If governments could pass a simple law that would save the lives of millions of infants, they’d do it, right? And if a policy or constitution could transform the lives of women by sparing them the poor health or despair that they inevitably pass on to their children through sickness, disability, and even death, surely they would get working?


But no.


A new book, the first of its kind, together with the extensive report underpinning it, shows just how far the world has to go - even (or perhaps, especially) rich countries like the US.


Children’s Chances: How countries can move from surviving to thriving by Jody Heymann with Kristen McNeill was launched (with the accompanying report) in London last week. It aims to provide an armoury of deeply disturbing data with which to hold to account the world’s passive politicians.





It is a culmination of years of work led by Heymann, who is director of the World Policy Analysis Center and dean of the University of California, Los Angeles, Fielding School of Public Health.


She and her colleagues have sifted through (quite literally sometimes) boxes piled with paper and reams of information from organisations like UNESCO to provide the first global comparison of laws and public policies in 191 countries covering poverty, discrimination, education, health, child labour, child marriage and parental care options.


Laws really matter, found Heymann and her colleagues. Laws covering what look to be family or cultural decisions such as early child marriage or education are important because these issues determine whether a child survives or thrives.


When girls marry young, for example, they tend to drop out of school earlier and have poorer health, and, in turn, their children have poorer health.


At the book’s launch at the Royal Society in London Heymann said that sometimes just having a law can help: “What surprised me is that many people had said, 'What if policies are not fully implemented?' In fact many of these policies are so powerful that it is enough [to make a difference].”


The book, report and website aim to make the crucial information Heymann and her colleagues have gathered accessible to ordinary citizens, non-governmental organisations and policy-makers.


It’s readable, and given the Herculean task the authors had bringing it all together, makes clear sense of what they found with online maps providing a wealth of revealing information never before available, at a keystroke.


But I can’t help feeling that they are missing a trick. The tone of the book may be assertive, but it is not as forceful as its material - just too polite.


Why beat about the bush when children’s lives, health and future are at risk? Name and shame, I say. This book has the moral high ground, and scientific rigour, to do so. And it should.


At the launch, the US was rightly described as a “laggard”, but it is only by trawling through the maps that it becomes clear just how far behind it is for a rich nation.


What, for example, does the US have in common with Papua New Guinea, Liberia and Tonga?


These are three of only eight countries in the world with no guaranteed paid maternity leave. As for paternity leave, paid parental leave for sick children - forget it.


And there isn’t even protection against early child marriage. The US is right up there with Sudan and Iran, with no legal minimum age for marriage for girls or boys.


This was shocking, but the authors don’t go into surprises like this. Surely we should be told what the lack of such a law does to a developed nation like the US? Does anyone actually get married very young? If so, how young, and how common is it?


But we do know that lack of maternity leave makes a huge difference. Globally every 10-week increase in paid maternity is associated with a 10 per cent drop of newborn deaths, infant deaths and under-5 mortality rates. Staggering.


The reasons are simple. Off work, mothers are more likely to breastfeed and take their babies to be vaccinated.


Even in the US, infant mortality rates are not good for a developed nation. And recent studies show the country’s health generally is not as robust as it could be.


There are plenty of other surprises.


What does Laos do for its children that the UK doesn’t? Astonishingly, it is one of five countries in the world with father-specific paid paternity leave of over four weeks. The others are Iceland, Norway, Slovenia and Sweden.


Luxury? No. Paternity leave matters and when it's specifically allocated to men, dads are more likely to take it. Studies show that fathers who take paternity leave when it is available are much more involved with care of their children, even after a pre-existing commitment to mother and child is controlled for.


And where fathers are involved, new mothers are less likely to get depressed - and maternal depression has strong knock-on effects on children.


Then again, what makes one of the poorest African nations a better place to be a child than its neighbours? Madagascar has policies for children and families that are more progressive than many western nations, and this has paid off because its infant and child mortality rates are among the lowest in sub-Saharan Africa.


Sadly, the most powerful of the emerging economies - India and China - fare worse than many very poor countries in terms of children’s chances and healthcare.


The authors want this to be a call for action. But they need to shout louder. While they do quote the numbers of countries opting out of child-friendly policies or laws in their report, they should name the countries - and give them a report card. And likewise hail the countries (especially the poor ones) doing right by their kids.


The book does try quite hard in some ways, detailing heart-rending case studies of kids so hungry that they fall asleep at school, 9-year-olds rising at 4 am to help their parents set up street vegetable stalls before going to school, or parents who can’t take seriously ill kids to the doctor because they risk losing their jobs if they take time off…


The good news is that governments can move mountains if they find the will: saving the lives of millions of children worldwide is surely easy compared with finding a cure for AIDS or cancer?


Heymann and colleagues should be commended for their meticulous and arduous work. Let’s hope citizens, NGOs and movers and shakers pick up this report and wield it forcefully in the faces of governments.

India sets rules for new bank permits in rural push






MUMBAI : India on Friday unveiled rules for issuing new bank licences in a push to expand financial services into the country's rural hinterland where hundreds of thousands of villages have no banking outlets.

Ninety percent of India's 600,000 villages do not have banking facilities, the Reserve Bank of India says, while fewer than half of the country's 1.2 billion people have a bank account.

Private companies, public-sector groups and non-banking financial firms will be eligible to apply for licences for new banks by setting up financial holding companies, the central bank said in a statement.

Groups seeking to set up a bank "should have a past record of sound credentials and integrity, be financially sound with a successful track record of 10 years", the Reserve Bank said.

The minimum capital needed to set up a bank will five billion rupees (US$91 million).

Also, the new banks will have to open at least a quarter of their branches in rural areas with no such facilities, and foreign shareholdings in any new bank should not exceed 49 percent in the first five years.

The need to set up more banks, especially in rural areas, has become increasingly urgent as the government seeks to pay cash directly to India's poor to ensure more efficient distribution.

Indian conglomerates like the Tata Group and the Anil Ambani Reliance group, which already own financial businesses, have voiced interest in setting up banks.

The Reserve Bank is seeking to follow a path of "financial inclusion", embracing swathes of rural India which have little access to banking services, the bank's governor Duvvuri Subbarao said.

No new Indian bank has been set up since the private Yes Bank in 2004. Yes Bank now is a leading industry player.

India currently has just 26 state-run, 20 private and 40 foreign banks.

Another 2,200 rural and co-operative banks cover other parts of the country.

The Finance Ministry said it hopes the Reserve Bank will be able to start issuing licences for new banks by the end of the next financial year, which runs to March 2014.

"With all going well, with all clearances, by end of the (next) financial year we will see some success," Financial Services Secretary Rajiv Takru told reporters in New Delhi.

iPhone Mini launch this summer makes sense, analyst says

(Credit:
CNET)

A low-priced iPhone makes a lot of sense, Morgan Stanley says, and it even could hit the market this summer. Katy Huberty, an analyst with the banking firm, noted that after her meetings with Apple Chief Financial Officer Peter Oppenheimer, she's convinced that innovation remains a top priority for the Cupertino, Calif., electronics giant. She also believes that Apple will increase cash return to shareholders and expand carriers, distribution, and possibly price points to drive iPhone growth.

She noted that a lower priced iPhone makes sense for several reasons:

  1. "iPad Mini is expanding Apple's customer base with 50 [percent] of purchases in China/Brazil representing new customers to the ecosystem."

  2. "Chinese consumers show a desire to purchase the latest version of iPhone (instead of discounted older generations)."

  3. "iPhone 4 demand surprised to the upside in the December quarter."

Huberty added that while an iPhone Mini would have lower gross margins and cannibalize other iPhone sales, it would boost revenue and profits.

She noted that new iPhones, including a lower-priced iPhone for emerging markets, could launch this summer, while the
iPad will likely be refreshed by mid-year. Many reports in recent weeks have pegged an iPhone Mini launch to the summer timeframe.

Huberty also expects new carrier partnerships including NTT Docomo, T-Mobile, and China Mobile in the second half of the year or 2014.

Speculation has been building that Apple will soon release a cheaper iPhone. While it continues to sell many models of its newest iPhone, many customers have been opting for the older, discounted generations. And as smartphones sales growth slows in the U.S. and other mature markets (because almost everyone has a phone), emerging markets will become even more key to future sales. A lower priced phone would help Apple sell more devices in places like China, where few people can afford to buy its priciest gadgets.

Oscar Pistorius Granted Bail in Murder Case












Oscar Pistorius was granted bail today in a South African court, meaning he can be released from jail for the six to eight months before his trial for the allegedly premeditated killing of his girlfriend Reeva Steenkamp.


Magistrate Desmond Nair, in reading his lengthy decision, said, "The issue before me is whether this accused, being who is and the assets he has [here], would seek to duck and dive all over the world."
His conclusion:
"I cannot find that he is a flight risk."


Nair said, "The accused has made a case to be released on bail."

The judge also said he had to weigh whether Pistorius would be a danger to others. He noted that Pistorius has been accused of using foul language against people in arguments and once threatened to break someone's legs, but he said that was different from someone with an arrest record of violence.


"I appreciate that a person is dead, but I don't think that is enough," he said.


Nair also said he could not be influenced by the public's "shock and outrage" if Pistorius is released.


A member of Pistorius' defense team told ABC News, "he is going to be released today."


Despite the ruling, prosecutors displayed confidence, with one of them emerging from the courthouse today to say, "We still believe we have the evidence to convict Oscar Pistorius."


The court set bail at about $113,000 (1 million rand) and June 4 as the date for Pistorius' next court appearance.


The other bail conditions are: Pistorius cannot leave the country; he must hand over his passports; he cannot return to his home as long as it's an active crime scene; he needs permission to leave the Pretoria area; he must visit a police station on a daily basis and be available to a probation officer at all times via cellphone; he is not allowed any communication with prosecution witnesses; he cannot drink alcohol; and he must relinquish his firearms.


"Do you understand?" the magistrate asked him.


"Yes, sir," Pistorius replied.

'Blade Runner' Shocker: Lead Detective Replaced Watch Video





Speaking for the family, Arnold Pistorius, the Olympian's uncle, said, "Although we are obviously relieved that Oscar has been granted bail, this is still a very sad time for the family of Reeva and for us.


"We are grateful that the Magistrate recognized the validity and strength of our application. As the family, we are convinced that Oscar's version of what happened on that terrible night will prove to be true."


The judge's ruling came on the fourth and final day of the bail hearing for Pistorius, the Olympian accused of murdering his girlfriend on Valentine's Day.


Pistorius, who gained global acclaim for racing at the 2012 London Olympics, shot his model-girlfriend through a closed bathroom. He says he killed Reeva Steenkamp accidentally, but prosecutors alleged that he took a moment to put on his prosthetic legs, indicating that he thought out and planned to kill Steenkamp when he shot her three times through the bathroom door.


Pistorius sobbed today in court. Barry Roux, his defense attorney, said the prosecution misinterpreted the assigning of intent, meaning that the runner's intent to shoot at a supposed intruder in his home cannot be transferred to someone else who was shot -- in this case, Steenkamp.


"He did not want to kill Reeva," Roux told the court.


FULL COVERAGE: Oscar Pistorius Case


When Magistrate Nair, who overheard the bail hearing, asked Roux what the charges should be if Pistorius intended to kill an intruder, the defense attorney responded that he should be charged with culpable homicide.


Culpable homicide is defined in South Africa as "the unlawful negligent killing of a human being."


Roux also made light of the prosecution's argument that Pistorius is a flight risk, saying that every time the double-amputee goes through airport security, it causes a commotion. He said that Pistorius' legs need constant maintenance and he needs medical attention for his stumps.


The prosecution argued today that the onus was on Pistorius to provide his version of events, and his version was improbable.


Prosecutor Gerrie Nel also spoke of Pistorius' fame and his disability, even relating him to Wikipedia founder Julian Assange, who is now confined to Ecuador's London Embassy, where he has been granted political asylum.
"[Assange's] facial features are as well known as Mr. Pistorius' prostheses," Nel said.


Nel argued that Pistorius' prostheses do not set him apart, stating that it's no different to any other feature, and the court cannot be seen to treat people with disabilities accused of a crime, or famous people accused of crime, any differently.


Pistorius has said that in the early hours of Feb. 14 he was closing his balcony doors when he heard a noise from the bathroom. Fearing an intruder, and without his prosthetic legs on, he grabbed a gun from under his bed and fired through the closed bathroom door, he told the court.


But prosecutors say that's implausible, that the gun's holster was found under the side of the bed where Steenkamp slept, and that Pistorius would have seen she wasn't there. Prosecutors also say the angle at which the shots were fired shows Pistorius was already wearing his prosthetics when he fired.

First space tourist plans independent Mars mission



Jacob Aron, reporter

An organisation led by Dennis Tito, the first ever space tourist, has announced its intention to launch a mission to Mars in 2018 - though just who or what will be on board remains to be seen.





Tito paid $20 million to be the first paying guest of the International Space Station in 2001, marking the start of the space tourism industry. Now he has formed the Inspiration Mars Foundation, which plans to launch "an historic journey to Mars and back in 501 days", according to an announcement in advance of a press conference next Wednesday.


The announcement does not give many more details of the mission, but other speakers lined up for the press conference give some clues. Jonathan Clark of the National Space Biomedical Research Institute in Houston, Texas, a former NASA crew surgeon and recent advisor on Felix Baumgartner's supersonic skydive from near the edge of space, will probably speak about the health risks of a long-term space mission, which hints at the possibility of a crewed mission.


Also speaking are Jane Poynter and Taber MacCallum of Paragon Space Development, a company with expertise in life support in extreme environments. The pair were both members of the Biosphere 2 mission, a controversial attempt at simulating a space colony two decades ago, and have previously proposed landing a greenhouse on the moon to grow flowers there.


Speculation ahead of the announcement is rife. Wired reckons the mission will aim to be crewed. NBC
is more cautious, suggesting that the plan might be to put plants or animals on board
instead, as pulling a crewed mission together in five years would be
expensive and risky. The 2018 date is particularly favourable because the
orbits of Earth and
Mars will be closely aligned, but NASA recently scrubbed a launch that
year in favour of a 2020 sequel to its successful Curiosity rover. Bottom line: it's hard to get to Mars in a hurry.


We
also don't know whether the mission is meant to land on Mars or
merely orbit the planet. Space Adventures, which booked Tito's ISS
trip, has been selling moon fly-bys since 2005, though none has taken place so far. But even an uncrewed return mission to the surface of the Red Planet would make history if it brought Mars rocks back to Earth.


Also
to be announced is just how Tito plans to get to Mars. The obvious
answer is to use Space X's Red Dragon craft, a planned variant of the
Dragon capsule that has already serviced the ISS. Space X founder Elon Musk has promised to deliver humans to Mars within a decade, so five years might be slightly short notice. We'll find out more on 27 February.

Cycling: Giro d'Italia to start in Belfast next year






BELFAST, United Kingdom: Another of cycling's biggest races will start in Britain next year after organisers announced on Thursday that the Giro d'Italia will be flagged off in Northern Ireland.

The 2014 edition of one of the sport's three Grand Tour races will begin in Belfast on May 10, kicking off three days of action that will also include a stage finishing in Dublin, capital of the Republic of Ireland.

Michele Acquarone, head of the Giro and managing director of Italian race organiser RCS Sport, said: "Belfast will provide spectacular backdrops for the 2014 Grand Partenza (Big Start) and will add something very special into the history of this great cycling event."

Northern Ireland tourism minister Arlene Foster added: "Plans are already in motion to make the occasion a fabulous celebration worthy of Italian cycling traditions and the maglia rosa (pink jersey) itself."

The news comes after it was annonced in December that the first three stages of the 2014 Tour de France will be in England, with two in the northern county of Yorkshire and the third finishing in London.

Traditionally, Italy's Giro - in common with the Tour de France - never strayed beyond its own national borders.

But recently both races have opted for starts abroad, with the 104-year-old Giro launched from outside Italy every two years, latterly in Denmark in 2012.

Cycling star Bradley Wiggins, who last year became the first British winner of the Tour de France and also won Olympic time-trial gold, confirmed the Giro's prestige by declaring that he wants to win this year's edition above defending his Tour title.

Ireland cycling great Stephen Roche, who won the Giro back in 1987, was present for Thursday's announcement at the Titanic Belfast visitors' centre.

"The Giro is maybe distinctive in that it is probably the second biggest event for me, in my opinion (after the Tour de France)," he said.

"When you consider the passion these people have, the passion these people have shown to us this morning, it is duplicated throughout the whole Italian nation."

He recalled that in 1987 the crowds were warm and enthusiastic.

"When you see all the people on the roadsides of Italy, the enthusiasm of poor and rich, they all come together for this event," Roche said, adding that the support he received during the Giro spurred him to success in the Tour de France.

"It gave me a lot of extra confidence for the Tour," he said. "Then you are surfing the wave and you become, I would not say unbeatable, but the fact that you have one big win under your belt, it makes the rest much more possible."

Finer details about PlayStation 4's DualShock 4 controller, Eye camera





The new DualShock 4 controller for the PlayStation 4 utilizes Micro-USB instead of Mini-USB.

Sony Computer Entertainment)


As Sony explained the hardware and software in the upcoming PlayStation 4 yesterday, two very important input devices -- the DualShock 4 controller and PlayStation 4 Eye camera -- also debuted. But Sony wasn't completely up front about how it will all work.


Fortunately, an official Sony press release sheds further light on the two crucial pieces of PS4 hardware.



The Bluetooth 2.1+EDR-equipped Dualshock 4 controller follows the tried-and-true design used in previous generations of PlayStation controller design, but this go around comes with more new features than ever before. Oh, and it rumbles a little harder, too.





What do you think about the new DualShock controller? Sound off in the comments below.

Sony Computer Entertainment)



The DualShock 4's new light bar contains three color LEDs and corresponds with the PlayStation Move motion capture interface. The LED array can change colors to match the color of a character in a video game, or alert a player to an important situation -- for example, a flashing pattern when you near death.


Say goodbye to the start and select buttons: those old standards now live within the options button placed near the top. Nearby, a share button gives gamers the ability to stream live gameplay to UStream, upload recorded gameplay videos to Facebook, and other social options. Pictures provided by Sony indicate that the DS4 may sport a rubber (or etched plastic) rear for enhanced gripping and less fumbles.





A solid look at the DS4 for the PS4.

Similar to the rear touchpad on the PlayStation Vita, the DS4 introduces a two-point capacitive touch pad (with the ability to click) above the analog sticks, which opens the door for some unique gaming interactions. The sensitive six-axis accelerometer/gyroscope makes a return. Sound becomes front and center in this new design, as Sony integrated a small mono speaker as well as a stereo jack that enables a gamer to speak in a headset and simultaneously hear game audio emanating from the controller.


Other DualShock 4 features include improved analog sticks/trigger buttons, and the option to charge the controller even when the console isn't powered on. For those curious about finer details: the DS4 weighs about 0.6 ounces more than the DualShock 3, and the DS4 is only just a few centimeters different in width, height, and depth.





Meet the PlayStation 4 Eye camera (positioned on top of a TV).

As for the PlayStation 4 Eye, well, it's a much more dramatic shift compared with the predecessor. The new bar-shaped Eye, of course, works with PlayStation Move (and DualShock 4) motion control, and looks on paper as a more suitable contender against a future version of Microsoft's Kinect. Why? Well, the Eye packs dual cameras that can individually capture 1280x800 pixel RAW/YUV video at 30fps (and 640x480 at 120fps or 320x192 at 240fps) each -- these figures stand way above the existing single-lens Eye and its outdated 640x480 video capture capabilities.


Those the dual-lens Eye can observe an 85-degree diagonal viewing angle (up from the previous 75 degrees) and should have little issue perceiving depth and the location of multiple players in a living room. For audio capture, the Eye can hear a great deal due to its four integrated microphones, which could make misunderstood voice commands a thing of the past. Gamers can also log in to the PS4 with the Eye's facial-recognition software.


Sony didn't announce availability or pricing for either accessory during the PS4 reveal, but stay tuned to CNET and we'll have you covered as things unfold.





The PS4 Eye can tilt upward or downward.

NASA's Mars Rover Makes Successful First Drill


For the first time ever, people have drilled into a rock on Mars, collecting the powdered remains from the hole for analysis.

Images sent back from NASA's Mars rover Curiosity on Wednesday confirmed that the precious sample is being held by the rover's scoop, and will soon be delivered to two miniature chemical labs to undergo an unprecedented analysis. (Related: "Mars Rover Curiosity Completes First Full Drill.")

To the delight of the scientists, the rock powder has come up gray and not the ubiquitous red of the dust that covers the planet. The gray rock, they believe, holds a lot of potential to glean information about conditions on an early Mars. (See more Mars pictures.)

"We're drilling into rock that's a time capsule, rocks that are potentially ancient," said sampling-system scientist Joel Hurowitz during a teleconference from NASA's Jet Propulsion Laboratory in California.

A Place to Drill

The site features flat bedrock, often segmented into squares, with soil between the sections and many round gray nodules and white mineral veins.

Hurowitz said that the team did not attempt to drill into the minerals or the gray balls, but the nodules are so common that they likely hit some as they drilled down 2.5 inches (6.3 centimeters).

In keeping with the hypothesis that the area was once under water, Hurowitz said the sample "has the potential of telling us about multiple interactions of water and rock."

The drill, located at the end of a seven-foot (two-meter) arm, requires precision maneuvering in its placement and movement, and so its successful initial use was an exciting and welcome relief. The rover has been on Mars since August, and it took six months to find the right spot for that first drill. (Watch video of the Mars rover Curiosity.)

The flat drilling area is in the lower section of Yellowknife Bay, which Curiosity has been exploring for more than a month. What was previously identified by Curiosity scientists as the dry bed of a once-flowing river or stream appears to fan out into the Yellowknife area.

The bedrock of the site—named after deceased Curiosity deputy project manager John Klein—is believed to be siltstone or mudstone. Scientists said the veins of white minerals are probably calcium sulfate or gypsum, but the grey nodules remain something of a mystery.

Triumph

To the team that designed and operates the drill, the results were a triumph, as great as the much-heralded landing of Curiosity on the red planet. With more than a hundred maneuvers in its repertoire, the drill is unique in its capabilities and complexities. (Watch video of Curiosity's "Seven Minutes of Terror.")

Sample system chief engineer Louise Jandura, who has worked on the drill for eight years, said the Curosity team had made eight different drills before settling on the one now on the rover. The team tested each drill by boring 1,200 holes on 20 types of rock on Earth.

She called the successful drilling "historic" because it gives scientists unprecedented access to material that has not been exposed to the intense weathering and radiation processes that affect the Martian surface.

Mini-laboratories

The gray powder will be routed to the two most sophisticated instruments on Curiosity—the Sample Analysis at Mars (SAM) and Chemistry and Mineralogy (CheMin).

SAM, the largest and most complex instrument onboard, operates with two ovens that can heat the sample up to 1,800°F (982°C), turning the elements and compounds in the rock into gases that can then be identified. SAM can also determine whether any carbon-based organic material is present.

Organics are the chemical building blocks of life on Earth. They are known to regularly land on Mars via meteorites and finer material that rains down on all planets.

But researchers suspect the intense radiation on the Martian surface destroys any organics on the surface. Scientists hope that organics within Martian rocks are protected from that radiation.

CheMin shoots an X-ray beam at its sample and can analyze the mineral content of the rock. Minerals provide a durable record of environmental conditions over the eons, including information about possible ingredients and energy sources for life.

Both SAM and CheMin received samples of sandy soil scooped from the nearby Rocknest outcrop in October. SAM identified organic material, but scientists are still trying to determine whether any of it is Martian or the byproduct of organics inadvertently brought to Mars by the rover. (See "Mars Rover Detects Simple Organic Compounds.")

In the next few days, CheMin will be the first to receive samples of the powdered rock, and then SAM. Given the complexity of the analysis, and the track record seen with other samples, it will likely be weeks before results are announced.

The process of drilling and collecting the results was delayed by several glitches that required study and work-arounds. One involved drill software and the other involved a test-bed problem with a sieve that is part of the process of delivering samples to the instruments.

Lead systems engineer Daniel Limonadi said that while there was no indication the sieve on Mars was malfunctioning, they had become more conservative in its use because of the test bed results. (Related: "A 2020 Rover Return to Mars?")

Lead Pistorius Cop Facing Attempted Murder Charge












The South African Police Service said today that Hilton Botha, the lead investigator in the Oscar Pistorius murder case, will no longer be part of the investigation after this week's bail hearing ends.


The decision comes in light of the revelation that the detective is facing his own attempted murder charges in connection to a 2011 shooting.


"We became aware of the allegations that surfaced yesterday against the investigating officer in the Oscar Pistorius case," Police Chief Reah Piyega said at a news conference today.


Botha and other police officers allegedly fired at passengers in a vehicle two years ago.


"We were aware of the matter, it was in court, it was withdrawn and yesterday we got the decision of the NPA [National Prosecuting Authority]," she said. "At this point in time, it is premature for anyone of us to pre-judge this case."


PHOTOS: Paralympic Champion Charged in Killing


Botha will be allowed to finish the Pistorius bail application that ended its third day in court this afternoon.


Whether Pistorius is granted bail or not, Botha will not be part of the investigation team as it prepares for the Olympic sprinter's trial.


Piyega said Botha is "highly experienced" after 22 years of service and the matter "doesn't take away that experience."

Oscar Pistorius Bail Hearing: New Evidence Revealed Watch Video





A decision in Pistorius' bail application is expected Friday.


"With that part over, Botha has done what he was supposed to do and now we are going into the long haul of the investigation," Piyega said.


Botha is scheduled to appear in court in May on seven counts of attempted murder in connection to the October 2011 incident in which he and two other officers allegedly fired shots at a minibus they were attempting to stop. It's unclear whether any of the passengers were injured.


Botha has been outlining details this week at the Olympic runner's bail hearing of his investigation into the Feb. 14 shooting death of Reeva Steenkamp at Pistorius' home in Pretoria, South Africa. Botha was one of the first officers to arrive at the scene, where Steenkamp, a 29-year-old model, was found fatally shot three times.


Pistorius, a double-amputee who walks on carbon fiber blades, says he killed his girlfriend accidentally.


Prosecutors say they were unaware of the charges against the detective when he took the stand this week, according to The Associated Press.


"The prosecutors were not aware of those charges [against Botha]," Medupe Simasiku of the National Prosecution Agency said. "We are calling up the information so we can get the details of the case. From there, we can take action and see if we remove him from the investigation or if he stays."


FULL COVERAGE: Oscar Pistorius Case


Botha muddled testimony and eventually admitted Wednesday at Pistorius' bail hearing that the suspect's account of the Valentine's Day shooting did not contradict the police's version of events.


A spokesman for the NPA admitted today that charges pending against Botha were not helpful for the credibility of the prosecution's case, but that the case would hinge on forensic evidence, not the testimony of a police officer.


Pistorius has argued in court that he was closing his balcony doors when he heard a noise from the bathroom. Fearing an intruder, and without his prosthetic legs on, he grabbed a gun from under his bed and fired through the closed bathroom door, he told the court.

Harness vast power of quantum computers… for sums



































Quantum computers sound exotic but their power may lie in solving mundane equations – fast.











Until now these systems have been geared towards tasks such as factorising huge numbers, which would not be much use outside cryptography.













In 2009, Seth Lloyd at the Massachusetts Institute of Technology and colleagues devised a quantum algorithm for solving systems of linear equations, such as determining two unknown variables that appear in two separate equations. This example is classroom algebra, but scale it up to millions of variables and the same mathematics drives weather forecasting, image processing and traffic analysis.












Lloyd's team showed that while the number of steps in the classical algorithm scales with the number of equations, for the quantum version, it scales with the logarithm of that number – equivalent to solving a trillion equations in a few hundred steps.











Entangled implementation













"You basically take a classical algorithm that sucks and do it in quantum parallel," says Lloyd, taking advantage of the fact that a quantum computer can perform multiple calculations at the same time.












Now Stefanie Barz's team at the University of Vienna, Austria, has got Lloyd's algorithm working on a very simple quantum computer, using two entangled photons to solve a system of two equations (arxiv.org/abs/1302.1210). Though too simple to be useful in itself, it is a neat demonstration. "It is very nice that they've been able to implement it," says Lloyd.











Meanwhile, Jiangfeng Du's team at the University of Science and Technology of China, Hefei, has demonstrated Lloyd's algorithm with a four-equation system (arxiv.org/abs/1302.1946). But they used a quantum computer based on the spins of atomic nuclei that some physicists fear won't scale.
