[Credit: Ron Diskin / Caltech] Each time a virus invades a healthy individual, antibodies created by the body fight to fend off the intruders. For some viruses, like HIV, the antibodies are very specific and are generated too slowly to combat the rapidly changing virus. However, in the past few years, scientists have found that some HIV-positive people develop highly potent antibodies that can neutralize different subtypes of the HIV virus. Now, a study involving researchers at Caltech points to the possibility of using these neutralizing antibodies in the development of a vaccine. Guardiola: The priority is a striker. Pep Guardiola has admitted that the club has its eye on Alexis Sánchez (Udinese) and Cesc Fàbregas (Arsenal), although he would rather sign a striker than a midfielder.
He also said that the squad is as keen ever to produce good football. In his first press conference of the 2011/12 season, Pep Guardiola has spoken about the confection of his squad. “The priority is a striker, as we have more players in midfield than up front.” The only proper names that were mentioned were those of Alexis Sánchez and Cesc Fàbregas, two players Guardiola would welcome. “As Andoni [Zubizarreta] has told me, there is enough money to sign them both, and we’ll be trying to do that”.
