For example, newborns are routinely screened for certain enzyme defects, such as phenylketonuria (PKU) and galactosemia.nzyme defect: A disorder resulting from a deficiency (or functional abnormality) of an enzyme.

It takes Saturn 29.45 years (or 10,759 days) to orbit the Sun. Astronomers call the length of time an object takes to go around the Sun its orbital period. So the orbital period of Saturn is 29.45 years. Saturn. Image credit: Hubble. One of the interesting facts about Saturn is that its axis is tilted off the plane of the ecliptic (just like Earth).
A day on Saturn just got a few minutes shorter, if new calculations are correct. Using data collected by NASA's Cassini, Pioneer and Voyager spacecraft, scientists have revised the ringed planet's rotation period to 10 hours, 32 minutes and 35 secondsâabout 15 minutes shorter than an estimate made only last year.
