Departing Secretary of State Clinton's Legacy of Firsts













After 31 years of public service, Secretary of State Hillary Clinton leaves the limelight behind.


On Friday, President Obama nominated Sen. John Kerry, D-Mass., to take her place as secretary of state, leaving Clinton to help him move in and then bow out.


Over the past three decades, Clinton has served her country in one way or another, a tenure that was full of firsts.


She was the only first lady to refuse the traditional cookie bake off and the first secretary of state to visit more than 100 countries. She served under the first black president and was the first first lady to have an office in the West Wing of the White House. Clinton was the first secretary of state to visit East Timor, and the first first lady to later win elective office. And long before she ever appeared on a ballot, Clinton was the first child born to Hugh and Dorothy Rodham.


Hillary Clinton Through the Years


Her departure from the State Department does not come as a surprise. For the past year, she has made clear her intentions to step down and said her goodbyes at outposts all over the world.


"It's important for me to step off this incredibly high wire I've been on," Clinton said after casting her ballot in November's presidential election, "to take stock of the rest of my life."

Recently, she told ABC's Barbara Walters she's looking forward to taking a step back, "maybe do some reading and writing and speaking and teaching."


In October, she took the blame for State Department security failures that led to the death of four Americans, including Ambassador Christopher Stevens, in Benghazi, Libya. It was a move that signaled a willingness to put politics aside and embrace responsibility.


I take responsibility," Clinton said a month after the attack in an interview in Lima, Peru. "I'm in charge of the State Department's 60,000-plus people all over the world, 275 posts.


"The president and the vice president wouldn't be knowledgeable about specific decisions that are made by security professionals," Clinton said, a clear attempt to absolve a president who was up for re-election of blame with little regard for her own popularity.


At the end of November, Clinton reflected on her accomplishments as secretary of state over the past four years in two wide-ranging speeches on foreign policy.


Her four years of work focused on advancing rights for women and religious minorities across the globe, helping to maintain the tenuous peace between Israelis and Palestinians, discouraging Iran from obtaining nuclear weapons and, in her own words, "advancing a new approach to development that puts human dignity and self-sufficiency at the heart of our efforts."


Clinton reflected on her travels to more than 112 countries, calling it "shoe-leather diplomacy," and emphasizing the importance of being on the ground.


"I have found it highly ironic that, in today's world, when we can be anywhere virtually, more than ever people want us to show up, actually," she said at the Newseum in Washington, D.C. "Somebody said to me the other day, 'I look at your travel schedule.  Why Togo?  Why the Cook Islands?'  No secretary of state had ever been to Togo before.  Togo happens to be on the U.N. Security Council.  Going there, making the personal investment, has a real strategic purpose."


Though Clinton took political heat this year for her role in the Benghazi attack, her global colleagues joked and prodded her about a second presidential run at each increment of her long-term farewell. The popular Democrat continues to deny she'll run.

Rent in Orchard Rd prime areas down 0.28% in Q4






SINGAPORE: Prime area rent for shopping malls and retailers in Orchard Road inched down 0.28 per cent this quarter, compared to the previous quarter.

In a report by Savills World Research, average monthly rent in prime areas in Orchard Road were S$35.1 per square foot in the fourth quarter.

This is a slight drop from the S$35.2 per square foot in Q3.

Analysts felt that this is due to adjustments in the market, as rent in the area were growing too fast previously.

Alan Cheong, director of Savills Research said the fall could be due to over-expecting the level of tourism in Singapore.

He said: "While (tourism) did increase, apparently the spending power did not quite live up to its expectation. Rent and performance in the Orchard Road belt will be dependent on tourism trade and on the state of the economy."

More retail spaces will also be available soon.

Recently, Plaza Singapura completed its expansion works, providing 80 more shops.

A larger scale development, Orchard Gateway, will provide 180,000 square feet of retail space next year.

Analysts also say that a gloomy economic outlook ahead could also see rent fall by up to 3 per cent, and if economic growth slows, people will spend less.

Retailers may then take a hit, in turn exerting a downward pressure on rent.

Browsers: Top 5 events from 2012




For a while there, the browser was winning the war.


New startups launched online services rather than packaged software. Browser makers raced to transform the Web from a place to publish documents into a general-purpose programming platform. People spent more and more time using the Web instead of software that ran natively on devices.


Then the era of modern smartphones and
tablets began. And in 2012, it became clear that Web app advocates will have to work a lot harder to build a universal software foundation. Here's a look at what happened this year in the world of the Web, starting with an an extremely public vote of no confidence.

Facebook slaps down HTML5
The basic technology for describing Web pages is Hypertext Markup Language, and the new HTML5 version now symbolizes modern Web development, even though it also relies on other standards such as JavaScript for running actual programs and CSS for formatting and effects.


The HTML5 idea is that Web apps can span many devices -- Windows machines, Macs, smartphones, tablets, and more -- because everything has a browser these days. One of the biggest advocates of the approach was Facebook, which used Web coding to reach a tremendous range of devices.


But Facebook this year abruptly changed course, choosing instead to release native iOS and
Android apps. The company had loved the Web approach, which let its programmers constantly release new versions that would load the same way a browser loads a fresh version of a Web site. But the performance wasn't acceptable.


"I think the biggest mistake that we made as a company is betting too much on HTML5 as opposed to native," Chief Executive Mark Zuckerberg said. "Probably we will look back saying that is one of the biggest mistakes if not the biggest strategic mistake that we made."


Zuckerberg's long-term enthusiasm for Web apps was a pretty unappealing consolation prize.



Facebook founder and CEO Mark Zuckerberg called his company's reliance on Web apps for mobile access to the site a major strategic error.

Microsoft stiffs browser rivals
With
Windows 8, Microsoft is trying to make a fresh start with the operating system interfaces that software can use. Windows 8 marries the older Win32 interfaces with the new WinRT. But Windows RT, the cousin that runs on mobile devices such as Microsoft's Surface that use ARM processors, lets third-party software use only the WinRT interfaces.


That happens to hobble browsers -- well, third-party browsers like Chrome and Firefox. Microsoft's own IE10 gets access to the low-level Win32 interfaces, letting it run JavaScript faster. Mozilla objected strenuously, and Google piled on, too. Microsoft carved an exception for browsers running on Windows 8, no doubt encouraged by its earlier antitrust woes involving Internet Explorer, but the company doesn't look likely to budge on Windows RT.


Even though European officials are checking into the situation, legal experts think any opponents would have a hard antitrust case.


The result, though could be that browser choice becomes a thing of the past. Safari dominates on iOS, Android's browser on Android, and IE on Windows Phone. Even if people might want a choice, company limits often preclude it.

Do Not Track derailed
Microsoft also threw a wrench in the works of a proposed new standard called Do Not Track (DNT) that's designed to let people tell Web sites not to keep tabs on their online behavior. The effort grew out of a Federal Trade Commission request for the industry to come up with a voluntary solution to the issue, since privacy advocates are not happy with the idea of behavioral targeting of advertisements.


Mozilla proposed a solution that got traction in Chrome, Opera, and Safari, in which browsers would tell Web sites not to track if people had expressly set the browser to send the message. But Microsoft, saying it wanted more privacy, turns DNT on if people accept the Windows 8 default installation settings. That might sound great for privacy, but online advertisers say they'll ignore the setting if it hasn't been expressly set by users.


DNT author Roy Fielding, an Adobe scientist and programmer in the Apache Web server software project, one-upped Microsoft by patching Apache so it overrides IE's DNT setting. But Microsoft isn't budging.


What could break the DNT gridlock? Perhaps the appointment of Peter Swire as co-chair of the group trying to standardize it.


Microsoft's IE has stopped its market-share losses, with Chrome and Firefox jockeying for second place.

IE gets real
There's a big community of people who don't like Microsoft's browser actions -- squashing Netscape in the 1990s then letting IE6 lie fallow for years.


But that's old thinking. Microsoft dragged itself back aboard the Web standards bandwagon with IE9. But this year's release of IE10 -- packaged with Windows 8 and set to arrive in finished form later for Windows 7 -- that's the stronger statement.


IE10 supports a long list of new Web standards: IndexedDB and AppCache for writing Web apps that work even when a computer doesn't have a Net connection; support for a range of pointers including multitouch interfaces; asychronous script execution for getting Web pages to load faster and run more smoothly; the file interface for better uploads and ways for apps to access data; sandbox security restrictions; and a lot of Cascading Style Sheets (CSS) effects.


And it's pretty fast to load Web pages. All this means IE10 can compete -- and not just because it's built into Windows. There are still some missing features -- the WebGL interface for 3D graphics, for instance, which Microsoft thinks is a security risk -- but even without it and some other omissions, Web programmers still can look forward to IE's transition to a modern browser.


Naturally, Microsoft is tooting its IE horn as a result. And it has a strong incentive to keep pushing ahead: Windows 8 apps can be written using the JavaScript, CSS, and HTML Web technologies. Microsoft might have a vanishingly small share of Web usage in the mobile market, but it has mostly stopped IE's share losses in PC browser usage.

Price cut makes Chromebooks worthwhile
Chrome OS, Google's browser-based operating system, was a wacky idea when it debuted in 2009 and still not very compelling when it arrived in products called Chromebooks in 2011. But in 2012, Google and its Chrome OS allies came up with a much more compelling recipe by lowering the price.


First came the $249 Samsung Chromebook, which uses an ARM processor rather than a more conventional Intel chip. Next was the even cheaper Acer C7 Chromebook, which uses an Intel chip but drops the SSD in favor of a conventional hard drive.


Neither can come anywhere close to replacing a video-game rig or Photoshop workstation. But for the price, they can be a capable second or third machine to have around the house for e-mail, surfing, Facebook, and homework assignments. They may not have the entertainment appeal of a tablet packed with games, but they're cheaper than a new iPad, and a lot of people prefer a keyboard when it's time to type.


Samsung also released some higher-end Chromebooks and the first Chromebox, a small machine that requires an external monitor, keyboard, and mouse. They're more expensive, but in combination with the significantly revamped Chrome OS and integrated with Google Drive, they're useful for a certain population.


Web apps may be struggling on smartphones and tablets, but for a laptop, they're a more realistic option. Browser makers and Web developers have work to do on mobile, but they're hardly an endangered species.

Pictures: Fungi Get Into the Holiday Spirit


Photograph courtesy Stephanie Mounaud, J. Craig Venter Institute

Mounaud combined different fungi to create a Santa hat and spell out a holiday message.

Different fungal grow at different rates, so Mounaud's artwork rarely lasts for long. There's only a short window of time when they actually look like what they're suppose to.

"You do have to keep that in perspective when you're making these creations," she said.

For example, the A. flavus fungi that she used to write this message from Santa grows very quickly. "The next day, after looking at this plate, it didn't say 'Ho Ho Ho.' It said 'blah blah blah,'" Mounaud said.

The message also eventually turned green, which was the color she was initially after. "It was a really nice green, which is what I was hoping for. But yellow will do," she said.

The hat was particularly challenging. The fungus used to create it "was troubling because at different temperatures it grows differently. The pigment in this one forms at room temperature but this type of growth needed higher temperatures," Mounaud said.

Not all fungus will grow nicely together. For example, in the hat, "N. fischeri [the brim and ball] did not want to play nice with the P. marneffei [red part of hat] ... so they remained slightly separated."

'Cliff' Deniers Put Faith in No Deal













Not everyone thinks the "fiscal cliff" is so bad.


If the Dec. 31 deadline passes, income taxes will go up and across-the-board spending cuts will hit government programs. But while most of the political world frets as if a major disaster is looming, others have treated it more like the Y2K bug: a fiscal canard ginning up a lot of unnecessary panic.


The cliff is a "fantasy," former House speaker Newt Gingrich told a sold-out crowd at the Ronald Reagan library in Simi Valley, Calif., a week before Election Day.


"It is an excuse to panic," Gingrich said. "It is a device to get all of us running down the road so we accept whatever Obama wants, because otherwise we will have failed the fiscal cliff, and how can you be a patriot if you don't do what the fiscal cliff requires?"



Fiscal Cliff 'Plan B' Is Dead: Now What?


The former speaker wanted Republicans to stop negotiating with President Obama, for fear of giving too much away. "Back out of all of this negotiating with Obama," Gingrich publicly advised House Republicans. "The president is overwhelmingly dominant in the news media" but, at the opposite end of the political spectrum, liberals have said the same thing for a similar reason.

'Fiscal Cliff' Negotiations: Boehner's Plan B Watch Video







While the "cliff" would mean higher taxes on the middle class, it would also mean higher taxes on the wealthy, a chief demand for liberals. Automatic budget cuts would hit defense programs, which liberals have wanted to cut anyway, but not the Medicare and Social Security entitlements that Democrats and progressives want so badly to protect.


Boehner Pulls 'Plan B' Amid GOP Disarray


Van Jones, the environmental activist and resigned White House green jobs "czar," sought to quiet the "fiscal cliff" alarms Election Night on CNN. "The problem with the label 'the cliff' is that it creates a mindset that there is nothing worse that this set of cuts, and there are things that are worse," Jones said.


"We cannot be in a situation where we get bullied or stampeded into putting in a deal that's even worse than what the fiscal cliff is about."


Jones later wrote on his blog that the "fiscal cliff" is actually a "fiscal bluff": "The so-called fiscal cliff is actually a fiscal bluff --- a made-up crisis to make us think our government is out of money and time. Congress continues to drag its feet over raising taxes on the wealthiest Americans, despite the top 1% earning 23% of the nation's income, and insists on calling for cuts to vital programs instead of reining in massive subsidies ($100 billion in 2011 alone) to major corporations that already make billions in profits.


"America isn't broke --- it's being robbed.
Gingrich and Jones started the conversation, but as the deadline creeps closer, others are finishing it."


To some, the "fiscal cliff" offers a clearer upside.


"Democratic and progressive leverage goes immensely up if we get past the beginning of the year," Adam Green of the Progressive Change Campaign Committee told ABC News. "Once they have to proactively lower taxes on the rich, it makes it harder and harder to move that number up and makes it easier and easier to force votes or demand votes on policies that clearly benefit the middle class."


Green says liberals will get what they want immediately, if the Dec. 31 deadline passes without a deal.


"We really want to get past the first of the year so that we have that leverage in the bag," Green told ABC. "It will also show that the fiscal cliff was a mess. If we get into 2013, the really good stuff happens right away, and the really big cuts are a 10-year phasing."

Avian flu virus learns to fly without wings









































Potentially fatal bird flu viruses can spread on the wind, a hitherto suspected but unproven route of transmission.











Usually, people catch bird flu through close physical contact with each other or, much more commonly, with infected poultry.













The newly identified capacity for wind to spread it opens up a potential route by which the viruses can spread between farms.












The finding came about after Dutch researchers studied an outbreak of the avian flu strain H7N7 in poultry on Dutch farms in 2003, which resulted in 89 confirmed human infections including one death.












Computer models showed that wind patterns at the time of the outbreak explain how different genetic variants of H7N7 ended up on different farms (Journal of Infectious Diseases, doi.org/j3b).












H5N1 is the most harmful strain of avian flu, having killed 360 of 610 infected people since it was discovered in 2003. The fact that a related strain can travel on the wind suggests that H5N1 can too, says Marion Koopmans of the Dutch National Institute for Public Health and the Environment in Bilthoven, who coordinated the research project. "You must assume that this same potential is there for H5N1," she says.












Other researchers agreed that by implication, H5N1 could spread in the same way. "Because we don't know, we should assume the worst case – and the worst case is that H5N1 travels on the wind as well," says John McCauley, a bird flu researcher at the MRC National Institute for Medical Research in London.












He says it's well known that the virus that causes foot and mouth disease in cattle and pigs travels many kilometres on the wind, but it's lighter than avian flu and is produced in huge amounts by infected animals. McCauley says the most likely scenario for bird flu is that the virus hitches a ride on airborne particles from farms, especially particles of infected faeces from poultry farms.

ASEAN will continue to push for open skies agreement with India: PM Lee






SINGAPORE: Prime Minister Lee Hsien Loong said the issue of an open skies agreement between ASEAN and India is something which Singapore will continue to push for.

Speaking to the Singapore media at the end of his visit to New Delhi for the ASEAN-India commemorative summit, Mr Lee said passenger traffic keeps on growing, and hence the need for more capacity.

"I keep on making the point to them that if you want to engage Asia, if you want to engage ASEAN, this is really one of the easiest ways you can help to make it happen because if you open up the links, then the businessmen will travel, the tourists will travel, the business opportunities will be identified, more investments will come.

"I think the business people are quite persuaded but I think it's a subject we need to keep on pushing because some of the incumbent players, they prefer a slower pace. I hope there will be progress. The Singapore-India path we are discussing how to improve the air services agreement. The ASEAN-India air services agreement is something they have not started talking about, but we hope that they will begin soon," he shared.

Mr Lee concluded his trip to New Delhi with a visit to the Red Fort and he had the opportunity to meet the Singaporean team which took part in the ASEAN-India Car Rally.

The Prime Minister was encouraged by their participation, and it was also an opportunity for him to hear first-hand their experiences in driving 8,000 kilometres and through several states in ASEAN, before reaching New Delhi.

iOS 6.0.2 triggering battery drain, say some users



The famed iPhone battery drain issue seems have to resurfaced for some people who've made the leap to
iOS 6.0.2.


Several users chiming in on Apple's Discussion Forums say the latest iOS update, which was designed to fix Wi-Fi problems, is draining their batteries faster.


One iOS 6.0.2 updater said that "I can usually get through a day with about 75 percent of my battery power remaining. Today I've gone through 90 percent and I've done nothing special with it."


Another said: "Today I barely used my phone at all, and I noticed I was down to 40 percent after 3 hours of being off the charger. This is a significant change in battery drain."


A third commented that "before with the 6.0.1 I didn't have any kind of problem with the battery, I could have my battery full charged without doing any use of the
iPhone 5 the whole night keeping 100 percent. But this morning when I woke up the battery was in 91 percent obviously without using the iPhone during the night."


Similar complaints have been shared with blog site MacNN, which pointed to Apple news site TidBITS for a theory behind the reported battery drain.


TidBITS authors Adam Engst and Michael Cohen speculate that the problem may be triggered by a change in the Wi-Fi behavior in iOS 6.0.2. Specifically, the new OS seems to have increased the number of Wi-Fi checks it performs in order to resolve the previous wireless connection issues, according to MacNN.


Reports of increased battery drain seem to be a common complaint each time a new version of iOS is released. But as usual, the problem this time is far from universal.


Some people commenting on the TidBITS story say they do find their battery draining faster, but others say they've seen no problem at all. The iOS 6.0.2 update was rolled out only to the iPhone 5 and
iPad Mini, which also limits the number of users potentially affected.

CNET contacted Apple for comment and will update the story if the company responds.

Hollies Get Prickly for a Reason



With shiny evergreen leaves and bright red berries, holly trees are a naturally festive decoration seen throughout the Christmas season.


They're famously sharp. But not all holly leaves are prickly, even on the same tree. And scientists now think they know how the plants are able to make sharper leaves, seemingly at will. (Watch a video about how Christmas trees are made.)


A new study published in the Botanical Journal of the Linnean Society suggests leaf variations on a single tree are the combined result of animals browsing on them and the trees' swift molecular response to that sort of environmental pressure.


Carlos Herrera of the National Research Council of Spain led the study in southeastern Spain. He and his team investigated the European holly tree, Ilex aquifolium. Hollies, like other plants, can make different types of leaves at the same time. This is called heterophylly. Out of the 40 holly trees they studied, 39 trees displayed different kinds of leaves, both prickly and smooth.

Some trees looked like they had been browsed upon by wild goats and deer. On those trees, the lower 8 feet (2.5 meters) had more prickly leaves, while higher up the leaves tended to be smooth. Scientists wanted to figure out how the holly trees could make the change in leaf shape so quickly.


All of the leaves on a tree are genetic twins and share exactly the same DNA sequence. By looking in the DNA for traces of a chemical process called methylation, which modifies DNA but doesn't alter the organism's genetic sequence, the team could determine whether leaf variation was a response to environmental or genetic changes. They found a relationship between recent browsing by animals, the growth of prickly leaves, and methylation.


"In holly, what we found is that the DNA of prickly leaves was significantly less methylated than prickless leaves, and from this we inferred that methylation changes are ultimately responsible for leaf shape changes," Herrera said. "The novelty of our study is that we show that these well-known changes in leaf type are associated with differences in DNA methylation patterns, that is, epigenetic changes that do not depend on variation in the sequence of DNA."


"Heterophylly is an obvious feature of a well-known species, and this has been ascribed to browsing. However, until now, no one has been able to come up with a mechanism for how this occurs," said Mike Fay, chief editor of the Botanical Journal of the Linnean Society and head of genetics at the Kew Royal Botanic Gardens. "With this new study, we are now one major step forward towards understanding how."


Epigenetic changes take place independently of variation in the genetic DNA sequence. (Read more about epigenetics in National Geographic magazine's "A Thing or Two About Twins.")


"This has clear and important implications for plant conservation," Herrera said. In natural populations that have their genetic variation depleted by habitat loss, the ability to respond quickly, without waiting for slower DNA changes, could help organisms survive accelerated environmental change. The plants' adaptability, he says, is an "optimistic note" amidst so many conservation concerns. (Related: "Wild Holly, Mistletoe, Spread With Warmer Winters.")
