At Rutgers University, joined Gerstein’s group in 2003 to begin investigating pseudogene activity and evolution. Both authors were initially interested in studying molecular structure and simulation, as described in Gerstein’s previous article for Scientific American with Michael Levitt, “Simulating Water and the Molecules of Life” (November 1998). But Gerstein and Zheng were intrigued by the enormous data analysis challenges posed by the sequencing of the human genome and chose to start scanning and sifting the regions of DNA between genes.

Hydrocarbon jet fuels are easier to handle but provide less energy per weight unit. Propulsion efficiency, a measure of relative engine effectiveness, is the jet thrust per weight unit flow rate of propellant. COPYRIGHT 2006 SCIENTIFIC AMERICAN, INC. S. Air Force’s HyTech and X-51A Scramjet Engine Demonstrator programs [see main article], other national and international research efforts are developing scramjet engine technology. PROGRAM DATES INSTITUTION ACHIEVEMENTS OR GOALS Hyper-X 1996– 2004 NASA The Hyper-X (X-43A) effort flew small test vehicles to demonstrate hydrogenfueled scramjet engines.

In general, jets work by compressing atmospheric air, combining it with fuel, burning the mixture and then expanding the combustion products out the back to provide thrust. Most familiar to commercial airline passengers are gas turbine engines, which contain five basic components: an air inlet; a compressor (a wheel of airfoils on a rotating shaft) that sucks in air and raises its pressure; a combustion chamber (or combustor) into which fuel is injected and burned; a turbine wheel that spins when hot combustion gases rush past its airfoils to drive the compressor wheel shaft; and a nozzle through which the high-temperature exhaust expands to generate thrust.
