Shares in Australia's APN hit after directors quit

SYDNEY: Shares in Australian media firm APN News and Media plunged Tuesday after a walkout from board members over a capital raising dispute with major shareholder Ireland's Independent News and Media.

APN, owner of several Australian radio stations, billboard advertising assets, regional newspapers and some of New Zealand's top titles, said its chairman, CEO and three directors had resigned over a financial impasse.

"While the board agreed the company needed to reduce its debt, it was unable to agree on the methodology," APN said in a statement to the Australian Securities Exchange (ASX) after the close of trading on Monday.

"Independent News and Media and its major shareholder, together with (fund manager) Allan Gray -- representing approximately 51 percent of APN's shares -- have unequivocally indicated they are opposed to a capital raising at the present time."

Australian-listed shares in the media group slumped more than 13 percent at the open Tuesday. They were down 11.11 percent in neighbouring New Zealand.

The departures had been expected, with Irish tycoon Tony O'Reilly's INM requesting the removal of six directors, including the chairman and CEO, in favour of establishing a new board. A sixth board member is to retire as planned in April.

APN had intended to launch an Aus$150 million (US$155 million) rights issue in conjunction with its full-year earnings results later this week.

Those who resigned, including chairman Peter Hunt and CEO Brett Chenoweth, had advocated this approach as consistent with "a continued focus on repositioning the publishing business and potential asset sales."

The remaining board members believed that "consideration of an equity raising should be undertaken in a time frame that allowed other options to be pursued", APN said.

"The departing directors have a different view on gearing levels to the major shareholders, and in light of their opposing position it is not tenable for them to continue."

APN intends to announce its full-year results on Thursday as planned and has begun the process of recruiting replacements to the board.

O'Reilly failed in a 2007 takeover bid for APN after shareholders rejected his Aus$3 billion offer.

APN publishes 20 daily and more than 100 other newspapers across Australia and New Zealand, including the leading New Zealand Herald national broadsheet. It owns three of New Zealand's top five radio stations.

Google doodle does circles around Copernicus' birthday

Google is invoking the name Copernicus again, but this time it's not a joke.

The Web giant is celebrating the 540th birthday of the Renaissance mathematician and astronomer who changed the way people look at the universe with a doodle. Nicolaus Copernicus, who was born in 1473, is perhaps best known his heliocentric theory, which asserted that the sun, and not the Earth, was at the center of our universe.

The doodle is a representation of Copernicus' model for the solar system -- a golden sun encircled by six planets on stylized plane.

In an effort to improve the calendar, the Catholic church appealed to Copernicus in 1514. His heliocentric theory was central to "De Revolutionibus Orbium Coelestium" ("On the Revolutions of the Celestial Spheres"), which Copernicus finished in 1530. The theory challenged the long-held belief that the Earth was the stationary center of the universe with other planets, including the sun and moon, rotating around it.

"De Revolutionibus Orbium Coelestium" was published in 1543, shortly before Copernicus died on May 24 at age 70. (Legend has it the first copy was placed in his hands the day he died.) After centuries of searching, his grave was located in 2005, allowing his remains to be re-interred under a tombstone that bears a representation of Copernicus' model of the solar system.

In what is widely regarded as one of the greatest Internet hoaxes, Google borrowed the great astronomer's name in 2004 in a recruiting effort for the Copernicus Center -- its new "lunar hosting and research center." The Google Copernicus Hosting Environment and Experiment in Search Engineering (G.C.H.E.E.S.E.) was described as a research center for high-density high-delivery hosting (HiDeHiDeHo).

Confirmed: Dogs Sneak Food When People Aren't Looking

Many dog owners will swear their pups are up to something when out of view of watchful eyes. Shoes go missing, couches have mysterious teeth marks, and food disappears. They seem to disregard the word "no."

Now, a new study suggests dogs might understand people even better than we thought. (Related: "Animal Minds.")

The research shows that domestic dogs, when told not to snatch a piece of food, are more likely to disobey the command in a dark room than in a lit room.

This suggests that man's best friend is capable of understanding a human's point of view, said study leader Juliane Kaminski, a psychologist at the U.K.'s University of Portmouth.

"The one thing we can say is that dogs really have specialized skills in reading human communication," she said. "This is special in dogs." (Read "How to Build a Dog.")

Sneaky Canines

Kaminski and colleagues recruited 84 dogs, all of which were more than a year old, motivated by food, and comfortable with both strangers and dark rooms.

The team then set up experiments in which a person commanded a dog not to take a piece of food on the floor and repeated the commands in a room with different lighting scenarios ranging from fully lit to fully dark.

They found that the dogs were four times as likely to steal the food—and steal it more quickly—when the room was dark. (Take our dog quiz.)

"We were thinking what affected the dog was whether they saw the human, but seeing the human or not didn't affect the behavior," said Kaminski, whose study was published recently in the journal Animal Cognition.

Instead, she said, the dog's behavior depended on whether the food was in the light or not, suggesting that the dog made its decision based on whether the human could see them approaching the food.

"In a general sense, [Kaminski] and other researchers are interested in whether the dog has a theory of mind," said Alexandra Horowitz, head of the Dog Cognition Lab at Barnard University, who was not involved in the new study.

Something that all normal adult humans have, theory of mind is "an understanding that others have different perspective, knowledge, feelings than we do," said Horowitz, also the author of Inside of a Dog.

Smarter Than We Think

While research has previously been focused on our closer relatives—chimpanzees and bonobos—interest in dog cognition is increasing, thanks in part to owners wanting to know what their dogs are thinking. (Pictures: How smart are these animals?)

"The study of dog cognition suddenly began about 15 years ago," Horowitz said.

Part of the reason for that, said Brian Hare, director of the Duke Canine Cognition Lab and author of The Genius of Dogs, is that "science thought dogs were unremarkable."

But "dogs have a genius—years ago we didn't know what that was," said Hare, who was not involved in the new research. (See pictures of the the evolution of dogs, from wolf to woof.)

Many of the new dog studies are variations on research done with chimpanzees, bonobos, and even young children. Animal-cognition researchers are looking into dogs' ability to imitate, solve problems, or navigate social environments.

So just how much does your dog understand? It's much more than you—and science—probably thought.

Selectively bred as companions for thousands of years, dogs are especially attuned to human emotions—and, study leader Kaminski said, are better at reading human cues than even our closest mammalian relatives.

"There has been a physiological change in dogs because of domestication," Duke's Hare added. "Dogs want to bond with us in ways other species don't." (Related: "Dogs' Brains Reorganized by Breeding.")

While research reveals more and more insight into the minds of our furry best friends, Kaminski said, "We still don't know just how smart they are."

Nike, Oakley Distance Themselves from Pistorius

Corporate sponsors of Olympic "blade runner" Oscar Pistorius have begun to distance themselves from the sprinter, who is accused of murdering his model girlfriend, Reeva Steenkamp. Pistorius is back to court in South Africa Tuesday morning on murder charges.

Oakley, the eyewear manufacturer, and the sporting goods giant Nike announced today that they would no longer run ads featuring Pistorius, the South African double-amputee who gained worldwide fame for running on carbon-fiber blades.

"In light of the recent allegations, Oakley is suspending its contract with Oscar Pistorius, effective immediately. Our hearts are with the families during this difficult time and we'll continue to follow the developments in this tragic case," Oakley spokeswoman Cheri Quigley said in a statement released this afternoon.

Earlier in the day, Nike said it had "no plans" to use Pistorius in future ad campaigns, according to the Associated Press. Nike had already pulled an Internet ad showing Pistorius starting to sprint with the caption, "I am the bullet in the chamber."

The companies made their announcements shortly after Pistorius' own agent, Peet Van Zyl, said publicly that he expected the sponsors to stick with Pistorius through the legal process.

Pistorius will appear in court Tuesday morning for a bail hearing. His attorneys are expected to argue against the charge of premeditated murder.

His family has said the shooting was an accident.

The news comes as more details emerge about the incident on Thursday morning in which Pistorius allegedly shot and killed Steenkamp at his gated home in Pretoria, South Africa.

'Blade Runner' Murder Charges: Family Insist Accidental Shooting Watch Video

News reports in local papers have said that police are investigating whether Pistorius had an anger-management problem that led to the incident. They focused in on a bloodied cricket bat that may have been used when Steenkamp died.

A "shocked" teammate of Oscar Pistorius rebutted the rumors and speculation in South Africa that Pistorius had an anger problem.

Ofentse Mogawane, a sprinter for the South African Olympic team who ran the 400-meter relay with Pistorius in the London summer games last year, said Pistorius had always been genial to him and other people.

Mogawane said he would be in court Tuesday to support his friend.

"Basically, he was a very good guy to us, to the teammates and to most athletes," Mogawane said. "He was a really humble person and I wouldn't say a bad word about him. We never had any kind of clash, never any kind of fight or disagreement or arguing.

"The way Oscar's case was, it shocked me, shocked most of the people who know him. Tomorrow in court I am going to be there to support him. To hear what happened the night of the incident," he said.

"Sometimes when people are angry they cannot control their anger. Something must have happened."

Mogawane, 30, spoke in support of Pistorius after a report in South Africa's City Press newspaper that claimed police were looking into the possibility that a bloody cricket bat found in his bedroom was used before the shooting.

"The way the news has been running around in South Africa, that he is a short-tempered person, a person who has problems with anger management, they just want something to say," Mogawane said. "They don't know Oscar at all. They just want to get interviewed and take pictures. But truly speaking, it's just a lot of speculation."

Mogawane said he had seen Pistorius become angry before, but only in the same way as any other athlete or person.

But the City Press reported Sunday that police are investigating different scenarios involving the bat. Among them is the possibility that the flat-fronted bat was used in a violent argument before the shooting.

The paper also reported that Pistorius might have first shot Steenkamp in the bedroom, and that she possibly fled to the bathroom where she was shot three more times through the door.

When Pistorius' family arrived at the scene before paramedics, they saw him carrying Steenkamp down the stairs and performing mouth-to-mouth resuscitation on her, City Press reported.

Pistorius, who is nicknamed the "blade runner" because of the carbon-fiber blades on which he runs, has canceled all his upcoming racing appearances, his agent said Sunday night.

The decision was made to "allow Oscar to concentrate on the upcoming legal proceedings and to help and support all those involved as they try to come to terms with this very difficult and distressing situation," Van Zyl, of In Site Athlete Management, said in a statement.

Pistorius' father was quoted overnight in the South African paper The Sunday Times saying his countrymen are destroying a national icon.

Wiping out top predators messes up the climate

Wiping out top predators like lions, wolves and sharks is tragic, bad for ecosystems – and can make climate change worse. Mass extinctions of the big beasts of the jungles, grasslands and oceans could already be adding to greenhouse gases in the atmosphere.

Trisha Atwood of the University of British Columbia in Vancouver, Canada, studied the effect of removing predator fish from ponds and rivers in Canada and Costa Rica. Across a range of ecosystems, climates and predators, she found a consistent pattern: carbon dioxide emissions typically increased more than tenfold after the predators were removed.

"It looks like predators in many types of ecosystems – marine and terrestrial as well as freshwater – can play a very big role in global climate change," she told New Scientist.

The widespread and dramatic ecological impacts of the loss of top predators are well known. In the ensuing "trophic cascade", the vanished top predator's prey proliferate, which in turn puts pressure on the species that the prey eats, and so on down the food chain. In this way, changes at the top of a food chain destabilise the balance of populations right the way down.

But the geochemical impacts of trophic cascades, including any impact on emissions from ecosystems, are much less well known. Atwood's study of freshwater ecosystems showed how changes to species at the bottom of the food chain, such as photosynthesising algae, following the removal of a top predator dramatically increased the flow of CO₂ from the ecosystem to the atmosphere.

The effect will not always be to increase CO₂ emissions, however – sometimes the loss of top predators could decrease emissions, she says. "But we show that something so seemingly unrelated, like fishing all the trout from a pond or removing sharks from the ocean, could have big consequences for greenhouse-gas dynamics."

Help from kelp

Other recent studies have hinted at similar effects. Last October, Christopher Wilmers of the University of California, Santa Cruz, reported how the disappearance of sea otters is linked with increased CO₂ emissions from North American coastlines (Frontiers in Ecology and the Environment, doi.org/khz). With no otters eating them, sea urchins thrive and eat out kelp forests – often known as the "rainforests of the oceans" – resulting in major CO₂ releases.

Global climate models do not take such impacts into account yet. Atwood says they could be major, as freshwater emissions may be on a par with the influence of deforestation, which is thought responsible for around 15 per cent of human-caused CO₂ emissions.

Environmentalists will herald the findings as further evidence that it is vital to protect pristine habitats and the charismatic species at the top of their food chains. But there is a dark side. A recent study found that some island ecosystems around New Zealand store 40 per cent more carbon than others because of their top predators – invading rats that are wiping out seabird colonies. Rats, it seems, are good for the climate (Biology Letters, doi.org/bbmtw9).

Yen weakens in Asia after G20 talks

TOKYO: The yen weakened in Asia after G20 finance ministers pledged not to devalue their currencies and avoided targeting Tokyo over the recent plunge in the Japanese unit.

Japan's policy of monetary easing has led to sharp falls in the value of the yen, sparking fears of a global currency war in which rival nations would drive down their currencies to gain a trade advantage.

In the past few months, the dollar has gained about 17 percent on the yen while the euro has jumped about 25 percent against the Japanese currency, leading to charges that Tokyo is manipulating the unit.

But the Japanese government and the Bank of Japan (BoJ) have denied orchestrating a devaluation of the yen, which weakened Monday to 93.81 against the dollar from 93.53 in New York on Friday.

It also lost ground against the euro, which bought 125.26 yen from 124.97 yen in US trade.

The euro also bought $1.3332, compared to $1.3360 in New York on Friday.

The G20 statement issued on Saturday said: "We will refrain from competitive devaluation," adding "we will not target our exchange rates for competitive purposes".

The pledge echoed a recent statement by the G7 richest nations. Neither named Tokyo as a currency manipulator.

The yen's return to a weakening trend -- after rising before the G20 talks on started -- signalled that "exchange rate shifts arising from appropriate domestic monetary and fiscal policies will not be criticised or challenged", National Australia Bank said in a note.

"But direct reference to currencies as a policy objective will be," it added.

"We believe this means the yen is free to weaken, but Japanese officials must refrain from being seen to be goading the yen to weaker levels."

The BoJ, under pressure from Japan's new conservative government, last month unveiled a plan for unlimited monetary easing and an ambitious target for two percent inflation as part of a bid to beat lingering deflation.

A number of senior Japanese officials have speculated publicly about the yen being over-valued based on its previous stronger levels.

Japan's efforts sparked charges of manipulation, particularly in Europe, but others have played down currency war fears, with the International Monetary Fund calling such talk "overblown".

Markets are also watching for the nomination of a new BoJ governor as traders bet that Prime Minister Shinzo Abe will choose a candidate who shares his desire for policy easing.

Why Google's stores shouldn't look so much like Apple stores

Is this really different enough?

(Credit:
Crave CNET UK)

Some engineers have never dated a real person.

They've tried to, but it's hard for them to appreciate that real people don't necessarily use data to make decisions -- especially when it comes to love.

Perhaps their most embarrassing moments come when they try to mimic what non-engineers do in order to make themselves more attractive.

This mirrors some of the little issues that the Google brand has had over the years in becoming, well, human.

When you've spent you life believing that facts are everything, it's hard to imagine that people might prefer, oh, rounded corners or that ephemeral thing sometimes known as taste.

Google has made progress through some of its advertising. The "Jess Time" ad for Chrome was one of the very best tech ads of the 2012.

Yet when Google has wandered into retail, it has either believed that all you need is online or that an offline store ought to look rather like Apple's.

This is something against which Microsoft also struggles. It was almost comical when one Microsoft employee explained to me that its store looked -- at first glance -- a lot like the Apple store because the company used the same design firm.

This week, rumors surfaced that Google wants to make the next step in coming toward humanity by having its own shopping-mall retail presence.

The evidence so far from its pop-up stores -- as the picture above shows -- is that Google isn't thinking different. Or, at least, different enough.

If it fully intends to come out to the people -- to be itself-- then instead of having nice, clean retail staff in blue T-shirts (what brand does that remind you of?), it should embrace its true heart.

It should have real house-trained nerds, replete with bedhead and bad taste clothing, there for all to see. Yes, you could have nice, normal members of staff there to translate for them.

But the purpose of a retail store isn't merely to sell. It's to create street theater. Apple has its own version. Google must find its own too.

Instead of the now almost cliched clean lines and permanent white, it should make its stores look like excitable, sophisticated college playrooms, where books about dragons and vast Hulk hands are lying about and episodes of "Star Trek" and "Game of Thrones" are playing on huge screens.

More Technically Incorrect

It should expose itself fully as a brand that came out of nerdomania by parading its nerdomanic tendencies for all to see and making it lovable.

You might think this marginally insane. You might think that I am suffering from delusions of brandy.

Yet "The Big Bang Theory" has proved to be one of the most popular TV shows, not because the nerds are hidden away, but because they are in full view, with a beautiful counterpoint in a real person called Penny.

Imagine taking your kids, your lover, or your granny into a Google store and having them actually enjoy learning something about, say, comic books or Hermann von Helmholtz.

Imagine walking in and one of the Google nerds has dressed as The Flash, Batman, or Wonder Woman for the day, yet still finds a way to sell you a fascinating
Nexus 7.

In fact, wouldn't it be an excellent human resources idea, as well as a stimulus to make more uplifting products, if every Google engineer had to spend a certain period working in a Google retail store?

Mountain View should surely mine the more lofty, fantastic elements of its reality in order to create something unique and dramatic.

Otherwise, its stores might simply be accused of being Apple rip-offs.

And you know where that will ultimately end up. Yes, in front of Judge Lucy Koh.

Meet the Meteorite Hunter

Michael Farmer is one of the world's only full-time meteorite hunters. Since the 1990s, the 40-year-old Tucson, Arizona, resident has been scouring the world for pieces of interstellar rock, racing to be the first one on the scene and selling his finds to museums and private collectors. On Friday, as Russians reportedly scrambled to collect fragments from a passing meteorite that injured hundreds, Farmer spoke with National Geographic about his unusual line of work.

Why are so many people in Russia busy gathering up meteorite fragments?

It's a historic event. This will be talked about forever. Everyone wants to have a little piece of it. And scientifically, we want to study it. We want to know what's out there, and we want to know how big it is, and we want to know what damage it can cause. The preliminary data from NASA's Jet Propulsion Laboratory says about 7,000 tons landed.

How many meteorite fragments are known to be on Earth?

There are a couple of hundred thousand known meteorites. Of course, there's millions and millions on the planet; we just have to find them. Most of the Earth is inhospitable—heavy forest, jungle, ocean. Meteorites that fall in the ocean are just gone, disappeared to the bottom.

How many other full-time meteorite hunters are there?

Dedicated, serious meteorite hunters? There are maybe 20 of us. If you add in the part-timers who go somewhere whenever [an impact is] close to them, then you might approach a hundred.

How did you become a meteorite hunter?

Here in Tucson right now we have the world's biggest mineral show going on. I bought a meteorite at this very same show 20 years ago, and I was absolutely obsessed and hooked. Since then I've been around the world more times than I can count—four million miles on American Airlines alone.

How many countries have you been to?

About 70 countries, by my last count. About 50, 59 trips to Africa—a lot of work in Africa. The Sahara and other deserts there make meteorites easier to find than on other terrains, and also keep them well preserved.

What are the challenges you face when you're on a hunt?

Well, you're usually going into a kind of chaotic scene where nobody really knows much. In Africa and other places I go [the locals] don't usually understand what's happening, and most of the time they don't care. They're more concerned with eating that day. But the instant some guy shows up and says, "I'll pay you to find this rock," the whole village empties—and then lots of rocks show up.

It can be dangerous work. I've been robbed, put into prison. For example, I was in prison two years ago in the Middle East, in Oman—actually sentenced, convicted, and put in prison for three months for "illegal mining activity." Not a very nice time. And the same year, 2011, in the fall I went to Kenya three times, after a major meteorite fell. On the third trip over I had a robbery where they ambushed us and almost murdered me. I was down on my knees, with a bag over my head and a machete on my throat and a gun at my head, being beaten. Luckily they decided to just take everything and leave instead of killing us. It's a dangerous line of work because it involves money, and people want that money.

What's the most valuable meteorite you've found?

Well, I've found three separate moon rocks in the Middle East. [Moon rocks are considered a type of meteorite that came loose from the lunar surface and fell to Earth.] And one of them I sold for $100,000 a week later. It was just a small piece—the size of a walnut. But the best meteorite I found was with my three partners up in Canada. It was actually discovered in 1931, but we went back to the location and discovered 53 kilograms [117 pounds] more. It's an extremely rare type of meteorite called a pallasite, and it's about 4.5 billion years old. We sold it to the Canadian government for just under a million dollars. Now it's in the Royal Ontario Museum, in Toronto, and it's considered a national treasure.

Where else do you sell your wares?

Well, I do shows around the world, in France, Germany, Japan. I go to expos, like this one here in Tucson, which is the biggest mineral show in the world and lasts for three weeks. And museums are always calling me.

Related: Archival Photos of Meteorite Recovery

It's a small market. It's not like I need a shop or anything. People call me or email me or go to my website and check it out. The market these days is so ravenous for anything new that when I get a new meteorite, it's usually sold in hours. I don't even have to work anymore. I just make phone calls to a few people, and it's all gone.

Where do you store your collection?

I have multiple storage sites—never put all your eggs in one basket. And I have lots of bulk material. Sometimes I buy this stuff by the ton, and it goes into storage and I sell it off one piece at a time.

What's the verification process like?

Any meteorite, anything that we want to have an official name, has to go to a laboratory, where it gets sectioned and studied by scientists. For example, I'd guess this meteorite in Russia yesterday will be in a lab in Moscow, being researched within hours.

Related: History's Big Meteorite Crashes

In the collector market, we work collaboratively with the scientists. I supply them with rocks, and they supply me with data, both of which I need to make money. People want to know what something is before they buy it.

Are there legal or ethical implications to meteorite hunting?

There always are. Certain countries have passed laws. But when I was arrested in Oman, they actually had no law—they were just very upset that we were taking lots of meteorites. The only law they could charge us with was illegal mining operations—basically running a company in the country without government licensing. But I won on appeal because we had no mining equipment. We were picking up rocks off the surface of the desert. And a judge said, "If a child could do it, then it's not mining." And I was immediately released and sent home.

But there's always friction between the collecting market and the scientific market. There are scientists out there who believe that no meteorite should be in private hands. Well, I tell you, I've been on hunts all over the world and I've only run into scientists a couple of times. They don't have the time or money to do it. So if it wasn't for us, 99 percent of these meteorites would be lost to science.

What about this meteorite strike—do you think scientists will go to Russia?

I guarantee there'll be scientists from everywhere in the world going to this one.

Are you catching the next flight to Moscow?

Well, of course as a meteorite dealer, I want to own this. I woke up this morning to a hundred e-mails from people begging me to get on a plane and go get it so they can buy a piece.

But I'm probably not going. Getting into Russia can be complicated. I'll just buy some from the Russians when it comes out.

Of course, if this had happened in China or somewhere in Africa, I'd be packing my bags right now and getting on a plane, figuring it all out when I get there.

Pistorius Case: Agent Cancels All Future Races

Oscar Pistorius won't run in any of the future races that the athlete was contracted to compete in, but the Paraylmpic gold medalist's sponsors are still supportive as he faces a murder charge, his agent said today.

The decision to cancel Pistorius' scheduled appearances was made to "allow Oscar to concentrate on the upcoming legal proceedings and to help and support all those involved as they try to come to terms with this very difficult and distressing situation," Peet Van Zyl of In Site Athlete Management said in a statement.

"I have decided that following these tragic events that we have no option but to cancel all future races that Oscar Pistorius had been contracted to compete in," Van Zyl said.

Pistorius was slated to compete in races in Australia and Brazil, as well as at the Drake Relays in Iowa and the Manchester City Games in the U.K.

Van Zyl also said that Pistorius' sponsors and partners are supportive.

"I can confirm that at this point in time, all parties are supportive and their contractual commitments are maintained. They have said they are happy to let the legal process takes its course before making any change in their position," Van Zyl said in the statement.

However, M-Net movies, a subscription-funded South African television channel has pulled their ad campaign featuring Pistorius, tweeting, "Out of respect & sympathy to the bereaved, M-Net will be pulling its entire Oscar campaign featuring Oscar Pistorius with immediate effect."

The agent's announcement comes as family and friends rallied to Pistorius' defense -- saying they believe the Paralympic gold medalist's story that he shot his model girlfriend Reeva Steenkamp by accident after he mistook her for an intruder.

"When you are a sportsman, you act even more on instinct ... it's instinct -- things happen and that's what you do," Pistorius' father Henke Pistorius, 59, told The Telegraph.

The 26-year-old athlete, known as the "Blade Runner" because of the carbon-fiber blades he runs on, was charged Friday with premeditated murder.

If convicted, Pistorius could face at least 25 years in jail.

"All of us saw at firsthand how close [Steenkamp] had become to Oscar during that time and how happy they were. They had plans together and Oscar was happier in his private life than he had been for a long time," Pistorius' uncle Arnold Pistorius said on Saturday.

According to South African newspaper Beeld, Steenkamp was killed nearly two hours after police were called to Pistorius' home to respond to reports of an argument at the complex.

Police said they have responded to disputes at the sprinter's residence before, but did not say whether Steenkamp was involved.

The athlete's best friend said Pistorius called him after the shooting to say "there has been a terrible accident, I shot Reeva," Justin Divaris told the Sunday People.

While his family insists he is not a murderer, prosecutors disagree.

Police sources told local media that Steenkamp was shot through the bathroom door where she may have been trying to hide to save herself.

Reeva Steenkamp

A memorial service for Steenkamp will be held in Port Elizabeth on Tuesday evening, SABC reported. Her body will be flown back for the service before being cremated, her family said.

"Her future has been cut short ... I dare say she's with the angels," said Mike Steenkamp, Reeva Steenkamp's uncle.

The South African reality show Steenkamp competed in premiered Saturday night on SABC as planned and included a special tribute to the slain law school graduate whose modeling career was starting to take off.

False memories prime immune system for future attacks

IN A police line-up, a falsely remembered face is a big problem. But for the body's police force – the immune system – false memories could be a crucial weapon.

When a new bacterium or virus invades the body, the immune system mounts an attack by sending in white blood cells called T-cells that are tailored to the molecular structure of that invader. Defeating the infection can take several weeks. However, once victorious, some T-cells stick around, turning into memory cells that remember the invader, reducing the time taken to kill it the next time it turns up.

Conventional thinking has it that memory cells for a particular microbe only form in response to an infection. "The dogma is that you need to be exposed," says Mark Davis of Stanford University in California, but now he and his colleagues have shown that this is not always the case.

The team took 26 samples from the Stanford Blood Center. All 26 people had been screened for diseases and had never been infected with HIV, herpes simplex virus or cytomegalovirus. Despite this, Davis's team found that all the samples contained T-cells tailored to these viruses, and an average of 50 per cent of these cells were memory cells.

The idea that T-cells don't need to be exposed to the pathogen "is paradigm shifting," says Philip Ashton-Rickardt of Imperial College London, who was not involved in the study. "Not only do they have capacity to remember, they seem to have seen a virus when they haven't."

So how are these false memories created? To a T-cell, each virus is "just a collection of peptides", says Davis. And so different microbes could have structures that are similar enough to confuse the T-cells.

To test this idea, the researchers vaccinated two people with an H1N1 strain of influenza and found that this also stimulated the T-cells to react to two bacteria with a similar peptide structure. Exposing the samples from the blood bank to peptide sequences from certain gut and soil bacteria and a species of ocean algae resulted in an immune response to HIV (Immunology, doi.org/kgg).

The finding could explain why vaccinating children against measles seems to improve mortality rates from other diseases. It also raises the possibility of creating a database of cross-reactive microbes to find new vaccination strategies. "We need to start exploring case by case," says Davis.

"You could find innocuous pathogens that are good at vaccinating against nasty ones," says Ashton-Rickardt. The idea of cross-reactivity is as old as immunology, he says. But he is excited about the potential for finding unexpected correlations. "Who could have predicted that HIV was related to an ocean algae?" he says. "No one's going to make that up!"
