  Iran has made considerable advances in science and technology, despite international sanctions. In the biomedical sciences, Iran's Institute of Biochemistry and Biophysics has a UNESCO chair in biology. In 2006, Iranian scientists successfully cloned a sheep at the Royan Research Center in Tehran. Stem cell research is among the top 10 in the world. Iran ranks 15th in the world in nanotechnologies. Iranian scientists outside Iran have made major scientific contributions. In 1960, Ali Javan co-invented the first gas laser, and fuzzy set theory was introduced by Lotfi A. Zadeh.
  
  Cardiologist Tofy Mussivand invented and developed the first artificial cardiac pump, the precursor of the artificial heart. Furthering research in diabetes, the HbA1c was discovered by Samuel Rahbar. Many papers in string theory are published in Iran. In 2014, Iranian mathematician Maryam Mirzakhani became the first woman, and Iranian, to receive the Fields Medal, the highest prize in mathematics.
  
  Iran increased its publication output nearly tenfold from 1996 through 2004, and ranked first in output growth rate, followed by China. According to a study by SCImago in 2012, Iran would rank fourth in research output by 2018, if the trend persisted. The Iranian humanoid robot Sorena 2, which was designed by engineers at the University of Tehran, was unveiled in 2010. The Institute of Electrical and Electronics Engineers (IEEE) has placed the name of Surena among the five most prominent robots, after analyzing its performance.
