Is one of a thousand marine species have been inventoried in the peninsula of Guanahacabibes.

An odd-shaped seashell vuvuzela ball has been discovered by a Spanish-Cuban team of researchers in Guanahacabibes (Cuba), 750 km south of the platform "Macondo", the oil spill has caused a major ecological disaster the history of mankind.

The finding has occurred in the reef ecosystem Guanahacabibes, where the research team performed since 2006 the inventory of marine shellfish waters are home to the peninsula, according to Efe recounts one of the researchers, Leopoldo Moro, Biodiversity Service Canary Islands Government.

Leopoldo Moro noted that this curious shell, a true living fossil "worthy of being the mascot of the last Football World Cup in South Africa", has proposed a new genre, "Globocornus, Globus = globe, ball, and cornus = trumpet (trumpet ball). "

It has also dedicated his discovery to Charles Darwin on the occasion of celebrating the International Year of Biodiversity and the 150 anniversary of the publication of the Origin of Species ", a masterpiece that changed the view of life on the planet, details marine biologist.

So the snail has been dubbed "Globocornus darwini" and is one of a thousand marine species have been inventoried in the peninsula of Guanahacabibes by this team of Spanish and Cuban researchers found among the authors of the discovery, Jesus Ortea, University of Oviedo, and Jose Espinosa, Institute of Oceanology of Cuba.

Both are leaders of a team which also includes, in addition to Leopoldo Moro, Manuel Caballer, the Venezuelan Institute for Scientific Research (IVIC) that during the past six years have prepared the inventory marine western tip of Cuba.

According to Leopoldo Moro accurate, this area is considered a "hot spot" of biodiversity because the larvae are carried by ocean currents toward the American coast of the Gulf of Mexico and Florida, larvae that have the task of restoring the immediate future marine biodiversity oil affected by the disaster, he said.

In parallel, and the underwater cave Brains in the Canary island of Tenerife, the same research team has discovered another cave snail, the "Neritilia nataliae" the third Atlantic species of a genus with representatives in Sao Thome and the Caribbean.

Aspirin reduces colon cancer risk

A low dose of aspirin may reduce the incidence of colon cancer by a quarter and deaths by one third, according to a new study.

But experts say that the side effects of aspirin such as bleeding and stomach problems are too disturbing to people who are not at high risk of the disease begin to take it just for that reason.

Previous studies have found that a daily dose of at least 500 milligrams of aspirin may prevent colon cancer, but the adverse effects of a dose as high outweighed the benefits. Now researchers say that a low dose, equivalent to a regular aspirin or child also seems to work.

European researchers found 20-year results of four studies involving more than 14 000 subjects who were originally made to study the use of aspirin in preventing stroke.

They found that those taking regular aspirin or infant daily for about six years reduced the risk of colon cancer by 24% and deaths from the disease fell 35%. These results were compared with those taking placebo or nothing. It seems to be no difference in taking over infant dose aspirin.

The study concluded that even low doses of aspirin may reduce colon cancer suggests that the drug could be used for the prevention of cancer, but should not start taking aspirin daily without consulting a doctor.

The European studies used baby aspirin 75 milligrams and 300 milligrams of aspirin regularly. In the United States are the equivalent of 81 to 325 milligrams.

If taken in large doses for a long time, aspirin can irritate the stomach, intestines and stomach, causing injuries and bleeding.

Some researchers said that aspirin may benefit certain individuals.

"Anyone who has any risk factors such as family history (colon cancer) or previous polyp definitely should take aspirin," said Peter Rothwell, a professor at the University of Oxford and one of the authors of the report.

No funding was provided for the study, which was published online Friday in the journal Lancet Rothwell and some of his co-authors were paid by several pharmaceutical companies that produce blood thinners like aspirin.

The evidence discussed in the Lancet study were made before the widespread introduction of screening tests such as sigmoidoscopy and colonoscopy, which reduces the probability of death from colon cancer from 40% to 70%.
