Al-Azhar University

Located in Cairo, Egypt, Al-Azhar University was founded in 972 CE as a madrasa—a place of Islamic learning. By teaching numerous subjects in the same place, it was one of the first universities in the world and the only one to survive as a modern university. Historically, students primarily studied the Qur’an and Islamic law. Today, the university is the world’s chief center of Arabic literature and Islamic learning. When did it begin teaching a wide range of secular subjects? Discuss

XYY Syndrome

XYY syndrome is a chromosomal anomaly characterized by the presence of one X-chromosome and two Y-chromosomes. Some medical geneticists question whether the term “syndrome” is appropriate for this sex-linked trisomy, because afflicted males are physically normal—though they tend to be above average in height—and the vast majority of those affected do not know that they possess the extra chromosome. About 1 in 1,000 boys are born with this condition. How does the chromosomal disorder develop? Discuss

In a Flash

As storm clouds develop, the temperature at the top of the clouds becomes much cooler than that at the bottom. For reasons that scientists still do not understand, this temperature difference results in the accumulation of negatively charged particles near the base and positively charged particles near the top of the storm cloud. This buildup of electrical charge causes a high-voltage discharge in the form of lightning. What is sheet lightning, and how does it differ from forked lightning? Discuss
