The scientific community does not expect the end of the world in 2012 as predicted by the Mayan Prophecy, although increased solar activity may harm satellites and endanger astronauts, a Russian doctor of physical and mathematical sciences said on Monday.
"The solar exposure on near-Earth space will increase, causing perturbations in the atmosphere, which will break space apparatus," Vladimir Kuznetsov who works for the Institute of Earth magnetism, Ionosphere and Radio waves of the Russian Academy of Sciences said. "Enhanced radiation could also endanger cosmonauts".
December 12, 2012 is the end of a calendar created by the ancient Mayan civilization of South America. Over the years, scientists and speculators have proposed numerous astronomical alignments and formulas, which allegedly prove that the end is nigh.
Chilean President Sebastian Pinera has said he hopes 33 trapped miners will be brought to the surface by the end of next week.
Mr Pinera said rescuers were "very close" to getting the men out, and he hoped they would be freed before his planned trip to Europe on 17 October.
Drills digging to reach the miners have been making rapid progress, shortening the expected rescue timetable.
The men have now been trapped underground for two months.
"We are very close to rescuing them," Mr Pinera said, without naming a precise date when the rescue attempt would start.
"I hope we can rescue them before I go to Europe, I want to share that moment with the miners".
Last week the government said the rescue attempt would begin in the second half of October, having previously said it would start in early November.
But the three drills racing to reach the men are advancing rapidly.
Fifa has suspended Nigeria from international competition because of government interference in the sport.
The decision was taken on Monday after several members of the Nigeria Football Federation (NFF) were hauled before the law courts.
Fifa rules prohibit any government intervention with its members.
"The Fifa Emergency Committee decided today...to suspend the NFF with immediate effect on account of government interference," Fifa said.
"During the period of suspension, the NFF will not be able to be represented in any regional, continental or international competitions, including at club level, and also not in friendly matches," the Fifa statement added.
Nigeria's ban from international football leaves their weekend's Africa Cup of Nations qualifier against Guinea in Conakry in doubt.
The world governing body said the ban follows a bid by Nigeria's Minister of Sports to restart the league without relegations from the previous season.
The decision by the Nigeria Sports Commission to force the NFF's secretary-general Musa Amadu to stand down from his position did not go down well with Fifa.
A court action barring the newly-elected members of the NFF also drew the ire of the world governing body.
Brazil's leading presidential hopefuls are preparing to return to campaigning ahead of a second round of elections.
It comes after Dilma Rousseff, backed by outgoing President Luiz Inacio Lula da Silva, failed to secure the 50% of votes needed for an outright victory.
She now enters a 31 October run-off against Social Democratic Party (PSDB) candidate Jose Serra, who won 33%.
Green Party candidate Marina Silva surprised many in the first round by winning 19% of the vote.
Ms Rousseff, of the Workers Party, had been the favourite to win but official results showed she had 46.9% of votes, after apparently losing supporters to former environment minister Ms Silva.
As the results emerged, Ms Rousseff said she was confident that a second round would give her the opportunity to give more detail on her policies to reduce poverty and increase development in Brazil.
She told her supporters the party had traditionally fared well in second round elections - Mr Lula also had to contest a second round in both the 2002 and 2006 elections.
Mr Serra, who lost against Mr Lula in the 2002 run-off, told his supporters he was "going to march to victory" in the election and promised to "build a better country" if he won.
Russia's Rokot carrier rockets will take two European Space Agency (ESA) scientific satellites to orbit in 2012-2013, the head of the ESA Moscow Office said on Monday.
"We have signed contracts for two launches of ESA remote sensing satellites on Russia's Rokot carrier rockets," Rene Pischel said.
The first launch will deliver to orbit the SWARM satellite, which will survey the geomagnetic field of the Earth.
It is unknown what spacecraft will be conveyed into space on the second Rokot, but the launch is expected to take place in 2012-2013, Pischel said.
The Rokot launch vehicle is a modified version of the Russian RS-18 (SS-19 Stiletto) intercontinental ballistic missile. It uses the two original lower stages of the ICBM, in conjunction with a Breeze-KM upper-stage for commercial payloads.
The ESA launched its CryoSat-2 satellite onboard Russia's Dnepr booster in this April. The satellite is designed to monitor the effects of global warming on polar glaciers and has a life span of three years.
