Hispanic, Afro-Caribbean and North American influences meld in Puerto Rico, a self-governing commonwealth that belongs to the United States.

Puerto Rican voters, who elect a governor for the island, have tended to favour parties that support the union with the US. Puerto Ricans do not pay US income tax, and the island receives federal funds.

There is an established cycle of migration between Puerto Rico and the US; hundreds of thousands of Puerto Ricans have lived and worked in New York and other cities.

The once substantial US military presence has been scaled down with the closures of a major naval base and a bombing range. Rancour over the latter grew after a civilian employee was killed by a stray bomb.

Explorer Christopher Columbus claimed Puerto Rico for Spain in 1493, heralding an influx of Spanish settlers. The newcomers, and the diseases they brought with them, decimated the territory's Taino indian population.

The main settlement, San Juan, became an important Spanish outpost. Slaves were brought to the island in the 16th and 17th centuries.

Puerto Rico's landscape is varied, and includes rainforests in the north-east. The territory is prone to hurricanes.

Tourism is an important money-earner; the island receives millions of visitors each year and is a port-of-call for cruise liners.

Once the centre of the Ottoman Empire, the modern secular republic was established in the 1920s by nationalist leader Kemal Ataturk.

The level of public debt was already relatively low, and although the effects of the recession were still felt, by 2010 the Turkish economy had started to bounce back – to the extent that by the beginning of 2011, concerns were being raised over whether the boom was sustainable.

Concerns over the potential for conflict between a secular establishment backed by the military and a traditional society deeply rooted in Islam resurfaced with the landslide election victory of the Islamist-based Justice and Development Party (AKP) in 2002.

The secularist opposition has on several occasions since then challenged the constitutional right of the AKP to be the party of government. In March 2008 the Constitutional Court narrowly rejected a petition by the chief prosecutor to ban the AKP and 71 of its officials, including President Abdullah Gul and Prime Minister Recep Tayyip Erdogan, for allegedly seeking to establish an Islamic state.

The government has accused military officers of plotting to overthrow it through an alleged secret organisation called Ergenekon (Sledgehammer), which led to the jailing of three generals for 20 years and lesser sentences against more than 300 other officers in 2012, as well as dividing public opinion. The officers involved accuse the government of a show trial to neutralise the anti-Islamist influence of the armed forces in politics.

The chiefs of staff resigned in the summer of 2011 in protests at the arrests of officers, and the government rather than the military appointed their successors for the first time.

Turkey became an EU candidate country in 1999 and, in line with EU requirements, went on to introduce substantial human rights and economic reforms. The death penalty was abolished, tougher measures were brought in against torture and the penal code was overhauled.

Reforms were introduced in the areas of women's rights and Kurdish culture, language, education and broadcasting. Women's rights activists have said the reforms do not go far enough and have accused the government of lacking full commitment to equality and of acting only under EU pressure.

After intense bargaining, EU membership talks were launched in October 2005. Accession negotiations are expected to take about 10 years. So far, the going has not been easy.

Turkey has long been at odds with its close neighbour, Greece, over the divided island of Cyprus and territorial disputes in the Aegean.

The breakthrough in its EU membership talks came just weeks after Turkey agreed to recognise Cyprus as an EU member – though it qualified this conciliatory step by declaring that it was not tantamount to full diplomatic recognition.

Several European countries continue to have serious misgivings over Turkey's EU membership, and Germany and France have called for it to have a "privileged partnership" with the EU instead of full membership.

Turkey long saw itself as the eastern bulwark of the Nato alliance, and underlined this by having close ties with Israel. But under Mr Erdogan Turkey has taken a pro-Palestinian and openly confrontational approach to Israel, counting on its new prestige in Arab countries to boost its regional standing as a power broker.

The outbreak of civil war in neighbouring Syria has seen Turkey's stance move from detente with the Assad government to open support for the rebels, albeit stopping short of military assistance. This has left Turkey exposed within the Nato alliance, which continues to keep the Syrian conflict at arms length, but has further enhanced Turkey's prestige in Arab public opinion.

Turkey is home to a sizeable Kurdish minority, which by some estimates constitutes up to a fifth of the population. The Kurds have long complained that the Turkish government was trying to destroy their identity and that they suffer from economic disadvantage and human rights violations.

The Kurdistan Workers Party (PKK), the best known and most radical of the Kurdish movements, launched a guerrilla campaign in 1984 for a homeland in the Kurdish heartland in the southeast. Thousands died and hundreds of thousands became refugees in the ensuing conflict with the PKK, which Turkey, the US and the European Union deem a terrorist organisation.

Kurdish guerrilla attacks briefly subsided after the 1999 capture of PKK leader Abdullah Ocalan, but soon began to increase again.

Partly in a bid to improve its chances of EU membership, the government began to ease restrictions on the use of the Kurdish language from 2003 onwards. As part of a new "Kurdish initiative" launched in 2009, it pledged to extend linguistic and cultural rights and to reduce the military presence in the mainly Kurdish southeast of the country.

Although fighting continued, the PKK signalled its readiness to cease fire in 2010. After months of talks, Abdullah Ocalan ordered his fighters to stop attacking Turkey and withdraw from the country from May 2013, effectively ending the insurgency.

A $15m computer that uses "quantum physics" effects to boost its speed is to be installed at a Nasa facility.

Effectively, it can try all possible solutions at the same time and then select the best.

University researchers will also get 20% of the time on the machine via the Universities Space Research Agency (USRA).

Nasa will likely use the commercially available machine for scheduling problems and planning.

Canadian company D-Wave Systems, which makes the machine, has drawn scepticism over the years from quantum computing experts around the world.

Until research outlined earlier this year, some even suggested its machines showed no evidence of using specifically quantum effects.

Quantum computing is based around exploiting the strange behaviour of matter at quantum scales.

Most work on this type of computing has focused on building quantum logic gates similar to the gate devices at the basis of conventional computing.

But physicists have repeatedly found that the problem with a gate-based approach is keeping the quantum bits, or qubits (the basic units of quantum information), in their quantum state.

"You get drop out… decoherence, where the qubits lapse into being simple 1s and 0s instead of the entangled quantum states you need. Errors creep in," says Prof Alan Woodward of Surrey University.

Instead, D-Wave Systems has been focused on building machines that exploit a technique called quantum annealing – a way of distilling the optimal mathematical solutions from all the possibilities.

Annealing is made possible by physics effect known as quantum tunnelling, which can endow each qubit with an awareness of every other one.

"The gate model… is the single worst thing that ever happened to quantum computing", Geordie Rose, chief technology officer for D-Wave, told BBC Radio 4's Material World programme.

"And when we look back 20 years from now, at the history of this field, we'll wonder why anyone ever thought that was a good idea."

Dr Rose's approach entails a completely different way of posing your question, and it only works for certain questions.

But according to a paper presented this week (the result of benchmarking tests required by Nasa and Google), it is very fast indeed at finding the optimal solution to a problem that potentially has many different combinations of answers.

In one case it took less than half a second to do something that took conventional software 30 minutes.

A classic example of one of these "combinatorial optimisation" problems is that of the travelling sales rep, who needs to visit several cities in one day, and wants to know the shortest path that connects them all together in order to minimise their mileage.

The D-Wave Two chip can compare all the possible itineraries at once, rather than having to work through each in turn.

Reportedly costing up to $15m, housed in a garden shed-sized box that cools the chip to near absolute zero, it should be installed at Nasa and available for research by autumn 2013.

US giant Lockheed Martin earlier this year upgraded its own D-Wave machine to the 512 qubit D-Wave Two.

CHICAGO — Here’s a secret about the workout portions of the NBA combine: For the most part, it’s worthless. Since the NBA did away with five-on-five drills in 2009 — largely due to the fact that too many nervous agents were advising clients not to participate, causing attendance in the combine to dip — executives have been limited to watching big men post up against oversized pads and guards take uncontested jumpers. “Anyone that says they can learn something about a player from that,” said an Eastern Conference executive, “has never seen the player.”

What is useful are the interviews, when team officials can poke and prod a prospective draft pick. North Texas forward Tony Mitchell said his interview with Detroit involved a series of rapid fire questions, requiring him to think quickly. UCLA’s Shabazz Muhammad said he was asked repeatedly about the NCAA investigation into him and to clarify how old he was. Pittsburgh’s Steven Adams said Dallas brought a sports psychologist to “mentally torment” him. Some players were interviewed by a handful of teams, some by as many as 15.

The interviews are private, but in the case of many players, some of the questions league execs are not hard to figure out. Here’s a sample of how some players answered some of those questions.

SI.com: Your father, Barry Larkin, is a Hall of Fame baseball player. Why didn’t you get into baseball?

Shane Larkin: “Pete Rose and Tony Perez taught me how to hit. Tony Perez had the whole bat waggle and Pete Rose lifted his leg. I had those things in my game early on, as an eight-year old. I was playing baseball at a YMCA in Orlando and when I came up to bat my coach saw my whole routine and he told me ‘Stop what you’re doing; whoever taught you how to hit doesn’t know what they are talking about. Give it up. Plant your foot, keep the bat still and you will be way more successful.’ So I tried to do what he said, but I couldn’t hit the rest of the season. And that was the last year I played organized baseball.”

SI.com: Did you ever feel pressure to play baseball because of your father?

SL: “Not really, because he never put any pressure on me. Of course, when I was in the clubhouse the guys on his team were always like, ‘When are you going to get out here on the field,’ but it was never pressure from my Dad. He actually wanted me to play football. That was the only sport he made me play. I wanted to play soccer because the kids at my elementary school played soccer, but he said, ‘Football was fun, I [have to play] football — he went to Michigan on a football scholarship — and if you don’t like it you don’t have to play again.’”

SI.com: You were a mediocre shooter before this season. What changed?

Victor Oladipo: “I just stayed in the gym. It was repetition after repetition. I felt like before, it was all a mental thing for me. I realized that if I miss, so what. I just go to the next shot. Once I realized that I’m just going to shoot the good shots, the open shots, the shots I feel like are the best, I’m going to make them at a high level. I started shooting with confidence, and they started going in at a high rate.”

SI.com: So you used to get rattled when you shot?

VO: “Yeah, I would say so. My first two years, whenever I missed a shot I would be like, ‘Oh, no need to keep shooting, the next probably isn’t going to go in either.’ This year, if I missed, I would shoot the next one with the same confidence. If I missed, it was rare. I knew the next one was going to go in.”

MANNIX: Oladipo rises in NBA draft Big Board 7.0

SI.com: How do you address questions about you not playing hard all the time last year?

Tony Mitchell: “Our season was so tough, I couldn’t get up for games, somewhat. We had a losing record, and it was hard. My effort was up and down. It should have been straight. There is no excuse. It definitely hurt my stock. [Without the questions], I think I would go in the lottery. Each and every team has asked me about it. I understand this is a business. They want to make sure I’m the right fit. I’m ready to prove them wrong.

SI.com: Do you get the sense that teams believe that you are going to work hard all the time?

TM: “Really, it’s a question mark. They just don’t know. I have to show it. I can’t talk about it anymore. I’ve accepted it. I have expectations, and I have to live up to them.

SI.com: You have compared your game to Kenneth Faried. What similarities do you see?

TM: “Our athleticism. I believe I can rebound just like him. Faried works tremendously hard and I know I can do the same thing.”

SI.com: You said at the end of the season that you would be delusional to think you were ready for the NBA. And here you are. What changed?

Archie Goodwin: “I had a talk with my coach and my family, and at the end of the day I felt it was the best decision for me going forward. I wanted to see where I’m at. Coach [John Calipari] said whether I stayed or not, he was going to battle for me. He wanted me to stay, but at the same time he would respect my decision if I wanted to leave. These last few weeks, he has been in my corner. We talk all the time. I was fortunate to have him as someone to vouch for me going forward.”

SI.com: Many have said that Kentucky’s vaunted recruiting class forced you into this decision. Is that true?

AG: “It didn’t impact my decision at all. Those guys are good players, but I feel I can compete with anybody. They didn’t have anything to do with it. It’s not about this class. Because the next season people could say I was leaving because of the next one. It would be an ongoing battle, nonstop. I don’t pay any attention to it. This was about my family and the way I personally felt.”

SI.com: It has been speculated that you left Pitt after your freshman season because you needed to take care of your family back in New Zealand. Is that true?

Steven Adams: “It was strictly a personal decision. I talked about it with my family but no one asked me to leave. I left because the best coaches in the world are in the NBA. They can help me progress. [Pitt] was good for me. Jaime [Dixon] is a really successful coach. He taught me a lot.”

SI.com: Did you think you were going to come to Pitt and put up the kind of numbers you did in New Zealand?

SA: “No, no chance. The competition is so much higher than in New Zealand. I wasn’t used to playing against much taller and stronger people. Basketball players look like rugby players in New Zealand, short and stocky. Here, they are really tall. I was learning to use my body to get a hook shot off, to outrebound big men by using my body. It was an adjustment.”

SI.com: It has been written that one of the reasons you didn’t go back to USC is because the new coach (Andy Enfield) didn’t recruit you back very hard. Is that true?

Dewayne Dedmon: “I mean, they did what they were supposed to do. I talked to all the coaches, had meetings with all the coaches. At the end of the day, my mind was made up to come out. They were good meetings, but I was still unsure about next year’s coaching staff. I wasn’t willing to put myself in jeopardy because of what they would do on the court. Sometimes you get broken promises. You never really know. There is always that little gray area.

SI.com: Did you think you wouldn’t fit in the system Enfield ran at Florida Gulf Coast?

DD: “No, that’s the way I like to play. Going through the year we just had, with the coaching changes, with Kevin O’Neil getting fired, with the assistant coach coming in and a whole new coaching staff coming in … I basically had my mind made up. They recruited me to come back, and they did a good job, but I had decided.”

SI.com: You were a guard in high school, grew seven inches as junior, and now you are a center. What are the challenges in having to switch positions?

Kelly Olynyk: “It was challenging. Suddenly you’re inside, you’re focusing on post moves, you’re playing with your back to the basket — it’s something I had never done before. The way I describe it is trying to make a quarterback a kicker. Those are two different positions. I was a point guard in high school. Being from a smaller town in Canada, there wasn’t a lot of talent where I came from. I had to do a lot of stuff. I had to score, pass, facilitate, run the team. It was a tough transition [to center], but once I gained that I kept those guard skills as well, so I can be a dual threat.”

SI.com: The perception of you is that you can score in the NBA, but no one is sure if you can rebound and defend. What can you do to change that before the draft?

KO: “I don’t know. I changed my body a lot. I want to improve it even more. I think what has helped me a lot is playing with the national team, playing overseas with pros all the time. It gave me the confidence to know that I belonged playing at that next level. That was reassuring.”

SI.com: You didn’t play at all last season because of academic issues. How have you been able to stay sharp?

Ricky Ledo: “I competed every day in practice. Most of the times I practiced as the other team’s best player. I was involved heavily. I worked out a lot with [God] Shammgod; he helped me with my dribbling and shooting off the dribble. I’m not just a spot shooter.

SI.com: If you had wanted to go back to Providence, would you have been academically eligible?

RL: “I would have. And it was a tough decision. I thought if I stayed I definitely would have been a top pick next year. But I felt it was the right time to come out. I wanted to play in front of my friends and family (Ledo is from Providence, R.I.), and it was disappointing that I couldn’t. But I learned a lot not playing. I’m a better player than I was last year.”

SI.com: Are you the best shooter in this draft?

RL: “I would say one of them. Top-three.”

A nation with a proud cultural heritage, Poland can trace its roots back over 1,000 years. Positioned at the centre of Europe, it has known turbulent and violent times.

The shoots of political freedom were trampled again 16 months later when communist leader Wojciech Jaruzelski declared martial law. But the movement for change was irreversible. Elections in summer 1989 ushered in eastern Europe's first post-communist government.

The presence in the Vatican of Polish Pope John-Paul II was an important influence on the Solidarity movement throughout the 1980s. The Roman Catholic church remains a very potent force in Polish life.

In the years between the end of communism and EU accession, power in Poland switched between the centre right and the centre left. Successive governments faced sleaze allegations.

In elections in 2010, the victory of the centre-right Civic Platfrom saw Prime Minister Donald Tusk become the first Polish leader to be re-elected since the end of communism.

Success

Poland has made major economic strides since the fall of communism, and especially since joining the EU. In 2009, when all the major European economies were contracting because of the credit crunch, Poland was the only country in Europe to experience economic growth.

There has been marked success in creating a market economy and attracting foreign investment. Germany is now Poland's biggest trading partner. There was a massive movement of workers to western Europe in the years after Poland joined the EU, but the exodus slowed down after the global economic crisis took hold.

Poland still has a huge farming sector – agriculture accounts for about 60% of the country's total land area – but the sector remains hampered by inefficiency, structural problems and lack of investment.

Warsaw's profile on the international stage was raised by its support for the US-led military campaigns in Iraq and Afghanistan. Polish peacekeeping troops served in south-central Iraq from 2003 until 2008, and the country has also contributed a sizeable contingent to the Nato peacekeeping force in Afghanistan.

The prospect of a deep sea "gold rush" opening a controversial new frontier for mining on the ocean floor has moved a step closer.

The idea of exploiting the gold, copper, manganese, cobalt and other metals of the ocean floor has been considered for decades but only recently became feasible with high commodity prices and new technology.

Conservation experts have long warned that mining the seabed will be highly destructive and could have disastrous long-term consequences for marine life.

The ISA study itself recognizes that mining will cause "inevitable environmental damage".

But the report comes amid what a spokesman describes as "an unprecedented surge" of interest from state-owned and private mining companies.

The number of licences issued to prospect for minerals now stands at 17 with another seven due to be granted and more are likely to follow. They cover vast areas of the Pacific, Atlantic and Indian Oceans.

One of the most recent to be granted was to UK Seabed Resources, a subsidiary of the British arm of Lockheed Martin, the American defence giant.

Under the UN Convention on the Law of the Sea, the ISA was set up to encourage and manage seabed mining for the wider benefit of humanity – with a share of any profits going to developing countries.

Now the ISA is taking the significant step of moving from simply handling bids for mineral exploration to considering how to license the first real mining operations and how to share the proceeds.

The ISA's legal counsel, Michael Lodge, told the BBC: "We are at the threshold of a new era of deep seabed mining."

The lure is obvious. An assessment of the eastern Pacific – a five million sq km area known as the Clarion-Clipperton Zone – concluded that more than 27 billion tonnes of nodules could be lying on the sand.

Those rocks would contain a staggering seven billion tonnes of manganese, 340 million tonnes of nickel, 290 million tonnes of copper and 78 million tonnes of cobalt – although it's not known how much of this is accessible.

A map shows the spread of licensed areas across the zone.

According to the planning study, the ISA faces the challenge of trying to ensure that nodule mining's benefits will reach beyond the companies themselves while also fostering commercially viable operations.

The plan relies on providing operators with the right incentives to risk what would be expensive investments without losing the chance for developing countries to get a slice of the proceeds.

But the ISA identifies what it calls a "Catch-22" in this brand new industry as it tries to assess which companies are skilled enough to carry out the work.

"Competence cannot be gained," it says, "without actual mining at a commercial scale, but at the same time mining should not be allowed without prior demonstration of competence."

A key factor in the ISA's thinking is the need for environmental safeguards, so the document calls for monitoring of the seabed during any mining operation – though critics wonder if activity in the ocean depths can be policed.

The prospect of deep sea mining has already sparked a vigorous debate among marine scientists, as I found earlier this year on a visit to the British research ship, James Cook, exploring the hydrothermal vents of the Cayman Trough.

The expedition's chief scientist, Dr Jon Copley, a biologist from the University of Southampton, urged caution.

"I don't think we own the deep ocean in the sense that we can do what we like with it," he said. "Instead we share responsibility for its stewardship.

"We don't have a good track record of achieving balance anywhere else – think of the buffalo and the rainforest – so the question is, can we get it right?"

And Prof Paul Tyler, also a biologist, of the National Oceanography Centre, warned that unique species would be at risk.

"If you wipe out that area by mining, those animals have to do one of two things: they disperse and colonise another hydrothermal vent somewhere or they die.

"And what happens when they die is that the vent will become biologically extinct."

However, marine chemist Prof Rachel Mills, of the University of Southampton, called for a wider debate about mining generally on the grounds that we all use minerals and that mines on land are far larger than any would be on the seabed.

She has carried out research for Nautilus Minerals, a Canadian firm planning to mine hydrothermal vents off Papua New Guinea.

"Everything we are surrounded by, the way we live, relies on mineral resources and we don't often ask where they come from," she said.

"We need to ask whether there is sustainable mining on land and whether there is sustainable mining in the seas.

"I actually think it is the same moral questions we ask whether it's from the Andes or down in the Bismarck Sea."

This debate is set to intensify as the reality of the first mining operations comes closer.

David Shukman presents a documentary on deep sea mining on Discovery on the BBC World Service on Monday.

Malawi, a largely agricultural country, is making efforts to overcome decades of underdevelopment and the more recent impact of a growing HIV-Aids problem.

Most Malawians rely on subsistence farming, but the food supply situation is precarious and the country is prone to natural disasters of both extremes – from drought to heavy rainfalls – putting it in constant need of thousands of tonnes of food aid every year.

Malawi has been urged by world financial bodies to free up its economy, and has it has privatised many loss-making state-run corporations.

Since 2007 the country has made real progress in achieving economic growth as part of programmes instituted by the government of President Mutharika in 2005. Healthcare, education and environmental conditions have improved, and Malawi has started to move away from reliance on overseas aid.

Its single major natural resource, agricultural land is under severe pressure from rapid population growth, although the government's programme of fertilizer subsidies has dramatically boosted output in recent years, making Malawi a net food exporter.

Tens of thousands of Malawians die of Aids every year. After years of silence, the authorities spoke out about the crisis. A programme to tackle HIV-Aids was launched in 2004, with President Muluzi revealing that his brother had died from the disease.

However, the sources said, the two players refused to attend.

The sources also claim that Chandila told interrogators that in the 2012 IPL season, the last two overs of a match between Delhi Daredevils and Rajasthan Royals might have been fixed.

Amidst media reports that Rajasthan Royals co-owner Shilpa Shetty, her husband Raj Kundra and captain Rahul Dravid would also be questioned, police denied calling them for the probe.

The police said they were able to trail the connection when they started to intercept the calls of aides of Tiger Memon, who is wanted in connection with the 1993 Bombay bombings is said to be in Dubai, since March 2013.

They also said that escorts were used to lure the players into the net.

Sources also said that when Sreesanth was arrested from the Trident Hotel in south Mumbai’s Nariman Point late on Wednesday, he was with a woman. Police refused to give more details about her but ruled out her involvement in spot-fixing.

The three players, who along with 11 bookies have been remanded to five days’ police custody, have been lodged in the Special Cell in Lodhi Colony.

Police said all the three players have confessed to their crime.

A senior officer said Sreesanth was ‘cooperating’ in the investigations, while Chavan ‘broke down’ during questioning.

“He [Chavan] accepted that he made a mistake,” the officer said. “He also accepted his role in spot fixing.”

Of the 11 bookies, Chandresh Patel, who was arrested from Mumbai’s Andheri area, may be the main conspirator in the case and could have been involved in spot fixing for several years.

Sources also said that Sreesanth was directly approached by cricketer-turned-bookie Jiju Janardhan, his distant cousin who has also been arrested. He had played for Kerala.

Although the three accused have allegedly confessed to their crimes, their families and lawyers said they were innocent.

Deepak Prakash, Sreesanth’s lawyer, said: “Sreesanth has been falsely or mistakenly arrested. They [Delhi Police] have got some wrong information or mistakenly arrested him.”

Delhi police said more teams have been sent to other states to conduct raids.

Home Minister Sushilkumar Shinde, meanwhile, congratulated Delhi police for the investigations. Asked about the underworld link in the betting racket, he said: “Police is investigating.”

NEW YORK — Lamont Peterson understands his days of being just Lamont Peterson may be over.

Huh?

See, to many he’s Lamont Peterson, IBF junior welterweight champion, D.C. kid who rose from the horrors of the streets to become a world champion. He slept in cars, used newspaper for toilet paper and, Peterson told me recently, had he not met trainer Barry Hunter when he was 11, he probably would be dead or in prison.

To others… well… he’s the guy who flunked a drug test, the guy who tested positive for synthetic testosterone, the guy whose career, including a defining win over Amir Khan, will always be shrouded in some doubt.

“I’m still trying to bury that whole drug testing situation,” Peterson admitted. “People seem to forget very fast about how I performed up to that Khan fight. And then, after the Khan fight, a lot of people were saying I need this and that and this and that. But people forget that I’ve already been a top fighter and I just want to get paid to go out and to prove to people that Lamont Peterson’s still a top fighter and a world champion.”

Peterson’s explanation for the failed test — he was prescribed the testosterone by a doctor to treat his abnormally low levels and that it wasn’t enough to enhance his performance in the ring — had its share of believers and doubters. The WBA didn’t buy it; the sanctioning body stripped Peterson of the belt he won against Khan. The IBF did buy it and allowed Peterson to keep its version of the 140-pound title.

In February, Peterson (31-1) ended a 14-month layoff when he defended his title against Kendall Holt. Peterson looked sluggish early, absorbing plenty of power shots. But in the fourth round, Peterson seized control, steadily advancing on Holt, punishing him with short, crisp punches. Holt went down in the fourth and was finished off in the eighth, when a surging Peterson buried him under an avalanche of punches that forced a stoppage.

“That’s kind of how I work or go about things,” Peterson said. “People can call me a slow starter; I guess that’s the case. I take my time. I figure things out, and after a few rounds I start taking over.”

On Saturday night, Peterson will continue his road back when he takes on Lucas Matthysse at Boardwalk Hall in Atlantic City (Showtime, 9 pm). No titles will be at stake — Matthysse (33-2) is the interim WBC champion, and because the IBF does not recognize interim titles it would not sanction it as a unification fight, Golden Boy Promotions matchmaker Eric Gomez said, so instead it will be fought at a 141-pound catchweight — but there is plenty on the line. The winner is earmarked for a shot at junior welterweight kingpin Danny Garcia in the fall.

“Every fight right now is important to me,” Peterson said, “because you’re at the top level right now and every fight that you win, every fight that you’re in is a big fight and if you win that big fight you’re going to a bigger fight. I’m 29 years old now. So I’m, some people might not say this but, on the tail end of my career. I don’t plan on doing this much longer.”

Peterson claims to be motivated to fight Matthysse by the urban legend that he has become. Despite losing his two most significant fights — close decision defeats to Zab Judah in 2010 and Devon Alexander in 2011 — Matthysse is considered one of the most feared fighters in the division. He has stopped his last five opponents, including a crushing first-round knockout of Mike Dallas Jr. last January.

“It was the media who said things like, ‘No one wants fight him,’” Peterson said. “I’m in the division, in the same division, when I hear things like that, that are not true, it kind of gets under my skin. I’m like, ‘I’ll fight anyone.’ Not being angry or anything, it’s just the fact that I want to prove to everyone I’m the best at the weight class.

“A lot of people, when you hear about the best in the weight class, they were saying his name. So of course that was the person that I wanted to fight to prove myself and to let people know that someone out here wanted to fight him.”

The taint of the positive test will never fully fade, not with the Internet, not with Wikipedia, not with search engines linking it to his name. But Peterson knows he can win back some of the fans he lost with clean tests and entertaining fights. And matching his fight in the pocket style with the heavy handed Matthysse is close to a can’t-miss.

“I normally don’t worry about anybody’s punching power before the fight,” Peterson said. “I understand that it’s boxing and I’m going to get hit. That’s something that’s a given. If I get hit hard or not, that really doesn’t make a difference to me. I’m willing to take any shot that anybody can give out.”

A Hong Kong taxi driver prosecuted for overcharging a passenger by HK$0.5 (£0.04; $0.06) has had the case against him thrown out.

The lawsuit, which was withdrawn on Thursday after the prosecution offered no evidence, lasted six months.

Tam Hoichi said the case had tired him out, and he wanted an explanation as to why he was sued.

Hong Kong taxi drivers frequently round up to the nearest dollar when giving change.

It is considered a common practice by many drivers and passengers in Hong Kong.

The overcharging incident is reported to have occurred during a taxi ride in October.

The journey fare was HK$136.5 (£12; $18), and Mr Tam kept HK$0.5 of the change, the South China Morning Post (SCMP) reported.

The passenger did not demand the missing change at the time, but later reported the incident to the police, the SCMP said.

Mr Tam attended the trial hearing on Thursday morning on charges of "taxi overcharge", but was cleared after the case was dismissed.

"The case was reviewed by the Prosecutions Division," Hong Kong's Department of Justice said. "Given the trivial nature… it was considered not appropriate to proceed with it."

Mr Tam told reporters at the court that he felt the lawsuit was "really not just".

"I want to know why the opposite side, for the reason of this small amount, would want to sue me," he said.

A representative for Hong Kong taxi and minibus drivers told AFP news agency that the court case had wasted taxpayers' money and time.

Sao Tome and Principe, once a leading cocoa producer, is poised to profit from the commercial exploitation of large offshore reserves of oil.

From the late 1400s Portugal began settling convicts on Sao Tome and establishing sugar plantations with the help of slaves from the mainland. The island was also important in the transshipment of slaves.

The colony's aspirations for independence were recognised after the 1974 coup in Portugal and at first the Movement for the Liberation of Sao Tome and Principe was the country's sole political party. However, the 1990 constitution created a multi-party democracy. The island of Principe assumed autonomy in 1995.

Sao Tome and Principe is trying to shake off its dependence on the cocoa crop. Falls in production and prices left the island state heavily reliant on foreign aid. The government has been encouraging economic diversification and is set to exploit the billions of barrels of oil which are thought to lie off the country's coast.

Drilling is under way and commercial production is expected to begin within a few years.

Promoters of tourism say the islands have plenty for visitors to see. But hurdles include ignorance about the country, the difficulties of getting there, and what some say is an exaggerated fear of malaria.

Editor’s note: In the Human Factor, we profile survivors who have overcome the odds. Confronting a life obstacle — injury, illness or other hardship — they tapped their inner strength and found resilience they didn’t know they possessed. Evan and Eric Edwards have life-threatening allergies and wanted to develop a better way to deliver epinephrine, a drug used to treat serious allergic reactions. Their vision started shortly after graduating from high school and became a reality soon afterward.

Like many kids, we were unaware and felt invincible. We didn’t worry too much about managing our allergies. That changed after the first severe allergic reaction either of us had.

Evan was playing at a friend’s house when he ate what he had been assured was a “fake peanut.” Almost immediately, it was apparent that something was very, very wrong. Luckily, his friend’s dad also happened to be Evan’s doctor; he treated him immediately, and the incident was resolved.

Life-threatening allergies were much less common when we went to school, so we really stood out as the “strange twins with allergies” — those guys who had to sit at a separate table by themselves at lunchtime. It is unfortunate that severe allergies are much more widespread now, but there is a silver lining: People and organizations are more aware and better able to support the children and adults who suffer.

The idea to develop a new epinephrine auto-injector (commonly known as an EpiPen), specifically designed for the needs of patients like us, came about the summer after we graduated high school. We were on our way to a family vacation in Europe, and it looked as if, once again, the two of us had not packed our EpiPens. They were too bulky so we often didn’t carry them.

After the usual finger-pointing and questions about why we didn’t carry something that could save our lives, the idea of developing a smaller, more portable type of epinephrine auto-injector was born.

At the time, we had recently selected our college majors. (Evan went into the engineering program at the University of Virginia, and Eric chose pre-med/medicine at Virginia Commonwealth University.) We decided to customize our education to develop the skills necessary to make this invention a reality. At the start of each school year we reviewed our course options and decided together which classes to take that would help us achieve our goal.

Our first real funding came from winning a collegiate inventors’ grant from the National Collegiate Inventors and Innovators Alliance. It was at that point we knew we were on our way.

Soon after we confirmed what we had already suspected: that developing a new pharmaceutical product is extremely complicated. To do it successfully would require deep industry expertise. We founded Intelliject, which now has a leadership team with more than 100 years of combined experience in the pharmaceutical industry.

We are fortunate to work with a team of industry veterans who are just as committed to patients as we are. As we say, the patients are the real experts — we just need to create the opportunities to capture their insight and design products that truly address their needs. Our entire approach puts the user at the center of development from the beginning of the process.

It is hard to describe the feeling now that Auvi-Q – the epinephrine auto-injector that is a culmination of the ideas we had all those years ago — is available in pharmacies across the United States (and as Allerject in Canada).

If you had asked us on the day of the launch in January, we would have told you that it simply can’t get any better than this. But we were wrong.

About a month after Auvi-Q’s launch, we read a Facebook post in which a mother described how her daughter had a severe allergic reaction. She described how Auvi-Q helped her by “having a voice walking through the steps in an emergency situation.” In her opinion, Auvi-Q saved her daughter’s life.

We can confidently say that there is no better feeling than that.
