Problem: A much smaller number of people are insensitive to pain due to an inborn abnormality of the nervous system, known as "congenital insensitivity to pain". Children with this condition incur carelessly-repeated damage to their tongues, eyes, joints, skin, and muscles. Some die before adulthood, and others have a reduced life expectancy.[citation needed] Most people with congenital insensitivity to pain have one of five hereditary sensory and autonomic neuropathies (which includes familial dysautonomia and congenital insensitivity to pain with anhidrosis). These conditions feature decreased sensitivity to pain together with other neurological abnormalities, particularly of the autonomic nervous system. A very rare syndrome with isolated congenital insensitivity to pain has been linked with mutations in the SCN9A gene, which codes for a sodium channel (Nav1.7) necessary in conducting pain nerve stimuli.

Problem: Scientists associated with BYU have created some notable inventions. Philo T. Farnsworth, inventor of the electronic television, received his education at BYU, and later returned to do fusion research, receiving an honorary degree from the university. Harvey Fletcher, also an alumnus of BYU, inventor of stereophonic sound, went on to carry out the now famous oil-drop experiment with Robert Millikan, and was later Founding Dean of the BYU College of Engineering. H. Tracy Hall, inventor of the man-made diamond, left General Electric in 1955 and became a full professor of chemistry and Director of Research at BYU. While there, he invented a new type of diamond press, the tetrahedral press. In student achievements, BYU Ad Lab teams won both the 2007 and 2008 L'Oreal National Brandstorm Competition, and students developed the Magnetic Lasso algorithm found in Adobe Photoshop. In prestigious scholarships, BYU has produced 10 Rhodes Scholars, four Gates Scholars in the last six years, and in the last decade has claimed 41 Fulbright scholars and 3 Jack Kent Cooke scholars.

Problem: Following the fracture of the Mongol Empire in 1256, Hulagu Khan, grandson of Genghis Khan, established the Ilkhanate in Iran. In 1370, yet another conqueror, Timur, followed the example of Hulagu, establishing the Timurid Empire which lasted for another 156 years. In 1387, Timur ordered the complete massacre of Isfahan, reportedly killing 70,000 citizens. The Ilkhans and the Timurids soon came to adopt the ways and customs of the Iranians, choosing to surround themselves with a culture that was distinctively Iranian.
Who established an Ilkhanate in Iran after the break up of the Mongol Empire in 1256?
