2013 Smart Guide: Searching for human origins in Asia

Read more: "2013 Smart Guide: 10 ideas that will shape the year"

Move over Africa. It is where humanity began, where we took our first steps and grew big brains. But those interested in the latest cool stuff on the origins of our species should look to Asia instead.

Why so? It looks as if some early chapters in the human story, and significant chunks of its later ones too, took place under Asian skies.

For starters, 37-million-year-old fossils from Burma are the best evidence yet that our branch of the primate tree originated in Asia rather than Africa.

A great deal later, after the emergence of early humans from Africa, some of our distant cousins set up shop in Asia, only to die out later. In 2012 anthropologists described for the first time human fossils unlike any others - ancient hominins dubbed the Red Deer Cave People who lived in what is now China as recently as 15,000 years ago, then vanished without further trace.

The implication is that more long-lost cousins remain to be found in South-East Asia's neglected fossil record. We know a little about the enigmatic Denisovans, for example. Their DNA was first discovered in 50,000-year-old fossil fragments from a Siberian cave in 2010, and traces of that DNA live on in modern Indonesians. Not only does this show that the Denisovans interbred with our species, it also suggests they occupied a territory so large it took in South-East Asia as well as Siberia.

Yet the only evidence we have of their existence are a finger bone and a tooth. Too long have the vast plains and forests of Asia remained untouched by the trowels and brushes of palaeoanthropologists. Teams of them are champing at the bit to explore Asia's rocks. Denisovans - and, hopefully, other ancestors, too - will not remain faceless for long.

Kingfisher shares rise on new licence application

NEW DELHI: Shares in India's grounded Kingfisher Airlines climbed nearly three per cent on Friday on news that the stricken carrier has applied to renew its operating licence.

The move came days after Kingfisher, whose liquor baron owner Vijay Mallya has been desperately seeking investment from foreign carriers, said it aims to resume operations in a "phased manner".

Kingfisher's shares rose to 15.88 rupees in morning trade after regulatory authorities confirmed it had applied Thursday for the licence renewal.

An official said, however, that the application had not included the revival plan that has been demanded by regulators.

"This application needs to be made as their licence is expiring but there can be no (licence) renewal without a revival plan," the official at the Directorate General of Civil Aviation told AFP, asking not to be named.

Kingfisher, once India's second-largest airline by market share, could not be immediately reached for comment but it said on Monday it has come up with a full recapitalisation plan.

The firm has not flown since its planes were grounded in October by an employees' strike over unpaid wages, leading the regulator to suspend its operating licence until it comes up with a "viable" revival formula.

The airline, whose current licence expires on December 31, said last week it was in talks with investors including Abu Dhabi-based Etihad Airways.

But aviation analysts have expressed doubt whether Etihad would be interested in Bangalore-based Kingfisher given its debt load, which is estimated at $2.5 billion by the consultancy firm Centre for Asia Pacific Aviation.

Kingfisher's shares have climbed from an all-time low of 7.05 rupees in August on investor hopes a stake sale will avert a shutdown but they are still trading at a fraction of their record 2007 peak of 334 rupees.

Web media: The 5 biggest stories of 2012

Kim DotCom's arrest and subsequent legal fight was one of the biggest stories in digital media during the past year. Check out the rest of them.

Fun, fun, fun!

That's what digital movies, music, and books are supposed to be about. But for the people who create and sell the stuff, it's been all crumbs, crumbs, crumbs.

The past year was another tough one for the sale of entertainment media on the Web. The irony is that as more entertainment fare is sold online, the less profitable the businesses become.

Few, if any, online music services are profitable. In Web movie distribution, download sales are dismal. Even Netflix, the Web's top video rental service, saw a slow down in the rate it added subscribers. But the sector also saw some triumphs. Here's our list of the most important stories of 2012.

1. The MegaUpload bust

The biggest story in online entertainment this year began with the thumping sound of helicopter blades beating the air. In January, choppers carried New Zealand police, armed with semi-automatic weapons, to the grounds of the mansion leased by MegaUpload founder Kim DotCom. He and other members of the company's management were arrested.

In an indictment, the United States Attorney accused the group of encouraging people across the globe to store pirated media in MegaUpload's digital lockers. This allowed managers to generate more than $175 million from the sale of ads and subscriptions. The defendants were charged with criminal copyright infringement.

The amount of force used in the police raid stunned the tech world. Typically copyright disputes are settled in civil court -- not at the point of a gun. The bust quickly prompted some of MegaUpload's competitors to shut their doors. DotCom and the other defendants say they're innocent and are fighting U.S. attempts to extradite them.

2. Netflix struggles to win back customers' faith

For most of this year, Netflix trudged down the same rocky path it ended 2011 on. CEO Reed Hastings was once a Silicon Valley star, but last year investors and customers lost confidence in his leadership when he botched a price increase and then stoked the anger of already bitter customers by trying to spin off the company's DVD operations. This year, Netflix fell short of projections for adding new customers and was again criticized for offering a stale streaming library. Customers asked where all the newer titles were.

In addition, some of what were likely embarrassing details about Hastings' past goofs, such as how he alienated some top lieutenants and his fib about where the idea for Netflix came from, were revealed in a CNET story as well as in "Netflixed," a book by author Gina Keating. But Hastings and company may finally be ready to break out of their slump.

Earlier this month, Netflix stunned the digital entertainment world by signing an exclusive deal with Disney to distribute the studio's new movie releases right after they're made available for sale on DVD and by download. This distribution window is typically reserved for pay-TV channels. Netflix climbed into that window and became the first Web subscription service ever to deliver films during the period.

3. Apple, book publishers accused of fixing e-book prices

Apple and five of the country's largest book publishers conspired to fix e-book prices and in the process betrayed consumers, according to a complaint filed in April by the U.S. Department of Justice. The DOJ accused Apple of convincing Hachette, Macmillan, Penguin, Simon & Schuster, and HarperCollins to swap the industry's decades-old business model for one that would enable them, instead of retailers, to control e-book prices. The DOJ contends that the plot was hatched to hobble Amazon, which had discounted prices heavily and owned about 90 percent market share.

The accused publishers raised prices nearly in unison and that was just one of the reasons the government's case appeared strong from the beginning. Then, HarperCollins, Hachette, and Simon & Schuster (owned by CBS, parent company of CNET) quickly settled. Those three publishers agreed to give back control of pricing to retailers and pledged not to share information with each other. They also stopped guaranteeing that Apple would offer the lowest prices available online. Apple, Penguin, and Macmillan deny wrongdoing and are fighting the DOJ in court.

4. Entertainment sector's antipiracy effort suffers blow when SOPA gets crushed

In 2011, the entertainment sector labored to win support in Congress for legislation known as the Stop Online Piracy Act (SOPA). Backers said the bill would give law enforcement officials a freer hand in shutting down accused pirate sites. In January 2012, the tech sector rose up and easily snuffed out any chance of the bill passing.

Some of the most trafficked Internet sites, such as Google and Wikipedia, helped generate opposition to SOPA by urging users to request that their representatives on Capitol Hill vote no. Not only did many former Congressional supporters reverse course but President Barack Obama also distanced himself from SOPA.

At one time, the trade groups of the big music labels and film studios cast big shadows in Washington. The SOPA defeat, however, was a sign that the tech sector has begun to eclipse them. The talk coming from the big media companies now is about building consensus with tech companies on piracy issues. SOPA is dead.

5. Aereo challenges big TV

Tick off the different major media categories -- newspapers, video games, music, movies, books, radio, and TV -- and they're all online save one.

Live television is the last holdout, and the companies with huge investments in live TV are trying to keep it that way. In a story that's been under-reported, New York-based Aereo is being sued for distributing live, over-the-air broadcast signals to subscribers via the Internet. ABC, CBS, NBC, PBS, and Fox have filed lawsuits and accuse Aereo of violating their copyrights and owing them retransmission fees.

Aereo, backed by former television executive Barry Diller, says it doesn't owe a cent because it doesn't retransmit. The signals that Aereo provides come from dime-size antennas that the company's customers control with help from the Web. It is they who are capturing the signals and Aereo argues that they have every right to access the freely available broadcasts. Aereo prevailed in district court against an attempt to shut the service down earlier this year, but the broadcasters have appealed. Stay tuned.

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.")

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

Dec 20, 2012 11:00pm

The defeat of his Plan B — Republicans pulled it when it became clear it would be voted down — is a big defeat for Speaker of the House John Boehner.  It demonstrates definitively that there is no fiscal cliff deal that can pass the House on Republican votes alone.

Boehner could not even muster the votes to pass something that would only allow tax rates on those making more than $1 million to go up.

Boehner’s Plan B ran into opposition from conservative and tea party groups -including Heritage Action, Freedom Works and the Club for Growth – but it became impossible to pass it after Senate Democrats vowed not to take up the bill and the president threatened to veto it.  Conservative Republicans saw no reason to vote for a bill conservative activists opposed – especially if it had no hopes of going anywhere anyway.

Plan B is dead.

Now what?

House Republicans say it is now up to the Senate to act.  Senate Democrats say it is now up to Boehner to reach an agreement with President Obama.

Each side is saying the other must move.

The bottom line:  The only plausible solution is for President Obama and Speaker Boehner to do what they have failed repeatedly to do:  come up with a truly bi-partisan deal.

The prospects look grimmer than ever. It will be interesting to see if the markets react.

2013 Smart Guide: New maps to rein in cosmic inflation

Read more: "2013 Smart Guide: 10 ideas that will shape the year"

We're about to get a better grasp of one of the biggest ideas in the universe: inflation. The first maps of the cosmos from the European Space Agency's Planck satellite are due out in early 2013. They should help us to hone descriptions of how, after the big bang, the universe grew from smaller than a proton into a vast expanse in less than a trillionth of a trillionth of a second.

The early universe was a featureless soup of hot plasma that somehow grew into the dense galaxy clusters and cosmic voids we know today. On a large scale, regions far apart from each other should look very different, according to the laws of thermodynamics. But studies of the cosmic microwave background (CMB) - the first light to be released, some 300,000 years after the big bang - show that the universe still looks virtually the same in all directions.

To explain this unlikely sameness, physicists invoked inflation: since all points in the universe were once next-door neighbours, the idea is that they blew apart so quickly that they couldn't forget about each other. Data from NASA's Wilkinson Microwave Anisotropy Probe (WMAP), launched in 2001, bolstered a key prediction of inflation, that the universe's structure was seeded by quantum fluctuations in space-time.

Stephen Hawking recently told New Scientist that WMAP's evidence for inflation was the most exciting development in physics during his career. But a best-fit model for what drove the exponential expansion, when it began and how long it lasted, hasn't been agreed. The WMAP data also revealed some surprises, such as inexplicable patterns in the CMB. So cosmologists have been anxiously awaiting Planck's higher-resolution maps to set the record straight. The Planck team will release its first cosmological results from 15 months' worth of data in March.

In addition, the Planck results will help refine figures for how much dark energy, dark matter and normal matter make up the universe. Planck might also record the first direct signs of ripples in space-time called gravitational waves. Not bad for a probe that's already half dead - one of Planck's two detectors stopped working in January. The entire craft will be shuttered in August.

Facebook in 2012: 5 ways its IPO changed the social giant

Now that was a year Mark Zuckerberg will never forget -- even if he didn't celebrate each moment on Facebook, as he wants the rest of the world to do. Sure, he turned 28 and married longtime girlfriend, Priscilla Chan, in a backyard ceremony at the couple's home in Palo Alto, Calif. But that's the stuff of ordinary men. Make no mistake: 2012 will go down as the year in which Zuckerberg came out from under his hoodie and tried to prove himself as leader of one of the titans of consumer tech.

Is he succeeding? So far, sure, and more so as the year went on. While plenty of people like to complain about Facebook -- it's a time soak, a privacy nightmare -- plenty of others, as in hundreds of millions, clearly love it. Which is why Wall Street was in a tizzy when Facebook finally went public, an event that forever changed Facebook, making it far and away the most important development at Facebook this year.

1. Facebook's faceplant

Not since the Internet mania of the 1990s had we seen such hype and expectation over an IPO. And why not? This was Facebook, after all, a new kind of media company that had amassed hundreds of millions of passionate users and was already turning a profit on $4 billion in revenue by the time it filed to go public. This one was going to make armchair investors everywhere rich, and fast.

We all know what happened: The hype -- and the $100 billion-plus valuation Wall Street bankers awarded Facebook -- was all too much. Way too much. Sure, Facebook pulled off the biggest Internet IPO in history, which was great for Facebook, but then its shares began their speedy descent. Lawsuits were filed around the handling the IPO. Some even called for Zuckerberg's head, although Zuckerberg structured the company in way that makes firing him impossible. And the whole mess quashed hopes of a return to 1999-style Internet mania.

The upshot: Facebook's botched IPO sent fears across startup land and even now venture capitalists are cutting fewer checks to Zuckerberg wannabes since the possibility of a big IPO exit -- at least for consumer Internet companies -- is grim for now. (To be fair, IPO duds Groupon and Zynga also played a big role on this front). Despite all this, Facebook's stock, while still far from its IPO price of $38 a share, ended the year on a tear as Zuckerberg and team began to show they were serious about making money, especially from mobile.

2. Zuckerberg buys Instagram
Almost everything we hear about from Facebook these days has to do with mobile, and how the company has been restructured to emphasis "mobile first." And nothing shows just how concerned Zuckerberg was about the great mobile migration then when he singlehandedly struck a deal with Instagram cofounder Kevin Systrom to buy his two-year-old startup in a stock-and-cash deal worth $1 billion. Istagram had amassed 33 million users, and Zuckerberg knew that it was both a threat and the future. So he pounced -- just a month before Facebook's May IPO.

The critics pounced. Why spend $1 billion for a money losing startup without a business model? But Zuckerberg didn't care. And when Facebook amended its IPO filing with the SEC -- just over a week before the IPO -- to emphasize how the shift of its users to mobile devices was threatening its long-term ad revenue, it all all started to make sense. Zuckerberg needed more mobile juice, at any cost. By the time the Instagram deal finally closed in October, the price came in at $715 million due to Facebook's sagging stock. Instagram is still on fire. It reached 100 million users in September, and, by one account, people are spending more time on it than on Twitter.

Then -- and this arguably deserves its own entry among top stories for 2012 -- management blundered badly in mid-December when it unveiled Instagram's new terms of service, which said that the company could sell your photos or use them in advertisements. You have to wonder who signed off on this one. Unsurprisingly, the backlash was swift. Instagram co-founder and chief executive Kevin Systrom apologized, backpedaled and said the company is "working on updated language."

3. Speaking of a billion...
This was the year when, with great fanfare, Facebook crossed the billion member mark. No consumer Internet company -- heck, no company, period -- has ever done that. Not bad for what began as a side project in Zuckerberg's Harvard dorm room eight years earlier. It's worth pointing out that these are "monthly active users," measured as people who log on to Facebook at least once a month. Still, that's one seventh of the entire world population. And Facebook's daily active user number is hardly shabby. That metric averaged 584 million in September, a 28 percent jump from the period year. As for mobile? Monthly active mobile users soared 61 percent to 604 million.

Zuckerberg and his team aren't satisfied with one billion, of course. Around five billion people are expected to be online by the end of the decade -- largely via phones -- and Facebook wants all of them conducting their Internet lives through Facebook. Growth has slowed in the U.S, but the company has its sights on all pockets of the globe, as evidenced by its reworked instant messenger app released in early December.

4. I'm talking to you, Wall Street
The rap against Zuckerberg, at least from Wall Street, had been that he didn't care about the money side of the business. In September, he sat for his first live interview (at the TechCrunch Distrupt conference) since the IPO and worked hard to disabuse the world that notion, arguing that Facebook can be a great place for users and can make a ton of money. This will go down as the day Zuckberg took control of the narrative and his messaging to Wall Street. This was also when he began preaching that mobile wasn't a problem for Facebook, but an opportunity -- a talking point that clearly went out to all Facebook execs, who now love talking about mobile, mobile and more mobile.

Soon after that, Zuckerberg showed it was more than talk. Facebook started inserting ads -- called "Sponsored Stories" -- on its mobile apps in March, its first effort to make money from mobile. And the results started to show up this fall. When Facebook reported its third-quarter earnings, it said that mobile ads made up 14 percent of its total ad revenue -- largely putting to an end to the biggest worry among Wall Street since Facebook went public.

5. Buy your friend a drink
It's hard to pinpoint one money-making tactic that Facebook launched in 2012 as most important. The company did go all out in this regard. A few examples: It launched Facebook Exchange, an ad-bidding system that lets advertisers better target users on Facebook by tracking what else they do across the Web; it started letting users pay $7 to promote a post to ensure it'll land in a lot of News Feeds; it began charging business for Facebook Offers, a way for merchants to send Groupon-like deals to your News Feed.

But here's one that's unlike the others: The launch of Facebook Gifts, which lets you easily buy a Facebook friend a gift -- from an
iTunes gift card, to an item from Baby Gap or even a bottle of wine that gets shipped to your home. This is a huge move. It helps Facebook get credit card numbers on files -- important for future products -- and marks Facebook's march into commerce. Arguably, Facebook Gifts isn't yet about the money -- it's more about keeping people using Facebook -- but that'll change quickly.

And when that happens, that will certainly give Zuckerberg and his team something they can all drink to.

Detecting Rabid Bats Before They Bite

A picture is worth a thousand words—or in the case of bats, a rabies diagnosis. A new study reveals that rabid bats have cooler faces compared to uninfected colony-mates. And researchers are hopeful that thermal scans of bat faces could improve rabies surveillance in wild colonies, preventing outbreaks that introduce infections into other animals—including humans.

Bats are a major reservoir for the rabies virus, according to the Centers for Disease Control and Prevention (CDC) in Atlanta. Previous research shows that bats can transmit their strains to other animals, potentially putting people at risk. (Popular Videos: Bats share the screen with creepy co-stars.)

Rabies, typically transmitted in saliva, targets the brain and is almost always fatal in animals and people if left untreated. No current tests detect rabies in live animals—only brain tissue analysis is accurate.

Searching for a way to detect the virus in bats before the animals died, rabies specialist James Ellison and his colleagues at the CDC turned to a captive colony of big brown bats (Eptesicus fuscus). Previous studies had found temperature increases in the noses of rabid raccoons, so the team expected to see similar results with bats.

Researchers established normal temperature ranges for E. fuscus—the bat species most commonly sent for rabies testing—then injected 24 individuals with the virus. The 21-day study monitored facial temperatures with infrared cameras, and 13 of the 21 bats that developed rabies showed temperature drops of more than 4ºC.

"I was surprised to find the bats' faces were cooler because rabies causes inflammation—and that creates heat," said Ellison. "No one has done this before with bats," he added, and so researchers aren't sure what's causing the temperature changes they've discovered in the mammals. (Related: "Bats Have Superfast Muscles—A Mammal First.")

Although thermal scans didn't catch every instance of rabies in the colony, this method may be a way to detect the virus in bats before symptoms appear. The team plans to fine-tune their measurements of facial temperatures, and then Ellison hopes to try surveillance in the field.

This study was published online November 9 in Zoonoses and Public Health.

Obama Invokes Newtown on 'Cliff' Deal

Invoking the somber aftermath of the school massacre in Newtown, Conn., President Obama today appealed to congressional Republicans to embrace a standing "fair deal" on taxes and spending that would avert the fiscal cliff in 13 days.

"If there's one thing we should have after this week, it should be a sense of perspective about what's important," Obama said at a midday news conference.

"I would like to think that members of that [Republican] caucus would say to themselves, 'You know what? We disagree with the president on a whole bunch of things,'" he said. "'But right now what the country needs is for us to compromise.'"

House Speaker John Boehner's response: "Get serious."

Boehner announced at a 52-second news conference that the House will vote Thursday to approve a "plan B" to a broad White House deal -- and authorize simply extending current tax rates for people earning less than $1 million a year and little more.

"Then, the president will have a decision to make," the Ohio Republican said. "He can call on Senate Democrats to pass that bill or he could be responsible for the largest tax increase in American history."

'Fiscal Cliff' Negotiations: Deal Might Be Within Reach Watch Video

Unless Congress acts by Dec. 31, every American will face higher income tax rates and government programs will get hit with deep automatic cuts starting in 2013.

Obama and Boehner have been inching closer to a deal on tax hikes and spending cuts to help reduce the deficit. But they have not yet had a breakthrough on a deal.

Obama's latest plan would raise $1.2 trillion in new tax revenue over 10 years, largely through higher tax rates on incomes above $400,000. He also proposes roughly $930 billion in spending cuts, including new limits on entitlement spending, such as slower annual cost-of-living increases for Social Security beneficiaries.

Boehner has agreed to $1 trillion in new tax revenue, with a tax rate hike for households earning over $1 million. He is seeking more than $1 trillion in spending cuts, with significant changes to Medicare and Social Security.

The president said today that he remains "optimistic" about reaching a broad compromise by Christmas because both sides are "pretty close," a sentiment that has been publicly shared by Boehner.

But the speaker's backup plan has, at least temporarily, stymied talks, with no reported contact between the sides since Monday.

"The speaker should return to the negotiating table with the president because if he does I firmly believe we can have an agreement before Christmas," said Sen. Chuck Schumer, D-N.Y., a White House ally.

Schumer said Obama and Boehner are "not that far apart" in the negotiations.

"If they were to come to an agreement by Friday, they could write this stuff over the Christmas break and then we'd have to come back before the New Year and pass it," Schumer said.

Obama said he is "open to conversations" and planned to reach out to congressional leaders over the next few days to try to nudge Republicans to accept a "fair deal."

"At some point, there's got to be, I think, a recognition on the part of my Republican friends that -- you know, take the deal," he told reporters.

"They keep on finding ways to say no, as opposed to finding ways to say yes," Obama added. "At some point, you know, they've got take me out of it and think about their voters and think about what's best for the country."
