Driverless car concept gains traction at CES

LAS VEGAS: Automakers and technology firms are jumping on the bandwagon of the driverless car, which remains a concept as well as a platform for new technologies to improve safety on the road.

At the Consumer Electronics Show in Las Vegas this week, Toyota and Audi showed off their ideas for autonomous vehicles, in the wake of the push by Google on its driverless car. And others may follow suit.

Toyota drew considerable attention with its electronically gussied-up Lexus sedan, equipped with a host of sensors and cameras that can detect what is around the vehicle.

"It has the ability to drive itself, but we won't allow it," said Jim Pisz, corporate manager at Toyota North America.

Pisz said the technology is similar to Google's with the use of electronics, but that "the Google focus is on software mapping, that's what they're really good at. Toyota focuses on safety programs and more integrated programs."

The Japanese automaker maintains that its 2013 Lexus LS, also being shown at the expo, already has "the world's most advanced pre-collision safety system" but its driverless cars are only being used in closed research centres, unlike Google's publicised road tours.

The growing use of advanced electronics for auto safety, communications and entertainment has prompted a record eight automakers to attend the Las Vegas show, along with dozens of firms working on related products and services.

"Electronics are vital to our cars. Today's cars are rolling computers," Audi executive Wolfgang Duerheimer told reporters at CES.

The German automaker's Ulrich Hofmann told AFP that the new technology "helps the driver in situations where it's boring to drive, and leaves you to drive when it is fun."

At the Las Vegas tech confab, Audi showed its concept for a driverless vehicle in a simulator.

Hofmann said an autonomous car could be developed within five to eight years but noted that "there are a lot of regulatory and legal issues."

Ford Motor Co. researcher Pim van der Jagt said the US auto giant halted its program on driverless cars several years ago.

The concert "seemed so far out, it didn't make sense having big teams working on it," he said, but added that "now, with the interest in the Google car, politicians are starting to speak about it" and Ford has resumed its program.

Nevertheless, "a full autonomous car is far out, and may even never exist," van der Jagt said.

Audi engineers say they can envision an on-off switch which could be used in traffic jams on highways, where vehicles could join a sort of motorcade traveling at identical speeds, freeing a driver for a few moments.

In September, California Governor Jerry Brown signed a bill clearing the way for self-driving cars to jockey with human-operated vehicles to test the technology on the state's roads.

The state of Nevada in May issued a license plate giving Google's self-driving car the green light to travel along public roads there.

The growing talk of autonomous cars has sparked fresh interest in how the tech sector -- which has been under fire for fuelling "distracted driving" -- can improve auto safety and the driving experience.

"Everybody gets distracted at some point," said Steven Wenger of Mobileye, a company that makes equipment for crash avoidance for major automakers and as a consumer aftermarket device.

"Three seconds could save a person's life. We want people to be aware of these technologies which can help avoid accidents."

BlackBerrify your iPhone with Spike keyboard case

LAS VEGAS--No one likes typing on a touch screen. So what if your iPhone case had a very mini QWERTY keyboard?

That's just what Spike from SoloMatrix is designed to be. When we heard about it last year, the Spike TypeSmart keyboard was part of a Kickstarter campaign that proved successful.

The tactile keyboard swivels out from its case and its keys make contact with the iPhone's on-screen keyboard.

It doesn't require separate charging, docking, or an app, and it works with capacitive conductivity through the screens on the
iPhone 4 and
iPhone 5.

Whenever a key is pressed and makes contact with the screen, it creates a grounded state.

Spike attaches to the phones in a snap. There's a number key that pushes the number menu on the iPhone's on-screen keyboard. Then you can type using the alternate number designations for the TypeSmart.

But your fingers better be very nimble indeed to get the hang of it. When I tried typing a few sentences, certain keys didn't register and words were missing letters.

I have a BlackBerry Curve, and there's really no comparison between the ease of use of its keyboard and Spike. The former wins hands down.

But if you want something very compact that doesn't require separate power or Bluetooth, Spike may be worth considering.

The iPhone 4/4s version will launch in February for $49.95, with the iPhone 5 edition following.

The price may drop if there's high order volume, according to Cody Solomon, SoloMatrix co-founder.

Since the campaign raised some $81,000, Spike could prove popular indeed.

Pictures: Wildfires Scorch Australia Amid Record Heat

Photograph by Jo Giuliani, European Pressphoto Agency

Smoke from a wildfire mushrooms over a beach in Forcett, Tasmania, on January 4. (See more wildfire pictures.)

Wildfires have engulfed southeastern Australia, including the island state of Tasmania, in recent days, fueled by dry conditions and temperatures as high as 113ºF (45ºC), the Associated Press reported. (Read "Australia's Dry Run" inNational Geographic magazine.)

No deaths have been reported, though a hundred people are unaccounted for in the town of Dunalley, where the blazes destroyed 90 homes.

"You don't get conditions worse than this," New South Wales Rural Fire Service Commissioner Shane Fitzsimmons told the AP.

"We are at the catastrophic level, and clearly in those areas leaving early is your safest option."

Dead Lotto Winner's Wife Seeks 'Truth'

The wife of a $1 million Chicago lottery winner who died of cyanide poisoning told ABC News that she was shocked to learn the true cause of his death and is cooperating with an ongoing homicide investigation.

"I want the truth to come out in the investigation, the sooner the better," said Shabana Ansari, 32, the wife of Urooj Khan, 46. "Who could be that person who hurt him?

"It has been incredibly hard time," she added. "We went from being the happiest the day we got the check. It was the best sleep I've had. And then the next day, everything was gone."

Ansari, Khan's second wife, told the Chicago Sun-Times that she prepared what would be her husband's last meal the night before Khan died unexpectedly on July 20. It was a traditional beef-curry dinner attended by the married couple and their family, including Khan's 17-year-old daughter from a prior marriage, Jasmeen, and Ansari's father. Not feeling well, Khan retired early, Ansari told the paper, falling asleep in a chair, waking up in agony, then collapsing in the middle of the night. She called 911.

Khan, an immigrant from India who owned three dry-cleaning businesses in Chicago, won $1 million in a scratch-off Illinois Lottery game in June and said he planned to use the money to pay off his bills and mortgage, and make a contribution to St. Jude Children's Research Center.

"Him winning the lottery was just his luck," Ansari told ABC News. "He had already worked hard to be a millionaire before it."

Jimmy Goreel, who worked at the 7-Eleven store where Khan bought the winning ticket, described him to The Associated Press as a "regular customer ... very friendly, good sense of humor, working type of guy."

Khan's unexpected death the month after his lottery win raised the suspicions of the Cook County medical examiner. There were no signs of foul play or trauma so the death initially was attributed to arteriosclerotic cardiovascular disease, which covers heart attacks, stroke or ruptured aneurysms. The medical examiner based the conclusion on an external exam -- not an autopsy -- and toxicology reports that indicated no presence of drugs or carbon monoxide.

Khan was buried at Rosehill Cemetery in Chicago.

However, several days after a death certificate was issued, a family member requested that the medical examiner's office look further into Khan's death, Cook County Medical Examiner Stephen Cina said. The office did so by retesting fluid samples that had been taken from Khan's body, including tests for cyanide and strychnine.

When the final toxicology results came back in late November, they showed a lethal level of cyanide, which led to the homicide investigation, Cina said. His office planned to exhume Khan's body within the next two weeks as part of the investigation.

Melissa Stratton, a spokeswoman for the Chicago Police Department, confirmed it has been working closely with the medical examiner's office. The police have not said whether or not they believe Khan's lottery winnings played a part in the homicide.

Khan had elected to receive the lump sum payout of $425,000, but had not yet received it when he died, Ansari told the AP, adding that the winnings now are tied up as a probate matter.

"I am cooperating with the investigation," Ansari told ABC News. "I want the truth to come out."

Authorities also have not revealed the identity of the relative who suggested the deeper look into Khan's death. Ansari said it was not her, though she told the AP she has subsequently spoken with investigators.

"This is been a shock for me," she told ABC News. "This has been an utter shock for me, and my husband was such a goodhearted person who would do anything for anyone. Who would do something like this to him?

"We were married 12 years [and] he treated me like a princess," she said. "He showered his love on me and now it's gone."

Tony Fadell: From iPhones to sexing up thermostats

After quitting Apple, the tech guru behind the iPod wanted to revolutionise our homes – starting with the humble thermostat

After you left Apple, you developed a "smart" thermostat. Was that always your plan?
Not at all! The plan was to retire with my wife, who also worked for Steve [Jobs], and spend time with our children. We didn't see them because we were working so madly at Apple. We wanted to build a house in Lake Tahoe. I wanted to design the greenest, most connected house that I could. That's when I found out about the thermostat problem. These devices had not seen innovation in 30 years. They were the same as the ones our parents had. I wanted something that was very different.

Your solution was the NEST. Tell me about it
It uses algorithms and sensors to remember the temperatures you like, create a custom schedule for your home and turn itself down when you are away. And you can use your smartphone, tablet or computer to control it remotely. We call it the thermostat for the iPhone generation. It has a big dial, not fiddly buttons.

Did Steve Jobs have any input?
I was going to talk to Steve about it. He knew we were working on something, but he didn't know what. When it was time to show him, he said he couldn't do it. Unfortunately, he died just a few weeks later, before he could see it.

Is the NEST just the start of a range of smart-home devices?
Absolutely. But if you look at what we did at Apple after the iPod came out, it took us five years to start thinking about the iPhone and two more years to finally ship it. I would love to make more devices, but our goal is to make the NEST successful first.

Who would have believed the iPod could turn into the iPhone, then the iPad?
Even I wondered how many people would buy an iPad. But you have to be at the right place in the cultural time. We plan a similar trajectory with the NEST, with the ways that emerging behaviours can happen in the home through interconnected devices. You can't start with all of these things at once because people's minds get blown. You start with very simple things, simple concepts, and then you can build on them.

Will people have to continually upgrade their thermostats, as they do with cellphones?
Unlike a cellphone, you're not going to change the NEST every 18 months! They are supposed to hang on your wall for 10 to 15 years. Our goal is to continue to improve it via software, and we have built tonnes of extra capability into this device to allow that to happen. For example, we have a new update that gives an energy report - it shows how you're doing compared with last month, and even compares you to your neighbours.

Was it your aim to raise awareness of the energy we waste heating our homes?
The NEST starts people thinking about how they're using energy in the home. But it's also a great party trick. You get people whipping out their phones and saying "Check out my NEST at home! Watch, I'm going to freeze my wife!"

Japan to buy Europe bonds to soothe debt crisis

TOKYO: Japan's new finance minister said that Tokyo would buy bonds issued by Europe's permanent bailout fund to help soothe the eurozone's debt problems and stabilise the yen.

Taro Aso told reporters the new government would tap foreign exchange reserves to pay for the bonds, but declined to say how much it planned to buy.

A finance ministry told AFP the bond buying could start as early as Tuesday, when the European Stability Mechanism (ESM) begins selling the paper, adding that Japan "will make a purchasing decision after seeing the terms of the issuance".

Japan, which counts Europe as a major export market, previously purchased billions of dollars in bonds issued by the ESM's predecessor, the European Financial Stability Facility.

"Stabilising Europe's financial crisis will eventually contribute to the stability of currency (prices) including the yen, and so we plan to keep purchasing ESM bonds using foreign reserves," Aso said Tuesday.

Europe's debt crisis has seen four countries ask for bailout cash to help pay their bills, while there were fears that others including Italy and Spain would follow suit as their borrowing costs surged.

However, those concerns have eased since September, when the European Central Bank promised to buy the bonds of struggling nations to keep rates down.

Also Tuesday, Japanese media reported that Tokyo was considering an extra budget worth about $150 billion to boost the limp economy, with about 40 percent of that figure directed toward public works projects.

The yen hit record highs around 75 against the dollar in late 2011, sparking panic among Japanese exporters whose goods are made more expensive by a strong currency.

However, the unit has since weakened and has seen a steep decline in recent weeks as the new government of Shinzo Abe, which took office last month after a landslide election win, vows to press the Bank of Japan for more aggressive monetary easing.

Reports Tuesday quoted Japanese executives expressing concern about the yen's recent tumble, saying the quick decline could pose a danger to the Japanese economy.

The business community, which had pressed officials for months to tame the surging yen, say a further plunge in the currency could shake investor confidence.

A weaker currency also makes fuel imports, which have risen steeply in the wake of Japan shutting down its nuclear plants, more expensive.

In Tokyo forex trading on Tuesday afternoon, the euro was up at 115.00 yen from 114.75 yen before Aso's comments, while the dollar bought 87.66 yen from 87.48 yen in morning deals.

Europe's permanent bailout fund was initially supposed to come online in July but only became operational in October after it was delayed by a challenge at the German Constitutional Court.

Freaky-awesome massage vest rubs you up with your own tunes

CNET Crave blogger Amanda Kooser gets a "Gangnam Style" massage.

(Credit:
Amanda Kooser/CNET)

LAS VEGAS--If you ever wanted to know what it would feel like to have Mick Jagger massage out the knots in your back muscles while you listen to "Tumbling Dice," then I have the perfect gadget for you. The iMusic BodyRhythm massage vest sits over your shoulders and upper back. Plug it into your iPhone, fire up the app, and enjoy a rub down to the beat of your favorite song.

I got to try out a fully-functioning prototype of the vest at
CES 2013. The vest's creator Uwe Diegel hooked me up with some "Gangnam Style" massage action. I could see going for the full-album experience and having an extended session with "Exile on Main Street." It would be a very different way of experiencing the music.

The app doesn't just mine the massage possibilities of your music collection. It can also be used like a personal drum machine where you trigger your own massage beats. If you really want to get crazy with it, then you can set it to react to shaking the iPhone. I tried out this mode and it feels like having half a dozen cats dancing on your back.

Diegel says that the vest isn't a medical device so much as a fun way to relax while enjoying your favorite music. He sounds a bit bemused that he has spent a considerable amount of time designing medical devices, but this oddball creation is getting all the attention. Diegel has gotten enough encouragement for the concept to launch a Kickstarter project.

A $69 super-early-bird pledge will get you a vest of your own should the Kickstarter project reach its $50,000 goal. The regular pre-order price is $149.

There is something both surreal and comforting about this vest. Even though I wore it in public at CES, I can't really see wearing it in public. Still, in the privacy of my own home, with avglass of champagne and some Nick Lowe, this might be just the ticket for a relaxing evening in.

Primitive and Peculiar Mammal May Be Hiding Out in Australia

It’d be hard to think of a mammal that’s weirder than the long-beaked, egg-laying echidna. Or harder to find.

Scientists long thought the animal, which has a spine-covered body, a four-headed penis, and a single hole for reproducing, laying eggs, and excreting waste, lived only in New Guinea. The population of about 10,000 is critically endangered. Now there is tantalizing evidence that the echidna, thought to have gone extinct in Australia some 10,000 years ago, lived and reproduced there as recently as the early 1900s and may still be alive on Aussie soil.

The new echidna information comes from zoologist Kristofer Helgen, a National Geographic emerging explorer and curator of mammals at the Smithsonian Institution. Helgen has published a key finding in ZooKeys confirming that a skin and skull collected in 1901 by naturalist John T. Tunney in Australia is in fact the western long-beaked echidna, Zaglossus bruijnii. The specimen, found in the West Kimberley region of Western Australia, was misidentified for many years.

(More about echidnas: Get to know this living link between mammals and reptiles.)

Helgen has long been fascinated by echidnas. He has seen only three in the wild. “Long-beaked echidnas are hard to get your hands on, period,” he said. “They are shy and secretive by nature. You’re lucky if you can find one. And if you do, it will be by chance.” Indeed, chance played a role in his identification of the Australian specimen. In 2009, he visited the Natural History Museum of London, where he wanted to see all of the echidnas he could. He took a good look in the bottom drawer of the echidna cabinet, where the specimens with less identifying information are often stored. From among about a dozen specimens squeezed into the drawer, he grabbed the one at the very bottom.

(Related from National Geographic magazine: “Discovery in the Foja Mountains.”)

“As I pulled it out, I saw a tag that I had seen before,” Helgen said. “I was immediately excited about this label. As a zoologist working in museums you get used to certain tags: It’s a collector’s calling card. I instantly recognized John Tunney’s tag and his handwriting.”

John Tunney was a well-known naturalist in the early 20th century who went on collecting expeditions for museums. During an Australian expedition in 1901 for Lord L. Walter Rothschild’s private museum collection, he found the long-beaked echidna specimen. Though he reported the locality on his tag as “Mt Anderson (W Kimberley)” and marked it as “Rare,” Tunney left the species identification field blank. When he returned home, the specimen was sent to the museum in Perth for identification. It came back to Rothschild’s museum identified as a short-beaked echidna.

With the specimen’s long snout, large size, and three-clawed feet, Helgen knew that it must be a long-beaked echidna. The short-beaked echidna, still alive and thriving in Australia today, has five claws, a smaller beak, and is half the size of the long-beaked echidna, which can weigh up to 36 pounds (16 kilograms).

As Helgen began tracing the history and journey of the specimen over the last century, he crossed the path of another fascinating mind who had also encountered the specimen. Oldfield Thomas was arguably the most brilliant mammalogical taxonomist ever. He named approximately one out of every six mammals known today.

Thomas was working at the Natural History Museum in London when the Tunney echidna specimen arrived, still misidentified as a short-beaked echidna. Thomas realized the specimen was actually a long-beaked echidna and removed the skull and some of the leg bones from the skin to prove that it was an Australian record of a long-beaked echidna, something just as unexpected then as it is now.

No one knows why Thomas did not publish that information. And the echidna went back into the drawer until Helgen came along 80 years later.

As Helgen became convinced that Tunney’s long-beaked echidna specimen indeed came from Australia, he confided in fellow scientist Mark Eldridge of the Australian Museum about the possibility. Eldridge replied, “You’re not the first person who’s told me that there might be long-beaked echidnas in the Kimberley.” (That’s the Kimberley region of northern Australia.) Scientist James Kohen, a co-author on Helgen’s ZooKeys paper, had been conducting fieldwork in the area in 2001 and spoke to an Aboriginal woman who told him how “her grandmothers used to hunt” large echidnas.

This is “the first evidence of the survival into modern times of any long-beaked echidna in Australia,” said Tim Flannery, professor at Macquarie University in Sydney. “This is a truly significant finding that should spark a re-evaluation of echidna identifications from across northern Australia.”

Helgen has “a small optimism” about finding a long-beaked echidna in the wild in Australia and hopes to undertake an expedition and to interview Aboriginal communities, with their intimate knowledge of the Australian bush.

Though the chances may be small, Helgen says, finding one in the wild “would be the beautiful end to the story.”

Meet Obama's Defense Secretary Nominee

President Obama nominated former Senator Chuck Hagel as the next U.S. secretary of defense. To those who haven't followed the Senate closely in the past decade, he's probably not a household name.

Hagel is a former GOP senator from Nebraska and Purple-Heart-decorated Vietnam veteran, but he wouldn't necessarily be a popular pick with Republicans in Congress.

At age 21, Hagel and his brother Tom became the next in the family to serve in the United States Army. They joined the masses of Americans fighting an unfamiliar enemy in Vietnam.

In his book, he describes finding himself "pinned down by Viet Cong rifle fire, badly burned, with my wounded brother in my arms."

"Mr. President, I'm grateful for this opportunity to serve our country again," Hagel said after Obama announced his nomination Monday.

In 1971, Hagel took his first job in politics as chief of staff to Congressman John Y. McCollister, a position he held for six years. After that, he moved to Washington for the first time, where he went on to work for a tire company's government affairs office, the 1982 World's Fair and in 1981, as Ronald Reagan's Deputy Administrator of the Veterans Administration.

He worked in the private sector for most of the 80s and 90s before his first election to the Senate in 1997.
Since the turn of the century, Hagel has followed a curvy path of political alliances that puts his endorsements all over the map. Hagel's record of picking politically unpopular positions could be a large part of why Obama is naming him for the job, as Slate's Fred Kaplan surmises the next Defense secretary will be faced with tough choices.

In 2000, he was one of few Republican senators to back Sen. John McCain over then-presidential-candidate George W. Bush.

After that election, Hagel fiercely criticized Bush for adding 30,000 surge troops to Iraq, in place of the bipartisan Iraq Study Group's proposal of a draw-down and regional diplomacy, which Hagel preferred. When Bush instead announced that more troops would go to Iraq, Hagel co-sponsored a nonbinding resolution to oppose it, along with then-Sen. Joe Biden, D-Del.

"The president says, 'I don't care.' He's not accountable anymore," Hagel told Esquire in June 2007. "He's not accountable anymore, which isn't totally true. You can impeach him, and before this is over, you might see calls for his impeachment. I don't know. It depends how this goes."

Hagel's fierce opposition to America's involvement in Iraq – he called it one of the five monumental blunders of history, on par with the Trojan War – will be of substantial importance as the Obama administration charts our course out of Afghanistan, deciding how to withdraw the last of the troops in 2014 and how much of a presence to leave behind.

Hagel's support for McCain, which was substantial in his competition against Bush, disappeared in the 2008 election. Hagel toured Iraq and Afghanistan with Obama during his first campaign for the presidency.

In October 2008, Hagel's wife, Lillibet, announced her support for the Obama team, after the Washington Post reported on her donations to his campaign. She donated again in 2012.

Before the 2008 election, Hagel wrote: "The next president of the United States will face one of the most difficult national security decisions of modern times: what to do about an Iran that may be at the threshold of acquiring nuclear weapons."

West vs Asia education rankings are misleading

Western schoolchildren are routinely outperformed by their Asian peers, but worrying about it is pointless

MATHEMATICS and science are as essential to modern economies as coal was to the industrial revolution. So when the results of international tests show Western schoolchildren lagging behind their peers in countries like Singapore and Japan, alarm bells start ringing.

The latest results to cause consternation are from a comparison of mathematical and scientific knowledge called TIMSS, or Trends in International Mathematics and Science Study. This is given every four years to 9-10-year-olds and 13-14-year-olds from more than 50 countries.

The results, released last month, show that students from the UK, US and Australia continue to perform disappointingly. In maths, for example, English, American and Australian 13-year-olds were outperformed by their peers in South Korea, Singapore, Chinese Taipei, Hong Kong, Japan and Russia. It was a similar story in science.

Cue much wailing and gnashing of teeth. US secretary of education Arne Duncan lamented that "a number of nations are out-educating us today... If we as a nation don't turn that around, those nations will soon be outcompeting us in a knowledge-based, global economy."

Australia's Education Standards Institute director Kevin Donnelly said the results proved that the country's education system had gone "pear-shaped".

However, there are reasons to think that such worries are misplaced.

First of all, although the results are not world-beating, they are far from terrible. All were above average, and better than many other developed nations. For the US at least, they continue a trend of long-term improvement. In the first international mathematics survey, conducted in 1964, the US finished second from bottom.

Second, the common-sense connection between test scores and future economic success doesn't necessarily hold up. For developed nations, there is scant evidence that TIMSS rankings correlate with measures of prosperity or future success. The same holds for a similar test, the Program for International Student Achievement (PISA).

In 2008, Christopher Tienken, then at Rutgers University in New Jersey, compared 1995 TIMSS scores with the 2006 Growth Competitiveness Index. This index was devised by the World Economic Forum to measure a nation's future economic health. Tienken found that for developed countries there was no statistically significant relationship (International Journal of Education Policy & Leadership, vol 3, no 4).

Tienken, now at Seton Hall University in South Orange, New Jersey, has since done a similar analysis of the 2003 PISA mathematics rankings and two measures of economic success: per-capita GDP in 2010, and the 2010-2011 Growth Competitiveness Index. The study, to be published in April, again found no statistically significant relationship.

These findings make TIMSS and PISA rankings seem irrelevant. But it could be worse than that. In many cases, high test scores correlate with economic failure.

Japanese students, for example, have always been near the top of the TIMSS. You might expect those high-flying students to be driving a high-flying economy. Yet the Japanese economy stagnated throughout the 1990s and 2000s.

There may be no causal connection, but the same negative correlation is seen elsewhere.

In 2007, Keith Baker of the US Department of Education made a rough comparison of long-term correlations between the 1964 mathematics scores and several measures of national success decades later.

Baker found negative relationships between mathematics rankings and numerous measures of prosperity and well-being: 2002 per-capita wealth, economic growth from 1992 to 2002 and the UN's Quality of Life Index. Countries scoring well on the tests were also less democratic. Baker concluded that league tables of international success are "worthless" (Phi Delta Kappan, vol 89, p 101).

A more recent analysis of 23 countries found a significant negative relationship between 2009 PISA scores and ranking on the Global Entrepreneurship Monitor's measure of perceived entrepreneurial capabilities. This counts the percentage of people in a country who feel confident that they could start a business.

With so many indicators showing a negative relationship, perhaps we need to reconsider how we interpret success - or failure - on international education scores. "If we believe that these tests actually tell us how well a kid or a country is doing, and then we hold people accountable for that, those people are going to focus on what's most likely to be tested, and they're going to cut out everything else," says Tienken.

This is especially relevant to the UK, where the education secretary Michael Gove has justified some of his controversial reforms by referring to the country's performance on the international educational stage.

We might instead consider that in a global economy, where the answers to almost any standard question are a few smartphone taps away, skills like creativity and initiative will be the true drivers of prosperity. None of these traits can be measured easily by tests. When testing consumes precious educational time, focus and money, they get squeezed out.

"Standardised tests reward the ability to find answers to pre-existing questions, but finding the question is more important," says Yong Zhao, an education researcher at the University of Oregon in Eugene who found the negative relationship between PISA scores and entrepreneurship.

We must, of course, continue to promote the importance of mathematics and science, but fixating on international tests as a way to achieve this could prove counterproductive.
