Scientists discover a superbug in the cold waters of Antarctica


All medicine is in some way, a tiny fight against aggressors who threaten us. A battle that began early twentieth century to win thanks to the arrival of penicillin by Alexander Fleming discovered or at least so we thought.

Those strains of Penicillium chrysogenum promised to protect us from bacteria that cause many diseases and infections. No doubt, antibiotics represented a giant step forward in the recent history of medicine.

But evolution works both ways and bacteria are also involved in this game. Gradually, antibiotics are losing strength and some of the organisms that perished before now have been adapted and have become resistant to almost everything.

Since the discovery in 1947 in England the first penicillin-resistant pathogens, Staphylococcus aureus, have emerged more and more bacteria can survive a wide spectrum of antibiotics.

The most widespread example of these resistant bacteria Escherichia coli is the famous, whom many remember as a virulent strain was the cause of the recent outbreak in Germany last year.

Now, scientists at Sweden's Uppsala University have discovered in the cold waters of Antarctica a new bacteria that can resist almost any antibiotic.

The team led by Björn Olsen found in samples taken in the Antarctic ocean water near the Antarctic research stations there was a new strain of the bacterium Escherichia coli genetically capable of producing ESBL enzyme and destroy powerful antibiotics such as penicillin or cephalosporin among many others.

As is well recognized Olsen's team in their study, a superbug and could be very dangerous, so have started checks of infection in animals in the area. So far the penguins studied are free of ESBL and in these days are looking into whether gulls may have been exposed to this strain of E.coli.

That the bacteria was found in the waters near research stations located in Antarctica could be a sign that human activity has had something to do with their appearance.

 As says Björn Olsen in New Scientist, that bacteria such as this may have achieved even Antarctica gives us an idea of ​​how far we can get this problem.

The "energy loss" of the Earth accumulates in the oceans


Two years ago, scientists at the National Center for Atmospheric Research in Boulder, Colorado, published a study which found inconsistencies between satellite observations of heat on Earth, and measurements of ocean warming, increasing evidence that he had "lost energy "in the system on the planet.

Where does it go? Or, they wondered, is there an error in the monitoring of energy, so that it was absorbed and emitted by the sun back into space?

An international team of atmospheric scientists and oceanographers, led by Norman Loeb Center at NASA Langley in Hampton, Virginia, and Graeme Stephens of the Jet Propulsion Laboratory in Pasadena, California, began to investigate the mystery.

We used 10 years of data, ranging from 2001 to 2010 - from the databases of the center itself and the CERES instrument Langley (Experiment Radiant Energy System of the Earth) to measure changes in the net radiation balance in the upper atmosphere.

The CERES data were combined with estimates of heat content of Earth's oceans from three independent sources of ocean sensor.

Their analysis, summarized in a NASA-led study published January 22 in the journal Nature Geoscience, found that satellite measurements and ocean broad agreement, once the observational uncertainties are taken into account.

"One of the things we wanted to do was a more rigorous analysis of uncertainties," said Loeb. "When we did, we conclude that the energy lost in the system was not really supported with data. Our data show that Earth has been accumulating heat in the ocean at a rate of half watt per square meter, with no signs of a decline, "said Loeb. "This extra energy will eventually find its way back into the atmosphere and increasing temperatures on Earth."

Scientists generally agree that 90 percent of the excess heat associated with increased concentrations of greenhouse gases stored in the oceans of Earth. If released into the atmosphere, an accumulation of half watt of heat per square meter could increase global temperatures by more than 0.3 degrees Celsius.

Loeb said the results demonstrate the importance of using multiple metrics over time and demonstrate the need for continuous improvement in the way they measure the energy flows on Earth.

The scientific team from the National Center for Atmospheric Research measures inconsistencies between 2004 and 2009 from satellite observations of the heat balance of the Earth and measuring the rate of heating of the upper ocean. They said that the inconsistencies were proof that he had "lost energy".

Shipwreck Hunters Find Second 'UFO' on Ocean Floor January 30,2012

A team of shipwreck hunters that found a strange circular object on the floor of the Baltic Sea in 2011 now says they have discovered visual evidence of a second disc-like shape some 200 meters from the original find-

Fragments of lava seen on the surface of El Hierro, Spain


El Hierro is still shaking vigorously. Lava fragments have large surfaced during the last hours in the vicinity of the Canary island of El Hierro as a result of submarine volcano just over three months erupted near the fishing village of La Restinga.

Some of the lava fragments that have come near the island have more than three meters long and violently explode before sinking, announced today in a statement the Canary Islands Government.

The most violent demonstrations took place earlier in the day. Finally, 12.00 hours on the issue began to decline in area and in the afternoon was observed only slight bubbling ring.

From the boat Salvamar Adhara, Maritina Rescue, have collected some of these fragments.
