Just three 45-minute runs a week were enough to reverse the aging process in mice, according to researchers at McMaster University in Canada. Scientists genetically modified the mice so their mitochondria would break down faster, causing the mice to age faster. Half of the mice were then put on an…

Switzerland also put on hold plans to build and replace nuclear plants and Austria’s environment minister called for atomic stress tests to make sure Europe’s nuclear facilities are “earthquake-proof”. On Tuesday there will be an emergency meeting of European Union nuclear safety authorities and operators to assess Europe’s preparedness in case of an emergency. After two hydrogen explosions at the Fukushima Daiichi reactor in Japan, the German chancellor Angela Merkel decided to re-examine her controversial decision last year to renew 17 nuclear plants for an average of 12 years. Merkel announced a “three-month moratorium” while each plant was given a thorough safety check.As a result, Germany’s two oldest nuclear power stations will be taken off the grid imminently, as they have already reached the end of their lifespan. They will only be reconnected if they pass strict safety checks, the chancellor said in Berlin. Both plants are situated in states where there are regional elections later this month. One, Biblis A, is in Hesse, western Germany, and the other, Neckarwestheim I, is in the southwestern state of Baden-Württemberg. Merkel’s Christian Democratic Party (CDU) is at risk of losing Baden-Württemberg for the first time since 1953, leading commentators to suggest the decision was partly politically motivated. Most Germans are opposed to nuclear power, and Japan’s problems have raised fears of the technology and strengthened the nuclear lobby and the opposition Green Party. A poll for the news channel N-TV on Monday showed 88% of Germans wanted plants shut sooner rather than later. Merkel said Germany needs to continue using nuclear power while it switches over to renewable power sources to keep energy affordable and to ensure it is not dependent on importing nuclear energy from other countries where safety standards might be lower than those in Germany. However, the events in Japan “teach us that risks that were considered absolutely improbable are in fact not completely improbable,” she added. The Swiss energy minister, Doris Leuthard, said the suspension would affect all “blanket authorisation for nuclear replacement until safety standards have been carefully reviewed and if necessary adapted”. Swiss regulatory authorities had given their stamp of approval to three sites for new nuclear power stations after the plans were submitted in 2008. European energy commissioner Günther Oettinger said safety at older German nuclear power stations must be checked rigorously, and he refused to rule out closures. He told Deutschlandfunk radio that the crisis in Japan had changed the world and brought into question what had been seen as safe and manageable. The government’s decision last year to keep Germany’s nuclear plants running for 12 years beyond their original shutdown date had stirred large-scale protests. On Saturday, anti-nuclear protesters formed a 45km (27 mile) human chain from the city of Stuttgart to an older nuclear power plant that will be kept running longer because of the new policy. Between 50,000 and 60,000 demonstrators took part, according to police and organisers. In the US, Barack Obama reaffirmed his support for nuclear power. At a White House press conference, the head of the Nuclear Regulatory Commission (NRC), Gregory Jaczko, said the 104 reactors in the US were built to withstand earthquakes and tsunamis. “Right now we believe we have a very strong programme in place,” he said, adding that Japan had requested assistance from the NRC and two experts on boiling water reactors were en route. Jaczko in his remarks gave no details on the magnitude of natural disasters US reactors could withstand. Twenty-three are identical models of the two reactors which exploded in Japan. Twelve are newer versions of that model. He also said any release of radiation would be highly dispersed by the time it travelled across the Pacific to Hawaii or the West Coast. Jaczko’s appearance was the second show of confidence in the nuclear industry since Sunday. The White House said in a statement that Obama continued to see nuclear power as part of America’s energy portfolio. “The president believes that meeting our energy needs means relying on a diverse set of energy sources that includes renewables like wind and solar, natural gas, clean coal and nuclear power. “Information is still coming in about the events unfolding in Japan, but the administration is committed to learning from them and ensuring that nuclear energy is produced safely and responsibly here in the US,” the statement said.

The navy captured 61 pirates fleeing the battle and the ensuing fire that broke out aboard the hijacked vessel. A pirate in Somalia threatened Indian sailors and the government with attacks in retaliation for the arrests. The Indian navy said a patrol aircraft spotted the pirate mothership on Friday while responding to another vessel reporting an attack. The pirates aborted the hijack attempt and tried to escape on the mothership. When the Indian navy closed in on Sunday night, the pirates fired on them. The hijacked vessel caught fire when Indian vessels returned fire, the navy said. The pirates had hijacked the Mozambique-flagged Vega 5 in December and had used it as a mothership. Indian sailors rescued 13 crew members from the Vega 5 about 700 miles off Kochi in southern India, the statement said. The pirates were carrying about 80 to 90 small arms or rifles and a few heavier weapons, it said. The statement did not describe any casualties among the navy, the fishermen or the pirates. The pirates were being taken to Mumbai to be prosecuted for attacking the Indian ships. Piracy has plagued the shipping industry off east Africa for years, but violence and ransom demands have escalated, with pirates holding around 30 ships and more than 660 hostages as of last month. A self-described pirate in Somalia, who gave his name as Bile Hussein, said the arrests would lead to “trouble” for Indian sailors and ships. “They better release them, considering their people travelling in the waters, or we shall jail their people like that,” he said. “We are first sending a message to the Indian government of releasing our friends in their hands or else they have to be ready for their citizens to be mistreated in the near future.” The Indian navy’s third anti-piracy operation this year followed the capture of 28 Somali pirates last month and 15 in January. Both groups are to be prosecuted in Mumbai. Indian warships have been escorting merchant ships as part of international anti-piracy surveillance in the area since 2008.

Members of the California state assembly in Sacramento from both main parties have introduced a bill that would put politicians in the same class of workers vulnerable to violence as agents who arrange bail for defendants or jewellery shop owners. The bill would grant California’s representatives to Congress in Washington and its state politicians a “good cause” classification, entitling them to carry hidden guns while in the state on the grounds of self-defence. The legislation , sponsored by two Democrats and one Republican politician in the Californian assembly, specifically refers to January’s mass shooting in Tucson in which six people were killed and 13 injured, including congress member Gabrielle Giffords, who was shot in the head. Lou Correa, a Republican member of the Californian senate, told the Los Angeles Times that, in the wake of Tucson, he was considering keeping a stun gun in his office and said one of his employees had asked for increased protection from potentially violent members of the public. “I’ve had guys physically come up to me ready to punch me out,” Correa said, adding he had received email death threats. The Californian initiative highlights a peculiar trend since the Tucson shooting. Far from inspiring a major change in the US attitude towards personal weapons, which is among the most gun-friendly in the world, it has prompted a rash of legislative moves across the country designed further to loosen gun controls. The Legal Community Against Violence campaign estimates that there are currently 470 gun bills being considered around the US, of which 273 would make it easier for people to buy and carry weapons. Even in Arizona itself, where the Giffords shooting took place, there are 16 bills now pending, most of which favour the gun owner rather than the potential victims of gun outrages. One potentially significant shift in the other direction is that President Barack Obama appears to be moving towards tightening gun controls by making background checks on purchasers more stringent. In an article in the Arizona Daily Star, Obama said 2,000 Americans had been killed by guns since the Tucson massacre on 8 January. Every year, about 100,000 people are killed or injured as a result of gun violence in the US. “We have a responsibility to do everything we can to put a stop to it,” Obama wrote, highlighting the fact that Jared Loughner, who is charged with the Tucson shooting, was able to buy a gun, despite having been deemed by the US army to be unfit for service and by his college to be too unstable to study there. Obama went on to propose that the background check before gun sales should be made more rigorous and speedy. “None of us should be willing to remain passive in the face or violence or resigned to watching helplessly as another rampage unfolds on television.” US gun control California Gabrielle Giffords United States Ed Pilkington guardian.co.uk

Mustafa Gheriani, spokesman for the revolutionary national council in its stronghold of Benghazi, said the appeal was to be made by a delegation meeting the French president, Nicolas Sarkozy, and the US secretary of state, Hillary Clinton, in Paris on Monday, as G8 foreign ministers gathered there to consider whether to back French and British calls for a no-fly zone over Libya. “We are telling the west we want a no-fly zone, we want tactical strikes against those tanks and rockets that are being used against us and we want a strike against Gaddafi’s compound,” said Gheriani. “This is the message from our delegation in Europe.” Asked if that meant that the revolutionary council wanted the west to assassinate Gaddafi, Gheriani replied: “Why not? If he dies, nobody will shed a tear.” But with diplomatic wrangling focused on the issue of the no-fly zone, there appeared to be little immediate prospect of a foreign military assault on Gaddafi’s forces, let alone an air strike against the Libyan dictator. The Libyan revolutionary leadership made the appeal as Gaddafi’s airforce bombed Ajdarbia, a town of 135,000 people that is the last major obstacle for his forces before Benghazi, the seat of the revolutionary council. Those attacks strengthened the hand of France and Britain in pressing for intervention. Paris said it wants to see a no-fly zone “as fast as possible”. The move is backed by the Arab League, which may ease the way to agreement at the UN security council. France and Britain are also expected to push the move at a Nato meeting on Tuesday. But the rebels’ appeal is also a recognition that while a no-fly zone would provide a boost to them, their military defeats of recent days have largely been under an onslaught of rockets and shells, and air strikes have been relatively peripheral. A no-fly zone alone may not be enough to prevent the continued advance of Gaddafi’s forces toward Benghazi, the revolutionaries’ de facto capital. So far no western nation has explicitly supported attacks on Gaddafi’s forces separate from enforcing a no-fly zone. The issue is complicated by overwhelming opposition even among the insurgents to foreign forces becoming involved on the ground, in large part because of strong views about the consequences of the invasion of Iraq. The talks are being closely watched in Benghazi and other areas under the control of the revolutionaries where Libyans are increasingly concerned at the direction of the conflict and the west’s failure, so far at least, to follow through on calls for Gaddafi to go with action in support of the rebellion. A large French flag hangs on the front of the courthouse used as the revolutionary council’s headquarters after Paris recognised the rebel leadership, and the tricolour is often seen on the streets of Benghazi. But Libyans are also increasingly vocal in their criticism of Washington in particular for what is seen as a failure to back up rhetoric against the regime. However, Gheriani said that if the west failed to offer practical help to the revolutionaries to free themselves from Gaddafi’s rule it risked frustrated Libyans turning to religious extremists. “The west is missing the point. The revolution was started because people were feeling despair from poverty, from oppression. Their last hope was freedom. If the west takes too long – where people say it’s too little, too late – then people become a target for extremists who say the west doesn’t care about them,” he said. “Most people in this country are moderates and extremists have not been able to penetrate them. But if they get to the point of disillusionment with the west there will be no going back.” Although the revolutionary leadership is reluctant to concede that it is enduring significant military setbacks, Gaddafi’s forces have driven them from two small towns and back about 150 miles to the edge of Ajdarbia. On Sunday the rebel army fled in the face of a barrage of rockets and shells as Tripoli’s army took Brega, a day after seizing the strategic oil centre of Ras Lanuf, 90 miles away. The rebels’ military leader, Abdel Fattah Younis, Gaddafi’s former interior minister, has promised a vigorous defence of Ajdarbia to block the government’s advance on Benghazi, 90 miles along the coastal road. Younis has said he believes Gadaffi’s supply lines are overstretched and his forces demoralised. He also said that street fighting in a town will be a more even contest than facing rocket barrages in largely open desert. But the defences on display on Monday, which included a handful of tanks and armoured vehicles and small artillery guns, did not look strong. The revolutionaries claimed to be back in Brega, but provided no evidence and prevented reporters from travelling towards the town. On Monday Gaddafi’s forces also attacked Zuwara, a town of 40,000 people about 60 miles west of Tripoli and near the Tunisian border. Residents described shelling of their neighbourhoods and said armoured vehicles were in the heart of the town. “I can see the tanks from where I am now and they are around 500 metres from the centre of Zuwara,” Tarek Abdullah told Reuters by telephone. “There are still clashes but I think soon the whole town will fall into their hands.” But the pressure appeared to be off the only major city in the west still held by the rebels, Misrata, 130 miles east of the capital. Tripoli’s assault apparently stalled amid claims of a mutiny within the ranks of the besieging government forces. Libya Muammar Gaddafi Middle East Protest Chris McGreal guardian.co.uk
