A poll of members of the CDU and its sister party, the Christian Social Union (CSU), found that most are against bailing out euro-zone countries. The German press, meanwhile, has been wringing its hands over the European Central Bank’s decision to buy Spanish and Italian bonds (see article). Many Germans see the purchases as a dangerous deviation from orthodox monetary policy, and a step towards fiscal support.
Unlike her counterparts in France, Britain and Spain, Mrs Merkel did not feel compelled by crisis at home to cut short her holiday. She insists that the decisions taken at the July summit are sufficient to preserve the euro. Her grip on her party still seems secure. But she has returned to Berlin facing a worryingly high in-tray.

பொய் சொல்லக்கூடாது பாப்பா

ஒரு திருடன், கோடீஸ்வரனாகி செட்டிலாக நினைத்தான்.  அவனது அம்மாவுக்கு உடல்நிலை  சரியில்லாமல் போனது. நீ இன்னும் பெரிய திருடனாக மாறி நிறைய சம்பாதிப்பாய், என ஆசிர்வதித்தாள்.  திருடனுக்கு சந்தோஷம் தாங்கவில்லை. அதே நேரம் மகனிடம்,எனக்காக ஒன்று செய்வாயா? என்றாள். என்ன என்ற அவனிடம், பொய் சொல்லமாட்டேன் என உறுதி கொடு, என்றாள். இவனும் சத்தியம் செய்து கொடுத்து விட்டான். அம்மா இறந்து போனாள். அடுத்த சில நாட்களிலேயே அரண்மனை கஜானாவில் திருடச் சென்றான். வழியில் குதிரையில் வந்த ஒருவனைப் பார்த்தான். எங்கே போகிறாய்? என்றான். பொய் சொல்வதில்லை என்ற சத்தியம் செய்திருந்ததால்,திருடப்போகும் விஷயத்தை மறைக்காமல் சொன்னான்.

வந்தவன் அவனிடம், அப்படியானால், நானும் வருகிறேன். திருடுவதில் ஆளுக்குப் பாதி, என்றான். திருடன் ஒப்புக்கொண்டான். கஜானாவிற்கு சென்ற அவர்களில், குதிரையில் வந்தவன் வெளியே நின்று யாரும் வருகிறார்களா என்று கண்காணிக்க, திருடன் உள்ளே புகுந்து ஒரு பெட்டியை உடைத்தான். மூன்று வைரக்கற்களை எடுத்தான். வைரக்கல்லை உடைத்து ஒன்றரை வீதம் பங்கு வைத்தால் சரியாக இருக்காது என்பதால், இரண்டை எடுத்து வந்தான். ஆளுக்கொன்றாக பிரித்துக் கொண்டு போய்விட்டனர். மறுநாள் விஷயம் வெளியாக மந்திரி கஜானாவிற்கு சென்றார். ஒரு கல் மட்டும் இருந்தது. ஆசையில், அதை எடுத்து ஒளித்து வைத்துக் கொண்ட அவர், மூன்றுமே திருட்டு போய் விட்டதாக மன்னனிடம் சொல்லிவிட்டார். திருடன் கைது செய்யப்பட்டான்.

பொய் சொல்வதில்லை என சத்தியம் செய்திருந்ததால் நடந்த உண்மையை விசாரணையின் போது சொல்லிவிட்டான். மன்னனும் அவனிடம்,நீ சொல்வது உண்மையே. அன்று குதிரை மீது திருடன் போல் வேடமிட்டு வந்தது நான் தான். நீ இரண்டு கல்லை எடுத்து ஒன்றை என்னிடம் கொடுத்து விட்டாய். இன்னொன்றை இந்த மந்திரி எடுத்து ஒளித்து வைத்ததும் எனக்கு தெரியும், என்றவன் மந்திரியை சிறையில் தள்ளினான். திருடனின் உண்மைத் தன்மையைப் பாராட்டி மந்திரியாக்கி விட்டான். இதனால் தான், நம்ம பாரதி பொய் சொல்லக்கூடாது பாப்பா என்று இளைய தலைமுறைக்காக எழுதி வைத்தார். நன்றி தினமலர்

The First Fully Stretchable OLED

UCLA device is a step toward video displays and phones that could swell or shrink.
  • BY KRISTINA GRIFANTINI
Stretchable electronics promise video displays that could be rolled up and tucked into a shirt pocket, or cell phones that could swell or shrink. Electronic sheets that could be draped like cloth would be a boon for robotic skin and embedded medical devices. 
Now engineers at the University of California, Los Angeles, have taken a step toward these handy electronics by creating the first fully stretchable organic light-emitting diode (OLED). Previously, researchers had only been able to create devices that are bendable but can't stretch, or stretchable pieces that connect smaller, rigid LEDs.
One challenge in creating stretchable electronics is to develop an electrode that maintains its conductivity when deformed. To achieve this property, some researchers have turned to carbon nanotubes because they are stretchable, conductive, and appear transparent in thin layers, letting light shine through. However, for carbon nanotubes to hold their shape, they must be attached to some surface. Coating carbon nanotubes onto a plastic backing has not worked well, because the nanotubes slide off or past each other instead of stretching with the plastic. While some researchers have gotten around this problem, they still were not able to make a completely stretchable OLED.
To make their device entirely pliable, the UCLA researchers devised a novel way of creating a carbon nanotube and polymer electrode and layering it onto a stretchable, light-emitting plastic. To make the blended electrode, the team coated carbon nanotubes onto a glass backing and added a liquid polymer that becomes solid yet stretchable when exposed to ultraviolet light. The polymer diffuses throughout the carbon nanotube network and dries to a flexible plastic that completely surrounds the network rather than just resting alongside it. Peeling the polymer-and-carbon-nanotube mix off of the glass yields a smooth, stretchable, transparent electrode.

"The infusion of the polymer into the carbon nanotube coatings preserved the original network and its high conductance," saysQibing Pei, professor of materials science and engineering and principal investigator of the project.
"The approach we used is very simple and can be easily scaled up for real production," says Zhibin Yu, previously a researcher in Pei's group and now a researcher at University of California, Berkeley, and first author of the work, which was published online last month in Advanced Materials.

To create the stretchable display, the team sandwiched two layers of the carbon nanotube electrode around a plastic that emits light when a current runs through it. The team used an office laminating device to press the final, layered device together tightly, pushing out any air bubbles and ensuring that the circuit would be complete when electricity was applied. The resulting device can be stretched by as much as 45 percent while emitting a colored light

Where Is the Facebook for Old People?



Social networking is for the young, says a new survey
CHRISTOPHER MIMS


Pew just released a study whose takeaway is that for the first time ever, half of all Americans report being on a social network, such as Facebook, Myspace, Linkedin or Twitter. (The survey didn't mention Google+ or any others.)
But almost a third of Americans don't access the Internet at all, ever, so in some sense, the proportion who are accessing social networks is only relevant compared to how many are accessing the web in the first place. And here's where it gets interesting: One in three internet users -- tens of millions of Americans -- use the web without updating their status or checking out friends' endless barrage of baby pictures.
Who are these Internet-savvy people who have entirely dodged the personality-transforming phenomenon that is Facebook? For the most part, they're older. While 83 per cent of 18-29 year-olds use social networks (the figure is 89 per cent for women in that bracket), only half of those 50-64 use social networks. (And what portion of those users was dragged onto them just so they could keep tabs on the young people?)

This suggests a business opportunity.
Where is the online social networking equivalent of the Jitterbug phone? Easy to use, foolproof, and designed, more than anything, to keep you connected to loved ones. That could be the problem with social networks in the first place: they reward display and narcissism, exactly the traits most closely associated with youth. Apparently, genuine connection will have to wait for a more advanced technology.

An RNA Switch for Stem Cells



Missing link: Large RNA molecules called lincRNAs turn out to have an important role in controlling the function and fate of embryonic stem cells, like those pictured here.

BIOMEDICINE

An RNA Switch for Stem Cells

A new study reveals the influence of large RNA molecules in controlling stem cells.
  • BY COURTNEY HUMPHRIES
RNA molecules have long been known for their role in translating genes to proteins inside a cell, but more recently, scientists have found large numbers of RNA molecules that don't code for proteins but seem to have other cellular roles. Most research in mammals has focused on tiny RNA molecules called microRNAs, but a new study, published this week inNature, describes the far-reaching effects of much larger and relatively unstudied RNA molecules called lincRNAs (short for large intergenic noncoding RNAs). The study identifies lincRNAs that play a role in the function of embryonic stem cells, and suggests trying to use lincRNAs to manipulate these cells to spawn other cell types.
Mitchell Guttman, first author of the study and a graduate student at MIT and the Broad Institute, says that when the Broad team discovered more than 3,500 unique lincRNAs in the human and mouse genomes in 2009, "the potential was enormous, and we wanted to know what they could be doing."
To answer that question, the researchers focused on understanding lincRNAs' role in embryonic stem cells. Using a technique called RNA interference, they systematically shut down the function of each of more than 200 lincRNAs previously identified as playing a role in embryonic stem cells. They then profiled the genes expressed in the cells and studied their functions. They found that most lincRNAs have widespread effects on cells, and that they help control the fate of stem cells. The team identified about two dozen lincRNAs that help maintain the cell's pluripotency—its ability to beget all other kinds of cells—and a similar number of lincRNAs that repress genes involved in differentiating into other cell types.
Nudging stem cells to differentiate has proved challenging so far, and scientists have been looking for better ways. Guttman says that inhibiting lincRNAs in specific combinations may make it possible to direct stem cells to transform in specific ways. George Daley, a stem-cell biologist at Harvard Medical School and Children's Hospital Boston, says that further probing the effects of lincRNAs "will help refine our capacity to control and manipulate cells in culture, and this will advance the utility of stem cells for regenerative medicine."

Tariq Rana, an RNA biologist at Sanford-Burnham Medical Research Institute in La Jolla, California, calls the work "the first comprehensive study defining the functional roles of lincRNAs in embryonic stem cells." He says it will launch new investigations into how lincRNAs regulate gene expression.
Guttman and colleagues propose that lincRNAs have an important coordinating function in the cell: like sergeants commanding military units, single lincRNAs seem to interact with and control large complexes of proteins. He says that these large RNAs also seem to be put together in a modular way, like molecular Tinkertoys. Learning how they're put together could allow scientists to design and assemble RNAs to perform very specific tasks—and manipulate cells. 

GPS App Keeps Drivers' Eyes on the Road



An Android app navigates via camera images of the actual road—and any obstacles that might be there at the moment.BY IAN E. MULLER
Many drivers use GPS to find their way, but shifting their attention to the maps on the device can distract them from actual driving. A new app, Wikitude Drive, aims to help drivers navigate without diverting their attention away from the road. Philipp Breuss-Schneeweis, founder of Mobilizy GmbH, the Austrian company that developed the app, claims that "seeing the cars in front of you in the camera image can help you to avoid a crash. Many accidents actually happen when drivers look at the navigation system and the car ahead stops."
Wikitude Drive works by using an Android tablet or smart phone's camera to capture the roadway in front of the driver. The app then pulls information from a wide variety of sites, including Wikipedia, Yelp, Last.fm, Foursquare, and other online databases, to collect points of interest for the user, such as local businesses and concert locations. It uses the GPS and digital compass built into many phones and tablets to mark these sites directly on a live feed displayed on the device's screen—a technique known as augmented reality.
Wikitude Drive has only been officially supported on a handful of phones, but in practice it works on most Android devices.
Breuss-Schneeweis says that he's long wanted to use augmented reality for navigation. "The idea was to draw the driving instructions directly onto reality rather than an abstract map," he says. The company began developing the app in 2009, and released it in Europe in December of last year. Along the way, Breuss-Schneeweis says, the developers had to ensure that the app uses GPS sensors accurately, matching driving directions to streets exactly. They also had to make the app work consistently despite a flurry of changes to the Android operating system and the wide variety of devices that use it.

Wikitude Drive's developers hope this approach will keep users more focused on the road. As pointed out on the Wikitude Drivesite, when a driver takes his or her eyes off the road for one second to look at a map screen when driving at 100 kilometers (60 miles) per hour, "the driver is actually 'blind' for 28 meters (92 feet)."
However, Paul Green, a research professor at University of Michigan's Transportation Research Institute, is skeptical as to whether the app is addressing the biggest safety concerns. The main source of driver distraction for GPS devices and apps, he says, comes when the user programs a destination. Green believes the best way to improve GPS driving safety would be to "lock out destination entry while the [navigational] system is in use."
Green does say that the app could help solve very specific driving concerns, such as confusion while performing complex navigation maneuvers, or navigating through turns in an area with many roadways.
