Science and technology

Argentina has contributed many distinguished doctors, scientists, and inventors to the world, including three Nobel Prize laureates in sciences.


Argentines have been responsible for major breakthroughs in world medicine. René Favaloro developed the techniques and performed the world's first ever coronary bypass surgery, and Francisco de Pedro invented a more reliable artificial cardiac pacemaker. Medicine's Nobel laureate Bernardo Houssay discovered the role of pituitary hormones in regulating glucose in animals; Medicine's Nobel laureate César Milstein did extensive research in antibodies; and Chemistry's Nobel laureate Luis Leloir discovered how organisms store energy converting glucose into glycogen, and the compounds which are fundamental in metabolizing carbohydrates. Luis Agote performed one of the first two blood transfusions with pre-stored blood in history. Enrique Finochietto designed operating table tools such as the surgical scissors that bear his name ("Finochietto scissors"), and a rib-spreader. Roberto Zaldívar is a pioneer in laser-eye procedures and research. Argentine research has led to advancement in wound-healing therapies, heart disease, and in several forms of cancer.
Argentina's nuclear program is highly advanced. Argentina developed its nuclear program without being overly dependent on foreign technology. Nuclear facilities with Argentine technology have been built in Peru, Algeria, Australia, and Egypt. In 1983, the country admitted having the capability of producing weapon-grade uranium, a major step to assemble nuclear weapons. Since then Argentina has pledged to use nuclear power only for peaceful purposes.
In other areas, Juan Vucetich, a Yugoslavian immigrant, was the father of modern fingerprinting(dactiloscopy). (see fingerprint), Raúl Pateras de Pescara demonstrated the world's first flight of a helicopter, Hungarian-Argentine László Bíró mass-produced the first modern ball point pens, and Eduardo Taurozzi developed the more efficient pendular combustion engine. Juan Maldacena, an Argentine-American scientist, is a leading figure in string theory. An Argentine satellite, the PEHUENSAT-1 was successfully launched on January 10, 2007 using the PSLV .
