>> union bank has put its financial strength to work for a wide range of companies, from small businesses to major corporations. what can we do for you? >> he was a dreamer. >> above the trees with my lips connected. >> were they my lips? >> she was a realist. >> you have to read it to see if he's an idiot or not. >> everything he wrote -- >> a thing of beauty is a joy forever. >> inspired the romance that would live forever. >> i would be anxious if i don't see her. >> i must warn you of the trap you're walking into. >> you know why i'm doing this. >> "bright star" rated pg now playing in select cities. >> and now "bbc world news." >> a glimmer of hope in the fight against aids. scientists say an experimental vaccine cut the risk of h.i.v. >> this is a major finding. first of all, it's the first

time we find an h.i.v. vaccine can reduce h.i.v. infections. >> a unanimous u.n. security council adopts a resolution aimed at a world without nuclear weapons. can they lead the way to a global economic recovery? the g-20 summit convenes in pittsburgh. welcome to bbc world news, on pbs in america also around the globe. coming up later for you, it's not made of cheese but it does contain water. spacecraft discover moon moisture. and the best treasure hunt ever. a fortune in ancient gold and silver is unearthed in an english field. >> after 25 years of searching, the best hope yet has emerged of a vaccine for h.i.v., the

virus that causes aids. researchers say their vaccine cuts the risk of one particular strain of h.i.v. infection by nearly 1/3. nothing before has been shown to give this limited protection. the trial on 16,000 volunteers in thailand is the biggest in the world. here's the bbc's medical correspondent. >> for a quarter of a simple, hiv-aids has brought havoc. dozens of vaccines have failed but now a glimmer of hope. it comes from the trial in this region of thailand which appears to show that a vaccine can protect against h.i.v.. >> this is a major finding. first of all, it's the first time we find an h.i.v. vaccine can reduce h.i.v. infections. and the other thing that's very critical here is that we know that a safe vaccine is

possible. >> 8,000 volunteers received the h.i.v. vaccine. the same number got a dummy jab. 51 of those immunized went on to get h.i.v. compared to 74 in the controlled group, suggesting the vaccine cuts the risk of infection by 31%. but the numbers are so small, it could be due to other things. this hospital is part of a global partnership to find an h.i.v. vaccine. research which had suffered repeated setbacks. when aids first appeared in the early 1980's, some scientists predicted that there would be a vaccine within a couple of years, but h.i.v. was proved to be such a chameleon virus that until today, all attempts have ended in utter failure. >> because the virus is so variable it can also hide itself within your cells and destroys the very immune system

you need to work against it and coupled together it's a formidable challenge. >> there's no doubt about the desperate need of the vaccine. worldwide around 33 million people are infected with h.i.v. there have been 25 million aids-related deaths. hardest hit is sub-saharan africa where the h.i.v. epidemic affects 22 million people. the strain of h.i.v. most prevalent in africa is different to that circulating in thailand, so it's unclear how well the vaccine might work there. a truly effective vaccine against this virus remains one of the great medical challenges, but this latest research will reinvigorate that quest. >> the u.n.'s world food program is estimating more than 20 million people in the horn of africa now need emergency

food aid, this because of two years of poor rainfall. the organization warns its cuts in its funding have made it more difficult to feed the hungry across kenya, somali, and ethiopia. iraqi security officials say 16 members of al qaeda in iraq have escaped from a prison. the group included five men sentenced to death in their role in attacks. it's believed they removed windows from a bathroom, crawled through and used a ladder to climb the jail walls. one has been recaptured. the palestinian president has accused israel of making a return to peace talks impossible. mahmoud abbas says there's no common ground for negotiations if the israeli government keeps building settlements on occupied land and will not discuss the future of jerusalem or palestinian refugees. well, as a sign of symbolism it because powerful and ratcheted up the power of iran over its

nuclear program. president obama in the chair for the first time, the u.n. security council has unanimously approved a resolution aimed at stemming the spread of nuclear weapons, reducing the risk of nuclear terrorism. jeremy bowen reports from the u.n. >> this is about fixing a goal, they were voting for a hope, a distant aspiration but the symbolism was strong. the world's most powerful states in agreement and an american president in the chair at the security council for the first time. >> the historic resolution we just adopted enshrines our shared commitment to the goal of a world without nuclear weapons. and it brings security council agreement on a broad framework for action to reduce nuclear dangers as we work toward that goal. >> critics of nuclear arms say they could start by living up to their obligations to reduce their own arsenals. but at the security council they were worrying about iran getting the bomb.

>> today i believe we have to draw a line in the sand. iran must not allow its actions to prevent the international community from moving forward to a more peaceful era. and as evidenced of its breach of international agreements grows, we must now consider far tougher sanctions together. >> in the general assembly, israel's prime minister attacked iran's president for saying the holocaust didn't happen. >> is this propertyo cole alive? >> the document -- is this propertyo cole -- is this protocol alive? >> he believes a nuclear armed iran would be as dangerous as nazi germany. >> the most urgent chance facing this body today is to prevent the tyrants of iran from acquiring nuclear weapons. >> iranians protested outside the u.n. last night against what they believe was a

fraudulent election victory by iran's president mahmoud ahmadinejad. >> he's against the whole world, he's against everything. >> inside, many delegations did not stay to hear president ahmadinejad speak. he defended his acollection, -- election, condemned israel and didn't mention the nuclear plans but used the same metaphor for negotiation as president barack obama. >> i said iran would shake all those honest that were honestly extended. iran denies developing nuclear weapons and it might face tougher sanctions now moscow and washington are a little closer. if diplomacy can't solve this growing crisis by the end of the year there will be more talk of israel or the americans attacking iran's nuclear installations. some intelligence agencies and mr. netanyahu was warning in the 1990's iran was close to

getting the bomb. some iran watchers still believe the dangers are being exaggerated. world leaders have to decide who is right. mistakes would be very costly. jeremy bowen, bbc news, new york. >> many of the world's most powerful people hot footed it from the u.n. in new york to the city of pittsburgh where the g-20 summit is getting underway. it's the third time the leaders of the world's 20 biggest economies have met since global finances went into a tailspin with the collapse of lehman brothers a year ago. our special correspondent is at the summit. there's been a lot of rhetoric about bankers bonuses. how much real appetite do you detect to really change the rules of the game? >> a great deal of appetite but only the part of some of the players, mike. largely the europeans. i was really struck, for example, by what the president of the european commission was saying earlier today and he said that the europeans are horrified that banks, many of whom were depending on the

taxpayer were continuing to hand out what he called exorbitant bonuses. it is rich language coming from a diplomat but if you look, for example, at the u.s. point of view, the attitude here is look, we don't set salaries as kind of a socialist thing to do to say we're going to attack salaries of a certain level. yes, the culture needs to change but i think the americans feel it can't be a top-down change in perhaps the way some of their european partners would like. the short answer is there is unlikely to be a dramatic agreement here on banking bonuses, mike. >> you've been pointing out that in contrast to the g-8, the point of this meeting is to hear the voices of the developing economies that are so crucial to stoking growth. is there some kind of powership going on? >> potentially. we're slightly distracted by voices because the protesters are across the river where we are now. i'm obviously within the security shuttle but there's a little bit of action from the protesters going on.

as far as the voices of the economies are concerned, i think yes, there is a move or an imminent move, especially when you look at, for example, the international monetary fund and the seats of the board there, traditionally they've been heavily weighted towards the u.s. and european countries and there are a lot of voices here from the emerging economies saying look, china, india, brazil, indonesia, all these kind of economies deserve more of the weight, more of the implements, and frankly some of the smaller european states will have to give this up. >> american consumers of course sometimes cast as the villains of the peace and where the subprime crisis began and we're going to hear a lot about curbing american greed and death. >> i don't know whether that kind of language will be used by leaders here but yes, here we are in america, in the united states, this is where the subprime has started up

that series of ripples that brought us into economic recession and there's a lot on the fact the u.s. has such a staggering amount of debt. so perhaps a way of rebalancing the global economic engine, as it were is that countries like china should spend more export and countries like america, consumers should consume less and save more. harder to achieve in practice and the issue if americans do curb their consumption, if they do start saving more, there is a danger of cutting off recovery before it's really underway, the danger of what they call a double dip recession. >> many thanks to that. now moving on to today's other main international business stories, i have to tell you, demonstrators how much the g-20 leaders have on their plate before any full-scale recovery from this downturn. russia's biggest carmaker is to cut nearly 30,000 jobs to tackle huge losses caused by a

sharp drop in sales. it amounts to more than a 1/4 of the work force that makes russia's best known car. and japan airlines is asking for a government bailout to help it stay in business. the carrier is in deep financial trouble and lost $1 billion from april to june and cut nearly 7,000 jobs earlier this month. >> the ousted honduran president manuel semenya, the organization of american states announced it's sending a delegation to seek a solution to the crisis where he was expelled from a military coup. from the streets of the capital, we now have this. >> there is something of a sense of normalcy returning to the streets here, the curfew has been lifted and the national air board has reopened as business as usual. the interim government is telling people here to get back to work and saying their safety

can be guaranteed by the police and army here. their presence is still heavy on the streets and of course there is still a standoff the a the brazilian embassy. manuel zaleya is still trapped inside the building claiming 10 of his supporters have been killed since monday and police say since monday's riots one person has died but seems a diplomatic solution is no closer. in principle, he has agreed to meet the interim leader here. as to when that happens, nobody knows. meanwhile, the only people to really suffer through this are the people of honduras. for every day there's been a curfew imposed here and cost this country $50 million. and for those that really lead a poor life, a hand-to-mouth existence, that's been a real hardship. >> we're hearing the u.n. security council is to discuss the honduran crisis on friday, that coming in from the reuters news organization. a man of afghan origin has been

charged with conspiracy. he was indicted in new york where counterintelligence agents believe he may have been planning to detonate bombs in trains. he works at an airport in denver, colorado. he and his father and another man have been charged to lying to investigators. all three maintain their innocence. the commander of american and nato led forces in afghanistan has denied any rift with the white house on whether to send more troops. general mcchrystal recently submitted a bleak assessment of the war and warned of a high risk of failure without a change in strategy and more forces. still to come on bbc world news, research suggests there are grounds for concern that toxins in commercial airliners can cause long-term neurological damage in pilots. >> first, though, it's called the left party and it seems to feel it's found the right party to shake up germany's political

landscape. steve rosenberg has been out on the campaign trail with the party that claims to be the voice of german workers and it does look set to take votes from the center left social democrats at this weekend's parliamentary election. >> the market square is a small stage but they're using it to call for big change. >> our message to the voters, it's not capitalism germany needs but a new kind of socialism. her party is the left, the robin hood of german politics that's growing increasingly popular. its members include disillusioned social democrats from western germany, people like sarah who want to belong to east germany's communist party. while the bigger parties have kept their election slogans vague like confidence and our country can do more. the left is more specific. it's the only parliamentary party calling for german troops

to pull out immediately from afghanistan. it wants to raise taxes on the rich, more money for education, less for the banks. simple messages which could help the left win more than 10% of the vote. the rise of the left party has transformed germany's political landscape and made it more fragmented and more uncertain, and the party which is suffering most as a result is the s.p.d., the social democrats. >> the left party won't win this election, but it already claims to have become what the social democrats have traditionally been in germany, the voice of the workers. steve rosenberg, bbc news, western germany. >> this is bbc world news, the latest headlines for you this hour, the biggest ever trial of

a new vaccine against h.i.v. has shown encouraging results. scientists say it can reduce the risk of one particular strain of up fecks by neeredly a -- strain of infection by nearly a 1/3. and they are calling for nuclear disarmament and nuclear proliferation. just yesterday we brought you the news in at least 22 people have been killed when a 100-meter chimney collapsed at a power plant in the central indian state. today the death toll in kaba rose 26 and there are fears that number could double. bbc south asia correspondent chris mohr us reports from delhi. >> a big rescue operation but fears of the number of dead will continue to rise and could do so dramatically. no one seems to know exactly how many people are in the vicinity when the huge chimney collapsed.

there was heavy rain and lightning when the accident took place and some eyewitnesses who weren't working were sheltering close to the shelter site. >> i could see the chimney crashing and felt like a stick. it was difficult to reach the spot, around 150 to 200 laborers came running and you could see mangled bodies of six to seven men who tried to remove the rubble. cranes and heavy earth moving equipment are now being used to shift the remains of the collapsed chimney which reached the height of about 100 meters when it came crashing down. some survivors say they believe substandard material was being used in the construction. the state government where the power plant is situated have ordered a judicial inquiry. chris morris, bbc news, delhi. >> new research links toxins

found in the air systems of commercial airliners and neurological damage suffered by pilots. an international collaboration between scientists suggest a direct link to the toxic syndrome and chemicals present in cockpit and cabin air supplies. >> are dangerous chemicals in the aircraft making us ill? it's estimated fume contamination of cabin and cockpit air occurs in at least one in 2,000 flights. this commercial pilot believes he was poisoned by the aircraft he flew. >> i have neurological problems like muscle twitching, tremors, and having trouble keeping up with the aircraft and thinking and doing the job. >> half of the air we breathe onboard is recycled but the other half is drawn through the heart of the jet engines. it's known as bleed air and

when faults occur potentially poisonous gases are pumped in the aircraft. scientists in the united states found toxins in the blood and fat tissue of 26 pilots. now new tests here in the u.k. show these chemicals have caused neurological damage. aircraft manufacturers b.a. systems and boeing say the air supplies in their planes meet health and safety standards but the jury is still out. observers await british government commissioned research due out in the next six months. campaigners and victims alike say this is an industry-wide problem. >> we'll follow that up for you, of course. scientists have found evidence there's much more water on the moon than previously thought. the water is not in liquid form but bound up in the rocks of the moon but nasa says there may be enough to sustain human life on the lunar surface. our sign correspondent has

more. . >> astronomers have gazed at it for thousands of years. astronauts have set foot on it but we still know relatively little about our nearest neighbor in the solar system. >> three, two, one, zero. >> last october, the indian space agency launched a probe to carry out a detailed survey of the lunar surface. the results have astonished scientists. previous missions had already found evidence of water the a the moon's poles but the new spacecraft has now discovered that the moon has much more water than we thought and it spread right across the lunar surface. there aren't any lakes or oceans here, the water is all locked away but scientists think one day factories could be built on the moon to extract water from the rocks. >> water is another resource to

drink and it's the raw material of rocket fuel that allows you to send rockets far into space. >> when astronauts brought back rocks 40 years ago scientists found evidence in the rocks back then but didn't believe their readings thinking the samples had become conhim tom nated. the results showed the apollo scientists were right all along. >> water that might be used some day by human lunar explorers who return to the moon to do science on the moon and perhaps as a steppingstone out in the rest of the solar system. >> some at nasa imagine a lunar colony will be a base for us from which to leave the earth and perhaps in the far future move on to other worlds and make a new home in our solar system. >> now to another pretty unbelievable find, this one unparalleled in size and value. an amateur treasure hunter unearthed the largest hoard of gold and silver ever found in

britain. the 1,500 pieces date back to well over 1,000 years. archeologists are stunned by the discovery and could change perceptions of early english history. we now get a report. >> for british archeology it really doesn't get more exciting than this. gold. anglo-saxon gold. >> absolutely astonishing. i never, ever in my career thought i'd be holding this kind of treasure. >> something you dream of. >> and this really is just a handful of the hundreds of pieces that have just within found. >> it's just incredible. like all these years we've been picking up crumbs and now we find out we're in the middle of a cake shop. >> crosses, pieces of helmets, some of it with biblical inscriptions. and this is where it all came from. one piece of gold would have

been a significant find, but watch. piece after piece after piece was dug out from the ground. and how did they know it was all here? well, it was a man with a metal detector. >> this is more fun than winning the lottery. >> it was only when terry herbert called in the county archeologist he truly realized the significance of the crime. >> the amount of objects was unbelievable. roughly about 240 objects in boxes. when we first came and saw the one box, he just couldn't stop saying "wow." >> while the amount of gold is absolutely extraordinary, what it actually means, well, the academics haven't even begun to work out what this will really mean to british history. the field is near litchfield and being kept secret but that

is far more than treasure in the countryside. it's a window on an ancient kingdom, mercia, that now has a new place in the history books. the gold is from bazantiam and the gemstones from sri lanka , the barbarian hasegawa suddenly become more sophisticated and the dark ages of britain a little brighter. >> just briefly, a reminder of our top story, scientists are saying they developed a vaccine that cuts the risk of h.i.v. infection, one particular strain of infection by at least more than 30%. first time a vaccine has been shown to give even this limited protection. thanks for being with us on the bbc world news. much more any time you want it on bbc.com. funding for this presentation was made possible by the freeman foundation of new york, stowe, vermont, and honolulu, the newman's own foundation, and the john d. and catherine t. macarthur foundation, union bank, and "bright star" a new
