‘Brazuca’ : The new FIFA World Cup ball unveiled

Sports goods manufacturer Adidas unveiled the new ball for 2014 World Cup – called the Brazuca,” in honor of Brazil at a ceremony in Rio de Janeiro. Adidas has been following the tradition of providing the official ball for every World Cup tournament since 1970. 

What does Brazuca mean?

The word “Brazuca” has a dual meaning, used as a term for Brazilians living overseas – including its many footballers – but also as slang used to describe national pride or anything “Brazilianish”.  The ball is decorated with a ribbon design in shades of blue, gold and green, which the manufacturer says represents the traditional “wish bracelets” worn in Brazil.
The ball will be introduced in the inaugural game of FIFA World Cup 2014 on June 12, 2014 in Sao Paulo, and will be played with until the final on July 13, 2014 in Rio de Janeiro in Brazil.

Previously, Adidas manufactured a ball named “Jabulani” for the FIFA World Cup 2010 in held in South Africa.

Oxford researchers develop new malaria vaccine

In a major scientific development, scientists at Oxford University have developed a new malaria vaccine which can guard against the deadly mosquito-borne disease.

The vaccine has shown promising results in the first clinical trial in which some of the adult volunteers were completely protected against malaria.
It’s the first time that a vaccine has been shown to have a protective effect through a sufficiently high immune response involving cells called CD8 T cells. It is CD8 immune cells that are seen to vanguard a protective response against malaria in similar studies in mice.

How this vaccine is different from existing vaccines?

At present, every vaccine in use generates antibodies. But there are two divisions to the body’s immune system for combating infection: antibodies and T cells. The latest vaccine is different in a way that it aims to induce an immune response involving T cells particularly CD8+ T cells. CD8 T cells are vital because they are the main killer cells in the immune system. They can attack nearly all types of infected cells – in this case liver cells infected with the malaria parasite.
