Kenyan elephant numbers plummet by 1000 in four years

IT'S a case of up then down for Kenya's second largest population of elephants. After a promising growth spurt, the elephants are now dying faster than they are being born. The decline is being blamed on illegal poaching, driven by Asia's demand for ivory.

The Kenya Wildlife Service recently conducted a census of the Samburu/Laikipia population, the country's second largest. It found that the population lost over 1000 elephants in just four years, and now stands at 6361. Previous censuses in 1992, 1998, 2002 and 2008 had revealed a growing population, which appears to have peaked at 7415 in 2008.

Poaching is suspected. A July report by three conservation groups found that it has been on the rise across Africa since 2006. Poaching is also spreading eastwards from central Africa into countries like Kenya, says Richard Thomas of TRAFFIC in Cambridge, UK, one of the three groups that drafted the report. The July report found that more than half of all elephants found dead in Africa in 2011 had been illegally killed.

The rise in poaching appears to be driven by increasing affluence in China and Thailand, where ivory is often used to make religious sculptures and other decorations.

Organised criminal gangs have capitalised on this increased demand. "If it's worth someone's while to smuggle the ivory, they'll take the risk," Thomas says. There is evidence that gangs are moving into Kenya to hunt elephants.

Boehner in hot seat in game of fiscal chicken

WASHINGTON: With room for maneuver slipping away, top US Republican John Boehner is in a bind over how to avoid going over the fiscal cliff: embrace higher taxes and earn conservatives' ire, or scupper a deal and incur Americans' wrath.

Another option, one that few non-partisans see as very viable, is for President Barack Obama to cave in and agree to Republican demands not to raise taxes, even for the wealthiest Americans.

A likelier resolution is a compromise with the White House that avoids the early January shock of automatic spending cuts coupled with tax hikes on nearly all Americans, while laying out enough deficit reduction that eases concern about the country's financial well-being.

In the game of political chicken to see whether Democrats or Republicans blink first, perhaps the trickiest role of all rests with Speaker of the House Boehner, who along with Obama is the principal in the negotiations.

Boehner's guidance of the Republican position in coming days and weeks could signal much about party direction in the wake of an election that saw flagbearer Mitt Romney -- who advocated slashing tax rates across the board -- defeated by Obama.

"To say Boehner is between a rock and a hard place is minimizing the problem he faces," Boston University professor and longtime political consultant Tobe Berkovitz told AFP.

"Boehner is trying to keep public opinion about Republicans from totally cratering, and at the same time keep the Tea Party hardcore conservatives from totally abandoning the party."

Conservative Republican Trent Franks agrees that "our speaker is in an enormously difficult position."

"And I think he's doing the best he can," the congressman told National Public Radio. "That doesn't mean that what he finally arrives at will be something that I can support or it won't. You know, I don't know."

Few people other than Boehner and Obama know the true state of negotiations in what appears as a well-choreographed campaign to thrash out a last-minute deal.

Discussions appear to have stalled, though, and Boehner has accused Obama of having "wasted another week" by not pushing talks forward.

This weekend Boehner "will be waiting for the White House to respond to our serious offer about averting the fiscal cliff," his spokesman Michael Steel told AFP.

Obama has proposed US$1.6 trillion in new taxes over the next decade from higher rates on the wealthiest two percent of Americans.

Republicans countered with a plan for US$800 billion in tax revenue raised by closing loopholes and ending some deductions. Both plans were rejected.

A Democratic official said Saturday that "nothing has changed since yesterday."

Polls show most Americans want to see taxes rise on the wealthy.

With Obama winning re-election on November 6, and his Democrats gaining seats in both the House and Senate, Republicans concede privately -- and some publicly -- that the Democrats have the upper hand.

"President Obama pretty well holds all the cards in this negotiation," Republican Senator Ron Johnson told Fox News.

"If he wants to have tax increases or tax rates go up, I don't see how Republicans can stop him."

Public trust is not in Boehner's favour. A Washington Post/Pew poll this week showed 53 percent of Americans would blame Republicans should the economy dive off the cliff; 27 percent would blame Democrats.

In his weekly address Saturday, Obama said he was willing to find ways to reduce health costs and make more entitlement spending cuts, but as for asking "the wealthiest Americans to pay higher tax rates -- that's one principle I won't compromise on."

Potential future Republican leaders like Senator Marco Rubio are unlikely to want to bend to White House's will.

Rubio, a possible 2016 presidential candidate, gave the Republican response to Obama's address -- and said "tax increases will not solve our US$16 trillion debt."

Boehner has said that, too, but his position is tenuous. On Friday he left open the possibility for compromise on a tax rate rise.

In past negotiations, such as last December's battle over extending the payroll tax holiday, some Republicans felt Boehner gave away too much.

Hashtags on Twitter -- #boehnermustgo, #fireboehner -- have recently left little doubt that some Republicans are fed up with his handling of the talks.

With conservatives demanding unity on taxes, Boehner faces the prospect of revolt from his right flank should he agree to a deal that would raise high-end rates.

Berkovitz said Republicans face two options if they want to avoid the cliff: negotiate and compromise, or hold their noses and "give Obama what he wants. If it goes south, take the election victory in two years and maybe four years."

Handcuffs that give you an electric shock?

Progress?

(Credit:
Patent Bolt)

Sometimes an invention comes along that makes you excited about the future.

For a long time, it seems that handcuffs have been stuck in the movies of old. They restrain you, but, odd for our interactive world, that's all they seem to do.

Might I tempt you toward futuristic handcuffs that will offer you a small involuntary judder?

I am grateful to Gizmodo for discovering that Patent Bolt has lucked upon a patent that offers bound(less) excitement.

For these are handcuffs that offer surprises. Indeed, they might make the idea of being tased, bro, not quite so bad.

The patent is called "Apparatus and System For Augmented Detainee Restraint."

The augmentations it offers are truly quite something. You see, these handcuffs are "configured to administer electrical shocks when certain predetermined conditions occur."

These shocks might be "activated by internal control systems or by external controllers that transmit activation signals to the restraining device."

This progressive tool is the brainchild of Scottsdale Inventions.

More Technically Incorrect

And while you might be shocked or even excited by the idea of handcuffs with electric shock capabilities, might I move you further?

For Patent Bolt points out that this patent also allows for the idea of a substance delivery system. Yes, these handcuffs might also be used to, well, inject the detained with who knows what -- to achieve "any desired result."

Clearly, the desires of the detained and the detainer might differ. Yet, this patent allows for the possibility of the substance being in the form of "a liquid, a gas, a dye, an irritant, a medication, a sedative, a transdermal medication or transdermal enhancers such as dimethyl sulfoxide, a chemical restraint, a paralytic, a medication prescribed to the detainee, and combinations thereof."

Yes, you really did read the word "paralytic."

Naturally, some will be wondering whether, as in fine restaurants, the arresting officer will ask whether the detained has any allergies.

Some might be concerned, though that -- at least theoretically -- this creation might put quite some power into the hands of those who might not always be lucid or learned enough to use that power wisely.

Plants Grow Fine Without Gravity

When researchers sent plants to the International Space Station in 2010, the flora wasn't meant to be decorative. Instead, the seeds of these small, white flowers—called Arabidopsis thaliana—were the subject of an experiment to study how plant roots developed in a weightless environment.

Gravity is an important influence on root growth, but the scientists found that their space plants didn't need it to flourish. The research team from the University of Florida in Gainesville thinks this ability is related to a plant's inherent ability to orient itself as it grows. Seeds germinated on the International Space Station sprouted roots that behaved like they would on Earth—growing away from the seed to seek nutrients and water in exactly the same pattern observed with gravity. (Related: "Beyond Gravity.")

Since the flowers were orbiting some 220 miles (350 kilometers) above the Earth at the time, the NASA-funded experiment suggests that plants still retain an earthy instinct when they don't have gravity as a guide.

"The role of gravity in plant growth and development in terrestrial environments is well understood," said plant geneticist and study co-author Anna-Lisa Paul, with the University of Florida in Gainesville. "What is less well understood is how plants respond when you remove gravity." (See a video about plant growth.)

The new study revealed that "features of plant growth we thought were a result of gravity acting on plant cells and organs do not actually require gravity," she added.

Paul and her collaborator Robert Ferl, a plant biologist at the University of Florida in Gainesville, monitored their plants from the Kennedy Space Center in Florida using images sent from the space station every six hours.

Root Growth

Grown on a nutrient-rich gel in clear petri plates, the space flowers showed familiar root growth patterns such as "skewing," where roots slant progressively as they branch out.

"When we saw the first pictures come back from orbit and saw that we had most of the skewing phenomenon we were quite surprised," Paul said.

Researchers have always thought that skewing was the result of gravity's effects on how the root tip interacts with the surfaces it encounters as it grows, she added. But Paul and Ferl suspect that in the absence of gravity, other cues take over that enable the plant to direct its roots away from the seed and light-seeking shoot. Those cues could include moisture, nutrients, and light avoidance.

"Bottom line is that although plants 'know' that they are in a novel environment, they ultimately do just fine," Paul said.

The finding further boosts the prospect of cultivating food plants in space and, eventually, on other planets.

"There's really no impediment to growing plants in microgravity, such as on a long-term mission to Mars, or in reduced-gravity environments such as in specialized greenhouses on Mars or the moon," Paul said. (Related: "Alien Trees Would Bloom Black on Worlds With Double Stars.")

The study findings appear in the latest issue of the journal BMC Plant Biology.

Gay Marriage: Will Justices Follow Popular Opinion?

The Supreme Court's announcement that it would hear two cases challenging laws prohibiting same-sex marriage has reinvigorated one of the most hotly contentious social debates in American history, a debate that has been fueled by a dramatic change in attitudes.

With some states taking significant steps towards legalizing gay marriage, the hearings come at a critical moment.

This week in Washington State, hundreds of same-sex couples lined up to collect marriage licenses after Gov. Christine Gregoire announced the passing of a voter-approved law legalizing gay marriage.

"For the past 20 years we've been saying just one more step. Just one more fight. Just one more law. But now we can stop saying 'Just one more.' This is it. We are here. We did it," Gregoire told a group of Referendum 74 supporters during the law's certification.

Washington is just the most recent of several states to pass legislation legalizing same-sex marriage, signifying a significant departure from previous thinking on the controversial subject.

READ: Court to Take Up Same-Sex Marriage

A study by the Pew Research Center on changing attitudes on gay marriage showed that in 2001 57 percent of Americans opposed same-sex marriage, while 35 percent of Americans supported it.

The same poll shows that today opinions have greatly shifted to reflect slightly more support for same-sex marriage than opposition -- with 48 percent of Americans in favor and 43 percent opposed.

In fact, just two years ago, 48 percent of Americans opposed same-sex marriage while only 42 percent supported it -- indicating that opinions have changed dramatically in the last couple of years alone.

Check Out Same-Sex Marriage Status in the U.S. State By State

It's hard to imagine that only 16 years ago, the fervent gay marriage debate led to the conception of the Defense of Marriage Act, which defines marriage as a union solely held between a man and a woman.

While debating the Defense of Marriage Act in September 1996, former Sen. Robert Byrd said: "If same-sex marriage is accepted, then the announcement will be official: America will have said that children do not need a mother and a father. Two mothers or two fathers will be OK. It'll be just as good. This would be a catastrophe."

Even a few short years ago a newly-elected President Obama did not support the legalization of gay marriage. It wasn't until earlier this year, at the end of hiss first term and with the impending election in sight, that the president told ABC's Robin Roberts the he'd "been going through an evolution on this issue."

Obama went on to attribute his shift in stance to the influence of his daughters.

"You know, Malia and Sasha, they've got friends whose parents are same-sex couples. It wouldn't dawn on them that somehow their friends' parents would be treated differently," he said. "That's the kind of thing that prompts -- a change in perspective."

Obama isn't the only one to experience an evolution in thinking on the matter of gay marriage. Attitudes towards same-sex marriage have shifted dramatically over the past decade across the board, particularly in the past few years.

Gone are the days when a majority of people opposed same-sex marriage; the days when gay politicians and supporters of same-sex marriage could not get elected.

Today, nine states and the District of Columbia allow same-sex unions -- a number likely considered inconceivable just a few short years ago. And yet, the same-sex marriage debate still begs for the answering of a question: Will this newfound public opinion, largely driven by young people, women and Democrats, have an effect on the Supreme Court's ultimate decision on the matter?

"I think (gay marriage is) just not a big deal for a lot of young people," Elizabeth Wydra of the Constitutional Accountability Center says. "The justices are human beings so they're not completely immune to public opinion. ... I think the real question for them is going to be do they want to be on the wrong side of history?"

NParks sees healthy increase in volunteer numbers

SINGAPORE: The National Parks Board (NParks) has seen a 33 per cent increase in the number of active volunteers this year, compared to 2011.

Over 800 volunteers now serve on a regular basis and they range from as young as nine years old to over 80. Thirty nine of them have served for more than 10 years.

The volunteers are involved in activities such as leading tours, running programmes and helping out with surveys.

NParks on Saturday honoured its volunteers as part of celebrations for International Volunteer Day, which fell on 5 December, at HortPark.

Dr Leong Chee Chiew, deputy chief executive officer of National Parks Board and Commissioner of Parks and Recreation said: "By making planned programmes like guided walks and talks available to people from all walks of life, our volunteers' efforts have made it possible for everyone to learn more about biodiversity and enjoy nature.

"Thanks to their commitment to various volunteer programmes, they have made it possible for all of us to enjoy a dose of nature as we go about our daily lives.

"Our City in a Garden provides Singaporeans with a high quality of life because of our volunteers."

Hot new games for iOS

The stars lined up just right this week (read: gift-giving season is here!) to have a number of awesome game sequels and new releases launch all at once. Frankly, there are so many new games that there is no better time than the present to check out what the App Store has to offer.

Rick Broida already wrote about Grand Theft Auto: Vice City earlier today, but there are plenty more that would make nice additions to your iOS gaming collection.

This week's collection of apps is a group of excellent games released over the course of this week. The first is a funny and fun dual-stick shooter with tons of weapons to collect. The second is the latest installment in probably the best FPS franchise at the App Store. The third is a port of an old game to the
iPad (and only the iPad), but it might be the most famous classic RPG ever.

Minigore 2: Zombies ($1.99) is the sequel to the fun and funny dual-stick shooter Minigore. The graphics in this zombie-themed sequel still have that funny block-head look, but you're no longer fighting the furry baddies; now you're blowing away the undead.

Part of the fun in the game is John Gore's constant grimace as he blows away zombies.

Much like the first game in the series, Minigore 2 is all about mindless shooting in all directions as hordes of zombies and other creeps try to kill you. You'll also find several melee weapons like swords and giant hammers for close quarters combat. But just when you thought there couldn't be any more zombies swarming around you, a boss will appear that will take a lot of hits to bring down. Fortunately they often also drop a ton of coins so you can upgrade your weapons.

To acquire new weapons, you'll first need to buy them in the store. You get a machine gun for free, but you'll need to purchase new weapons to have them randomly show up in the game for a varied attack. Then, as you collect more coins, you can upgrade your weapons to make them more powerful, unlock new levels, and unlock new characters to play with. Each of the characters can be upgraded as well, helping you last longer against the endless shambling horde. Coins come pretty quickly as you play, so you'll soon be using weapons like shotguns, grenade launchers, and other powerful hardware.

Minigore 2: Zombies is all about mindless fun as you try to complete 300 in-game challenges, blow away 60 different types of enemies, and battle seven giant bosses. If you liked the first Mini Gore game, or just like the mindless action of dual-stick shooters, this sequel is one of the best.

Modern Combat 4: Zero Hour ($6.99) is the latest installment from Gameloft's incredibly popular Modern Combat franchise. While there's not much new gameplay wise, you have more terrorists to kill with a whole new story, and it's still probably the best FPS for the touch screen.

In one level you'll need to clear a path with a remote controlled drone.

In this latest sequel, the game challenges you to fight in countries around the world, from Barcelona to Africa, and you will find and use several different kinds of weapons as you complete mission objectives. In this installment, you will also have the option to play as the villain, giving you a whole different perspective on the game. The game is a universal download, so you can play on any of your iOS devices, but I think it is at its best on the iPad.

You get three different types of control schemes to pick from, with variations of onscreen joysticks and touch-screen actions. I found the default control method to work best for me, using a movement joystick on the left and the touch screen to aim and fire with my right thumb. Some added controls appear in certain situations where you need to pick up an item or jump down from a wall, for example. You can reload your weapon with a single tap on the gun in the upper right or you can double tap to switch weapons as you discover them in the game. One issue here is that the reload button is a little inconvenient (top right of screen) while playing on an iPad, but I was able to get used it after awhile. It still seems like it should be closer to your right thumb.

Though the touch screen will never be as easy to use as a keyboard and mouse or console controller, Modern Combat 4: Zero Hour manages to make the controls fairly easy to use. Auto aim (found in the options) helps a lot to offset the less-than-optimal controls in the beginning, but after spending some time with the game you'll be able turn it off for a more realistic experience.

Along with the fun gameplay, Modern Combat: Zero Hour has amazing graphics, great audio with satisfyingly explosive-sounding guns, and fairly good voice acting in-game and during cut scenes.

When you think you've honed your skills enough, you can take your game online and play in battles of up to 12 players, across eight maps, and in several game modes (FPS staples like Conquest and Capture the Flag are my current favorites). You also have four new specializations for your soldier (chosen before a match) to make him stronger at different strategies like Stealth or Support. Your starting soldier comes with fairly powerful weapons, but you'll need to play several games to earn coins in order to buy new ones. Judging by how populated the servers are so soon after launch, you'll be able to find plenty of games to play do increase your cash.

If you liked any of the earlier installments of Modern Combat, Zero Hour is an excellent choice with more-exciting gameplay, challenging missions, and probably the best graphics yet. If you like first-person shooters, this game is a must-have on your iOS device.

Baldur's Gate Enhanced Edition ($9.99 - iPad Only) is a touch screen recreation of the mega-hit classic RPG adventure game. While a game based on Dungeons and Dragons 2nd Edition rules is not for everyone, if you have the patience, tutorial levels teach you the basics so you can start your adventure.

As you explore dank dungeons, you'll need to use the abilities of every character to survive.

(Credit:
Screenshot by Jason Parker/CNET)

As the port of a game that was originally released in 1998, the graphics are not on par with today's games. Your isometric 3D view from above doesn't show off crystal clear graphics or smooth 3D modeling like you might be used to. But Balder's Gate was a huge fan favorite in its time for its epic storyline and complex gameplay, and the iOS version is a fantastic recreation. So while you won't be dazzled by the graphics, the gameplay definitely holds up, especially if you're a fan of Dungeons and Dragons type role-playing games.

You start by creating your character. Baldur's Gate has three preset options if you want to jump in right away, with a pre-rolled Fighter, Thief, or Mage. But you also can choose to pick from 11 available classes (Druids, Barbarians, Clerics, and more) and set up all the stats yourself, choose your skills or spells, and customize your look. The freedom to set up your own stats means you can customize your character exactly how you want, in effect making the 11 available classes starting points for your perfect character type. It's this type of customization that makes Baldur's Gate great, but it takes some time to learn the ins and outs of all the many skills, so don't expect to just jump in and start hacking away at bad guys.

Once you're in game, you'll quickly realize Baldur's Gate is incredibly complex, requiring you to manage six adventurers all of different classes (Rangers, Druids, Fighters, Wizards, and several others), each with their own abilities that you control. You'll even often need to hit the pause button in the middle of combat in order to plan each characters' moves and actions if you want to stand a chance against the game's many monsters.

To add to the confusion for new players, several skills and spells are not well labeled, making it difficult to pick out the exact action your trying to achieve. Though I was able to figure most of it out with some practice, you should definitely expect a learning curve here. Fortunately, you can experiment all you want in the tutorial levels, and I suggest you try to get familiar with the spell and skill icons before you get too far into the game.

Overall, Baldur's Gate is a faithful recreation of the popular 1998 original with 80 hours of epic RPG adventure and a large world to explore. If you like deep RPG games or played the original Baldur's Gate, this game is a worthwhile purchase.

Federal Agencies Brace for Deep Cuts Post-'Cliff'

Dec 7, 2012 4:22pm

Toby Jorrin/AFP/Getty Images

With the “fiscal cliff” quickly approaching, federal agencies are stepping up preparations for deep automatic budget cuts that will kick in Jan. 2 unless the White House and Congress can reach a deal.

The Office of Management and Budget told ABC News that a memo went out to federal agencies earlier this week seeking “additional information and analysis” in order to finalize spending cuts required if we go off the cliff.

The agencies are considering which workers to furlough, projects to put on hold and offices that will have to close.

The request follows the administration’s release of a 400-page report in September that outlined the budget areas to be impacted by the $1.2 trillion in automatic spending cuts and what percentages they would be slashed.

READ MORE: White House Details ‘Doomsday’ Budget Cuts

Billions of dollars could be slashed from defense operations and maintenance programs. Medicare would take a two-percent hit, trimming millions in payouts to health care providers. Scientific research programs would be gutted. Aid for the poor and needy would be sharply curtailed.

The report also detailed operations that would be exempt from any cuts, including active-duty military operations, nuclear watchdogs, homeland security officials, veterans care and other critical areas.

READ: Pentagon Begins Planning for ‘Cliff’ Cuts

Asked about the agency preparations underway, White House spokesman Jay Carney said Wednesday that OMB “must take certain steps to ensure the administration is ready to issue such an order should Congress fail to act.”

“Earlier this week, OMB issued a request to federal agencies for additional information to finalize calculations on the spending reductions that would be required,” Carney said.

“This action should not be read … as a change in the administration’s commitment to reach an agreement and avoid sequestration.  OMB is simply ensuring that the administration is prepared, should it become necessary to issue such an order,” he said. “OMB will continue to consult with agencies and will provide additional guidance as needed.  This is just acting responsibly because of the potential for this happening.”

Space bigwigs offer billion-dollar private moon trips

Robots aren't the only ones heading to the moon. The first private company offering regular trips to the lunar surface plans to start flights in 2020, shuttling people two at a time on exploratory missions. However, with an expected price tag of $1.4 billion per flight, or around $750 million per person, the trek would likely be out of reach for all but the wealthiest moonwalkers.

Today's announcement, at the National Press Club in Washington, DC backs up recent rumours that Alan Stern, a former administrator of NASA's Science Mission Directorate, had founded a company called Golden Spike in Colorado to run commercial moon trips.

Named for the final spike driven into the first US transcontinental railroad line, Golden Spike plans to market to governments, corporations and individuals to routinely send people to the moon for scientific purposes, to mine for resources or simply for prestige.

"Why the moon? Because it's close, because it's enormous, and because we think that there's going to be a strong market for it," says Stern. No tickets have yet been sold. But preliminary talks with space agencies in Asia and Europe are underway, he adds. "We see our main market as selling expeditions to foreign space agencies."

In 2010 President Barack Obama scrapped NASA's Constellation program for sending astronauts to the moon. Shortly afterwards, Stern convened a secret meeting of heavy-hitters in the space industry in Telluride, Colorado, to discuss the possibility of a private lunar mission. A four-month feasibility study led to the company's quiet founding later that year.

Golden Spike now has several experienced directors and advisors, including Gerry Griffin, former director of NASA's Johnson Spaceflight Center, and Wayne Hale, former chief of NASA's space shuttle programme. It also boasts some colourful characters: Newt Gingrich, a former US presidential candidate who previously championed a lunar colony, and Mike Okuda, a set designer for the Star Trek franchise, are also on the advisory panel.

"One thing you can say about Stern is that he knows the game," says William Whittaker, CEO of Astrobotic Technology, one of many teams competing to put a robot on the moon and win the $20-million Google Lunar X Prize. "As NASA's former science director, he had a favoured insider's perspective. He knows people."

Although several of the firm's directors have NASA experience, Golden Spike will be a purely private enterprise that will not seek government funding, Stern says. The plan is to purchase a rocket and a crew capsule from one or more of the other private space enterprises that have sprung up in recent years, such as SpaceX or Blue Origin.

Golden Spike has signed contracts to begin development of a lunar lander and space suits. Its first lunar mission is expected to cost the company between $7 and $8 billion. To help cover expenses, the company plans to merchandise each mission, for instance, by selling the naming rights for their spacecraft.

Meanwhile, Space Adventures of Arlington, Virginia says it is on track to send people on flights that would circle the moon starting in 2016 or 2017. The price for each flight is $300 million, or $150 million per seat. There are two seats available for the maiden voyage, and one has already been sold, spokesperson Stacey Tearne told New Scientist.

Fred Bourgeois, head of FREDNET, another Lunar X Prize team, worries that the idea of sending people to the moon on private ships is premature. "We need to prove some things with robotic systems first, so we don't put lives at risk," he says. "I would not get on a private mission to the moon today, even though I would love to go."

But Stern says he's confident that robots will get to the moon's surface long before the first Golden Spike flights at the end of the decade. Human beings, he says, will then be needed for activities beyond the capabilities of a robot – from doing field geology to maintaining mining equipment. Says Stern: "We need to start now in order to be ready for the next phase."

Resale prices of non-landed private residential, HDB flats at new highs in Oct & Nov

SINGAPORE: Resale home prices of both non-landed private residential units and HDB flats continued to climb to new highs in October and November against the third quarter 2012.

But according to data released by the Singapore Real Estate Exchange (SRX), the rental market for private homes is showing signs of softening.

As a result, overall gross rental yield dropped to a six-year historic low of 3.77 per cent in the first two months of the fourth quarter.

Meanwhile, prices of private resale homes rose to S$1,222 per square foot (psf) in the first two months of the fourth quarter, up 5.4 per cent from the previous quarter's average of S$1,159 psf.

The report found that resale prices of private homes rose across all regions, with non-landed homes in the suburban region seeing the sharpest increase at 4.5 per cent, compared to the third quarter of 2012.

This is followed by a 3.3 per cent increase in the city fringes and a 2.8 per cent increase in the core central region.

Compared with the first two months of the third quarter this year, transaction volume rose by 6 per cent to reach 2,483 resale transactions in the October to November period.

Meanwhile, the average unit monthly rent of private homes dropped by 1.0 per cent, from S$3.88 psf in the third quarter to S$3.84 in the first two months of forth quarter.

Leading the drop is non-landed homes in the city fringe where prices fell by 2.5 per cent to S$3.91 after rising for the first three consecutive quarters in this year.

The other regions remained relatively stable compared to the previous quarter.

Meanwhile, the report included for the first time data about the sales of small private apartments, commonly known as shoebox units in Singapore.

Year-to-date, just 198 shoebox units changed hands in the resale market.

But the report said there was strong demand for rentals of shoebox units, with 1,328 rental contracts signed this year. This represents 6.7 times more rentals than resales for shoebox units year-to-date. In contrast, the average is 2.4 times more rentals than resales for other types of units.

As a result, shoebox units continue to draw higher rental offers in the fourth quarter.

In the HDB resale market, SRX said overall cash-over-valuation rose to S$34,000 in the first two months into forth quarter. This is S$2,000 shy of the five-year historical high of S$36,000 attained in the third quarter of 2011 since tracking began in 2007.

On a month-to-month basis, overall COV increased from S$33,000 in October to S$35,000 in November.

This has contributed to a 1.1 increase in median prices of HDB flats to a new high of S$455,000, compared to the third quarter.

Overall HDB median rents remained unchanged at S$2,400.

Here comes 'Az' -- one iPad news app closes, another goes live

Screengrab of "AZ" a new iPad magazine launched by Arizona Republic, AZCentral.com and KPNX-TV.

This morning, I had a meeting with a former student who is now the U.S. correspondent for one of the biggest dailies in Europe. He is on a listening tour, helping his newspaper look for innovative ideas that will stave off some of the troubles that American newspapers have had.

Like many places overseas, there's still a strong newspaper culture in his country, but he and his bosses don't want to sit around, waiting for the business to tank. So they are looking for good ideas around the world.

While talking about the demise of "The Daily," Rupert Murdoch's pet
tablet-only project (here's Don Reisinger's CNET take), I told him that it would be easy to draw the wrong lesson.

Just because one, high-profile, expensive attempt at innovation fails doesn't mean that we should all stop trying. There will be others experiments to watch, I told him.

A few hours later, I got an alert about someone else playing in the
iPad space, but this time, it was not launching in New York City.

I received an email from Keira Nothaft, senior director/news publishing and programming, at the Arizona Republic. She works on AZCentral.com, which is a joint effort of the newspaper and the local NBC affiliate, KPNX-TV. In it, she described "AZ," which she called "a significant development in the evolution of newspaper-to-digital publishing" - an evening news magazine for the iPad. It will be published once a week through January and then move to Monday-Friday after that. It's free until February, with Android and
Kindle versions en route.

I've been playing with "AZ" (downloadable here, or search "AZ Today" in the App Store) over the past hour and have been impressed so far. Big, beautiful photographs, strong graphics and punchy stories that make use of iPad's functionality. This isn't just a tablet version of the website, but a magazine-like experience broken up into four chapters to: "Inform you about the world. Engage you with storytelling. Entertain you with the world of sports. Amuse you with the fun features you want every time."

I like to see media companies try new things. Nothaft's e-mail explains why her team is doing this:

Like most legacy media outlets, The Arizona Republic is striving to hold onto print readership while simultaneously building a profitable digital audience. We're in a good position, though, because we're the biggest newspaper in the state, the leading news TV station in the market and one of the largest news websites in the country. But we recognize we need to do more.

Until recently, almost every newspaper in America gave away their content online, but now many are moving to various versions of a paywall (one count as 20 percent using paywalls). The Republic's readers, Nothaft explains, are being asked "to pay to subscribe to content in all its forms, on many different platforms. In return, the newsroom would deliver more -- more great storytelling, more watchdog reporting, more great multimedia. The app is free until February, when it will be included with every full-access subscription, for everyone who owns an iPad."

Other points she makes in her note:

AZ is timed to be released when people are using their tablets the most, in the evening, with time to lean back and sink into an immersive read. We know that about 70 percent of tablet usage is in the home between the hours of 5 p.m. and 11 p.m. While AZ will draw on content produced by the Republic newsroom, as well as original photo, video and text, it will go far beyond a typical duplication of a newspaper website. Editors will create, curate and tailor the content for the tablet, keeping in mind the different demands and pleasures afforded by the digital reading experience.

There's a market for smart, sophisticated, interactive journalism - in metro Phoenix, 14 percent of all adults, more than half a million people, already own and use a tablet. The number's growing every day.

Nothaft shares how this experiment differs from "The Daily," including the geography:

We think it's a significant development for a newspaper to have such an aggressive and unique tablet strategy. We also think the timing is interesting, coming as another tablet experiment, The Daily, folds. We're approaching AZ as a startup, using existing resources and minimal investment. (Though, I challenge anyone to differentiate the sophistication of this multimedia magazine from anything that's produced in Midtown Manhattan.) The financial model differs from The Daily in that subscribers to AZ will gain access to our suite of digital products that includes the magazine, other tablet apps, mobile and desktop. And for print readers, the tablet magazine and all of our digital products is included with their subscription. The strategy is to increase the satisfaction of current subscribers and gain nontraditional newspaper readers. The magazine will include ads beginning with the new year.

If you don't have an iPad, you can get a sense of the publication by see this slideshow.

  Twin probes circling the moon—part of NASA's GRAIL mission—since 2011 have been recording changes in gravity as they fly over peaks and valleys on the lunar surface. As one probe flies over an area with a greater gravity field, the washing-machine-size instrument speeds up slightly, increasing the distance between it and its sister probe. These minute changes in position have enabled scientists to construct this very detailed view of local changes in the moon's gravity.

  In this artist's conception of fine-grained particles around a brown dwarf—or a failed star—bits of debris are on their way to becoming a rocky planet.

  Current thinking on Earthlike, rocky planet formation says that random collisions between tiny debris occur in the disc of material surrounding newborn stars. But the recent discovery of such a disc surrounding a brown dwarf has some astronomers rethinking that hypothesis. If planets can form from the debris around these failed stars, then rocky planets may be much more common than previously thought.

  The Suomi NPP satellite captured this nighttime image of the aurora australis over the Antarctic coast south of South Africa. Despite the winter darkness and a waning crescent moon, the auroras produced enough light for sensors on board the new NASA and National Oceanic and Atmospheric Administration satellite to capture the boundary between the ice shelf and what some scientists call the Southern, or Antarctic, Ocean (dark line across the bright center swirl).

  Launched last year, Suomi NPP enables scientists to capture nighttime images of the Earth's atmosphere and surface. The new sensor is so sensitive, it can capture the lights from one ship at sea.

Direct confirmation is difficult, however, since Venus's thick atmosphere precludes a peek at its peaks.

John McAfee Out of Hospital, Back in Cell

Software millionaire John McAfee has been returned to an immigration detention cell in Guatemala after being rushed to a Guatemala City hospital via ambulance.

McAfee, 67 -- who soon may be deported back to Belize, where authorities want to question him about the shooting death of his neighbor -- was reportedly found prostrate on the floor of his cell and unresponsive.

He was wheeled into the hospital on a gurney. Photographers followed in pursuit right into the emergency room, but as emergency workers eased McAfee's limp body from the gurney and onto a bed and began to remove his suit, he suddenly spoke up, saying, "Please, not in front of the press."

Earlier today, McAfee had complained of chest pains, raising concerns he might be having a heart attack.

However, that did not appear to be the case. Hours after his emergency, hospital officials sent McAfee back to the detention center, telling ABC News they found no reason to keep him overnight.

In a phone interview overnight, McAfee told ABC News, "I simply passed out, everything went black."

He said he hit his head on the floor when he collapsed. McAfee explained that for the past 48 hours he hasn't eaten and had very little to drink.

McAfee had been scheduled to be deported to Belize, ABC News has learned. But a judge could stay the ruling if it is determined that McAfee's life is threatened by being in Belizean custody, as McAfee has claimed in the past several weeks.

McAfee's attorneys hope to continue delaying the deportation by appealing to the Guatemala's high court on humanitarian grounds.

Raphael Martinez, a spokesman for the Belize government, said that if McAfee is deported to Belize, he would immediately be handed over to police and detained for up to 48 hours unless charges are brought against him.

"There is more that we know about the investigation, but that remains part of the police work," he said, hinting at possible charges.

He added that a handover by Guatemala would be "the neighborly thing to do."

A spokesman for the U.S. embassy in Guatemala said that "due to privacy considerations," the embassy would "have no comment on the specifics of this situation," but that, "U.S. citizens are subject to the laws of the countries in which they are traveling or residing, and must work within the host countries' legal framework."

Just hours before McAfee's arrest, he told ABC News in an exclusive interview Wednesday he would be seeking asylum in Guatemala. McAfee was arrested by the Central American country's immigration police and not the national police, said his attorney, who was confident his client would be released within hours.

"Thank God I am in a place where there is some sanity," said McAfee before his arrest. "I chose Guatemala carefully."

McAfee said that in Guatemala, the locals aren't surprised when he says the Belizean government is out to kill him.

"Instead of going, 'You're crazy,' they go, 'Yeah, of course they are,'" he said. "It's like, finally, I understand people who understand the system here."

But McAfee added he has not ruled out moving back to the United States, where he made his fortune as the inventor of anti-virus software, and that despite losing much of his fortune he still has more money than he could ever spend.

In his interview with ABC News, a jittery, animated but candid McAfee called the media's representation of him a "nightmare that is about to explode," and said he's prepared to prove his sanity.

McAfee has been on the run from police in Belize since the Nov. 10 murder of his neighbor, fellow American expatriate Greg Faull.

During his three-week journey, said McAfee, he disguised himself as handicapped, dyed his hair seven times and hid in many different places during his three-week journey.

He dismissed accounts of erratic behavior and reports that he had been using the synthetic drug bath salts. He said he had never used the drug, and said statements that he had were part of an elaborate prank.

Investigators said that McAfee was not a suspect in the death of the former developer, who was found shot in the head in his house on the resort island of San Pedro, but that they wanted to question him.

McAfee told ABC News that the poisoning death of his dogs and the murder just hours later of Faull, who had complained about his dogs, was a coincidence.

McAfee has been hiding from police ever since Faull's death -- but Telesforo Guerra, McAfee's lawyer in Guatemala, said the tactic was born out of necessity, not guilt.

"You don't have to believe what the police say," Guerra told ABC News. "Even though they say he is not a suspect they were trying to capture him."

Guerra, who is a former attorney general of Guatemala, said it would take two to three weeks to secure asylum for his client.

According to McAfee, Guerra is also the uncle of McAfee's 20-year-old girlfriend, Samantha. McAfee said the government raided his beachfront home and threatened Samantha's family.

"Fifteen armed soldiers come in and personally kidnap my housekeeper, threaten Sam's father with torture and haul away half a million dollars of my s***," claimed McAfee. "If they're not after me, then why all these raids? There've been eight raids!"

Before his arrest, McAfee said he would hold a press conference on Thursday in Guatemala City to announce his asylum bid. He has offered to answer questions from Belizean law enforcement over the phone, and denied any involvement in Faull's death.

Chemical key to cell division revealed

In each of our cells, most of the genetic material is packaged safely within the nucleus, which is protected by a double membrane. The biochemistry behind how this membrane transforms when cells divide has finally been unravelled, offering insights that could provide new ways of fighting cancer and some rare genetic disorders.

During cell division, the membrane that surrounds the nucleus breaks down and reforms in the two daughter cells. Researchers have been split on the precise mechanisms that govern membrane reformation. One view is that proteins alone control the membrane's transformations. Another possibility is that changes in lipids – a vast group of fat-related compounds – are responsible.

Experiments had failed to show which of these two ideas was right, because it was difficult to alter lipid levels in specific compartments of cells without affecting other cellular processes.

Banafshe Larijani at Cancer Research UK's London Research Institute and her colleagues have now overcome that hurdle. They came up with a technique that transforms a type of lipid called a diacylglycerol (DAG) into another lipid, within the nuclear membrane.

Chemical cascade

The technique involves inserting two fragments of DNA into the nucleus of a cell. This causes the cell to make two proteins: the first attaches itself to the nuclear membrane, the second floats around the cell. Adding a drug – rapalogue – to the mix causes the second protein to stick to the first, which in turn causes a chemical cascade that transforms the DAG into a different kind of lipid.

Crucially, they targeted a form of DAG that does not bind to proteins, so converting it into a different lipid does not affect any processes involving proteins in the cell.

The team tested the effect of this lipid manipulation on cell division in monkey and human cancer cells. The lower the level of DAG present in the nuclear membrane, the greater the membrane malformation and chance of cell death.

This demonstrates that lipids play a role in nuclear membrane reformation that does not depend on proteins.

Larijani says it "opens the door to finding ways to kill cancerous cells" by focusing on lipids that are important to the nuclear membrane's development.

Sausage pieces

As the nucleus divides, sausage-shaped fragments of its membrane float around the cell. The fragments have curved ends, and Larijani says that changes in lipid composition generate these curves, without which the fragments cannot reassemble correctly into new membranes.

More than a dozen rare genetic conditions such as Hutchinson-Gilford progeria syndrome, which is characterised by premature ageing in children, have been linked to irregularities in cell division. A better understanding of the way the nuclear membrane forms when cells divide could be key to treating these disorders.

The research also offers a new focus for preventing the irregular cell division that underlies many cancers.

"As a result of this work we now know with confidence that DAG plays a structural role in membrane dynamics," says Vytas Bankaitis, at the Texas A&M Health Science Center in College Station, who was not involved in the study. "If we could find a molecule with suitable characteristics, this manipulation could be done [in humans], which is something that has not really been considered before."

4 ex-SMRT bus drivers from China charged with instigating strike granted bail

SINGAPORE: The four ex-SMRT drivers from China who have been charged with instigating an illegal strike have been granted bail on Thursday.

He Jun Ling, who faces two charges of inciting SMRT drivers to take part in the strike on 26 and 27 November, was granted bail of S$20,000. His passport will have to be impounded.

According to court documents, He, 32, also made an online post about the strike on Chinese website Baidu, allegedly asking other workers to go on MC together.

Gao Yue Qiang, 32, Wang Xian Jie, 39 and Liu Xiang Ying, 33, were granted bail of S$10,000 each. Their passports will have to be impounded.

In response to a question from District Judge May Lucius Mesenas, the four accused said they're not able to raise the money.

Two officials from the Chinese embassy were present in court.

Bask in Earth's nighttime glow as seen from space

When the skies darken and the lights flicker on, the areas of Earth we populate gain a surreal glow that traces our existence in a breathtaking way.

A new series of photos released by NASA and the National Oceanic and Atmospheric Administration's jointly-operated Suomi NPP satellite gives us a clearer view than ever before at our illuminated world during nighttime. Perhaps you could compare the view to a series of electrified blood vessels and arteries.

CNET photojournalist James Martin compiled a gallery of these stunning images from the aforementioned agencies that shows off the amazing electric show that comes from continents such as the suburban sprawl of North America to the blazing oil fields of the Middle East. The project, known as the "Black Marble," required 312 orbits and the extremely powerful Visible Infrared Imaging Radiometer Suite (VIIRS) sensor to capture 2.5 terabytes of pictures. Cloudless shots compiled from the massive amount of data was then sewn on to the classic 1994 'Blue Marble' imagery for the clearest glimpse of visible light at night seen yet.

You can tell the dramatic examples of how life differs from country to country in the series of photos, such as the sweeping darkness over the Midwest U.S. and the bright coastal areas, or the stark contrast of power usage between the dimly lit North Korea and the hyper-bright South Korea. Additionally, if you look closely at the picture of Australia, you'll notice half the continent lit up from the wildfires that occurred earlier this year.

A 2020 Rover Return to Mars?

NASA is so delighted with Curiosity's Mars mission that the agency wants to do it all again in 2020, with the possibility of identifying and storing some rocks for a future sample return to Earth.

The formal announcement, made at the American Geophysical Union's annual fall meeting, represents a triumph for the NASA Mars program, which had fallen on hard times due to steep budget cuts. But NASA associate administrator for science John Grunsfeld said that the agency has the funds to build and operate a second Curiosity-style rover, largely because it has a lot of spare parts and an engineering and science team that knows how to develop a follow-on expedition.

"The new science rover builds off the tremendous success from Curiosity and will have new instruments," Grunsfeld said. Curiosity II is projected to cost $1.5 billion—compared with the $2.5 billion price tag for the rover now on Mars—and will require congressional approval.

While the 2020 rover will have the same one-ton chassis as Curiosity—and could use the same sky crane technology involved in the "seven minutes of terror"—it will have different instruments and, many hope, the capacity to cache a Mars rock for later pickup and delivery to researchers on Earth. Curiosity and the other Mars rovers, satellites, and probes have garnered substantial knowledge about the Red Planet in recent decades, but planetary scientists say no Mars-based investigations can be nearly as instructive as studying a sample in person here on Earth.

(Video: Mars Rover's "Seven Minutes of Terror.")

Return to Sender

That's why "sample return" has topped several comprehensive reviews of what NASA should focus on for the next decade regarding Mars.

"There is absolutely no doubt that this rover has the capability to collect and cache a suite of magnificent samples," said astronomer Steven Squyres, with Cornell University in New York, who led a "decadal survey" of what scientists want to see happen in the field of planetary science in the years ahead. "We have a proven system now for landing a substantial payload on Mars, and that's what we need to enable sample return."

The decision about whether the second rover will be able to collect and "cache" a sample will be up to a "science definition team" that will meet in the years ahead to weigh the pros and cons of focusing the rover's activity on that task.  

As currently imagined, bringing a rock sample back to Earth would require three missions: one to select, pick up, and store the sample; a second to pick it up and fly it into a Mars orbit; and a third to take it from Mars back to Earth.

"A sample return would rely on all the Mars missions before it," said Scott Hubbard, formerly NASA's "Mars Czar," who is now at Stanford University. "Finding the right rocks from the right areas, and then being able to get there, involves science and technology we've learned over the decades."

Renewed Interest

Clearly, Curiosity's success has changed the thinking about Mars exploration, said Hubbard. He was a vocal critic of the Obama Administration's decision earlier this year to cut back on the Mars program as part of agency belt-tightening but now is "delighted" by this renewed initiative.

(Explore an interactive time line of Mars exploration in National Geographic magazine.)

More than 50 million people watched NASA coverage of Curiosity's landing and cheered the rover's success, Hubbard said. If things had turned out differently with Curiosity, "we'd be having a very different conversation about the Mars program now."

(See "Curiosity Landing on Mars Greeted With Whoops and Tears of Jubilation.")

If Congress gives the green light, the 2020 rover would be the only $1 billion-plus "flagship" mission—NASA's largest and most expensive class of projects—in the agency's planetary division in the next decade. There are many other less ambitious projects to other planets, asteroids, moons, and comets in the works, but none are flagships. That has left some planetary scientists not involved with Mars unhappy with NASA's heavy Martian focus.

Future Plans

While the announcement of the 2020 rover mission set the Mars community abuzz, NASA also outlined a series of smaller missions that will precede it. The MAVEN spacecraft, set to launch next year, will study the Martian atmosphere in unprecedented detail; a lander planned for 2018 will study the Red Planet's crust and interior; and NASA will renew its promise to participate in a European life-detection mission in 2018. NASA had signed an agreement in 2009 to partner with the European Space Agency on that mission but had to back out earlier this year because of budget constraints.

NASA said that a request for proposals would go out soon, soliciting ideas about science instruments that might be on the rover. And as for a sample return system, at this stage all that's required is the ability to identify good samples, collect them, and then store them inside the rover.

"They can wait there on Mars for some time as we figure out how to pick them up," Squyres said. "After all, they're rocks."
