El consejo de directores del Banco Central Europeo se reúne este jueves para analizar las medidas anticrisis y dar su respaldo financiero a las entidades bancarias. La reunión se celebra un día antes de la crucial conferencia de la UE, donde se abordarán también los problemas del euro y el endeudamiento. Antes del foro, la élite financiera de Europa sostendrá una reunión privada. Los analistas internacionales tratan de avizorar qué temas se tratarán a puertas cerradas por el Club Bilderberg, considerado por muchos como los amos del mundo.
Los nuevos primeros ministros de Grecia e Italia, Lucas Papademos y Mario Monti, tienen mucho en común. Ambos acaban de subir al poder, son economistas y trabajaron en organismos europeos. Pero además, tanto Monti como Papademos pertenecen al club Bilderberg, un selecto grupo de políticos, economistas, empresarios, representantes de los grupos mediáticos más influyentes e incluso de la realeza.

Red Bull Rivals is a one day surf event pitting Oahu's legendary shores, North Shore and South Shore, against each other. Top surfers from each shore battled it out in a head-to-head surf competition for ultimate island bragging rights. To keep things fair, the event was again held on the Eastside of Oahu at Sandy Beach, which is neutral territory and will be the last year at this location. Before the Red Bull Rivals 2009 competition, no surf event had been held at this popular surf location since the Gotcha Pro back in the early '80s. Instead of a traditional purse prize, the teams competed for each others' surfboards used in the competition (similar to racing for pink slips) and, of course, the winning team will earned the ultimate surfing bragging rights.

As brine from the sea ice sinks, a 'brinicle' forms threatening life on the sea floor with a frosty fate.
A bizarre underwater "icicle of death" has been filmed by a BBC crew.
With timelapse cameras, specialists recorded salt water being excluded from the sea ice and sinking.
The temperature of this sinking brine, which was well below 0C, caused the water to freeze in an icy sheath around it.
Where the so-called "brinicle" met the sea bed, a web of ice formed that froze everything it touched, including sea urchins and starfish.
The unusual phenomenon was filmed for the first time by cameramen Hugh Miller and Doug Anderson for the BBC One series Frozen Planet.
Creeping ice
The icy phenomenon is caused by cold, sinking brine, which is more dense than the rest of the sea water. It forms a brinicle as it contacts warmer water below the surface.
Mr Miller set up the rig of timelapse equipment to capture the growing brinicle under the ice at Little Razorback Island, near Antarctica's Ross Archipelago.
"When we were exploring around that island we came across an area where there had been three or four [brinicles] previously and there was one actually happening," Mr Miller told BBC Nature.
The diving specialists noted the temperature and returned to the area as soon as the same conditions were repeated.
"It was a bit of a race against time because no-one really knew how fast they formed," said Mr Miller.
"The one we'd seen a week before was getting longer in front of our eyes... the whole thing only took five, six hours."
Against the odds
The location - beneath the ice off the foothills of the volcano Mount Erebus, in water as cold as -2C - was not easy to access.
"That particular patch was difficult to get to. It was a long way from the hole and it was quite narrow at times between the sea bed and the ice," explained Mr Miller.
"I do remember it being a struggle... All the kit is very heavy because it has to sit on the sea bed and not move for long periods of time."
As well as the practicalities of setting up the equipment, the filmmakers had to contend with interference from the local wildlife.
The large weddell seals in the area had no problems barging past and breaking off brinicles as well as the filming equipment.
"The first time I did a timelapse at the spot a seal knocked it over," said Mr Miller.
But the team's efforts were eventually rewarded with the first ever footage of a brinicle forming.
HOW DOES A BRINICLE FORM?
Dr Mark Brandon
Polar oceanographer, The Open University
Freezing sea water doesn't make ice like the stuff you grow in your freezer. Instead of a solid dense lump, it is more like a seawater-soaked sponge with a tiny network of brine channels within it.
In winter, the air temperature above the sea ice can be below -20C, whereas the sea water is only about -1.9C. Heat flows from the warmer sea up to the very cold air, forming new ice from the bottom. The salt in this newly formed ice is concentrated and pushed into the brine channels. And because it is very cold and salty, it is denser than the water beneath.
The result is the brine sinks in a descending plume. But as this extremely cold brine leaves the sea ice, it freezes the relatively fresh seawater it comes in contact with. This forms a fragile tube of ice around the descending plume, which grows into what has been called a brinicle.
Brinicles are found in both the Arctic and the Antarctic, but it has to be relatively calm for them to grow as long as the ones the Frozen Planet team observed.
