In the Graeco-Roman world, practitioners of magic were known as magi (singular magus), a "foreign" title of Persian priests. Apuleius, defending himself against accusations of casting magic spells, defined the magician as "in popular tradition (more vulgari)... someone who, because of his community of speech with the immortal gods, has an incredible power of spells (vi cantaminum) for everything he wishes to." Pliny the Elder offers a thoroughly skeptical "History of magical arts" from their supposed Persian origins to Nero's vast and futile expenditure on research into magical practices in an attempt to control the gods. Philostratus takes pains to point out that the celebrated Apollonius of Tyana was definitely not a magus, "despite his special knowledge of the future, his miraculous cures, and his ability to vanish into thin air".
What word was used by the Romans for practitioners of magic?
****
The answer: magi

Uranium metal heated to 250 to 300 C (482 to 572 F) reacts with hydrogen to form uranium hydride. Even higher temperatures will reversibly remove the hydrogen. This property makes uranium hydrides convenient starting materials to create reactive uranium powder along with various uranium carbide, nitride, and halide compounds. Two crystal modifications of uranium hydride exist: an form that is obtained at low temperatures and a form that is created when the formation temperature is above 250 C.
Along with uranium carbide and halide, what type of compound is often created with uranium hydride?
****
The answer: nitride

Interspersed repeats mainly come from transposable elements (TEs), but they also include some protein coding gene families and pseudogenes. Transposable elements are able to integrate into the genome at another site within the cell. It is believed that TEs are an important driving force on genome evolution of higher eukaryotes. TEs can be classified into two categories, Class 1 (retrotransposons) and Class 2 (DNA transposons).
What is the main source of interspersed repeats?
****
The answer: Transposable elements

The on-again, off-again armistice negotiations continued for two years, first at Kaesong, on the border between North and South Korea, and then at the neighbouring village of Panmunjom. A major, problematic negotiation point was prisoner of war (POW) repatriation. The PVA, KPA, and UN Command could not agree on a system of repatriation because many PVA and KPA soldiers refused to be repatriated back to the north, which was unacceptable to the Chinese and North Koreans. In the final armistice agreement, signed on 27 July 1953, a Neutral Nations Repatriation Commission, under the chairman Indian General K. S. Thimayya, was set up to handle the matter.
When was the armistice agreement finally signed?
****
The answer:
27 July 1953
